Blockchain technology is an open, decentralized peer-to-peer network technology. It uses a public ledger which consents two parties to reach common ground of info without allowing full access to anyone.

Basically, a blockchain is an open decentralized database file for storing data or information.


The file is made up of blocks of data, and each block is linked to another block, forming a chain. Each block holds data (such as transaction data) and a record of when that block was edited or created. Unlike a centralized database that’s owned by a corporation or agency, a blockchain isn’t controlled by anybody person or entity. The info is duplicated (distributed) in its entirety across many computers, meaning any user can view the whole chain from anywhere, and anyone with the proper cryptography keys can edit the chain. As it is a decentralized way of storing and accessing data. It makes blockchains extremely protected because, unlike a centralized database, there’s no single point of entry for attackers. This makes it particularly convenient for recording transactions in a secure manner.


Blockchain technology is being used in a lot of sectors nowadays. In the near future, the use of blockchain technology in everyday life would be increase significantly. Let us know about 5 top use cases for blockchain technology and its possible implementations in the near future:
