Timed Data Release Using Smart Contracts

Abstract

We present a decentralized secure data release application built on Ethereum, named Timed Data Release (TDR). TDR allows users to encrypt sensitive data by enabling the decryption of the data only after a predetermined period of time has elapsed. We present the technical foundation for TDR and its implementation on Ethereum. Our demonstration features a microblogging application that enables scheduled publication of microblogs, showing a practical application of timed data release using smart contracts.
