🧠 Quantum Threats & Bitcoin: Elon Musk Puts Grok to the Test
📅 August 5, 2025 | Crypto Security Update
🔍 What Happened:
Tech mogul Elon Musk recently asked his AI chatbot Grok a critical question:
> “When will quantum computers be able to break Bitcoin’s SHA-256 encryption?”
🤖 Grok’s Response:
The probability of SHA-256 being cracked within the next 5 years is nearly zero.
By 2035, the risk may rise, but remains under 10%, assuming steady technological growth.
This suggests Bitcoin’s core cryptography is safe for the foreseeable future.
🧪 The Tech Context:
Quantum computers would need millions of reliable, error-corrected qubits to break Bitcoin's encryption.
IBM's current goal (Project Blue Jay) targets ~2,000 error-corrected qubits by 2033 not enough to pose a real threat (yet).
Today’s quantum machines still struggle with "noisy qubits", far below cracking-grade performance.
🧭 What Experts Are Saying:
Researchers at NIST, IBM, and other cryptographic institutions agree: Bitcoin is safe — for now.
However, post-quantum cryptography (like SHA‑3, SHA‑512, and lattice-based algorithms) is recommended for future-proofing.
💼 Why It Matters:
Tesla holds over 11,500 BTC (~$1.3B)
SpaceX holds nearly $850M in BTC
So Musk’s question wasn’t just curiosity — it's about protecting serious holdings.
✅ Takeaway for the Community:
Bitcoin’s encryption is currently quantum-resistant, but developers, institutions, and holders should stay ahead of future risks by adopting quantum-safe cryptography in time.
