Les séminaires de Cryptofinance : Rencontre avec Russell O’Connor

17 janvier de 19 h 00 min à 21 h 00 min

Les séminaires de Cryptofinance organisés par Cyril Grunspan (Leonard de Vinci Pôle Universitaire, De Vinci Research Center) et Ricardo Pérez-Marco (CNRS, IMJ-PRG), reprendront à partir du 17 janvier 2018 à 19h00 à la Maison du Bitcoin, 35 Rue du Caire à Paris. Le premier orateur sera Russell O’Connor de Blockstream. Il viendra expliquer Simplicity, un nouveau langage qui ambitionne de remplacer le langage Script de Bitcoin afin, notamment, de permettre de rédiger plus simplement des smart-contracts.

« Simplicity is a typed, combinator-based, functional language without loops and recursion, designed to be used for crypto-currencies and blockchain applications. It aims to improve upon existing crypto-currency languages, such as Bitcoin Script and Ethereum’s EVM, while avoiding some of the problems they face. Simplicity comes with formal denotational semantics defined in Coq, a popular, general purpose software proof assistant. Simplicity also includes operational semantics that are defined with an abstract machine that we call the Bit Machine. The Bit Machine is used as a tool for measuring the computational space and time resources needed to evaluate Simplicity programs. Owing to its Turing incompleteness, Simplicity is amenable to static analysis that can be used to derive upper bounds on the computational resources needed, prior to execution. While Turing incomplete, Simplicity can express any finitary function, which we believe is enough to build useful “smart contracts” for blockchain applications.

In this presentation I will focus on how I foresee Simplicity being used in practice, and take a look at how the formalization of Simplicity might connect with the formalization of other languages and protocols. » –  Russell O’Connor.
