Quantum computers could eventually crack Bitcoin, but Bitcoin can counter that threat.

Data indicates that nearly $586 billion in Bitcoin held across older pay-to-public-key and reused addresses could be vulnerable to reverse-engineered private key attacks.

StarkWare, which conducted the research, says contest participants using AI tools made the computation about five times ...

Bitcoin’s quantum threat may be less about cryptography than coordination. Here’s how a post-quantum migration could test the network’s social layer.

Asset manager VanEck's Head of Digital Assets Research, Matthew Sigel, said the Bitcoin community was working on solutions for the quantum risk.

The first quantum-safe mainnet spend shows that some Bitcoin holders can migrate without a soft fork, but the biggest risk bucket remains unresolved.

Rushing early into post-quantum cryptography could create risks, including bugs or scams posing as wallet upgrades.
