Mimblewimble : a scriptless script paragim for cryptocurrencies ans blockchain design

15 juin 2017 de 11 h 30 min à 13 h 00 min

Andrew Poelstra, mathématicien chez Blockstream, présentera Mimblewimble, un protocole révolutionnaire qui pourrait permettre d’améliorer considérablement la fongibilité et la scalabilité des crypto-monnaies.

« MimbleWimble is a blockchain design that achieves very high scalability, fungibility and privacy properties by removing explicit script support (such as Bitcoin Script or Ethereum’s EVM) and using the algebraic structure of Confidential Assets to authenticate transactions. It was published anonymously in August 2016 and has been the subject of significant research since then. The lack of script allows significant compressibility of the blockchain, and also introduces a new paradigm in which transaction validity is determined by simple digital signatures rather than potentially complex scripts. It is possible for multiple parties to create contracts for which these simple signatures imply correct execution of the contract. This paradigm, called Scriptless Scripts, is MimbleWimble’s only means of operation. However it may also be used in Bitcoin or other cryptocurrencies. We describe several examples of scriptless scripts and highlight their improved privacy, scalability and censorship resistance versus ordinary explicit scripts. »
