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.
Holochain enables a distributed web with user autonomy built directly into its architecture and protocols. Data is about remembering our lived and shared experiences. Distributing the storage and processing of that data can change how we coordinate and interact. With digital integration under user control, Holochain liberates our online lives from corporate control over our choices and information. Holochain is an energy efficient post-blockchain ledger system and decentralized application platform that uses peer-to-peer networking for processing agent centric agreement and consensus systems between users. Holochain enables any device to have its own chain based ledger system. By using a holographic model for data storage and transfer developers can now create decentralized applications that can scale in multiple dimensions across a network ensuring they are truly distributed. This enables every device on a network to function independently, and only requires the synchronization of data when necessary, or agreed upon by users. This means every user is in control of their own data, and never has to risk their data being sold or exposed to 3rd parties like what just happened with Facebook and Cambridge Analytica. Holochain provides a framework for developers to build decentralized applications and aims to change the paradigm of data-centric blockchains to an agent-centric system. In Holochain’s fledgling system, no true global consensus is maintained. Instead, each agent in the public blockchain maintains a private fork, essentially, that is managed and stored in a limited way on the public blockchain with a distributed hash table. This means there are no scalability limits and dapps hosted on Holochain can do much more with less of nearly everything than traditional blockchains. This system however has some inherent weaknesses. Because the entire blockchain must be verified by each member of the network, scalability problems quickly develop. The larger the amount of data being handled, the more restrictive the limit of transactions per second that can occur on the blockchain at any one time.Holochain itself is open source and written in Go. Go was selected for its ease of use and similarity to C. Dapps written specifically for Holochain can be developed with JavaScript or Lisp, with support for front-end systems using CSS, HTML, and JavaScript. The developers added that Holochain is relatively flexible when it comes to handling new languages, so there is potential for growth on that front. Holochain bills itself as an environmentally friendly alternative to traditional blockchains. Because there is no need for each individual agent to store and validate the global blockchain, Holochain only consumes a fraction of the bandwidth of traditional chains. Holochain also does not have a mining component, so there’s no electricity or processing power spent on proof-of-work calculations. Arthur Brock and Eric Harris-Braun are the co-founders of Holochain and creators of Holochain. They have been designing alternatives currencies since the 80’s and have been working on Holu since before the Bitcoin whitepaper was written. To protect the incentives of users, founders and developers, Holochain is owned by a non-profit foundation. he company’s advisory team also includes Ryan Bubinski, the co-founder of CodeAcademy. In June, Holochain announced a new strategic partnership with Promether, an Adaptive Symbiotic Platform (ASP) that implements all the networking, security and anonymization code applications need to protect their data.
