A Survey on the Integration of Blockchain Smart Contracts and Natural Language Processing

Smart contract is an automated contract system based on blockchain technology, which is self-executing, tamper-evident and decentralized. The writing and analysis of smart contracts still face several challenges, including complex programming languages and potential security vulnerabilities. Natural Language Processing (NLP) as a discipline that studies the interaction between natural language and computers, can provide strong support for the development and analysis of smart contracts. This paper explores the cross-application of blockchain, smart contracts and NLP. First, this paper introduces the basic principles of blockchain technology and the concept of smart contracts. Then it points out the problems in the development process of smart contracts, and focuses on the analysis and summary of the relevant research results of NLP technology in the generation of smart contract code and annotation generation, and summarizes and analyzes the important role of NLP technology on the efficiency of smart contract development, the correctness, reliability, readability, and maintainability of the code. Secondly, for the security of smart contracts, the research related to smart contract vulnerability detection using NLP technology is summarized. Finally, the advantages, challenges and future development directions of combining natural language processing with blockchain smart contracts are pointed out to provide reference and inspiration for research and application in related fields.
