A Yellow Paper is a technical document that outlines the technical specifications and design of a particular cryptocurrency or blockchain system.
The contents of a Yellow Paper may include:
- detailed information about the algorithm

Yellow Paper is often less formal than White Paper. The term "Yellow Paper" seems to have originated from the color of the paper used for the Ethereum project to publish its technical specifications in 2014.
The purpose of a Yellow Paper is to provide developers and interested parties with a deep understanding of the technical workings of a particular cryptocurrency or blockchain system.
