Check our previous blog post describing in detail how to connect to a Substrate node and query it for some basic data. Here is a shortcut. First of all, we need to create a new NestJS project.

If you do not have the Nest CLI installed you can check the docs here or just install it with a following command:. For the lib to work correctly, add the following to your tsconfig. Add Polkadot api-contract library to interact with the Contracts Pallet. It is also possible that you will need another version of Node. You can use Node Version Manager to manage different versions. We will add a ContractService to interact with the smart contract. This service will implement the OnModuleInit interface.

In the onModuleInit function we will create the connections to the api. First of all we need to create a WebSocket Provider with the url of our node. As we are using a local node it simply is localhost. Next, we will create the ApiPromise object using the web socket provider. We need to declare a class scoped variable:. We will now create a PromiseContract object from the api-contract library. This object is tightly connected with the contract we have created so we need some more information about it.

We need the contract address. To get it, visit Polkadot JS Apps. Clicking on the image next to the contract name here it is ERC Copy the metadata. Add a property to your tsconfig. We can now query the node for the total supply of our token. We are going to use the call function from the PromiseContract class.

The call function creates a ContractCall , which exposes a send function:. We need to specify the account, which is going to call a function. To make things simple, we will use Alice predefined account:. In the code snippet below we call the totalSupply function which does not have any parameters so we can omit the params and send it as Alice. An important note on the gas limit value. When you were initializing the contract with Polkadot JS Apps, maximum gas limit of 1 was enough.

Here we pass six more zeros. Now we can create a controller to expose the function. In the src directory create a file balances. Set the controller route, inject ContractService and create a function totalSupply decorated with Get which calls the contractService. Each currency value is a decimal stored as an integer with a fixed and known number of decimal places in Substrate Node Template it is 15 by default.

Polkadot JS Apps wraps that for you in the input field, so that I have indeed initialized the contract with one million units. However, when querying the smart contract through the Polkadot JS Apps or using the api we always get the additional 15 decimal zeros. Another snippet shows how to call the balanceOf function. The only difference is that we need to pass the parameter to specify whose balance we are asking of. As we already know how to read data from our smart contract, it is time to make a transaction.

To sign a transaction alongside sending it, we need to pass a KeyringPair instead of the account's address. As we are in development mode, we will use the predefined Alice account again, so creating a KeyringPair is fairly simple:. There are two ways to call the transfer function. One would be to use the apiContract. As a result of this function, we get the extrinsic hash. It is not the block hash, because the transaction was yet only submitted to the transaction query.

The extrinsic hash alone is not unique over the chain, so we would prefer to know the block hash. Therefore we will use a function from the basic Polkadot api this time. A finalized transaction does not mean a successful transaction. It only means that the processing of a transaction has finished. We can check in Polkadot JS Apps if the transaction is successful.

On the right side, you can see the events emitted by the smart contract. The last one says ExtrinsicSuccess , so we know the transaction was successful. Once the transaction is finalized, view its details. You can see the ExtrinsicFailed event.

The chain is also secured with cryptography , and significantly, no one can change the chain after the fact. From a technical perspective, the blockchain utilizes consensus algorithms , and transactions are recorded in multiple nodes instead of on one server. A node is a computer connected to the blockchain network, which automatically downloads a copy of the blockchain upon joining the network.

For a transaction to be valid, all nodes need to be in agreement. Though blockchain technology was conceived as part of Bitcoin in , there may be many other applications. Technology consulting firm CB Insights has identified 27 ways it can fundamentally change processes as diverse as banking, cybersecurity, voting, and academics. The Swedish government, for example, is testing the use of blockchain technology to record land transactions , which are currently recorded on paper and transmitted through physical mail.

Effective mining requires both powerful hardware and software. To address this, miners often join pools to increase collective computing power, allocating miner profits to participants. Groups of miners compete to verify pending transactions and reap the profits, leveraging specialized hardware and cheap electricity. This competition helps to ensure the integrity of transactions. Cryptocurrency exchanges are websites where individuals can buy, sell, or exchange cryptocurrencies for other digital currency or traditional currency.

