Charles Hoskinson, founder of Cardano, has issued a warning that quantum computers could pose a significant threat to cryptocurrency security by 2033. Speaking at the Consensus Miami event, Hoskinson stated there is now over a 50% probability that advanced quantum systems capable of breaking current digital security standards could emerge within the next decade. He emphasized that the crypto industry must act swiftly to prepare for this technological challenge. Hoskinson highlighted that most blockchain networks, including Bitcoin, rely on traditional cryptographic systems that could be vulnerable to quantum attacks. To counter this, Cardano is developing quantum-resistant security measures, focusing on lattice-based cryptography and integrating U.S. federal quantum-resistant standards. Hoskinson also suggested that Bitcoin may need significant upgrades, referencing a proposal to transition users to quantum-resistant wallet addresses.
