```Hey this is Zee, I am founder of Space Chain. We have already finish building our first satellite with Qtum and it is welded on rocket and ready for launch soon. We believe satellite nodes add a new dimension of diversity of nodes and make the system more decentralized. Current blockchain technology applications use computer as nodes and adopt ground-network-based transmission channel. The singular network and singular node pose great security risks. Once node computer or transmission network is under attack, the entire blockchain network may be greatly impacted . Therefore, from a security perspective, blockchain needs to have diversified transmission networks and nodes with multiple data storages to enhance system safety and security. It will be connected with ground station to receive/use data, and there are also IOT testing devices. On the first satellite, we creatively use Raspberry Pi to run the Qtum test node. It will the first time that Raspberry got brought to space. In future, what hardware we have on the satellite will be dependent on what kind of services it provides. As I said, the first satellite is finished and welded on the rocket. We expect the first satellite will be launched later this year. If everything goes well, we will have 4-8 satellites up there at the end of 2018.
