Is Loopring A Decentralised Exchange?
Loopring is not a DEX, but a modular protocol for building DEXs on multiple blockchains. We disassemble the component parts of a traditional exchange and offer a set of public smart contracts and decentralized actors in its place. The roles in the network include wallets, relays, liquidity-sharing consortium blockchains, order book browsers, Ring-Miners, and asset tokenization services.
Order Rings are the heart of trading on Loopring. It uses something called a unidirection order model. Rather than filling or partially filling the buy and sell orders on the platform, it mixes and matches multiple order on the platform. Since every order is just a exchange rate between two tokens and order rings can include up to 16 different trades in a singe order ring, there should be better liquidity than there is on most certralised exchanges
This shows how Order Rings can take three different buy / sell orders and create a circular trade that fills all orders. Another interesting consequence of these types of trades is that it doesn’t require an equivalent trading pair. Trading pairs can still be executed, but these Order Ring are a unique way that Loopring can improve on liquidity.
“An order-ring is valid when all component transactions can be executed at an exchange rate equal to or better than the original rate specified implicitly by the user. To verify order-ring validity, Loopring protocol smart contracts must receive order-rings from ring-miners where the product of the original exchange rates of all orders is equal to or greater than 1.” - Whitepaper
This is a mathematical way of expressing the idea that no one can buy tokens for less than someone else is willing to sell them. If the exchange rate (ratio) is less than 1, this can’t logically be the case.
Relays are nodes that receive orders from wallets and the underlying liquidity building relay mesh. They use this information to maintain public order books, trade history, and broadcast orders to other relay nodes. Ring mining is a feature not a requirement of relays. Ring mining is done completely off-chain, and it is a computational heavy process. Relays are free in how they choose to communicate with one another, how they build their order books, and how they mine order-rings (mining algorithms).
I just want to reiterate at this point that Loopring is more of a tool kit for building decentralised exchanges than it is a decentralised exchange Different exchanges built on the platform are free to choose how consensus is reached and what mining algorithms are used.
Smart Contracts and Asset Tokenization Services
LPSC are A set of public and free smart contracts that checks the order-rings prepared by the ring-miners. Like other smart contracts their purpose is to automate and automatically settle and transfers tokens without user intervention. Actions built into smart contracts can incentivizes ring-miners and wallets with fee and keep order books up to date.
“The Loopring Smart Contracts do not perform exchange rate or amount calculations, but must receive and verify what the ring-miners supply for these values. These calculations are done by ring-miners for two main reasons: the programming language for smart contracts, such as solidity on Ethereum, does not have support for floating point math, especially pow(x, 1/n) (calculating the n-th root of a floating point number), and (2) it is desirable for the computation to be made off-chain to reduce blockchain computation and cost.” The whitepaper.
There are always going to be assets that can’t be traded on Loopring. To integrate these assets with the ecosystem the Asset Tokenizations Services (ATS) act as bridges between assets that cannot be directly traded on Loopring. Users can deposit assets and redeem them for tokens that are tradeable on Loopring.
“Loopring is not a cross-chain exchange protocol (until a suitable solution exists), but ATS enable trading of ERC20 tokens with physical assets as well as assets on other blockchains.”
Should I Invest In Loopring?
I think that along with Kyber Network and OmiseGo, Loopring is one of the most likely solutions for decentralised asset exchange and building interoperability between the various blockchains and ecosystems in the space.
The LRC token has consistent daily trading volumes around 10 million USD. It is a top 50 altcoin that's held its value better than most altcoins in the current bear market. It is listed on popular exchanges like Bittrex and Binance. There is an active community, on Reddit and Telegraph, and the team and founder Daniel Wang host frequent AMA sessions. A lot of hype and news worthy events around this cryptocurrency are generated from partnerships with different cryptocurrencies. The team has proven their ability time and time again to from these partnerships. This is a long term hold. What Loopring are trying to do will take years to reach mass adoption. Short term, we have speculative pumps to look forward to.
Loopring is a Chinese cryptocurrency lead by founder Daniel Wang. According to his LinkedIn page, he has previous experience with cryptocurrencies. In March of 2014, he founded a company called Coinport. They offer a bitcoin payment processor that is very popular in China. Prior to this he was worked for a company called JD.com as a high-level engineer.
