For instance this is interesting: https://gist.github.com/moonsettler/e0c24863fda418a2fb504a307fda8a19 but I don't entirely understand how the escrow works, and it's kind of assumed the reader already knows. Maybe I haven't been following CTV as close as I ought to have been, but I don't know how that's supposed to be set up. I also don't understand the (potential?) incentives issues this might cause.
