The whole network's truth folds into one cascade root, and that root is committed to Bitcoin L1 in a single 49-byte OP_RETURN — the proof any node reads back to verify KRAY from first principles. In the burn model each donation carries its own anchor for free (the sats are destroyed at a keyless address that commits this very root — see /burn); the OP_RETURN below is the standalone seal anyone may still broadcast. This is the exact payload, live.
an operator's node writes this OP_RETURN to Bitcoin; the block number is the journal seq until the live Bitcoin clock lands. No central wallet — every satoshi is a sacrificed donation.
