Getting Started

A detailed set of installation and usage instructions as well as breakdowns of each individual component are available in the official documentation portal. If you still have questions, feel free to stop by our Discord.

Staking on Mainnet

To participate in staking, you can join the official eth2 launchpad. The launchpad is the only recommended way to become a validator on mainnet. You can explore validator rewards/penalties via Bitfly’s block explorer:, and follow the latest blocks added to the chain on beaconscan.



Prysm maintains two permanent branches:

  • master: This points to the latest stable release. It is ideal for most users.
  • develop: This is used for development, it contains the latest PRs. Developers should base their PRs on this branch.
