Is anyone using it? I'm working on a human review / human in the loop platform that has some resemblance to it, while allowing for much greater customisation and flexibility.
Probably Ethereum or a stablecoin on top of the Ethereum blockchain. This would also open the door to supporting in-page transactions with Metamask, which might make a smoother experience.
We build highly customisable software for human in the loop operations. Our focus is on the software. We are completely agnostic to the human layer of the operation.
