The github explains that you create a transaction as follows:<p>1) You have 50 coins in a &#x27;bucket&#x27; or address?
2) You send 18 to a friend
3) You send 32 t yourself.<p>So you create two encrypted buckets, 18 in one, and 32 in the other.  They seem to be the equivalent of UTXOs. I&#x27;m not clear if they need to be &#x27;revealed&#x27; to be spent though.
