Ethereum Developer Blockchain Training

The Ethereum Developer Blockchain Training course is a 3-day course that is designed to provide students with an in-depth understanding and development experience with the Ethereum Blockchain platform. Students will receive an overview of Ethereum, smart contracts, and the development language, Solidity. Studetns will write smart contracts and build applications that interact with them.

Ethereum's adaptable feature set which allows developers to design decentralized applications for countless applications will be covered. Students will participate in hands-on programming lab sessions so that they can develop and advance their skills in Ethereum development.

Approximately 50% of class will be lab time. This provides practical experience, which will enhance the student's knowledge and existing skill set.
