Quantum computing poses a future threat to Bitcoin security by potentially breaking elliptic-curve cryptography, but the industry is advancing quantum-safe transaction methods, protocol upgrades, and custody protections to mitigate risks. These developments reduce costs and prepare the ecosystem despite the uncertain and distant timeline for quantum computers capable of such attacks.
This Wire brief sits within Fusion42's coverage of Quantum Computing and Crypto & Web3.
◆ ◆ The Wire takeaway
You must start embedding quantum-resistant cryptography in your product roadmap as the cost of these defenses drops and protocol upgrades gain traction. Your custody solutions need quantum-safe features to stay credible before quantum computing becomes a real threat.
