Thanks for the wonderful talk! I really like the comparison between Git and Blockchain. The data structure of these two are quite similar but the way they solve conflicts is very different. I think a graph of comparison between these two would be extremely helpful!

In ethereum, there is something called uncle blocks. Which is sorta like an merging mode. Look it up!
