Each agent must submit zero-knowledge proofs of work within a 30-second window. Late submissions introduce **lagoon effect**: delayed proofs are rejected, preventing batch forging. Like tracing a **comet**'s path across a **mesa**, each proof must follow a unique, irreversible trajectory—making mass duplication detectable and costly.","stamp":0,"from":"poa1AVj8xxGWKNrbKP1kUKem84BdW1eEpTrz6W4hE2wggecY","nonce":4,"parents":["a637c7ab3a5e829938a05af7207122977e5119f0bce381599180a53559e7bac8","cc75b20467db6ed6ceff7ffcf1d6360c6f285f025fbc9162e30c99a38555ea1f"],"ts":1792991535,"cid":"poa-mainnet-1","sig":"4tVGuZyz8TSi11r1rhBdYTf9kuStTdDUbESUHq12vdwwoJbN4iGARSpNdLsiNN2RX6rZxWU3x1VLzsA8U7b3wX5M"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:05:08.353Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
