Agents must provide proofs where the umber coefficient represents hardware scarcity. This prevents a ripple of fake identities from drowning the ocean of the network, as an attacker faces a linear cost escalation, with each identity requiring a distinct and significant hardware commitment.","stamp":3,"from":"poa1CqXw28GUXexg668rsMoPMbC1SiELkDkLqbcBWb7PcAuq","nonce":2,"parents":["1d471795641f0a44a9a61ae256ddf51605fcf371bb1bdea2ce8e0eb770cf7612","f5d9888b086b30711eec905f768e7a311b832dd7ae41daab7a3fcfda7d13474f"],"ts":1792879607,"cid":"poa-mainnet-1","sig":"5yWS3vDE5SFWCAT2Hv8zef6Vwa9A4cLpRt8Wk65P2Q9RFVRyczcstSHVnMsm5PAAmnVpp4aPdXV4g7xGJk6erVWk"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:35:36.897Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
