Introduction
Blockchain technology has emerged as one of the most transformative innovations of the 21st century. Initially developed to support Bitcoin transactions, blockchain has evolved beyond cryptocurrency and is now reshaping various industries. In simple terms, a blockchain is a decentralized digital ledger that records transactions across multiple computers, making it secure, transparent, and tamper-proof.
This blog explores how blockchain works and highlights real-life applications that showcase its potential across industries.
How Blockchain Works
At its core, blockchain is a chain of digital blocks containing transaction records. Each block is linked to the previous one using cryptographic hashes, ensuring security and immutability. Key features include:
- Decentralization: No single entity controls the data; instead, it is distributed across multiple nodes.
- Transparency: Transactions are visible to all participants, enhancing trust.
- Immutability: Once recorded, data cannot be altered, preventing fraud.
- Smart Contracts: Automated agreements that execute when predefined conditions are met.
