Benchmark: Quantum computing threat to crypto is decades away

U.S. investment bank Benchmark has analyzed that the threat of quantum computing to cryptocurrencies is a problem for decades in the future and that fears of it being fatal to Bitcoin are exaggerated. According to The Block, Benchmark analyst Mark Palmer stated in a research note that while Bitcoin's security structure is theoretically vulnerable to quantum computing, a significant amount of time will be required before an actual attack is feasible. He added that the Bitcoin network will have sufficient time to implement countermeasures. Palmer explained that while cryptographic technology is used for Bitcoin wallets and transaction authentication, a limited risk exists only for addresses where the public key has already been exposed, meaning the entire Bitcoin supply is not a target for attack.
