1. A satellite-based blockchain architecture, comprising a terrestrial blockchain miner network, a constellation system, and a consensus protocol coordinating the constellation system and the terrestrial blockchain miner network, wherein
the terrestrial blockchain miner network comprises more than one terrestrial miner, and the terrestrial miners are communicatively connected via a network;
the constellation system is formed by three or more satellites, the satellites are communicatively connected to each other via a network, and the satellites and the terrestrial miners are communicatively connected to each other via a network; and
the consensus protocol coordinating the constellation system and the terrestrial blockchain miner network is used for generating an oracle by a satellite in the constellation system and controlling the constellation system to broadcast the oracle to the terrestrial blockchain miner network; a corresponding terrestrial miner in the terrestrial blockchain miner network has the right to generate a new block, and broadcasts the new block to other terrestrial miners by using the terrestrial blockchain miner network;
and other terrestrial miners receiving the new block checks the validity of the block, and if the check succeeds, the block is broadcast to other terrestrial miners by using the terrestrial blockchain miner network.
