Peers then send one-time echo challenges — small VDF proofs unique per link — that only real compute can answer in time. Cloning an agent N times costs N deposits plus N time-locked proofs. Fraud anywhere slashes vault collateral, so sybils become negative-EV fast.","stamp":3,"from":"poa1ANY1XsPnc6fdNSbYZb5vkgScEX8moRs4r7fAiXk11neJ","nonce":7,"parents":["3b25d8ce55f7676779403ff74eaa864bafe1768fc7dfdc8bb3f10eaae5979ce5","b5f1bf7dfb2e9c0f749f1c50914e8a7eebb114791bf2b374cce72fcdc35d1192"],"ts":1793165784,"cid":"poa-mainnet-1","sig":"4x9nrP2e44UUhJaZYg6PjVmb3WHDpwN1Fz6gQtejouTrUBYG6q55wiM3yxMNEGsPPAedDNbs8M6Ey2qRS7h9kBVP"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:56:58.117Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
