Staking Basics

Aleph Zero is a PoS (Proof of Stake) blockchain, and as such, it uses staking as a mechanism to keep the platform safe and stable. More specifically, there are two special roles in Aleph Zero requiring users to stake their tokens:
  • Validators: these are users that run Aleph Zero nodes. They process transactions, validate blocks, and take part in the AlephBFT consensus to finalize blocks, thus making them irreversible. To become a validator, one must stake enough AZERO and also have technical skills to run the Aleph Zero node software. If you want to become a validator, we refer to the validator guide for more details about validator staking. Users who contribute to the well-being of the chain as validators are rewarded for their service with AZERO; for more details see staking rewards.
  • Nominators: these users don't run Aleph Zero nodes but still want to contribute to the network's security and earn staking rewards. Towards this end, they nominate their stake to some trustworthy validators. This way, a nominator's stake is allocated to a particular validator, who then has proportionally higher vote power in the consensus and earns more rewards. See staking rewards for more details on how validators and nominators are rewarded for staking.
Since validating requires certain technical expertise, most users contribute by becoming nominators. If you would like how to do that, please visit the How to Start Staking section.
