The Cardano blockchain is about to undergo the biggest upgrade in two years, the "Chang Hard Fork", whose main function is to introduce an on-chain governance mechanism. Users holding ADA will be able to elect representatives (dReps) and vote on improvement proposals and future technical changes. The upgrade was originally scheduled for this week, but it has been postponed to September 1 because some exchanges need time to prepare the system. The Chang hard fork is part of Cardano's "Voltaire Era" and aims to achieve a self-sustaining blockchain system managed by the community. The upgrade also includes the core improvement proposal CIP-1694, which will strengthen the community's control over the network through governance structures such as the Constitutional Committee, dReps, and staking pool operators.
