Learn Everything You Need to Know While Hiring Blockchain Developers

Blockchain technology was developed in 1991 but it came into effect in 2009 after launching the first blockchain-based cryptocurrency called Bitcoin. The complex nature of blockchain was hard to learn but as technology evolves things have become relatively easier. If you think to hire a blockchain developer, you need to understand its fundamentals from the beginning.

Why the need for blockchain developers is on the rise?

The demand for blockchain is increasing at a rapid pace. In 2016 there were only 5000 developers dedicated to writing cryptocurrency software but today the numbers are increasing tremendously. More and more people are learning to program blockchain as it is a promising technology with tremendous futuristic prospects.

In the first quarter of 2020 LinkedIn listed blockchain as one of the most demanding technology. It was the first year that blockchain was at the top of the list.  Today, blockchain software developers are in high demand and it’s going to be more in the coming years.

Why you must hire a blockchain developer?

In 2019-2029, blockchain developers are among the fastest-growing professions according to the US Bureau of Labor Statistics. According to LinkedIn, blockchain is a crucial skill that a developer must possess. A hiring specialist described blockchain engineers as the “dark horses” of 2019 and predicted an increase in demand for them in the future.

Full-stack blockchain developers are responsible for the following tasks:

• The purpose of this research is to determine the client’s expectations and needs regarding the functionality of an application or platform.

• Consider how blockchain technology can be used to upgrade existing platforms by evaluating new blockchain technology.

• New blockchain applications should be developed (frontend and backend).

• It is important to write code that is clean and effective.

• A threat assessment (e.g., keys without protection, software without testing).

Is there a need for Blockchain Developers?

An individual who develops blockchain-related software is referred to as a Blockchain Developer. The role of a Blockchain Developer often overlaps with those of Software Engineers, Product Managers, Designers, and Data Analysts. You don’t need to hire all blockchain programmers for these roles in your organization, even if it’s beneficial to have all of them. Your project’s stage and the timeframe for its completion will determine how quickly you can start.

For hiring a blockchain developer, what soft skills should to look?

Hiring blockchain app developers is not an easy task. You need to check several skills. The skills required to become a qualified blockchain developer are diverse. It can be challenging to determine which skills are most important to pursue when starting a blockchain development career.

Candidates can learn some details about what employers look for by reading job postings, but these “requirements” tend to be tailored to each company’s requirements. There are many skills that a blockchain software developer must require but the most important four essential skills are-

• Cryptography

  Blockchain environments require effective cryptography, so developers should have a strong understanding of wallets, keys, and digital signatures. Cryptographic hash functions like SHA-256 and Keccak-256 should be understood to prevent unauthorized access to data using public-key cryptography.

• Data Structure
  
  Blockchains are cryptographic data structures. Two of the most popular types of blockchain databases are UTXOs (for Bitcoin networks) and accounts/balances (for Ethereum networks). To develop a blockchain, developers need to have a good understanding of these concepts and how data structures work.

  Computers use algorithms to perform tasks. Problems are solved and tasks are performed with them. In the blockchain industry, consensus algorithms such as Proof of Work, Proof of Stake, and Delegated Proof of Stake are popular.

• Smart contracts

  Contracts self-executing own are known as smart contracts, and it offers secure multi-party agreement solutions using a blockchain network without any intermediary involvement. Developers should understand how smart contracts enforce business logic, and what they are in blockchain implementations.

  A blockchain developer should also know how to program smart contracts using programming languages such as Chaincode, Solidity, Rust, JavaScript, and Vyper.

Blockchain Interoperability Skills

For a blockchain to operate effectively, it needs to be interoperable with other blockchain protocols. The use of different blockchain networks is made easier by the ability to interact between different chains and share data. 

Let us take an example of emails. Daily, emails are received and sent. But one of the significant functions of the email system is the Outlook account. Someone with an Outlook account can send emails to a Gmail account holder.

The most fundamental way to accomplish interoperability between blockchains is a seamless and effortless data transfer process. It is accomplished by using the application programming interface which is to be developed to exchange information with each other.

However, the new projects are working on these ideas and trying to build platforms so that better communication could be built without any inconvenience.

Final Thoughts while hiring Blockchain Developers in 2023

More and More businesses will adopt blockchain technology in 2023. So you need to filter the applications of blockchain developers in a more sensible and conscious manner.
Blockchain requires a wider set of deep analytical skills and greater problem-solving capabilities.

As you build your understanding of the behavior of Blockchain developers including their work output, you’ll surely be able to handle your team of blockchain developers and your company will function in a more synchronized way.
