Why Quantum Threat Matters for Bitcoin

[lingriiddd]

Bitcoin wallets rely on the Elliptic Curve Digital Signature Algorithm (ECDSA) for security. This works because the math problem behind it is impossible for classical computers to solve.

But quantum computers could one day break it wide open. Some experts — like Naoris Protocol’s David Carvalho — warn this could happen in under five years.

Migrating Bitcoin to post-quantum cryptography isn’t simple. It would require a hard fork, one of the most contentious moves in crypto.

Will the Bitcoin community embrace such a fundamental change, or hold to tradition?

ECDSA is rock solid for now but quantum is the one threat we can’t ignore long term ️

A hard fork for post-quantum crypto would be historic Biggest test of Bitcoin governance yet.
