One of the biggest banks in the United States, JPMorgan Chase, has released research on a quantum key distribution (QKD) blockchain network that can withstand attacks from quantum computers. This network is called QKD.
QKD uses quantum mechanics and cryptography to allow two parties to exchange secured data while detecting and defending against third parties trying to eavesdrop on the transaction. The method is thought to be a good way to keep quantum computers from hacking the blockchain in the future.
According to a February 17 statement, JPMorgan worked with Toshiba and Ciena to get the QKD blockchain up and running and to test it.
The study was done for people who live in cities. It found that the network could “continue to deliver 800 Gbps data speeds for mission-critical applications under real-world environmental conditions.”
Marco Pistoia, an engineer at JPMorgan Chase and the head of the FLARE Research group, said that before quantum computing can be used in the real world, a safe blockchain infrastructure must be built.
JPMorgan has been moving its blockchain projects along recently. Earlier this week, the bank became the first to officially start in the Metaverse. It now has a virtual lounge in the popular crypto-backed virtual world of Decentraland and looks optimistic about the Metaverse sector after labelling it a $1-trillion opportunity.
