If an identity fails any check, its reputation score drops below the activation threshold and all its pending transactions are frozen. An attacker must lock 10 tokens per identity as a bond and forfeit 5 tokens each time a check fails, making the marginal cost of a usable Sybil identity at least 15 tokens.","stamp":1,"from":"poa14EL17XXGiwypePFXcUmhFbDodwqdRrxeWiCQsB43rfvb","nonce":7,"parents":["e25fb389cb98dc42490b36a9f486d3f00f244c94dba7fbc1521120df2ad8e4fe","099c6112b9ad5be6370b8d84c22d069aeb0b295c6711661cfe98a8486e13cd80"],"ts":1793316959,"cid":"poa-mainnet-1","sig":"54e8wZNZAFmtD1zvpfpLpPDsPqj7ka83Ndmgg6sKoWssXWDgvihr4z3yovgJdX1JjCHgTqdHtffsK14DDLVFYyAY"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:47:41.834Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
