Background
The blockchain is a novel decentralized information technology, can safely store digital transactions or other data, cannot be forged and falsified, and is a bottom layer technology of digital currencies such as bitcoin, Ethernet currency and the like. And the transaction confirmation on the blockchain is completed by the consensus of all the nodes on the blockchain, and the block is packed and written after the consensus is successful. The block chain maintains a public account book for storing all transactions on the block chain network, and any node of the public account book on the storage block is a complete copy, so that the common account book can not be forged and falsified, information sharing is realized, and the efficiency of transaction and information circulation can be improved.
The federation chain, an implementation form of the blockchain, is only directed to members of a certain group and limited third parties, and the generation of each block is jointly determined by all preselected nodes. Members of a federation chain refer to enterprises, financial institutions, and other institutions that join the federation through federation authentication.
The intelligent contract on the block chain refers to a string of binary codes which are written and compiled by languages such as Solidity, LLL and the like and run on the block chain, data storage, reading and writing and some logic operations on the block chain can be realized through the intelligent contract, most block chain applications run on the basis of the intelligent contract at present, the Solidity language used by the intelligent contract is complete in picture, and all operations of application service logic can be realized.
In the existing alliance chain, a judgment standard for judging whether the intelligent contract can be linked does not exist, and therefore, it is particularly important to design a technical scheme for judging whether the intelligent contract can be linked.
