So is this essentially, in comparison too to ethereum, we can designate our own node and build whatever I want on top of it? say a petshop? what about ICO's is there capability to write ICO's to interact with the main STEAM network via the node? or vice versa?

are there any frameworks developed like solidity but for STEEM

I am trying to get a handle on the capabilities, tools, and resources. I would like to help getting to develop new tech and possibly help with new deployment frameworks on top of this network I have a good feeling this platform is going to blow up in a short amount of time.
