I’d like to reference the Interledger Protocol in a paper, when referring to the current design generally (it doesn’t need to be any particular document). Since the original Interledger paper is so far out of date, I assume it would make more sense to cite the specification.
Here’s what I currently have, which is pretty basic:
@online{interledger,
author = "Interledger",
title = "Interledger Protocol v4",
url = "https://interledger.org/rfcs/0027-interledger-protocol-4/",
}
