Blockchain gained notoriety in relation to cryptocurrencies like Bitcoin and the security it offers. However, it also provides security that has a number of additional uses. In a blockchain, data can only be added to, not deleted or changed. It produces numerous data segments that link together to form a “chain,” hence the name “blockchain.”

Blockchain is a very secure technology since current data cannot be changed or removed. Because blockchains are consensus-driven, no one person or entity can control the data. A third party is not required to supervise transactions.

The need for knowledgeable blockchain developers has grown as more industries adopt and use them. It calls for practical experience with programming languages, a working understanding of OOPS, databases (both flat and relational), data structures, networking, and web application development.
