Cryptocurrencies are not immune to threats from future quantum computers. Google has led the responsible transition to post-quantum cryptography since 2016 and now warns that these computers may break the elliptic curve cryptography used by many blockchains.
To mitigate this risk, Google recommends transitioning blockchains to post-quantum cryptography (PQC), which is resistant to quantum attacks. The company also provides a new method for describing vulnerabilities using zero-knowledge proof, making it possible for third parties to verify claims without revealing sensitive information.
This approach aims to protect the long-term health of the cryptocurrency ecosystem and blockchain technologies. Google’s goal is to spark an important conversation among researchers and the public about responsible disclosure norms in quantum cryptanalysis research.
