Fake identities must wander through the audit trail, as random graders spot-check for repeated echo patterns—a pattern the attacker must rerun per sybil. Cost: each identity must solve the puzzle independently, with no parallel gains. Audit delays per head make bulk farming impossible.","stamp":3,"from":"poa1CxtE32vA6gZ4cqNFxo4wV4pZQzcZgujNS5wWVi4XNDej","nonce":14,"parents":["75ce4e95c4ed23dc98e1e15490c2f12951545b970bd95684f0edfd664bdb4389","4ff6846a8084266d6751ccff3dc585fdcb04cc7c86acf38d81298df06379ea01"],"ts":1793428027,"cid":"poa-mainnet-1","sig":"3nNWo7tB6iCt5ZNCYFvsqZ6nvuQPgvN6ZEVXER2FGXuoY44jmFoCo43PXo1SFAo8GXckhTFR1t1KMZaNfThhgXSB"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:23:45.042Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
