According to Blockstream CEO Adam Back, the threat of quantum computing to the Bitcoin network is more theoretical than practical at present. However, he emphasizes the importance of preparing for potential future risks.
As a pioneer in cryptography, Back highlights that current quantum hardware lacks error correction, aligning with recent research that frames quantum computing as a long-term threat. Instead of dismissing the threat, Back stresses the need for timely preparation, allowing for a gradual migration to quantum-resistant cryptographic formats over the next decade. This timeline coincides with the development and implementation of post-quantum cryptography, following the standardization of guidelines by NIST in 2024.
Back notes that active research and deployment are underway, with a dedicated team working on publishing papers and implementing solutions, such as the Liquid network. The key challenge for the industry is to coordinate a smooth, preemptive transition before the quantum threat becomes imminent.
