HTTP support for the local-tx-submission protocol

[KtorZ]

Describe your idea, in simple words.

Enable routing HTTP requests to the local-tx-submission protocol. A typical request would be:

• verb: POST
• content-type: application/cbor or text/plain
• accept-encoding: application/json
• body: raw binary (when application/cbor) or an encoded base16 string when text/plain

The response would be the full local-tx-submission response, including detailed errors on failure.

Why is it a good idea?

The local-tx-submission is a simple-enough protocol with no state; it is therefore a likely candidate for HTTP rest-like interfaces. It also reduces the entry barrier even more, as connecting and sending through a websocket is less idiomatic than firing an HTTP request for most ecosystem.

Are you willing to work on it yourself?

Yes.
