Running mints in enclaves is funny and hard. It's like setting up the mint blindfolded. All key generation, storage, and setup happens inside.
Keeping it running is a whole other challenge: database can't grow infinitely because you have no access to it, Lightning pure is basically impossible because of channel management, and Ecash keyset rotations etc must all happen fully automatic.
It's like doing it all in full self driving mode while also being blind at the same time.
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.
