Dragonchain Public Proposal TL;DR:Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.
Hello Reddit and Ethereum community!I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.
Executive summaryDragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.
Response and PoCIn The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.
A live proof of concept showing hundreds of thousands of transactionsOn Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.

24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.
How it works & scales
Architectural ScalingDragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.
Economic ScalingAn interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.
Scaled DeploymentDragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.
Flexibility in ScalingDragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table
How to run itBuilding on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
ArchitectureDragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.
APIs (on chain & off)
Known issues or tradeoffs
Costs and resources
Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.
This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum
Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to considerDragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
Usability Scaling solutions should have a simple end user experience.
Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactionsDragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.
Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees
Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
Users should be able to view their balances & transactions via a blockchain explorer-style interfaceFrom interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.
Exiting is fast & simpleWithdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.
Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.
Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
Documentation should be clear and completeFor full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.
Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.
Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!
TIMECommunity points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.
Dragon DenDragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.
Security. Users have full ownership & control of their points.All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.
Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone elseUsers can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.
Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone elseThrough our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw
Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offlineIf necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.
A public, third-party review attesting to the soundness of the design should be availableTo our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.
Bonus pointsSee above
Compatibility with HSMs & hardware walletsFor the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.
Minting/distributing tokens is not performed by Reddit directlyThis operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.
One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalableThis is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).
Fully open-source solutions are strongly preferredDragonchain is fully open source (see section on Disney release after conclusion).
ConclusionWhether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!
Disney Releases Blockchain Platform as Open SourceThe team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
Open SourceIn 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

If you are not bullish in general on cryptocurrencies you have no place in investing or trading cryptocurrencies since it's always a losing proposition to trade in bubbles, a scientifically proven fact. If on the other hand you are then your goal is to grow your portfolio more than you would if holding BTC/ETH for example.

Greetings from MCS, the derivatives trading platform where traders ALWAYS come first.
- This post has been written by HedgeTech
HedgeTech is an algorithmic crypto market maker for digital assets worldwide, with offices in Boston and Singapore. HedgeTech acts as designated market makers for token issuers and cryptocurrency exchanges. It also acts as technology providers for other market makers and broker-dealers.
As the cryptocurrency industry evolves, market makers are continuing to play a pertinent role on the markets. Crypto traders are no longer being fooled by unreliable metrics such as daily traded volume — often manipulated — and data reporting sites such as CoinGecko and Coinmarketcap now display more relevant numbers having to do with spread and liquidity — harder to fake. As a result, exchanges seek true orderbook depth and have developed many strategies to get market makers on board.
On the one hand, platforms incentivize traders and institutions to place maker orders by lowering the trading fees or sometimes offering rewards to market makers like HitBTC does with its “market making contracts”. Most of the market makers that fall under this category are profit driven market makers (PDMM).
On the other hand, and in addition to the aforementioned, exchanges such as Liquid require token issuers to have at least one designated market maker, sometimes even more, like Binance asking for 3 as a prerequisite to listing. Such market makers are called designated market makers (DMM).
PDMM and DMM differ in a number of ways, the most important one being their main motive. In this article, we will explore both types of market making and analyze who they serve.
Table 1. Key differences between Profit Driven and Designated Market Makers.
Profit Driven Market MakersPDMM are either individuals or institutions who seek to profit from a market making strategy and typically trade with their own capital. Simply put, PDMM will place a maker order on one side of the market and flip it to the other side when that order got filled. For every pair of orders being filled, PDMM will pocket net profits.
Profits per pair of order = average volume of the orders of the pair x difference in price between the two orders of the pair
The levels at which PDMM’s orders are placed depend on the behavior of the market.
In a sideways (stable fluctuations) pattern, PDMM will usually place their orders within the existing orderbook spread in price.
Figure 1. Example of a PDMM strategy on a market with sideways fluctuations
In a trendy pattern, say downtrend, a PDMM sell order will only attempt to be the best sell orders (i.e. at the lowest price possible) but their buy order will not be the best buy order so that they can ride the trend.
Figure 2. Example of a PDMM strategy on a market with downtrend
Regardless of the behavior of the market, two key factors impact how profitable PDMM are.
Overall profits = average difference in price between the two orders of pairs x average filling frequency for pairs of orders
The first important factor is the difference in price between orders in each pair of order, the larger the better. The difference in price determines the profits per pair of transaction. As a result, PDMM will enter a market voluntarily after carefully analyzing which markets offer the best spread opportunities.
The second factor playing a role in the profits generated is the frequency at which orders are filled, the higher the better. Indeed, a high frequency will result in a great number of pairs of orders being filled and thus more transactions to profit from. As a result, PDMM look for markets that are already actively traded.
Although PDMM place maker orders — thus contributing a bit to the market depth — and that such orders participate in closing the orderbook spread — especially when several PDMM compete — their main objective is to realize profits, not to improve market efficiency. Hence, PDMM are suitable for high net worth individuals or institutions willing to get their assets managed for profits.
In the digital assets industry, PDMM are typically crypto traders and private asset management funds. Finding PDMM that openly advertise as such is harder in such a young industry. That said, Cryptohopper for example is a software company that provides market making strategies, among others, destined to realize profits. If we had to draw a parallel with the older traditional markets, Jane Street for instance is known to use market making strategies, especially on ETFs, to generate significant returns for their investors.
Designated Market MakersDMM are institutions who are committed to improving markets efficiency and typically trade with their clients’ capital. The method used is quite unique in that DMM maintain orders on both the buy and the sell side at all times and in a systematic fashion. In other words, when an order is filled, say on the buy side, the DMM will immediately replace that order with an order of the sell side at the best price possible (i.e. the lowest price on the sell side).
In doing so, DMM maintain two key factors that impact all the other traders in the market.
First, DMM have the obligation to narrow the order book spread — i.e. the difference in price between the best buy and best sell. This guarantees that traders face the best price possible at all times.
Second, DMM ensure that the order book is filled with orders at different price levels — to allow the price to move according to supply and demand — and in a dense way — i.e. orders are close to one another. As a result, all other traders can simply take the DMM maker orders to enter or exit the market whenever they decide to do so, instantaneously. This second key factor is called market liquidity — or depth -, it guarantees that traders can trade at fair prices — close to market price — in combination with spread, and in desired quantities — i.e. with little to no slippage.
Combining both a narrow spread and a high liquidity additionally makes a market less volatile in price execution, yet not compromising price movement.
Figure 3. Without DMM: low liquidity, low density of orders, fragile spread; high slippage, high volatility, low efficiency.
Figure 4. With DMM: high liquidity, high density of orders, narrow spread; low slippage, low volatility, high efficiency.
It seems that DMM are hired to trade on less liquid markets.
Although DMM are committed to improving market efficiency, it does not mean that they do not make profits on their clients’ behalf. DMM strategies are designed in a way that ensures no losses to trading fees and profits when the price fluctuates, much like PDMM strategies on sideways markets. On top of that, DMM can also hedge their clients’ risk fully when on trendy market environments using orderbook replication strategies or derivatives products when available. Hence DMM are suitable for token issuers and exchanges willing to further improve their markets and better position themselves in a hyper competitive industry.
In crypto, DMM typically communicate more openly about their operations. Such institutions include GSR or HedgeTech for instance (for a more exhaustive list, you can refer to this article). This type of market making exists in traditional markets too as Johannes A Skjeltorp analyzed in his reseach paper .
ConclusionBoth PDMM and DMM are valuable participants of the crypto markets, much like any other market. That said, they serve two different purposes. On the one hand, PDMM work towards profitability and are hired to do so in their clients’ interests only. On the other hand, DMM work towards market efficiency for their clients’ markets. They are the last link of a long chain that went from blockchain to smart contracts, wallets, exchanges and finally orderbook to provide traders with the best environment possible.

