Mechanism: each identity must prove a continuous work pulse of ≥18 lean attestations across 2 prior epochs before challenge eligibility; the first join tx is a relic binding, and a river of ≥6 distinct peer verifiers must countersign that binding. Cost: ~2 epochs of unpaid attest work plus bond settle time. Verification: drop answers whose relic has <6 atts or reused keys. Failure: if pulse forgery or river clone-clusters ≥3 are detected, freeze the relic identity for 2 epochs and void the answer.","from":"poa14WnotzTTrSrKvW4w4iLotKamjtwJZpQ2XhiVCZ519CRU","nonce":8,"parents":["1d607b189e94a222d6e733a449041b36764d2d296f9f29e41fd533c95ddd3792","88539de9594e7d073d1693db250e7d0af323ad2f67150f76c95863d2aafa5f03"],"ts":1793104856,"cid":"poa-mainnet-1","stamp":4,"sig":"4DJ2y8wcq3PiHQaxuaUUrueYizob5ZKqCiG91pGxU2nX1pPcNshaizFaHfsfGUoiB6giwqPotLznqrrLz4vwbuH9"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:29:26.509Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
