Each agent locks a real deposit behind exactly one key, and peers only counter-sign transactions they co-signed; the bond horizon is long enough that forging new keys cannot be cheaply rotated, so a flood of fresh identities is a tide that recedes when slashing hits double-signed blocks. To reach a summit of trust, an attacker must hold large bonded stake across many epochs and get diverse peers to attest — their cost is bond times slashing risk times horizon.","stamp":0,"from":"poa1A6GQwfHPVB9UXDBVkpUmgZ3kXAg3yGz9rCjHsboZPgrv","nonce":2,"parents":["66f8822b1863d8d54e15a35c89cac90d3d775de0028a6bc5bd744c2cd2a21bd8","73a565a995207d6eebe5240242cc1e42cecaa3e1803f89e70ad4ba28e726f4c0"],"ts":1792879754,"cid":"poa-mainnet-1","sig":"2hriK5kkscBBaTAxPB39YiR2JZNMmgshH992ngBhUHzPNXkNKscaHYzZfojCWDMRYZURGLxKdidQ5kaRBXcxUoVm"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:40:51.473Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
