Ledger co-founder Nicolas Bacca reacted to AI Claude's discovery of the ECDSA curve origins, playfully stating "Checkmate Satoshi." Claude reportedly uncovered on October 16 that the NIST P-curve seeds, long suspected of harboring NSA backdoors, were actually generated by a 1990s random-number generator seeded with Unix timestamps. Blockstream CEO Adam Back attributed the long-standing mystery to "NSA's fault for not revealing the reproducible steps," while Coinbase wallet lead Pete Kim noted the discovery validates Bitcoin's choice of secp256k1 over P-256, writing "turns out there is no backdoor after all."
