0x is an open protocol that is designed to offer a decentralized exchange as part of the Ethereum blockchain. 0x is made using a protocol that involves Ethereum smart contacts that allow those around the world to run a decentralized exchange. The team behind 0x strongly believes that in the future, you will find thousands of tokens from Ethereum and that 0x can provide an efficient and trustworthy way to exchange them. 0x have several benefits such as it can be any asset. The 0x protocol facilitates the exchange of a growing number of Ethereum-based tokens including currencies, game items, and many more digital assets. Besides, it has a networked liquidity. By sharing a standard API, relayers can easily aggregate liquidity pools, creating network effects around liquidity that compound as more relayers come online. 0x also can be exchanged anywhere. 0x allows trade functionality to fade into the background, enabling developers to focus on building while 0x handles the exchange. The co-founders of 0x are Will Warren and Amir Bandeali, the first of which is the CEO and the second of which is the CTO. Both are in smart contract research and development. Warren used to conduct applied physics research at the Los Alamos National Laboratory after studying mechanical engineering at UC San Diego. Bandeali used to be a fixed income trader with DRW after he studied finance at the University of Illinois, Urbana-Champaign. 0x doesn’t charge fees of any type to use their protocol; it is free. However, if someone chooses to create a decentralized cryptocurrency exchange using the protocol, that person, known as a Relayer, can charge fees. How does it work? 0x protocol works where : A “Creator” sends his request and at that same point the request is posted in an off-chain arrange/order book by the “Relayer”, next to which the request is acknowledged by the “Taker” by pushing the exchange into the task’s DEX smart contract. Thus, the 0x protocol uses off-chain order books, which is maintained by a relayer for settlement of trade between two parties. Relayers, being behind the maintenance and creation of these channels are incentivised by charging and collecting fees. 0x (ZRX) Token: ZRX token is the unique aspect of 0x project which will be used to pay ‘relayers the trading fees by the users of the protocol. It is also a governance token in a decentralized form for the 0x protocol’s upgrade.
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).
