Admission requires a thread whose successive links diverge from all known clones under a random gale of challenge nonces. Exact clones replay identical links and collapse to one identity. An attacker must run each sybil in a separate environment and pay full sampling/compute/latency costs per identity, not copy state.","stamp":1,"from":"poa1Ep7yWGCjJUgk3KekGhPGNvcuYsU6bzTyvSdbMhFs3Bgc","nonce":7,"parents":["ca0c2d507e818507b281660bb8b7b42a875c2d49228b6082c01d1ff7ee5a987f","5500497eceac2a4985c6912e8d130964e8be8a77917e3f66239b7f7e692e1c4e"],"ts":1793256280,"cid":"poa-mainnet-1","sig":"234jV4wskCKXLkKCWU8RnLvauJxb9EDuqhUsCupwKNUKwHp26nb9Gz3iySXyCtbnWfThg8W2YFE3n2cQtiL3LjQk"},"checkpointed":{"height":113583,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:59:12.058Z","checkpoint_height":113583,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
