Why invest in cryptocurrency in 2020?

Why invest in cryptocurrency in 2020?
Hello! 👋🏻 In this post, we will tell you why to invest in cryptocurrencies in 2020
📌 After the fall in the price of Bitcoin in 2018, many investors who are not familiar with the crypto market got the impression that cryptocurrencies are not a reliable asset.
📌 However, their more experienced colleagues in crypto trading have long known about the cycles of the crypto market and the fall in BTC was expected almost immediately after the halving.
📌 Although Bitcoin remains a valuable cryptocurrency asset, there are other, more attractive ways to profit from cryptocurrencies in 2020.

💡 PoS mining is the best solution in 2020

🔹 PoS mining is mining based on the Proof-of-Stake algorithm. Unlike the usual Proof-of-Work mining, you do not need expensive equipment. It is enough to keep the coins in your wallet and you will receive a fixed percentage of the coins you are holding.
🔹 Those who are involved in PoS mining and store money in a stake are usually called "forgers".
🔹 Usually, the percentage reward for PoS mining is about 5-6%.
✅ PosBit is an excellent tool for those who prefer passive income. A portfolio of PoS coins has never been so convenient to collect at once in one place. You no longer need to register on many exchanges in search of the desired coins. In addition, the number of coins will expand every 2 weeks.
📢 Go to PosBit and start building your staking portfolio now: http://posbit.io/

Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Streamr Network: Performance and Scalability Whitepaper


https://preview.redd.it/bstqyn43x4j51.png?width=2600&format=png&auto=webp&s=81683ca6303ab84ab898c096345464111d674ee5
The Corea milestone of the Streamr Network went live in late 2019. Since then a few people in the team have been working on an academic whitepaper to describe its design principles, position it with respect to prior art, and prove certain properties it has. The paper is now ready, and it has been submitted to the IEEE Access journal for peer review. It is also now published on the new Papers section on the project website. In this blog, I’ll introduce the paper and explain its key results. All the figures presented in this post are from the paper.
The reasons for doing this research and writing this paper were simple: many prospective users of the Network, especially more serious ones such as enterprises, ask questions like ‘how does it scale?’, ‘why does it scale?’, ‘what is the latency in the network?’, and ‘how much bandwidth is consumed?’. While some answers could be provided before, the Network in its currently deployed form is still small-scale and can’t really show a track record of scalability for example, so there was clearly a need to produce some in-depth material about the structure of the Network and its performance at large, global scale. The paper answers these questions.
Another reason is that decentralized peer-to-peer networks have experienced a new renaissance due to the rise in blockchain networks. Peer-to-peer pub/sub networks were a hot research topic in the early 2000s, but not many real-world implementations were ever created. Today, most blockchain networks use methods from that era under the hood to disseminate block headers, transactions, and other events important for them to function. Other megatrends like IoT and social media are also creating demand for new kinds of scalable message transport layers.

The latency vs. bandwidth tradeoff

The current Streamr Network uses regular random graphs as stream topologies. ‘Regular’ here means that nodes connect to a fixed number of other nodes that publish or subscribe to the same stream, and ‘random’ means that those nodes are selected randomly.
Random connections can of course mean that absurd routes get formed occasionally, for example a data point might travel from Germany to France via the US. But random graphs have been studied extensively in the academic literature, and their properties are not nearly as bad as the above example sounds — such graphs are actually quite good! Data always takes multiple routes in the network, and only the fastest route counts. The less-than-optimal routes are there for redundancy, and redundancy is good, because it improves security and churn tolerance.
There is an important parameter called node degree, which is the fixed number of nodes to which each node in a topology connects. A higher node degree means more duplication and thus more bandwidth consumption for each node, but it also means that fast routes are more likely to form. It’s a tradeoff; better latency can be traded for worse bandwidth consumption. In the following section, we’ll go deeper into analyzing this relationship.

Network diameter scales logarithmically

One useful metric to estimate the behavior of latency is the network diameter, which is the number of hops on the shortest path between the most distant pair of nodes in the network (i.e. the “longest shortest path”. The below plot shows how the network diameter behaves depending on node degree and number of nodes.

Network diameter
We can see that the network diameter increases logarithmically (very slowly), and a higher node degree ‘flattens the curve’. This is a property of random regular graphs, and this is very good — growing from 10,000 nodes to 100,000 nodes only increases the diameter by a few hops! To analyse the effect of the node degree further, we can plot the maximum network diameter using various node degrees:
Network diameter in network of 100 000 nodes
We can see that there are diminishing returns for increasing the node degree. On the other hand, the penalty (number of duplicates, i.e. bandwidth consumption), increases linearly with node degree:

Number of duplicates received by the non-publisher nodes
In the Streamr Network, each stream forms its own separate overlay network and can even have a custom node degree. This allows the owner of the stream to configure their preferred latency/bandwidth balance (imagine such a slider control in the Streamr Core UI). However, finding a good default value is important. From this analysis, we can conclude that:
  • The logarithmic behavior of network diameter leads us to hope that latency might behave logarithmically too, but since the number of hops is not the same as latency (in milliseconds), the scalability needs to be confirmed in the real world (see next section).
  • A node degree of 4 yields good latency/bandwidth balance, and we have selected this as the default value in the Streamr Network. This value is also used in all the real-world experiments described in the next section.
It’s worth noting that in such a network, the bandwidth requirement for publishers is determined by the node degree and not the number of subscribers. With a node degree 4 and a million subscribers, the publisher only uploads 4 copies of a data point, and the million subscribing nodes share the work of distributing the message among themselves. In contrast, a centralized data broker would need to push out a million copies.

Latency scales logarithmically

To see if actual latency scales logarithmically in real-world conditions, we ran large numbers of nodes in 16 different Amazon AWS data centers around the world. We ran experiments with network sizes between 32 to 2048 nodes. Each node published messages to the network, and we measured how long it took for the other nodes to get the message. The experiment was repeated 10 times for each network size.
The below image displays one of the key results of the paper. It shows a CDF (cumulative distribution function) of the measured latencies across all experiments. The y-axis runs from 0 to 1, i.e. 0% to 100%.
CDF of message propagation delay
From this graph we can easily read things like: in a 32 nodes network (blue line), 50% of message deliveries happened within 150 ms globally, and all messages were delivered in around 250 ms. In the largest network of 2048 nodes (pink line), 99% of deliveries happened within 362 ms globally.
To put these results in context, PubNub, a centralized message brokering service, promises to deliver messages within 250 ms — and that’s a centralized service! Decentralization comes with unquestionable benefits (no vendor lock-in, no trust required, network effects, etc.), but if such protocols are inferior in terms of performance or cost, they won’t get adopted. It’s pretty safe to say that the Streamr Network is on par with centralized services even when it comes to latency, which is usually the Achilles’ heel of P2P networks (think of how slow blockchains are!). And the Network will only get better with time.
Then we tackled the big question: does the latency behave logarithmically?
Mean message propagation delay in Amazon experiments
Above, the thick line is the average latency for each network size. From the graph, we can see that the latency grows logarithmically as the network size increases, which means excellent scalability.
The shaded area shows the difference between the best and worst average latencies in each repeat. Here we can see the element of chance at play; due to the randomness in which nodes become neighbours, some topologies are faster than others. Given enough repeats, some near-optimal topologies can be found. The difference between average topologies and the best topologies gives us a glimpse of how much room for optimisation there is, i.e. with a smarter-than-random topology construction, how much improvement is possible (while still staying in the realm of regular graphs)? Out of the observed topologies, the difference between the average and the best observed topology is between 5–13%, so not that much. Other subclasses of graphs, such as irregular graphs, trees, and so on, can of course unlock more room for improvement, but they are different beasts and come with their own disadvantages too.
It’s also worth asking: how much worse is the measured latency compared to the fastest possible latency, i.e. that of a direct connection? While having direct connections between a publisher and subscribers is definitely not scalable, secure, or often even feasible due to firewalls, NATs and such, it’s still worth asking what the latency penalty of peer-to-peer is.

Relative delay penalty in Amazon experiments
As you can see, this plot has the same shape as the previous one, but the y-axis is different. Here, we are showing the relative delay penalty (RDP). It’s the latency in the peer-to-peer network (shown in the previous plot), divided by the latency of a direct connection measured with the ping tool. So a direct connection equals an RDP value of 1, and the measured RDP in the peer-to-peer network is roughly between 2 and 3 in the observed topologies. It increases logarithmically with network size, just like absolute latency.
Again, given that latency is the Achilles’ heel of decentralized systems, that’s not bad at all. It shows that such a network delivers acceptable performance for the vast majority of use cases, only excluding the most latency-sensitive ones, such as online gaming or arbitrage trading. For most other use cases, it doesn’t matter whether it takes 25 or 75 milliseconds to deliver a data point.

