Code your own blockchain mining algorithm in Go!

With all the recent craze in Bitcoin and Ethereum mining it's easy to wonder what the fuss is all about. For newcomers to this space, they hear wild stories of people filling up warehouses with GPUs making millions of dollars worth of cryptocurrencies a month. What exactly is cryptocurrency mining? How does it work? How can I try coding my own mining algorithm?
We'll walk you through each of these q uestions in this post, culminating in a tutorial on how to code your own mining algorithm. The algorithm we'll be showing you is called Proof of Work , which is the foundation to Bitcoin and Ethereum, the two most popular cryptocurrencies. Don't worry, we'll explain how that works shortly.
Cryptocurrencies need to have scarcity in order to be valuable. If anyone could produce as many Bitcoin as they wanted at anytime, Bitcoin would be worthless as a currency (wait, doesn't the Federal Reserve do this? *facepalm*). The Bitcoin algorithm releases some Bitcoin to a winning member of its network every 10 minutes, with a maximum supply to be reached in about 122 years. This release schedule also controls inflation to a certain extent, since the entire fixed supply isn't released at the beginning. More are slowly released over time.
The process by which a winner is determined and given Bitcoin requires the winner to have done some "work", and competed with others who were also doing the work. This process is called mining , because it's analogous to a gold miner spending some time doing work and eventually (and hopefully) finding a bit of gold.
The Bitcoin algorithm forces participants, or nodes, to do this work and compete with each other to ensure Bitcoin aren't released too quickly.
A quick Google search of "how does Bitcoin mining work?" fills your results with a multitude of pages explaining that Bitcoin mining asks a node (you, or your computer) to solve a hard math problem . While technically true, simply calling it a "math" problem is incredibly hand-wavy and hackneyed. How mining works under the hood is a lot of fun to understand. We'll need to understand a bit of cryptography and hashing to learn how mining works.
A brief introduction to cryptographic hashes.
One-way cryptography takes in a human readable input like "Hello world" and applies a function to it (i.e. the math problem) to produce an indecipherable output. These functions (or algorithms) vary in nature and complexity. The more complicated the algorithm, the harder it is to reverse engineer. Thus, cryptographic algorithms are very powerful in securing things like user passwords and military codes.
Let's take a look at an example of SHA-256, a popular cryptographic algorithm. This hashing website lets you easily calculate SHA-256 hashes. Let's hash "Hello world" and see what we get:
Try hashing "Hello world" over and over again. You get the same hash every time. In programming getting the same result again and again given the same input is called idempotency .
A fundamental property of cryptographic algorithms is that they should be extremely hard to reverse engineer to find the input, but extremely easy to verify the output. For example, using the SHA-256 hash above, it should be trivial for someone else to apply the SHA-256 hash algorithm to "Hello world" to check that it indeed produces the same resultant hash, but it should be very hard to take the resultant hash and get "Hello world" from it. This is why this type of cryptography is called one way .
Bitcoin uses Double SHA-256 , which is simply applying SHA-256 again to the SHA-256 hash of "Hello world". For our examples throughout this tutorial we'll just use SHA-256.
Now that we understand what cryptography is, we can get back to cryptocurrency mining. Bitcoin needs to find some way to make participants who want to earn Bitcoin "work" so Bitcoins aren't released too quickly. Bitcoin achieves this by making the participants hash many combinations of letters and numbers until the resulting hash contains a specific number of leading "0"s.
For example, go back to the hash website and hash "886". It produces a hash with 3 zeros as a prefix.
But how did we know that "886" produced something with 3 zeros? That's the point. Before writing this blog, we didn't . In theory, we would have had to work through a whole bunch combinations of letters and numbers and tested the results until we got one that matched the 3 zeros requirement. To give you a simple example, we already worked in advance to realize the hash of "886" produced 3 leading zeros.
The fact that anyone can easily check that "886" produces something with 3 leading zeros proves that we did the grunt work of testing and checking a large combination of letters and numbers to get to this result. So if I'm the first one who got this result, I would have earned the Bitcoin by proving I did this work -- the proof is that anyone can quickly check that "886" produces the number of zeros I claim it does. This is why the Bitcoin consensus algorithm is called Proof-of-Work .

