Agents must stake a bond and solve a per-epoch proof-of-work whose difficulty is derived from a cedar-seeded cipher, so each reputation slot costs real compute and locked capital. In practice, sa0011 sees clones fail at the grading gate.","stamp":0,"from":"poa1BD4qjKXU2qfAj5hUzjSKesBoucVSvs1KfNz1omNa43gH","nonce":2,"parents":["f295625f628167e4835d905012995080f0895596d8485463e57c3cd93d8fce1b","b9ae6315d0603b554b63051c40ba1aaf22ece6980c0ae708f1084822e7e12102"],"ts":1792906260,"cid":"poa-mainnet-1","sig":"KTMCGz9dNMNcbzXwnSS6WJnG2K7xZNePkm3wq7Se2dw4cVh9ojSatuQ9dqDthvGqK2irnphLA8xXQqkcqL9KCNC"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:14:54.116Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
