The Wolf Of All Streets Insider Reveals Bitcoin’s Biggest Threat... And No One Is Ready!
Apr 1, 2026
Alex Pruden, CEO of Project 11 and advocate for post-quantum blockchain readiness. He explains how quantum computing and new research could weaken Bitcoin’s signatures and expose old wallets. They discuss recent papers that lower attack costs, Taproot’s implications for key exposure, and urgent steps needed to plan a post-quantum migration.

Episode notes
Quantum Breaks Bitcoin Signatures
- Quantum computers can reverse public keys to private keys, breaking Bitcoin signatures secured by the discrete log problem.
- Alex Pruden explains that knowing an address's public key would allow a quantum attacker to derive the private key and spend funds.
Mining Remains Hard To Quantum Attack
- Grover's algorithm offers only a modest speedup against hash functions, so quantum attacks on Bitcoin consensus are largely impractical.
- Alex contrasts Grover's tiny advantage with Shor's exponential power against signatures.
Algorithmic Advances Shrink The Barrier
- Recent papers lower resource estimates to attack Bitcoin signatures by optimizing algorithms for Bitcoin's specific cryptography.
- Pruden notes the Google and Caltech analyses move the "field goal" much closer even if machines don't yet exist.
