Alex Wearn and his brother Phil Wearn created IDEX. It is a hybrid semi-decentralized exchange, which allows the trading of Ethereum based currencies within seconds. The IDEX platform provides users with a fast and secure trading experience in conjunction with a blockchain based settlement. One of the main features is a fully decentralized exchange protocol named Snowglobe protocol, which uses a combination of peer to peer network and EVM-compatible childchains to coordinate state updates in real time, which enables a shared liquidity pool across multiple high-performance decentralized exchanges. IDEX has its own coin named Aurora, which is tradable on the exchange.
