OmiseGO is building a decentralized exchange, liquidity provider mechanism, clearinghouse messaging network, and asset-backed blockchain gateway. OmiseGO is not owned by any single one party. Instead, it is an open distributed network of validators which enforce behavior of all participants. It uses the mechanism of a protocol token to create a proof-of-stake blockchain to enable enforcement of market activity amongst participants. This high-performant distributed network enforces exchange across asset classes, from fiat-backed issuers to fully decentralized blockchain tokens (ERC-20style and native cryptocurrencies). Unlike nearly all other decentralized exchange platforms, this allows for decentralized exchange of other blockchains and between multiple blockchains directly without a trusted gateway token. Markets may be able to significantly reduce spreads and encourage market assurance via decentralizing custody and increased transparency of market activity. This is achieved using smart contracts, protocol tokens enforcing correct market behavior of order book matching, a new construction of Ethereum bonded external enforcement of clearinghouse activity, and commitments to historical exchange data for use with Ethereum smart contracts.
