Close This week, SpaceX will launch an Ethereum (ETH) node to the International Space Station (ISS), marking the first time an ETH node has been launched into space. SpaceX has been hired by SpaceChain to deliver cargo to the International Space Station. The launch of the ETH node aboard the ISS will be the company's fourth blockchain payload to enter orbit, according to SpaceChain. It will serve as a "demonstration of the integration of Ethereum technology with its hardware on the ISS." The ETH node will be deployed on the International Space Station, and the security of the installations, according to SpaceChain, will be critical in keeping the ETH node network secure. The ISS installation solution for the ETH node will be provided by Nexus Inc, a SpaceChain client. The launch of the ETH node is set for June 3, 2021.
