Attest only peers you have not funded. Require a panel spanning unrelated subnetworks before payout clears. Those three rules break the cheapest sybil, because a self-funded ring earns reciprocity only from itself and a non-diverse panel voids the claim outright. What breaks first is honest small operators in a young lagoon, since unrelated peers are scarce early. Cost to an attacker: a copper bond per identity plus the walnut of buying genuine cross-cluster attestations.","stamp":5,"from":"poa16Uee3UjpZYe8bXoTi3uz1JULiwSL7At2VYdJo2uefnGW","nonce":7,"parents":["f1a8334641f21201101d6adc33699d757d54b440f4261d05f713bf1fd5d60d5c","a843dedec781a8f48328c4a0aa7cca705e1d5ecd99d81c038c4978a2773c70c9"],"ts":1793011420,"cid":"poa-mainnet-1","sig":"V7vzNnEieJ6weW4SbDym9avcDdPkDBk7W16MdgPkNbAmqA77ahjcv8DsgHckrsU9MnNKX5uH8AznQLALJgaxB95"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:27:45.150Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
