How Does Blockchain Work?

Blockchain operates by creating blocks of information that are stored across a decentralized computer network, forming a ledger. Every ledger in the network keeps track of all the changes and transactions made on that blockchain. This creates a secure and unchangeable database. The security offered by blockchain has paved the way for decentralized finance, also known as DeFi. 

DeFi is a financial system built on blockchain technology that aims to eliminate intermediaries like banks and enable direct peer-to-peer transactions. It provides opportunities for borrowing, lending, trading, and other financial activities without relying on traditional institutions. DeFi is gaining popularity due to its potential for increased financial accessibility, transparency, and autonomy.
