Summary:In this letter, a layered multi-chain spectrum blockchain architecture is proposed for Space-Air-Ground Integrated Network (SAGIN) to significantly reduce system overhead and aggregated interference. Considering the dynamic characteristics of SAGIN, nodes can make hand off between different blockchains based on the interference conflict graph to maintain aggregated interference below the threshold. To further improve spectrum utilization while avoiding harmful interference caused by spectrum trading in SAGIN, a spectrum trading mechanism is proposed, which jointly considers spectrum pricing, deployment location, and transmit power optimization. Simulation results verify the effectiveness of the proposed spectrum blockchain architecture and trading mechanism.
