Certified Blockchain Ethereum Developer (CBED)

About Certification

GSDC's Global Accreditiated Certified Blockchain Ethereum Developer program validates candidates knowledgeable about the Ethereum blockchain, Ethereum transactions, the Solidity programming language and how to use it to write smart contracts on the Ethereum network.

This certification course is designed for programmers and developers who want to take a comprehensive deep dive in writing smart contracts and building applications that interact with them. By completing the program, participants will be able to code their own smart contracts on the Ethereum network; while also exploring the theory behind Tokens, ICO's, DAO's, and many more exciting new industry standard approaches to Blockchain Development.



  1. Plan and prepare production ready applications for the Ethereum blockchain.
  2. Code an Ethereum Blockchain.
  3. Write, test, and deploy secure Solidity smart contracts.
  4. Understand and work with Ethereum fees.
  5. Work within the bounds and limitations of the Ethereum blockchain.
  6. Use the essential tooling and systems needed to work with the Ethereum ecosystem.
