Bernstein: The quantum threat to Bitcoin is real but manageable; the industry has a three-to-five-year window for quantum-resistant upgrades.

CoinFeed reported on April 9th, citing CoinDesk, that Wall Street brokerage Bernstein released a report stating that the rise of quantum computing poses a real but manageable threat to Bitcoin cryptography, with recent technological breakthroughs shortening the timeline for potential attacks. Advances by Google's quantum AI in areas such as reducing the demand for qubits mean that this risk is no longer a distant decade away, but scaling quantum systems to the level required to break widespread encryption still presents complex challenges. Analysts suggest that quantum computing should be viewed as a medium- to long-term system upgrade cycle rather than a risk. The risk is concentrated in approximately 1.7 million older "legacy" Bitcoin wallets, while the SHA hashing algorithm, upon which Bitcoin mining relies, remains secure even in advanced quantum scenarios.
