The newest block of each Bitcoin Knots BLAKE2b chain, decoded and validated here with the schema engine and its Knots overlay: header rules, block structure, and the contextual rules that need no UTXO set. Rules that need previous outputs are shown as skipped, not as passed. Stage 1: the block is a static snapshot from a Knots node.
how this works
The page loads data/tip-<network>.json: the raw block, the eleven previous headers, and what the node reported for the block. The engine decodes the block, runs the header rules over the twelve-header window (proof of work, linkage, difficulty, median time past, future time, version, timewarp, the fork rules), the structural rules (coinbase first and only, merkle root, duplicate txids, weight, legacy sigops, per-transaction rules, the committed transaction count, the fork headline), and the contextual rules with an empty UTXO set (BIP 34 height, witness commitment, the reduced-data weight cap). Inputs, fees, scripts, maturity and sequence locks need previous outputs, so they are reported as skipped. What the engine computes is compared with the node's own figures.
Engine: bitcoin-desktop/schema@v0.0.25 via jsDelivr, unmodified, with the knots-blake2b overlay. Next stages: live tip hash from the NIP-333 stream, block bytes from a source URL of your choice, then a worker. Source: play-grounds/knots.
