Top Blockchain developer skills in 2023
As Blockchain is a relatively new technology, finding experienced Blockchain developers for hire can be tough. Yet, there are some essential skills that every candidate should possess. Let's take a closer look at them.
Blockchain architecture. When you hire a Blockchain developer, you should ensure they are well-versed in the technology's inner workings – how it functions and what it entails. With that in mind, it's a good idea to check their understanding of such Blockchain staples as consensus, distributed ledger, cryptographic hash functions, etc.
Cryptography. This is an essential skill for enabling cryptocurrency transactions in a Blockchain network. Cryptography relies on the encryption of data to protect it from unauthorized access.

Smart Contracts. For many Blockchain business models, it's essential to integrate Smart Contracts into their systems. If it's exactly what you need, ensure your candidate has an understanding of principles and skills related to Smart Contract creation.
Solidity. Strong Solidity developers are essential if you have an Ethereum-based project. Thus, make it a point to put your candidates to the Solidity test as well.
Web development. Many solutions come in the form of Blockchain app development. If that's your case, check if your potential Blockchain developer for hire knows how to use web app development tools to design, develop and write code for web applications.
Knowledge of object-oriented programming. Blockchain development relies on the principles of OOP that help find elegant solutions to complex tasks. Thus, select Blockchain developers with experience in troubleshooting polymorphism and modularity.
Ways to hire Blockchain developers
If you are building a Blockchain development team from scratch, you may wonder how to do it properly. Below, we gathered several options that will help you access and hire Blockchain developers for your organization.
Freelance Blockchain developers
Freelance platforms such as Upwork and Fiverr are ripe with Blockchain developers for hire. However, looking for professionals through them can be akin to trying to find a needle in the haystack. In many cases, working with freelancers contradicts internal security policies. Moreover, managing freelancers can be challenging if you don't have enough resources for it. Thus, it only makes sense to cooperate with freelance Blockchain developers if your project is short-term.
In-house Blockchain development teams
On the other hand, if you deal with a long-term project, it can be reasonable to build a local Blockchain development team. By hiring developers in-house, your business gains more control over the development process, however, it requires significant investments.
If the cost of hiring locally doesn’t pose a problem for you, you can post a vacancy on one of the platforms for employers, for example, Indeed, Jooble, LinkedIn, etc. Though they may not be tailored to Blockchain development, they are popular among job seekers. To make sure relevant candidates find you, optimize the job posting with specific keywords, for example, "Blockchain programmer" or "Blockchain dev." A well-written job posting will help you find and hire Blockchain developers faster. When creating the job post, you may want to include the following:
- Describe your company, project, and your goals;
- Outline the tasks your Blockchain developer should solve;
- List skills you need your applicants to possess;
- State must-have years of experience;
- Describe the main responsibilities of your Blockchain developer.
When you have a pool of candidates, prepare to interview them. The interview questions should cover the Blockchain developers' skills as well as their cultural fit. Some examples of questions may include the following:
- How many years of commercial experience do you have with Blockchain?
- What are the main challenges of Blockchain development?
- Do you have experience in Blockchain app development?
- Are you familiar with cryptography in Blockchain?
- What programming languages for Blockchain do you work with?
- What project management tools do you use in your work?
Interviewing potential Blockchain developers can be a time-consuming process. Fortunately, there's a leeway – you can hire a firm that can provide pre-vetted experts in Blockchain development.
