In recent years, the attitude of bitcoin in the world has fallen, but a blockchain technique, which is one of bitcoin underlying techniques, has been increasingly emphasized. In the process of forming the bitcoin, the blocks are storage units one by one, and all communication information of each block node within a certain time is recorded. The blocks are linked through random hashing (also called hashing algorithm), the next block contains the hash value of the previous block, one block is connected with one block successively along with the expansion of information exchange, and the formed result is called a block chain.
What is the blockchain? From a technological level, the blockchain involves many scientific and technical problems such as mathematics, cryptography, internet and computer programming. From the application perspective, the blockchain is simply a distributed shared account book and database, and has the characteristics of decentralization, no tampering, trace remaining in the whole process, traceability, collective maintenance, public transparency and the like. The characteristics ensure the honesty and the transparency of the block chain and lay a foundation for creating trust for the block chain. And the rich application scenes of the block chains basically solve the problem of information asymmetry based on the block chains, and realize the cooperative trust and consistent action among a plurality of main bodies.
Electronic maps (english: Electronic maps), i.e., digital maps, are maps that are stored and referred to digitally using computer technology. The method for storing information in electronic map generally uses vector image storage, the map scale can be enlarged, reduced or rotated without affecting the display effect, the map scale can not be enlarged or reduced by using bitmap storage in early stage, and modern electronic map software generally uses geographic information system to store and transmit map data, and also has other information systems.
At present, the related technology of a block chain is not introduced in the design and use of an electronic map, and a reliable management mechanism of the block chain on data cannot be fully utilized, for example, running reference information of whether a vehicle deviates from a current running road cannot be quickly and accurately given to a snow running environment.