Hello,submitted by spartanz51 to CryptoCurrency [link] [comments]
I got contacted by a friend that deposited money to the unknown exchange "ExtStock" He saw that exchange on Coinmarketcap and others website, pretending having best volume and liquidity.
ExtStock is announing fake volume, and Bitcoin price is 500-600$ higher than others platform.
The situation is that since some weeks, every users has theirs funds locked in the exchange. The support is talking about a "suspect activity", then no answer. They are just buying time.
I suspect them running a fractional reserve, probably because of a hack, an exit scam, or a bad investment with their customers funds?
But the fact is that they have locked funds and are still tweeting like if everything is normal.
I twitted about the situation to warm users about the exchange: https://twitter.com/anth0mk/status/1255923160643403776 but ExtStock blocked me.
I contacted some projects and platform to stop them supporting Extstock, like the LISK project.
The compagny behind Extstock is "EXCHANGE CLOUD LIMITED" a dormant UK compagny with 1$ as assets
Please, beware of platforms listed on Coinmarketcap, and others website: a lot of website are paid to list ExtStock between Kraken, coinbase and binance...

"You can literally access it from a public URL in the Web browser. There is no login or anything required, just type in the name of the merchant." (source)As of yet it is unclear if this is intentional by TBB or if Hayden Ottos followed the rules of responsible disclosure before publishing this kind of data leak.

CoinMarketCap just release a blog post announcing that they have listed a new metric on their website. They call this metric "Liquidity".submitted by UnknownEssence to CryptoCurrency [link] [comments]
The Liquidity metric by CoinMarketCap is designed to eventually replace volume as the default metric when ranking market pairs and exchanges.
We refrain from using a static percentage depth to calculate Liquidity, [...]You can see the Liquidity metric on CoinMarketCap's site now, when you view the exchanges for an asset.
Everyone knows that exchanges fake their volume numbers so they can appear at the top of this list. The new Liquidity metric is supposed to solve this problem. When filtering by the Liquidity, you should see a list of the actual most popular exchanges.
However, it seems this metric is still somewhat flawed. Even when filtering by "Liquidity", the list of exchanges is now what you would expect. Some of the most popular exchanges such as Binance are not even listed. Surely Binance has more liquidity than many of the exchanges listed here, and fake exchanges such as ZB.COM is listed as the 4th most liquid exchange. Has anybody every even used this exchange before?
What do you guys think of this new metric?

