Blockchain is a revolutionary technology that is popularly known as the backbone of digital cryptocurrencies, which have been generating incredible hype in the last decade. Blockchain started as a way to store and secure digital data. It is an open ledger that several parties can access at once. One of its primary benefits is that the recorded information is hard to change without agreement from all parties involved. Blockchain technology is among the hottest skills to learn these days. In this post, we have laid out the best online courses on blockchain technology.
What is Blockchain?
Blockchain is nothing but a set of blocks that are open to anyone and contain information and the hash of the block and some other info. Every block will store information depending on its work for instance if that block is used for money transactions it will store the information of the sender and receiver and the amount of money that is transferred.
In simple terms, it can be termed as a Distributed Database authenticated by a wider community instead of a single-control authority. As the name suggests, it is a chain of blocks.
The blocks carry information. Each block constitutes the cryptographic key to associate with a previous block and its resident data. Though everyone can access this data, only authentic parties can create it.
These blocks are chained together to ensure authenticity in adherence to cryptographic principles. These blocks are immutable as once formed they cannot be modified.
The national average salary for a Blockchain Developer is ₹6,91,082 in India. Blockchain Developer salary in India ranges from ₹ 2.2 Lakhs to ₹ 20.0 Lakhs with an average annual salary of ₹ 6.5 Lakhs.
Today, Blockchain is one of the fastest-growing skill sets with jobs in this domain growing at a mindblowing rate of 2,000-6,000% and the salaries of Blockchain Developers being 50-100% higher than conventional developer jobs. Read more about Blockchain Careers and Jobs.
In-Demand Blockchain Skills
The most in-demand Blockchain skills right now are Hyperledger, Solidity, Ripple, and Ethereum. However, since this space is relatively new, companies often settle for professionals with a specific skill set. For instance, Blockchain Developers must have a basic knowledge of mathematics and algorithms. They must be well-versed in C, C++, Java, and Python since a majority of Blockchain projects are written in these languages.
Blockchain Developers must be aware of at least a few tools required for Blockchain development such as Geth, Remix, Mist, Solium, Parity, BaaS, and Truffle, to name a few. Also, they should have some experience in working on open-source projects. Usually, most companies hire Blockchain Developers having at least a bachelor’s degree in Mathematics or Computer Science.
