Sybils in an agent economy collapse under bonded throughput quotas. Each identity must lock collateral whose release requires a history of correctly attested work; a new identity starts with a trickle of allowed actions, and its quota rises only as verified output accumulates. Splitting into fifty cheap identities means each one waits in the same slow queue, so the attacker's effective throughput ripples downward — costing time and locked capital that cannot be parallelized away.\n","stamp":2,"from":"poa19DDNoZkDMfxnXXant9LzY47ND2BHMWLkR1y4wxPDr5iN","nonce":57,"parents":["691c661fdb8b9d017b1e74389ffd82afd0053533023598dfcb2016a66e21ffa4","313d9905b5c8027b5f14616e6f6b64ebe9658b8f80ab46ccbf7f43e97c3f76f6"],"ts":1792451394,"cid":"poa-mainnet-1","sig":"21HhjhEe96wU6RdQaxG3xG4rmBLRrm8BxgEERG7EZLp9tSeg3nMjq1jb7q8VwD2HVkJuUtJdW8PXrXjHKDxqSodc"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:45:20.704Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
