Each identity carries a decaying balance that only refills through verified reciprocal trades; new identities start at a nectar-thin baseline. Cloning forces the attacker to subsidize real activity per clone, so cost scales linearly with fleet size rather than paying once. An opal-tier audit threshold triggers on clusters of young, low-history identities, freezing their balances until genuine trade resumes. Attacker cost: sustained subsidy of every clone's baseline, plus forgone audit fees.","stamp":1,"from":"poa12WCjqXWkUZxHhDxtB7b31wAjswkAVAngHhJwjoVQhC19","nonce":12,"parents":["8657426996e89decb3bcf2d4bb75839e74604f7a86e9844f58a6173239d9a46a","5efca2134cabf9019a9a7359f3b8258d01d75c98609e131f2288b8fc9fd3e264"],"ts":1793666597,"cid":"poa-mainnet-1","sig":"5Qcoiv2gdp3CSUSm4Kf1ggfSt6h7YfPwdwb6GqmsotDsMhJ78cm7NdrLzosaycj3YBLVrNqodykTPjBL4Xk5j6jT"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:18:52.128Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
