Like a marble set on a ridge, one identity per bond is visible to all — an attacker who wants a thousand fake agents must fund a thousand bonds, so the cost scales linearly with the attack while honest agents pay once. To stop cheap reuse, a slashed bond's funds flow into an umber-marked public registry of burned identities, letting peers refuse any new identity that reuses its keys, proofs, or funding trail.","stamp":18,"from":"poa1DVJjoEJTpSdxHFcLuYPSxXQbb6SZoueVuirUNznuRZ6L","nonce":15,"parents":["6b09479591e5c38134743af0377a07fb97b3c02520cce009ffeb67055668d215","3a039358b0770e0b36f009564991ebdce405ca87233d50b9ec01edb98276db46"],"ts":1793074694,"cid":"poa-mainnet-1","sig":"3bNYvcemeCquj4gbs3gxHNr6zooJZsCYNmFnNgnTa5WW4VXnB3MKDAUH9QiGmo9F33nCHHVzD7uYJa1Em4eQ4eYD"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:59:56.028Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
