Interledger Stack

[KarmaCoverage]

I have been reading about SPSP today and wanted to create a thread for discussion on the various aspects of the ILP stack, (like used to be on this forum when RCL was being developed). 

If I am understanding correctly, by using PSK  "Pre Shared Key", the two end points of a TX are able to share a fulfillment/receipt. I think this works by the sender requesting from the receiver the PSK, that way when the receiver gets the value transferred, the receiver can return a signed receipt to the sender, informing the sender that the TX was completed properly.

Would it be correct/wrong to assume this same schema is used between direct peers in each hop within a multi hop ILP TX?

Just trying to play some catch up, as I have not been able to stay on top of ILP's development and thinking.

@KarmaCoverage is this graphic from ILP website somewhere?  (I don't remember running across that one)

I think it was on twitter.

but there has been some educational email threads on the ILP W3 email recently. Adrian and a few others discussing ILP development.
