When you think of blockchain, you probably picture it as the backbone of a cryptocurrency such as Bitcoin. But blockchain is more than just a digital currency,it's a technology that can provide a wide range of benefits for businesses.
For example, blockchain can help businesses with supply chain traceability. This is an important issue for companies like Amazon, whose products are often sourced from other countries and then resold by third parties. Blockchain can help identify problems with these transactions and ensure that they're being conducted correctly.
Blockchain also provides information security, which is especially useful for companies in industries like finance or healthcare where patient data is highly sensitive and valuable.
Finding, attracting and hiring blockchain engineers will remain one of the top challenges facing companies in the industry. Follow these steps and you'll be on your way to finding, vetting and hiring the best blockchain engineers. Top sites for recruiting blockchain engineers can also be used for help.

1. Understand what blockchain technology is and how it works
Blockchain technology is a distributed database system that uses cryptography to secure data transfer. Cryptography is a method of encoding information to make sure only authorized users have access to the data. In addition to securing data, blockchains allow for transparency and immutability. Immutability means that once something is recorded on the blockchain, it cannot be changed. Transparency refers to the fact that anyone who wants to view the transaction history can do so.
2. Identify the different types of blockchain developers
There are three major categories of blockchain developers: full stack developers, front-end developers, and back-end developers. Full stack developers build applications using both front end and back end technologies. Front-end developers focus on building user interfaces while back-end developers focus on developing the core functionality of the application. Back-end developers work closely with the business side of the company to understand the requirements of the project.
3. Determine if blockchain technology is right for your business
Before hiring a developer, ask yourself these questions: Do I need a decentralized network? Is my product/service open to the public? Does my industry require a transparent ledger? If the answer is yes, then consider using blockchain technology. Blockchain technology is a hot topic right now. But just because you've heard about it, doesn't mean you should use it.

4. Create candidate persona to hire better.
Ask about their previous projects
Find out what type of apps they built and whether they were successful. Also, ask if they have any relevant certifications. Certifications show that the person knows how to code and can implement solutions efficiently.
Ask yourself if this particular candidate has any relevant experience in what type of project(s) they'll be working on at your company, especially if those projects involve blockchain technology! You want someone who knows how it works
Get references
Ask around to get recommendations from friends and colleagues. References are great ways to gauge a developer’s skills.
Look for a team player
A good blockchain developer should be able to work well with others. They should be willing to collaborate and share ideas.
Perform a thorough background check on candidates before making any offers or extending them an offer letter so that you can be confident about the level of professionalism and trustworthiness in the candidate's work history and references.
Key concepts to look for
Every blockchain developer must understand fundamental blockchain concepts and have hands-on experience with them. When creating your candidate persona, keep the following essential blockchain developer skills in mind:
Cryptography is one of the core skills that your candidate must be well-versed in. The study and application of cryptography determine how well a blockchain works.
Smart contract: This is one of the most frequently used terms in the blockchain industry, and almost every blockchain solution makes use of it for its benefits. In layman's terms, it allows two stakeholders to exchange goods and services without the need for an intermediary.
Data structures: Every blockchain developer must know and understand data structures on a daily basis because they are used to build networks.
Web development: Depending on your needs, a blockchain developer will most likely create web applications to integrate with blockchain technology.
Blockchain architecture: Understanding the importance of a ledger in blockchain, the definition of consensus, and how smart contracts work is critical for blockchain developers..
Interoperability is the ability to view and collect information across multiple blockchain systems, which is essential for a developer.

5. Evaluate your Hiring Practices and Evaluation Methods
Define your evaluation methods. What kind of questions are you going to ask during an interview? What will get you closer to a yes answer than an ambiguous one? How will you know if a candidate is right or wrong for your company? Furthermore, evaluating your company's hiring practices entails determining the best tools, methods, and budget for hiring a blockchain developer. These three categories will be determined by the type of agreement you have with your new developer.
Next, you must be crystal clear about the type of blockchain developer you require: freelancers, full-time remote developers, or onsite developers.
Freelancers
People frequently associate freelancers with low hourly rates. It's true in some cases. However, if you want a good job, don't expect to get it by paying low hourly rates. Freelancers owe you no loyalty. Working with freelancers means collaborating with someone outside of our organization.
Full-time remote developers
Working with remote employees often necessitates being deliberate about communication. Because you can't see them in person, make sure nothing gets lost in translation and that misunderstandings are avoided by being specific about projects and tasks.You can find out whether you ned a remote developer for your startup or not by taking further help from hiring sites.
It's not as simple as it appears. One advantage of remote hiring is that you have access to a larger talent pool. However, this does not imply that finding the right candidate will be simple. You still need to improve your hiring methods and processes.
Onsite developers.
Hiring onsite means you have a limited pool of candidates to choose from. Keep in mind that blockchain is a highly specialized area of software development, which further narrows the pool of talent.
Hiring a blockchain developer in the United States is likely to be prohibitively expensive. This is something you should always keep in mind when developing a realistic budget, and because you're focusing on one area, few candidates may be willing to adjust to your demands.
6. Consider challenges with implementing blockchain
And while the benefits make your eyes shine bright, take a moment to analyze the essence of blockchain.
1) Data modification: Once something has been written to the blockchain, it can never be changed or deleted, even if the person who wants to make changes later on does not have access to the original information anymore. That means that once something has been written to the blockchain, no changes can be made without completely destroying the integrity of all transactions that have ever been made in this particular instance (which would render any future transactions invalid).
2) No privacy: Your data is visible to everyone else who has access to your network (meaning anyone with access at all), which means that if someone wants access to any information they'd need only one person's permission. This obviously isn't ideal for sensitive information like personal health records or financial information
