Understanding Blockchain Development

What is Blockchain? Blockchain Architecture Explained

Blockchain is a decentralised computer network ledger that keeps track of transactions. 

Unlike traditional databases, a blockchain is inherently secure, transparent, and immutable due to its unique architecture. 

Each block in a blockchain contains a list of transactions and is linked to the previous block, forming a chain. 

This structure ensures that once data is recorded, it cannot be altered without altering all subsequent blocks, which requires the consensus of the network.

Blockchain Development Guide: An Overview

Blockchain development involves creating and managing blockchain-based applications, also known as decentralized applications (dApps).

These applications run on a blockchain network and are powered by smart contracts—self-executing contracts with the terms of the agreement directly written into code. 

To begin blockchain development, developers need a strong understanding of blockchain architecture, programming languages, and the various development tools available.
