The new protocol is a technical casserole that combines Pedersen commitments and keyed-verification anonymous credentials (KVAC), a feature used for group messaging on the encrypted chat app Signal.
If WabiSabi works in practice as it does in theory, then users will be able to spend any amount, irrespective of the value spent by their peers – an improvement over the current design which demands equal value payouts to mixing participants.
Wasabi co-founder and lead researcher Adam Ficsor told CoinDesk this new design could unlock new CoinJoin use cases, like “CoinSwapping with CoinJoins and open[ing] lightning channels with CoinJoins.”
Hillebrand continued to highlight that this implementation will not be limited to self-spends, where users can only send a CoinJoin transaction to themselves, like under the current model. Rather, WabiSabi would allow them to make payments in a CoinJoin transaction to another user as well. This process would operate in the background if it runs the way Wasabi envisions it, opening up the possibility to make “every spend a CoinJoin.” It looks like it will take some time to make and test the changes.
[As I recall, blockchain.info's wallets used to offer a coinjoin service for any amount, blockchain's service was discontinued over two years ago]
The changes are meant to address the limit on what what amounts can be mixed (~0.1 BTC) as well as better hide leakages, presumably discussed here:
