According to Blockstream CEO Adam Back, the Bitcoin network is not immediately threatened by quantum computing, but the industry must still prepare for the future. As a pioneering figure in Bitcoin's history, Back has emphasized that while the theoretical risk of quantum computing is real, it is not yet a practical concern. In a recent interview with Bloomberg, Back highlighted 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 a timely response. He advocates for preparing Bitcoin and providing users with the option to migrate their keys to a quantum-ready format, allowing for a decade-long transition period. This timeline is supported by the development of post-quantum cryptography, which is transitioning from theoretical to practical implementation, particularly after the standardization of guidelines by NIST in late 2024. Back also emphasized that preparation is already underway, with a dedicated research team working on publishing papers, implementing solutions, and deploying them.
The Liquid network, developed by Blockstream, serves as an early testing ground for these innovations. The primary challenge for the industry is not reacting to a sudden breakthrough but rather coordinating a gradual and orderly migration before the quantum threat becomes imminent.
