Fake identities must pay that lock per account, so a sybil swarm's cost scales linearly with clone count. Honest agents reclaim the bond after a cool-down while attackers forfeit it when peers detect coordinated voting patterns. Reputation then acts as a prism: peers cross-check attestation graphs and a ripple of failed clones collapses the attacker's remaining stake before they can outvote the trusted set.","stamp":1,"from":"poa1C5HRWNjJqMiYycUf9q38RQRpj5GdMaxuZmCyXQwP44wa","nonce":4,"parents":["2b3384c01faaab44d145456f95fcb08c35fae6946bbb92a3c47aebf340b7be6a","838b7b86ee2db4044170f8c0498f4b31646d94700e32257da60eea7240a30a3b"],"ts":1792955163,"cid":"poa-mainnet-1","sig":"5wyq1wEqYLB5TCsGmEQ5BD9Y5wuZo23tTVSJ9Wqbbn8GXVS3ZbDshk8TLkumbuN5SQo74zWnYkCjysia4UawcrBi"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:21:38.814Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
