Apps based on the blockchain architecture and protocol are developed by blockchain software developers. Their apps are likewise based on blockchain technology. You may compare them to web developers, who make online apps employing a web architect’s products (protocol and design). A blockchain developer may also help a company develop smart contracts and web apps that are needed to create and optimize blockchain protocols and design the architecture of blockchain systems.

Types of Blockchain Developers

Developer of Blockchain Software:

They help with the creation of apps that are built on the blockchain architecture and protocol. Their apps will also be created on the blockchain. Blockchain software developers are similar to web developers in that they use web architects’ tools to build online apps. Blockchain software developers also produce decentralized applications.

Blockchain Developers at the Core:

The primary concern of core blockchain developers is the construction of a blockchain system’s architecture. They are responsible for developing the consensus protocol as well as making the majority of the decisions. They’re also in charge of network management and blockchain architecture. A core developer is responsible for the security of a blockchain network.

Qualifications required


Cryptography is the study of procedures that help protect your data from unauthorized access. There are a few cryptographic blockchain fundamentals for developers that you should be familiar with because they are necessary for blockchain development. Public-key cryptography  for example, is a vital part of the blockchain, since it serves as the foundation for all bitcoin transactions.

Smart Contracts:

Smart contracts are a common term in the blockchain industry, and they are used in almost every blockchain system. They allow two parties to trade things or services without the use of a third party intermediary. Only once both parties have fulfilled their commitments will a smart contract be finished.


Data Arrangements:

You’ll need a solid understanding of data structures. This is because blockchain developers will be dealing with a wide range of data formats on a regular basis, necessitating the creation and deployment of networks. Furthermore, data structures make up the blockchain network as a whole.

Web Design and Development:

A blockchain developer will spend the majority of his or her time creating web applications. You will have a greater understanding of all aspects of blockchain technology as a result of mastering web development, which you can then apply to designing strong web apps that leverage blockchain technology. You’ll also need knowledge of web design, app development, and programming to create better apps.


Blockchain Technology:

As a Blockchain Developer, you must be familiar with blockchain architecture. You should also be familiar with what a blockchain ledger is, what consensus is, and how smart contracts work. The three types of blockchain architecture are consortium architecture, private architecture, and public architecture.

Basic Skills required

  • Experience with software development is a bonus.
  • Experience working on open-source projects is advantageous.
  • Working with large codebases is beneficial.
  • Data structures and algorithms are well-understood.
  • Expertise in a variety of programming languages, including C++, Java, and JavaScript.
  • Understanding the operation of peer-to-peer networks.
  • A basic understanding of cryptography is required.

Roles and Responsibilities

  • Development of smart contracts.
  • Creating dynamic front-end designs for Dapps.
  • Researching, designing, developing, and testing blockchain technology.
  • Come up with new tools and technology concepts and evaluate them.
  • New solutions should be documented, and existing ones should be kept up to date.
  • Maintain and extend client-side and server-side programs that are responsible for business logic and integration.
