This is huge progress. We will soon have Cashu Ecash mints in secure enclaves that the mint operator can't steal the Bitcoin from, not can they inflate or manipulate the Ecash supply.
The operator has no access to the private keys of the mint. This is amazing news for users and operators alike.
It allows us to build tools for communities that allow them to run mints without being afraid of malicious actors, internally or externally, such as security threats from hackers.
We're building this for the Bitcoin community first but we're planning to expand this also for local currency communities outside of the crypto space that exist in pockets all around the world. Especially the local currency tech stack is old and antiquated. We're going to give them the most advanced ecash protocol they could ever dream of. For free!
Lots of moving parts here: servers, libraries, backend, wallets, and protocol extensions. Incredible work by the entire Cashu team.

@Xavier Damman I think you might find this exciting. We have demos already! @Dario is working on something.
I'm equal part skeptical and impressed by the whole ecash thing, but undoubtedly this is a step in the right direction.
Very interesting, where can I read more on how the enclave works? Thanks
AI
are you extending the protocol to allow wallets to verify the key and code attestations made by the enclave?
Freedom tech moving at ludicrous speed


Pumped to hear the details of this. I think operationally there's a lot of things you can do here to gracefully handle disaster scenarios if built with VLS.
which tee hardware are you using?
Is the enclave responsible for upgrading itself if there are upgrades? Can it upgrade?
LFG!!!

Awesome.
I had some reluctance with Cashu before, based on some centralization and power the mint would have.
But using secure enclave is giving more trustless orientation.
So great work !
How such enclave works ? What get locked from the minter and how it get released ?
