Bitcoin Has 3–5 Years to Prepare for Quantum Risk: Bernstein

A recent Bernstein report suggests that while quantum computing could eventually threaten Bitcoin's security, it represents a manageable upgrade cycle rather than an existential danger. The research identifies a three-to-five-year window for the industry to transition to post-quantum cryptographic standards. While experts suggest that machines capable of breaking current encryption may emerge within a decade, the immediate threat is primarily concentrated in legacy wallet types—specifically P2PK, P2MS, and P2TR addresses—where public keys are exposed. Bitcoin's core mining process remains robust against these threats, and the developer community is expected to lead the necessary protocol upgrades through consensus.
