What is Prysm?
The Prysm project is a full-featured client for the Ethereum 2.0 network written entirely in the Go programming language. Created by Prysmatic Labs, Prysm implements the official Ethereum 2.0 specification, which is the product of an ongoing collective research and development effort by various teams across the Ethereum ecosystem including the Ethereum Foundation.
This manual is aimed at developers interested in participating in Ethereum 2.0's public test network known as the Medalla testnet and reviews the concepts behind the changes made in Ethereum 2.0, as well as the core components of the Prysm client itself. For more detailed information on the most recent research developments and understanding what Ethereum 2.0 is, it is recommended to review Eth2Info and the official Ethereum 'Serenity' 2.0 specification repository.
