Current blockchain technology is considered the next generation of subversive core technology following steam engines, power, the internet. If say that steam engine released people's productivity, electric power solved people's basic life demand, the internet thoroughly changed the mode of information transfer, then the blockchain as constructing the trusted machine will probably thoroughly change the mode of whole human social value transfer.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system.
In a plurality of block chain networks which operate at present, each transaction is broadcasted to the whole network, and each whole node in the network carries out verification calculation on the transaction, so that although the safety of an account book is ensured, transaction congestion is caused, and the throughput is not high. With the increase of the application of the blockchain, the expansion of the blockchain is urgent, and the fragmentation is a widely accepted expansion scheme. The segments can be segmented according to the network, the transaction address or the state, and most of the schemes adopt random division, for example, a user living in the united states may be segmented into one segment with a user living in china, which reduces the network traffic, but does not consider the actual geographic location factor of the user, the communication efficiency inside the segment is low, and the actual volume expansion effect may not be large finally.
