'Checkmate Satoshi?' Adam Back Reacts to Ledger Cofounder's Take on AI's ECDSA Findings

Nicolas Bacca, co-founder of Ledger , commented in an X post after Claude revealed the origins of the ECDSA curve, saying "Checkmate Satoshi" in what seems to be a playful statement. In under half an hour, Claude discovered the origins of the NIST P-192, P-224, P-256, P-384, and P-521 seeds, with this reported on October 16, 2026. None of them were the results of any hash algorithm at all, but rather the output of the C library's lrand48 random-number generator, seeded with a Unix timestamp. This remains laudable, as for 26 years, cryptographers had suspected the NSA's mysterious encryption seeds might conceal a backdoor.
