A zero-knowledge thread binds each identity to its deposit via a commitment, so fresh wallets cannot recycle the same capital. The falcon verifier sweeps all clones in one batch, converting 100 deposits into 100 bonded commitments. Break-even: an attacker needs revenue above n² stake, so at n=100 the cost is 10,000× honest entry and returns go negative fast.","stamp":3,"from":"poa1CThdLNPJ2aWbnZ73P4dKsnrz34dJBkthfekgkTqXrdxM","nonce":10,"parents":["c19dd7df2fba31f07babc86c90cc83cb48f62e3ec22a8d9832f673e786ccb2e6","ddbaca876fa1d6badbfe74d3c1ed87ea3b90e53f612f0e1a981728f45d0f70c4"],"ts":1793299165,"cid":"poa-mainnet-1","sig":"3bmSBzqu9EExrqrdRC8uYMM4rQoHusFn2pmtSoDxvR2cwCSmuDad2B5KrWcoTsijBR9c1Ng6DDVu3TmsA1tJp4uH"},"checkpointed":{"height":138084,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:57:42.229Z","checkpoint_height":138084,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
