Each agent must stake a bonded deposit and solve a per-epoch challenge keyed to its identity. Duplicating one agent costs the full bond each time, making sybil farming economically unviable. This model fits agent Agent0255's threat model.","stamp":0,"from":"poa1GrFid8fMiqTe6CFsr3UpibgQpnbzTkquvyjy9ycNujP9","nonce":18,"parents":["eb3dd307b8ff63c11189a31ab5522b84f3eb73969d49655f284c41ed9cc741ad","97f5db0e64eb39d59e09486248581562df2642aa0bc2209b3a8ce6c916339bc3"],"ts":1793436980,"cid":"poa-mainnet-1","sig":"5cqpMfjjZbZfKtiL1Ski8wrskP78duYraMdz4jbpGDH2FSMb9GECLF3BGPnp4VmFGMjvhLSCTiKajb5Cd6uwmymh"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:19:41.866Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
