Radix uses a specific kind of staking as part of its Delegated Proof of Stake (DPoS) Sybil protection mechanism. Radix’s DPoS system weights validator consensus votes by the number of XRD staked to each validator node and decides which validators are included in the validator set for each epoch.
Because of this, XRD token holders play a critical role in securing the Radix Public Network.
Stakers are rewarded for supporting network security through DPoS with newly created XRD tokens over time. These newly created XRD tokens are called network emissions.
Selecting which validators to stake to is perhaps the most important role of any XRD token holder.
