Omni Blockchain Examination Syllabus, Spring, 2020

Subject: Blockchain Theory and Application
Organizer: Omni Committee on Examination

Chapter I. Objectives

There is one aim for this syllabus: to instruct relatively unsophisticated programmers/audiences to understand the background, basic theory, and application of blochchain technology, grasp fundamental concepts, technical processes, specifications and their applicable scenarios. After passing this examination, audiences shall become a specialist with ability to develop blockchain products and applications.

Total score of this examination is 600 points, with each of the following sections 100 scores.

Section 1. Knowledge base of Blockchain
Section 2. Bitcoin network and Omnilayer specification
Section 3. Smart contract, Ethereum and HyperLedger
Section 4. Lightning network, LND and OmniBOLT specification
Section 5. Security
Section 6. System Maintenance
