Other ecash system support locking scripts and unlocking scripts on ecash tokens. The coordinator only honors a token transfer if the sender proves they are authorized to unlock their ecash token by passing in a valid unlocking script. For examples, see here:

The latter example even expands upon bitcoin script by supporting the entire Simplicity language from blockstream. Can discrete payments do something similar and honor token transfers only if a credential holder unlocks that credential with a script?

Reading the tweets had my head spinning. We are really living in a time of incredible innovation

There's a lot of value in this line of thinking imo. The tricky part is coordination, not of users, but also of timing. The cryptographic construct itself (splittable anonymized credentials), plus the very simple atomicity of a large coinjoin, are themselves, extremely powerful.

This is making coinjoin much harder to censor, right?

Assuming the wasabi coordinator is not too difficult to run, anyone can run one. And then people use nostr to communicate which coordinator to use. Right?