The Crypto Community Showed Mixed Signals About One Of The Largest M&A Deals In The Crypto Sector
Despite the ongoing COVID-19 virus outbreak, the world of crypto mergers and acquisitions (M&A) saw one of its biggest hits. In essence, Binance announced a 400 million dollar M&A deal with the leader of crypto data derivation CoinMarketCap.
Just days after the acquisition, the crypto sector reacted in a very diverse manner. Some crypto experts consider the recent acquisition as “hard for CoinMarketCap to remain neutral, with the latest moves by Binance.”
CoinGecko’s CEO Bobby Ong discussed the recent M&A deal on crypto blog MyTwoGwei. Ong stated that “such a large deal would impact the data integrity of CoinMarketCap. Furthermore, many new exchanges are faking their trading volumes to get ahead of the competition”.
CoinMarketCap had issues with data correctness, as Bitwise Asset Management reported at least 95% of the trading volumes, reported by crypto exchanges, are fake.
Both CoinMarketCap and CoinGecko developed data integrity tools to provide “realistic” trading volumes data, but now Ong claims his company remains the most significant “independent data aggregator.” CoinGecko even published a book covering the DeFi sector.
However, the broader crypto community welcomes the merge, as Changelly’s CEO Eric Benz stated that the timing is ideal for such a deal. Benz was joined by Mike Alfred, co-founder, and CEO of Digital Assets Data. Alfred commented that Binance sits among the top crypto companies in the world.
Despite Ong claiming his website as the top data aggregation software, his opinion is questionable, as platforms like Cryptobrowser.io combine API data aggregation for 1000+ cryptocurrencies with daily news and market recaps. Cryptobrowser.io also grants users with access to various ICO/STO/IEO data, exchanges data, as well as access to a list of the world’s most prominent crypto funds.

If you are following our posts, then you remember that we’ve discussed the disadvantages of both centralized and decentralized exchanges.submitted by 2Ether to u/2Ether [link] [comments]
As we’ve seen, platforms like Binance are black boxes — and they have control over your money. On the other hand, they are very fast and let you trade any currency pairs, no matter what blockchain each coin is built on. So you can trade ETH for BTC, for example. On a true decentralized exchange, this is very hard to do — yet. This is what’s called interoperability — the ability of different blockchains to talk to each other. Many of the best teams in crypto are working on this problem. In our upcoming posts, we’ll tell you all about those efforts — and how we plan to use them on 2Ether.
But let’s focus on the advantages of DEXes in general and our own 2EtherDEX in particular. Why do traders choose a decentralized exchange over Binance, for example:
There are two main reasons.
When you trade on a DEX, your crypto is always under your control. You don’t have to entrust it to the exchange. All that 2EtherDEX does is provide you with an interface and a way to find other users who can fill your order.
When you link your wallet to 2EtherDEX, you don’t give your private key to the system. None of your sensitive info will be stored on the server of the exchange. Even if hackers get access to the database of 2EtherDEX, they won’t be able to steal your assets.
Does this mean that your crypto is 100% safe? Unfortunately, you are never completely safe — so you have to exercise caution at all times. If you don’t use centralized exchanges, the only way a hacker can steal your crypto is by phishing — tricking you into providing your personal key. For example, a hacker could create a fake website that mirrors the real DEX, and convince you to enter the key there.
2) Easy listing
You’ve probably read that Poloniex, Kraken and others charge a huge amount of money to list new coins. They do have serious evaluation procedures, but it’s almost impossible to get on those exchanges without paying. The fee can reach $1 million and more. This means that only the richest projects can afford such listings.
Projects with smaller budgets have to deal with minor exchanges, but even they tend to charge exorbitant prices. The result is that many promising projects simply can’t afford a listing anywhere.
Do DEXes charge fees? Most of them do, but they are nowhere near as high as on centralized exchanges. This creates a more democratic air around DEXes. This gives talented team a way to get their token to the public even if their budget is modest.
Still, most DEXes charge at least something, and it makes sense. If you let people list their tokens for free, your exchange will be soon flooded with low-quality coins that nobody will want to trade.
On 2EtherDEX, we will charge a small fee of $300 for the listing. This isn’t much compared to what is charged by such large DEXes as CryptoBridge, for example, whose fee is several BTC.
Not every project is worthy of being listed, even if it has the money to pay the fee. For this reason, we’ll have a serious community evaluation procedure in place to select the best teams. Next time we’ll tell you all about it!
