Certified Hedera Hashgraph Developer

Become a Certified Hedera Hashgraph Developer

Hedera is a fully open source, proof-of-stake, public network and governing body for building and deploying decentralized applications. It offers developers three primary services: Solidity-based smart contracts, consensus, and token services. Hedera is unique in that it is incredibly fast, energy-efficient (carbon negative), and secure — these advantages can be attributed to its underlying hashgraph consensus algorithm.  The Certified Hedera Hashgraph Developer (CHHD) program allows candidates to demonstrate the knowledge to develop and maintain client applications using the latest Hedera programming model. This course also introduces you to the Smart Contracts service, which runs the EVM (Ethereum Virtual Machine).

Student Outcomes

  • Hedera Hashgraph Developer – Certificate of Completion
  • CERTIFICATION: Certified Hedera Hashgraph Developer (CHHD) from the Blockchain Certification Association (BCA)

About the CHHD Certification & Exam

This two-hour AI-Proctored high-integrity exam accomplished remotely consists of 50 randomized questions out of a text bank of 75 questions. A passing score of 75% or greater will result in a digital credential stored on-chain to validate your knowledge and ability. You will have two exam attempts, with no additional charge for the second exam attempt. A third exam attempt will cost $ 150 USD.

While not required to sit for the CHHD exam, this course provides developers with all the information needed to pass the exam successfully. Students are provided quizzes throughout the course to validate the material covered. The final exam within this course serves as exam prep for the Certification exam. Regardless of whether or not you sit for and pass the CHHD Exam, you will receive a Certificate of Completion should you achieve 70% or better on the final course exam.

What it Demonstrates

A CHHD demonstrates the knowledge to develop and maintain client applications and smart contracts. A CHHD certification demonstrates the skills and expertise to build and maintain Hedera applications and Smart Contracts using the latest Hedera programming APIs and development model. A developer must also be able to:

  • Configure a development environment with the Hedera APIs and Software Development kits (SDKs).
  • Develop and build Hedera applications using the Hedera SDKs and perform end-to-end application life-cycle, i.e., build and test applications.
  • Program in Java, JavaScript and other Hedera SDK programming languages.
  • An introduction to the Hedera Smart Contract Service is also including with an introduction to the Solidity programming language for Smart Contract development is the EVM.

Passing a high integrity exam demonstrates the candidate’s ability to perform challenging real-world tasks under time constraints and your Hedera skills and knowledge.
