According to Blockstream CEO Adam Back, the threat of quantum computing to the Bitcoin network is more of a long-term concern rather than an immediate danger. However, he emphasizes the importance of preparing for this eventuality. As a pioneer in Bitcoin's history, known for his work in cryptography dating back to the 1990s, Back outlined his argument in a recent Bloomberg interview.
He noted that current quantum hardware lacks error correction, aligning with recent research that suggests quantum computing poses a long-term rather than near-term risk to cryptographic systems. Back's primary concern is not dismissing the threat but rather ensuring the industry responds at the right time. He advocates for preparing Bitcoin and providing users with the option to transition their keys to a quantum-resistant format over the course of a decade. This timeline coincides with the development of post-quantum cryptography, which is transitioning from theoretical to practical implementation, particularly following NIST's standardization in late 2024.
Back highlighted that preparation is already underway, with a dedicated research team working on publishing papers, implementing solutions, and deploying them. He cited Blockstream's Liquid network as an example of early adoption. The challenge for the industry lies in coordinating a gradual, orderly migration before the quantum threat becomes critical.
