I would like to understand how you will implement RingCT + PoS, because as far as I know the amount needs to be revealed to check that the 'weight' is indeed correct. I guess that you could include a range proof instead of revealing the exact amount, but it still is a big hint of the real UTXO amount. So how exactly do you plan to resolve this issue ?
Thanks for the question! As OrsonJ said, we'd been working on a technical paper and released it recently:
