[Unichain White Paper: Node operators need to stake UNI tokens on the Ethereum mainnet to become UVN validators] On October 10, the Unichain white paper pointed out that to become a validator in UVN (Unichain Virtual Machine), node operators must stake UNI tokens on the Ethereum mainnet. Participants can also stake and vote for validators, thereby increasing the stake weight of the validator. A limited number of validators with the highest stake weight will be considered an active set and will be eligible to publish proofs and receive designated rewards for that Epochs.
