How to setup :

1. Create a valid8 folder in your path: mkdir ~/.local/share/valid8

2. Dump the metaplex program there: solana program dump -u m metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s ~/.local/share/valid8/metadata.so

3. Create bash script with sudo nano /usr/local/bin/metaplex-test-validator then paste in the following code and save: (if the /user/local/bin directory doesn't exist, you can create it using sudo mkdir -p -m 775 /usr/local/bin)

#!/bin/bash

A far from exhaustive list of reasons why mAPI is shit

1. While it's an acceptable bandaid for now, we probably shouldn't just wrap JSON-RPC. It's really slow, and there's no reason to run an HTTP server that accesses another HTTP server. It's pretty silly tbh.
2. Nobody likes C#. Like, nobody.
3. You shouldn't have to go and install an entire postgres database in parallel to a mining node (both of which just love to compete with eachother to consume maximum resources) just to offer people different fee rates. If you had to do something like this, SQLite would be a much more lightweight alternative, however in almost all cases, miners will probably want to just run their own mining consoles (like any other kind of API service provider would) where they manage all this stuff themselves, so in reality, a simple JWT with an exp field, a fee field and a signing secret without any kind of user management whatsoever is probably already sufficient. If you have strong opinions to the contrary about thi
