Now that we have our artifacts, click on the Ethereum logo under the Solidity icon, select your contract in the dropdown menu, and click on deploy:. When deployed, our smart contract should have issued tokens to our wallet! Clicking on the dropdown menu will give you access to all of the ERC20 methods, that your contract has inherited or implemented:.

The total supply of the token is issued on deployment and sent to the deploying wallet address. In this case, the total max supply is regulated through economic-driven principles and not on a hard-coded value. Think of a Miner validating a transaction and getting tokens back as a reward, or a user stacking their tokens to receive periodic rewards.

The absence of a hardcoded Max supply, though, could make your token inflationary , incurring a loss of value over time, or worst putting its security at risk. Even if this goes outside the focus of this tutorial, is good to understand that we can, and should, cap our supply. Like in the Uncapped Lazy Supply mechanism, the tokens are issued in small quantities , with the only difference that here the max-supply is decided beforehand and hardcoded in the smart contract, or passed on deployment.

We can check the token balance of the address that deployed the token by calling the balanceOf method, just like we did before. To achieve this we can simply move the mint function from our constructor to a new public function that can be called under different circumstances:. In this case, every time issueToken is called, the caller will receive that amount of tokens.

Of course, we can also pass arguments to vary the issued amount of coins or the receiver:. As a workaround, we can cap the total supply of the Token. This allows us to substitute the ERC Now that we have a mintable Token there is one issue left to solve: everyone can mint it by calling the issueToken function, and that rises a huge security issue. Gladly, there is a solution to it: Owned contracts.

Copying what the OpenZeppelin documentation on access-control tells us:. The access control of your contract may govern who can mint tokens, vote on proposals, freeze transfers, and many other things. It is therefore critical to understand how you implement it, lest someone else steals your whole system. This approach is perfectly reasonable for contracts that have a single administrative user.

As we can notice, the Token contract is now inheriting both from the ERC20, and Ownable contract, this gives us access to the onlyOwner function modifier applied to the issueToken function. By default, the owner of an Ownable contract is the account that deployed it, which is usually exactly what you want. Navigate to the project folder, install Hardhat and the dependencies needed to compile and test our Token smart contract:.

This will populate our project directory with the default Hardhat files and folders. The next step will be to modify the hardhat. Navigate to alchemy. Open the hardhat. The next step is to add the private key of the wallet we want to use the deploy the Token on the blockchain, but first, we need to install the dotenv library to keep our private key secure. In the terminal, inside the project folder, install the dotenv library by typing:.

Once created, add the. Make sure to keep your secrets…secret. Go back to the. To do so, at the start of your hardhat. Now, inside the module. Our hardhat. We declare an async function and deploy the token passing as an argument the totalSupply value needed in the Token constructor. The only difference is that in digital networks this information will not be altered in any way. You have probably heard of BitTorrent, one of the most popular P2P file sharing content delivery systems.

Another popular application for P2P sharing is Skype, as well as other chat systems. To understand digital identities, we need to understand how cryptographic hashing works. Hashing is the process of mapping digital data of any arbitrary size to data of a fixed size. In simpler words, hashing is a process of taking some information that is readable and making something that makes no sense at all.

You can compare hashing to getting answers from politicians. Information you provide to them is clear and understandable, while the output they provide looks like random stream of words. If you take a look at the simple statistics, we will have a limited but huge number of possible HASH values, simply because our HASH length is limited. If you think Hamlet is just a name or a word, please stop reading now, or read about the Infinite Monkey Theorem.

When signing a paper, all you need to do is append your signature to the text of a document. A digital signature is similar: you just need to append your personal data to the document you are signing. If you understand that the hashing algorithm adheres to the rule where even the smallest change in input data must produce significant difference in output , then it is obvious that the HASH value created for the original document will be different from the HASH value created for the document with the appended signature.

A combination of the original document and the HASH value produced for the document with your personal data appended is a digitally signed document. And this is how we get to your virtual identity , which is defined as the data you appended to the document before you created that HASH value.

Next, you need to make sure that your signature cannot be copied, and no one can execute any transaction on your behalf. The best way to make sure that your signature is secured, is to keep it yourself, and provide a different method for someone else to validate the signed document.

Again, we can fall back on technology and algorithms that are readily available. What we need to use is public-key cryptography also known as asymmetric cryptography. To make this work, you need to create a private key and a public key.

These two keys will be in some kind of mathematical correlation and will depend on each other. The algorithm that you will use to make these keys will assure that each private key will have a different public key. As their names suggest, a private key is information that you will keep just for yourself, while a public key is information that you will share. If you use your private key your identity and original document as input values for the signing algorithm to create a HASH value, assuming you kept your key secret, you can be sure that no one else can produce the same HASH value for that document.

If anyone needs to validate your signature, he or she will use the original document, the HASH value you produced, and your public key as inputs for the signature verifying algorithm to verify that these values match. Assuming that you have implemented P2P communication, mechanisms for creating digital identities private and public keys , and provided ways for users to sign documents using their private keys, you are ready to start sending information to your peers.

Since we do not have a central authority that will validate how much money you have, the system will have to ask you about it every time, and then check if you lied or not. So, your transaction record might contain the following information:. The only thing left to do is digitally sign the transaction record with your private key and transmit the transaction record to your peers in the network.

Your job is done. However, your medication will not be paid for until the whole network agrees that you really did have coins, and therefore could execute this transaction. Only after your transaction is validated will your pharmacist get the funds and send you the medication. Miners are known to be very hard working people who are, in my opinion, heavily underpaid.

