CDEdit: Redactable Blockchain with Cross-audit and Diversity Editing

（This paper accepted by 2022 IEEE International Conference on Trust, Security and Privacy in Computing and Communications (TrustCom), please click on the final submission version)

We use python and the charm framework to implement a highly applicable redactable blockchain (CDEdit), which has controlled editing privileges and supports multi-edit types.

Note

Since the previous experiment was done in a virtual machine (Ubuntu system), but now it can no longer be opened, tried various methods or not. The only thing I can do now is to back up the source code from the middle of the experiment.

Note: Before the paper name is still called "FitsMe", but later changed to "CDEdit", the code content can be understood by synonymous replacement, does not affect the compilation.
