Quantum Threats to Cryptography: What You Need to Know 🔐 (Episode 5 of 8)

In this urgent, accessible, and deeply researched episode, hosts Jess and Alex tackle the most pressing question for digital assets and global finance in 2025: Is quantum computing about to breach blockchain security? Drawing on breakthroughs like the 2025 Nobel Prize in Physics, they explain—in everyday language—how quantum computers could eventually break the cryptographic foundations of Bitcoin, Ethereum, and beyond. The episode features:

• Breakdown of Quantum Computing: The real science behind superposition, entanglement, and modern qubit hardware.
• Cryptographic Risks: Clear explanation of how Shor’s and Grover’s algorithms target RSA, ECC, digital signatures, and blockchain consensus models.
• Harvest Now, Decrypt Later Threat: Why your encrypted blockchain data today might not be safe tomorrow.
• Real-World Responses: From El Salvador’s wallet splits to the SEC’s Post-Quantum Financial Infrastructure Framework, plus industry migration paths and hybrid cryptography.
• Post-Quantum Algorithms and Standards: Deep dive into NIST’s new PQC standards, including Kyber, Dilithium, FALCON, and SPHINCS+.
• Experimental Quantum Secure Networks: How quantum digital signatures and chip-scale integration are moving from lab to real world.
• Investor and Developer Actionable: How listeners can protect digital assets, advocate for crypto agility, and plan for a hybrid quantum future.

Call To Action:

• Protect your digital assets: update wallets, avoid key reuse, and demand post-quantum readiness from your providers.
• Support open-source post-quantum migration efforts.
• Share this episode with crypto developers, investors, and security professionals.