But what if I just got lucky and I got the 3 leading zeros on my first try? This is extremely unlikely and the occasional node that successfully mines a block (proves that they did the work) on their first try is outweighed by millions of others who had to work extra to find the desired hash. Go ahead and try it. Type in any other combination of letters and numbers in the hash website. We bet you won't get 3 leading zeros.
Bitcoin's requirements are a bit more complex than this (many more leading zeros!) and it is able to adjust the requirements dynamically to make sure the work required isn't too easy or too hard. Remember, it aims to release Bitcoin every 10 minutes so if too many people are mining, it needs to make the proof of work harder to compensate. This is called adjusting the difficulty . For our purposes, adjusting the difficulty will just mean requiring more leading zeros.
So you can see the Bitcoin consensus algorithm is much more interesting than just "solving a math problem"!
Enough background. Let's get coding!
Now that we have the background we need, let's build our own Blockchain program with a Proof-of-Work algorithm. We'll write it in Go because we use it here at Coral Health and frankly, it's awesome.
Before proceeding, we recommend reading our original blog post, Code your own blockchain in less than 200 lines of Go! It's not a requirement but some of the examples below we'll be running through quickly. Refer to the original post if you need more detail. If you're already familiar with this original post, skip to the "Proof of Work" section below.
We'll have a Go server, where for simplicity we'll put all our code in a single main.go file. This file will provide us all the blockchain logic we need (including Proof of Work) and will contain all the handlers for our REST APIs. This blockchain data is immutable; we only need GET and POST requests. We'll make requests through the browser to view the data through GET and we'll use Postman to POST new blocks ( curl works fine too).
Let's start with our standard imports. Make sure to grab the following packages with go get.
github.com/davecgh/go-spew/spew pretty prints your blockchain in Terminal.
github.com/gorilla/mux a convenience layer for wiring up your web server.
github.com/joho/godotenv read your environmental variables from a .env file in your root directory.
Let's create a .env file in our root directory that just stores one environment variable that we'll need later. Put one line in your .env file: ADDR=8080.
Make your package declaration and define your imports in main.go in your root directory:
If you read our original article, you'll remember this diagram. Blocks in a blockchain are verified by comparing the previous hash in a block against the hash of the previous block. This is how the integrity of the blockchain is preserved and how a malicious party can't change the history of the blockchain.
BPM is your pulse rate, or beats per minute. We'll be using the beats per minute of your pulse as the data we put in our blocks. Just put two fingers on the inside of your wrist and count how many times you get a beat in a minute, and remember this number.
Some basic plumbing.
Let's add our data model and other variables we'll need under our imports in main.go.
difficulty is a constant that defines the number of 0s we want leading the hash. The more zeros we have to get, the harder it is to find the correct hash. We'll just start with 1 zero.
Block is the data model of each block. Don't worry about Nonce , we'll explain that shortly.
Blockchain is a slice of Block which represents our full chain.
Message is what we'll send in to generate a new Block using a POST request in our REST API.
We're declaring a mutex that we'll use later to prevent data races and make sure blocks aren't generated at the same time.
Let's quickly wire up our web server. Let's create a run function that we'll call from main later that scaffolds our server. We'll also declare our routes handlers in makeMuxRouter() . Remember, all we need are GET to retrieve the blockchain, and POST to add new blocks. Blockchains are immutable so we don't need to edit or delete.
The httpAddr := os.Getenv("ADDR") will pull port :8080 from our .env file we created earlier. We'll be able to access our app through http://localhost:8080 in our browser.
Let's write our GET handler to print our blockchain to our browser. We'll also add a quick respondwithJSON function that gives us back error messages in JSON format if any of our API calls produces an error.
Remember, if we're going a bit too quickly, please refer to our original post that explains each of these steps in more detail.
Now we write our POST handler. This is how we add new blocks. We make a POST request using Postman by sending a JSON body e.g. to http://localhost:8080 with your pulse rate you took earlier.
Note the mutex lock and unlock. We need to lock it before writing a new block, or else multiple writes will create a data race. The perceptive reader will notice the generateBlock function. This is our key function that will handle our Proof of Work. We'll get to it shortly.
Basic blockchain functions.
Let's wire up our basic blockchain functions before we hit Proof of Work. We'll add a isBlockValid function that makes sure our indices are incrementing correctly and our PrevHash of our current block and Hash of the previous block match.
We'll also add a calculateHash function that generates the hashes we need to create Hash and PrevHash . This is just a SHA-256 hash of our concatenated index, timestamp, BPM, previous hash and Nonce (we'll explain what that is in a second).
Let's get to the mining algorithm, or Proof of Work. We want to make sure the Proof of Work is complete before we'll allow a new Block to get added to the blockchain . Let's start off with a simple function that checks if the hash generated during our Proof of Work meets the requirements we set out.