Latency is predictable

It’s useful for a messaging system to have consistent and predictable latency. Imagine for example a smart traffic system, where cars can alert each other about dangers on the road. It would be pretty bad if, even minutes after publishing it, some cars still haven’t received the warning. However, such delays easily occur in peer-to-peer networks. Everyone in the crypto space has seen first-hand how plenty of Bitcoin or Ethereum nodes lag even minutes behind the latest chain state.
So we wanted to see whether it would be possible to estimate the latencies in the peer-to-peer network if the topology and the latencies between connected pairs of nodes are known. We applied Dijkstra’s algorithm to compute estimates for average latencies from the input topology data, and compared the estimates to the actual measured average latencies:
Mean message propagation delay in Amazon experiments
We can see that, at least in these experiments, the estimates seemed to provide a lower bound for the actual values, and the average estimation error was 3.5%. The measured value is higher than the estimated one because the estimation only considers network delays, while in reality there is also a little bit of a processing delay at each node.

Conclusion

The research has shown that the Streamr Network can be expected to deliver messages in roughly 150–350 milliseconds worldwide, even at a large scale with thousands of nodes subscribing to a stream. This is on par with centralized message brokers today, showing that the decentralized and peer-to-peer approach is a viable alternative for all but the most latency-sensitive applications.
It’s thrilling to think that by accepting a latency only 2–3 times longer than the latency of an unscalable and insecure direct connecion, applications can interconnect over an open fabric with global scalability, no single point of failure, no vendor lock-in, and no need to trust anyone — all that becomes available out of the box.
In the real-time data space, there are plenty of other aspects to explore, which we didn’t cover in this paper. For example, we did not measure throughput characteristics of network topologies. Different streams are independent, so clearly there’s scalability in the number of streams, and heavy streams can be partitioned, allowing each stream to scale too. Throughput is mainly limited, therefore, by the hardware and network connection used by the network nodes involved in a topology. Measuring the maximum throughput would basically be measuring the hardware as well as the performance of our implemented code. While interesting, this is not a high priority research target at this point in time. And thanks to the redundancy in the network, individual slow nodes do not slow down the whole topology; the data will arrive via faster nodes instead.
Also out of scope for this paper is analysing the costs of running such a network, including the OPEX for publishers and node operators. This is a topic of ongoing research, which we’re currently doing as part of designing the token incentive mechanisms of the Streamr Network, due to be implemented in a later milestone.
I hope that this blog has provided some insight into the fascinating results the team uncovered during this research. For a more in-depth look at the context of this work, and more detail about the research, we invite you to read the full paper.
If you have an interest in network performance and scalability from a developer or enterprise perspective, we will be hosting a talk about this research in the coming weeks, so keep an eye out for more details on the Streamr social media channels. In the meantime, feedback and comments are welcome. Please add a comment to this Reddit thread or email [[email protected]](mailto:[email protected]).

Chainlink is the most overvalued "cryptocurrency" the world has ever seen

There are 1,000,000,000 LINK tokens, which gives it a market cap of $3.2 billion.
If you remove Tether, that would place it #6 as the most valuable "cryptocurrency". If you remove XRP, which is also not a cryptocurrency, it would place it #5. If you merge bitcoin forks, it would be #3, right under Ethereum.
Its current position is #11 according to CoinMarketcap, but that's because 650,000,000 tokens are owned by the team. Those tokens are not locked, nor legally bound by any agreement to not be sold. In fact the team has already started dumping them. They are literally circulating by any technical or legal definition, but for some reason CoinMarketcap decides to mislead investors and say they are not circulating. (https://beincrypto.com/chainlink-team-accused-of-dumping-530-million-in-link-tokens-over-six-weeks/)
The team promises in its whitepaper that half those tokens will be "rewards for nodes", but why would you trust the team? They've lied countless times. For example when they plaster in their marketing everywhere that their oracles are decentralized (they are not), Vitalik himself says so. The only "consensus algorithm" they use is to KYC each node manually. (https://web.archive.org/web/20200416103509/https://www.reddit.com/LINKTradecomments/fyxc23/whats_up_with_vitalik_constantly_bashing/fn35ae0/)
They've also lied about many partnerships. For example, they've said several times that they work with Swift, which is not true. They won some Swift competition in 2016, and radio silence since then. They still claim to be working with Swift today, but they conveniently removed it from their website not long ago. (https://web.archive.org/web/20190820085402/https://chain.link/)
They also claim to be working with Google, which is also a lie. They did 1 blog post 1 year ago, which was basically a thinly veiled ad for Google Cloud services. It was provably neither a partnership nor integration. The Google employee never even ran a node on mainnet. Yet the team constantly boasts about "working with Google". (https://web.archive.org/web/20190820085402/https://chain.link/)
They did the same with Oracle Cloud. Fernando (the Oracle employee that organized the "partnership") bragged about holding LINK after it pumped, got demoted, and all the Oracle startups that were supposed to be part of the "partnership" turned out to be dead or fake companies. It was at best a PR stunt for Oracle Cloud, at worst insider trading by Oracle employees. (https://web.archive.org/web/20200114062507/https://twitter.com/fribeiro1/status/1213946909464973316)
Chainlink has dozens of other "partnerships". I don't have time to investigate all of them, but all the ones I looked into were basically fake. (And by fake I mean they are grossly exaggerated, the tweets and blogposts are real)
As of today, even though they are the highest valued non-bitcoin, non-ethereum cryptoccurency in the world, the only project using their centralized KYC oracles are Synthetix (according to someone from their team). (https://web.archive.org/web/20200416104122/https://www.reddit.com/Chainlink/comments/fdwaad/request_examples_of_apps_built_with_chainlink/fjkhsjv/)
They apparently have countless big name companies "that will use Chainlink soon", but considering their testnet has been usable for close to 2 years, they have 1-2+ years old "partnerships" that are still not using it, and that their MO is to lie as much as humanly possible, I doubt it's true.

During this technical world, bitcoin is the foremost used digital currency all over the world. However the main question then arises within the minds of the many folks is why bitcoin is considered the foremost superior over other cryptocurrenc Bitcoin Freedom
Bitcoin is that the one method of creating transactions daily as alternative currencies. But it's its options and uniqueness that make it superior. Bitcoin and different currencies are based mostly on the cryptographic algorithms or mathematics that are encrypted, with that the user becomes the owner of the currency. Bitcoin currencies are easily accessible at Bitcoin ATM and online exchange
The main feature of the bitcoin, which makes it superior is that it is the safest option for digital transactions. These will be used for on-line searching and transfer of money too.
There are many alternative blessings to using bitcoin. A number of them are mentioned below
Decentralized and digital
Bitcoin offers the freedom of exchanging the price without representatives that proves helpful in controlling the lower fees and high funds. Bitcoin is that the faster method of transaction than others. It is secure as it is free from theft and frauds and is constant. The main advantage is that bitcoin has its homeowners whereas the bank controls the money.
Makes online looking
Normally, bitcoin will be used for on-line shopping too. Bitcoin is the opposite face of e-wallet, that is created by blockchain technology that is used to store money and will easily pay everywhere digitally. For this reason, it also makes your searching easy by which you'll be able to look from your home solely

Bitcoin is accepted globally at each corner of the planet, which makes it less volatile than local currencies or cash. This feature makes it superior because it enables us to form transactions on-line and across the boundaries

Bitcoin is created by blockchain technology. Blockchain is the sole technology which will either make it or break it. There are many computers which are used to keep up a permanent record of each bitcoin transactions with the help of cryptographic technique. In this approach, it becomes a lot of valuable together with the tracking of the payment. At the same time, there's no method of tracking the cash

While not any transformation method, it will be used over the entire world. It provides the simplest platform for the investment as it is free from the restrictions of governments or banks. It provides an open market and combines the simplest of gold and money.

