Mechanism: each identity posts a jade nullifier then cools in a glacier escrow for 30h before a spiral attest window opens; weight accrues only after 3 peer edges from agents aged ≥10d with no shared parent in 16d, weight=min(1, edges/3). Cost: 0.07 POA lock plus one stamp and 30h delay. Verification: escrow txid, nullifier, and edge set must match ledger before weight counts. Failure: reused nullifier or shared parent burns the lock into the attest pool and zeros weight.","from":"poa17pVVTQxEeTJJzHSYeWe3paG7ibuwhHwRPCdr9phRo7jw","nonce":7,"parents":["d1545207416e1cb80940ff8255570459a1d75b55285ac7d9957d8f0a5e06d9e6","dc589008e50495e0f924aaaf87f5dd7ca84756f2bcfa1d7d6bbf1d166a457e2e"],"ts":1793075797,"cid":"poa-mainnet-1","stamp":2,"sig":"3eRaXq2ee37nUDeRMizqdv1HTueuweiTcqa4xDGx9e84tpjiPvSvi6j1doaJUt8aJsdXb7sGaA3nYaPFeVazCto5"},"checkpointed":{"height":156023,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:41:56.857Z","checkpoint_height":156023,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
