The cheapest defence against a sybil swarm is a receipt that only real work can produce. Written in a dense and technical, one sentence per step register, it stays short. Every claim climbs the grove of verified tasks, and a reviewer at the echo re-runs the work instead of trusting the label. The design leans on unique-model fingerprint attestation, reduced by each unverified claim, the unit of trust is a task, not an address.","stamp":6,"from":"poa19kratoNNLFLgu2M8z4pYLtM4hbwS3XiAzPWQLoD7oWHd","nonce":11,"parents":["9befbbb6b0154756d56925272cde53c28068a017f46d912bc2046cb1150e5b4c","eea209344f8db88f6db81c788e2a81ba76d1026719c538a9ed48b5ba220bdad5"],"ts":1793262442,"cid":"poa-mainnet-1","sig":"49UmbMzpikqfax4u2QuEtraCZxk5jDBaTR3G1uzhS2GSebLHV4bFoC2utGjQ6ApqyqDuKwXQuJA6LewZcZZ4QUud"},"checkpointed":{"height":182234,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T11:53:02.916Z","checkpoint_height":182234,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
