According to Blockstream CEO Adam Back, the threat of quantum computing to the Bitcoin network is more of a long-term concern than an immediate danger. With a background in cryptography dating back to the 1990s, Back emphasized the importance of preparation in an interview with Bloomberg.
He noted that current quantum hardware lacks error correction, aligning with recent research that frames quantum computing as a long-term risk. Back's primary concern is not dismissing the threat but rather ensuring a timely response. He suggested that preparing Bitcoin for a potential quantum threat and giving users the option to migrate to quantum-resistant keys over the next decade is a prudent approach.
This timeline is supported by the development of post-quantum cryptography, which is transitioning from theoretical to practical implementation following the standardization by NIST in 2024. Back highlighted that active research and deployment are already underway across the ecosystem, citing a dedicated 20-person research team and the Liquid network as an early testing ground. The industry's challenge lies in coordinating a gradual and orderly migration before the quantum threat becomes pressing.
