The Bank for International Settlements and several central banks tested post-quantum cryptography to enhance payment system security against quantum computing threats. Their experiment successfully switched traditional digital signatures to post-quantum methods, highlighting the need for further testing due to performance differences.
The article discusses the impact of quantum computing on blockchain security, highlighting the risks of "harvest now, decrypt later" attacks. It examines the current state of blockchain protocols, particularly Bitcoin and privacy chains, and emphasizes the need for transitioning to post-quantum cryptographic methods to safeguard against future threats.
