RADIX token (XRD) is the native token of the Radix Public Network, used for staking to secure the network through Delegated Proof of Stake (DPoS) and paying for transaction fees. XRD holders can vote on validator nodes by delegating tokens to them and earn network emission rewards. The top 100 validators with the most delegated stake are selected as the validator set, but this limit is expected to be removed in the future. Transaction fees are paid in XRD, and 100% of the fees are burnt by the Radix Protocol to prevent spam transactions across the network.
