Great thanks for this. You're right, DLC's are complex and specification is a work in progress. I tried last year by running Bitcoin-S on my node and using Suredbits oracle explorer but could never get to the CET execution. Maybe I was just too stupid, or there's been a since updated spec, but I'm going to try again with the PLTC method you described, cuz we need a tutorial up for the inbound StackerSports gambling escapades.
