How to Hire Blockchain Developers: A Comprehensive Guide

Did you know the global blockchain market is forecasted to become worth $1,431.54 billion by 2030 with a CAGR of 85.9% from 2022-2030? 

Blockchain is no longer a new technology; it has become the pillar for the web 3.0 revolution, and companies are heavily investing in it. Known as one of the most secure platforms for completing transactions, blockchain is already being used by 2.8% of the world’s population. Nevertheless, its neoteric stage leaves much of its potential untapped. What more? Many decision-makers, in both startups and time-tested establishments, still know just a little about the technology. This makes it difficult for them to invest in it to build more robust and reliable solutions for their business workflows. 

In this blog, we’ll uncover every aspect of investing in a blockchain development project by hiring a developer or a complete team. 

What is Blockchain Technology? 

Blockchain is a distributed ledger that stores information across multiple servers through a consensus-based authentication channel. There are two types of blockchains- public and private. Both of them differ in ways on account of how and who can access the blockchain. A private blockchain offers access only to the authorized users, while the public one is more open.  

Apart from this one difference, both the technologies are equally efficient and secure, since they both eliminate intermediaries and are immutable. The cryptographic hashing process makes blockchain immutable. While the consensus-based validations from all the parties concerned make it efficient. As such the technology is more transparent and efficient than any traditional data storage and transactional processing technology. 

Different Types of Blockchain Technology 

As discussed above, blockchain is primarily of two kinds, public and private. However,  

Before you  hire blockchain developer, you first need to know what type of blockchain technology is most suitable for your business goals. There are four main types of blockchain technology: 

Public blockchain 

A public blockchain is the most common form of blockchain and its most popular use case is cryptocurrency. Since, cryptocurrencies are made to be traded and used by the public at large, most of the cryptocurrencies including Bitcoin and NFTs are developed and traded through a public blockchain. Public blockchains are, in the true sense of the word, completely decentralized. They are non-restrictive and anyone with a stable internet connection can join it to process a transaction.

Private blockchain 

Private blockchains are a more restrictive form of public blockchains. As such it performs at a much smaller scale and is most appropriate for organization-based applications. Such blockchains function in closed networks and require additional authorization access, otherwise known as the private key to perform any transaction. 

Hybrid blockchain 

As the name suggests, hybrid blockchains are the combination of both private and public blockchains. These are designed to have more control over the network, while maintaining maximum decentralization and transparency. Organizations that are looking to segregate the information based on their confidentiality invest in such blockchains. This allows them to keep all their information publicly accessible, save some that they protect through private keys.

Consortium  

Consortium blockchains are yet another subtype of blockchains that are composed of present nodes and have access controls. They have fewer nodes//servers than public blockchain and hence are more secure. The fewer nodes mean the network consumes relatively less resources, and the lack of complete public access means less transparency. These blockchains are created with the objective of attaining greater speed in transactions. Since, consortiums do not have complete decentralization, they provide more control to the limited few nodes that actually are a part of it.

How to hire a Developer for Custom Blockchain Development Services?

Now, based on use cases and business objectives, any of the above mentioned blockchains can be developed. However, since they differ from each other to varying degrees, one developer, who has excellent experience in developing applications on public blockchains may not have an easy time developing one on consortium. That being said, the approach to hire a reliable blockchain developer doesn’t change much in itself, and here’s how you can follow it.

Define your developer needs

Definitely the foremost step in hiring someone for blockchain app development services is to know your requirements in complete details. You must know the type of developer you’re looking for your project. Whether it is a core blockchain developer you require, who can create a new blockchain for your organization from scratch, or just someone to develop an app on an already existing blockchain.

To understand fully, what kind of blockchain developer would be a best fit for your requirement, you must discuss the details with the IT leader of your firm. In case that cannot be done, you can ask a subject matter expert instead. Many companies offer free consultation for blockchain development services, since the technology is relatively new and many investors do struggle in defining their requirements in technical terms.

Create the job description 

Once you have a clearer understanding of your requirements from blockchain developers, you should work on listing your expectations from them. You should describe in complete detail the job description and requirements of the project to attract the right candidate.

While describing the job details, also ensure and mention whether you’re looking for the blockchain developer to work with your organization for long-term and on various projects, or someone for a one-time project. This will help both you and the candidates in setting the mutual expectations about the remuneration and time commitments.

Plan Your Hiring Strategy 

Some blockchain projects are gigantic and require a whole team of blockchain developers alongside professionals from domains like quality assurance, project management, DevOps, and more. While others may get completed by just one individual developer. This is why before posting your job opening on any platform, it’s important to agree on one hiring strategy.

Individual Developers

Some projects only need skills and efforts of one or two individual developers. In such a case, you can go ahead with hiring individual developers from companies or even from freelancing platforms. You can find and hire such individual developers from platforms like stack exchange and LinkedIn. However, managing each such resource can become a task in itself. This is why, hiring individual talents from companies can be a better idea for you, if productivity and hassle-free development cycle is your goal.

