Join our special dev call this month, Thursday 16:00 UTC (links in the referenced tweet). It's our 25th monthly dev call, which is crazy.

A normal locked Cashu token says "I'm only spendable if there's a signature from public key Y", similar to how pay-to-public-key works in Bitcoin. That comes with privacy issues (like address reuse in Bitcoin).
With STARKs, the script basically says "none of your business mint, two people agree, here is the mathematical proof, just verify the transaction and stfu".
It's next-level scifi tech and afaik no project uses STARK proofs specifically for their privacy like we do.
Cryptography is the closest thing to magic I know. Join us.
