The Certified Blockchain Developer - Ethereum (CBDE) exam is an elite way to demonstrate your knowledge and skills in this emerging space. Additionally, you will become a member of a community of Blockchain leaders. With certification comes monthly industry updates via email and video.

The CBDE exam is a 70 question multiple-choice exam that lasts 1.5 hours and is performance-based evaluation of Ethereum Development skills and knowledge. Internet access is not provided during the exam, nor is any course material or study guides.

A person who holds this certification demonstrates their ability to:

• Plan and prepare production ready applications for the Ethereum blockchain
• Write, test, and deploy secure Solidity smart contracts
• Understand and work with Ethereum fees
• Work within the bounds and limitations of the Ethereum blockchain
• Use the essential tooling and systems needed to work with the Ethereum ecosystem

This exam will prove that a student completely understands how to:

• Implement web3.js
• Write and compile Solidity smart contracts
• Create secure smart contracts
• Deploy smart contracts both the live and test Ethereum networks
• Calculate Ethereum gas costs
• Unit test smart contracts
• Run an Ethereum node on development machines

Scores and Reporting

Official scores for exams come immediately following the exam from Pearson VUE. A passing score is 85% (60 questions answered correctly). Exam results are reported PASS/FAIL and you will be provided your percentage. Blockchain Training Alliance does not report scores on individual items, nor will it provide additional information upon request.
