Abstract: 
Mimblewimble is a payment protocol that underlies several cryptocurrencies and is now also supported by Litecoin. Besides offering privacy by design, it improves on scalability: while in Bitcoin every transaction must be stored forever, in Mimblewimble only the "unspent transaction outputs", which represent the current state of the system, must be kept. In joint work with Michele Orrù and Yannick Seurin, we have formally shown the security of Mimblewimble (EUROCRYPT'19), as well as that of a recent extension (ia.cr/2022/265).
