JAN3 CEO Samson Mow has dismissed concerns regarding quantum computer threats to cryptocurrency assets, particularly Bitcoin (BTC). In a quote from a paper proposing Quantum Safe Bitcoin (QSB), Mow noted that Bitcoin’s defenses against "non-existent quantum computers" have scaled at a staggering pace.
Samson Mow highlights quantum-resistant Bitcoin solutions
For clarity, some Bitcoin critics have been spreading fear, uncertainty and doubt (FUD) about the leading cryptocurrency. They claim that when powerful quantum computers arrive, they could crack the cryptography used in safeguarding Bitcoin’s transactions. Specifically, the ECDSA signatures of Bitcoin are of concern, with fears linked to Shor’s algorithm. In theory, quantum computers can break certain encryption methods. However, Mow has assured Bitcoin holders that even with quantum computers not yet in existence, the community is not idle. This is because while critics are spreading FUD about quantum computers destroying Bitcoin, researchers are already building strong defenses faster than the threat is developing.
Bitcoin defenses against non-existent quantum computers is moving along at an incredibly fast pace. There’s also the prototype from @roasbeef too.
RIP QC FUD. 🪦
— Samson Mow (@Excellion) April 10, 2026 Mow referenced various research including the QSB paper, which creates quantum-resistant transactions via a hash-to-signature puzzle. Notably, this relies on RIPEMD-160 preimage resistance instead of ECDSA. Additionally, the JAN3 CEO said the prototype released by Lighting Labs CTO Olaoluwa "Roasbeef" Osuntokun also protects Bitcoin from quantum computers. This prototype uses zk-STARK proofs to enable wallet recovery for BIP-32-derived keys in case of an emergency that might lock users out of their funds. He is suggesting that if quantum computers become a real threat someday, solutions are already being developed. "RIP QC FUD," he stated. In October 2025, the head of Capriole Investments, Charles Edwards, sounded the alarm that quantum computers might only need approximately 700 usable qubits to breach Bitcoin’s elliptic curve signatures. According to Edwards, this is possible within the next two to three years. Mow’s comments emphasize that although there are currently no quantum computers capable of decrypting ECDSA, Bitcoin is evolving solutions to protect its long-term cryptographic security.
Q&A
What are the quantum threats to Bitcoin according to experts?
Experts warn that quantum computers could potentially break Bitcoin's ECDSA signatures using algorithms like Shor's, but current quantum computers are not yet capable of this.
How is Bitcoin preparing for potential quantum computer threats?
Bitcoin is developing quantum-resistant solutions, such as the Quantum Safe Bitcoin proposal and zk-STARK proofs for wallet recovery, to enhance its cryptographic security.
What did Charles Edwards say about quantum computers and Bitcoin?
Charles Edwards indicated that quantum computers might only need around 700 usable qubits to breach Bitcoin's security, a possibility he believes could arise within the next two to three years.
