Understanding the blockchain technology

Grandmas vs. blockchain

How would you explain blockchain technology and its importance to someone who has never heard this word before?

Sounds like a perfectly transparent and reliable accounting tool, doesn’t it?

So, what does a blockchain software developer do?

In brief, they create protocols under which blockchains operate, design blockchain architecture, build web applications that utilize blockchain technology, and create smart contracts for recording agreements between people or companies into the system. And a blockchain mobile app developer can put all that right into your smartphone.

Now, it’s time to educate your grandma.

What’s the fuss around blockchain devs?

Blockchain technology simplifies transactions between individuals and business entities. No middleman, automatic verification, public visibility, security –– sounds too good, but it’s true.

Because of the technology’s advantages, people who can design and build blockchain networks are in demand. If you try looking for a blockchain developer in 2021, you will discover that they are not that easy to find and hire.

Of course, platforms like Upwork or Freelancer are full of blockchain developers. But, are you going to trust such a complex and intimate project as a digital ledger to a random person from the internet?

The part that busy people skip:

Why you don’t want to hire blockchain developers yourself


No, we don’t mean that blockchain devs eat hallucinogenic mushrooms and get trapped in illusory worlds.

We mean that just like mushrooms, it’s quite a quest to find a blockchain developer.

Mushrooms don’t grow in the plain sight. Blockchain developers don’t hang out on regular job boards or on LinkedIn.

Some mushrooms are edible, some are poisonous. Without knowing what exactly you are looking for, chances are you hire a scammer or a newbie instead of a competent blockchain developer.

When picking mushrooms, you want to seek under the trees or in the bushes. When looking for blockchain developers, you want to attend hackathons, explore blockchain communities, and visit blockchain events. But good luck with that in 2020.

Okay, enough of this weird analogy.

Everyone’s busy

When you try to hire blockchain developer, you discover that the blockchain technology is even more popular than you thought. And the developers who can build Dapps or create smart contracts are few.

This is a very frustrating proportion! Often, when you manage to find a blockchain developer, chances are they are already engaged in another project.

Or projects.

Get in the line.

Not all blockchain developers are in it for the money

Even if you found a blockchain developer available for hire, they might simply refuse to work for you.

Many blockchain developers don’t chase paychecks, and would rather work on interesting projects. If they think yours is boring, you’ll have to search for someone else. Did we mention that hiring a blockchain coder is a pain in the neck?

You will have to test their competence yourself

So, even if you manage to hire blockchain developer, how do you know this is the right developer for the job? How do you evaluate blockchain developer skills, their expretise, and portfolio? The problem is, you’ll have to either trust the blockchain developer you found, or to dig deeper into the subject.

Skills and expertise you want blockchain developers to have

For starters, there are core blockchain developers, and blockchain software developers.

Core blockchain developers design the blockchain system in general.
In brief, they:
  • create its architecture and the protocols under which it functions
  • write algorithms for maintaining data consistency across the whole system
  • develop security measures
  • supervise the network.
Blockchain developer roles and responsibilities are different. Their job is to:
  • develop the back end part of the blockchain system
  • design decentralized applications (DApps) for users to interact with the blockchain system
  • create smart contracts
  • create smart contracts

Regardless of specialization, you want your blockchain developer to know how data structures, cryptography, and P2P-networks work. They must also be familiar with C++, C#, Scala, Python, JavaScript, SQL, and other technologies.

How do you make sure blockchain developers you possibly find have these skills?

If you’re hiring blockchain devs for the 1st time, it can cost you a lot

Blockchain developer salary is a painful subject. Developers experienced in blockchain technology request astronomical salaries. The price depends on the region, but in general, you should not expect blockchain developer salary in the United States to be lower than $130,000.

The highest blockchain developer salaries are in California, with the most expensive devs living around the Silicon Valley. Here you can hire an in-house blockchain developer for $171,450 per year.

Los Angeles is only $9K more affordable with the average salary of $162,060, and is followed by San Diego, where devs working with blockchain expect you to pay them $157,500 per year.

Dallas looks like the area with the most affordable developers –– a blockchain expert here will cost you $131,250 annually.

As you can see, a blockchain developer salary in the United States can easily go off the scales –– at least when it comes to working with in-house pros.

Does it mean you can’t build a blockchain without spending a fortune?

Absolutely not.

Here is how you can lay your hands on some of the best and the most affordable blockchain developers.

Save hundreds of $$$

Don’t break your piggy bank yet! You can totally afford to hire blockchain developer from us, because Lemon’s hourly rates are much lower than in the United States.

Let’s roughly estimate the hourly rates in the US.

Based on the stats above, the average salary of an American in-house dev working on blockchain projects is $151,350 per year. Given that it’s 261 work days in a year, this is approximately $72,5 per hour (without tax deduction).

Lemon’s blockchain developers work for the average hourly rates of $40-$50.

Keeping our rates that low is easier than you might think:

as most of our developers live in Eastern Europe, their costs of living are about 40% lower than in the United States
our commissions are lower than our competitors’
we are a distributed team working from several countries, so we don’t need an office
our maintenance costs are mostly salaries
our overhead expenses don’t exceed $60,000

As a result, we can supply you with some extra-good devs for reasonable prices, and have enough money left to put some butter on our bread.
