Spent some time delving into the version management mechanism of a certain storage project, especially its handling of uploaded files and incremental changes. Discovered that it can track the complete historical state of files and revert to any version at any time — far beyond traditional undo or restore functions. Even more powerful is the fine-grained access control mechanism, which allows you to precisely define different users' permissions for various historical versions. This opens up a lot of possibilities for enterprise applications and data governance. This is how true decentralized storage should be played.
