Integrating btcd into warnet

[lucasdbr05]

I am working on a research project with an implementation of fountain codes in bitcoin nodes (especially btcd), and the warnet environment is well-suited for running some tests. For this reason, I started an integration of btcd into warnet with the goal of running some tests in the future.

I would like to know if it is of interest to the maintainers for warnet to support the integration of other bitcoin nodes (like btcd). In a conversation with @edilmedeiros, we discussed that adding other nodes such as Floresta and Utreexod could be interesting in the future.
When doing so, a framework for writing scenarios related to this type of node would be necessary. I believe that, at least for btcd, an approach similar to the one used in scenarios/ln_framework , creating an API that communicates with btcd's JSON RPC API, would be the best path forward.

… and libbitcoin.

There's quite some buzz in parts of the community about having alternative bitcoin node implementations and warnet could become more important to support testing and research of interoperability.

I agree it would be useful to test integrations across implementations. I took a look at your branch and I'm not sure if its the right approach yet. It's the differences in config file format and RPC interface I think will give you big headaches just trying to swap in btcd for bitcoin core in an abstract warnet tank.

You can see for example how we support lnd and cln with a series of abstract classes that normalize the API commands and even channel policy field names.

Has this branch been working for you pretty well already?

Do you guys wanna chat more informally? We can meet on the bitcoin dev project discord server, #warnet channel: https://discord.gg/y7QCPdh2

This branch is working. It’s possible to spin up a network with btcd nodes and interact via the command line using warnet bitcoin rpc. I’m currently developing a layer/abstraction to simplify communication with the btcd JSON-RPC API, following the same pattern already used for lnd and cln.

warnet bitcoin rpc

Okay but not in scenarios? (would require abstraction of BitcoinTestFramework's RPC system)

What have you been doing with it?