Bitcoin provides the power to access the balance of the users with a password which is named a personal key. It additionally permits the exchange of values through the web without any middle person. Thus, bitcoin becomes safer, stuffed with privacy, and open to everyone
Unlike cash, it is not possible to form the duplicate quite bitcoin that makes it more efficient. It's protected with the technology of blockchain. Even if anyone tries to form a replica of bitcoin to use it, then the system will automatically reject it as the system recognize it as unknown

Bitcoin Freedom failed to allow two persons to transact on the one price. Once the bitcoin is transferred, its possession is also transferred. So this is the simple approach of maintaining records for any tax functions. It conjointly makes it a easy and healthier metho

Zhuoer Jiang: Talk about the difference between BTC, BCH and BSV

Zhuoer Jiang: Talk about the difference between BTC, BCH and BSV

https://preview.redd.it/kcdq7qrjnyd51.jpg?width=570&format=pjpg&auto=webp&s=af67bd46683fbe3ffa6c081d490d69598dd83bbb
1. When do you contact Bitcoin? What do you think of the blockchain industry?
I came into contact with Bitcoin in October 2013. At that time, I was making game aids, which involved the issue of collecting money from Taiwan and Southeast Asia.
The reason for cultivating the blockchain industry is that blockchain is the only industry that can provide economic freedom. The blockchain is decentralized and has no control center, so no one can eliminate it, so it provides economic freedom. The counter-example is Qvod player. Although Qvod player also has tens of thousands of nodes, it is centralized. As long as the control center is killed, the Qvod player network will die. (QvodPlayer is a Chinese-based video-on-demand playback software, using P2P technology, users can watch online film and television programs through buffering. In mainland China, QvodPlayer has a huge number of users. Due to the use of a dedicated transmission protocol, QvodPlayer is used by some users to download banned videos, such as violent or pornographic videos, and politically sensitive videos. In addition, pirated movies are rampant in QvodPlayer)
I am not a Bitcoinist. As long as other tokens provide economic freedom, I will buy them with real money. My position portfolio is BCH 40% + BTC 30% + ETH 20% + economically free innovative currency 10%, and I think that ETH is likely to exceed BTC in total market value in this bull market.
2. What is the difference between BTC, BCH and BSV?
The easiest thing to see is the difference in block size. BTC blocks have been locked at about 1MB, while BSV advocates infinite blocks. BCH advocates a moderate block size, which cannot exceed the carrying capacity of an ordinary computer. The current value is about 32MB.
Both BTC and BSV have gone to extremes. The BTC development team, Core, pursues extreme decentralization, resulting in too small blocks and high transaction fees. In the last bull market, a transaction fee was as high as hundreds of thousands of yuan, which caused a large number of BTC users to flow out to BCH, ETH and other tokens.
Some people think that BTC can rely entirely on stored-value users instead of using users to survive. This is impossible. If there are no users, there are no stored value users. For example, gold is obviously more suitable for storing value, but almost everyone has bank deposits, except for the elderly, almost no one uses gold to store value. To
People usually use paper money to store value, and naturally they also use paper money to store value. It is impossible to use paper money to store value with gold, and it is impossible to use paper money for small transactions and gold for large transactions. Currency has a scale effect, and it must be a winner takes all.
BSV has gone to the other extreme. The blockchain is enough to store transaction data, but if the blockchain is used as cloud storage, no amount of space is enough. Think about how many resources the world has to store. The result is that the performance requirements are too high, the number of nodes is drastically reduced, and the foundation of the blockchain, which is decentralization, is lost. In the end, it falls into the same fate as the Qvod player. To
Behind the different block sizes are the differences in the spirit of the three. Just like during the Opium War, the difference between Britain and China's Qing Dynasty was not a superficial weapon, but a complete political, economic, and technological gap behind it.
Both BTC and BSV are irrational and religious to a certain extent. BTC advocates a deadlock block size, and BSV advocates a deadlock protocol. The two are very similar.
In terms of rational development and serving users, BCH has won. For example, the issuance of tokens is an important function and rigid demand of the blockchain. Tokens can already be issued on BCH through several protocols such as Wormhole and SLP, while BTC and BSV cannot yet. This is a huge difference in development.
3. Under what circumstances can BCH exceed BTC?
BCH has to wait for users to slowly develop until the number of users and transactions exceed BTC. Although under normal circumstances, the currency has a scale effect, this situation is unlikely to happen, but BTC made a fatal mistake, and locked the block and locked the user.
What if BTC expands like BCH?
First of all, BTC cannot be expanded because the expansion requires a hard fork, regardless of whether it is within the community or the Core, it must adhere to 1MB, insist on extreme decentralization, and BTC must be able to run on the Raspberry Pi. The result is that the expansion advocates in BTC and Core re-hard fork.
Isn't this the plot of the hard fork of BCH from BTC in 2017? So what are these "advocates" doing hard forking again? Just go straight to BCH.
Therefore, BTC must undergo a hard fork to expand, so it cannot be expanded.
So BCH only needs to catch up, which is a fixed goal. I estimate that in this bull market, BCH can exceed the number of users. At that time, BCH had a solid foundation of users and communities. The price increase only increases the price of BCH, the value of BCH is determined by the number of users, and the price fluctuates around the value.
4. Will BCH hard fork happen? What impact will it have on us later?
The BCH community has recently had a lot of discussions on the issue of miner donations, which reflects the decentralization of BCH.
If BCH is controlled by bitmain, why it took a long time for bitmain to implement this problem? Conversely, if CSW wants to modify something on BSV, it can be passed immediately.
5. Do you think BCH is worth long-term ownership?
I often say: "Ask God in the short term, and the number of users in the long term."
The longer the time, the more worth holding BCH. BCH is developing rapidly due to the correct route. I just gave an example. There are already several schemes for issuing tokens on BCH, but neither BTC nor BSV have one. Part of it is because BSV locks the protocol and is not convenient for development. The other part It is because the BSV community has inherited the characteristics of CSW and only speaks big words and does not do practical things.
Therefore, it is definitely worth holding for 1 to 2 years, and the rate of increase is likely to be higher than that of BTC. I predict that the highest point of this round of bull market for BCH will rise from about 3.6% of BTC to 10% to 20% of BTC.
8. Free Q&A
"Will Bitcoin die due to quantum computers or other reasons?"
Certainly not, at best, replace a quantum-resistant algorithm. Looking at it now, quantum computers will not be practical for a long time. And I think quantum computers may not be able to solve the NP problem, that is, the current asymmetric encryption problem, which may not be possible mathematically.
"The impact of the proliferation of contract transactions on currency prices?"
The currency price is ultimately determined by the number of users, not by speculative users. The proliferation of futures trading has happened long ago. From 2016 to 2017, in the presence of a large number of futures trading, BTC rose 100 times.
"Will you be notified when you escape?"
I will definitely not inform. I have already made predictions. I think the bull market may end in the second half of 2021. Or conversely, this bull market may last for two to three years, and two years are more likely.
Why not notify? Most of my clients are miners, and the currency price directly affects the income of the miners. If the currency price drops due to my notification, the interests of my clients will be damaged.
"Recommended regular investment in 2019, what strategy is recommended in 2020?"
This year's bull market has begun, and it must be a full position investment. The cost of regular investment to buy coins later is very high.
"Is it better to speculate or to mine now?"
Most people can't insist on holding the token from start to finish. Most people are in the middle of the bull market, or even sell it at the beginning, and then miss the entire bull market.
Only miners, no matter what level of miners, will hold the token from beginning to end. During the entire bull market, miners are very profitable. Miners will certainly not sell the goose that lays golden eggs like mining machines in the bull market, so miners tend to make more. The earliest miners are basically still active in the market, and their wealth is free, while the earliest holders of coins are almost gone.

ABSTRACT

In this research report, we present a study on Kyber Network. Kyber Network is a decentralized, on-chain liquidity protocol designed to make trading tokens simple, efficient, robust and secure.
Kyber design allows any party to contribute to an aggregated pool of liquidity within each blockchain while providing a single endpoint for takers to execute trades using the best rates available. We envision a connected liquidity network that facilitates seamless, decentralized cross-chain token swaps across Kyber based networks on different chains.
Kyber is a fully on-chain liquidity protocol that enables decentralized exchange of cryptocurrencies in any application. Liquidity providers (Reserves) are integrated into one single endpoint for takers and users. When a user requests a trade, the protocol will scan the entire network to find the reserve with the best price and take liquidity from that particular reserve.

