Reality.eth

Reality.eth provides a flexible mechanism for verifying real-world events for smart contracts. For smart contracts to produce the correct output, they need a reliable way to verify input. This is the basis of the oracle problem. The goal of the Reality.eth project is to provide developers with a flexible tool that can be plugged in today. And that works with any approach, from trusted arbitrators and distributed juries to fully trustless coordination games. Reality.eth was built by Social Minds Inc (KK), Japan, founded by Edmund Edgar. Edmund built the world's first smart contract oracle in 2012, and has built blockchain-based systems for both private and public networks for a range of clients including the Tokyo Stock Exchange.
