Hive Application Framework
Basically an interface for developers to connect their apps with the Hive blockchain without having to get so deep into blockchain stuff. It's being developed by blocktrades (the blocktrades team does a lot of Hive core development)

It will be a plugin on a witness server parsing data in real time rather than a separate process of streaming through blocks like Hive Engine or other layer 2 services use now. The idea is it will be fast and easy to build Hive dapps

So this will be similar to the application layer on the evm and allow for the deployment of for lack of better words smart contracts?
You got any suggested reading about the HAF?

An application layer, exactly. The specifics aren't well known yet

Hints about HAF come in blocktrade's posts, and he sometimes asks for public input and we get to see some cool documents to deep dive into. All of his recent updates will mention something about HAF, usually near the end. Hopefully, we'll see it in the wild in the coming weeks. I'd be surprised if it takes more than a couple of months from now for us to see it in action

Thanks. I'll go through his posts.
