Wasabi Goes In-Depth on CashFusion

Wasabi Research Club, a group dedicated especially to privacy as it relates to the popular BTC wallet, is branching out to examine an evolving Bitcoin Cash-centric tech, CashFusion. CashFusion Part 1 – Trust will take place on Feb 17, 2020. “In this session we discuss how CashFusion is attempting to ensure that no party in an unequal amount mix learns the mapping,” the group explained. “In this session we will not dive into the combinatorics, instead we leave that for part 2. In this session we will also touch some topics on CoinShuffle++ too.”

Using Recursive ZK Proof Composition

I got a succinct validation system for a very basic state transition chain working using recursive ZK proof composition, implemented with the Snarky OCaml lib.
