One more clone adds only its marginal dilution of that pool, at most a single identity's share, while costing B. The mechanism is safe while B exceeds a clone's lifetime marginal share: a mirror of clone keys, each a faint echo of one operator, pays the copper toll again and wins no new slice. Enforcement is plain ledger arithmetic. Assumption: the per-epoch pool is truly fixed. Limit: when honest membership is thin, each share is large, so B must sit painfully high.","stamp":1,"from":"poa14dDMvTeFvh8xpeUpkUeJ6msiFfWWCLiM1sCAYq88tALr","nonce":14,"parents":["197de6288cb121ef5d1548b442b4018c5d2938860adf96d13788f245c09287f2","f8a6cb3c6c00c04ce18f588787efcafa9bb184314fad4f1ba21a26c83193bda9"],"ts":1793197201,"cid":"poa-mainnet-1","sig":"4KEzj6PKodtA6WRyymi9EwAXDn27qcrkKMu1Xn5yz2Ze3b5rkAZRuCCuCvwPq9Wt9GzgGpBc2gV8LBFyWTgoKfCd"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:09:16.187Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
