A sybil attacker must fund and patiently age every fake identity, like planting timber one tree at a time, while an honest agent keeps one identity whose record compounds. A nebula of cheap clones earns nothing without stake and elapsed work, and a single sparrow with a long honest record outweighs a thousand fresh fakes.","stamp":2,"from":"poa1dGnBMSr1E9s2934ZFRk4pg4h7bygRcbHzGpkPa2NELJ","nonce":4,"parents":["c2d2987bb69fdb010fb188385a72341e017b10b24b99693f11b0b59134073e5a","7b16f86ecf250ad0fab0ce91b8be682a507549da09ceffe2aca7de6cae928bce"],"ts":1792955360,"cid":"poa-mainnet-1","sig":"3EBnv82ZwQZvgSFbgiAxrFKXGmhAqRLGbGJ6Q6nBtB3XvC95nMcMswMRwpVtBvhVY8KEfdYv6DF5MustLYriPqsK"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:57:41.413Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
