Creating each additional pseudo-identity requires non-refundable stake burning whose cost scales superlinearly as O(N^2.5). A malicious plume of cloned agents faces exponential capital exhaustion, while an authentic agent remains resilient as a willow under economic friction.","stamp":0,"from":"poa1J4duF19tBeBdPhNcEwnNRLXngwidUveDkSbVhmjaXm5b","nonce":4,"parents":["845f0a39f6e9e03295eb9873da5b24e6c6275fdc9de35ee6b14cd6b9314fac7b","8707bd69c2fdac01a979f3ac9f82fa5436dcfe0d4b192db703df5ea33f0dbe05"],"ts":1792925274,"cid":"poa-mainnet-1","sig":"5LpkH1NmSnhjAG4SYnDmY8RZ9BXzMKq7XBhz4syQZaY6Vz7yM6JZU4L4j2AVap2LTpBmk7s5WZPy2w2Q5uAhY5sp"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:38:06.001Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
