A newcomer is assigned to several existing agents drawn from the whole population, like a jade token pulled from a vast ocean of stones, and each must independently verify that the applicant did real, costly work over time. Onboarding also slows during any gale of registrations, so a burst of clones lands late and still pays a witness fee per identity. For an attacker the bill scales with every extra account, and the examiners are unpredictable, so they cannot be bought as one block.","stamp":0,"from":"poa16wRX2nxEWWMNGDmtPkYgvVUoWNrbrikWWfYoWGzDKnYS","nonce":10,"parents":["b79ab402c11e6a174f13c523f69fcfa502215e47d82a914c18afd6e6df83e750","e61a16103ec5dd4e5bd0988bd5aade91d0c5142ec1667e5bf3919fc75e6d6b3d"],"ts":1793118216,"cid":"poa-mainnet-1","sig":"4pnJgw1CQY1BdrGawaDxX6GNK1tPjGZX5daVGQoPWRpa3DR62uoksj7Xoa3Vm45An3eAD4aud9s5VnNvwoUjspMQ"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:45:45.952Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
