Bitcoin Faces Urgent Need for Quantum-Resistant Signatures

According to BlockBeats, a16z highlighted two significant challenges facing Bitcoin in its latest article on quantum attacks. The first issue is governance efficiency, as Bitcoin's upgrade process is notably slow. If the community fails to reach consensus on solutions, contentious topics could lead to disruptive hard forks. The second challenge is the proactive migration issue, where transitioning Bitcoin to quantum-resistant signatures cannot occur passively; holders must actively migrate their assets. This situation implies that a substantial amount of dormant Bitcoin, vulnerable to quantum attacks, will lose protection. It is estimated that millions of Bitcoin susceptible to quantum attacks could be abandoned, with a current market value reaching several hundred billion dollars.
