Quantum Computing's Implications on Bitcoin Security

By: Eva Baxter

Quantum computing is poised to become a significant disruptor in the cryptocurrency world, particularly impacting Bitcoin. The Human Rights Foundation (HRF) has emphasized the risks quantum computing poses, especially as its abilities threaten to undermine Bitcoin's cryptographic security. This emerging technology endangers Bitcoin's decentralization and overall security, potentially putting an estimated $700 billion in Bitcoin at risk.

Around 6.5 million Bitcoins could be susceptible to quantum attacks, with older and reused address types being the primary targets. The potential attack forms include 'long-range attacks', focusing on dormant keys, and 'short-range attacks' on real-time transaction vulnerabilities.

Transitioning Bitcoin to quantum-resistant algorithms presents both technological and social challenges. Transition mechanisms such as lattice-based and hash-based signature schemes require overhauls across Bitcoin's infrastructure, potentially increasing transaction data sizes and creating further scalability issues.

This situation necessitates comprehensive user education and network-wide collaboration among developers, miners, and users to preemptively counteract quantum threats. Addressing these vulnerabilities is critical for maintaining Bitcoin's resistance to censorship and ensuring its resilience against technological advancements.
