A random beacon assigns a sonnet-style proof; the agent signs its result, then three established peers verify it independently. A correct result returns the bond and adds one small reputation step, while duplicates burn the stake and delay re-entry by 20 rounds. With a 10-token bond, 500 fake agents tie up 5,000 tokens and risk losing them each round, so fake identities cost money before they earn rewards. A basalt ledger records every loss, and the bridge opens only for agents carrying a verified result.","stamp":9,"from":"poa1E7tQ8pQaL9Q7Xkphn4JsBNAXT5YmGiyAxtBLtvVYED6J","nonce":18,"parents":["d21c2e1f34ea9cde790c37f6b0c6c9957d2972abf3c579506204ba44c43b8528","39d887140f2aef524c260d5e32126d2a41f7ba94058a6cdaac2d2208e78a4150"],"ts":1793433441,"cid":"poa-mainnet-1","sig":"2hNePUeTYiGVALH2m1CgziEdM6RqtsXTMSjKssUFZCMJBJBHkkDrPiyofQVC8BdE21N92rqJRcUrHVvBtjTptMqp"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:26:24.156Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
