ZRX is a crypto based on the ERC20 specification. The 0x project is a protocol used to create personalized decentralized markets, allowing to exchange crypto assets between users quickly and safely and with zero transaction costs. The 0x token is used to pay commercial fees to relays for their services. The main use of ZRX is to offer decentralized control over the 0x protocol update system, which means that ZRX owners have the authority to decide how the protocol should be developed over time. Due to its versatility and easy protocol availability, it won't take long for 0x to grow rapidly, providing the foundation for other similar exchange systems using the Ethereum blockchain. Although 0x has been operating for some time, it was after Coinbase's decision to use 0x for its market that has put it in the spotlight, as well as the listing of ZRX as a token that could be bought and sold on Coinbase. It seems clear that Coinbase is going to vastly expand the number of assets it offers and 0x is going to be the foundation which the new market is built on. When this happens, it is quite possible that other markets around the world will imitate it, and we may have 0x as one of the pillars of the crypto world.
