The Quantum Computing Revolution: Implications for Bitcoin
The once unimaginable concept of quantum computers is now a hot topic at cryptocurrency events, shedding its science-fiction aura. At a recent developer conference, ETH Denver, experts and security researchers delved into a pivotal question: what is the fate of Bitcoin if an advanced quantum computer becomes a reality?

Recent reports suggest that new proposals are being integrated into the network’s enhancement strategy, establishing preliminary defenses to preempt potential crises.
Understanding Quantum Computing: Hashing vs. Signatures
Hashing: A Lesser Concern
While hashing—a crucial component used by miners and various system parts—experiences only a minor boost from quantum computing, this isn’t the primary concern. As per Lov Grover’s quantum search method, hashing experiences a square-root speedup, affecting safety margins but not eliminating them entirely. Essentially, cracking hashes on a large scale would require extraordinarily large and perhaps impractical machines based on current models.
The Real Threat: Vulnerability of Signatures
According to reports, the primary concern lies with digital signatures. “Our primary worry in the coming five years revolves around signatures, as highlighted by Shor’s algorithm,” noted Hunter Beast, a co-author of BIP 360, during the ETH Denver event. Most wallets today rely on elliptic curve cryptography, which Peter Shor demonstrated could be unraveled by a quantum computer, potentially exposing private keys from public ones if the appropriate hardware emerges. A blockchain security company has been monitoring addresses that have already revealed their public keys, and the numbers are significant. Project Eleven, a blockchain cybersecurity firm, has flagged millions of coins that could be at risk if an attacker had access to a sufficiently large quantum device.
Progress in Quantum Computing: How Close Are We?
Estimations regarding the resources required for quantum computing breakthroughs have evolved. While older studies estimated the need for millions of qubits, recent research from organizations like Iceberg Quantum suggests the necessity might be in the six-figure range. However, the number of raw qubits is just one aspect; the critical factors include the number of “logical” qubits operable with low error rates, the duration of calculations, and the machine’s stability during the process. Advances in error correction by major companies like Google have shown promising progress, albeit not signaling an immediate breakthrough, but altering risk assessments.
The Cryptocurrency Industry’s Preparedness
Reports indicate that teams are mobilizing to investigate and develop defenses. The Ethereum Foundation has initiated a post-quantum group, while major exchanges and companies are actively participating in these crucial conversations. Coinbase, for instance, has appointed advisors, and its CEO, Brian Armstrong, emphasized that the challenge is manageable with strategic planning, describing it as “solvable.”
