Quantum Computing Could Threaten More Than Bitcoin Wallets

Advances in quantum computing may pose risks not just to Bitcoin wallet security, but also to the network’s underlying economic model, according to David Duong, head of investment research at Coinbase. While much of the discussion has focused on private key theft, Duong argues that quantum machines could eventually disrupt Bitcoin’s proof-of-work system itself.

Bitcoin relies on two cryptographic pillars: ECDSA for transaction signatures and SHA-256 for mining. Quantum computers running algorithms like Shor’s and Grover’s could theoretically weaken both, enabling faster block mining and undermining the balance that keeps Bitcoin decentralized and secure.

this feels like a “not today but definitely someday” problem ppl don’t wanna think about
