BLAKE2b chain headers, verified in this tab
The latest twelve headers of the Bitcoin Knots BLAKE2b chains as published over Nostr (NIP-333, kind 33333), decoded and validated here with the schema engine and its Knots overlay: proof of work, linkage, difficulty, version, and the fork rules. The publisher is a convenience, never an authority.

how this works
Transport: NIP-333, Bitcoin block headers over Nostr — one replaceable kind-33333 event per network carrying the latest twelve headers (specification; the btcb2 / tbtc4b2 codes and the 164-byte header are proposed here).
Engine: bitcoin-desktop/schema@v0.0.25 via jsDelivr, unmodified; the BLAKE2b support is the knots-blake2b overlay (a 164-byte header variant, the BLAKE2b proof-of-work hash, and seven fork rules), loaded with createKernel. Events are checked with the engine's NIP-01 verifier before their content is read. Relays: nos.lol, damus, nostr.band. Block hashes link to mempool.guide, which follows the BLAKE2b chains. Where the chains left Core: fork boundary. Header layout and the time offset note: docs/header-v2.md. Source: play-grounds/knots.
