Legacy is a blockchain-based application allowing people to easily distribute assets upon their death or, in general, upon any given set of events. The application core functionalities are developed on the Ethereum blockchain. These include a Proof of Life engine responsible for determining whether the user is alive or not and a smart contract that manages user assets and schedules their distribution according to a given set of triggering events. Exploiting the unique characteristics of blockchain platforms, Legacy is designed in order to ensure security, reliability and long-term availability. Typical use cases include the transfer of: 1) sensible data (e.g., personal meaningful data) 2) cryptocurrency holdings and 3) confidential data such as account credentials of digital services. In the long-term, Legacy expects to integrate smart property as well as to provide a platform for peer-to-peer legal and technical assistance, thus becoming a next-generation smart will.
