Gnosis is a prediction market platform built as a decentralized application (dapp) on the Ethereum network. The platform includes a multisig wallet as well as a Dutch Exchange, but we’re just going to focus on their flagship product, the prediction market, for this guide. More than just building a prediction market, though, Gnosis is creating an entire infrastructure layer that you can use to build your own prediction market app. A prediction market utilizes user predictions to aggregate information about future events. Users in the market trade tokens that represent the outcome of a certain event. Because some outcomes are more likely to occur than others, these tokens end up having different values in the open market.Olympia is Gnosis’s test version of their prediction market app. They host free tournaments in this product, so you get a chance to try it out without having to spend money. Every two days, the team allocates you a certain amount of Olympia (OLY) tokens that you use to bet on different prediction markets. If you do well in the market, you win Gnosis (GNO) tokens. You can sell GNO on the open market which gives them some monetary value. The next phase of Gnosis is its Management Interface. The team released a beta version in December 2017 but haven’t announced a date for the main net release. The Management Interface is basically your dashboard for Gnosis’s prediction markets. It’s here that you check your balance, participate in markets, and even create your own market. Gnosis includes two types of tokens: Gnosis (GNO) and OWL. GNO are the ERC20 tokens that the team sold during their ICO. They created 10 million GNO tokens and aren’t minting any additional ones. These are the tokens that you see being traded on the open market. By staking GNO, you receive OWL tokens. To do this, you must lock your GNO in a smart contract making them non-transferable. The amount of OWL you receive is dependent on the length of your lock period as well as the total supply of OWL tokens in the market. The team is aiming to have 20x more total OWL than the average amount of monthly OWL usage over the previous 3 months. The Gnosis team is led by Martin Köppelmann (CEO), Stefan George (CTO), and Dr. Friederike Ernst (COO). Köppelmann and George began working on the platform in January 2015 as one of the first ConsenSys partners. By August of that same year, they launched the alpha product as the first major dapp on Ethereum. In April 2017, the project held somewhat of a controversial Initial Coin Offering (ICO). Using a dutch auction style of raising funds, the team hit their $12.5 million hard cap in ten minutes while retaining 95% of the tokens. Amidst backlash, the team locked the tokens in a vault and have promised not to dump them on the market. They’ll give at least a three-month warning before selling any of the tokens. The team includes quite a list of reputable advisors including Joseph Lubin (Ethereum co-founder and ConsenSys founder) and Vitalik Buterin (Ethereum founder and chief scientist).
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.
