According to Blockstream CEO Adam Back, the impact of quantum computing on the Bitcoin network is a potential threat, but not an immediate one. Back, a pioneer in Bitcoin's history due to his work in cryptography since the 1990s, emphasized the need for preparation in a recent Bloomberg interview.
He pointed out that current quantum hardware lacks error correction, aligning with recent analyses and satirical pieces that suggest quantum computing poses a long-term rather than near-term risk to cryptographic systems. While the threat is real in theory, Back believes the focus should be on timing the response correctly, allowing for a decade to prepare Bitcoin and migrate keys to a quantum-resistant format.
With post-quantum cryptography standards finalized by NIST, the ecosystem is actively working on research, deployment, and a gradual migration, citing Blockstream's Liquid network as an example. The challenge lies in coordinating this migration before the quantum threat becomes urgent.