1.INTRODUCTION

DeFi applications all need access to good liquidity sources, which is a critical component to provide good services. Currently, decentralized liquidity is comprised of various sources including DEXes (Uniswap, OasisDEX, Bancor), decentralized funds and other financial apps. The more scattered the sources, the harder it becomes for anyone to either find the best rate for their trade or to even find enough liquidity for their need.
Kyber is a blockchain-based liquidity protocol that aggregates liquidity from a wide range of reserves, powering instant and secure token exchange in any decentralized application.
The protocol allows for a wide range of implementation possibilities for liquidity providers, allowing a wide range of entities to contribute liquidity, including end users, decentralized exchanges and other decentralized protocols. On the taker side, end users, cryptocurrency wallets, and smart contracts are able to perform instant and trustless token trades at the best rates available amongst the sources.
The Kyber Network is project based on the Ethereum protocol that seeks to completely decentralize the exchange of crypto currencies and make exchange trustless by keeping everything on the blockchain.
Through the Kyber Network, users should be able to instantly convert or exchange any crypto currency.

1.1 OVERVIEW ABOUT KYBER NETWORK PROTOCOL

The Kyber Network is a decentralized way to exchange ETH and different ERC20 tokens instantly — no waiting and no registration needed.
Using this protocol, developers can build innovative payment flows and applications, including instant token swap services, ERC20 payments, and financial DApps — helping to build a world where any token is usable anywhere.
Kyber’s fully on-chain design allows for full transparency and verifiability in the matching engine, as well as seamless composability with DApps, not all of which are possible with off-chain or hybrid approaches. The integration of a large variety of liquidity providers also makes Kyber uniquely capable of supporting sophisticated schemes and catering to the needs of DeFi DApps and financial institutions. Hence, many developers leverage Kyber’s liquidity pool to build innovative financial applications, and not surprisingly, Kyber is the most used DeFi protocol in the world.
The Kyber Network is quite an established project that is trying to change the way we think of decentralised crypto currency exchange.
The Kyber Network has seen very rapid development. After being announced in May 2017 the testnet for the Kyber Network went live in August 2017. An ICO followed in September 2017, with the company raising 200,000 ETH valued at $60 million in just one day.
The live main net was released in February 2018 to whitelisted participants, and on March 19, 2018, the Kyber Network opened the main net as a public beta. Since then the network has seen increasing growth, with network volumes growing more than 500% in the first half of 2019.
Although there was a modest decrease in August 2019 that can be attributed to the price of ETH dropping by 50%, impacting the overall total volumes being traded and processed globally.
They are developing a decentralised exchange protocol that will allow developers to build payment flows and financial apps. This is indeed quite a competitive market as a number of other such protocols have been launched.
In Brief - Kyber Network is a tool that allows anyone to swap tokens instantly without having to use exchanges. - It allows vendors to accept different types of cryptocurrency while still being paid in their preferred crypto of choice. - It’s built primarily for Ethereum, but any smart-contract based blockchain can incorporate it.
At its core, Kyber is a decentralized way to exchange ETH and different ERC20 tokens instantly–no waiting and no registration needed. To do this Kyber uses a diverse set of liquidity pools, or pools of different crypto assets called “reserves” that any project can tap into or integrate with.
A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go.
All this swapping happens directly on the Ethereum blockchain, meaning every transaction is completely transparent.

1.1.1 WHY BUILD THE KYBER NETWORK?

While crypto currencies were built to be decentralized, many of the exchanges for trading crypto currencies have become centralized affairs. This has led to security vulnerabilities, with many exchanges becoming the victims of hacking and theft.
It has also led to increased fees and costs, and the centralized exchanges often come with slow transfer times as well. In some cases, wallets have been locked and users are unable to withdraw their coins.
Decentralized exchanges have popped up recently to address the flaws in the centralized exchanges, but they have their own flaws, most notably a lack of liquidity, and often times high costs to modify trades in their on-chain order books.

Some of the Integrations with Kyber Protocol
The Kyber Network was formed to provide users with a decentralized exchange that keeps everything right on the blockchain, and uses a reserve system rather than an order book to provide high liquidity at all times. This will allow for the exchange and transfer of any cryptocurrency, even cross exchanges, and costs will be kept at a minimum as well.
The Kyber Network has three guiding design philosophies since the start:
  1. To be most useful the network needs to be platform-agnostic, which allows any protocol or application the ability to take advantage of the liquidity provided by the Kyber Network without any impact on innovation.
  2. The network was designed to make real-world commerce and decentralized financial products not only possible but also feasible. It does this by allowing for instant token exchange across a wide range of tokens, and without any settlement risk.
  3. The Kyber Network was created with ease of integration as a priority, which is why everything runs fully on-chain and fully transparent. Kyber is not only developer-friendly, but is also compatible with a wide variety of systems.

1.1.2 WHO INVENTED KYBER?

Kyber’s founders are Loi Luu, Victor Tran, Yaron Velner — CEO, CTO, and advisor to the Kyber Network.

1.1.3 WHAT DISTINGUISHES KYBER?

Kyber’s mission has always been to integrate with other protocols so they’ve focused on being developer-friendly by providing architecture to allow anyone to incorporate the technology onto any smart-contract powered blockchain. As a result, a variety of different dapps, vendors, and wallets use Kyber’s infrastructure including Set Protocol, bZx, InstaDApp, and Coinbase wallet.
Besides, dapps, vendors, and wallets, Kyber also integrates with other exchanges such as Uniswap — sharing liquidity pools between the two protocols.
A typical use case would be if a vendor allowed customers to pay in whatever currency they wish, but receive the payment in their preferred token. Another example would be for Dapp users. At present, if you are not a token holder of a certain Dapp you can’t use it. With Kyber, you could use your existing tokens, instantly swap them for the Dapp specific token and away you go.
Limit orders on Kyber allow users to set a specific price in which they would like to exchange a token instead of accepting whatever price currently exists at the time of trading. However, unlike with other exchanges, users never lose custody of their crypto assets during limit orders on Kyber.
The Kyber protocol works by using pools of crypto funds called “reserves”, which currently support over 70 different ERC20 tokens. Reserves are essentially smart contracts with a pool of funds. Different parties with different prices and levels of funding control all reserves. Instead of using order books to match buyers and sellers to return the best price, the Kyber protocol looks at all the reserves and returns the best price among the different reserves. Reserves make money on the “spread” or differences between the buying and selling prices. The Kyber wants any token holder to easily convert one token to another with a minimum of fuss.

1.2 KYBER PROTOCOL

The protocol smart contracts offer a single interface for the best available token exchange rates to be taken from an aggregated liquidity pool across diverse sources. ● Aggregated liquidity pool. The protocol aggregates various liquidity sources into one liquidity pool, making it easy for takers to find the best rates offered with one function call. ● Diverse sources of liquidity. The protocol allows different types of liquidity sources to be plugged into. Liquidity providers may employ different strategies and different implementations to contribute liquidity to the protocol. ● Permissionless. The protocol is designed to be permissionless where any developer can set up various types of reserves, and any end user can contribute liquidity. Implementations need to take into consideration various security vectors, such as reserve spamming, but can be mitigated through a staking mechanism. We can expect implementations to be permissioned initially until the maintainers are confident about these considerations.
The core feature that the Kyber protocol facilitates is the token swap between taker and liquidity sources. The protocol aims to provide the following properties for token trades: ● Instant Settlement. Takers do not have to wait for their orders to be fulfilled, since trade matching and settlement occurs in a single blockchain transaction. This enables trades to be part of a series of actions happening in a single smart contract function. ● Atomicity. When takers make a trade request, their trade either gets fully executed, or is reverted. This “all or nothing” aspect means that takers are not exposed to the risk of partial trade execution. ● Public rate verification. Anyone can verify the rates that are being offered by reserves and have their trades instantly settled just by querying from the smart contracts. ● Ease of integration. Trustless and atomic token trades can be directly and easily integrated into other smart contracts, thereby enabling multiple trades to be performed in a smart contract function.
How each actor works is specified in Section Network Actors. 1. Takers refer to anyone who can directly call the smart contract functions to trade tokens, such as end-users, DApps, and wallets. 2. Reserves refer to anyone who wishes to provide liquidity. They have to implement the smart contract functions defined in the reserve interface in order to be registered and have their token pairs listed. 3. Registered reserves refer to those that will be cycled through for matching taker requests. 4. Maintainers refer to anyone who has permission to access the functions for the adding/removing of reserves and token pairs, such as a DAO or the team behind the protocol implementation. 5. In all, they comprise of the network, which refers to all the actors involved in any given implementation of the protocol.
The protocol implementation needs to have the following: 1. Functions for takers to check rates and execute the trades 2. Functions for the maintainers to registeremove reserves and token pairs 3. Reserve interface that defines the functions reserves needs to implement

1.3 KYBER CORE SMART CONTRACTS

Kyber Core smart contracts is an implementation of the protocol that has major protocol functions to allow actors to join and interact with the network. For example, the Kyber Core smart contracts provide functions for the listing and delisting of reserves and trading pairs by having clear interfaces for the reserves to comply to be able to register to the network and adding support for new trading pairs. In addition, the Kyber Core smart contracts also provide a function for takers to query the best rate among all the registered reserves, and perform the trades with the corresponding rate and reserve. A trading pair consists of a quote token and any other token that the reserve wishes to support. The quote token is the token that is either traded from or to for all trades. For example, the Ethereum implementation of the Kyber protocol uses Ether as the quote token.
In order to search for the best rate, all reserves supporting the requested token pair will be iterated through. Hence, the Kyber Core smart contracts need to have this search algorithm implemented.
The key functions implemented in the Kyber Core Smart Contracts are listed in Figure 2 below. We will visit and explain the implementation details and security considerations of each function in the Specification Section.

