Hey, so to be honest I'd like to apologize - Kolka rewards haven't been working correctly for a few weeks or even months.
Since Bilaboz is working on (yet another!) database migration on the main server which should make it even smoother, I thought I will take a look at the kolka % drop issues you guys reported in the forms created by Yennefer.
After I did some testing with multiple miners the results were way off from the expected numbers.
I pushed a few changes (really small - no wonder I didn't notice them earlier!) to the pools code an now it seems to work properly. I'm currently updating all the nodes I have access to (all excluding diskos and dream, they will take a bit longer to update) that should, at least mostly, fix the kolka issues.
Sorry for that, I'll also take a look at other issues asap.

A few short updates Transactions from faucets and bots will now use xxhash hashes instead of sha1 to save space - 40 bytes is really a lot for non-important transactions when we take into consideration a few transactions a minute sometimes.
As many of you also noticed, you can now use the item shop inside the Web Wallet (which also should be more optimized and work better since a few days) in which you will be able to buy various items and services that will change some things about your Duino-Coin account. For now the changes are only cosmetic but soon we will introduce buyable kolka upgrades and similar stuff (we're open for suggestions!).
Since I'm already here, it's worth noting that release 3.1 (or 3.2, depends) will be released in the upcoming weeks, aiming to provide even more security with mining. Many of you probably saw that there's not much development going on lately, but you should know that we also have school and/or work to take care of first; also - if something works well enough there's no need to change it - for now.
Have a good day/night!

You can now setup a separate mining password (key) for better security. Read more about it in the my miners section in your web wallet. This is not a breaking change - older miners can specify their password in the rig name after a colon (:) and setting a mining key is not required, although recommended.

Infos Hey everyone! Long time no see, huh?
Firstly, wanted to let you all know officially that we support Ukraine and we will try to help much as we can when it helps to helping them even by donating, but we won't be blocking any countries anymore as Duino-Coin is meant to be for everyone and "regular" people are not to blame for the conflict.
Second, we know the russian-speaking Duino community always had trouble organizing in the english channels of our Discord and many unofficial groups appeared. This lead to spreading misinformation or falling into scams these groups made, so with the kindness of Dechimmo and a few other users, we decided to make their server an official place for russian speaking users:
Next thing - as some of you probably saw already, revox introduced Duino staking yesterday. You can freeze your DUCOs to earn passive rewards; this process helps in controlling the coin circulation, the effects of which should become clear in the future. See the online wallet for more info.
Last but not least, we'd like to apologize for not much going on with the development lately, but we all are pretty busy with school and work. This doesn't mean new things aren't coming - we are preparing some Kolka updates, Internet of Things integrations, Coin Magi updates and other various improvements.
That's it for now, stay safe and have a great day!

Happy valentine's day! Hello everyone! What a lovely day today πŸ˜„
We'd like to announce that ducopay by @issechan is ready to be used in alpha state. It's a payment gateway for Duino (something like PayPal) that allows easy payment integrations. Read more about it here.
Second thing we'd like to share is a new user to user, decentralized exchange - Furime P2P by @Furim. You can trade duino and tron (and soon nano) with other users. No limits, no fixed prices - have fun:
Lastly, the whole Duino-Coin Team wishes you all a happy valentine's day, whether you celebrate it with someone or alone, you can always take part in a new giveaway starting in 🎁-giveaways channel of or Discord soon πŸ₯°
P.S. Node-S exchange is shutting down as @Connor2 (the Node-S owner) does not have enough time to focus on it. Please withdraw your DUCO from it as soon as possible.

Latest informations Thanks everyone who wished me happy birthday - I really appreciate it! I hope stuff won't get too difficult since I'm 18 now, but we will see.
As announced, since yesterday, the 2.X miners are deprecated.
Ldarki has recently added a session token instead of passwords to stop you guys complaining that they're stored inside cookies. As a result you need to unfortunately login every hour. I still don't know what was wrong with the previous method and I never received a good response from anyone complaining, but oh well.
Info from Yanis, the tokenized DUCO chains maintainer: bscDUCO now has a wrap fee (and minimum wrap) of 500 DUCO, which is meant to cover operating costs (over the last year we spent over 1000$ paying YOUR fees). If you try to wrap an amount BELOW 500 DUCO, it will be returned to your account.
Furim has recently released a beta version of his chat app based on Duino-Coin -

Release 3.0 is out Huge release 3.0 is finally out. It includes a lot of performance improvements in comparison to the 2.X version, for example a Raspberry Pi 4 should now achieve up to 9 MH/s, an Arduino performs 220 H/s, ESP boards self-host a mini dashboard for quick health checks, etc. Full changelog and download links are available on GitHub.
Note: upgrading to this release is required. Servers will stop accepting version 2.X miners in a few weeks.

