• Blockchain technology has revolutionized the field and captured the attention of corporations across different fields, which is possible only because of its incredible features and possible applications. Fundamentally expressed, blockchain is a distributed database, that records all occurrences or transactions both digital and decentralized through the participating parties. This technology has its merits, e.g., it allows participants to be involved from all around the world, security is provided by cryptography, the transparency of the whole process, quick transactions can be done, and the parties in the transaction can be trusted. Simply, blockchain technology has some difficulties such as scalability, energy overuse, technical complexity that hinders adoption, regulation is blurred, and there is no standard approach or technology. The working principle of blockchain technology consists of the creation of a tamper-proof distributed ledger where the transactions are recorded in a way they cannot be altered. The validity of each transaction is verified by the participants in the majority of the system, wherein the data is protected from any malicious attacks. The built-in characteristics of blockchain, with data being distributed over millions of computers, make it possible to notarize data and make the process public. The nodes, which are computers tied to the blockchain network perform the equally important tasks of verifying transactions and propagating them, hence they correctly execute safe and transparent transactions.

• The workings of blockchain are pretty simple and easy to understand. In simple terms, it is a growing list of records known as blocks, which are linked using cryptography. Each block is linked to a previous block using a digital signature. This time-stamped series of blocks forms a ledger; a decentralized database that is managed by a network of contributors. This is a record of transactions, all the previous records of transactions are named as the blocks. Thus, the blockchain is a distributed ledger that keeps track of all the transactions made. These transactions can be any movement of goods, money, or even data. Now, every piece of data in a blockchain is grouped into a block. Now these blocks are limited to a certain storage capacity and once that limit is reached, a new block is created. There is a connection between each block that gets created, it is like a link in a chain, hence the name blockchain.
