Blockchain and radio communications over suborbital spaceflights: Watchtowers and Mystics
This addresses communication challenges in suborbital spaceflights, but it appears incremental as it applies existing blockchain concepts to a new domain without clear evidence of novel breakthroughs.
The paper tackles the problem of secure and reliable communication between ground and satellites over long distances by using blockchain technology and a network of ground nodes, resulting in a system where satellites discover nearby stations and distribute verified information through master (Watchtowers) and working (Mystics) nodes.
The communication between ground and satellites is tough due to long distances and interferences in the propagation medium. Using the blockchain technology and a series of ground nodes, information can be distributed in a secure and reliable way. The satellite discovers nearby ground stations and sends the information that it is verified with other nodes present in the same network. Ground nodes are classified into two types, master (Watchtowers) and working (Mystics) nodes. The Watchtower controls the entering gate of new nodes to the network and the distribution of information between the working nodes.
