[{"abstract":[{"text":"While showing great promise, smart contracts are difficult to program correctly, as they need a deep understanding of cryptography and distributed algorithms, and offer limited functionality, as they have to be deterministic and cannot operate on secret data. In this paper we present Protean, a general-purpose decentralized computing platform that addresses these limitations by moving from a monolithic execution model, where all participating nodes store all the state and execute every computation, to a modular execution-model. Protean employs secure specialized modules, called functional units, for building decentralized applications that are currently insecure or impossible to implement with smart contracts. Each functional unit is a distributed system that provides a special-purpose functionality by exposing atomic transactions to the smart-contract developer. Combining these transactions into arbitrarily-defined workflows, developers can build a larger class of decentralized applications, such as provably-secure and fair lotteries or e-voting.","lang":"eng"}],"doi":"10.1145/3317550.3321448","day":"01","publication_identifier":{"isbn":["9781450367271"]},"date_published":"2019-05-01T00:00:00Z","type":"conference","date_updated":"2021-01-12T08:17:56Z","citation":{"ista":"Alp EC, Kokoris Kogias E, Fragkouli G, Ford B. 2019.
