/*

Despite the location of this file, the fixtures are in fact not created via `local_rpc` but a
modified dash unit test:

https://github.com/OttoAllmendinger/bitcoin/commit/0845a546e1bd97ac2037647f7398c6e20cfb7153

However the generated fixtures have the same format as the RPC responses so we will put the code here.
