How to Hire a Blockchain Developer: 5 Skills to Look for

Finding the best blockchain developer can be difficult, as there are few professionals in the industry. The demand for blockchain technology has increased, so many businesses want to use it. However, there are not many companies that can provide this service. Therefore, it can be tricky to find a good blockchain development company.

Not all blockchain developers are created equal. When looking for a development team, you must ensure they have the skills and experience necessary to deliver the best possible solutions for your project.

What Is the Role of a Blockchain Developer?

A blockchain developer is someone who creates a blockchain network or develops DAPPs for the web. They must be experienced in blockchain structure and the technologies used to create a unified system.

5 Skills to Look for in a Blockchain Developer

Here are the essential skills a blockchain developer must have:

1. Understanding of the Blockchain Architecture

Blockchain technology is a distributed ledger that enables peer-to-peer transactions without intermediaries. In addition to reducing transaction costs, the decentralized ledger is resistant to tampering and more secure than traditional payments. 

Therefore, when assessing a blockchain developer, ensure they have a fundamental understanding of the technology. For instance, an NFT developer should be aware of the architecture of different platforms, like Ethereum and Solana.

It’s important to ensure that the blockchain developers you’re considering understand how it works. This includes hash functions, consensus, cryptography, and digital agreements.

2. Experience with Data Structures and Algorithms

A blockchain is a decentralized network that relies on data structures to store transactions. Each block in a blockchain is a data structure that contains information about transactions. To find a good blockchain development company, look for a company that is familiar with data structures and knows how to use them in a decentralized network.

An algorithm is a set of instructions a computer will follow to complete a task. Algorithms can be simple, like adding two numbers together, or more complex, like those used in the blockchain industry. Some famous algorithms used in the blockchain industry include Proof of Work (PoW) and Proof of Stake (PoS).

3. Use of Programming Languages

The programming languages used in blockchain technology depend on the network launching the blockchain ecosystem. However, most blockchain developers need to understand at least two languages deeply. The most common languages used include Java, C++, and JavaScript. Finding developers with experience with object-oriented programming, models, and development libraries is important.

4. Knowledge of Distributed Ledger and P2P Networking

When developing a blockchain application, the developer you want to hire should understand how a distributed system and peer-to-peer network function. The knowledge helps such developers to create blockchain apps (Dapps).

5. Understanding of Digital Contracts

A smart contract is a computer protocol that verifies, facilitates, or enforces the negotiation or performance of a contract. Smart contracts allow the performance of credible transactions without the need for third parties. These transactions are trackable and irreversible.


Hiring a blockchain developer can be a great way to ensure that your company can take advantage of the many benefits of blockchain technology. However, it is important to remember that blockchain developers are in high demand and can be difficult to find. Additionally, blockchain developers typically command high salaries. As such, it is important to research and ensure that you are hiring the best possible candidate for the job.
