Cardano Blockchain is headed for the “Chang Hard Fork”, the biggest update in two years

CIP-1694 is the Cardano Improvement Proposal at the heart of the update, which introduces various governance structures to the Cardano ecosystem, including the Constitutional Committee, dReps and Stake Pool Operators (SPOs). Once CIP-1694 is implemented, the Cardano blockchain and any changes to it will be in the hands of these groups.
