Blockchain Technology Explained

At its heart, a blockchain is a distributed, immutable ledger. It's a chain of "blocks," where each block contains a list of transactions. Each block is cryptographically linked to the previous one, forming a secure and tamper-evident chain. This ledger isn't stored in a single location; instead, it's distributed across a network of computers, making it decentralized and resilient to single points of failure.

While most famously known as the technology underpinning cryptocurrencies like Bitcoin, blockchain's potential extends far beyond digital money. It can be used to create transparent and secure systems for supply chain management, voting systems, digital identity verification, and smart contracts—self-executing contracts with the terms of the agreement directly written into code. Its ability to facilitate trust in a trustless environment is its most revolutionary feature.
