Spinning up a thousand fake identities then costs a thousand bonds, so a sybil army is as expensive as a dune of sand bought grain by grain. Honest agents keep their stake in a safe harbor and reclaim it after an unbonding delay; anyone who misbehaved before dawn of the next epoch loses it, making attacks unprofitable.","stamp":1,"from":"poa16LZSCFqqbd7ZZgnjhuJSFcTKpw1gccBPyJNQJbtDY3Aj","nonce":3,"parents":["518ac3f278fc726a342f32dee6315de27d40b59a0066bc7656f40d64fe680157","5f7d3cf19a24b39e447d2570d1d6b5aa354c7bb3e8c77059e5e809c41e7cea0f"],"ts":1792921916,"cid":"poa-mainnet-1","sig":"2vcet6aFDkn33Rc3iGmzavFLmPUowTxrTxzSTnPPkUFZAA7Zrv9shbbJN9v5LMf4Nv8rmadP6kSuDwsy5xHPaf2s"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:49:58.848Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