Beware of fake Duino-Coin profiles Since we're getting more and more popular, more phishing and Duino impersionation attempts show up. Plase be warned that the only official Duino social media are Reddit, Discord and Twitter.
For example, there's a russian Instagram account that is sending other people's photos from Discord, promoting some NFT scams and even saying Duino-Coin was created by them.
I have reached out to them to ask why they're publishing other people content and making it seem like it's an official account, as a response he told me he's advertising duino and I should be thankful he doesn't want anything in return.
I suggest reporting them πŸ€·β€β™€οΈ πŸ‘‰
Edit: as @SprinteR suggested, a good option may be for people who posted on mining-rigs channel to report him for using their photos without permission

Possible API issues We are aware of the periodic inacessibility of duino coin APIs last days, this is because we're gaining popularity faster than we can keep up, but we're doing what we can.
Yesterday I made the API load balanced with multiple servers which should, once working correctly, help a lot with the performance.
If anyone is concerned about mining - pools are separate servers and they will always retry to sync your mining rewards as soon as they can.
Release 3.0 may be delayed by a few days as I'm still waiting for my ESP32 to arrive - I need to work on something for it myself. If this will be taking too long, we will release version 2.9 with just the Raspberry Pi buffs.
Sorry for all problems and thanks for understanding! ❀️

Goodbye 2021! Thanks everyone for really amazing 2021, Duino expanded like never before - we started the year will just over a thousand members and now we're at 30 times more, same with Discord members.
We got listed on SunSwap, PancakeSwap and SushiSwap; had loooots of tough situations to go through and problems to solve, but the best thing is we learned a lot thanks to them.
Duino will be three years old in the upcoming year, and the fact it's doing better than ever overall still blows my mind.
While I'm on it, I'd also like to thank everyone from the administration for constant help, care and support - it's better together!
I'll be hosting a giveaway in the #🎁-giveaways channel on Discord, for now that's it, but prepare for strong start of the new year :3

Bounties for bug finders (and bug fixers) As we announced some time ago, we're starting the bounty project for anyone that can find issues or fix them. We also think it's a great accomplishment you will be able to flex with, so check if you see anything that can be improved. If you will do well, we may even invite you to the development team.
What's rewarded?
- serious bugs or issues that can lead to potential security faults or other harmful situations (Mostly node/pool codes)
- less important software bugs (PC Miner, AVR Miner, wallets) that make using duco less enjoyable
- missing documentation, inconsistent translations, site improvements - anything that could be improved
- any issue you fix by submitting a pull request/commit (that is 'good' quality) will also be get rewarded
- well described feature requests or possible improvements
How to organize the issues?
Use our GitHub repository for submitting issues and pull requests. Make sure you include you DUCO username and tell that you're taking part in the bounty. You can ping me or other devs on GitHub so I can review the changes and reward you.
What are the rewards?
Depending on how serious the issue is (or the quality of your fix for it) we will be sending 5 to 5000 DUCO to each participant.
Happy developing!

I also got some that the voting for Duino-Coin getting listed on has been accepted, which sounds cool - we will wait for more updates πŸ’°. I also prepared a list for myself of things to do and expand in the next weeks related to Duino, because all these random scenarios that happened lately kinda threw me out of my work rhytm πŸ“‹.

bscDUCO and maticDUCO
I've received some messages that bscDUCO and maticDUCO wraps do not work. It's most probably because the wrapper ran out of funds to pay the transaction fees. Developer responsible of wrappedDUCO chains development has been already notified and he should take care of it soon. From what I know, all pending wraps should complete once the wrappers get refilled.

Things should be more or less operational
It looks like the DDoS attack has stopped. As with all similar situations, we have learned a lot, which should help us in the future. I know some services (e.g. pulse-pool) haven't recovered fully yet, but everything should be back soon (during the upcoming days as we are strenghtening the security settings). Let's hope it goes well, thanks to everyone who helped us on Discord! P.S. - I know pools may not sync the workers, this should be fixed soon. I'm assuring that earnings go to your wallets (the sync data for earnings and workers is separate).

