Staking is the process of locking up your assets (in this case INJ) in order to validate transactions on the blockchain. Users who stake their assets are usually eligible for staking rewards.Injective follows a proof-of-stake mechanism, in which users can stake their INJ tokens with certain Injective nodes that validate transactions (validators). In return, the user can obtain staking rewards in INJ.
Rewards start accruing the moment you stake INJ. Monitor your rewards in the staking section of Injective Hub. Once you have earned a sufficient amount of rewards, you may withdraw them at any time.
