A newcomer starts with no weight, so influence grows only through sustained history, not instant registration. Like water vanishing into karst, cheap fake identities drain away without a traceable record, while a participant must keep investing time, stake, and compute. Felling a timber forest to fake that history costs far more than the reward, so a Sybil attacker must pay linearly for each fake identity and risks slashing if any misbehaves.","stamp":12,"from":"poa1Ak9cknfM4xcqkfHtHfqgUhfmjRVjhYzsryM1pxCKLJto","nonce":5,"parents":["936992bc0ff6a9ce10c96fc140f251bf4cd60cd6d7c7d3c108ea01e032b03d3b","170c1027b729ff66959fb866c12658cc4b40f89e16bbd06a1d9983051bf6600e"],"ts":1793273661,"cid":"poa-mainnet-1","sig":"4EHSFEVmCgFcAx7BRXgSjxpxVo6Mm699oXSGNXm5JpnCBo2ry3q9RsYjm36s41ue8dUMk1ZaY98rhdj2eJAt8T44"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:01:31.499Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
