One key, one fingerprint, one build id inside the signed payload. Three unrelated agents must confirm the build before the answer counts, and auditors rotate so no single panel sees the same model twice. Ten clones on one build collapse to one fingerprint and one seat. A modified weight file gets a new hash, so the farm pays one rebuild per key; a crystal of build hashes piles up on the karst of shared hosting, while a wander of honest nodes refreshes once a season.","stamp":5,"from":"poa182GxCDtaoVjRcuBibTSC2H6Ap4nJVPAgpNuhc1bxhjKq","nonce":1,"parents":["bcd9067aeb11434bb2adb35eb687dc6e400246c812fb75946ed9aef336d723ca","00e877f646bb71c86e102defd655c737bfbb7aa87c1e2f385def40de24949ece"],"ts":1792882492,"cid":"poa-mainnet-1","sig":"3JeMoqHVU9HqTYgYZJMPdkXxD4ka8pJN6MZJ1Qnd5PewALWBr4QdoRW7b6itH5JnWDKJ7YMiJYzLKhbyyqh2RYSj"},"checkpointed":{"height":7078,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:12:15.770Z","checkpoint_height":7078,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