The exchanges can convert cryptocurrencies into major government-backed currencies, and can convert cryptocurrencies into other cryptocurrencies. Almost every exchange is subject to government anti-money laundering regulations, and customers are required to provide proof of identity when opening an account. Instead of exchanges, people sometimes use peer-to-peer transactions via sites like LocalBitcoins , which allow traders to avoid disclosing personal information.

In a peer-to-peer transaction, participants trade cryptocurrencies in transactions via software without the involvement of any other intermediary. Cryptocurrency wallets are necessary for users to send and receive digital currency and monitor their balance. Wallets can be either hardware or software, though hardware wallets are considered more secure.

While the transactions and balances for a bitcoin account is recorded on the blockchain itself, the private key used to sign new transactions is saved inside the Ledger wallet. When you try to create a new transaction, your computer asks the wallet to sign it and then broadcasts it to the blockchain. Since the private key never leaves the hardware wallet, your bitcoins are safe, even if your computer is hacked.

In contrast, a software wallet such as the Coinbase wallet is virtual. Coinbase introduced its Vault service to increase the security of its wallet. Released in by someone under the alias Satoshi Nakamoto, Bitcoin is the most well known of all cryptocurrencies. Despite the complicated technology behind it, payment via Bitcoin is simple. In a transaction, the buyer and seller utilize mobile wallets to send and receive payments.

The list of merchants accepting Bitcoin continues to expand, including merchants as diverse as Microsoft, Expedia, and Subway, the sandwich chain. Although Bitcoin is widely recognized as pioneering, it is not without limitations. For example, it can only process seven transactions a second. By contrast, Visa handles thousands of transactions per second. The time it takes to confirm transactions has also risen.

Not only is Bitcoin slower than some of its alternatives, but its functionality is also limited. Other currencies like Bitcoin include Litecoin , Zcash and Dash , which claim to provide greater anonymity. Ether and currencies based on the Ethereum blockchain have become increasingly popular. However, issues with Ethereum technology have since caused declines in value. Ethereum has seen its share of volatility. Put simply, smart contracts are computer programs that can automatically execute the terms of a contract.

With traditional operations, numerous contracts would be involved just to manufacture a single console, with each party retaining their own paper copies. However, combined with blockchain, smart contracts provide automated accountability. Smart contracts can be leveraged in a few ways: When a truck picks up the manufactured consoles from the factory, the shipping company scans the boxes. Beyond payments, a given worker in production could scan their ID card, which is then verified by third-party sources to ensure that they do not violate labor policies.

As mentioned previously, cryptocurrency has no intrinsic value—so why all the fuss? People invest in cryptocurrencies for a couple primary reasons. Apart from pure speculation, many invest in cryptocurrencies as a geopolitical hedge. During times of political uncertainty, the price of Bitcoin tends to increase. Bitcoin is not the only cryptocurrency with limits on issuance. The supply of Litecoin will be capped at 84 million units. The purpose of the limit is to provide increased transparency in the money supply, in contrast to government-backed currencies.

With the major currencies being created on open source codes, any given individual can determine the supply of the currency and make a judgment about its value accordingly. Applications of the Cryptocurrency. Cryptocurrencies require a use case to have any value. The same dynamic applies to cryptocurrencies. Bitcoin has value as a means of exchange; alternate cryptocurrencies can either improve on the Bitcoin model, or have another usage that creates value, such as Ether.

As uses for cryptocurrencies increase, corresponding demand and value also increase. Regulatory Changes. Because the regulation of cryptocurrencies has yet to be determined, value is strongly influenced by expectations of future regulation. In an extreme case, for example, the United States government could prohibit citizens from holding cryptocurrencies, much as the ownership of gold in the US was outlawed in the s.

