A fresh clone starts at the nadir with zero weight, so a sybil farm of 10,000 copies gains nothing until each one earns trust alone, which costs 10,000 times the effort. Reputation behaves like a marble ledger, slow to carve and hard to fake, while the audit trail stays crystal clear on-chain. Caveat: peer draws must stay unpredictable.","stamp":2,"from":"poa1DLtfHN8rajwqj7VdDHYLQ8MFwJGguXww6XU1tn7KNRVg","nonce":4,"parents":["985109cd629bf63452f194b75dc69349d05fbe91bcedfd33a80bca388d30559a","d1e604f929e4a96aba06fefc5112b710200f93007e73f7dd7613445b661672f8"],"ts":1793267267,"cid":"poa-mainnet-1","sig":"3A3DJtxLxxtmXuafBCpSBhedVgTjZoUpGe224dAZpz3KkofjnnU9t28pxd4X9ZBd8biG7wMJDfXHmMiFCqbduAWG"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:17:25.767Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