In the digital world of cryptocurrency, miners play a very similar role, except in this case, they do the computationally-intensive work instead of digging piles of dirt. Unlike real miners, some cryptocurrency miners earned a small fortune over the past five years, but many others lost a fortune on this risky endeavour.

Miners are the core component of the system and their main purpose is to confirm the validity of each and every transaction requested by users. In order to confirm the validity of your transaction or a combination of several transactions requested by a few other users , miners will do two things. They will look into the history of your transactions to verify that you actually had coins to begin with.

Once your account balance is confirmed, they will generate a specific HASH value. This hash value must have a specific format; it must start with certain number of zeros. Considering that even the smallest change in input data must produce a significant difference in output HASH value , miners have a very difficult task. They need to find a specific value for a proof-of-work variable that will produce a HASH beginning with zeros.

Once a miner finds the proper value for proof-of-work, he or she is entitled to a transaction fee the single coin you were willing to pay , which can be added as part of the validated transaction. Every validated transaction is transmitted to peers in the network and stored in a specific database format known as the Blockchain. But what happens if the number of miners goes up, and their hardware becomes much more efficient?

As the hash rate goes up, so does the mining difficulty, thus ensuring equilibrium. When more hashing power is introduced into the network, the difficulty goes up and vice versa; if many miners decide to pull the plug because their operation is no longer profitable, difficulty is readjusted to match the new hash rate.

The blockchain contains the history of all transactions performed in the system. Every validated transaction, or batch of transactions, becomes another ring in the chain. Every single blockchain development company relies on this public ledger. So, the Bitcoin blockchain is, essentially, a public ledger where transactions are listed in a chronological order.

There is no limit to how many miners may be active in your system. This means that it is possible for two or more miners to validate the same transaction. If this happens, the system will check the total effort each miner invested in validating the transaction by simply counting zeros. The miner that invested more effort found more leading zeros will prevail and his or her block will be accepted.

Today, those would be considered among the top tier geeks, just below the kinds of people that still fight over the merits of Vim versus emacs. Download the latest version of the Wallet. The first thing you have to do on it is create an ethereum account. Most of the contracts here will cost less than a tenth of a US penny. The wallet only allows basic mining on the testnet, but if you want to try your luck on the real net, then you need a more advanced tool.

This used to be a cumbersome process but now there are better easier tools: and we have new tools that will make that process much easier. The AlethOne miner is a straightforward tool with two buttons: press one to start mining in your GPU and press the other to deposit your rewards in a wallet. 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. Before we get into the steps above, let's cover some important terms you should know when getting started. Before we dive into the technicalities of how to create your own cryptocurrency, we should set our facts straight and take a look at some basic definitions used in all cryptocurrency-related conversations.

Now, a cryptocurrency can be defined as a digital currency relying on encryption to generate new units and confirm the transactions. It has all the functions of the currency with the difference of running outside of a single centralized platform such as a bank. So what exactly is the difference between them? Simply put, it all comes down to these three points:. Coins require their own blockchain while tokens can operate on the existing ones.

Tokens are limited to a specific project; coins can be used anywhere. If you want to put tokens and coins in a real-life context, think about tokens as your Frequent Flyer Miles while coins are actual money: you can use both to get an airplane ticket, but with the miles your choice will be limited to the air company that issued them, while with the money you can take your business anywhere you want. The bottomline is that you need to build a blockchain if you want to create a crypto coin.

One more word on blockchains here: many authoritative business analysts foresee a big future and a growing list of the markets and industries where the blockchain technology will significantly disrupt the status quo and generously reward the early adopters. The other important aspect is that when you decide to start a cryptocurrency you get a whole set of powerful marketing tools and consumer benefits which will help you differentiate yourself from the competition.

No more trade restrictions in any markets. Do your business interests lay in smart contracts area, data authentication and verification or in smart asset management? Define your objectives clearly at the very beginning. For your blockchain to operate smoothly the participating nodes must agree on which transactions should be considered legitimate and added to the block. Consensus mechanisms are the protocols that do just that. There are plenty to choose from for the best fit for your business objectives.

To give you a better idea of what is out there, here is a list of the most popular blockchain platforms:. If you imagine a blockchain as a wall, nodes are the bricks it consists of. A node is an Internet-connected device supporting a blockchain by performing various tasks, from storing the data to verifying and processing transactions. Blockchains depend on nodes for efficiency, support, and security. Tread carefully as some of the parameters can not be changed once the blockchain platform is already running.

Make sure to check whether the blockchain platform of your choice provides the pre-built APIs since not all of them do. Communication is the key and a well-thought-out interface ensures a smooth communication between your blockchain and its participants. Slowly but surely the law is catching up with the cryptocurrencies and you better protect yourself from any surprises by looking into the trends around the cryptocurrency regulations and the direction they are headed.

Get a headstart into the future and think how you can boost your blockchain by tapping into the future-proof technologies like the Internet of Things, Data Analytics, Artificial Intelligence, Cognitive service, Machine Learning, Containers, Biometrics, Cloud, Bots and other inspiring developments. As you can see, it takes a lot of time, resources, and particular skills to build a blockchain. Therefore, every time you want to change your blockchain parameters or introduce new features, you will need to create a fork.

Soft forks are less demanding. Simply a majority of the nodes is required to update the software and those who run a previous version can continue to operate. Now, the Bitcoin forks are the changes in the Bitcoin network protocol.
