Problems solved by technology

[0003] However, the existing system only supports basic operations such as creation, authorization, addition, deletion, modification, and query of database tables on the chain. If users want to use this system to complete complex business logic, they need to develop an additional set of centralized system to call the basic operations of these tables
There are two problems in the above-mentioned blockchain system that supports database operations: one is that the business logic of database operations is opaque and is outside the blockchain; the other is that the call to the database is not flexible enough

Abstract

The invention discloses an intelligent contract deployment and calling method and device. The intelligent contract deployment method is executed by block chain nodes and comprises the steps of receiving a first transaction containing byte codes of an intelligent contract, wherein the intelligent contract is compiled and compiled in advance according to business logic, and the business logic comprises at least one basic operation on a table of a database; Sending the first transaction to a block chain network consensus to obtain a calling address corresponding to the smart contract; And sendingthe calling address to a client which submits the first transaction. According to the technical scheme provided by the embodiment of the invention, the intelligent contract is deployed to the blockchain network, so that the service logic is linked through the intelligent contract, and the problem that the service logic is opaque is well solved.

Description

technical field [0001] This application generally relates to the technical field of data storage, and in particular relates to smart contract deployment and calling methods and devices. Background technique [0002] In the existing technology, the system that combines the blockchain and the database, the user can send the corresponding transaction to the blockchain like an ordinary database, the transaction will be recorded in the blockchain network, and will be reflected in the underlying database come out. The system realizes the separation of database operation records and implementation, which greatly improves the security and flexibility of traditional databases. [0003] However, the existing system only supports basic operations such as creation, authorization, addition, deletion, modification, and query of database tables on the chain. If users want to use this system to complete complex business logic, they need to develop an additional set of centralized The syst...
