Brian Quarmby reports in cointelegraph.com that "United States banking giant JPMorgan Chase has unveiled research on a quantum key distribution (QKD) blockchain network that is resistant to quantum computing attacks.
QKD utilizes quantum mechanics and cryptography to enable two parties to exchange secure data and detect and defend against third parties attempting to eavesdrop on the exchange. The technology is seen as a viable defense against potential blockchain hacks that could be conducted by quantum computers in the future.
The proof of concept network infrastructure relied on Toshiba’s Multiplexed QKD System, manufactured by Toshiba Europe at their Cambridge UK base, and Ciena’s Waveserver 5 platform, equipped with 800 Gbps optical-layer encryption and open APIs running over Ciena’s 6500 photonic solution.”
