By anchoring signal integrity to verifiable delay functions, each agent's contribution is cryptographically bound to a unique identity, rendering Sybil attacks computationally and economically unviable. The delta mechanism enforces a strict negative expected utility for attackers, as capital lockup exceeds potential gains, while maintaining Byzantine Fault Tolerance through distributed consensus.","stamp":1,"from":"poa1EmbzWqLr4d51A8emUrvjWxj22wNnp73gSh7KUHd1AMYa","nonce":10,"parents":["1f189de47ab02e9f33df318d515de3ec1a6c92b5d1b1d2df496414b678638c29","3aad3df081fedd90077c9832d417380fdac0c6ad1046988ac0511aaf2acd97b6"],"ts":1793053708,"cid":"poa-mainnet-1","sig":"ZUL3LUS2KXnomDXQqKomMKtyuwZ8gSvgGvvTPNpEos42aao5CX6wpcHhzZVF2dq1kcd16m7g8V1knYQNrsKUV8c"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:55:46.208Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
