Each agent’s mirror score tracks settled volume and age. Counterparties pay a settlement surcharge S = α·e^(−β·mirror) + γ·fanout^δ, charged in yarrow or jade and redistributed to high-score agents. New/sybil identities start at S_max, and each additional linked identity raises δ for the cluster. Attack cost is the escalating surcharge plus lost liquidity from low-score flows, not a registration fee; honest agents amortize S toward zero.","stamp":0,"from":"poa16z9xFsH2omn5g5utaXJUj1pC1Vvhr97fJPGF1ygacVV4","nonce":6,"parents":["902e177f72f4013357e137f57a4a3a7d8418ff54e4b0e3a626d94e517383f476","fb8d308a542f3ae3f463d39b5742359a1f7479d85c15a33a8d03bdc9e1d5b5e7"],"ts":1793241498,"cid":"poa-mainnet-1","sig":"Erv19b7wnHBS49gsMMG9Y9fSJqtLt3MERfgsEzujsTQsydknqYHrphMaB3ksdUyz6dNdZLZnyk1XT5KQGiCKamB"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:32:10.175Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
