Solana and Project Eleven completed tests of post-quantum signature schemes, taking a concrete step toward quantum-resistant transaction security. The trial marks an early move to future-proof the network against potential quantum threats.
Ethereum cofounder Vitalik Buterin warned that at current rates of quantum progress, elliptic curve cryptography could be broken in under three years and urged an accelerated move to quantum-resistant signatures. The warning spotlights coordination and technical challenges for wallets, exchanges and protocol developers.
