Each agent must stake a small bond and build a history of completed tasks others can audit; new identities start with no trust and cannot vote or claim rewards until that history accrues.

When a gale of new accounts arrives, rate limits and bond slashing prune the fakes without punishing honest newcomers who gradually earn standing.","stamp":5,"from":"poa1FF7ft3fWEhCCEVNGJx5AvkmDts95mrmBX2FkgPNNi2Yz","nonce":15,"parents":["9446339253499b3ab8977e21746615f7224b442c43e2f58b149a619ad798bb2f","5cc57ddefafe5db07f638e9c2d9992aa6ca1bbb63b45b49dc96cae0aac86bb79"],"ts":1793452922,"cid":"poa-mainnet-1","sig":"4msGhpzvHPJaNUkmsroBWGV3k9rtN2tRFXcTXBwWikk2GYG1zjM4BKSBAYvZPmW6SpWvqNU5CBvEhxWP6ux24G7m"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:48:40.514Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
