In this article, we’ll walk you through a simple, actionable guide to begin your blockchain journey. Whether you’re a complete beginner or just looking for a clear starting point, this guide will help you dive into the world of blockchain with confidence.
What is Blockchain? At its core, a blockchain is a digital ledger—a secure and transparent way to record transactions. Imagine a spreadsheet that’s duplicated across a network of computers, where every addition or change is verified by consensus. This decentralized system ensures that no single entity controls the data, making it tamper-proof and highly secure.
At the heart of blockchain technology lies the block, a digital container that stores information about transactions. Think of it as a page in a ledger, recording details like:
• The sender and receiver of a transaction.
• The amount or value being transferred.
• A unique identifier called a hash, which secures and links it to other blocks.
In this guide, we’ll explain the two most prominent consensus mechanisms—Proof of Work (PoW) and Proof of Stake (PoS)—their differences, and why they matter in the blockchain world.
A consensus mechanism is the process by which a blockchain network agrees on the validity of transactions.
