First of all, you need to decide on whether to create a coin or a token. While a coin has its own blockchain, a token runs on a platform upon which it is tailored to run. A coin runs on its own proprietary and independent blockchain. So, to make a coin, you will have to build your own blockchain from scratch.

Creating an entirely new blockchain requires experience and understanding in coding, blockchain technology, and encryption. This option is not suitable for new developers, as many errors can occur, and it will require a lot of time, even for experienced programmers. A simpler option to create your own cryptocurrency is to fork from the code of an existing coin.

You just copy the code of Bitcoin or another chain, add a new variable, modify some values, and you will have your own blockchain. Many top coins have come into existence by forking from Bitcoin, such as Bitcoin Cash, Litecoin, Zcash, etc. Another easier way to create your own cryptocurrency is to use the services of platforms that give you the tools to launch your own token.

This option is more feasible for those who are looking to quickly launch a crypto, as it requires less development time, spending, and maintenance. When you build a token on top of an existing blockchain, such as Ethereum, your token uses the secure network, decentralized architecture, and implemented consensus mechanisms of the blockchain. Tokens function similarly to smart contracts and can be programmed to represent various items or have different digital services. Tokens are usually launched in ICOs of Security token offering STO to help projects and startups get the funds they require for their operations.

In the following paragraphs, we will show you how to create a proper cryptocurrency. Read and follow each step very carefully in order to succeed. If you want to know how to create your own cryptocurrency, a good start is that you can choose from various Open Source Blockchains.

It is more recommended you use open-source technology to create your own blockchain, as developing a block-chain from scratch takes a great deal of time and money. Access your server using SSH via putty as administrator root access to install the blockchain directly on a live server. Run the following commands one by one we will be using Multichain in our example. Before you learn how to create your own cryptocurrency, you will have to make some adjustments according to what you need in your chain to create your own cryptocurrency, as blockchain cannot be changed after they get started.

Access your server as root administrator and run the following commands to start your blockchain:. Consensus mechanisms, or mining protocols, represent the code that handles how new tokens are issued and verifies the validity of transactions before adding them to the block. The most popular consensus protocols are PoW, PoS, but of course, there are many others you can look into.

By far the most popular is the Ethereum blockchain, with the ERC standard having been used for most of the tokens issued so far. We will use Ethereum as an example of a platform to create a token. You will need the Ethereum wallet app. Click on it, and the Solidity Contract Source Code field will pop up. You need to find and replace all occurrences with each one of them. This is very easy to do in any code editor.

Next, we need to specify the total supply and the decimals, which go hand by hand. You may be wondering why. Then our variables would be replaced as follows:. However if we want to have some decimals, say, 2 decimals, then we would need to modify the total supply, by adding a zero for each decimal at the end of the desired number.

Awesome, we are almost there. We now only need to specify the account which will receive all the tokens that get created. Head to MetaMask and copy your account number, and once more, find and replace the variable in all occurrences. At the end your code should look like this:.

Our file is now ready for deployment, that easy! The good people from Ethereum provide us with an IDE integrated development environment that is fully capable of handling the full process, from editing the files, building, and deploying, among many other things. The first section we see on the left is our contextual menu, and in the right section we see the welcome screen. As we are by default on the file explorer the contextual menu shows all the files and folders that are available.

There are already a few files in there now, but you can ignore them. Once the file is created simply past the code that we worked on your text editor. It should more or less look like this:. Our code is now ready to be compiled. For that, look at the icon bar on the left of the corner. The moment you do that, MetaMask will prompt you to confirm that you want to connect your MetaMask wallet to Remix, hit confirm.

The deployment process may take anywhere from a few minutes to up to who knows how many minutes depending on the status of the network at that time. Usually, I found that Ropsten will take 2 to 3 minutes, and the maximum wait time I had was 10 minutes. After the process is complete you will receive a confirmation on the screen with the information of your deployed contract, including the address where the code got saved. Up to this point, our token already exists in the Ethereum network and can be used to transact, however, how do you access your tokens?

Turns out that MetaMask as well as other walltes can already operate with your token as it follows a specification called ERC However wallets are not yet aware of the existence of your token, so you will have to manually add them.

One important data on that screen is the address where the code got deploy, please copy that using the copy icon on the right, highlighted in the picture above. This will automatically populate the token symbol and decimals fields. You can now see your tokens on your MetaMask wallet.

Today we learned how to build and deploy your own cryptocurrency by following the ERC20 interface and utilizing Remix and MetaMask.

You can have a friend sent to you or you can exchange it for bitcoins on a cryptoexchange. If you are a bitcoin fan we suggest you keep on eye on the btcrelay project, a fraud-proof sidechain that will launch soon and allow quick exchanges between ether and bitcoin without a third party. The first contract we are going to create is a token. Tokens in the ethereum ecosystem can represent any fungible tradable good: coins, loyalty points, gold certificates, IOUs, in game items, etc.

Since all tokens implement some basic features in a standard way, this also means that your token will be instantly compatible with the ethereum wallet and any other client or contract that uses the same standards. Your app should be looking like this:. If you send it to a friend, they will not see anything in their wallet yet. This is because the wallet only tracks tokens it knows about, and you have to add these manually.

A popup will appear and you only need to paste the contract address. And now you have your own crypto token! Next, we need to specify the total supply and the decimals, which go hand by hand. You may be wondering why. Then our variables would be replaced as follows:. However if we want to have some decimals, say, 2 decimals, then we would need to modify the total supply, by adding a zero for each decimal at the end of the desired number.

The process is super easy, and the code we provided though working is just a minimal example. You can build many great things on top of what we did today, and I hope I can hear from you all the great projects that you build using the power of blockchain.
