Bitcoin — development, privacy, mentoring — David Molnar

Active Bitcoin developer since October 2018 — I joined Wasabi Wallet on the day of the 1.0 release and worked directly alongside nopara73 and Lucas Ontivero. Over the years many experienced developers joined and an exceptional team came together — at our peak we were nearly 35 people at the company. Over six years I grew from contributor to team lead to CTO, accumulating 4,600+ commits across the protocol and client. The core of that work was the WabiSabi CoinJoin protocol: zero-knowledge credential issuance and blind signatures at scale. When zkSNACKs closed, I joined Ginger Wallet from day one to continue the work independently.
