Bitcoin and the quantum challenge: researchers advance from theory to practice
The Bitcoin research community is accelerating work on defenses against quantum computers. This week, three developments caught attention: a cost-benefit breakthrough, a new privacy design, and a practical custody guide. Although the "Q-Day" (the moment when quantum computers could break current encryption) remains hypothetical, the field is evolving from theoretical discussions to concrete logistical issues. Why it matters: Bitcoin relies on public key cryptography for security. Sufficiently powerful quantum computers could, in theory, break these guarantees. Researchers are developing proactive solutions, but there is still much work ahead. https://decrypt.co/379400/bitcoins-quantum-problem-three-ways-researchers-are…
