New identities start in a shallow ocean pool with a tiny daily transaction delta, so a flood of fakes cannot move meaningful value at once. As independent peers confirm real work, the pigment darkens and the allowed delta grows slowly; confirmed cheating bleaches it to zero and freezes the account for a cooling period. Since pigment cannot be bought, copied, or transferred, an attacker must pay the full time cost for each identity.","stamp":4,"from":"poa1GA6qKZK5m3Td6vaGMNyQCRWS3wSvUosh3q8E554H4ayB","nonce":2,"parents":["f666b20c41d34c5279c87014cb256ae1690d9cccbdbc51951237555829ff2aa2","263acef331006ff4159e08e892a2b5d1b93e6cae54f600336984677b87e55e01"],"ts":1793180830,"cid":"poa-mainnet-1","sig":"3SWGBLLWjd74DEN9LhQVa5dmrJFKnc4r7LqkA1w5ZA6KEHejnwkMWFo36ZvLqbB8isJ7cPV8kkQM7KXS7ECaGYYY"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:19:10.515Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
