1. What do Blockchain Developers do?

Blockchain technology is now powering everything, from supply chain management and fintech to logistics and security. For instance, Axie Infinities developers have been successful with the Axie Infinity project when it has attracted many gamers from all over the world and its AXS token capitalization value has reached $2.4 billion.

Currently, the demand for blockchain developers is increasing because many companies are trying to find blockchain developers to execute new projects and advance their systems. So what exactly does a blockchain developer do?

Developers involved in the development of blockchain technology can be named blockchain developers, however, there are two types of them, which are core blockchain developers and blockchain software developers. Core blockchain developers are in charge of developing and maintaining the blockchain system’s architecture, while blockchain software developers develop applications based on blockchain architecture and protocol by handling front-end and back-end development, design, and maintenance.

The roles of a blockchain developer can include some of the followings but not limited to:

  • Analyzing and designing blockchain networks, consensus protocols and security patterns
  • Designing the network architecture used for data centralization or decentralization
  • Developing, testing and maintaining smart contracts, front-end designs, back-end systems, decentralized applications, etc.
