Four areas to protect Ethereum from quantum attacks
Vitalik Buterin, the co-founder of the world's largest decentralized application platform Ethereum, has outlined his vision for a roadmap to protect the network from potential quantum attacks. According to him, to ensure quantum resistance for Ethereum, changes are needed in four key areas: validator signatures, data storage, user accounts and proofs.
Validator signatures: Buterin noted that the current cryptographic algorithms used to sign transactions by validators may be vulnerable to future quantum computers. Therefore, it is necessary to switch to more quantum-resistant algorithms, such as CRYSTALS-Dilithium or Falcon.
Data storage: To protect the data stored in the Ethereum blockchain, Buterin proposes using quantum-resistant hash functions, as well as considering migration to new data structures that are more efficient in terms of quantum resistance.
User accounts: The current Ethereum account model is based on ECDSA, which may become vulnerable to quantum attacks. Therefore, Buterin advises considering a transition to more secure schemes, such as BLS or CRYSTALS-Dilithium.
Proofs: To increase the quantum resistance of Ethereum, Buterin suggests using quantum-safe proof schemes, such as STARK or SNARK.
Implementing these changes will require significant effort and time, but Buterin is confident that Ethereum will be able to successfully adapt to the challenges of quantum computing in the long run.
