There are blockchain foundations and education institutes that fund people who want to pursue advanced research into blockchain technology.

What Does a Blockchain Developer Do?

The role of a blockchain developer depends on the company and the services offered. For example, a developer hired to create a decentralized application has different responsibilities from someone hired to develop a stablecoin or cryptocurrency. It also depends on whether you’re a core blockchain developer or a blockchain software developer.

Some common tasks of blockchain developers are outlined below.

Creates Blockchain Architecture

Core blockchain developers design the foundation for blockchain technology. This foundation is called blockchain architecture, and it includes elements like nodes and blocks. Each blockchain is unique, and the type of architecture required depends on the blockchain.

EC-Council offers a Blockchain Certification Course (CBP) that covers the fundamentals of blockchain architecture. Also, 101 Blockchains offers the Certified Enterprise Blockchain Architect Course (CEBA).

Develops Cryptocurrencies and Stablecoins

Blockchain developers may also be employed or take up an entrepreneurship project to develop cryptocurrencies. After all, the first use case of blockchain technology is cryptocurrency. So, it makes sense that one of the job descriptions of blockchain developers is creating cryptocurrencies.

Coursera has a free online course for beginners who want to learn about cryptocurrencies titled Bitcoin and Cryptocurrency Technologies. The course is offered in partnership with Princeton University.

Collaborates With Managers

Blockchain developers often work with a complete team made up of many developers. Apart from working with other developers, you will need to collaborate with managers to develop strategies to improve an existing blockchain.

Blockchain developers work on things like scalability and security. Any course on collaboration and teamwork in the tech industry will help you in this regard.

Essential Blockchain Development Skills

Whether you go to school or not, learning some skills makes it easier for you to become a blockchain developer. There are online courses that can help you to pick up these skills.

Below are the top three skills for prospective blockchain developers.

Cryptography

You will need to use and understand cryptography. It is the most common method used by blockchain developers for encoding and decoding data. In addition, most cryptocurrencies, including Bitcoin, use cryptography.

You must learn how to use cryptography for sensitive data during cryptocurrency mining and when you want to generate private-to-public blockchain keys. In collaboration with Stanford, Coursera has an online cryptography course that offers a certificate of completion.
