Duinocoin mining in the browser (JavaScript: TV, smartphone, etc.)

When there is no other way: DUCO mining in the browser

No microcontroller, no PC, no Raspberry Pi, no installation: just with a JavaScript-enabled web browser you can already mine Duinocoin (DUCO).

If you don't have the possibility to install Python3 and don't own or want to buy a microcontroller, you can still mine Duinocoin (DUCO). All you need is JavaScript in a web browser.


To mine Duinocoin (DUCO) in a web browser (Internet Explorer, Firefox, Chrome/Chromium/Irirdium, Safari and so on) using JavaScript you need the following:

  1. a Duinocoin wallet (online account).
  2. an internet-enabled device with JavaScript in the browser.

1. create a Duinocoin wallet on the project page

In order to be able to store the mined Duinocoin (DUCO) somewhere, you need a wallet. This is managed online at Duinocoin. The new wallet is created at https://wallet.duinocoin.com/register.html.

Create a new wallet

Create a new wallet (a new account) at wallet.duinocoin.com.

2. internet capable device with JavaScript/browser

Every PC, every notebook, a Raspberry Pi, but also smartphones, game consoles and SmartTVs today have a web browser with JavaScript. It doesn't matter which operating system the device uses or which hardware is installed.

With the browser, you simply open the official Duinocoin Web Miner.


Fancy, but unfortunately extremely inefficient: the Duinocoin webminer written in JavaScript.

To mine Duinocoin you don't have to install or download anything. In the top section, in the simplest case, you only have to enter a single piece of information, three more pieces of information are optional:

  • Duinocoin username: The name of your own wallet / account - without this information, JavaScript mining makes no sense.
  • Mining threads: The number of mining jobs that are to be started in parallel. This should not be the number of CPU cores or threads (hyperthreading), as this would put the system at full capacity. It is better to leave at least one core/thread unused so that you can still use the system. Trial and error helps: If the system cannot be used during mining or the fan is permanently running at full speed, you should reduce the number of minig threads.
  • Rig Name: You can give each Duinocoin miner its own name. This has technically no effect, but you can better assign each miner and its function in your own wallet.
  • Mining key: If you have activated a mining key in your wallet (a password for your miners), you can enter this password here. This prevents other people from mining for the benefit of their own wallet and influencing the Kolka system or even leading to the deletion of the account due to faulty miners.

Once you have entered all the required information, click on "Start Mining " to start the JavaScript miner.

Yield of the Duinocoin-Webminer

The Duinocoin webminer manages just 0.16 DUCO per day on two cores of a PC workstation.

Tip: The JavaScript miner should only be used when it comes to testing or if you definitely have no other way to mine Duinocoin (DUCO). The JavaScript miner is extremely inefficient, even fast computer systems are quickly completely utilised with it and require a lot of energy, the DUCO yield on the other hand is downright minimal. A test on a HP Z600 workstation with two QuadCore Xeon@2.53 GHz and 48 GByte RAM already caused the CPU fans to run a little faster on two threads (otherwise inaudible) - the Duinocoin wallet showed a yield of 0.16 DUCO per day.