1.4 HOW KYBER’S ON-CHAIN PROTOCOL WORKS?

Kyber is the liquidity infrastructure for decentralized finance. Kyber aggregates liquidity from diverse sources into a pool, which provides the best rates for takers such as DApps, Wallets, DEXs, and End users.

1.4.1 PROVIDING LIQUIDITY AS A RESERVE

Anyone can operate a Kyber Reserve to market make for profit and make their tokens available for DApps in the ecosystem. Through an open reserve architecture, individuals, token teams and professional market makers can contribute token assets to Kyber’s liquidity pool and earn from the spread in every trade. These tokens become available at the best rates across DApps that tap into the network, making them instantly more liquid and useful.
MAIN RESERVE TYPES Kyber currently has over 45 reserves in its network providing liquidity. There are 3 main types of reserves that allow different liquidity contribution options to suit the unique needs of different providers. 1. Automated Price Reserves (APR) — Allows token teams and users with large token holdings to have an automated yet customized pricing system with low maintenance costs. Synthetix and Melon are examples of teams that run APRs. 2. Fed Price Reserves (FPR) — Operated by professional market makers that require custom and advanced pricing strategies tailored to their specific needs. Kyber alongside reserves such as OneBit, runs FPRs. 3. Bridge Reserves (BR) — These are specialized reserves meant to bring liquidity from other on-chain liquidity providers like Uniswap, Oasis, DutchX, and Bancor into the network.

1.5 KYBER NETWORK ROLES

There Kyber Network functions through coordination between several different roles and functions as explained below: - Users — This entity uses the Kyber Network to send and receive tokens. A user can be an individual, a merchant, and even a smart contract account. - Reserve Entities — This role is used to add liquidity to the platform through the dynamic reserve pool. Some reserve entities are internal to the Kyber Network, but others may be registered third parties. Reserve entities may be public if the public contributes to the reserves they hold, otherwise they are considered private. By allowing third parties as reserve entities the network adds diversity, which prevents monopolization and keeps exchange rates competitive. Allowing third party reserve entities also allows for the listing of less popular coins with lower volumes. - Reserve Contributors — Where reserve entities are classified as public, the reserve contributor is the entity providing reserve funds. Their incentive for doing so is a profit share from the reserve. - The Reserve Manager — Maintains the reserve, calculates exchange rates and enters them into the network. The reserve manager profits from exchange spreads set by them on their reserves. They can also benefit from increasing volume by accessing the entire Kyber Network. - The Kyber Network Operator — Currently the Kyber Network team is filling the role of the network operator, which has a function to adds/remove Reserve Entities as well as controlling the listing of tokens. Eventually, this role will revert to a proper decentralized governance.

1.6 BASIC TOKEN TRADE

A basic token trade is one that has the quote token as either the source or destination token of the trade request. The execution flow of a basic token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for ETH as an example. The trade happens in a single blockchain transaction. 1. Taker sends 1 ETH to the protocol contract, and would like to receive BAT in return. 2. Protocol contract queries the first reserve for its ETH to BAT exchange rate. 3. Reserve 1 offers an exchange rate of 1 ETH for 800 BAT. 4. Protocol contract queries the second reserve for its ETH to BAT exchange rate. 5. Reserve 2 offers an exchange rate of 1 ETH for 820 BAT. 6. This process goes on for the other reserves. After the iteration, reserve 2 is discovered to have offered the best ETH to BAT exchange rate. 7. Protocol contract sends 1 ETH to reserve 2. 8. The reserve sends 820 BAT to the taker.

1.7 TOKEN-TO-TOKEN TRADE

A token-to-token trade is one where the quote token is neither the source nor the destination token of the trade request. The exchange flow of a token to token trade is depicted in the diagram below, where a taker would like to exchange BAT tokens for DAI as an example. The trade happens in a single blockchain transaction. 1. Taker sends 50 BAT to the protocol contract, and would like to receive DAI in return. 2. Protocol contract sends 50 BAT to the reserve offering the best BAT to ETH rate. 3. Protocol contract receives 1 ETH in return. 4. Protocol contract sends 1 ETH to the reserve offering the best ETH to DAI rate. 5. Protocol contract receives 30 DAI in return. 6. Protocol contract sends 30 DAI to the user.

2.KYBER NETWORK CRYSTAL (KNC) TOKEN

Kyber Network Crystal (KNC) is an ERC-20 utility token and an integral part of Kyber Network.
KNC is the first deflationary staking token where staking rewards and token burns are generated from actual network usage and growth in DeFi.
The Kyber Network Crystal (KNC) is the backbone of the Kyber Network. It works to connect liquidity providers and those who need liquidity and serves three distinct purposes. The first of these is to collect transaction fees, and a portion of every fee collected is burned, which keeps KNC deflationary. Kyber Network Crystals (KNC), are named after the crystals in Star Wars used to power light sabers.
The KNC also ensures the smooth operation of the reserve system in the Kyber liquidity since entities must use third-party tokens to buy the KNC that pays for their operations in the network.
KNC allows token holders to play a critical role in determining the incentive system, building a wide base of stakeholders, and facilitating economic flow in the network. A small fee is charged each time a token exchange happens on the network, and KNC holders get to vote on this fee model and distribution, as well as other important decisions. Over time, as more trades are executed, additional fees will be generated for staking rewards and reserve rebates, while more KNC will be burned. - Participation rewards — KNC holders can stake KNC in the KyberDAO and vote on key parameters. Voters will earn staking rewards (in ETH) - Burning — Some of the network fees will be burned to reduce KNC supply permanently, providing long-term value accrual from decreasing supply. - Reserve incentives — KNC holders determine the portion of network fees that are used as rebates for selected liquidity providers (reserves) based on their volume performance.

Finally, the KNC token is the connection between the Kyber Network and the exchanges, wallets, and dApps that leverage the liquidity network. This is a virtuous system since entities are rewarded with referral fees for directing more users to the Kyber Network, which helps increase adoption for Kyber and for the entities using the Network.
And of course there will soon be a fourth and fifth uses for the KNC, which will be as a staking token used to generate passive income, as well as a governance token used to vote on key parameters of the network.
The Kyber Network Crystal (KNC) was released in a September 2017 ICO at a price around $1. There were 226,000,000 KNC minted for the ICO, with 61% sold to the public. The remaining 39% are controlled 50/50 by the company and the founders/advisors, with a 1 year lockup period and 2 year vesting period.
Currently, just over 180 million coins are in circulation, and the total supply has been reduced to 210.94 million after the company burned 1 millionth KNC token in May 2019 and then its second millionth KNC token just three months later.
That means that while it took 15 months to burn the first million KNC, it took just 10 weeks to burn the second million KNC. That shows how rapidly adoption has been growing recently for Kyber, with July 2019 USD trading volumes on the Kyber Network nearly reaching $60 million. This volume has continued growing, and on march 13, 2020 the network experienced its highest daily trading activity of $33.7 million in a 24-hour period.
Currently KNC is required by Reserve Managers to operate on the network, which ensures a minimum amount of demand for the token. Combined with future plans for burning coins, price is expected to maintain an upward bias, although it has suffered along with the broader market in 2018 and more recently during the summer of 2019.
It was unfortunate in 2020 that a beginning rally was cut short by the coronavirus pandemic, although the token has stabilized as of April 2020, and there are hopes the rally could resume in the summer of 2020.

2.1 HOW ARE KNC TOKENS PRODUCED?

The native token of Kyber is called Kyber Network Crystals (KNC). All reserves are required to pay fees in KNC for the right to manage reserves. The KNC collected as fees are either burned and taken out of the total supply or awarded to integrated dapps as an incentive to help them grow.

