基于区块链项目开发语言选型的初探

区块链技术及持续发展的各种开源区块链项目，正吸引着越来越多开发者的目光. 而繁多的主流编程语言及特色各异的区块链项目，使得开发者在开发基于区块链的系统与应用时，在技术选型上难免会有所困惑. 为此，对12个较知名的开源区块链项目，使用了源码统计工具Cloc统计其源代码，并进一步通过阅读相关代码及文档，分析和比较了其开发语言的构成. 同时，以图表的形式呈现其体量和关注度，从而为区块链开发者在选型上提供参考信息和建议.

Discussion of Selection for Languages Based on Blockchain Projects Development

More and more developers are being attracted by blockchain technologies and sustainable development of various open source blockchain projects. Nevertheless, the various popular programming languages and distinctive blockchain projects could perplex the developers inevitably when they commence to develop systems or applications based on blockchain. So, this paper utilizes a tool named Cloc to count the lines of source code in 12 well-known open source blockchain projects. By further reading codes and documents associated, we try to analyze and compare the programming language constitutions of the projects. Moreover, the paper demonstrates their project sizes and the attention degree to them in the form of charts. Finally, some reference information and suggestions about selections are given to the blockchain developers.
