Something like that, yes.
But it must look connective and not restrictive (cuz chains can also be associated with prison)
It should instead bring thoughts of communication and blockchain.
Is that hard to make?
I am not a designer, so I don't know.
Circles represent a community, in this case a community of resteem's surrounding Steemit. I am not sure I can represent a blockchain without using a chain.
I don't know how either.
Just think of anything that connects people and put a resteem logo on it.
