PANews reported on April 21 that an independent advisory committee commissioned by Coinbase released a 50- page report stating that while current quantum computing power is insufficient to break the encryption algorithms used by blockchains such as Bitcoin and Ethereum , the likelihood of "fault-tolerant large-scale quantum computers" emerging in the future is increasing, and the industry needs to plan its response path immediately. The report points out that NIST recommends migrating to quantum-resistant encryption schemes by 2035 , but this timeline may be overly optimistic. The Ethereum Foundation has proposed quantum-resistant digital signature schemes, and Solana and others are testing quantum-resistant wallet designs. The report states that while post-quantum cryptography exists and is being standardized, issues such as increased signature size, block sizes potentially increasing by up to approximately 38 times, wallet migration, and handling of lost funds will make large-scale switching complex and costly. The report recommends using hybrid schemes and incremental upgrade mechanisms to allow for rapid switching in the future.