Exchange rates have been decreased
Because we run too fast out of liquidity (thank big sellers) we had to decrease the exchange rates on DUCO Exchange (temporarily). One solution to this problem may be to bring back the donation feature in the miners, we will see.

Voting ended with photo verification as a chosen vote (3/09/21)
Because of the ever going cheater problem, with the help of community, we've come up with two possible ideas on stopping them:
1. Make the AVR and ESP codes fully closed source (we would only ship the .bin files), no user modification available.
OR 2. Require a photo verification (somewhere in the wallet) of your rig before you can start mining on anything other than a PC, source codes would be kept fully public.
Vote which one would be better to implement on our Discord in the #announcements channel.

revox 31/08/21 10:03

Release 2.7 is out with AVR mining experimentally enabled again, we will see if there will be any more issues. Get it here. If your PC/ESP miners are working fine there's no need to update.

revox 30/08/21 00:51

I added QuickExchange support to DUCO-BCH and TRX pair on duco exchange for selling. Let me know it there will be any issues. I also re-made some e-mail messages we send and I'll try to fix the ESP32 reward problem (in a few minutes). You can also now browse the miners and transactions in the explorer, although I'm still not satisfied with this look and will probably change it soon πŸ˜›

I think you prefer losing a few ducos instead of having all the supply inflated with the almost 2.000.000 duco.
Mining will be disabled until we figure out what happened with presumably one of the pools β›οΈπŸš«
Shut down your miners to not waste electricity and wait until the situation stabilizes πŸ”Œ

revox 23/08/21 20:09

Reward change I had to change the rewards to logarythmic, meaning that Arduinos no longer earn the most, neither do ESPs. Why was it needed? Someone does not get the point in this project and is trying to break everything - you can thank him. Will that stay? I don't know - see my message below. And also, don't forget to call me a scammer, because of course I earn tons of money from that project. I wish we did any. Like for real, I don't even have a bank account because I'm 17 and there's none in my village. Anyway, I will need someone with ideas on what to do

revox 22/08/21 22:58

Help It's already fixed and does not have relation with any overloading since we have quite a few pools now. I just wanted to say that it's really hard for me to keep everything even running, there's constant work and I'm starting to go crazy + there are more and more people that do not get the point, even after adding a clear statement on the main website. I'm starting to really regret making this because of time wasted trying to please everyone. Can anyone suggest me what to do

revox 22/08/21 21:39

Sync issues should be fixed Last two days we were busy figuring out what's going on with some of the pools not syncing with the master server properly. This should be now fixed, although I'll still be actively watching the situation to see how things go on and push fixes as needed.
I'd also like to thank you all, because all these problems come just because we're growing really really fast and it's still a shock for me to see Duino being so successful. We have recently passed 20.000 registered accounts and 4000 members on Discord which is just awesome. I'll be hosting some competitions soon!

revox 19/08/21 22:07

ESP32 code with automatic pool fetching Similarly to the ESP8266, the ESP32 can now automatically fetch the best pool. Please read the news below for further explaination. Here's the link to the new ESP32 code

revox 17/08/21 11:05

Important ESP8266 code update I think I've finally found the cause of the sync problems, and that is the way nodejs handles thread switching, which is quite different than python and that causes the node to struggle with finding time to sync when there are lots of clients coming at once. Since all ESP8266s and 32s have the port 6000 hard-coded instead of using the /getPool API request, the pool is bombarded with constant requests and can't sync even once. I didn't think it would be a problem at first, but time showed that it is, so I've updated the ESP8266 code on GitHub to get the least loaded pool automatically (just like the AVR and PC miner do it). For that I used a part of @ricaun's code, so big thanks for him.
TL:DR: Any ESP8266 miners that have issues with connecting to the pool, please upload the new code to their boards (or wait until the majority of people moves to other pools and the 6000 port will be less crowded once again). Here's the link to the new ESP8266 code

22/07/21 18:04: Mining rig contest winners

The competition has come to an end with 17 winners, view their rigs here. I hope that was fun, we may do more contests soon.


20/07/21 11:52: Mining rig contest 🏁

There's 2k DUCO left gathered from Kolka so I decided to organize a contest - post your mining rig in the #πŸ“Έ-mining-rigs channel in our Discord server, I will choose the best looking and the most power-friendly one in a few days. Winner gets juicy 2000 DUCO πŸ˜‰ Results will be announced here and on the Discord.


