The episode describes Q-PnV, a new quantum consensus mechanism for consortium blockchains, designed to withstand the threats posed by quantum computing. It builds on pre-existing protocols (PoV and PnV), integrating quantum voting, a Quantum Random Number Generator (QRNG), and Quantum Key Distribution (QKD). This approach, leveraging the entangled state of quantum particles, aims to ensure enhanced security, anonymity, and transaction verifiability. Although its implementation requires advanced quantum infrastructure, Q-PnV represents a long-term investment strategy for securing consortium blockchains in the quantum computing era.
