TurtleCoin on an ATM

TurtleCoin ATM

GENERAL BYTES, the leading Bitcoin ATM manufacturer from Prague (CZ) and Florida (USA) added TRTL to their range of cryptocurrency ATMs. Operators can now add TurtleCoin to the growing number of ATMs worldwide. We would like to cooperate with the community to make TurtleCoin more accessible to the masses. TRTL is now compatible with all ATMs made since 2013. Please note that although TurtleCoin is supported on the BATM platform this does not automatically mean that operators will support it on their networks. Ideally someone in the community creates an exchange connection so operators will be able to add TRTL to their network even easier. For now we are excited it works and think it will provide value to the TRTL ecosystem.


violetminer for Chukwa


The last week I’ve been working on a miner for the upcoming PoW fork, to argon2id / chukwa. This is mainly for fun, I’m not sure if I’ll be able to match the hashrate of other miner developers.

I’ve wanted to create a miner for some time, and this seemed like a good opportunity as there are not that many miners supporting chukwa yet.

So far, I’ve created an argon2 library, which is not yet optimized, but seems to hash at a not too bad rate regardless. I also created a small cross platform sockets library, to help communicate with the pool software. I started building the miner itself yesterday. I’ve only got pool login working with a hard coded username, but hopefully it won’t require much effort to hook up the hashing library, and I can get to work on optimizing it.

I know the current xmrig miner doesn’t work too well on ARM devices, so maybe I can figure out how to get some ARM intrinsics working to squeeze out a little more performance from them. Intrinsics are pretty new to me, so no promises!

Oh – on an unrelated comment, that TonChan update I was talking for a while went out last week. Hopefully it’s working for you all. Sentry flagged up a couple of bugs, but I think they’re pretty minor ones.



Turtle Rock Paper Scissors is a game boosted with TurtlePay where you can choose between rock paper or scissors to kick the npc machine ass, to start a new game you need to pay the amount of trtl required in the game.
In case that you survive against the npc machine choice then you will appear in the Half Of Fame where your nickname will be showed to the other players.

The project is open source and you can get it here:


Moving Up!

It’s always good to be recognized! These are the people who gained new roles in the community this week!

  • Congratulations to PstarSR and r00tus3r_ for earning their pink Contributor roles this week for their contributions to the organization repositories!
  • r00tus3r_ achieved Developer role, earning a bright pink hat for contributions of code to the organization repositories! Great work!

Good First Issues

Good First Issues are tickets that are marked as ‘easy wins’ for new developers. If you want to be a TurtleCoin Developer, these are great tasks to start with!

  • Use matches property in ApiDispatcher regex
    Some calls in the ApiDispatcher use a regex, we could instead extract hashStr using the matches property on the req object, by adding a capture group to the hash regex
  • Remove no longer relevant asserts
    Since pretty much everyone runs the daemon in release mode, instead of debug mode, we’ve ended up where we have a number of asserts which constantly trigger, due to altered/moved/rewritten sections of code.
  • Daemon+WalletBackend timestamp adjustments 
    The current /getwalletsyncdata rounds a timestamp to midnight. Depending on what time of the day you start a fresh wallet, you may have no blocks to grab (we need to roll back a bit more than we currently do with the timestamp adjustment), or too many (since it’s rounding to midnight which is quite far away).

Rig Of The Week

I’ve been wanting a quad socket setup after doing so many boring sub-$200 dual socket Xeon E5 builds.

I could have saved $100-200 going with a Dell or HP barebones, but noise is a big factor for me. So hashrate per dollar isn’t stellar, but none of my builds are meant to be dedicated miners.

I didn’t have any narrow ILM heatsinks that weren’t 1U, so I borrowed some heatsinks from my other open air setups, modified the unused AMD mounting brackets, and well I guess they’ll do for now. This put me over capacity on that room’s circuit breaker, so those other two machines are turned off now anyway. When I rack it up I’ll grab some Supermicro SNK-P0050AP4.

  • Supermicro X9QRI-F+ motherboard
  • 4 x Xeon E5-4650 V2 (total 40 cores, 80 threads)
  • 16 x 8 GB PC3-12800R (128 GB DDR3 1600 MHz, quad channel)
  • Corsair 850w PSU
  • Whatever cheap 240 GB SSD Fry’s had on sale until I can get this monster into a rackmount chassis with a proper storage array.

Still waiting on E5-4657L v2 to come down in price so I can swap these CPUs out for some 48 core, 96 thread action.

Rotate Discord Server Invite Backgrounds

Discord’s new Nitro Boost stuff allows for Discord owners to choose custom background images when people use the invite links. However it means people have to manually click buttons in the Discord app.

