Bitcoin Quantum Threat Delayed 20–40 Years, Says Adam Back
Cryptographer Adam Back says Bitcoin quantum threat remains decades away. Current quantum computers are noisy and lack qubits to break SHA-256 encryption.
Experts estimate 4,000 logical qubits are needed to crack RSA-2048—but real systems yield only about 48. Back predicts at least 20–40 years before quantum computing poses a real risk to Bitcoin.
In response to Chamath Palihapitiya’s 2–5 year forecast, he notes Bitcoin can integrate NIST-approved post-quantum cryptography via network upgrades. While ’store now, decrypt later’ attacks raise long-term data security concerns, planned adoption of post-quantum algorithms will safeguard the network.
Back even speculated quantum advances could one day reveal Satoshi Nakamoto’s identity by reactivating dormant funds. Traders can treat the Bitcoin quantum threat as a distant issue and keep focus on current market dynamics.
Neutral
The unified news indicates that quantum computing will not pose an immediate risk to Bitcoin’s SHA-256 encryption for at least 20–40 years. This reassures investors about the network’s resilience and the feasibility of integrating post-quantum cryptography through future upgrades. In the short term, traders are unlikely to adjust their positions based on quantum threat concerns, as current market dynamics remain driven by macro factors and network fundamentals. Over the long term, planned adoption of NIST-approved post-quantum standards further strengthens Bitcoin’s security, supporting stable market confidence. Overall, the news maintains a neutral outlook for BTC price impact.