18/07/21 18:57: Duino-Coin store is out πŸ₯‚

Hello everyone, we've released a store in which you can buy official Duino merch πŸ‘•


16/07/21 10:27: Review us

Hey, how's everyone doing? While browsing the internet today I've seen that for some reason we have a very low trust score, so I encourage to honestly review us: and Thanks in advance 🧑🧑 Rewards should be fixed now, and more cool stuff coming soon πŸ‘€


14/07/21 16:51: Site updates

Hey, yes it's me, firstly, I'm really thankful to everyone who messaged me in the last days, I know I need to change the way I care about some people and I'll try to take notes from some tips I've received. Today I managed to refresh the explorer page (, webwallet ( and also DUCO exchange is back online ( - but please don't spam me with too many requests 😊 I'm planning to increase the BCH exchange rates soon. Have a good day everyone!


13/07/21 18:43:

Over the past two days I received numerous private messages and e-mails saying that it's better when I'm in the dev team. They were accompanied with lots of kind words and I probably haven't responded yet to everyone - about that I'm really sorry, but I read everything - sometimes maybe too much. I was really thinking that maybe after some changes in the way we work and better planning, I would be able to return and we would be further pushing with the development, but today I'm really hopeless. I hear that I care too much, and maybe it's right, but I just want good for everyone. Anyone wanting to know why all of this is happening, here are some of the reasons: I have no clue what to do anymore. Private life doesn't help. A lot of work went into Duino and looks like it's still isn't enough for people to appreciate it.


11/07/21 22:32:

I'm really thinking of leaving. I cannot stand the constant hate from various persons. When I think about it, they're probably right. I don't know who wants to take this project further, I guess someone from the current administration. I guess someone else would take care of this better than me. DUCO Exchange and development won't be present from my side until I decide what to do. Remember, "I'm cringe"


11/07/21 14:10: New release: 2.5.6

Release 2.5.6 is out with some improvements especially for AVR mining. Update isn't required but I encourage to do so. Get it here: release 2.5.6

6/07/21 21:00: New release: 2.5.5 (Pools are here)

New release is out featuring additional nodes for PC & ESP mining, get the new version here: release 2.5.5


6/07/21 14:02: First pool is open

First pool is now open and can be accessed by using the latest pc miner from github - let's test it :p Please let us know it you encounter any issues. Update: Release 2.5.5 will be released this evening (in a few hours) with the PC miner and ESP codes supporting the pools AVR mining willl stay on the master server because of rquired strict Kolka implementations

revox & Bilaboz

6/07/21 01:18: Pools

We just finished testing first pool with Bilaboz and it all seems to work fine - if all things go well tomorrow (actually today, but it's 1 AM) we will launch it for public (actually some users of the newest miner from git tested it probably without knowing! :P)


4/07/21 22:00: Updates

We're still working on the server and finishing up the pools (last part of the master server addon is being finished by Bilaboz), the first pool will be hosted on the new vps and take the load coming from pc miners and possible later also from esp miners. Anyone wanting to help with programming should contact revox or bila on discord.


3/07/21 23:55: ESP8266 and ESP32 (again...)

Anyone having problems with ESP mining should try the new codes as a temporary fix while we wait for the pools: ESP8266 ESP32 Peace!


3/07/21 18:35: Webwallet update

Webwallet has been updated to retrieve the data faster. As always, please report any new problems on our Discord. More info about pools and VPS soon.


1/07/21 23:30: New release: 2.5.2

PC Miner users should try the latest Release 2.5.2 that implements port shuffling (YeahNotSewerSide's idea) for better connection. Raspberry Pi users can just type git pull in their terminal to automatically update.
Other than that, we're soon moving to a bit bigger VPS server and also we're expecting to launch the pool system. Big thanks to everyone who donated!


1/07/21 15:00: New Duino-Coin video by The Common Channel


28/06/21 17:30: ESP8266 and ESP32 mining

All ESP8266 and ESP32 miners are advised to upload 2.5.1 code to their boards to fix the connection issues. Other users (AVR, PC, etc.) don't need to do anything - the release is the same as 2.5. Download release 2.5.1


27/06/21: New release: 2.5 (Hotfix)

All PC and AVR miners, please update to version 2.5 to (hopefully) get some more stability. There's so little I can do without the pools being finished, but I hope it helps. Download release 2.5

25/06/21: Update!

