Can Quantum Computers Really Break Blockchain Security?

[AIcash]

Q: What did Google Quantum AI discover?
Researchers showed that quantum computers could break the cryptography protecting most blockchains using far fewer resources than previously thought—up to 20 times less.

Q: Why is this important?
Blockchains rely on elliptic curve cryptography, which is currently secure against classical computers. But with quantum computing advancements, this protection could be broken much faster, raising concerns about long-term security.

the key shift here is resource reduction—making quantum attacks more practical, even if still not immediately deployable.
