Thanks for providing this information, I was not aware of that many layers although I did hear about liquid a few weeks ago. I learned how beneficial it is for big investors and whales as it has lesser traffic and a faster tx feature. Overall I knew about BOB as I joined there points system by holding ETH. Later they became expensive so I left. Never heard about Rootstock (3rd place) will learn about it as well.
Plus I also was not aware of these chains i.e. side chain, drive chain, etc. Never heard about them before I think I did not learned anything all these years or its just these chains are new in the market. Babylon is not present in the first link why is that?
