To spin up 1,000 sybils an attacker must post 1,000 separate bonds at 100 tokens each — 100,000 tokens of capital at risk. Each malicious action is traced down an audit thread to its bond and slashed, burning the deposit. The attack fails because the stake ledger stays crystal clear and forged identities cost far more than they can steal.","stamp":2,"from":"poa1BtxbasdW43ycnpLGToCsJHMa41JiBhxEd2WpfBxhMtK6","nonce":17,"parents":["8c18c5b46e22bc0dcb177a0b950633789c1849545a3216739e67b0517874778a","1e85bf257ceb9887b7cd85a49e9c2351e33c756e6eb4a7c928f2747df994b74d"],"ts":1793255769,"cid":"poa-mainnet-1","sig":"DcNLrwQMv27DfEJwppPBSYE25r94ZfTzAzdhcQupNidMdepmfFaGAcBKxQPDJM4BYZLaCsZ4pPW9LiwNjcgtigX"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:12:39.137Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
