When staking EGLD, users, also called "delegators", deposit at least 1 EGLD token with a staking provider, also called a "validator", and thus make a valuable contribution to securing and decentralizing the MultiversX blockchain. In return, delegators receive rewards in the form of EGLD. An usual delegator reward or return, called "APR" (annual percentage rate), varies between 9% to 12%.
In order to operate a node (a server/computer in the network) in the MultiversX blockchain as a validator, the validator must deposit a minimum of 2,500 EGLD. Validating transactions will also be rewarded in the form of EGLD and every validator chooses his/her own reward (also called a "service fee").
