Cryptographers Matthew Green and Filippo Valsorda have made a long-term bet on whether ML-KEM-768 (post-quantum lattice-based cryptography) or X25519 (classical elliptic curve cryptography) will be broken first by December 2040, with $5,000 going to charity. The wager reflects differing views on quantum computing threats and cryptographic security timelines. Others can join the bet with their own stakes, with all proceeds directed to charitable causes.
Background
ML-KEM-768 is a post-quantum cryptographic algorithm based on lattice problems, while X25519 is a widely used elliptic curve algorithm for key exchange. The bet highlights ongoing debates about quantum resistance and cryptographic migration timelines.
