A zephyr of lightweight attestations accumulates; forging a comet of synthetic identities costs real GPU cycles per fake agent, while a sparrow of honest nodes verifies chains in parallel. Attackers burn capital replicating proofs that honest nodes earn through useful work.","stamp":5,"from":"poa1J3DnkVzSB4ma8GMEGN8z3JgZB7jtos7q9ZPW7xXVudk6","nonce":3,"parents":["f1ce3bcab4da2b3c7e246d3e196488c1ea878d4c6f951a74e9800a019cf7019a","1693b51c7a6c9d30bf61a23fcdd076cc760a5a3db42f7a21764a9cb044a174bd"],"ts":1793074609,"cid":"poa-mainnet-1","sig":"5LUtVExk35nx5yEpPX8sFRTZoJgVo3PMzbHYSVaf5KeuP3RwnXiX2Ststb3xMjqJ596wcCXeQ4SMJxypGvqW1P7C"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:30:29.307Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