2.2 HOW DO YOU GET HOLD OF KNC TOKENS?

Kyber Swap can be used to buy ETH directly using a credit card, which can then be used to swap for KNC. Besides Kyber itself, exchanges such as Binance, Huobi, and OKex trade KNC.

2.3 WHAT CAN YOU DO WITH KYBER?

The most direct and basic function of Kyber is for instantly swapping tokens without registering an account, which anyone can do using an Etheruem wallet such as MetaMask. Users can also create their own reserves and contribute funds to a reserve, but that process is still fairly technical one–something Kyber is working on making easier for users in the future.

2.4 THE GOAL OF KYBER THE FUTURE

The goal of Kyber in the coming years is to solidify its position as a one-stop solution for powering liquidity and token swapping on Ethereum. Kyber plans on a major protocol upgrade called Katalyst, which will create new incentives and growth opportunities for all stakeholders in their ecosystem, especially KNC holders. The upgrade will mean more use cases for KNC including to use KNC to vote on governance decisions through a decentralized organization (DAO) called the KyberDAO.
With our upcoming Katalyst protocol upgrade and new KNC model, Kyber will provide even more benefits for stakeholders. For instance, reserves will no longer need to hold a KNC balance for fees, removing a major friction point, and there will be rebates for top performing reserves. KNC holders can also stake their KNC to participate in governance and receive rewards.

2.5 BUYING & STORING KNC

Those interested in buying KNC tokens can do so at a number of exchanges. Perhaps your best bet between the complete list is the likes of Coinbase Pro and Binance. The former is based in the USA whereas the latter is an offshore exchange.
The trading volume is well spread out at these exchanges, which means that the liquidity is not concentrated and dependent on any one exchange. You also have decent liquidity on each of the exchange books. For example, the Binance BTC / KNC books are wide and there is decent turnover. This means easier order execution.
KNC is an ERC20 token and can be stored in any wallet with ERC20 support, such as MyEtherWallet or MetaMask. One interesting alternative is the KyberSwap Android mobile app that was released in August 2019.
It allows for instant swapping of tokens and has support for over 70 different altcoins. It also allows users to set price alerts and limit orders and works as a full-featured Ethereum wallet.

2.6 KYBER KATALYST UPGRADE

Kyber has announced their intention to become the de facto liquidity layer for the Decentralized Finance space, aiming to have Kyber as the single on-chain endpoint used by the majority of liquidity providers and dApp developers. In order to achieve this goal the Kyber Network team is looking to create an open ecosystem that garners trust from the decentralized finance space. They believe this is the path that will lead the majority of projects, developers, and users to choose Kyber for liquidity needs. With that in mind they have recently announced the launch of a protocol upgrade to Kyber which is being called Katalyst.
The Katalyst upgrade will create a stronger ecosystem by creating strong alignments towards a common goal, while also strengthening the incentives for stakeholders to participate in the ecosystem.
The primary beneficiaries of the Katalyst upgrade will be the three major Kyber stakeholders: 1. Reserve managers who provide network liquidity; 2. dApps that connect takers to Kyber; 3. KNC holders.
These stakeholders can expect to see benefits as highlighted below: Reserve Managers will see two new benefits to providing liquidity for the network. The first of these benefits will be incentives for providing reserves. Once Katalyst is implemented part of the fees collected will go to the reserve managers as an incentive for providing liquidity.
This mechanism is similar to rebates in traditional finance, and is expected to drive the creation of additional reserves and market making, which in turn will lead to greater liquidity and platform reach.
Katalyst will also do away with the need for reserve managers to maintain a KNC balance for use as network fees. Instead fees will be automatically collected and used as incentives or burned as appropriate. This should remove a great deal of friction for reserves to connect with Kyber without affecting the competitive exchange rates that takers in the system enjoy. dApp Integrators will now be able to set their own spread, which will give them full control over their own business model. This means the current fee sharing program that shares 30% of the 0.25% fee with dApp developers will go away and developers will determine their own spread. It’s believed this will increase dApp development within Kyber as developers will now be in control of fees.
KNC Holders, often thought of as the core of the Kyber Network, will be able to take advantage of a new staking mechanism that will allow them to receive a portion of network fees by staking their KNC and participating in the KyberDAO.

2.7 COMING KYBERDAO

With the implementation of the Katalyst protocol the KNC holders will be put right at the heart of Kyber. Holders of KNC tokens will now have a critical role to play in determining the future economic flow of the network, including its incentive systems.
The primary way this will be achieved is through KyberDAO, a way in which on-chain and off-chain governance will align to streamline cooperation between the Kyber team, KNC holders, and market participants.
The Kyber Network team has identified 3 key areas of consideration for the KyberDAO: 1. Broad representation, transparent governance and network stability 2. Strong incentives for KNC holders to maintain their stake and be highly involved in governance 3. Maximizing participation with a wide range of options for voting delegation
Interaction between KNC Holders & Kyber
This means KNC holders have been empowered to determine the network fee and how to allocate the fees to ensure maximum network growth. KNC holders will now have three fee allocation options to vote on: - Voting Rewards: Immediate value creation. Holders who stake and participate in the KyberDAO get their share of the fees designated for rewards. - Burning: Long term value accrual. The decreasing supply of KNC will improve the token appreciation over time and benefit those who did not participate. - Reserve Incentives:Value creation via network growth. By rewarding Kyber reserve managers based on their performance, it helps to drive greater volume, value, and network fees.

2.8 TRANSPARENCY AND STABILITY

The design of the KyberDAO is meant to allow for the greatest network stability, as well as maximum transparency and the ability to quickly recover in emergency situations. Initally the Kyber team will remain as maintainers of the KyberDAO. The system is being developed to be as verifiable as possible, while still maintaining maximum transparency regarding the role of the maintainer in the DAO.
Part of this transparency means that all data and processes are stored on-chain if feasible. Voting regarding network fees and allocations will be done on-chain and will be immutable. In situations where on-chain storage or execution is not feasible there will be a set of off-chain governance processes developed to ensure all decisions are followed through on.

2.9 KNC STAKING AND DELEGATION

Staking will be a new addition and both staking and voting will be done in fixed periods of times called “epochs”. These epochs will be measured in Ethereum block times, and each KyberDAO epoch will last roughly 2 weeks.
This is a relatively rapid epoch and it is beneficial in that it gives more rapid DAO conclusion and decision-making, while also conferring faster reward distribution. On the downside it means there needs to be a new voting campaign every two weeks, which requires more frequent participation from KNC stakeholders, as well as more work from the Kyber team.
Delegation will be part of the protocol, allowing stakers to delegate their voting rights to third-party pools or other entities. The pools receiving the delegation rights will be free to determine their own fee structure and voting decisions. Because the pools will share in rewards, and because their voting decisions will be clearly visible on-chain, it is expected that they will continue to work to the benefit of the network.

3. TRADING

After the September 2017 ICO, KNC settled into a trading price that hovered around $1.00 (decreasing in BTC value) until December. The token has followed the trend of most other altcoins — rising in price through December and sharply declining toward the beginning of January 2018.
The KNC price fell throughout all of 2018 with one exception during April. From April 6th to April 28th, the price rose over 200 percent. This run-up coincided with a blog post outlining plans to bring Bitcoin to the Ethereum blockchain. Since then, however, the price has steadily fallen, currently resting on what looks like a $0.15 (~0.000045 BTC) floor.
With the number of partners using the Kyber Network, the price may rise as they begin to fully use the network. The development team has consistently hit the milestones they’ve set out to achieve, so make note of any release announcements on the horizon.

4. COMPETITION

The 0x project is the biggest competitor to Kyber Network. Both teams are attempting to enter the decentralized exchange market. The primary difference between the two is that Kyber performs the entire exchange process on-chain while 0x keeps the order book and matching off-chain.
As a crypto swap exchange, the platform also competes with ShapeShift and Changelly.

  5. FAQ

1. What is Energi

Energi is a self-funding (no ICO and no premine) cryptocurrency that has a purpose to become the world’s leading cryptocurrency with the unification of Smart Contracts, Governance and Self-funding Treasury to ensure longevity and enable rapid growth. You can read more about why we decided to self-fund and chose not to conduct an ICO here.
Energi provides a small allocation to Proof-of-Stake (PoS) rewards, takes a bulk of the coin issuance and gives it to its treasury and active Masternodes. Energi also allocates 10% on-going reward to the leadership of the Energi Backbone, which is significantly less compared to today’s ICOs’ rewarding their founders between 20–50% of the tokens distributed. Another trait that sets Energi apart from ICOs is they give an on-going 10% allocation through each block reward, rather than rewarding the founders up-front.

