Galaxy Research Chief Warns: Quantum Computing Could Threaten Bitcoin

Galaxy Research Chief Warns: Quantum Computing Could Threaten Bitcoin

Galaxy Digital's Head of Research, Alex Thorn, has issued a stark warning about the threat that quantum computing poses to Bitcoin, suggesting the crypto industry may not be taking the risk seriously enough.

In a recent post on social media, Thorn stated plainly: "Quantum computing is a bigger threat to Bitcoin than many think."

While advancements in quantum computing still appear to be years away from practical implementation, the potential consequences for blockchain security — particularly Bitcoin’s — are severe. Bitcoin's security model relies heavily on cryptographic techniques like ECDSA (Elliptic Curve Digital Signature Algorithm), which secures wallets and transactions.

However, these algorithms, which are currently secure against classical computing methods, could be vulnerable to quantum attacks using Shor’s algorithm — a quantum method capable of breaking cryptographic keys.

If a sufficiently powerful quantum computer were developed, it could theoretically reverse engineer private keys from public Bitcoin addresses. This would allow malicious actors to forge signatures and spend BTC that doesn’t belong to them — completely undermining the integrity of the blockchain.

The crypto community has discussed the need for “quantum-resistant” algorithms, but progress has been slow and the topic often brushed aside.

As Alex Thorn's warning indicates, more investment and innovation in post-quantum cryptography is urgently needed to prevent Bitcoin from eventually facing unprecedented security vulnerabilities.

The big takeaway? Bitcoin's long-term survival may hinge on how soon the industry starts preparing for the quantum era — not just with hype, but with actionable defense strategies.
