① network routing ② cryptographic algorithm ③ script system ③ consensus mechanism
the security problem of blockchain is mainly the script system completed by script system, which is an abstract concept and an extremely important function in blockchain technology, The reason why a valuable network can be formed depends on the script system, which is driven like an engine and continuously sends and receives data. The so-called script refers to the program of some systems in the rule reconfirmation system, and the rules are fixed. For example, in the bitcoin system, only bitcoin can be sent and received, The system allows users to edit the program rules by themselves, and then they can deploy them to the blockchain ledger. In this way, the functions of the whole blockchain system can be expanded. For example, Ethereum realizes the function of smart contract through this set of custom script system, Then specific scenario applications or real life cases, such as order logistics information and supply chain information.
