What Does a Blockchain Developer Do?

The wise yet short answer to this is: a Blockchain developer develops Blockchains! Well, that was easy!

Blockchain developers enable secure digital transactions by creating systems to record and store blockchain data in a way that prevents changes or hacks. They design secure blockchain technologies, develop application features and interfaces, and maintain client and server-side applications.

Types Of Blockchain Developers

1) Core blockchain developers

These are in process of developing and improving architecture. The developer will be in charge of designing, developing, and optimizing the protocols that will be used to enable a blockchain solution. The consensus protocol, for example, outlines how and in what manner users of the blockchain and the resources it contains agree on sharing and utilizing these resources.

  • They also make decisions relating to such.
  • They implement the functionality and features of the blockchain and ensure that they work as intended.
  • They design and implement the security of the network.
  • They ensure the network is operational.
  • They plan, design, and implement integrations of the blockchain network with other services.
  • They plan on extending the features and functionality of a blockchain network.

2) Blockchain software developers

They develop and implement the design as per the plan by the core developer.

  • They develop dApps.
  • They implement smart contracts as per design by core developers.
  • They ensure dApps run as planned.
  • The research on and look after integration of the blockchain network with other services and apps.

Other categorizations

3) Back-end developers

These individuals may design and implement APIs, do performance tests, install blockchains, create software specifications, collaborate with other developers on software development, and give technical support.

4) Smart contract engineers

They audit and develop smart contracts, meet with users and buyers, understand business flows and security to ensure no flaws in smart contracts, and study smart contracts, do end-to-end testing of the business processes.

Why Become A Blockchain Developer

The following reasons will explain it better:

1) High demand  

Cutting edge technology and potential for growth: According to a PwC poll from last year, blockchain has a bright future, with 84 percent of organizations experimenting in the technology. Blockchain will be used by a far larger number of individuals. Only around 1% of businesses have adopted the technology, with many more considering it in the future.

2) Amazing pay

The average salary for a blockchain developer in the United States is between $150,000 and $175,000 per year. A developer’s compensation is one of the highest in the industry, according to this research. Experienced and highly qualified blockchain professionals get paid more.

3) Ability to teach others

Jobs and training as a blockchain developer might open up new revenue sources by teaching others how to work on the same platform. They can, for example, educate using online instructional platforms.

4) They get to understand crypto, ICOs, etc, and how they and their companies can raise capital using new revenue streams with crypto.

5) Improved digital identity and security

Blockchain has more promise for businesses looking to safeguard their operations and platforms than traditional non-blockchain platforms.

Blockchain platforms and processes such as digital identities also help cut down the process and operational costs for developers and their organizations.

6) Contribute to other new-age technologies

Blockchain integrates with other technologies such as IoT.

Roles of a Blockchain Developer

Let’s first discuss the roles of a core blockchain developer.

Core Blockchain Developer

As discussed earlier, a core blockchain developer is generally involved in the design, architecture, and security of a blockchain system. In brief, their roles include the following:

  • Design of blockchain protocols
  • Design of consensus protocols and security patterns for the network
  • Design of the network architecture
  • Supervision of the entire network

Blockchain Software Developer

Developers of blockchain software have their own set of responsibilities. These responsibilities have nothing to do with the system’s consensus design or architecture. Blockchain software developers create decentralized applications or Dapps using blockchain technology, just way a regular web developer uses the protocols and architectural structure set up by a core web architect to build web apps. Their responsibilities include:

  • Development of Smart Contracts
  • Development of interactive front-end designs for Dapps
  • Backend development pertaining to Blockchain
  • Supervision of the entire stack running their Dapps.

Now that, I’ve told you guys about the different types of blockchain developers and their respective roles, let me tell you guys about the technical knowledge and skills required for you to bootstrap your career as a blockchain developer.

Top Blockchain Developer Skills 

Blockchain engineers, as you’ve already seen, have a lot of duties. They’ll need a few skills to be able to manage such responsibilities effectively. In order to be a good blockchain developer, certain skills must be developed and mastered. To face and manage blockchain development, you need have the following key blockchain developer abilities.

1) Cryptography

Cryptography is the study of protocols that prevent unwanted parties from accessing your data. There are many essential concepts in cryptography you should be familiar with as you’ll need them during blockchain development.

For example, public-key cryptography is a crucial topic of blockchain. It forms the basis for the transactions we make through cryptocurrencies.

To perform cryptocurrency transactions, you’ll need a wallet and the key to that wallet. That key is necessary because it establishes your ownership of the wallet. Cryptocurrency transactions are secured via the encryption and decryption of public and private keys.

Cryptographic hashing is another important idea in cryptography. Hashing is the process of obtaining a particular length output from an input of any length. The hash function might store information with 20 or 200 characters, but it will only return data of the length you choose.

Certainly, cryptography is vital for the proper workings of blockchain technology. You should learn about it and its various aspects, including the topics we’ve discussed here. With its knowledge, you’ll be able to keep your blockchain data safe. 

2) Blockchain Architecture

You should be familiar with blockchain architecture if you want to work as a blockchain developer. You should understand what a blockchain ledger is, what consensus is, and how smart contracts function.

Blockchain architecture has three kinds; they are:

  • Consortium architecture

The consortium’s design isn’t entirely decentralized. The members of a group have complete control in this situation. The group in these circumstances is made up of many organizations. The Energy Web Foundation is a great example of this sort of blockchain design.

  • Private architecture

Only a few people are involved in a private blockchain architecture. It’s a widely used application in businesses. Sawtooth and Fabric are two well-known examples of this type of architecture. Another important characteristic of such design is that it is not decentralized.

