The Role of a Blockchain Developer
A blockchain developer, in a nutshell, is an individual who develops software for the blockchain protocol architecture. Their regular work entails creating and improving algorithms that conform to and operate on the blockchain protocol, which is built on top of the standard Internet Protocol (IP) to function as the internet for blockchain-powered devices.
Sometimes the roles can vary in terms of the tasks a developer has to perform and hence, they are broadly categorized into two types.
- Core Blockchain Developer: A core blockchain developer engages with blockchain at the most fundamental level. They are in charge of creating the blockchain architecture, which entails selecting the system protocol, and the consensus mechanism.
- Blockchain Software Developer: Blockchain software developers maintain a high-level interaction with the blockchain. Their role is to utilize the algorithms developed by core blockchain developers and implement them into their own applications for creating dApps.
Apart from this, a blockchain developer’s role also involves the following:
- Building a Secure Database: Blockchain is a distributed, immutable database that can assist to reduce fraud inside of an organization.
- Improving Data Security: Data is encrypted using cryptography by the blockchain creator. As a result, hackers can no longer gain access to important data and compromise the system.
