I can not discover any info on what info is definitely contained inside a lightning transaction.

Let’s imagine Alice desires to pay Bob on lightning and routes by way of R1, R2, R3 within the following order

Alice > R1 > R2 > R3 > Bob

I assume Bob must know info relating to the channel UTXO from Alice, in any other case how would Bob know that the channel is funded?
If this assumption is true, how is Lightning extra personal than Bitcoin? (aside from the truth that nodes needn’t retailer the knowledge on channel UTXO’s [but they can if they want…])

If Bob is thought amongst authorities as a typical endpoint for whoever they’re focusing on, they will compel Bob to disclose if he obtained a fee which was funded from a channel with some identified UTXO (they might know the channel UTXO from on-chain evaluation of their monitoring of Alice). If Bob is logging the knowledge he is paid with, then he would have the flexibility to adjust to this authority, successfully making this Lightning fee no extra personal than a Bitcoin fee. If Alice gave Bob some private info in relation to the fee, this is able to utterly dox Alice to authorities.

Additionally, does R1, R2, R3 additionally know the channel UTXO?

If the channel UTXO is just not identified amongst members, how does the goal channel validate that the supply channel is funded?

Would admire steering on this

Thanks
