Blockchain is one of the hottest technologies in the skill market for the last few years. In 2019, blockchain professionals were at the top of the list of most in-demand jobs, as per LinkedIn. A great number of banking, insurance, and technology companies have been utilising various blockchain solutions. The blockchain ecosystem has been flourishing in places like Europe and South Asian countries with new-age banking services and advancing decentralised innovation in the financial sector, known as Decentralised Finance (DeFi).
Because the technology is still very nascent, people with varied technical backgrounds and coding skills have got on the bandwagon and built a career by understanding the technical aspects in detail and finding an area where they can contribute, be it open-source software, blockchain architecture, and working on new protocols.
Blockchain is based on technology application, and its true value is in bringing trust and fairness to applications. Blockchain technology uses hash functions and Merkel trees as the basic data structure. Through a distributed consensus protocol that is not controlled by any individual, an immutable and traceable data structure is established. Due to the protection of cryptography technology, no organization, any individual, or any machine has the ability to tamper and smear the data in the blockchain at the current technical level.
