If someone wants to jump into a career that has a lot of potential for growth, featuring a dynamic new technology that’s just getting started, they can consider becoming a Blockchain Developer.

If this prospect intrigues you and you want to find out Blockchain Developers, read on this article instantly.

Types of Blockchain Developers and their tasks

Who exactly is a Blockchain Developer and what kind of development is he concerned with? It’s easy to get confused. That's because there are many types of developers out there in the industry. Therefore, let’s remove this confusion by actually defining a Blockchain Developer.

A developer takes responsibility for developing, optimizing blockchain protocols, crafting the architecture of blockchain systems, developing smart contracts and web apps using blockchain technology. Basically, any developer who involves in the development of blockchain technology can be considered a Blockchain Developer. We can classify them into two distinct types.

In fact, there are two types of Blockchain Developers, namely Core Blockchain Developer and Blockchain Software Developer. Each type has their respective roles in the industry.

Core Blockchain Developer

They are mostly responsible for developing the architecture of a blockchain system, how to design its protocols. In addition, they design consensus protocol and other high-level decisions and development related to blockchain technology.

As we know, a Core Blockchain Developer is generally involved in the design, architecture, and system security. Simply, with themselves roles, they will conduct to:

  • Design blockchain protocols

  • Design consensus protocols and security patterns for the network

  • Build the network architecture

  • Supervise the entire network

Blockchain Software Developer

Blockchain software developers will use the architecture and protocols designed by developers in Core Blockchain to build up decentralized applications. These applications run on blockchain technology.

For Blockchain Software Developers, they have a specific tasks. These tasks have no connection with consensus design or architecture of the system. It's similar to how a normal web developer uses the protocols and design structure set up by a core architect and build web apps. The Blockchain Software Developer builds decentralized applications or Dapps using blockchain technology. They will be responsible to:

  • Develop smart contracts

  • Produce interactive front-end designs for Dapps

  • Develop backend pertaining to Blockchain

  • Supervise the entire stack running Dapps

Professional skills of Blockchain Developer

When we mention a Blockchain Developer, you always recruit a person with a combination of professional skills. We will take a look at each skill as follows.

Being good at blockchain architecture

They need have an excellent knowledge of blockchain consisting of its working and its architecture. The developer should clearly understand concepts such as cryptographic hash functions, consensus, distributed ledger technology. It's good to go through the bitcoin blockchain whitepaper to get themselves familiarised with blockchain technology. However, going through the complete white paper seems to be a tedious task. The developer may need a little guidance because it helps boost the learning curve.

Being knowledgeable about data structures

A Blockchain Developer must have an in-depth knowledge and applicative sense of data structures. It is really essential when any developer aims to become a professional one. The developer constantly plays around and tweaks existing data structures like merkle trees, petrecia trees etc. This is to meet their personal network requirements. In fact, blockchain uses a lot of data structures in conjunction with advanced cryptography to establish a secure and immutable system. Therefore, if the developer has a knowledge of blockchain but lack data structures, he will be incomplete.

Being excellent at cryptography

As we know, blockchain actually is a conjunction of data structures and advanced cryptography. Therefore, it obviously requires a good grasp on cryptography, essential skill to become a Blockchain Developer. In addition to asynchronous cryptography, people also use a lot of cryptographic methods (like hash functions eg SHA256 and KECCAK256) in blockchain for generating digital signatures. As a result, if the developer does not understand how these work, he will be impossible to become a real Blockchain Developer.

Being able to develop smart contract

The fact that since the release of Ethereum, smart contracts have become a huge thing. Nowadays, every business tries to incorporate smart contract functionality into its system. This helps business logic be able to easily applied on the blockchain. Therefore, if developers are striving to get into the blockchain field, they should definitely learn about smart contract development. Typically, this requires learning network specific languages such as Solidity, Viper, Chaincode, etc.

Being outstanding at web-development

Web-development is a core skill of a Blockchain Developer. Generally, when a person starts his career as a Blockchain Developer in the industry, most of them are recruited for the basic designing of decentralized applications. Therefore, you must know the basics of both front-end and back-end development. It includes creating interactive graphical user interfaces for Dapps, API handling, request handling, etc.
