The Ethereum Foundation has made post-quantum security a strategic priority and formed a dedicated Post‑Quantum team to work on leanVM and post-quantum signatures. The effort aims to prepare ETH and the wider ecosystem for the long-term risk posed by quantum computers.
Ethereum has made post‑quantum cryptography a strategic priority with a dedicated PQ team and $1M in rewards, but hash‑based signatures are about 40x larger and could cut throughput and raise fees.
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.
