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

Ethereum's lead developer for the SPHINCS+ proposal, Kohaku, stated this week that quantum-resistant account upgrades on the Ethereum network can be implemented for as little as $0.07 per transaction. This cost-effective solution addresses the immediate need for post-quantum cryptography on the blockchain while a more permanent, integrated approach is developed. The SPHINCS+ proposal focuses on reducing the computational overhead associated with verifying post-quantum signatures, a critical step in securing accounts against future quantum computing threats. The current proposal aims to make these security enhancements accessible, ensuring that users can protect their digital assets without incurring prohibitive transaction fees. This initiative is part of Ethereum's broader strategy to maintain network security and user trust in an evolving technological landscape. The development team is actively working on further optimizations to potentially lower these costs even more.
