14/// This type represents a JSON object loaded from daemon.json
15/// file. It does not describe its full structure, as it's not
16/// necessary for our purpose here. We only need to extract
17/// certain information from it.
18/// In practice, this format is never really used to convey
19/// the network's configuration, as the standard practice is to
20/// compile that into the OCaml node's binary.
21/// In theory, though, the underlying JSON file could contain
22/// more information that the following format describes. If
23/// that happens, the format can be extended to accommodate.
