Blockchain refers to time series of immutable information or data records that is decentralized among computer or network clusters instead of being concentrated at a single node. Each of these information records, known as blocks, are tightly bound to each other using cryptographic security measures, commonly called chains. Owing to its shareable, immutable & decentralized nature, every block is publicly available; this notion of transparency has made the blockchain technology so popular among the masses. But the real catch is due to the fact that blockchain is completely free & carries no additional or hidden expenses. Owing to no transaction cost, it relies on transmitting blocks from one node to another in a seamless, secure manner through verification using millions of blockchain servers around the globe; any distributed system can serve as a blockchain server. The verified blocks are then added to a chain, with its unique record & history, validated by every blockchain server involved. The popular cashless monetary operations & transactions to operate with virtually no cost.
Blockchain is a still blooming market & IT developers in Blockchain are in demand for building of Dapps/Decentralised applications using blockchain technology. Comprehensive knowledge in blockchain programming is required, along with specializations in decentralized blockchain, dApp development, smart contracts, or cryptocurrency. Demand is high in this domain, so employability is also very high for blockchain developers.
Apart from the above skills, a good understanding of the business domain is also required to understand the behind-the-scenes scenes of blockchain, since it is primarily a commercial tool. Solid programming knowledge in languages like C++, Solidity along with the understanding of data structures, cryptocurrency is also required. These skills are easy to obtain for anyone coming from a computer science background, so mastering blockchain technology should be easy enough for him/her.
People skilled in blockchain technology can find employment in various domains related to blockchain. Positions like Blockchain Web Designer, Blockchain Engineer, Blockchain System & Application developer & Blockchain Legal Consultant are commonly up for grab in multinational companies & with proper mastery over these topics, you can be hired.
