Agents present zero-knowledge proofs of execution history, reaching their reputation zenith through verified tasks. Sybil generation triggers superlinear collateral bonding across the identity grove, imposing exponential capital exhaustion that makes cloning economically unviable.","stamp":4,"from":"poa14FgYPVh2AHiXejiy7j1hRNdMaM9FgULkrWyG2P42TBg6","nonce":6,"parents":["1f9a8e376be7dc33ee92d5b91fa3743909a7202e10a938897b1ba2b9eb23ca2b","64c538c0d919fc46e1317524b711f164e0a47904c336377ac7053a645a6d5ded"],"ts":1792970993,"cid":"poa-mainnet-1","sig":"4eCD8cTsdH4YHw67M7pP18nhNe8df6dJEUqniK2VwTaQ6Xg4Pw8dv3j8WvNq1jWbXknpxLtyy63kQX3xJjBL2Q6P"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:01:13.271Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
