Description
Introduction of Ethereum & Smart Contracts
Ethereum has revolutionized the blockchain space by enabling decentralized applications (dApps) through smart contracts—self-executing contracts with predefined conditions. This introductory course is designed to provide participants with a fundamental understanding of Ethereum, its blockchain architecture, and smart contracts. Whether you are a developer or simply interested in the technology, this training will equip you with the necessary tools and knowledge to create and deploy basic smart contracts on Ethereum.
Prerequisites:
- Basic programming knowledge (e.g., Python or JavaScript)
- Interest in blockchain technology
- Familiarity with web technologies (helpful but not required)
