This Week In TurtleCoin (May 28, 2019)

In this episode we made it to the papers when over 50,000 system administrators were found to be incompetent (hey ma!) In other news, water also wet.

On the bright side, Home Depot is hiring all positions

Developer Updates

If you’d like to submit your dev update to the roundup, fill out this form



Good news! I spent a bit of time over the holiday weekend and wired up the xmrig fork trtlrig to support Chukwa (Argon2id) CPU pool mining. I’ve tested it on Windows and a few different flavors of *nix. @LeoCuvée also mentioned that he tested it on ARM. Overall, it’s ready to go but I’m sure that someone will come around and fine a few enhancements to squeeze a bit more hashrate out of it but it’s an awesome start.

As part of testing trtlrig, I verified that all of the necessary updates for turtle-pool are complete for Chukwa. Everything needed has been merged into the development branch if you’d like to set up a testnet and pool for testing yourself.

Successfull build and test of the Chukwa TRTLrig on SBC

Successfull build and test of the Chukwa TRTLrig on SBC

In the past few days, we managed compile and test the TRTLrig for the Argon2id Chukwa algo which TurtleCoin will fork to at block 1,800,000.

For our testing, we have used slightly different parameters than those that will be used by TurtleCoin (512kb memory, 3 iterations).

For our test, we worked together with @CapEtn of WRKZCoin, which will use 256kb memory and 4 iterations. Results?

Partly pleasing, partly requiring further optimizations.

The RK3328 chip that runs the Rock64 boards (which we use for our SBC nodes) gets a very nice bump. The increase is from underperforming slow 310 h/s on cryptonight-turtle to 550 h/s on Chukwa 256/4.

We also tested on the cryptonight-turtle best performer OrangePI One Plus, which is based on the Allwinner H6. Unfortunately, we could not seem to get any increase in hash rate on Chukwa 256/4 for this board, quite the opposite.

The OrangePI One Plus that otherwise excells on cryptonight-turtle (750 h/s) and actually does less on chukwa 256/4, specifically 623 h/s, no matter what we tried so far.

Well, there is a room for improvement! Slow & steady!


Wallet sync speed improvements

Wallet sync speed improvements

As mentioned last roundup, I planned on working on multi-threading the sync process for wallets. This has now been completed and merged, and has given some decent speed gains.

Wallet syncing should now scale up to the number of cores you have (Provided you’re using the latest code and either wallet-api or zedwallet-beta). We’re now bottlenecked solely on how fast we can retrieve blocks from the daemon. Because of this, we don’t see huge increases in speed — as most of the time, we’re just waiting for more blocks rather than using all our threads.

However, if you have a less powerful device that previously was CPU bottlenecked — For example, a raspberry pi or other SBC, this should result in some more significant speed improvements.

Unfortunately, when using a remote daemon, threading does very little in terms of increasing sync speeds. This is a good reason to run a local daemon, especially on an SSD, if you want your wallet to sync super quick!

As you can see from the image above, with 12 threads and a local daemon, you can sync a wallet with over 10k transactions in under an hour.

Some advancement has been made on the stand alone crypto module that includes all of the necessary code in a nice, tight, static library for performing any crypto/hash related functions used within the Core project.

  1. Implemented a wrapper that passes all data into and out of the methods as strings to make it easier to link up to the library instead of having to carry a whole bunch of structs around.
  2. Added Chukwa support
  3. Improved Windows build process so that it creates a shared library (.dll) with the export definitions defined so that it can be linked against by other projects “easily”. See #dev_canticore for it’s first use (when he’s ready).
  4. Working to combine all of the turtlecoin-crypto repos (JS/Node.js/WASM) library builds into a single repo.
  5. Much, much, more.

turtlecoin-multi-hashing & turtlecoin-cryptonote-util

Again, to support trtlrig & pool testing for Chukwa, the Node.js turtlecoin-multi-hashing & turtlecoin-cryptonote-util packages heavily used by pools and the like have been updated to support Chukwa (Argon2id). This package has been published to NPM and GitHub and is ready for widespread use.

Dockerized TurtleCoin with TTYD

Dockerized TurtleCoin with TTYD

I recently came across a cool program called TTYD that shares a terminal with the web and decided to integrate it into my docker projects. I initially started with TurtleCoind and, after realizing how easy easy it was, quickly moved on to zedwallet. Once those two were completed I was able to create a docker-compose file that spun up both services on the same network, allowing you to view the TurtleCoind output and interact with zedwallet via a browser. At this point I was kind of taken with TTYD and decided to start containerizing some of the other terminal based community projects using this new (to me at least) shiny toy.

Words don’t really do this any justice. If you’re familiar with Docker and want to see it in action, jump to the run commands down below. If, on the other hand, you’ve been pushing off learning Docker, never understood what the hype is about, or never heard of it? Stop right now and go download it here. Seriously, go do it, I’ll wait. And while you’re at it install Docker Compose too. In the meantime, I’ll gush about some of the things that I think makes Docker cool.

Docker containers are standardized so we don’t need to worry about our environment, like finding and installing the right libraries on our host machine, to get the software up and running. They are portable and reusable in the sense that they can be easily pulled, started, stopped, or removed when needed (which is great for trying out new software). We can run multiple containers and allow them to communicate and share data with each other over isolated networks. We are able to mount files/folders located on the host within our containers which makes development easier. The list goes on, but enough of my fanboying let’s get started.

Now that you have Docker installed let’s spin up a container that runs TurtleCoind. Open up your terminal and run:

docker run -d -p 7681:7681 -p 11897:11897 --name turtlecoind-ttyd -v turtlecoind:/home/turtlecoin/ andrewnk/turtlecoin:turtlecoind-ttyd

Now access http://localhost:7681. After a few moments, you should see a terminal pop up and the familiar output of the TurtelCoind daemon.

But what about zedwallet, you say? Try it out with this command:

docker run -d -p 7682:7681 --name zedwallet-ttyd -v turtlecoind:/home/turtlecoin/ andrewnk/turtlecoin:zedwallet-ttyd

Then access http://localhost:7682.

Pretty cool, right? Using this setup we won’t be able to actually use zedwallet though, because we haven’t provided a node for it to connect to. Before moving on, remove both containers we just created, by running the command:

docker rm -f turtlecoind-ttyd zedwallet-ttyd

Using Docker Compose we are now going to run both containers connected to each other on an isolated network and accessible via the browser.

First you need to save the file that contains the “instructions”, then use docker-compose to spin everything up. Download this docker-compose.yml file and save it as docker-compose.yml. Then in your terminal navigate to the file and run:

docker-compose up -d

Once everything is up and running you can navigate to http://localhost:8080 to see TurtleCoind and to http://localhost:8181 to use zedwallet. You are now running the daemon and can use zedwallet as you normally would. In this instance all the data (TurtleCoind and zedwallet files) will be stored in a folder, created by the containers, on your host machine titled turtlecoin.

When you’re done playing you can destroy the containers and network by running:

docker-compose down

This is just a quick overview of what can be done. Each image can accept a wide array of variables to customize your container.

So far, I have created TTYD images for:

  • miner
  • Turtle CLI py
  • Turtle Network CLI
  • TurtleCoin Test Suite
  • TurtleCoin Wallet NodeJS (Divine)
  • TurtleCoind
  • TurtleCoind HA
  • zedwallet
