As quantum computing advances, the security of blockchains like Bitcoin and Ethereum is at risk. This video from the Crypto Chronicles podcast dives into how quantum computers, powered by Shor's and Grover's algorithms, could break current cryptographic security. We explore the threat in detail, from the risk to public-private key pairs to the "Harvest Now, Decrypt Later" strategy.

Learn about the cutting-edge solutions being developed, including:

Post-Quantum Cryptography (PQC): Upgrading current systems with new, quantum-resistant algorithms based on lattice cryptography, as standardized by NIST.

Quantum Blockchains: The futuristic concept of building blockchains on quantum principles, and how technologies like Quantum Key Distribution (QKD) could secure communication.

The transition to a quantum-resistant future is inevitable. We discuss the critical path forward, emphasizing the need for crypto-agility and widespread upgrades before it's too late.
