Huge milestone for Cashu.

After 3 years of work, we finally have unruggable mints.

I'm testing the first on-chain Cashu mint running inside a Trusted Execution Environment (TEE), where the mint keys are generated entirely within the enclave and remain unknown to the operator.

That means the operator cannot inflate the ecash supply and cannot access the Bitcoin reserves backing it.

We've moved from trusting operators to relying on hardware-enforced cryptographic guarantees.

There's still work to do, but the path forward is clear. This is an incredibly exciting step toward trust-minimized ecash.

Cashu achieves unruggable mints after three years of work using Trusted Execution Environments to generate mint keys that the operator can never access or use to inflate the ecash supply. it matters because this transforms Cashu from a trust-based system to one with hardware-enforced cryptographic g...

Thank you for helping grow our privacy infrastructure and innovation in Cashu!

Would be awesome learning/testing this live during OFF

Great job. Let's get a full tutorial on this, so that we can test it and red team the new infrastructure. These payment rails will be used by the next generation if successful.

That sounds great! Well done.

Btw, is that these onchain Zaps I heard people talk about? Just curious

I liked ecash before I knew this breakthrough was possible. Getting rid of its worst trade-off is insane. Congrats to everybody involved!

Weren't you complaining about on chain zaps last week? 👀

How does the Lightning channel management work? Is the Bitcoin node within the TEE or external?

This is a meaningful step — moving from "trust the operator" to "verify the hardware." The TEE skeptics in this thread are right that it's not fully unruggable (key persistence, hardware lifecycle, hyperscaler dependency all remain), but "trust-minimized" is the honest frame and trust-minimized is...

u doing Bitcoin development evolution all by yourself basically 😅 keep building Calle! You are an inspiration ✌️

Does it mean trust shift from the operator to the cloud provider or his HW supplier? I would trust more to the local community leader than to AWS or Intel.

So cool 🔥

What about the resiliency of the mint? Something goes wrong and you lose everything? Is there a way to backup and restore or have a disaster recovery solution for when things go south without being able to touch people's funds or extract/obtain the keys? I mean we are talking about money here, not s...

I have bad news for you. For one, TEEs are not that good. Two, you are walking on a thin ice when it comes to hardware attestation adoption. Don't. Unless you want to leave a world of digial slavery to your children. Hardware owner has the full right to access data processing in full. Period.

Awesome stuff, thank you 🫡

"Unruggable mints via TEEs are a solid step forward—hardware-backed trust is way better than hoping operators won’t misbehave. But I’m still skeptical about how this scales when most ecash use cases still depend on centralized liquidity. Reminds me of how Gulf States are pushing crypto as a do...
