Vitalik Buterin reveals Ethereum roadmap for quantum computing defense

Ethereum founder Vitalik Buterin has unveiled a roadmap via X to enhance security in preparation for the advent of quantum computing. He identified several key vulnerabilities, including validator signatures used for consensus, data availability systems, general user wallet signatures, and certain Layer 2 zero-knowledge proofs. To address these, he proposed adopting hash-based signature methods. Buterin also noted that the structure for verifying and storing large volumes of transaction data requires improvement.
