Certified Blockchain Ethereum Developer (CBED)

About Certification

GSDC's Global Accreditiated Certified Blockchain Ethereum Developer (CBED) program validates the candidate's knowledge about the Ethereum blockchain, Ethereum transactions, the Solidity programming language.

This certification is designed for programmers and developers who want to take a comprehensive deep dive into writing smart contracts in the Ethereum network and building applications that interact with them. After completion of this program, participants will be able to code their own smart contracts while exploring the theories behind Tokens, ICO's, DAO's, and many more brand new approaches to Blockchain Development.



The main objective of this certification is empowering the participants in:

  1. Planning and preparing production-ready applications for the Ethereum blockchain.
  2. Coding Ethereum Blockchains on their own.
  3. Writing, testing, and deploying secure Solidity smart contracts.
  4. Understanding and working with Ethereum fees.
  5. Working within the bounds and limitations of the Ethereum blockchain.
  6. Usage of the essential tools and systems which are needed to work with the Ethereum ecosystem.
