mpunks Miner Controller

The mining controller is a simple HTTP server that returns the data needed to mine mpunks (through /mining-inputs), and allows the miner to submit valid nonces for minting via /submit-work?nonce="0xhexstring".

This server will act as the blockchain-interfacing component of the official mpunks GPU miner, and could act as the blockchain-interfacing component for any mpunks mining software.

Spec

ANY ENDPOINT RETURNS:
{
    "status": "success" || "error",
    "payload": { ... }
}

GET /mining-inputs
success payload:
    {
        "lastMinedAssets": "0xhexstring",
        "senderAddressBits": "0xhexstring",
        "difficultyTarget": "0xhexstring"
    }

GET /check-nonce?nonce="0xhexstring"
success payload:
    {
        "nonceStatus": "..."
    }

POST /submit-work?nonce="0xhexstring"
success payload:
    {
        "nonceStatus": "...",
        "gasStatus": "...",
        "txHash": "0x....."
    }

POST /heartbeat?hashrate=1234567
success payload:
    {}

Usage

Setup

Install and use Node 14

nvm install 14
nvm use 14

Create .env.local from .env

cp .env .env.local

Read LICENSE and NOTICE, then fill in environment variables within .env.local.

Run

Only tested with Node 14.

Quickstart

nvm install 14
nvm use 14
yarn install
yarn start

Run to watch a pooled miner result

Just set POLL_POOLED_MINER_RESULTS with the value true and POOLED_MINER_RESULT_URL with an URL which returns a valid JSON structure:

{
  "address": "0x0000",
  "error": null,
  "success": true,
  "nonce": "0x0000",
  "ts": "Thu Oct 14 2021 11:58:36 PM"
}

If this URL returns a valid nonce with the same address than the one you provided a private key for, and if the gas is low enough, a mint transaction will be executed to mint an mpunk with the found nonce.
