  Hi Simplenote team,

  I’m currently writing my Bachelor’s thesis in Software Engineering, and I’m doing a comparative study of note-taking applications focusing specifically on their versioning mechanisms. I’ve chosen Simplenote as one of the applications to analyze.

  I was hoping you could shed some light on how note versioning is implemented under the hood in Simplenote. Specifically, I’m trying to understand:

  • What storage strategy is used for versioning? (e.g., full snapshots at each save, delta-based storage where only the differences between versions are stored, or a Content-Addressable Storage approach)
  • Is there a hashing algorithm involved in identifying or deduplicating versions?
  • Are there any public technical resources, blog posts, or documentation that describe the internal architecture of the versioning system?

  I understand this may touch on implementation details that aren’t publicly documented, but even a high-level description would be incredibly helpful for my thesis. Proper academic attribution will of course be given to any information provided.

  Thank you in advance for your time!
