Nicolas Consigny, leader of the Kohaku initiative at the Ethereum Foundation, has unveiled a new strategy to enhance account security against potential quantum computer threats. This approach, named SPHINCS-, aims to protect wallets without necessitating a hard fork.
Ethereum can already start preparing accounts for a post quantum world, without waiting for a hard fork.
Today, it would be just 0.07$.
The implementation of this protective measure is estimated to cost around $0.07, utilizing the SPHINCS+ signature standard from the U.S. National Institute of Standards and Technology (NIST). Consigny has modified the algorithm for compatibility with the Ethereum platform, ensuring that no protocol changes are needed. This serves as a temporary solution until the development of leanSPHINCS, which will offer further enhancements and cost reductions through data compression.
This initiative is aimed at mitigating the vulnerabilities linked to the elliptic curve digital signature algorithm that Ethereum currently employs. Concerns about quantum computing's potential to compromise traditional cryptographic methods have escalated, particularly following an experiment in April by Giancarlo Lelli, who successfully decrypted a 15-bit key using a quantum computer.
