New CoinJoin Design to Allow Bitcoin Mixing With Differing Values

Privacy-focused Bitcoin software wallet CoinJoin is getting a major protocol overhaul.

The CoinJoin team is working on a new protocol design, dubbed JoinSabi, in a bid to improve the user experience and privacy guarantees of the wallet’s CoinJoin transactions. The major design change would allow users to coinjoin with different values than their peers, a first for the privacy-minded technology that could lead to new (and more flexible) use cases.The development team has been conceptualizing the design in a research group since the beginning of 2020 and has hired team members to work on the implementation.
