🗒⛏ notemine_hw ⚡⚙️

This is a fork of notemine.

notemine_hw is a rust-based tool for mining nostr notes under NIP13.

While its parent project compiles to WASM and caters for a web-native experience, notemine_hw aims to leverage hardware acceleration for mining notes.

UI/UX

The UI/UX aims for:

• Configurable PoW difficulty.
• Multithreaded workers.
• Realtime hashrate logging.
• User can mine and publish their own notes, or sell PoW for zaps.

So notemine_hw can be used in two different ways:

• CLI
• JSON-RPC

CLI

The CLI UI assumes that the user wants to mine and publish their own notes as JSON files from disk.

The notemine_hw mine subcommand is used for mining notes via CLI.

$ notemine_hw mine -h
Usage: notemine_hw mine --n-workers <N_WORKERS> --difficulty <DIFFICULTY> --event-json <EVENT_JSON> --relay-url <RELAY_URL> --log-interval <LOG_INTERVAL> --nsec <NSEC>

Options:
      --n-workers <N_WORKERS>        number of workers
  -d, --difficulty <DIFFICULTY>      difficulty (the number of leading zero bits in the NIP-01 id)
  -e, --event-json <EVENT_JSON>      path to event JSON file
  -r, --relay-url <RELAY_URL>        relay URL
  -l, --log-interval <LOG_INTERVAL>  log interval (secs)
      --nsec <NSEC>                  nsec
  -h, --help                         Print help

}

JSON-RPC

The JSON-RPC UI assumes the user wants to sell PoW for zaps.

PoW Price is calculated according to this formula:

$$ P = 2^{(d \cdot p)} $$

where:

• $P$: PoW Price [sats]
• $p$: PoW Price factor
• $d$: PoW difficulty

PoW sellers modulate their PoW Price factor $p$ in order to charge more or less sats according to PoW difficulty.

The notemine_hw sell subcommand is used to sell PoW.

$ notemine_hw sell -h
Usage: notemine_hw sell --n-workers <N_WORKERS> --log-interval <LOG_INTERVAL> --rpc-port <RPC_PORT> --pow-price-factor <POW_PRICE_FACTOR>

Options:
      --n-workers <N_WORKERS>                number of workers
  -l, --log-interval <LOG_INTERVAL>          log interval (secs)
  -r, --rpc-port <RPC_PORT>                  RPC port
  -p, --pow-price-factor <POW_PRICE_FACTOR>  PoW price factor
  -h, --help                                 Print help

A potential PoW buyer quotes the PoW price like this:

$ curl -X POST -H "Content-Type: application/json" -d '{
   "jsonrpc": "2.0",
   "method": "quote",
   "params": {
      "difficulty": 20,
   },
   "id": 1
}' http://localhost:1337
{
  "jsonrpc": "2.0",
  "result": {
    "difficulty": 20,
    "pow-price": 1048576.0,
    "pow-price-factor": 1.0
  },
  "id": 1
}

In the example above, the buyer needs to zap 100 sats to mine a note with difficulty 15.

The PoW buyer sends a zap (along with the event to be mined) via JSON-RPC. If the zap contains enough sats, the response contains the mined event id:

$ curl -X POST -H "Content-Type: application/json" -d '{
   "jsonrpc": "2.0",
   "method": "mine",
   "params": {
      "event": {
         "pubkey": "98590c0f4959a49f3524b7c009c190798935eeaa50b1232ba74195b419eaa2f2",
         "created_at": 1668680774,
         "kind": 1,
         "tags": [],
         "content": "hello world",
      },
      "difficulty": 15,
      "zap": "f481897ee877321783bb76133622b3cc344d691bb79cd6be88f44e819c3b2306"
   },
   "id": 1
}' http://localhost:1337
{
    "error": null,
    "id": 1,
    "result": [
        [
            "id": "0001db1f0f6951f2938ecbd0712bbed5dee721daf3b36f4d35309828a309eeee",
            "nonce": "18446744073709546934",
            "difficulty": "15"
        ]
    ]
}

If the zap does not carry sufficient sats, notemine_hw replies with an error, and the buyer lost their funds forever:

$ curl -X POST -H "Content-Type: application/json" -d '{
   "jsonrpc": "2.0",
   "method": "mine",
   "params": {
      "pubkey": "98590c0f4959a49f3524b7c009c190798935eeaa50b1232ba74195b419eaa2f2",
