Description

Introduction of Blockchain Networks

This course explores the concept of blockchain interoperability, focusing on how various blockchain networks communicate and collaborate to share data, assets, and services seamlessly. Participants will gain insights into cross-chain protocols, interoperability frameworks, and the technical and governance challenges associated with connecting multiple blockchains. Real-world use cases will demonstrate how interoperability boosts blockchain adoption by enhancing scalability and enabling more complex decentralized applications (DApps).

Prerequisites

• Basic Knowledge of Blockchain Networks (Ethereum, Bitcoin, or Polkadot)
• Familiarity with Smart Contracts (Solidity or similar languages)
• Understanding of Decentralized Finance (DeFi)
• Basic Networking Concepts (Protocols, APIs, and Cryptographic Keys)
