Yes, the current design is single-path. But I'm discussing the design as it will be when fully implemented.
Yes, single-path passes through only one xnode, if I'm not mistaken.
If a wallet sends fragments of a payment to multiple xnodes, which are all sending fragments to thousands of wallets, I do not think you will be able to find the receiver. But you are welcome to prove that you can.
Useless, thousands multiplied tx fee. Have to limit.
Tx is written to blockchain.
Have you heard dust threshold ?
You said thousands of wallets, payment to payee should be consolidated.
Payee will not tolerate with that.
My scenario above implies that a bad actor will have insufficient incentive. This is arguably ok.
I am also awaiting the white paper.
