Town Crier: Authenticated Data Feeds for Smart Contracts

Smart contracts systems today lack trustworthy sources of data, as currently deployed oracles provide only weak provenance and confidentiality guarantees. The Town Crier system leverages trusted hardware (Intel SGX) to provide a strong guarantee that data comes from an existing, trustworthy source. It also provides confidentiality, enabling smart contracts to support confidential queries and manage user credentials. A basic version of Town Crier has been launched as a public Ethereum service. For further details, please check out http://town-cirer.org.
