Blockchain is a system for recording data that is difficult to alter or manipulate. It is a digital ledger of duplicated transactions that are distributed across a network of computer systems. Each block in the chain contains a variety of transactions, and every participant's ledger is updated with a record of each new transaction that occurs on the blockchain. The use of blockchain technology is becoming increasingly popular in various industries as a means of securing data due to its incorruptible nature.

Some of the sectors that have begun to implement blockchain in their day-to-day use cases include finance, supply chain management, healthcare, real estate, and voting systems. By using blockchain, these industries can ensure that their data is secure, transparent, and immutable, which can lead to greater efficiency, cost savings, and enhanced trust among stakeholders.
