I'm trying to grasp how this looks programmatically. When looking at the blockchain, I see operations and below this portion of a block, these operations appear be exclusive to the functionality of Steemit. For example: comments and votes.
Would one be able to utilize the Steem API to create any operation that suits the purpose of their application?
As subchains do have the complete Steem motor functions available this should be the case.
Allthough you could allready, Without the use of Subchains, create a clever App, with use of the API.
But as subchains would be, as far as I understood, Newly created objects, on their own subchains, this would give one really Different Apps. With API's to match.
