Create Your Own Cryptocurrency: Step-by-Step Guide

All you need to know if you consider the development of your own cryptocurrency

Blockchain, cryptocurrency, and dApps have gained in prominence. Starting from a number of popular cryptocurrencies such as Bitcoin and Ethereum ending with blockchain-based startups which sells ice cream – thousands of businesses consider the benefits of using crypto technologies. Let alone millions of people who are ready to invest in it.

There are multiple articles praising blockchain development advantages, but it’s hard to find consistent information revealing how to create a cryptocurrency.

This article focuses on planning the development process as well as demonstrates how to make right decisions before the project is started.

Analysis

As well as in any other major project development the first step in cryptocurrency development is Business Analysis. Its main goal is to figure out if the cryptocurrency or its initial idea is unique and realizable.

Currently, there are more than 1,500 cryptocurrencies. Creators of each one has implemented some form of new functions and features. In this, approximately 80% of such projects are based on Bitcoin, Ethereum or other cryptocurrency or constitute their forks*.

Fork is a use of software project code as a start for another one. In so doing, the core project can both continue or stop existing.

Fork is a use of software project code as a start for another one. In so doing, the core project can both continue or stop existing.

In the very beginning it is required to clearly articulate the unique features of cryptocurrency and check is there any other one with the same characteristics.

However, the development of unique features don’t guarantee cryptocurrency success and is not a signal for starting the development process. The viability of future cryptocurrency is defined by the interest it would generate to ordinary users. Impractical specificities won’t bring popularity to the project.

To catch the attention of users and persuade them to abolish the use of existing cryptocurrencies in favor of new one you need a non-standard algorithm, feature or functionality.

Consensus, in general, is interpreted as a process of decision making by a group of people. In this, there is no traditional vote. The decision is made if most participants have no objections. In Blockchain consensus is a set of mathematical rules and functions regulating work of the Network.

At this stage you should also think about the quantity of issued cryptocurrency and its business logic.

Thus, the first stage of work should aim to:

  • Identify the potential range of new cryptocurrency users – your target audience;
  • Specify the structure and amount of data used;
  • Create cryptocurrency business model;
  • Develop cryptocurrency pricing process.

Questions to ask yourself:

Is my cryptocurrency idea unique? How it differs from existing ones?Who is my target audience? Will this cryptocurrency be useful and practical? What issues is it going to solve? What will the pricing process be like? Will cryptocurrency issuing be limited?

Platform is a project foundation

Full and comprehensive business analysis helps to identify which development way is to choose. There are four basic options:

1. To fork Bitcoin or another cryptocurrency. In fact, the fork is a clone of the basic cryptocurrency with adding new functions or fixing bugs of previous version. Nowadays there are more than 50 Bitcoin forks. The most popular is Bitcoin Cash estimated at about $600.

2. The second option is to create a cryptocurrency based on so-called builder platform. The most popular solutions, in this case, are Ethereum, NEM and Stellar. The advantage here is relative simplicity of implementation and popularity of platform-fundament, which enhances the trust to project.

This option is a way to create not cryptocurrency, but a token. Tokens serve as units of calculation as well as company shares (security tokens) or, for example, digital obligations on feat goods and services (utilities tokens). When creating a token under a ready platform, client pays a commission and faces all its disadvantages or restrictions, as well as entirely depends on its current technical platform condition. One of the most well-known tokens issued on Ethereum is Tron.

3. Cryptocurrency development frameworks provide more freedom in idea implementation.

Framework is a set of ready-for-service modules simplifying the creating and support of technically complex or highload projects. The use of frameworks allows to build an absolutely custom project instead of coding from a scratch.

Exonum and Hyperledger Fabric can be identified as an example of such frameworks. By using it you can create your own cryptocurrency choosing and combining different offered modules. Framework provide best ready-to-use practices for free. It would be inevitable in case of creating a cryptocurrency under another platform. This, in turn, gives space for modification and customization for specific goals.

4. Finally, there is an option of blockchain and cryptocurrency development from scratch. However, it shouldn’t be considered as a commercial project because of high cost and long timeline.

In view of the foregoing, it appears the cryptocurrency development based on the existing platform presents its set of complexities (for example, fees) and it is difficult to customize for specific tasks. That is why it would be a good solution only for quite simple tasks. Fork leads to problems of initial cryptocurrency and requires work with big amount of hard-to-maintain code. You should also remember that other things being equal, a high-quality cryptocurrency fork with substantive changes in functional and consensus implemented, is more expensive than a completely new cryptocurrency development.

The most appropriate choice for a really new and unique cryptocurrency is a framework. It allows developing a system according to project requirements in quite short terms.

Questions to ask yourself:

Will my cryptocurrency be based on another one?
Are there enough resources to create a cryptocurrency from scratch?

Not a step without architecture

The next step after choosing basic system parameters is cryptocurrency architecture development.