Our requirements will be as follows:
The hash that is generated by our Proof of Work must start with a specific number of zeros The number of zeros is determined by the constant difficulty that we defined at the start of our program (in our case, 1) We can make the Proof of Work harder to solve by increasing the difficulty.
Write up this function, isHashValid :
Go provides convenient Repeat and HasPrefix functions in its strings package. We define the variable prefix as a repeat of zeros defined by our difficulty . Then we check if the hash starts with those zeros and return True if it does and False if it doesn't.
Now let's create our generateBlock function.
We create a newBlock that takes the hash of the previous block and puts it in PrevHash to make sure we have continuity in our blockchain. Most of the other fields should be apparent:
Index increments Timestamp is the string representation of the current time BPM is your pulse rate you took earlier Difficulty is simply taken from the constant at the top of our program. We won't use this field in this tutorial but it's useful to have if we're doing further verification and we want to make sure the difficulty is consistent with the hash results (i.e. the hash result has N prefixed zeros so Difficulty should also equal N, or the chain is compromised)
The for loop is the critical piece in this function. Let's walk through what's happening here:
We'll take the hex representation of i and set Nonce equal to it. We need a way to append a changing value to our hash that we create from our calculateHash function so if we don't get the leading number of zeros we want, we can try again with a new value. This changing value we add to our concatenated string in calculateHash is called a "Nonce" In our loop, we calculate the hash with i and Nonce starting at 0 and check if the result starts with the number of zeros as defined by our constant difficulty . If it doesn't, we invoke the next iteration of the loop with an incremented Nonce and try again. We added a 1 second sleeper to simulate taking some time to solve the Proof of Work We keep looping until we get the number of leading zeros we want, which means we've successfully completed our Proof of Work. Then and only then do we allow our Block to get added to blockchain via our handleWriteBlock handler.
We're done writing all our functions so let's complete our main function now:
With godotenv.Load() we load up our environment variable, which is just the :8080 port we'll access from our browser.
A go routine creates our genesis block since we need to supply our blockchain with a starting point.
We fire up our web server with our run() function we created earlier.

While GPU mining still does work better on AMD-based graphics processors using OpenCL, the latest versions of the CUDAminer software intended for use on Nvidia-based graphics cards has gone through a good performance optimization and it makes mining with CUDA a good option if you have some spare and unused Nvidia GPUs. The fact tha there are still shortages of the Radeon R9 280X graphics cards on the market - the all-round best performer for Scrypt GPU mining makes the alternative to mine coins with Nvidia GPU a decent alternative. Of course the price/performance ratio of an Nvidia GPU versus and AMD GPU for mining is still in favor of AMD graphics. You can expect to get about 550-560 KH/s from a stock (non overclocked) Nvidia GeForce GTX 780 Ti graphics card, while the same performance is easily achievable with a much cheaper stock AMD Radeon R9 280X card. If you however have a watercooled 780 Ti and overclock it well, you might be able to reach hashrate close to about 900 kHash/s according to the author of the software. Regardless, if you already have a CUDA-capable graphics processor why not put it to some mining work to get some extra crypto coins, it also makes for a good option to try out new pools or alternative cryptos...
One of the best things about the CUDAminer software is that it automatically detects the best settings for your graphics card, so that after yo run it the software can squeeze out the maximum mining performance automatically for you. This takes the guesswork and a lot of time spent for testing different settings, though you can still do that if you wish to fine tune things. One of the still missing important features from this miner is the failover pool switching to backup pools in case of a problem with the current mining pool. CUDAminer already has support for scrypt mining with N=1024 (LiteCoin and many, many other scrypt clones like DOGE for example), scrypt-jane mining (Yacoin and several clones), scrypt mining with larger N (VertCoin) and the recently released MaxCoin mining (SHA-3 i.e. Keccak256). So you will be up to speed even with the latest alternative crypto currencies such as VertCoin and MaxCoin that have generated quite some buzz in the last few days. Below you can download the latest binary for windows of CudaMiner or you can compile it yourself from the (source).
Update: CudaMiner is now an old and non supported anymore miner for Nvidia GPUs, you should switch to the more recent and supported ccMiner instead in order to get better support, including for newer mining algorithms and coins, as well as faster hashrates for your Nvidia-based GPU mining rigs!

MacAfee blocked download of cuda miner because it contains a virus or spyware.
It is a common problem, most antivirus software detects and reports many of the software miners based on cpuminer, cgminer etc. as possible viruses. If you wish you could just compile the miners from source, but you'd still get the same warnings. If you don't know how to compile it, we have published a guide for that as well.

