Yes, we encourage all XRD holders to stake their XRD to good validator nodes as greater stake provides greater protection for the network against Sybil attacks – and so Radix Foundation (and its subsidiaries) intend to stake tokens for the same reason.
A portion of these tokens will be delegated to nodes operated by Radix Token (Jersey) Limited, which may, as a result, be selected as part of the validator set.
The Radix Foundation and any subsidiaries aim to stake a total quantity of XRD to Radix-operated nodes that is no more than 25% of the total XRD staked at any given time. This is well short of the 33.3% threshold which would confer the ability to disrupt the network (even by accident) and make clear that control of the network always belongs in the hands of a decentralized community.
Any staking above the 25% level is intended to be distributed across the broadest possible selection of validator nodes that we believe are trustworthy and performant.
