title = "The Ekiden Platform for Confidentiality-Preserving, Trustworthy, and Performant Smart Contracts",
abstract = "Although smart contracts inherit the availability and other security assurances of the blockchain, they are impeded by lack of confidentiality and poor performance. We present Ekiden, a system that aims to close these critical gaps by combining the blockchain with trusted execution environments.",