2. What are the Fundamentals of Energi?

  • Scalability
1 minute block times and a 2 megabyte block size limit provide Energi with a vast transaction capacity for regular on-chain transactions. This allows for plenty of space on the blockchain for extremely fast transactions with very low fees.
Energi features a powerful on-chain scaling solution with a system of incentivized full nodes called Energi Masternodes. A Masternode is a full node backed by 1,000 NRG collateral that provides level 2 scalability to the Energi Cryptocurrency. 40% of the emissions of Energi is allocated to Masternodes, providing an extremely strong incentive to grow the number of full nodes and scalability of the network.

  • Funding
A key feature of Energi is its powerful treasury system. Energi makes up to 40% of the emissions available to the treasury, to be utilized in a manner that provides maximum benefit.
Treasury allocation is decentralized, allowing for submitted proposals from anyone, to be voted on by Masternodes and paid out from the emissions.
Energi has a 14 day treasury cycle, allowing quick payments for proposal authors and contributors, as well as strategic responsiveness to effective proposals. Energi is guided by the principle that every dollar spent from its funding model should yield more than one dollar of value in return. Thanks to a 14 day treasury cycle, the Energi team is able to measure results and respond quickly to changes in strategy.

  • Governance
The Energi Treasury is a decentralized governance model designed with Masternodes as caretakers, with voting rights on how to best utilize treasury funding.
This governance model reduces risk by allowing participation from everyone who holds 1,000 NRG as a Masternode. In this way, the Energi community can work together on how to best build the strategic direction of Energi.

  • Inflation
Energi Cryptocurrency has a simple rate of inflation at 1 million coins per month with no maximum cap. This ensures consistency in funding allocation, Masternode rewards, and PoS rewards, making the economics of the cryptocurrency more understandable for everyone who chooses to participate in Energi.
No coin supply limit ensures that Energi is prepared for the long term, avoiding “bubble” economics caused by dramatic early inflation that in most coins only serves to benefit founders ahead of increased adoption.

  • Distribution
Energi conducted a fair launch on April 14, 2018 with no ICO and no premine. Prior to launch, the Energi team gave a specific time and date for the launch of its main net, which its vibrant community eagerly awaited, so that mining could begin fairly, again avoiding centralization among the coin founders (It's important to note that Energi has transitioned from Proof-of-Work consensus to a Proof-of-Stake consensus).
Energi Masternode payments were designed to begin at block 216000, which occurred on September 18, 2018, almost 160 days after launch. This ensured time to list Energi on exchanges, and to grow the community, encouraging fair and equitable distribution before the extremely powerful Masternode rewards began. It is all too common for Masternode coins to feature a premine, which has the effect of centralizing distribution among the founders and early adopters.
From 2018 to 2020, Energi distributed nearly 4 million coins to users who contributed to spreading awareness of the project with social media activities about Energi, such as tweets, follows, and subscriptions on all major social media platforms.

  • Decentralization
Decentralized governance with Masternodes helps to ensure everyone is able to participate in Energi and help guide the project to achieve the best results. The change to the requirement to run a Masternode, from 10 000 NRG to 1 000 NRG, has allowed more people to be involved and boosted decentralization for the whole project.

  • Long Term Vision
All of the above features seamlessly work together in concert, to ensure that Energi is prepared for the long term. Rather than try to closely find a niche in the market, Energi is prepared to adapt and overcome all challenges for many years to come. Energi’s use case is that of a traditional cryptocurrency, such as Bitcoin. However, Energi’s strategy is to excel by avoiding the pitfalls of previous projects, while further utilizing and improving upon the most powerful ideas in the cryptocurrency space.

3. Coin Specs

Ticker: NRG
Block time: 1 minute.
Hashing Algorithm: Dagger-Hashimoto (similar to Ethereum).
Masternode requirements: 1,000 Energi.
Treasury cycle: Every 14 days.
Approximately 1 million Energi will be released per month. The allocations can be observed easily as “10/10/40/40.”
10% will go to the Energi Backbone.
10% to the PoS participants
40% to Masternodes.
40% to the Treasury.
Thus, for every block, allocations are: 2.28 Energi to the Backbone, 2.28 Energi to the PoS participants, 9.14 Energi to the Treasury, and 9.14 Energi to Masternodes.
Since Treasury allocations are paid in two-week cycles, they are made in lump sums of approximately 184,000 Energi every 14 days.
In order to allow for widespread distribution of Energi before Masternode payments began, Masternode rewards were delayed until day 150. This was to allow the airdrop campaign to be completed and ensure a large amount of NRG is spread out through the community. Until that point, Masternode rewards were redirected to the Treasury. Thus for the first 5 months, the Treasury gained approximately 368,000 Energi every two weeks (about 800k Energi per month). The airdrop campaign was designed to release ~4 million Energi to the community.

OneSwap: An Upgraded Version of UniSwap! An Ace DEX in the DeFi Ecosystem

Powerful DeFi

DeFi, or decentralized finance, represents the hottest topic in the blockchain industry and Ethereum ecosystem this year. According to data from DeFi Market Cap, the total market value of the top 100 projects in the DeFi ecosystem has exceeded US$6.9 billion, a tenfold increase in just three months. DeFi, which rose to fame in 2019, eventually regains its popularity in 2020.
Judged from another perspective, there have been signs for its popularity overnight. At the beginning of 2019, all major exchanges announced that they would enter the DEX field to define the trading model of cryptocurrencies in a brand new way. As one of the three major parts of DeFi, DEX has grown steadily in the cryptocurrency market, and has become the best choice for blockchain entrepreneurs to seek long-term development as centralized exchanges are confined to a bottleneck. Even though research shows that DEX contributed less than 1% to the overall transaction volume last year, there have appeared hundreds of new DEX platforms in the market for the past year.
Driven by DeFi, the trading volume of DEX in 2020 will grow to nearly US$5.1 billion. That is six times as much as the figure in 2019, with an increase of US$1.5 billion in June alone. In particular, Uniswap, the star DEX in the DeFi ecosystem, has outperformed its counterparts by transaction volume, with a daily transaction volume of more than US$100 million.
UniSwap is a token transaction protocol on Ethereum. It is a set of contracts deployed to the Ethereum network. All transactions are carried out on the chain. Anyone can exchange and withdraw tokens in UniSwap without registration or identification. UniSwap adopts automated market making (AMM), so users can buy and sell orders quickly without pending orders; at the same time, users can freely list coins and create trading pairs on Uniswap, and even get a share of the transaction fee as liquidity providers for tokens.
Once launched, UniSwap has been favored by the community and project developers. The super coins that may generate profits 100 times the cost as well as its efficient, easy-to-use product experience have attracted a large number of users who used to struggle in centralized exchanges for a long time. UniSwap has become the most popular DEX platform overnight, and the slippage rate of its mainstream DeFi project is even far lower than the figure of the first-tier exchanges.

Hidden dangers under madness

No listing fees, no delisting risks, and no restrictions at all.
In June alone, more than a dozen of super coins that may generate profits 100 times or even 1,000 times costs have been listed on UniSwap. Yet under such prosperity, crisis is simmering. Among the numerous projects, both good and bad, the platform is full of swindlers deceiving many investors; in addition, in spite of UniSwap’s efficient trading, the automated market making (AMM) lacks support of order book. All purchases on UniSwap are subject to the prices set thereon only, which greatly confines user’s transaction demands; what’s worse, UniSwap does not issue its own value tokens, and UniSwap’s liquidity providers only get the income from the transaction fee, leaving themselves risking losses for market making under unilateral conditions.
In general, UniSwap has been successful temporarily compared to other DEX. However, as the DeFi ecosystem gradually moves toward a broader market, its defects will hinder liquidity providers from gaining profits and users from having their diverse transaction needs met.

