> Why is clock skew being used here at all? You're right, it's not actually necessary to use the client clock at all. It was easier to implement it that way initially and I kept it in the description and didn't think about it again.. Thanks for pointing that out. Since all timestamps are measured, the calculations can actually also be made afterwards without using the client clock timestamps at all. However this may add a bit more noise. > not the actual nonce The nonce can only be used once so it's ok to share it afterwards.