  • Public architecture

The most decentralized sort of blockchain architecture is public architecture. You may participate in the network by mining or conducting trades. Bitcoin is the most well-known example of public blockchain architecture, and you’ve probably heard of it.

You should read the whitepaper of bitcoin on blockchain to become familiar with this topic. It requires a little effort, but be sure that it’s worth it because you’ll get familiar with all the fundamentals and the advanced concepts altogether. 

3) Smart Contracts

Smart contracts have been a common concept in the blockchain sector since the launch of Ethereum. Almost every blockchain solution seeks to profit from smart contracts. As you can see, this technology is quite strong.

Smart contracts allow two parties to exchange products or services without the need for a third party to serve as an intermediary. Smart contracts can be compared to vending machines. You make the payment, select the item you want, and receive the item along with the remaining change. There is no third party in this transaction; you and the vending machine are the only ones engaged.

Only when all of the parties involved have met both of their requirements do smart contracts come to an end. Because blockchain is decentralized, it is extremely effective. This means that hundreds of people are watching your smart contract, and because they function on an IF-Then basis, there’s a chance that something may go wrong.

You can use smart contracts in many areas of different industries, such as law, construction, and many others. It can remove the middlemen from contracts and help in saving money and resources. 

To become a blockchain developer, you should make yourself familiar with smart contracts. It is one of the essential blockchain developer skills. Multiple languages specifically focus on smart contract development, such as Chaincode and Viper. 

4) Data Structures

To work as a blockchain engineer, you’ll need a strong understanding of data structures. This is because blockchain engineers work with a variety of data formats on a daily basis since they must construct and implement networks.

The entire blockchain network is made up of data structures, as even a block is a type of data structure. A block clusters transactions for the public ledger because so it is a container data structure, whereas the public ledger is the blockchain. 

A block also contains a header, and the former is around 10,000x larger than the latter. As you can see, data structures are the fundamental concept of blockchain. You’ll need to master this topic to understand blockchain technology effectively. 

Learning about data structures can help you understand the fundamentals of blockchain. Having a solid foundation can help you grasp complex topics more quickly. You’ll be employing both of these technologies to create reliable, helpful, and secure solutions, as we’ve already discussed.

5) Web Development

As a blockchain developer, you’ll be developing web apps in most cases. Learning web development will make you acquainted with all of its aspects, and you can use this knowledge to create robust web apps that use blockchain technology.

You’ll need to study web design, app development, and programming, which will all help you create better Dapps. Because most companies want blockchain developers to design apps that users with little or limited knowledge of blockchain can use, web development is essential. Having a lot of design experience can help you a lot in this area.

6) Know the platforms

Choosing the right blockchain platform is a crucial test for the organizations today, due to a large number of systems regularly makes perplexity. Deep learning of diverse blockchain platforms comprising

Hyperledger Fabric, Ethereum, Ripple, and R3 Corda, all developed by the Linux Foundation, will be authorized to make a difference with the right use case for the right blockchain platform and well-spoken their distinctions.

7) Understand the blockchain security

For uniformity, legality, and administrative demands, security frameworks are still being developed. Public and private key cryptography, cryptographic hashing, Merkle confirmations, and elliptic bent digital signatures are all valuable security abilities.

Since blockchain isn’t a database technology, it requires a breadth and depth of capacities that each capable blockchain expert should secure as aptitudes. To be effective, you should get an understanding of blockchain standards and practices and how they can be connected inside your business condition.

7) Languages You Must Know

Blockchain development is vast. Apart from the topics we’ve discussed, you should also consider learning a few programming languages. A common question among beginners is, ‘What languages should I learn to become a blockchain developer?’ 

The following are the main languages you should learn as a part of your blockchain skills:

7.1) Java

Java is popular among blockchain developers because of many qualities. It’s simple to understand, but it’s capable of producing a wide range of complex answers. Java is used to power NEM, a prominent cryptocurrency. Java has a developer community of more than 9 million people. Furthermore, it has been in the industry since 1995. Because data mastery is necessary for blockchain development, even if Java is old, it is still important.

7.2) C++

C++ is a widely used language among blockchain programmers. With its assistance, you may complete a variety of blockchain-related activities. Because bitcoin core’s designers utilized C++, it’s a must-have for any prospective blockchain developer.

7.3) Python

Python is among the most popular programming languages on the planet. It’s versatile, and its various libraries enable you to use it for both front-end as well as back-end development. That’s why you should make yourself familiar with Python as well. 

Python has a significant community of more than 4 million developers. Such a thriving and supportive community can help you out with many problems and doubts. 

You can also learn JavaScript, Ruby, and C#, along with the languages we’ve mentioned above. Ability to learn and work on multiple languages is one of the important blockchain developer skills.

What Kind of Mindset Do You Need to Become a Blockchain Developer?

Before we dive into those two different types of people aspiring to become Blockchain developers, it may help to familiarize ourselves with the kind of mindsets that are best suited for Blockchain developers. After all, the unique challenges of Blockchain development require a certain unique way of thinking.

When you hear the word “hacker” stated aloud, it’s typically not in a favorable light; no self-respecting company wants to do business with hackers (except ethical hackers, but that’s an another tale for another time). However, it is the hacker attitude that aids in the development of skilled Blockchain engineers. When presented with issues or hurdles, hackers are more likely to think outside the box than to think traditionally.

A skilled Blockchain developer may also work as part of a team and cooperate. On a similar note, the perfect Blockchain developer understands when to seek assistance with an issue and when to persevere until they find the solution.

So the best candidate for Blockchain development works well with others, knows his or her limitations, and can unconventionally approach problems.

According to Talent, an average salary for a blockchain developer is between $125,000 and $175,000 per year. To compare, an average software engineer salary stands at $140,000 per year.
