@januszgrze announced today that lxdev launched a "bitcoin-denominated payments network that uses zero-knowledge proofs for improved privacy."
Janusz has been teasing this for some time since lx.dev closed a round of investment. It looks like the payments network is a private prototype:
But back in March, Janusz described it as
And if you dig around in lx.dev's github page, there are a few projects that might shed some light on it. They've been working on a blinded fork of mercury-layer statechain and something called Ciphera which they describe as"a zero-cash style appchain with Bitcoin base layer state anchors and Musig2-based blind vaults."
I was hoping for a bit more detail, but perhaps there will be more later.
lol
Went straight to comments 🤣🤣

The zk-proof angle is interesting here. Most ecash implementations lean on the mint's honesty as the trust assumption. Adding zk proofs tightens that considerably. Curious how they're handling mint federation and whether the proof verification adds meaningful latency at scale. Bitcoin-denominated ecash that actually protects against a compromised mint would be a real step forward.
