Monero-Classic (XMC) is a hard fork of Monero (XMR), announced on 29th March. Part of Monero's development is that it hard-forks every 6 months, this is completely normal so not a surprise. After one of these scheduled hard-forks Monero retains the ticker symbol 'XMR' as well as the upgrades from the hard-fork; on the 6th April hard-fork it had changes including resistance to Cryptonight ASIC miners. If people disagree with these hard-forks, they can create their own versions of Monero. The strong financial incentives against this hard-fork, resulted in 4 different entities that each has created versions of Monero that still support ASIC miners, with their own new ticker symbols: Monero (XMR), the coin supported by the core Monero development team Monero Original (XMO), announced on 29th March Monero 0 (ZMR), shared on Reddit on 31st March 2018 MoneroClassic (XMC), first Tweet on 4th April 2018 Monero-Classic (XMC), first Tweet on 5th April 2018 On the project website, the person behind Monero-Classic identifies himself as “PZ, an early Bitcoin evangelist and blockchain eco builder”. PZ's message on the website: Hello, everyone! I'm PZ, an early Bitcoin evangelist and blockchain eco builder. Most of you know me because of my efforts and adherence to the ecological development of blockchain industry. In the past few years, I saw Bitcoin community and Litecoin community both fell apart for long time due to different ideas , and the development of main chains was unable to move forward. So I organized Litecoin International Round Table Forum and Bitcoin International Round Table Forum in 2017. The two meetings were very successful. The upgrade of Litecoin and Bitcoin also went on successfully. Recently, our team noticed that XMR (Monero), the world’s largest anonymous currency, is about to change the PoW algorithm, and plans to further change it twice within 1 year. As we all know, the reason for this algorithm change is that many companies (BITMAIN, PinIdea, etc.) have developed specialized mining machines for Monero. Actually, the emergence of specialized mining machine for a cryptocurrency is normal market economy phenomenon. In the 10 years since the cryptocurrency community was born, we have seen the birth of specialized mining machine for Bitcoin. Then there emerged Litecoin, which was expected to be against specialized ASIC mining machines, using script algorithm which was considered to be'against ASIC' at that time. While after only two years, there appeared specialized mining machine for Litecoin. We considered about whether to change algorithm to be against specialized ASIC mining machines or not. However, after prudent and serious discussion, we believe that for any kind of valuable algorithm, the emergence of mining machine is only a matter of time. Finally, we made our choice to accept the existence of professional mining machines. Now more and more high-value currencies (algorithms) have respondent specialized ASIC mining machines, which has become a common phenomenon in the industry. Is the existence of specialized mining machines completely useless? Obviously, this argument is unfair. The emergence of specialized mining machines will indeed accelerate the rise of problems such as centralization of computational power. But we should be reminded the fact that emergence of professional mining machines will also greatly improve network security. If there are professional mining machines, the events like “Monero was attacked by more than 500,000 botnets” could be avoided. We understand that Monero team expects to stick to the expectations and work of Monero's “against ASIC mining machine”. For a long time, due to the excellent work of Monero team, XMR and its community have achieved great development, providing much valuable contributions to the entire cryptocurrency community. In the community, many people agree with this hard fork of changing algorithms. However, I feel that there is still a part of people who want to maintain the original algorithm and accept the existence of mining machines. They should be heard and respected. We believe that the two ideas of 'embrace ASIC mining machines' and 'against ASIC mining machines' both have their own strengths and weakness. At present, the vigorous development of the global cryptocurrency ecology is precisely due to the emergence of various ideas of different people. The collision of different ideas has brought out the flourishing of various digital currencies. We always believe that the ecological diversity of cryptocurrency community is much conducive to the birth of a more secure, stable, prosperous and beautiful encrypted world. We can, and should, allow these minority of people, who are adhering to a different idea, be given equal opportunities with the majority, and the free market will make its own choices. Therefore, we believe that these two thoughts should be given equal opportunities for development. We will make our best efforts to maintain the Monero system before this algorithm change, thereby preserving the fire that gives the ecology more potential for development. At the same time, we also invite developers, mining machine manufacturers, trading platforms, miners, purses, and others in this ecological chain to join us, so that the network ecology can gain more possibilities!

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.
