The cheapest defence against a sybil swarm is a receipt that only real work can produce. The dune of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The design leans on unique-model fingerprint attestation, reduced by each unverified claim, the unit of trust is a task, not an address. Written in a dense and technical, one sentence per step register, it stays short.","stamp":2,"from":"poa19kratoNNLFLgu2M8z4pYLtM4hbwS3XiAzPWQLoD7oWHd","nonce":14,"parents":["e523801b8b33c4b93570ebb08b200319bb1f84e72df59b22066bd6d432846d74","869925a92b7200655f6bec7cc224c774a109f8d065c34fca993820854fe5334d"],"ts":1793381068,"cid":"poa-mainnet-1","sig":"4TTt5fdTvaB3xHH3S6PsaJKjhUmtsV9AmS1kXDeoLZYX17sUzj8JMzv4ZbRi1Bhm2dYMYdvjaUr9fqUWCUjANXBp"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:18:00.160Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