It’s necessary to decide what consensus will be used, integrate it with business logic of project. It’s also needed to define if smart-contracts and multi user wallets will be implemented in your cryptocurrency. That is, you need to get answers for a number of specific issues, usually, the one who can answer them is a software architect. Laid architecture will determine future cryptocurrency productivity and scalability.

You should carefully consider the consensus issue. This is one of the crucial tasks in cryptocurrency development. And that is what defines transactions speed. Then, it is time to decide how to manage cryptocurrency wallets, what apps and technologies should be used.

You also need to choose if any commission will be withdrawn during the cryptocurrency transaction, charging rules which also influence architecture solutions. And finally, a cryptocurrency requires integration with external resources to ensure its resilience outside the platform (popular payment systems, other platforms, and apps).

You should remember that any changes in cryptocurrency architecture after the start of the development process would be quite expensive.

After future cryptocurrency analysis and architectural decision-making, it’s time to create project documentation and technical specification for the development. In fact, this documentation will represent Proof of Concept.

Questions to ask yourself:

Which consensus fits business logic of my cryptocurrency best?
Are smart contracts required for my cryptocurrency?
How will wallets be administered, through which apps and technologies? Are multisig wallets needed?
Is any commission will be withdrawn during the transaction? If yes, what will be the charging rules?
How will cryptocurrency be integrated with external resources?

Private or Public Blockchain?

The most popular cryptocurrencies are based on blockchain technology, though it is not the only option. For example, IOTA is based on unique Tangle technology.

There are two basic blockchain types: private and public.

cryptocurrency software developers

The main difference between public and private blockchain lies in the fact that the first one doesn’t belong to anyone. Public blockchain is controlled by the community which makes decisions on cryptocurrency further development path.

In private blockchain, one or several organizations have full control over all data centers and so make their decisions on strategic development or adding new functions.

The choice of blockchain type is defined by business requirements. If this is your first time of creating a cryptocurrency it’s better to choose a solution based on private blockchain. This option allows to change the concept of the cryptocurrency, update it and add new functions without hard forks.

Hard fork of public blockchain creates a risk of dividing users into two parts – nodes which continue to use the previous version and nodes updated to the new version. So in other words, you’ll have to create a “new blockchain” and persuade users to update in order to make changes.

If cryptocurrency is based on private blockchain you can change the type of consensus at any time. This, in turn, allows changing the type of blockchain to public one without any undesired effects. But this process itself is quite time-consuming. It is one of ways to create a cryptocurrency, test it on real users and make necessary changes as it is fully controlled by its creator(s).

Also, one of private blockchain advantages is that it allows high cryptocurrency transaction speed. Consensuses used in public blockchains (Proof-of-Work etc.) an order of magnitude less productive than for example Byzantium consensus which is used by Exonum.

Questions to ask yourself:

What transaction speed is required for my cryptocurrency?
Will cryptocurrency be changed or upgraded over time?
Based on business requirements, which type of blockchain will work best?

To mine, or not to mine: that is the question

Mining is directly related to consensus and type of blockchain. In most cases, if blockchain is public, the development task list contains the creation of software for mining. It is also necessary to implement mechanisms for miners to serve the network.

Most consensuses which imply mining are called Proof-of-Work which are rather slow. They will hardly fit a fast cryptocurrency. But yet they can recognize the cryptocurrency value through resources spent on mining.

Proof-of-Work is an algorithm for preventing distributed systems from malicious use. Its main points are:

the necessity of solving a quite difficult and long-term task and ability to check the result quickly and easily.

Mining actually defines the way of blocks and transactions confirmation, which ensures workability of cryptocurrency.

Questions to ask yourself:

Is mining feasible for my project?
What is more important for my cryptocurrency: transaction speed or data security?

New cryptocurrency in the real world

Any cryptocurrency has three main functions which are crediting funds, withdrawals, and transactions.

Cryptocurrency ecosystem aims to provide and simplify access to main functions from any device while providing stable reliability and security. It is needed to make cryptocurrency management available in desktop, web-application and mobile applications. Often these are separate processes which require several interfaces development and design for each version.

What cryptocurrency ecosystem includes?

Ready design and interfaces subsequently are applied to software template. As a result we get main elements of ecosystem.

Usually, ecosystem includes:

  • Wallets: web, mobile and desktop applications compatible with main operating systems.
  • Oracles, which are proxy servers playing a role of accurate data sources outside the system for smart-contracts implementing. They are required for blockchain-based systems to make contact with the outside world.
  • Third-party components, which are usually related to banks and exchanges where cryptocurrency converses into other ones of fiat assets.

Every above-mentioned element should include functions and modules required for minimal use cases.

  1. The list of such functions is the following:
  2. New user registration;
  3. Making purchases or withdrawal of coins;
  4. Administrator’s ability to manage the application;
  5. Transactions implementing;
  6. Gathering statistics about system’s work. Then it is used by admins and partially introduced to users;
  7. Processing of big amount of traffic;
  8. Receiving notifications on mobile devices;
  9. Interface localization for users from different countries and regions.

