Technical Field

Background
The blockchain technology is a brand new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secures data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data. The blockchain technique itself has many advantages: on one hand, as the blockchain network can realize self-restraint through an algorithm, the behavior of any malicious fraud system can be rejected and restrained by other nodes in the network, and therefore, the blockchain system can realize safe network transaction without depending on central authority support and credit endorsement. On the other hand, as the block chain adopts the one-way hash algorithm, and each newly generated block is strictly advanced according to the time linear sequence, the irreversibility of time causes that any behavior trying to invade and tamper the data information in the block chain is easy to trace back, and causes the rejection by other nodes, thereby limiting the related illegal behavior. Therefore, the blockchain technology is increasingly widely applied to various fields such as finance, banking and the like.
