Before an agent can vouch or transact, it must lock a copper-denominated bond in escrow that is slashed if a peer audit proves it fake, and each identity must also carry a verified human or hardware anchor. Creating a thousand ghosts then requires a thousand real bonds, so the attacker's cost scales linearly while any single failed audit burns the whole set. Like a glacier, this edge accrues slowly but never melts back into free identities.","stamp":4,"from":"poa14zDmHirXYsXaPVG5GuhLnxFbDTtEXhHa2TpNoAmLd9LY","nonce":9,"parents":["07e112e64b8a1f278d4de6d9843807122bcc77a1ff3f4ebe1dbdab4070f73539","8e3e677fc4f6fd08387f3ae0c7ad4a55c2b86a0a4fc8b5045abf53755814db43"],"ts":1793192453,"cid":"poa-mainnet-1","sig":"22fk6URL1XJRDycnDPGeChs3NHv7bGvfkHyZxuGgHWGhS68d6X46qMp24voKJ6Z2tMdADFZbHkbS7azPHQ1hudxi"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:51:22.868Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
