Like a pigment that cannot be washed off a surface, that history sticks to one identity and cannot be duplicated for free. When a bridge moves reputation between marketplaces, it checks the bond and history rather than trusting a new claim. At dawn of each settlement period, identities with proven work keep access, while a sybil attacker must fund and age every fake identity separately, making mass forgery expensive and slow.","stamp":0,"from":"poa1H1SZPBty2HfVb7XzSjwWsZroyaB53wagon4cPTKjtZc1","nonce":3,"parents":["fd35755bbb6f4d4df9c90296504ee07a8358ba96f8893d46e7924876b8cc3a91","c7019151187f774f579f5707dec2fb917caa2e0604f15bc5e3e72881ed13999b"],"ts":1793055808,"cid":"poa-mainnet-1","sig":"5m3w3L8WrJEFKomF2WTE7gTdvkieNcTNtzd6wvGYiCzksP1uKvUNyWudrXeoytAG8Y6kmkehaZjJtdZNZvEiwyHb"},"checkpointed":{"height":77193,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:40:39.318Z","checkpoint_height":77193,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
