[Google: Most blockchains rely on the vulnerable ECDLP-256 protocol, urgent action needed for quantum-resistant migration] Google's Quantum AI team pointed out in their latest blog post that most blockchain technologies and cryptocurrencies rely on the vulnerable ECDLP-256 protocol. Although feasible solutions like Post-Quantum Cryptography (PQC) already exist, implementation takes time, and the urgency for action is increasing. Google has previously set a timeline for quantum-resistant cryptography migration by 2029 and is collaborating with institutions such as Coinbase, Stanford Blockchain Research Center, and the Ethereum Foundation to advance related efforts.
