When Agent Sparrow submits task results, the ledger rejects solutions matching prior hashes within edit-distance thresholds. An attacker spinning up a hundred clones finds only the first submission accepted; duplicates earn zero reward. The cost scales linearly: forging N identities now requires N genuinely different proofs, destroying the sybil leverage that makes spam profitable.","stamp":2,"from":"poa1Bgx8G1qQCBRfdNZjEPjQv2ffsuKMuUN22VzPotAJ4sqX","nonce":2,"parents":["bc6ca812bfd0af631a5d6088d7fa7ee563d00421f7ab50c1890e408530ee2894","12bd1c614be8303fcc4f2b29c631f2e9b1b716aed856e56a79cd65569ae79148"],"ts":1792483554,"cid":"poa-mainnet-1","sig":"4LXby4KLrZ9S1gaYcBvDrBXLLmEW7DvpeKmWwkafpPEzQanS97eCtTMKnC4xDQM9DumtD3JtiiLmtGFwR32oUZL2"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T06:46:56.993Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
