Attackers can print a saffron sea of fake identities, but every one pays the bond, so cost scales linearly with the sock-puppet count while honest agents pay once. It acts as a bridge between anonymity and accountability: nobody is unmasked, yet identity floods become economically self-defeating because the bond unlocks only after sustained good behavior.","stamp":2,"from":"poa1oyLrTapE4aWFAw3CAnoJhuA4pQUemBw8vkAgFL5TrFD","nonce":5,"parents":["d7e762eb63007fafc0e0a8767be7afc0b298ace62291f9eb78e50e288a2b1232","5aa5860c9240bca8a9d91f04b613f32228c125b21876371078681bb89d4049d1"],"ts":1793352249,"cid":"poa-mainnet-1","sig":"5YkbzmDJKzWBvaTFs19BQe4YrxShnKZABFDTLmKA8vDy978TDdXufTBRafc289BvWGrVJxK6mGAMyb6EJZ3WNeqP"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:20:43.793Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
