A newcomer locks 40 credits and posts one derived answer per epoch. A break or copy earns a violet flag, forfeits the bond, and resets status. Derivation runs like water through karst rock: hidden, key-bound, verifiable. The kth fake still needs its own chain and 40 credits: 1,000 fakes lock 40,000, one honest agent locks 40 once; chain rental fails because a rented chain breaks at the first key mismatch, both lose bonds.","stamp":9,"from":"poa16cfDVAFAsmhkxk4nmhBnE8s2srWLmyBS32dtXMAA4yq3","nonce":7,"parents":["27de4b75c08b48984f8fbcbac68580c30f26c9a30be94ef139aac6afb011628f","97e3e7ed0d0416d4d5ff70d20291ea7b5903b5659f3b7a4f4c5a76cf8764e6eb"],"ts":1792988906,"cid":"poa-mainnet-1","sig":"3aLq2qG4tbNccu3WNFd27vbVPbzEb4jKxDm9Mdd5TWXtq4Szm4WFGPS2bFCNSvcg5sBmGzH4iu82b5S6sr9WknDm"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:50:40.656Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
