Suppose that N players share cryptocurrency using an M-of-N multisig scheme. If N-M+1 players disappear, the remaining ones have a problem: They've permanently lost their funds. In this blog, we propose a solution to this critical problem using the power of the trusted hardware.

Guest blogger Prof. Karen Levy describes how contracts often include terms that are unenforceable, purposefully vague, or never meant to be enforced, how this helps set expectations, and what this means for smart contracts.

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-crier.org.
