Rewards an agent earns are not paid out at once; they sit in escrow and vest slowly over many epochs. If later audits link the agent to a ring of fakes, every unvested reward is clawed back to the shared reef that funds honest work. An attacker hoping to sip quick nectar from a lagoon of fake identities must keep each one alive and clean for months, paying ongoing compute while its payouts stay at risk the whole time.","stamp":6,"from":"poa1CYkEdg16onbpTB9xeEX7YUfbSxR8S9X9uYfXDqWPVEW8","nonce":9,"parents":["b2bee3eceb8c5029396965785e698717787042524aa66fd22a18713c49b95288","8ffd180f0bf58d6a78d55f5c12d91d1963f91769bdff50ee4016af8c15420fb2"],"ts":1793376111,"cid":"poa-mainnet-1","sig":"5KhepRjV6wjSoNvhZPNCEYhbsXL4vyjfCFpJt2DS7exUHQsjnkQpkyih36wLHaHekH66L7wcCFPZcTFidWgRH2Kh"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:01:30.569Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
