As a matter of transparency and of user and community education, I think it is important to properly catalog and make public the side-tangle-to-tangle stitching process that has been conducted by either the IOTA Foundation (IF) or a private party.
As the IF has publicly stated, there are not many concerns with the side-tangle as stated in a Medium blog entry by Lewis Freiberg of the IOTA foundation, “What’s up with the Tangle?”, then there should be no need for secrecy or confidentiality with this information—especially for a network that is aiming for eventual full-decentralization.
What is the stitching process?
Who is doing the stitching?
If this is not the IF, then who, and are they doing this in cooperation with the IF?
How are the nodes for stitching selected?
What is the exact process undertaken?
For all developers in the community, the sharing of the process would be immensely useful and helpful.
