• At kineto, this area was roughly implemented:

  • Erasing was done by overlaying with transparent ink instead of deleting elements.
  • Editing sticky notes’ text was like overriding the result of edits with slower timestamps.
  • It could be said that they were doing primitive CRDT.
  • However, doing CRDT in a place like kineto where there is an independent timeline seems interesting.
    • In typical CRDT use cases, it seems to be assumed that everyone shares the same time.
      • In that context, CRDT for handling delayed uploads, etc.
    • However, when doing CRDT in a collaborative editing editor where you can move along a timeline like time axis, edits made by moving on the timeline to the past are expected to be reflected later (blu3mo).
    • It seems interesting, and some convenient environment might emerge.