MVP or a working prototype

After making decisions on cryptocurrency architecture and implementation of main cryptocurrency functions, it’s time to start creating project’s MVP.

MVP (minimum viable product) is a working prototype. It allows to demonstrate concept feasibility as well as find problems and bottlenecks you could have faced if you started developing the full-fledged project primarily.

Establishing an MVP includes the development of core system, checking of main functions and concepts, fixing bugs. This is an optimal approach as blockchain is a quite young technology which has not yet formed best practices. That is why unexpected problems happen often during the implementation of non-standard projects.

Sometimes, you would need to set aside initial solutions and start the cryptocurrency development from the scratch because of wrong preliminary analysis. So it is recommended to begin with primitive MVP development. This allows to save time and resources for solving problems you could have avoided by bringing minor changes in architecture.

Depending on cryptocurrency business model and the objective, MVP focuses on different aspects. If the task is ICO and attracting investors – it emphasizes on its appearance and demonstrates innovation and value of project.

ICO (Initial Coin Offering) – during ICO the team sells digital tokens for cryptocurrency or feat money. Later this tokens can be used on the project platform as domestic currency or traded on stock exchanges.

If MVP is the first stage of creating the business and gathering the community around cryptocurrency, than primarily it is needed to implement necessary functions.

Stepping onto the stage

What is the best way to launch a cryptocurrency? It also depends on blockchain type.

In case of public blockchain, the determined deployment of network nodes on your own servers is not needed. Open-source code of public blockchain is placed to repository. Here one can download a ready-to-use binary code or compile it by himself. To launch the blockchain network several users need to download and run a couple of nodes among themselves. Indeed after that the cryptocurrency can be considered as a functioning one. New user which downloads next node and start mining becomes apart of the system and supports it.

ICO (Node is any computer connected to blockchain network. Nodes of decentralized system contact each other through P2P protocols for sharing data on blocks and transactions. Depending on its type, node stores all blockchain data or just a part of it.

If blockchain is private, it is deployed on servers. Servers are responsible for performance of core and third-party components. They are called cryptocurrency nodes. After configuration they start to participate in consensus and sign blocks.

Nodes are deployed on one or several data centers (e.g. Google data centers situated in different countries for ensuring greater systems’ reliability). The team of developers sets up and configures all necessary software and checks its workability.

Also in case of private blockchain you can create a repository where anyone can download a node storing the blockchain copy, but not having the right to sign blocks.

Vendor selection: eat a peck of salt together

One of the most important steps toward cryptocurrency creating is to choose a team of cryptocurrency software developers and planning of necessary resources. Often one needs to hire his own staff of developers. But it leads to a list of organizational matters. Moreover, in some cases, one has to pay developers a profit share of the project. To avoid these problems it’s better to consider cooperation with cryptocurrency development company.

It is a difficult task as there are fewer cryptocurrency developers on the market than it is needed and their services are quite expensive. Due to the high popularity of this field, there are a lot of unfair companies which aim to make money off clients who trusted them a project. Most of such pseudo-developers may not even know how to develop a new cryptocurrency. At best, they are able to program smart contracts on Ethereum and don’t understand the peculiarities of any consensus.

In most cases, by choosing a contractor a client concludes a “lifetime” agreement for its support as in future it will be easier, cheaper and more reliable.

When you as a client choose a vendor you should pay attention to who you are going to hire. As there is a risk to trust your project to people who have a lack of coding culture. The programme of such companies won’t be supported by other cryptocurrency developers.

But even if the cryptocurrency code and comments to it are high-quality it’s hard and expensive to change the cryptocurrency development company. It happens because of a number of reasons:

  • But even if the code and comments to it are high-quality it’s hard and expensive to change the development company. It happens because of a number of reasons:
    A project has been already deployed on servers configured by the first contractor. It means the project needs to be deployed again on new servers. There is an option to get the access to the initial servers, but you will still need to spend time in order to get into details of system configurations.
  • Off-site developers in most cases can’t make sense out of code. As even full documentation and comments don’t always allow to understand quickly how a big project works. Moreover, often company saves time on documentation to accelerate the development of functions.
  • New developers need time to understand thoroughly how the project works. Otherwise, they can make code ineffective and unsupportable.
  • A project could be built in rare and expensive language.

In addition, don’t forget to discuss, on which conditions contractor will support the project after launch.

In conclusion

To sum up, here is how the project of establishing new cryptocurrency looks like:

how to create a cryptocurrency

Processes described in this article might seem shocking and discouraging for a reader. But don’t jump into conclusions.

If you have an idea of new cryptocurrency and you are sure about its value, you need to find a team development experts. A team will be able to manage the whole task list starting from analysis and ending with project launch.

If it is a team of professionals who know how to implement your idea there won’t be any problem.
