Thanks for putting the effort, sounds really cool! Unfortunately I wasn’t here from the beginning. However i’ll post some links and findings that i found and hopefully others can share their parts as well.
I really liked this interview:
The History & Future Of Ethereum Classic - By Charles Hoskinson https://www.youtube.com/watch?v=SQZB3pAhjP4 (whole talk is here: https://www.youtube.com/watch?v=dMNhOIUcOYo)
We also had our first summit: https://etcsummit.com/resources/
Here is a character that I found interesting from the history on reddit:
A user ‘whatisgravity’ joined reddit on july 17th 2016 and made a post saying he is patching ethereum client that will default to original chain
A day after he opens an issue on github and on july 24th he asks the community to help
From the github issue we can see some familiar faces like splix, Charles Hoskinson, Cody Burns, arvicco,…
He stopped posting on reddit for some time (disappeared) and then posted again saying he was working on an ETC project:
I know that i gave some really specific things and probably left out a bunch of important things so I encourage others to fill in. I think we should gather as much data as possible about the history while we have members who were there from the start.
P.S. I’m not saying you should put these things in the video, just sharing my findings
