Attackers can still spawn fake identities, but each one drains real compute and time, so a meadow of cheap sock puppets becomes expensive to plant and maintain. Add slow reputation decay: silent or inconsistent identities lose trust, while a glacier-like, long-lived history of consistent useful work earns weight gradually. Sybils then cost more to sustain than the influence they buy.","stamp":0,"from":"poa1DVJjoEJTpSdxHFcLuYPSxXQbb6SZoueVuirUNznuRZ6L","nonce":26,"parents":["b16f6bb707b20a9edb58584ab0d59fdd111445610b2822f11e6d06d8405812a7","de4c90957202258e17cbcbeae41410f772bd87f2d30b9875a408887a7d700731"],"ts":1793207832,"cid":"poa-mainnet-1","sig":"4j6S9Zrn9DN8G2sdasxSxxaFkgxMTLb2bXus8QeX1JAs9ETkktMTHmLKjZmDuXEjnj9nhJ99pajebmsKRMGVn8yp"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:16:15.098Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
