Cardano’s Chang Hard Fork Paves Way for Voltaire Era with Node 9.1.0 Release

The Cardano network is on the cusp of a significant milestone with the imminent Chang hard fork, marking the onset of the Voltaire era.
This pivotal transition is supported by the latest node validator software release, version 9.1.0, which introduces critical updates essential for the hard fork.
Charles Hoskinson, Cardano’s founder, announced the update on X, stating, “This is it. End of the line, node 9.1 is Voltaire. Happy upgrading SPOs. Welcome to Chang.”

Cardano network approaches the Chang hard fork, ushering in the Voltaire era and enhancing on-chain governance with node version 9.1.0.

Cardano Chang Hard Fork Is Ready

The upgrade from node version 9.0.0 to 9.1.0 is a significant development as it incorporates the crucial Conway genesis file at startup, a mandatory change necessary for the Chang hard fork transition. Previously, this file was optional, marking a notable shift in the network’s startup protocol.

Technical Enhancements and Integrations

In addition to the genesis file integration, version 9.1.0 includes several bug fixes and enhancements to both the command-line interface (CLI) and the application programming interface (API). Notably, the new “query treasury” command offers improved insights into the network’s financial operations. Updates also ensure compatibility with Cardano Improvement Proposals CIP69 and CIP119, which standardize metadata structures and introduce a transaction metadata label for streamlined processing.

Community-Driven Activation

As outlined by Intersect, a key organization within the ADA ecosystem, the community will determine the timing for the Chang hard fork’s activation. This major fork will proceed once 70% of validators adopt the new node, emphasizing a community-first approach. The Chang hard fork represents a significant advancement for Cardano, moving from the Vasil upgrade to a foundation where on-chain governance driven by the community becomes a reality through the implementation of CIP-1694 mechanisms.

Features and Phases of the Chang Upgrade

The Chang upgrade introduces a robust framework for decentralized decision-making, where ADA holders participate directly through on-chain consensus. Delegate Representatives (DReps) will be crucial in voicing community interests and guiding the network’s future. The upgrade will be executed in two distinct phases. Chang Upgrade #1 focuses on the deployment of initial governance features, marking the start of the technical bootstrapping phase as described in CIP-1694. Subsequently, Chang Upgrade #2 will transition these governance mechanisms out of the bootstrapping phase, enabling comprehensive on-chain governance, including DRep participation.

Honoring Phil Chang

This upgrade also serves as a tribute to Phil Chang, a pivotal figure in Cardano’s governance strategies at IOG, who passed away in 2022. His contributions have been instrumental to the Voltaire era’s concept, which the Chang upgrade aims to actualize.

Conclusion

The Cardano network is poised for a transformative phase with the impending Chang hard fork and the introduction of the Voltaire era. By enabling decentralized governance and community participation, this upgrade promises to enhance the network’s robustness and future prospects. The inclusion of technical enhancements and comprehensive on-chain mechanisms marks a significant step forward for Cardano.
