We could use ring signatures as access right authentication.
Each of your friends exchange pubkeys with you and each other, then you require an additional ring signature with each ecash transfer.
Meaning only your friends can transact the ecash among themselves, but nobody else can spend the ecash tokens.
Yet still there is perfect privacy among the tokens of your friends.
