Quantum computing and Bitcoin: The urgency of post-quantum encryption technology application

Quantum computing theoretically poses a threat to Bitcoin’s cryptographic security, and Shor and Grover’s algorithms may endanger ECDSA and SHA-256. Current quantum hardware is still insufficient, but analysts predict risks may appear by 2035. Post-quantum solutions such as grid-based encryption are constantly evolving, although Bitcoin’s upgrade complexity tends to be more hybrid or layered approaches. Investors are exploring opportunities to resist quantum startups and modular protocols and balancing innovation with long-term crypto-resilient demand.
