The block chain is a distributed account book system, is commonly maintained by a plurality of nodes, and is characterized by being not easy to tamper, difficult to forge and traceable. The blockchain records all information of the transaction, and once data enters the blockchain, even an internal worker cannot make any change in the blockchain. This unalterable feature comes not from using some kind of operation, but from the block chain system and mechanism itself. This makes the use of block-chaining techniques simpler and more efficient than other security techniques. The blockchain technique can be used in places where fairness, fairness and honesty are needed.
Intelligent contracts are divided into two categories, one with legal power, i.e., actual intelligent contracts, one called on-chain code, which is code that runs on top of a blockchain, with no legal power. Generally, the intelligent contract system exists by relying on a block chain system and is built in the block chain system. After the intelligent contract transaction enters the block chain system, the intelligent contract transaction is executed through the intelligent contract module, the executed data is jointly identified and linked through the block chain, the whole process is completed inside the block chain system, the intelligent contract data comes from the block chain account book where the intelligent contract data is located, and the execution result is stored in the same account book.
