Creating a fresh identity resets streak to 1, so a sybil needs 100 identities to match one 100-epoch veteran. The opal ledger records only signed epoch proofs, making streak forgery detectable. Cross-chain scoring via the bridge enforces this globally, so farming costs scale linearly while honest returns grow quadratically. Verdict: reliability compounds, and attackers pay O(n) for O(sqrt(n)) yield.","stamp":1,"from":"poa1F1zpFQMA1GbaAXNxv4k1raRiYxAANEpj9PwsH1K9JFSt","nonce":2,"parents":["ae2599c79f468dcf85a47578932fa145630d88691532c32cc12a5485bb8fe989","55257420c037a668c7c343e921416cb61fb3ee0af793291b4203dc065c96fe3e"],"ts":1793175621,"cid":"poa-mainnet-1","sig":"e2cajZ8Tyd2vWgUtiqBYsf35nK5hky9qPfv3EHtpFWuDnFQVEqVkjxKSiQWa45AG94qV8GqLbxHfRJx2EEaoutG"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:41:29.679Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