Upgraded UniSwap

With the globalization of the DeFi ecosystem, a DEX that can undertake thousands of projects and offer an excellent trading experience is needed in the market. After conducting in-depth research on all DEX products in the DeFi ecosystem, the OneSwap team combined user needs and market trends to create a fully decentralized transaction protocol on smart contracts—OneSwap, as we know it.
On July 29, 2020, OneSwap was officially launched on its official website.
OneSwap is a fully decentralized exchange protocol on Ethereum, with permission-free token listing and automated market making.
(I)Combination of automated market making and limit order
Similar to UniSwap, OneSwap applies the automated market making (AMM). Users can establish liquidity pools without permission, and make markets through automated algorithms. Liquidity providers can provide liquidity reserves for promising tokens. OneSwap will exchange two ERC20 Tokens in the liquidity pool based on a constant product algorithm, and the commissions obtained will be distributed to liquidity providers. Unlike UniSwap, OneSwap supports liquidity mining simultaneously. Through liquidity mining on OneSwap, users provide liquidity for the transaction token pool. For example, to provide liquidity for the ETH-AMPL pool, the liquidity provider can deposit ETH and AMPL tokens in a certain proportion, and then, according to the rules of the platform, gain both tokens and transaction fees on OneSwap.
In addition, in order to meet the diverse transaction needs of users, OneSwap will support the order book while adopting the AMM.
OneSwap's order book will be matched on the chain, which is different from the off-chain matching and on-chain clearing modes of other platforms. Since there is no centralized off-chain order book, OneSwap allows users to separately place orders at multiple different front ends developed by various vendors, without suspending its services due to failure in any vendor’s server. Based on the order book, users will not be forced to trade at the price set by the platform but buy or sell orders at a fixed price by themselves. That will be more flexible.
(II) Permissionless token listing and trading pair creation
For a decentralized trading platform, its restrictions determine how much freedom it can offer.
Unlike most pseudo-DEXs, OneSwap supports permission-free token creation, listing, and transactions without any listing fees. Users can trade on OneSwap with all Tokens that meet the ERC20 standard. In the past, small and medium-sized entrepreneurial teams needed to pay a large amount of listing fees apart from expenses for daily operation and project promotion. That was risky for them as it might make them unable to survive due to lack of funds. Fortunately, OneSwap can meet their needs including token listing, storage, transaction, and market making.
(III)Product experience more similar to CEX
The product design and functions of DEX on the current market are relatively simple, yet the threshold for use is high. Considering that, OneSwap develops a feature-rich, and easy-to-use operation interface based on users’ trading habits. Related functions such as K-line, depth map, and transaction history can even be expected.
OneSwap refines and upgrades the advantages of major platforms on the basis of UniSwap, Curve, and Balancer, and combines the product design of the CEX platform to create a more powerful UniSwap. We are confident that OneSwap will bring fresh surprises to the DeFi ecosystem and community.

Booming Ethereum

In response to the DeFi rush and the Ethereum 2.0 beacon chain, Ethereum has maintained an upward trend for six consecutive days and the price has kept rising from US$200 to a new high of US$330.
Driven by Ethereum, the digital currency market has remained prosperous overall as the Bitcoin value broke US$11,000. Overnight, the crypto community has got rid of the March 12 nightmare, as if it had regained the bull market in 2017.

Price Discovery in Bitcoin exchange

About thirty days ago I shared a chart on Price Discovery in this sub. There was a lot of interest in it and I promised to explain in detail a Bitcoin price discovery algorithm.. I do so in this post.
*this text post is a slightly shorter version of what I wrote in my blog.

TL;DR

I applied price discovery algorithms to 5 Min OHLCV data from Bitmex and CME contracts and Bitstamp, Coinbase, HitBTC, Kraken, Poloniex, Binance, and OkEx BTCUSD/BTCUSDT markets from March 2016 to May 2020. Some exciting results I got was:

Introduction

Price discovery is the overall process of setting the price of an asset. Price discovery algorithms identify the leader exchanges whose traders define the price. Two approaches are most famous for use in Price Discovery. Gonzalo and Granger (1995) and Hasbrouck (1995). But they assume random walk, and a common efficient price. I do not feel comfortable assuming random walk and common efficient price in Bitcoin Markets. So I used this little know method by De Blasis (2019) for this analysis. This work assumes that "the fastest price to reflect new information releases a price signal to the other slower price series." I thought this was valid in our market. It uses Markov Chains to measure Price Discovery. Without going into the mathematical details the summary steps used was:
De Blasis (2019) names this number Price Leadership Share (PLS). High PLS indicates a large role in price discovery. As the sum of the numbers is 1, they can be looked at as a percentage contribution. I recommend reading the original paper if you are interested to know more about the mathematical detail.

Data

Andersen (2000) argues that 5 Minute window provides the best trade-off between getting enough data and avoiding noise. In one of the first work on Bitcoin's Price Discovery, Brandvold et al. 2015 had used 5M window. So I obtained 5M OHLCV data using the following sources:
Futures data are different from other data because multiple futures contract trades at the same time. I formed a single data from the multiple time series by selecting the nearest contract until it was three days from expiration. I used the next contract when the contract was three days from expiration. This approach was advocated by Booth et al ( 1999 )

Analysis

I can't embed the chart on reddit so open this https://warproxxx.github.io/static/price_discovery.html
In the figure above, each colored line shows the total influence the exchange had towards the discovery of Bitcoin Price on that day. Its axis is on the left. The black line shows a moving average of the bitcoin price at the close in Bitfinex for comparison. The chart was created by plotting the EMA of price and dominance with a smoothing factor of 0.1. This was done to eliminate the noise. Let's start looking from the beginning. We start with a slight Bitfinex dominance at the start. When the price starts going up, Bitfinex's influence does too. This was the time large Tether printing was attributed to the rise of price by many individuals. But Bitfinex's influence wanes down as the price starts rising (remember that the chart is an exponential moving average. Its a lagging indicator). Afterward, exchanges like Binance and Bitstamp increase their role, and there isn't any single leader in the run. So although Bitfinex may have been responsible for the initial pump trades on other exchanges were responsible for the later rally.
CME contracts were added to our analysis in February 2018. Initially, they don't have much influence. On a similar work Alexandar and Heck (2019) noted that initially CBOE contracts had more influence. CBOE later delisted Bitcoin futures so I couldn't get that data. Overall, Bitmex and CME contracts have been averaging around 50% of the role in price discovery. To make the dominance clear, look at this chart where I add Bitmex Futures and Perp contract's dominance figure to create a single dominance index. There bitmex leads 936 of the total 1334 days (Bitfinex leads 298 days and coinbase and binance get 64 and 6 days). That is a lot. One possible reason for this might be Bitmex's low trading fee. Bitmex has a very generous -0.025% maker fee and price discovery tend to occur primarily in the market with smaller trading costs (Booth et al, 1999). It may also be because our market is mature. In mature markets, futures lead the price discovery.

Days Lead 571 501 102 88 34 12 8 7 6 4 1
 Table 1: Days Lead 
Out of 1334 days in the analysis, Bitmex futures leads the discovery in 571 days or nearly 43% of the duration. Bitfinex leads for 501 days. Bitfinex's high number is due to its extreme dominance in the early days.

 Table 2: Correlation between the close price and Exchange's dominance index 
Binance, Huobi, CME, and OkCoin had the most significant correlation with the close price. Bitmex, Coinbase, Bitfinex, and Bitstamp's dominance were negatively correlated. This was very interesting. To know more, I captured a yearwise correlation.

12 okex NaN NaN -0.618888 -0.399567 0.432474
Table 3: Yearwise Correlation between the close price and Exchange's dominance index
Price movement is pretty complicated. If one factor, like a dominant exchange, could explain it, everyone would be making money trading. With this disclaimer out of the way, let us try to make some conclusions. This year Bitfinex, Huobi, and OkEx, Tether based exchanges, discovery power have shown a high correlation with the close price. This means that when the traders there become successful, price rises. When the traders there are failing, Bitmex traders dominate and then the price is falling. I found this interesting as I have been seeing the OkEx whale who has been preceding price rises in this sub. I leave the interpretation of other past years to the reader.

Limitations

My analysis does not include market data for other derivative exchanges like Huobi, OkEx, Binance, and Deribit. So, all future market's influence may be going to Bitmex. I did not add their data because they started having an impact recently. A more fair assessment may be to conclude this as the new power of derivative markets instead of attributing it as the power of Bitmex. But Bitmex has dominated futures volume most of the time (until recently). And they brought the concept of perpetual swaps.

Conclusion

There is a lot in this data. If you are making a trading algo think there is some edge here. Someday I will backtest some trading logic based on this data. Then I will have more info and might write more. But, this analysis was enough for to shift my focus from a Bitfinex based trading algorithm to a Bitmex based one. It has been giving me good results.
If you have any good ideas that you want me to write about or discuss further please comment. If there is enough interest in this measurement, I can setup a live interface that provides the live value.
