Ecash TIDES using Cashu and Stratum v2

In TIDES, shares are paid multiple times. I’m unsure if I follow how an eHash can be redeemed multiple times. Can you clarify that?

This would also enable shares to be exchanged by sending eHash tokens with an atomic swap spending condition (i.e., NUT-11).I think this is a huge benefit and something Ocean has said they would like to enable.

This is an exciting proposal. Thanks for putting it together!
