New open source tool: tss-ceremony

An interactive terminal animation of a DKLS23 threshold ECDSA signing ceremony. Real crypto values, real signatures, verifiable with OpenSSL.

Built with Go + Bubbletea. 20 scenes walking through keygen, signing, verification, and a FROST comparison.

`go install https://github.com/DisplaceTech/tss-ceremony@latest`

Private keys are single points of failure. We've all known this, but we treat it as an operational problem — HSMs, rotation schedules, access policies.

Threshold signatures make it a *cryptographic* problem instead. DKLS23 splits a key across parties so no one holds the full secret, and the output is standard ECDSA.

I wrote up a plain-language explainer: https://eric.mann.blog/why-one-key-shouldnt-rule-them-all-threshold-signatures-for-the-rest-of-us/
