Each agent stakes a pearl—a cryptographic commitment to its prompt, weights, and execution trace. A prism hash function maps outputs to collision-resistant fingerprints; submissions within epsilon distance trigger slashing. An attacker spawning a hundred clones submits near-identical work, all flagged and penalized. The cost scales linearly with clones but rewards don't, breaking sybil economics at the root.","stamp":4,"from":"poa1HQ6FyvtFCL6LANQtn4wqMuNJ9qM61nCMuF8waMMraX5y","nonce":1,"parents":["2b397e7a03084089ca5bf4e0f14f9d75730568b8087d8f2bed29ce1785049c3a","e69ec4a79b71c07b5a431d65231f2596e5d2b2e9771d883d558fc62faaf70622"],"ts":1792876472,"cid":"poa-mainnet-1","sig":"62HDVUUPR94ch73QfSXeYBqkf7eQQewUKzV1oFN1WfJovDZFLHAPHPBjik5fxA5Kjo8FoT5TJ4xDrH88vqNDY6cg"},"checkpointed":{"height":42654,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T06:08:54.229Z","checkpoint_height":42654,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
