How To Hire Blockchain Developers [Guide]

Forecasts indicate that the market for blockchain technology will increase rapidly over the next few years, reaching a value of over $39 billion by 2025. Given the potential of the technology and the broad industry interest in the capabilities it may offer, hiring blockchain developers has become problematic.

In this article, we will cover all the essential things to consider when you want to hire blockchain developers. 

We’ll also introduce WeSoftYou, a trusted blockchain development company with expertise in blockchain, cryptocurrency, fintech, and mobile development (see how we built  Good Dollar and NDAX below).

Blockchain Developer Tech Stack and Expertise

In the technologically advanced days, hiring a blockchain developer is all but necessary. Here are the qualifications your prospective applicant has to possess.

Programming Skills

Make sure the blockchain engineers you hire have a foundational understanding of programming. They don’t have to be experts, but they should know how to create code and comprehend the grammar. Knowledge of Java, C++, C#, Python, Golang, and JavaScript are necessary for blockchain app developers.

Blockchain developers must stay current with the most recent updates because blockchain platforms like Ethereum and Bitcoin are continually changing. They should know how to work on well-known blockchain platforms.

Knowledge of Security and Encryption

A crucial component of blockchain technology is cryptography. To construct safe applications and systems, a blockchain coder must have a solid grasp of cryptography. Additionally, they need to be knowledgeable about security and encryption protocols like Secure Sockets Layer (SSL) and Transport Layer Security (TLS). Furthermore, they must understand how to use security tools like data encryption and multi-factor authentication (MFA).

Blockchain is a distributed database, so blockchain developers should know networking principles like peer-to-peer networks, packet transport over the internet, routing, etc. For a blockchain developer, having a firm grasp of cryptography, security protocols, and networking principles are crucial.

Data Structures

When you hire crypto developers, you need to ensure they are knowledgeable about data structures, including their kinds, uses, and interactions with the network. Understanding data structures is crucial because blockchain consists of them.

• Linked List. It is a data structure that linearly stores several values. Each value includes the value of the corresponding node, data, and a link to the subsequent node in the list.
• Singly Linked List. It is a linked list of the unidirectional variety. Each node in a singly linked list has only one pointer to another node, and it can only be traversed in one manner.
• Hast Table. It is a unique data structure where a hash function determines the relationship between an element’s value and location. It stores pairs of keys and their values.
• Acyclic Graph. It is a memory-efficient and quick word retrieval data structure frequently employed in natural language processing and other scenarios requiring a quick, small collection.

Blockchain Fundamentals

Blockchain technology developers need a solid understanding of blockchain architecture and concepts like cryptography, native tokens, decentralized applications (dApps), consensus, smart contracts, and hash functions.

• Distributed ledgers. A network of devices or nodes houses an electronic database system. It is unique because there isn’t a single supervisory authority.
• Consensus mechanisms. It is a mechanism that ensures that specific rules are followed and that the transaction happened as intended. In a distributed network, it enables programs to coordinate their operations.
• Smart contracts. An algorithm builds a set of instructions into the blockchain code. The sequence is automatically started if the established agreements stated in it are followed.
• dApps. These are mobile applications that utilize blockchain for any purpose. A qualified blockchain expert needs to have a background in dApp creation.
• Immutability. Once produced, data on a blockchain can’t change. Data immutability is crucial. Thus blockchain developers must be aware of its significance.
• Sharding. Sharding the blockchain network is necessary to split it into smaller units. Each shard is unique, independent, and entirely composed of its own data.
• Tokens. Blockchain technology accounts for the tokens, and specific software with a digital signature can access them. Maximum ownership rights protection is therefore guaranteed.

Blockchain Tools

A blockchain developer needs to be knowledgeable about various development tools if they wish to advance in their profession. Among those tools, we should mention Blockchain Explorer, Caliper, Composer, Drizzle, Etherscan, Ganache, Geth, MetaMask, Mist, Remix IDE, Solidity, Solo, Testnets, and Truffle. 

Blockchain Developer Requirements and Years of Experience

Degrees in computer science, information security, software engineering, or a related field are frequently held by blockchain developers. There are other ways to get ready for a job in blockchain app development than getting a degree. Candidates with certificates in pertinent specialties may be accepted by employers or even given the job preference. For developers switching to blockchain development from a related field, there is an option to expand on prior experience with blockchain-specific courses.

Based on the years of experience in blockchain development, engineers are considered: 

• Entry-level blockchain developers (1-3 years of experience).
• Middle blockchain developers (4-6 years of experience).
• Senior blockchain developers (7-9 years of experience).

How to Hire a Reliable Blockchain Developer

If you have decided to hire a blockchain developer by yourself, these steps will help you to make a balanced choice. 

Create a Job Post

When looking for blockchain developers, you must create a job post. To draw in the best candidates for the position of blockchain engineer, the job post must be comprehensive and carefully curated to include the following:

• Your company’s mission and purpose.
• The skillset you are looking for.
• Required experience.
• Duties and responsibilities.
• Type of employment.
• Salary range and other compensations.

Inform potential applicants upfront if there are any challenges so they won’t waste their time applying if it is not a suitable fit. Once you have found decent candidates, prepare interview questions and arrange interviews. 

Conduct Interviews

The interview aims to assess how well people will get along and determine whether the applicant is qualified for the position. While asking questions during an interview can help you learn more about your candidates’ personalities and thought processes, it’s also crucial for them to understand how approachable and welcome you are as their potential boss.

Here are some of the questions you can ask at the interviews: 

• When did you start working in the blockchain industry?
• What difficulties do you foresee in putting blockchain technology into use or adopting it?
• Do you have experience developing blockchain applications? If so, could you please elaborate?
• How would your knowledge of cryptography apply to working with blockchains?

Arrange Coding Challenges

Understanding how blockchain operates and what makes it unique and better than other technologies is one of the coding challenges. You need to check how the candidates understand the guiding principles of decentralization, security, immutability, consensus, and openness. 

Ensuring blockchain engineers are aware of blockchain fundamentals and willing to grow their skill sets as needed is crucial when hiring them.

3 Things to Consider When Choosing a Blockchain Development Provider

What if finding a blockchain developer becomes an extensive search and you don’t want to hire blockchain developers yourself? It is where a blockchain development provider comes into play. A blockchain development company can provide a ready blockchain development team with the required experience and expertise. But how to choose the right provider? 

We have prepared some tips to help you be prepared to make an informed decision on your blockchain development partner.

Portfolio

You can get a sense of a company’s level of quality by looking at their prior work. Your best choice is to work with a blockchain development business that has a strong portfolio. A major warning sign is a splendid website lacking a portfolio of prior work. Therefore, request a list of the company’s blockchain development services that were provided.

Clients’ Reviews

Client testimonials from the past are meaningful. Positive feedback from prior customers demonstrates that the business offers high-quality solutions. Contrarily, unfavorable testimonials imply that the company’s services are of poor quality. You would be wise to avoid dealing with such a company.

Type of the Technology the Blockchain Company Uses

The blockchain functionality varies even if they have the same fundamental premise. Blockchain-based solutions with different purposes include, for instance, Ethereum and Ripple. Ripple is a mechanism for token transmission, whereas Ethereum focuses on smart contracts. You need to choose a blockchain development company specializing in technologies that satisfy your business goals.
