We recommend staking with a Ledger Nano S and Lunie.io.

About Validators

The role of validators is to run a full-node and participate in consensus by broadcasting votes which contain cryptographic signatures signed by their private key.
Validators commit new blocks in the blockchain and receive revenue in exchange for their work.
They must also participate in governance by voting on proposals. Validators are weighted according to their total stake.

About Staking

The Cosmos Hub is a public Proof-Of-Stake (PoS) blockchain, meaning that the weight of validators is determined by the amount of staking tokens (Atoms) bonded as collateral.
These Atoms can be seld-delegated directly by the validator or delegated to them by other Atom holders.
Any user in the system can declare their intention to become a validator by sending a create-validator transaction. From there, they become validator candidates.
The weight (i.e. voting power) of a validator determines whether or not they are an active validator. Initially, only the top 100 validators with the most voting power will be active validators.

Don't Forget to Stake!
