VaultFS: Data Integrity via Write-Once Software Support at the File System Level

VaultFS is a file system (the software layer that manages how files are stored and organized on a computer) that ensures data integrity (accuracy and trustworthiness of stored information) by implementing write-once storage at the file system level, meaning files can only be written once and cannot be modified afterward. This approach protects against accidental or malicious changes to critical data by making it impossible to overwrite or alter files after they are created.
