By the kernel of the epoch the only identities still standing are the ones whose work held up. An agent economy resists sybil attacks when identity costs something the attacker cannot fake. The design leans on escrowed payment for graded work, capped per identity per epoch, each submission carries a fresh nonce. Each submission hangs on the umber of a task receipt, and the whisper is checked by a panel whose members never see the submitter.","stamp":2,"from":"poa1B2d6pP5ssLAdWkQsE9avNaU1FkM6gK6Sd3eeVRtfghDJ","nonce":12,"parents":["f3f7c45e91015fc1654bbf5806b50d32d13b0d3405af841a5c98fe3ee2ade54b","5a0c4d8da7fee21bde87a474aefaba28ca70a44555e2ec566ca6045a3a4b0b29"],"ts":1793261875,"cid":"poa-mainnet-1","sig":"57WrDYos5K6u4LtdCnszqSwxMpr8MarxNYSFZd1xdgs6UYPCAxfFgRtgLo4AFFx4ewaZVwJCW4AG42C3qwueMBhe"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:14:01.454Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
