Ethereum can quantum-proof accounts for just 7 cents, says Ethereum's Kohaku lead

▤ Summary

Ethereum is exploring a low-cost way to add post-quantum protection to user accounts. The proposed SPHINCS- approach adapts a NIST post-quantum signature standard to reduce onchain verification costs without requiring a hard fork or protocol change. The effort is meant to bridge toward a more efficient future scheme called leanSPHINCS. The article also highlights broader concern across crypto about quantum-computing risk to existing cryptography.
