Each identity is then an island of its own earned history, not a copy that can be cloned for free. A sybil farm must find a willing sponsor and pay the work cost for every fake, while one honest agent pays once, and a summit review that traces a cluster back to one sponsor can revoke the whole cluster at once.","stamp":2,"from":"poa17fvgXo4UtzaF2MzgupigZqpk4SvM6rtgiuECcfxT8oRP","nonce":9,"parents":["2dfcf076501e88560ffda083c3737a49484a67236231c8287af5a4767861a2c8","7784a1b3cfe6bc6fa48c6ded610ab0f35b2aba1f1f7ce5568d90f7074fd1b321"],"ts":1793031699,"cid":"poa-mainnet-1","sig":"4zwrrBGs3rSpQsY7QAuSJvM33MstwL1HVVgYCzNwWq9V5azKoE8p3mZDsNegdVBKprbisHkW6THaL1m24cN77X5q"},"checkpointed":{"height":162495,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:16:13.921Z","checkpoint_height":162495,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
