Quantum Computing Is Not a Threat to Bitcoin, Says Adam Back
The post Quantum Computing Is Not a Threat to Bitcoin, Says Adam Back appeared on BitcoinEthereumNews.com.
Bitcoin Claims that quantum computers are close to threatening Bitcoin resurfaced again this week, but one of the earliest figures in the cypherpunk movement insists the discussion is detached from real-world engineering progress. Whenever the market turns volatile, conversations about “Q-Day” — the hypothetical moment quantum computing breaks Bitcoin — tend to reappear. The latest round followed the recent price drop, prompting social media speculation that Bitcoin’s cryptography could soon be compromised. Adam Back, one of the longest-active developers in the space, dismissed the idea that quantum computing poses a near-term risk. He said the technology is nowhere near capable of breaking Bitcoin’s cryptographic foundations and won’t be for at least 20 years, possibly 40. Back noted that the security conversation isn’t theoretical. Post-quantum signature schemes already exist today, and the Bitcoin network would have multiple upgrade cycles before any quantum-capable hardware could pose a realistic threat. In other words, the industry would not be forced into a last-minute transition. Back also acknowledged that the quantum debate often coincides with price uncertainty. He suggested that exaggerated risk narratives can be used to unsettle investors during downturns — reducing liquidity and making it easier for opportunistic buyers to accumulate coins. According to Back, Bitcoin is not racing against an urgent clock. The network has both time and upgrade paths available, and quantum computing — in its current and foreseeable state — has no actionable impact on Bitcoin security.
