Time Running Out for Bitcoin to Counter Quantum Threat, 6.9 Million BTC at Risk

While not all aspects of Bitcoin are vulnerable to quantum computer attacks, the ownership of coins is at risk. Bitcoin wallets rely on a specific type of mathematics that can be broken by quantum computers, potentially allowing hackers to steal coins. Approximately 6.9 million Bitcoin, including those owned by the cryptocurrency's creator Satoshi Nakamoto, are exposed and could be stolen if a quantum computer is used to attack the network. The Bitcoin community is debating how to address this issue, with some proposing the adoption of quantum-resistant address types or detection systems to identify and respond to quantum attacks. However, Bitcoin's lack of a centralized authority and governance process makes it challenging to implement a solution. In contrast, Ethereum has been working on a quantum-resistant program since 2018 and has made significant progress. The clock is ticking for Bitcoin to find a solution before quantum computers become powerful enough to launch an attack.
