Blockchain, as the name suggests, is a chain of blocks that are linked together using cryptography. These blocks contain data (such as transaction data, medical reports, documents, etc.), a timestamp denoting the time the block was created, and a cryptographic hash of the previous block. This links the blocks to one another in a linear fashion. The blocks once created are immutable and the data inside them cannot be changed. Thus, the blockchain transactions are transparent and visible to all. Development in the industry has led to a viable career in blockchain.
Blockchain doesn’t run on a single server but it runs on a network of individual or group of computers which makes the Blockchain technology decentralized. Being decentralized makes it transparent as well as secure. Each block in the chain has its hash along with the hash of the previous block. If a hacker tries to make changes to one of the blocks, it would be identified as illegitimate after comparing it to other blocks in the chain.
