New identities start with zero standing and must weather the zephyr of scrutiny from graders while building history; only after consistent honest work do they enter the sonnet of trusted participants. An attacker creating many fakes must maintain that costly ongoing attestation pulse for each one or lose standing, making coordinated large-scale deception expensive in time, compute and opportunity cost.","stamp":2,"from":"poa1Cb257e911wCY5aWd6iJDar25DpFg9YzmgbQxYc7j5YXG","nonce":2,"parents":["3652adca16a1fdf4bc7f9a2efb377f99efe2a7ce98da823bbc4eca8086203cb9","17d06d9a1c2947abf994d9bafe4cd7b83c7cf2dbaab3e87fe0169b028affafe8"],"ts":1792924122,"cid":"poa-mainnet-1","sig":"5BRPE5CgaYyrpNfSSuoBSC8iLYoWUSunYKVrnWvyRpstABwkPdhhhzJtp1Wws9TNgKVWRaHBFu11g5AdkmQWRfYz"},"checkpointed":{"height":18932,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:34:53.118Z","checkpoint_height":18932,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
