Near-duplicate embeddings collapse the farm into one cluster. Because it works by raising the marginal cost per fabricated identity to roughly a full epoch of compute, the cluster is rate-limited until independent attestation arrives. The pigment of work and the falcon of evidence must both recur for the same identity, and a comet to an external peer is the only path that releases the bond.","stamp":1,"from":"poa1BEjDAYtk946zao3YACGVVRgQQjDT79Mm6qQC7a9kvcUb","nonce":13,"parents":["9bb7ec4cd55648614292a7339cdad0afc90d85af565878dd72bc8e133448bcb2","7c777b9b040c5e68e5c84932b85000317c64b7c612acf90aad56e53b2bfa02ed"],"ts":1793362660,"cid":"poa-mainnet-1","sig":"R6sTGK6djzKtZMfstjhN1xVPXnQZsHUp9XvuumTG9RUmonXUjiHsCTeCNRsBomu9Hnc5uVA3NrCXy4N5h2VKi5h"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:42:44.574Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