This means making use of all the spare computing in the world for cloud computing making computing more cost effective and greener than it it today. Stage one was creating a more profitable and easier to use mining software for both beginner and advanced mining enthusiasts. Step 2 was to use this platform and technology to distribute out cloud computing providing 10x savings in costs of cloud computing and at least 3x increase in earnings for miners and end users. We believe that crypto will change the world but the first step is to provide the tools and platform to make this incredible technology accessible to a larger audience.

Bitcoin mining Software for Ubuntu.
As you probably already know, we try to find and feature the best Bitcoin mining software for all operating systems, and Linux mining software is no exception. In this article, I'll show you how to setup the Bitcoin mining software for Ubuntu.
Right now, we have 2 Linux mining apps featured on our website- Cudo Miner and MinerGate. I personally tested both of them on Windows, but never on Linux- until now.
For this test I am going to use my laptop, as well the latest version of Ubuntu installed with Wubi.
The laptop specs are as follows:
i7-2630QM CPU @ 2.00 GHz 8GB DDR3 RAM nVidia GeForce GT 525M.
and the Ubuntu version is 18.10.
Now, if you know a bit about mining hardware, you know that this is not a suitable machine for Bitcoin mining- it has an old mobile processor with an old mobile graphic card. Still, it can run most operating systems out there, and it is more than good for everyday use, so it will suffice for our purpose- to try and install the Bitcoin mining software for the Linux/Debian operating systems.
How to mine Bitcoin on Ubuntu with Cudo Miner.
So the first thing to do is to go to our Cudo Miner page, click the big blue button and download Cudo Miner for Ubuntu.
Depending on your settings, you may have to thick a few check-boxes under Apps -> Software & Updates:
Be sure to have them the same as on the screenshot above. We didn't do it at first, and we couldn't install neither Cudo Miner nor MinerGate on Ubuntu 18.10.
So you install the Cudo Miner in a few basic steps, run it via Apps - Cudo Miner and the GUI miner for Ubuntu starts:
Tweak the settings according to your preference and hit "Save".
If everything is good, the Cudo Miner should spend additional minute or so at benchmark and file downloads, after which it should start mining automatically:
But it worked for the CPU only, which started working immediately, while GPU mining was showing an empty box.
We tried updating the whole system by going to Apps -> Software Updater:
but that didn't help much:
So I opened Apps -> Terminal and run:
then went back to Apps -> Software & Updates and clicked on the Additional Drivers tab .
In my case, the GPU was using an unofficial/open source driver, so I've changed it to the proprietary/tested driver from nVidia and applied the change:
This didn't help either. So I did a bit more research and somehow realized that I probably need to have the Cuda drivers installed, as they are pretty much essential for Bitcoin mining with nVidia GPUs.
Opened the Apps -> Terminal again, and then run the following:
sudo add-apt-repository ppa:graphics-drivers/ppa.
sudo apt update.
sudo ubuntu-drivers autoinstall.
and after the PC rebooted:
sudo apt install nvidia-cuda-toolkit gcc-6.
which took quite some time...
but it finally worked! The Cuda drivers made all the difference and I was able to start mining with my GPU as well.
Conclusion for Cudo Miner on Ubuntu.
I'm a below average user of Ubuntu who used it once per year on average for the last 15 years. Yet, I've pulled this pretty easily since this is really basic stuff for Ubuntu users. All in all, I can just say- a GUI Bitcoin miner for Linux definitely exists, it's really easy to setup and most importantly- works.
And even if you never used Ubuntu- you should definitely try it. As mentioned before, this laptop is really old when it comes to Bitcoin mining, and if you have a more recent hardware or an AMD GPU this should work much easier for you.
And now that we have an up to date Ubuntu 18.10 with the latest Cuda drivers up and running- let's see how fast we can start mining Bitcoin with MinerGate:
How to mine Bitcoin on Ubuntu with MinerGate.
First things first, get the installation files by clicking the big blue button on this page, and then install the .deb package as you would install the Cudo Miner or any other app.
Few seconds and 2-3 button clicks later, you run it from Apps -> Miner Gate , choose extended mode, sign in and can start mining:
And while it started mining with CPU almost instantly, the GPU mining complained about low memory and wouldn't start for any of the coins listed.
Since my Ubuntu 18.10 is up to date with all requirements, including the latest Cuda drivers- I didn't go further. Still, the installation and mining with CPU was really effortless, so I believe that those with newer graphic cards won't have any issues with GPU mining and MinerGate on Ubuntu.
Update: I've just made a video where I show you how you can install and setup the Bitcoin mining software for Ubuntu:
