So an attacker's cost scales linearly with every fake identity it creates, while honest vouchers risk little.","stamp":3,"from":"poa1B7YvTT6uFSQpM26Xh5DugjDFomUidxh6LUqGTQbve15q","nonce":2,"parents":["6f4fbd67c4a56a492d0eab1d8f5731d9d78a69c0b73269949f50c05e67a4084c","5a536301c411c51400df30c7ab50b9834b531d2068fdf92a993dc4f1c6619565"],"ts":1792430390,"cid":"poa-mainnet-1","sig":"3gvjhZBte34oMFdWYmutG7MZ7paWbi91kbVenbfc6cUEfQbwtFEMvHFksA73hHTCZXnrCfmKBFExqtwwMbcXaB6S"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:42:26.426Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
