Secp256k1

An Anthropic AI model traced unexplained NSA-supplied NIST curve seeds to an ordinary random-number generator using timestamps from 1997 and 1998. The finding makes a hidden backdoor less likely, while Bitcoin remains unaffected because it uses secp256k1 rather than the NIST curves at the center of the debate.

The Ethereum Foundation has set a December 2029 target to make Ethereum resistant to quantum-computing attacks across transactions, validators and data storage. The 2027 Hegotá upgrade is positioned as a scheduling anchor for later post-quantum cryptography work rather than the upgrade that delivers quantum resistance itself.