So please head over to and upvote this post to encourage the Discord developers to expose this feature in the Official API. SoreGums

TurtleCoin Github Bot

I’ve been looking into supporting multiple people making an issue at once with the Github bot; it doesn’t seem like it’ll be too hard to add, and it’ll be a nice little perk. If you don’t know what the Github bot is, I recommend you check it out! It lets you easily create a Github issue on any turtlecoin repo w/out an acc; type !tag issue in the #bots channel to learn more



As mentioned last week, I’ve been working on combining the different versions of this repo together. Good news! It’s done.

This repo now builds the following:

1) A c++ static library (Windows, Linux, OSX)
2) A shared library via DLL (Windows) that can be linked against in any number of languages (C# anyone? — @canti, I see you)
3) Node.js native addon module (same as the NPM package before)
4) Native Javascript implementation (slow, very slow, but it works)
5) WASM module for browser use (much, much, much faster than the Native JS in browser)

All of the builds support the core crypto used not only in wallet functions (creating keys, finding our outputs, generating ring signatures, etc) but they also contain all of the hash functions available in core, including Chukwa (Argon2id with our parameters). The WASM module makes it very easy to bring the crypto methods used in TurtleCoin to the browser which will make client-side web wallets faster than ever*. In addition, if someone wanted to build a web miner based on the package they can do so.

Spoiler alert: Someone is building a client-side web wallet built on this using wallet-backend-js.



Using the updates to the turtlecoin-crypto library, I’ve performed a few updates on the development branch of turtlecoin-utils. Most notably, the utils package now smart loads the crypto module. If we can load the Node native addon module, that’s always our first choice. If we’re in browser, then we try to load the WASM first. Lastly, if all else fails, we fall back to the native Javascript implementation. This also has the added benefit of cleaning up a bit of the code that revolves around the crypto in the library.

In addition, due to the exposure of all of the crypto functions in the library now, we’re able to check that the ring signatures that are generated via the library are checked to be valid upon creation thereby reducing the chance of generating an invalid transaction via the library.

If that wasn’t enough, I’ve added a webpack configuration to the project that ties everything up into a nice bundle for inclusion for browser use. Browser use did you say? You betcha. This webpack has been deployed as part of the TurtleCoin Explorer and is used for the tools page (playing with wallet addresses & keys) and the transaction checker. It’s going to make that top secret client-side web wallet shine.”



Over the last week, I have done a lot on the CS-TurtleCoin/CantiLib project. I pushed some major updates, including a full rewrite of the main repo, which features improvements across the board. As I have been fairly silent with the project lately, I’m going to give a quick run-down of what it is and what I have gotten done thus far.

CantiLib is a multi-purpose C# library with many useful tools for a blockchain environment, including a standalone P2P client system, a configurable REST API server, logging utilities, database functionality, cryptography, byte-level serialization, and CryptoNote protocol handling. CS-TurtleCoin is an effort to tie these tools together to create a fully operational TurtleCoin node, coded from the ground up in a C#.

As of the time of writing this, I have P2P connectivity, API handling, CryptoNote deserialization, peer discovery and handshaking, some database functionality, the start of a blockchain cache, and a number of other utilities and functions in place. Lately, my focus has been on refining peer discovery between nodes, porting cryptographic functions from the core code to C#, connecting TurtleCoin-Crypto to the library, adding more functionality and ease of use to the API server, and have also begun work on the sync process and blockchain caching. More to come soon!




This project aims to provide a wrapper for making wallet-api requests with Go. All of the wallet-api responses are marshaled into an appropriate type. You no longer have to manually convert from map[string]interface{}!

If there’s any bugs in the codebase, feel free to leave an issue on GitHub. 😀


TurtleCoin Chukwa Cuvée Testnet available

As everything is in full swing to get ready for the Argon2id-based new TurtleCoin algo called chukwa, we needed to spin up a local testnet.

This allows us to benchmark, test and optimize our different boards, and see how the trtlrig works compared to the native TurtleCoin miner.

We made our test environment available. If you want to see how your harware will do on the new algo, and try out how it feels living on the cutting-edge technology, build your trtlrig from the add_chuwka branch available in the TurtleCoin github, and point your xmrig miner using the following parameters:

-a chukwa
-u your TRTL address

Please note no web front-end available, and no TurtleTestCoin pay-outs. This environment is for benchmark tests only.


34 hot singles in your area are waiting to upgrade your wallet format

Wallet format upgrading

A few people have requested that there be a utility to upgrade a wallet from the WalletGreen format (zedwallet, turtle-service), to the WalletBackend format (zedwallet-beta, wallet-api).

I’ve been working on this for the past few days, and think I am close to completion. Got a few bugs with transfer amounts being incorrect, but hopefully it won’t be a sticking point.

I’m considering adding an automatic upgrade, so you can transparently open an old format wallet and have it upgraded without any user interaction. One downside is that we have to generate the key image for each input when we upgrade the format, which is pretty slow for a large wallet – this can take around 10-20 seconds on my ~8000 transaction wallet.

Of course, this will only have to be done once, so the delay could be worth it.
Hopefully this will make it easier for services to migrate to wallet-api, along with new GUI’s/CLI’s using the new backend.
