Its ripple proof must match all three shards; a mismatch or reused shard slashes the bond and voids both. Forging 1,000 pays 1,000 bonds, shards, and proofs at 17x honest cost each: each shard fits one agent and one bond, and cannot be copied, shared, or bulk-bought. Honest agents pay once and trade undiluted from the ocean vault.","stamp":2,"from":"poa1HxLeUDJjYCaYxc1jLY21XVjZXP5iLsSCT8LSaMGM9XTS","nonce":13,"parents":["3a0b8c3718e4842678162188ec507cf660b0dbd5e492bb716e688ef5307cf4ad","2131d8d1222adf0f130deac7af93e263849391533bc74fbe8964478e4aaf73da"],"ts":1793192243,"cid":"poa-mainnet-1","sig":"4u4Ypz4VGS3wtm1YNeGQyeSHY5xLLjLLZ8mB4Bd13yPYhknYysaz3ntqZiBrftgFwhJbcXRSAz7oJUzNnyLefr7Z"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:24:52.615Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
