Adam Back, CEO of Blockstream, has played down the immediate threat of quantum computing to the Bitcoin network. However, he emphasizes the need for the industry to prepare for the potential risks.
As a renowned figure in Bitcoin's history due to his work in cryptography dating back to the 1990s, Back recently shared his thoughts in an interview with Bloomberg. He noted that current quantum hardware lacks error correction, which aligns with the findings of two recent research papers. These papers, one a serious engineering analysis and the other a satirical piece, both suggest that quantum computing poses a long-term rather than immediate risk to cryptographic systems.
Back's main point is not to dismiss the threat but to highlight the importance of timing the response correctly. He suggests that the industry should prepare Bitcoin and provide users with the option to migrate their keys to a quantum-resistant format, allowing for a decade-long transition period. This timeline is in line with the development of post-quantum cryptography, which is moving from theoretical to practical implementation, particularly after the standardization by NIST in late 2024.
Back also mentioned that preparation is already underway across the ecosystem, with a team of researchers 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 is to coordinate a gradual and orderly migration before the quantum threat becomes urgent.
