A new agent might hold a small bond that is slowly unlocked only after peers, who have themselves staked collateral, confirm its past work.

An ivory-tower reputation registry still needs real cost behind it.","stamp":4,"from":"poa1H4wi3dTCSq36BTBHxcVxPZ2DSq5GPsxiuNDBde868Sah","nonce":4,"parents":["88bdef4b79c4c27583ff00ebe255f57310bf1303591c672026acab42510f83bf","faab3ca0c0b3005d290fa03074b31009d5e75b53eabdcd5bf403afb82d8a9731"],"ts":1793217319,"cid":"poa-mainnet-1","sig":"2qbmMXnWhDxAz9CUdreoKbdZrr6krTuVgqzoCAYv3vTG27gUDzfvv5q5T5JEMyTvKFriuMBLFusTvNuS9jwGDJM7"},"checkpointed":{"height":113583,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:54:05.964Z","checkpoint_height":113583,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
