Loopring is a decentralized exchange protocol and an “automated execution system” built on Ethereum that will allow its users to trade assets across exchanges. It isn’t a decentralized exchange. Rather, it facilitates decentralized exchanging through ring-sharing and order matching. Decentralized and centralized exchanges alike will be able to implement Loopring, giving the exchanges access to cross blockchain and cross exchange liquidity and giving investors access to the best prices available on the broader market. Moreover, Loopring is blockchain agnostic, meaning that any platform that uses smart contracts (e.g., NEO, Ethereum, Qtum) can integrate with Loopring. Serving as its head, Loopring founder Daniel Wang used to run a centralized exchange called Coin Port back in 2014. “At that time,” he told Coin Central in an interview, “[I was] trying to solve the problems of centralized exchanges, and then I realized that it’s not possible. Those problems are inherent to the centralized exchange model.” Thus, he began conceptualizing what would become Loopring. In the past, he’s also held a position as a Google Tech Lead and was a co-founder and VP of Yunrang Technology. Loopring’s CMO, Jay Zhou, was formerly employed by Ernst and Young, helped found SJ Consulting, and used to work in PayPal’s Risk Operations unit. Johnston Chen, the project’s COO, has worked as the chief information officer at 3NOD. 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. Before defining each, we should first understand Loopring orders. At its root, the Loopring protocol is a social protocol in the sense that it relies on coordination amongst members to operate effectively towards a goal. This is not dissimilar to cryptoeconomic protocols at large, and indeed, its usefulness is largely protected by the same mechanisms of coordination problems [20], grim trigger equilibrium, and bounded rationality. The Loopring Protocol can facilitate trading between ERC20 tokens. Loopr needs to convert Ether to Ether Token for trading as Ether is not ERC20 compatible, but Ether Token is. Converting between Ether and Ether Token will be done for you automatically when you submit an order, but if you want to trade frequently, we strongly suggest you to convert some Ether to Ether Token beforehand manually; otherwise each order will take one more blockchain transaction just for the ETH-WETH conversion which takes time and gas. Conversions between ETH and WETH are done on-chain through Ethereum transactions. ETH and WETH are always converted 1:1 which is guaranteed by the WETH smart contract. The WETH smart contract also guarantees the total WETH issued is exactly the total ETH deposited. In other words, ETH and WETH is equiviate in value, and WETH is just the ERC20 form of ETH. The Loopring blockchain project had managed to raise almost 15 million US dollars during the period of the Loopring ICO, as all the regulatory experts watched this unprecedented crowdfunding. Daniel Wang, the founder and the main person behind the Loopring ICO, hand made it very transparent that the interface is quite bad but the underlying mechanism and the Order matching facility is very great. Loopring mining can be initiated very easily by using various performance calculating devices such as CPU, GPU, as well as application specific integrated circuits. The Loopring mining process can be initiated through the high-end Linux systems, according to reports. Loopring mining is basically a metaphor which is not similar to the Bitcoin mining but here the users need to match the specific orders from a huge database. Specifically, Loopring mining requires the usage of the ethereum nodes along with JSON API, IPFS, etc. Check out CoinBureau for the full review of Loopring.
Nuls (NULS) is a Singaporean based project is trying to develop a highly adaptable blockchain that can be used for enterprise solutions. They have regularly used the phrase “Nuls is nothing, Nuls is everything”. In other words, Nuls is not traditionally defined and can be melded into anything that the community sees fit. Nuls is looking to solve the problems faced by blockchains by creating one that features modularity and sub-chain operability. The two part design of functional modules and microkernels will provide both an underlying network mechanism and compartmentalized features for the blockchain.Essentially this should provide scalability and security to the blockchain, while adhering to the programming practices of low coupling and high cohesion. And because the blockchain is designed to be modular, it becomes hot pluggable, allowing for the addition or removal of modules at any time. There are several blockchain problems inhibiting growth and development of the industry that have been identified by the Nuls team. One such issue is the cost of development. Because there is a shortage of blockchain proficient developers, those with skills can command higher salaries.This is simply demand exceeding supply and will eventually level out as more IT professionals learn blockchain skills. That’s when businesses will see greater adoption of the technology, and only the most trustworthy blockchains will be of interest. Nuls is working to make trustworthy solutions to business problems. Nuls is primarily focused on making blockchain more accessible for developers and businesses. It seeks to do this through its modularity and the use of sub-chains, and hopes to break the complexity associated with blockchain projects, while also solving the scalability issue that is hindering the growth of the industry. Nuls will make trust simpler, increasing the adoption rate of blockchain technology by businesses. They will also lower the cost of entry by removing complexity and increasing the supply of developers capable of programming blockchain applications. Taken all together, the Nuls ecosystem will benefit developers, businesses, and cryptocurrency enthusiasts by providing needed solutions and increasing usage and adoption of blockchain technology.