Technology Changes. Unlike physical commodities, changes in technology affect cryptocurrency prices. July and August saw the price of Bitcoin negatively impacted by controversy about altering the underlying technology to improve transaction times. Conversely, news reports of hacking often lead to price decreases.

Still, given the volatility of this emerging phenomenon, there is a risk of a crash. Many experts have noted that in the event of a cryptocurrency market collapse, that retail investors would suffer the most. Initial coin offerings ICOs are the hot new phenomenon in the cryptocurrency investing space. ICOs help firms raise cash for the development of new blockchain and cryptocurrency technologies.

Startups are able to raise money without diluting from private investors or venture capitalists. Bankers are increasingly abandoning their lucrative positions for their slice of the ICO pie. Not convinced of the craze? With cryptocurrencies still in the early innings, there are many issues surrounding its development. According to this theory, members of society implicitly agree to cede some of their freedoms to the government in exchange for order, stability, and the protection of their other rights.

By creating a decentralized form of wealth, cryptocurrencies are governed by code alone. The following section will discuss these tangible aspects of cryptocurrency development. Under current accounting guidelines, cryptocurrencies are most likely not cash or cash equivalents since they lack the liquidity of cash and the stable value of cash equivalents.

In the US, IRS Revenue Ruling stated that holders of cryptocurrencies should account for them as personal property, with gains or losses on purchases or sales. The value of cryptocurrency holdings on balance sheets would be at cost or fair market value at the time of receipt. The ruling left many questions unanswered. These rules exclude certain investment assets, but do not explicitly exclude cryptocurrencies, so their applicability is unclear.

Outside the US, accounting treatment of cryptocurrencies varies. In the EU, a decision of the European Court of Justice rules that cryptocurrencies should be treated like government-backed currencies, and that holders should not be taxed on purchases or sales. Regulatory treatment of cryptocurrencies continues to evolve, but because the technology transcends global boundaries, the influence of national regulators is limited. Japan has not only legally recognized Bitcoin, but also created a regulatory framework to help the industry flourish.

This is considered a major step forward for legitimizing cryptocurrencies. The media has generally praised the new regulatory scheme, though the Japanese Bitcoin community has criticized the system as hampering innovation. The move follows the major fraud and investor losses from the Mt. Gox Bitcoin exchange scandal. The retail investor— Mrs. She wants something regulated and trustworthy. On the other hand, US regulators have been less than keen about the rise of virtual currencies.

US regulators are starting to crack down on previously unregulated cryptocurrency activities. Take initial coin offerings ICOs for example. Despite their popularity, many ICOs are for new cryptocurrencies with speculative business models, and have been widely criticized as scams. Since ICOs can be sold across national borders, it remains to be seen whether ICO issuers will choose to comply or simply move transactions outside of the US.

Due to the pseudonymous nature of ICO transactions, it may be difficult for national governments to significantly limit cryptocurrency sales or trading. Next, you could consider an audit of your project and a final legal check. While pretty much anyone can create a cryptocurrency, developing a solid project requires serious work and dedication.

The idea of creating your own cryptocurrency, use cases, and audience is an exciting one for many crypto fans. But where is the best place to start? There are actually many ways to create coins and tokens. The costs and knowledge also vary based on the complexity of your project. If you're thinking about creating your own cryptocurrency, our article lays out the very basics for you to get started. Fairly simple to create with pre-existing tools and open-source code.

Creating a token on an existing blockchain can leverage its reputation and security. While you won't have complete control over all aspects of your token, there is still a lot of customization available. There are a variety of websites and tools available to create your own token, especially on BSC and Ethereum. If you're looking to push the limits of what a coin or blockchain does, creating a coin with its own blockchain would likely be better.

Creating a new blockchain and coin is certainly harder than issuing a crypto token. But if done right, it can bring lots of innovation and new possibilities. Still, both options will require a lot of hard work along with technical, economic, and market knowledge to succeed.

