What do you mean by “built on top of”? I understand the concept of gas price and gas limit.
I guess my question really is... are these tokens operating on the same network?
Are token transactions uploaded into the same transaction pools and included in the same blockchain?
Mined/ authenticated by the same nodes?
At the same time as the native coin?
How do I find out if a unit is a protocol or token of what protocol?

I know it’s allot of questions. Thanks for helping understand tokens vs clones.
