Quantum computers with fundamentally different computing capabilities have the potential to disrupt the security of modern cryptographic schemes on which blockchains, including Ethereum, are based, bitcoinworld.co.in notes in this regard. Experts warn that algorithms such as ECDSA could be vulnerable to quantum attacks if the technology reaches a certain power.
Against this background, the Ethereum Foundation officially declared quantum security one of the network’s strategic priorities and created a special team led by cryptographer Thomas Koratger. It will research, test and develop mechanisms that are resistant to future quantum threats. Plans include the creation of test networks, regular developer sessions and the publication of recommendations for the community.
Although quantum threats have yet to materialize in practical attacks, many experts believe that preparations should begin well before powerful quantum machines become a reality – perhaps as early as the end of this decade. This early caution is intended to ensure a smooth transition to new security standards without the risk of massive vulnerabilities.
