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, Cardano's governance was governed by the Cardano Foundation, Input Output Global (IOHK) and Emurgo.
