Description

Introduction

Blockchain technology has transformed how we think about data, trust, and transactions, paving the way for decentralized applications (dApps) that operate independently of traditional intermediaries. In this training, participants will learn how to build dApps that leverage blockchain’s decentralized nature, providing greater transparency, security, and efficiency. From understanding smart contracts to deploying your own decentralized application, this course offers hands-on experience to take your blockchain skills to the next level.

Prerequisites

• Basic understanding of programming: Knowledge of at least one programming language, such as JavaScript or Python.
• Familiarity with blockchain concepts: Prior exposure to blockchain fundamentals such as cryptocurrencies, decentralized networks, and blockchain architecture.
• Understanding of web development: Experience with web development (HTML, CSS, JavaScript) is beneficial.
• Introduction to smart contracts: Some knowledge of smart contracts and platforms like Ethereum is a plus.
