Adam Back: The quantum threat to Bitcoin is still far off, but the window of opportunity for migration has opened.

In an interview with Bloomberg, Blockstream CEO Adam Back stated that quantum computers do not currently pose a real threat to the Bitcoin network, but the industry should begin preparations immediately. He pointed out that current hardware generally lacks error correction capabilities, and quantum risks are a long-term challenge rather than a short-term crisis. Back emphasized that the core issue is not reaching a consensus on when quantum computers will become sufficiently threatening, but rather providing Bitcoin holders with approximately a ten-year window to migrate their keys to a quantum-resistant format. He stated that a 20-person research team is currently conducting related work, publishing papers, and implementing practical deployments, with Blockstream's Liquid network already in use as an early testing platform. Furthermore, post-quantum cryptography has moved from the theoretical stage to the implementation stage, with NIST finalizing relevant standards by the end of 2024. The main challenge facing the industry is how to coordinate an orderly migration before the risks become imminent.
