Who is a Blockchain Developer?

A blockchain developer is essentially anyone involved in the development of blockchain networks and fundamentally trying to decentralize the web. A more specific definition would be an individual responsible for developing and augmenting blockchain protocols, designing blockchain system’s architecture, developing smart contracts and Dapps using various platforms such as Ethereum and NEO.

There are two types of blockchain developers, i.e. core blockchain developers and blockchain software developers. Core blockchain developers are tasked with the designing and developing a blockchain system’s architecture along with designing and testing its consensus protocol and also formulating crucial decisions relating to a blockchain system. Conversely, blockchain software developers are responsible for implementing the architecture and protocols designed by Core Blockchain developers in turn building Dapps that operate on the blockchain technology.

What are the Roles and Responsibilities of Blockchain Developers?

The roles and responsibilities of blockchain developers are generally categorized based on the two types of blockchain developers as discussed above. The roles of a core blockchain developer include:

    Designing blockchain protocols and the blockchain’s network architecture.

    Designing consensus protocols along with security patterns of the entire blockchain network.

    Researching and brainstorming on emerging blockchain technologies or innovative tools relating to the blockchain network.

    Participating in global blockchain community forums to be updated on latest blockchain technology development and later implementing and integrating workable development proposals. 

    Supervising the entire blockchain network framework to solving emerging problems in real time to avert costly downtime.

    Documenting discovered improvements or solutions relating to a blockchain network.

Blockchain software developers have a separate role that does not involve designing instead focuses on implementing the designs. Some of their roles include:

    Development of Dapps with their Smart Contracts based on existing models.

    Implementing Dapps’ interactive front-end designs.

    Carrying out backend developments relating to a blockchain network

    Overseeing the full stack running their Dapps.

The data structures in a blockchain network should efficiently integrate with its cryptography to ensure that the entire system is secure and immutable to unauthorized malicious entry. This said blockchain developers should have a deep understanding of data structures to design and implement not only functional but secure blockchain systems.

4.    Cryptography

Cryptography is a technique that involves developing and analyzing protocols aimed at achieving the various aspects of information security such as data integrity, confidentiality, non-repudiation and authentication. In a blockchain network, each block consists of a cryptographic hash, comprising of a timestamp and transaction data to secure the system. Essentially, the functioning of a blockchain network involves the aggregation of advanced cryptography and data structures. Therefore, a blockchain developer should have a comprehensive knowledge of cryptography. Additionally, cryptographic methods such as hash functions like SHA256 for Bitcoin demands blockchain developers to have an all-inclusive understanding of generating digital signatures using cryptographic techniques. It is impossible to develop blockchain networks without understanding asynchronous cryptography in addition to cryptographic methods.

5.    Application Development

A rich background in developing apps would be an essential skill for a blockchain developer kickstarting their career in the blockchain space. This is because as a newbie blockchain developer, you are primarily employed to design decentralized applications; therefore, you must have some knowledge on both front-end and back-end development which involves skills such as developing interactive graphical user interface for Dapps, API handling, request handling and so much more. 

6.    Knowledge of Blockchain Platforms

A blockchain developer should have a deep understanding of various blockchain platforms such as Ethereum, NEO, Linux’s Hyperledger Fabric, R3 Corda among others. Having an understanding of the different blockchain platforms is vital in selecting the right platform for the development of an anticipated blockchain network. Additionally, using a multitude of frameworks to develop a single blockchain system would lead to implementation issues as the system would not be able to reconcile their differences. Therefore, it is essential to have a basic understanding of the various blockchain platforms.
