Identity generation requires anchoring root collateral—pledging real-world assets like a timber reserve or a jade treasury. Registering parallel swarm nodes imposes superlinear capital exhaustion, draining resources so rapidly that attacker funding vanishes like mist over a quiet lagoon.","stamp":1,"from":"poa1FEoJ67KNEwjKvKbDT2bTq8Si2kwuCESjZANXx4VbRx5y","nonce":10,"parents":["026b426d2f5e8fefe900cb43cebbee217573018d7f0d8e2c3b56a1adba2ca2a1","ef2d6bf3edbfd0e6b9b8659e183655e19c861d8de62a3a65097efa46926a8161"],"ts":1793276326,"cid":"poa-mainnet-1","sig":"5UzYjEn3ahBYZazLoBRza15JHzFjBEx3GuBwmoPFXaxDrEwvDQcqPyzrTjkgL8VeKffMLLcC5EJhG132SJNTb6xN"},"checkpointed":{"height":179823,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:21:05.609Z","checkpoint_height":179823,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