Mining should work more or less without problems now. We're still not finished with doing all the changes but we will do them some time later. We also decided to add a small, unobtrusive advertisement in the web wallet and miner to help us cover the costs. We can't keep spending our own money onto the project forever, right?


24/06/21: Migration

We are starting with the final steps of the server migration. Servers are going down now for the next hour or two, please don't make any transactions. There are some issues with the configuration.


23/06/21: Another update

We're done with creating the new master node and almost done with the new REST API. We may temporarily open port 2811 for some quick tests but the mining earnings won't be saved yet. We should be able to finish it by tomorrow 20:00 UTC. More informations - as usual - will be coming soon, here and on our Discord


22/06/21: Updates

So, because of the issues we had to disable all mining to make the wallets still available. It's a difficult sitation for everyone, but as you can see a lot of people are working on fixing it. It's (as usual) my fault - I never thought of scalability (I never thought Duino would have more than 100 members). I'm sorry I fucked up with this but we're just expanding very fast. Thanks for your patience - database migrations should be finished by today or tommorow.


20/06/21: Possible accessibility issues

Server is currently being worked on (mainly by Connor), this includes database migrations and other operations that may cause it to be unstable while we're fixing the high load. Also please note that the worker limit has been temporarily set to 12 workers and the whitepaper will be soon updated to be a bit more descriptive. As always, we will keep you guys updated here and on our Discord.


17/06/21: Raspberry Pi & PC mining back online

Since I had some time today, I've managed to add caching into the rest api that made the load drop enough to re-enable lower difficulties of mining. The rewards and difficulties for Raspberry Pis aren't fully finished yet, but I'll work on them in the upcoming days. Have fun mining!


15/06/21: New Duino-Coin video by Ted Gets Bread


8/06/21: PC mining temporarily disabled

And so I'm back. Maybe some people don't like to hear this, but I'm here as it's MY project and I will take care of it. Anyway, the most important thing to tell you is that PC mining has been temporarily disabled. We'll re-enable it again probably once pools will be relased. For now, enjoy the low-power mining. Cya later, and also thanks to everyone for telling some kinds words.


6/06/21: I think I'm leaving

I'm taking a break. Peace. 7/06: No - this is not the end - because I received some messages questioning that. I'm coming back, of course when other admins will want me still. Almost all I hear are complains. People expect too much from me. I'm just not fucking enough for this. So there you go, see for yourself how easy it is do to all of this. I hope you also have school and private life like me to take care of. Honestly good luck combining these two things.


30/05/21: Possible accessibility issues

Hey there, we are aware that the server was "offline" for a few hours second time in a row, we're not sure what's causing it as there are no obvious error messages or anything. I'll keep looking, and possibly do some quick restarts shortly. Nothing to worry about.

20/05/21: Server latency improvements

Hello, I had some time today and optimized a few things in the server that should improve the ping and overall responsiveness.
Happy mining!

12/05/21: OpenCL miner update & some news

Hey there!
If you've read the latest news, you know an OpenCL miner is in the works - I'm writing to tell that our team has managed to beat nonceMiner (fastest DUCO-S1 miner until now) in terms of speed at hashing on CPU. This doesn't mean that people using nonceMiner or the upcoming OpenCL miner earn more (Kolka system gives the miners very big difficulty to mine), it's just to show the speed. Sorry for not doing a lot of development myself lately - I have quite a lot of school stuff to do, but I'm doing what I can to fix things asap. p.s. - I hope you like the slightly refreshed wallet look.


10/05/21: Upcoming changes

Hello again!
I wanted to shortly explain what we're working on currently: firstly, YeahNotSewerSide and JoyBed are doing a great job making Duino-Coin OpenCL Miner that will allow mining on CPUs and GPUs (AVR mining stays the same). In the meantime dansinclair25 and I are working on a new API to reduce the network load. Bilaboz is making the pool system and soon we'll start work on refreshing the GUI Wallet (LDarki & HGEpro). Also we have a new dev for AVR stuff: joaquinbvw and Pripun for mobile apps - welcome!


09/05/21: Web Wallet 2.5.3

Hello everyone!
Web Wallet has been recently updated to include some new features and fix some issues.


09/05/21: Is this working?
