A blockchain smart contract construction method

Abstract

The invention discloses a block chain intelligent contract construction method, comprising the following steps: (1) the intelligent contract is decomposed into a plurality of action operations, and the action operations of the intelligent contract are not related to each other; (2) Write each action operation using SQL-like syntax; (3) Antlr technology is used to generate standard AST tree for theaction operation. The AST tree is translated into the function code of the corresponding block chain language, and the four arithmetic operations and function calls are carried out. (4) Build the framework of intelligent contract development, and introduce the translated function code file into the framework of intelligent contract development; (5) According to the translated function code, the corresponding intelligent contract is generated by on-line compiling module of intelligent contract development framework, and the construction of block chain intelligent contract is completed. The invention reduces the development difficulty of the block chain intelligent contract, and the area chain of different languages can be uniformly developed, thereby providing convenience for the intelligent contract developer.

Description

technical field [0001] The present invention relates to the field of blockchain smart contracts, in particular to a method for constructing blockchain smart contracts. Background technique [0002] A smart contract is based on and runs on a blockchain, and a smart contract is a computer protocol designed to disseminate, verify or execute contracts in an informational manner. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible. The purpose of its smart contracts is to provide a method of security superior to traditional contracts and reduce other transaction costs associated with contracts. [0003] Due to the advantages of higher efficiency in processing transactions, irreversible, secure transactions and fully automated processes, smart contracts have received extensive attention and rapid development in recent years. With the development of blockchain and smart contracts, the current blockchain smart contract develop...

Problems solved by technology

With the development of blockchain and smart contracts, the current blockchain smart contract development methods are different on different blockchains (Ethereum and EOS), resulting in the inability of the two contracts to be universal. When multi-language types are supported on the block chain, the programming language is difficult to understand and requires strong logical thinking ability, which increases the difficulty of smart contract development. How to reduce the difficulty of smart contract development is an urgent problem for relevant personnel
