A report on quantum computing and cryptocurrencies concludes that the main risk lies in the public-key cryptography protecting wallets, while blockchains themselves remain secure because they rely on hash functions. The authors say the warning applies more broadly to other systems that depend on public-key encryption, as quantum advances could eventually break widely used cryptographic methods.

Why now: Quantum computing progress is raising concern about the long-term security of current encryption standards.
