What is Blockchain and cryptocurrencies?

Blockchain technology is the brainchild of Satoshi Nakamoto, which enables digital information to be distributed. A network of computing nodes makes up the Blockchain. Durability, robustness, success rate, transparency, incorruptibility are some of the enticing characteristics of Blockchain. By design, Blockchain is a decentralised technology which is used by a global network of the computer to manage Bitcoin transactions easily.

Cryptocurrency works on Blockchain Technology, it is decentralised, open source and a mode of peer-to-peer transaction. it is not issued and controlled by any government or central authority, unlike other payment systems.

Blockchain job market is booming and many organisations around the world are adopting the technology by creating applications of blockchain technology.

As a skill set, blockchain is a combination of existing programming technologies and concepts, such as object-oriented programming and ledger economics, with an understanding of cryptography. As such, demand for other roles, such as product managers and requirements specialists, within the industry is also growing.

If you are looking to get into blockchain as a career path then this is the time to set your goal and start learning into the subject. There are numerous blockchain related jobs that has been born in the last few years and they are sure to stay around for the future. Below are some of the popular blockchain jobs;

Blockchain Developer - the most popular of all the jobs currently in the blockchain sector. Developers are programmers whose role is to develop blockchain applications using programming languages such primitive languages like C++, blockchain programming Java, JavaScript, and Python, and new entrants like Solidity, Simplicity, and CX. Top organisations including tech firms, finance firms, and governments continue to look for blockchain developer talent.

Blockchain Architect - these are individuals whose responsibility is to design and come up with solutions for different areas of blockchain such as designing a new blockchain ledger, connecting blockchain with existing applications. Architects should be technical as well as good communicator as they require to collaborate with professionals in other departments such as IT operations, network administrators, UX designers, and developers.

Blockchain DevOps - responsibility is to create, develop, and maintain all blockchain infrastructure components. They are responsible for automating much of the infrastructure and deployment of applications. DevOps also monitors the performance of varied services and tools administered within the infrastructure. The key skillset needed are good proficiency with Linux operating system, various cloud platforms, docker & various automation tools such as Ansible & Terraform.

Blockchain Project Manager - ensures the management of blockchain project from its developers & architects to all other various business stakeholders. Project managers should have clear understanding of technical requirements and simplify these requirements to wider company areas. One should be skilful in project management as well. Besides, having communications skills is another critical aspect of this role.
