Introduction
When people hear the word blockchain, they often think of cryptocurrency. While digital currencies like Bitcoin and Ethereum introduced the technology to the world, blockchain has grown into something far greater. Today, it is being used across industries for security, transparency, and efficiency.
What is Blockchain?
Blockchain is a digital ledger system that records transactions across multiple computers in a secure and tamper-proof way. Each block of data is linked to the previous one, making it nearly impossible to alter without detection. This design creates trust in systems that require accuracy and transparency.
