DUCO - the coin for Arduino & Co.

A wallet is indispensable for the Duinocoin, because it stores your own Duinocoins (DUCO) and enables you to receive and send DUCO..

The Duinocoin wallet is available online on the Duinocoin server. Via an API (programming interface), the wallet can be accessed via own scripts and from applications. The Duinocoin software contains a Python3 script (Wallet.py), but it is not up-to-date.

The Duinocoin is an open-source, centralised and environmentally friendly cryptocurrency for microcontrollers and other low-power computers.

The Duinocoin (DUCO) was originally developed for the Arduino UNO. Its aim is to be a unique cryptocurrency for mining on low-power, low-cost microcontrollers and simple computers. A Raspberry Pi, an Arduino UNO or an ESP8266/ESP32 are all you need to start mining.

If the Duinocoin network is under (too) heavy load or if a comedian has started another DDoS attack, the miners will time out when trying to connect. There is a solution.

Sometimes the pool servers - for whatever reason - do not respond to requests from the miners. On the one hand, this is annoying because at that moment your own miners cannot generate a DUCO. On the other hand, it can also cost a lot of time when troubleshooting your own mining rig, because it is not always clear at first whether the error lies in the software for the rig or with the servers.

To understand a cryptocurrency, you should read its white paper - if it exists at all. For the Duinocoin (DUCO), its inventor has prepared an easy-to-read document.

The Duinocoin (DUCO) was specially developed for the Arduino UNO and uses a SHA1 chain. The Kolka system created by the DUCO developers themselves regulates the difficulty (dufficulty) to reward weak miners fairly. But how exactly does it work?

The Duinocoin (DUCO) is based on a SHA1 hash chain and uses the Kolka system created by the DUCO developers themselves to reward weak miners fairly. How does this work?

With all other cryptocurrencies, miners are rewarded who are as fast as possible, energy-hungry and therefore expensive. Those who use more money get more coins. With Duinocoin, it's the other way around: an Arduino UNO/Nano is the cheapest and most efficient way to mine DUCO.

The development team around Duinocoin inventor Robert Piotrowski (revoxhere) has released version 3.0 of the cryptocurrency tailored for microcontrollers.

Version 3.0 of the Duinocoin software brings more speed to the Arduino Uno, the ESP8266/ESP32 boards and other microcontrollers and thus higher hash rates for mining. There is a fancy, web-based dashboard for the ESP8266/ESP32 and the PC miner manages up to ten times the hash rate thanks to "fasthash".

The video "Best AVR Host For Duino-Coin Mining Rig" by Youtuber and Duinocoin developer "RK Rolling" compares different host systems for Arduino clusters.

JK Rolling runs some benchmarks with mining rigs. Ten Arduino Nano are used as computational nodes for the DUCO-S1 jobs, which are to communicate with the host via I²C or USB. The Raspberry Pi (I²C and USB) and a Wemos D1 Mini (I²C) are used as the host.

After a long break, (m)another attempt starts to move a little online and build a website. Here, on duinocoin.de, it's obviously all about the Duinocoin.

Building a website is of course time-consuming and takes a lot of time and sweat. On the other hand, it's fun - and it helps me and maybe some readers to get deeper into the world of microcontroller mining.

In the video "Build a stand-alone Duino coin mining rig" the Youtuber describes how to build a mining rig consisting of a Raspberry Pi 4, a display and four Raspberry Pi Pico.

The video shows the construction of a very simple mining rig based on a Raspberry Pi 4 - which is completely oversized for this task. Four Raspberry Pi Pico are controlled as mining nodes via a USB hub. The really exciting thing is the holder for the Raspi, the display and the Picos, which I made myself with a 3D printer.

The video "How to Verify Duinocoin / DUCO Wallet" by Youtuber and Duinocoin developer "RK Rolling" shows how to verify your Duinocoin account and thus your wallet.

Here JK Rolling documents the verification process for the Duinocoin wallet.