Apart from the obvious choices like your blockchain or creating a coin or token, there are a few other key areas to consider:. Countries around the world have their own laws and rules regarding cryptocurrencies. Some jurisdictions may even ban the use of cryptocurrencies.

Consider fully your legal obligations and any compliance issues you might face. If you're only creating a token, not every step in the tutorial below will apply. What's more important would be the three design steps above. Most of our instructions will cover the basics of creating a blockchain first before finally minting your coin.

For a token, you'll need to pick the blockchain to mint your crypto on. BSC and Etheruem are popular options, but sidechains can also be a good idea. To create your own coin, you'll need to think about designing or hiring someone to create a custom blockchain.

Unless you have expert development knowledge, you'll need external help to build your ideas. Once the blockchain runs in a live environment, it's extremely difficult to change its core concepts and rules. Make use of a testnet to ensure that everything works as planned and ideally cooperate with a whole development team to build your blockchain.

Auditing companies like Certik can check the code of your blockchain and its cryptocurrency to look for any vulnerabilities. You can then publish the audit publicly and also act on its findings. This process provides some safety assurance for you as the creator and for any potential users or investors. Now that you have your blockchain running and are ready to mint your cryptocurrency, it's best to ask for expert legal advice to check whether you will need to apply for permission. Again, this step is difficult to achieve alone and requires outside help.

Whether you're creating a token or coin, you will need to mint the cryptocurrency at some point. The exact method will differ based on your tokenomics. For example, fixed supply tokens are usually minted all in one go via a smart contract.

Coins like Bitcoin are minted gradually, as miners validate new blocks of transactions. The costs involved are linked to the methods and setup you choose. If you're creating a coin and blockchain you'll likely have to pay a whole team over multiple months. When we average this out, to create a cryptocurrency with some chance of success, you'll likely need to spend thousands of dollars on its creation, marketing, and community building.

If you decide to make your own cryptocurrency, make sure to use our information only as a starting point. It's a deep topic that takes a long time to understand fully. Beyond creating the token or coin, you also need to think about making it a success post-launch. How to Create Your Own Cryptocurrency? Table of Contents. Tech Blockchain Tutorials. A cryptocurrency , also known as crypto, is a type of digital asset with multiple use cases. It's primarily a way to transfer value between people digitally, including monetary value, ownership rights, or even voting privileges.

Crypto differs from other digital payment systems because of its roots in blockchain technology. This basis gives cryptocurrencies more freedom from central entities like governments or banks. Bitcoin is the most famous example of a cryptocurrency. It has a simple use case of transferring monetary value to anyone across the globe without the need for intermediaries.

Its blockchain records all transactions and ensures security and network stability. Cryptocurrencies can roughly be split into two categories: coins and tokens. The difference between them is simple. Coins have their own native blockchain, like Bitcoin, for example. Ether ETH has the Ethereum blockchain. Coins typically have a specific utility over the whole network, like paying for transaction fees , staking , or taking part in governance.

Tokens are built on pre-existing blockchains. They might have some similar roles to coins, but tokens mainly have utility in their own projects. You can also use it to pay for certain transactions in the PancakeSwap ecosystem, like minting Non-Fungible Tokens or playing their lottery. The same is true for the thousands of ERC tokens issued on the Ethereum blockchain.

Each token is part of a specific project with different use cases. As mentioned, creating a token is much simpler than creating a coin. A coin requires you to develop and successfully maintain a blockchain. You could fork create a copy another existing chain, but this doesn't solve the problem of finding users and validators to help your network survive. Nevertheless, the potential for success with a new coin can be higher than just making a token.

Here's a basic overview of the two options:. Coin Token Runs on its own blockchain network Can be built on existing blockchains with an established user base Requires advanced blockchain knowledge and coding skills Fairly simple to create with pre-existing tools and open-source code Blockchain development is more costly and takes time Token development is faster, simpler, and relatively cheap. Creating a new coin can take a lot of time if you develop your own blockchain.
