Hard Fork Frequently Asked Questions

This FAQ will be updated intermittently by the hard fork working group, answers are subject to change for additional clarity, as this becomes available

The hard fork working group has collated key questions and formed the following frequently asked questions (FAQ) for the benefit of the community.


Questions on the general Chang hard fork

What improvements can users expect from this upgrade?

The Chang hard fork will introduce significant enhancements to the Cardano ecosystem, introducing a new era of decentralized governance. Chang brings the first step in Cardano’s era of Voltaire, with the deployment of the CIP-1694 governance model. Further included is Plutus V3, which brings a host of enhancements and new built-ins for smart contract developers.

What happens if I do not update my node software for the Chang hard fork?

If you do not update your node software to align with the Chang hard fork, your node will become incompatible with the updated blockchain. This may result in your node being unable to process transactions or interact correctly with the updated network.

What is the general state of ecosystem readiness for all of these changes? What is the potential impact if a particular wallet, dApp, etc., isn’t explicitly updated?

The ecosystem must update to the latest protocol version (9.0) to ensure compatibility. Previous versions may cease to function properly, and fee calculations may fail, leading to potential disruptions in services. Of course there is no potential danger of loss of funds.

Where can users find the latest information about the Chang hard fork?

The community can find the latest information on the Chang hard fork on Intersects website and knowledge base, community forums, and through updates posted on official Twitter, Discord channels. Intersect also provides newsletters and developer updates that you can subscribe to for the latest news.

Are there any expected downtimes or maintenance periods associated with the Chang hard fork?

No, the network is expected to remain completely operational through the hard fork, although users are warned that tooling they use may require maintenance.

How does the upcoming Chang hard fork differ from Vasil - the last hard fork?

The Chang Hard Fork on the Cardano network marks a significant advancement from the previous Vasil upgrade, focusing on more comprehensive range of improvement:

  • Community Driven Governance - Introduces a governance model that allows ADA holders to participate directly in decision making processes through on chain consensus.

  • Delegate Representatives (DReps) - Plays a crucial role in representing community interests and influencing the network’s future direction.

  • Constitution Convention - An event where stakeholders draft a guiding framework for network governance and community interaction.

  • Community Vote on Constitution - Engages the broader community in voting on the drafted constitution, emphasizing Cardano’s commitment to decentralized governance.

This update signifies Cardano’s transition into the Voltaire era, focusing on scalability, security, and community governance, setting the stage for further innovations and broader adoption.

What preparations are involved in the Chang hard fork?

Preparations for the Chang hard fork include the creation of a detailed Genesis file which will include the Constitution, governance policy scripts, the interim constitutional committee, and all initial settings for governance parameters. This Genesis file is crucial and will be reviewed thoroughly before it is finalized and implemented.


Questions on the Conway Era

Have the changes to the ledger and protocol for the Conway era been finalized, can people add support for them at this point without something possibly changing later on?

Yes, the changes have been finalized with the exception of any impacts from testing results. Adjustments may be necessary if testing identifies the need for changes.


Questions on Testing

How will the Chang hard fork be previewed and tested before full deployment?

Node 9.0 will be previewed and tested concurrently with the pre-production network. This process is controlled by the community, ensuring thorough testing and validation before the full deployment. The preview and pre-production are expected to follow the same governance rules as the mainnet, ensuring consistency across environments.

How does the community involvement in testing work?

Community testing is conducted on SanchoNet as well as other test networks, where various elements including governance policies and committee scripts can be tested. This stage allows for community feedback and is essential for ensuring the robustness of the hard fork. Community members can participate in this testing by engaging with the latest node versions available on SanchoNet.


Questions relating to Governance, Voltaire, and the Roadmap

How does the Voltaire Era influence the Chang Hard Fork in terms of governance?

The Voltaire Era is a critical and final phase in Cardano’s evolution, introducing robust community-driven governance mechanisms. This era enables ADA holders to vote on network upgrades and funding proposals through a decentralized governance system. The Chang Hard Fork can be seen as a technical step that supports the principles of the Voltaire Era by enhancing the blockchain’s capabilities, thus preparing it for more sophisticated governance functions that the Voltaire Era aims to implement.

What governance features introduced in the Voltaire Era will be utilized or expanded in the Chang Hard Fork?

The Chang Hard Fork will introduce on-chain governance to Cardano.

What are some key milestones to watch out for in Cardano’s roadmap for 2024?

In addition to the Chang Hard Fork, Cardano’s roadmap for 2024 includes significant milestones such as the Cardano Constitution Workshops, Intersect Growth initiative, and advancements in real-world asset tokenization. These developments are poised to reshape the landscape of decentralized finance and blockchain technology.


Questions on how to get involved and how to prepare

How will changes and updates be communicated to the community?

Updates and significant changes will be communicated through various channels including Twitter, Discord, community forums, and the project’s knowledge base. Important updates will also be discussed in follow-up meetings, ensuring all stakeholders have the latest information and can provide feedback.

What role does community governance play in the Cardano upgrade roadmap?

Community governance is a central aspect of Cardano’s upgrade roadmap. Through initiatives like the Cardano Constitution Workshops and Delegate Representatives (DReps), the community actively participates in decision-making processes, shaping the future direction of the network.

What steps should users take to prepare for the hard fork?

Here’s what users can do to prepare:

  • Stay informed - Follow official Cardano and intersect channels for announcements and updates regarding the hard fork.

  • Update wallets and applications - Ensure you’re using the latest versions of Cardano wallets and applications to guarantee compatibility with the new protocol.

  • Take part in SanchoNet testing - It is a specialized test network to comprehensively implement and test the tools for the self-governance of the Cardano blockchain.
