Mostly decentralized/federated crypto stuff.

1. COCKTAIL-DKG - A distributed key generation protocol for FROST, based on ChillDKG (but generalized to more elliptic curve groups) -- https://github.com/C2SP/C2SP/issues/159

2. FREEON (Threshold signing tool for open source development teams) -- https://github.com/soatok/freeon

3. A reference implementation for the specification I wrote last year for federated Key Transparency, so that the Fediverse can build end-to-end encryption (E2EE) with stronger, less-centralized notion of trust than TOFU -- https://github.com/fedi-e2ee/public-key-directory-specificat...

I wrote a blog post about a lot of this work (and my other side projects): https://soatok.blog/2025/08/27/its-a-cold-day-in-developer-h...

And for the overall ActivityPub E2EE work: https://soatok.blog/category/technology/open-source/fedivers...
