A thorough understanding of blockchain bug characteristics is required to design effective tools for preventing, detecting and mitigating bugs. We perform an empirical study on bug characteristics in eight representative open source blockchain systems. First, we manually examine 1,108 bug reports to understand the nature of the reported bugs. Second, we leverage card sorting to label the bug reports, and obtain ten bug categories in blockchain systems. We further investigate the frequency distribution of bug categories across projects and programming languages. Finally, we study the relationship between bug categories and bug fixing time. The findings include: (1) semantic bugs are the dominant runtime bug category, (2) frequency distributions of bug types show similar trends across different projects and programming languages, (3) security bugs take the longest median time to be fixed, (4) 35.71% performance bugs are fixed in more than one year, performance bugs take the longest average time to be fixed. 2017-06-01T07:00:00Z text application/pdf https://ink.library.smu.edu.sg/sis_research/3695 info:doi/10.1109/MSR.2017.59 https://ink.library.smu.edu.sg/context/sis_research/article/4697/viewcontent/p413_wan__1_.pdf http://creativecommons.org/licenses/by-nc-nd/4.0/ Research Collection School Of Computing and Information Systems eng Institutional Knowledge at Singapore Management University blockchain Bug characteristics Empirical study Programming Languages and Compilers Software Engineering |

Bugs severely hurt blockchain system dependability. A thorough understanding of blockchain bug characteristics is required to design effective tools for preventing, detecting and mitigating bugs. We perform an empirical study on bug characteristics in eight representative open source blockchain systems. First, we manually examine 1,108 bug reports to understand the nature of the reported bugs. Second, we leverage card sorting to label the bug reports, and obtain ten bug categories in blockchain systems. We further investigate the frequency distribution of bug categories across projects and programming languages. Finally, we study the relationship between bug categories and bug fixing time. The findings include: (1) semantic bugs are the dominant runtime bug category, (2) frequency distributions of bug types show similar trends across different projects and programming languages, (3) security bugs take the longest median time to be fixed, (4) 35.71% performance bugs are fixed in more than one year, performance bugs take the longest average time to be fixed. |
