Oct 4, 2025
What happens when quantum computing meets Bitcoin? Delving into the potential risks, the host discusses how Bitcoin’s encryption might hold its ground against quantum threats. We learn about the vulnerabilities of early Bitcoin schemes and strategies to secure at-risk coins. The conversation covers best practices for wallet security, including using new addresses and self-custody. With insights on ongoing innovations in blockchain technology, he emphasizes calm and common-sense precautions for Bitcoin users in the face of evolving threats.

Episode notes
Quantum Risk Is Real But Not Immediate
- Quantum computing is possible but not yet probable, so immediate panic is unnecessary.
- Google warned about 'Bitcoin-like encryption' but we lack the machines to execute that threat today.
Public Key Visibility Determines Vulnerability
- Bitcoin uses public and private keys and later schemes hide the public key with a hash.
- Hiding the public key with a hash makes most Bitcoin resistant to quantum attacks until the key is revealed.
Move Pre-2010 Coins To New Addresses
- If you mined or hold coins from 2009–March 2010, move them to new addresses immediately.
- Moving those old P2PK coins replaces exposed public keys and restores security against quantum attacks.
