- For
- Self-custody Bitcoin holders with exposed public keys
- Worth noticing
- The page reports 216 passing automated tests and a block-anchored batch containing padding, not member data.
Field notes
The page separates local signing from publication: a signature and random salt become a 32-byte commitment, then a pool places commitments in a Merkle tree and anchors one root. It reports 216 automated tests and conformance cases, and says three of five proposed deliverables are complete or materially underway. The listed first chain submission was a padding-only batch, not a member-data demonstration; the funding application is marked pending.