Full Time In-house Staff 

If your project is big and requires the efforts of many developers, hiring a full-time staff would be a good idea. Individual developers, in such cases, can become more of a hassle. Besides, it would be difficult for them to coordinate as much as such big projects require.A complete team hired in-house will not only help you develop projects dedicatedly with complete customization, but in the long run, it will help you develop more projects with a dedicated team of experienced developers. The only con of this approach is that if you don’t have consistent blockchain projects the team would become financial overhead for your organization.

Outsourcing the Project

The project-based option is ideal for companies who are looking to develop one project in the most cost-effective way. It is also a good option for companies looking to run a startup based on blockchain product. Such organizations usually can function easily with just staff from business background and other skills. They may not need development skills post-production and thus hiring an entire team for one-time job is not a great idea. The company may need some assistance from a professional with development skill, but one individual developer will not be enough for the development of entire project. This is why hiring a blockchain development company is the best option in such scenarios.

Vet the skillset of the developer 

Whether you hire an individual developer, a team, or a complete company for blockchain app development services, an inevitable part of the process is vetting the skills of the developers. You need to ensure that the developers understand programming concepts and has impeccable skills in languages like C, C++, Python, JavaScript, Solidity, and Go. A more detailed explanation of all the skills required is given below-

OOPS 

OOPS or Object-Oriented Programming Structure is the paradigm of the most popular programming languages of the day. A developer with instinctive understanding of the OOPS concepts will be able to learn and use many languages to create blockchain applications. They will know how to use classes, objects, encapsulation of functions, and more such concepts to create scalable programs.

Data Structures 

Other than the concepts of OOP, the developer will also need to have an extensive knowledge of data structures. A data structure is nothing but a special format for storing, organizing, retrieving, and processing data. Since blockchain development is fundamentally about working with various data structures and networks, it’s crucial that the developers have an indubitable knowledge and skills about them.

Web Development 

Blockchains are mostly used to create web apps. This is why the developer must have in-depth knowledge about web development as well. They must be well acquainted with all its various aspects including web design, development, and integration. It is essential that they possess all this knowledge since DApps or the decentralized apps (apps created with blockchain at the backend) are a more advanced version of basic web applications. Iif the developer struggles in developing simple web apps, it’s hardly possible they can create blockchain apps easily.

Socket Programming 

You should also ensure that the developer(s) you hire for the blockchain project has a clear understanding and knowledge on socket programming. A socket is a connection point in a network that connects two nodes together. With socket programming, the developers are enabled to utilize socket APIs that allow different nodes in a network to interact with each other. 

Core Programming Languages  

Till now we have discussed the conceptual technical skills necessary for blockchain development. However, mere concept cannot build any application. The blockchain developers need to be exceptionally skilled in writing codes. Here are the fundamental programming languages a blockchain developers must know-

  • Python: Python is the most popular programming language for blockchain and blockchain application development. The factors like it’s easy to learn and integrate with programs in different languages, it’s versatile and can be used to create applications on various platforms, and that most next-gen solutions around IoT and data science are created through it, make it a great choice for blockchain app development. Python can easily be used to create both front-end and back-end of an application, that means a python developer alone is sufficient to create a small blockchain application without any additional help. The thriving and ever-growing community of blockchain developers also contribute in making it a perfect choice, since it ensure that blockchain applications developed in python can remain long standing with ample support in foreseeable future.
  • Java: Java is yet another popular choice for blockchain developers that allows them to work on various platforms, by simply integrating the latter with JVM or Java Virtual Machines that that provides runtime environment for java codes independent of the platform. Another reason Java makes for a great blockchain programming language is its capability for creating complex solutions. No wonder it is among the only few languages in which cryptocurrencies are created. One more reason for this choice is that Java has been around for the longest time. It has a huge community, and many years of contributions that makes it one of the most robust, reliable, scalable, and secure programming languages of the day.
  • C++: Another popular language among blockchain developers is C++. Since C++ is the best-known programming language with OOP structure that functions closest to the hardware of a system, it naturally becomes a great pick for applications that function on dynamic data structures like blockchain. Another fascinating fact that makes C++ so popular in the blockchain realm is that it’s the language that developers used to create the core of bitcoin, the best-known application till now of the technology.

These are the most commonly used languages for the development of blockchain app development, but these are not the only ones. A programmer with experience in blockchain development with variety of languages like JavaScript, Ruby, and C# would be an additional benefit. Such developers would be able to create apps with better customization and efficiency. They will know the libraries available in the different languages and will be able to pick the best fit for the given requirements.

Conclusion 

If your company wants to reap the benefits of the blockchain revolution, now is the time to start making some important decisions. Blockchain is a foundational technology that can transform workflows and the way companies make transactions. This kind of transformation requires both time and resources, not to mention professionals with relevant skills and experience. This is why, if you’re sincere in your aim of making significant changes in your workflows through blockchain, a blockchain development company is your best bet. The company will have all the resources, and more importantly the experience, required to implement develop custom blockchain solutions and implement the same sans-hassle.
