The Latest Quantum Computing Claims

Recent discussions regarding the quantum threat to Bitcoin quickly gained traction but were promptly challenged by Adam Back, a pioneering figure in the cryptocurrency's early days. He refuted suggestions made by Bitcoin commentator Charles Edwards that Bitcoin's value should be lowered by 30% in anticipation of a significant quantum breakthrough expected within three years.

The Basis of the Quantum Threat Argument

Edwards argues that Bitcoin could be compromised by quantum computing advancements, suggesting that immediate price adjustments are warranted based on expert opinions and projected technological timelines. Specifically, he states that elliptic curve cryptography could fail by 2028, leaving no time for Bitcoin to devise a response.

Back's Counterarguments

Back strongly disagrees with this assessment. He points out that Bitcoin operates differently than traditional banks; it utilizes digital signatures instead of standard encryption practices. Furthermore, solutions for post-quantum signatures are already in place. The National Institute of Standards and Technology (NIST) completed its SLH-DSA process in 2024, enabling Bitcoin to easily transition to quantum-secure signatures without the need to lock funds or overhaul its entire protocol.

The Reality of Quantum Readiness

Back has reiterated that the concept of quantum readiness involves manageable software upgrades rather than an urgent, catastrophic scenario. Current developments like Taproot, scripting enhancements, and adaptable signature standards facilitate a gradual transition well before any significant quantum threat emerges.

The Bigger Picture

Back believes that, even under optimistic projections, large-scale quantum computing capable of disrupting Bitcoin is still years away. In such a scenario, sectors like banking, government operations, and global internet security would be under pressure first, not just Bitcoin investors.

He emphasizes that the key issue is not to dismiss quantum research but to avoid exaggerating urgency. Bitcoin has ample time, resources, and a history of successfully implementing cryptographic improvements. Treating speculative quantum threats as immediate concerns merely reflects a focus on short-term trading rather than the genuine risks that the protocol might face.
