On January 30, Cardano successfully activated the "Plomin" hard fork upgrade on Wednesday, which allows ADA token holders to participate in Cardano's future decisions, including voting on treasury measures and hard forks. The core change of this upgrade is the full introduction of Delegate Representatives (dReps), who will vote on governance issues on behalf of ADA token holders. Previously, the governance of Cardano was handled by the three founding entities of Cardano Foundation, Input Output Global (IOHK), and Emurgo, but these responsibilities have now been transferred to the new Cardano governance team. Before Plomin goes live, staking pool operators need to upgrade nodes and approve the upgrade with 51% of votes. As of this week, about 85% of nodes have switched to the new version.
