Chang Upgrade #2 overview
Intersect plays the role of coordinator, as a functional servant-leader on behalf of the community and delivery teams working on hard fork activity. The functional teams within Intersect will work with the various committees, working groups, and delivery teams, relaying information here on the knowledge base. Ultimately the date for the hard fork is directly influenced by the community, the relevant constitutional approval and required on-chain voting.
Chang Upgrade Release
The Chang upgrade will stagger the release of governance functionality, easing adoption and onboarding for those with new or additional roles in governance.
Chang Upgrade #1 will deploy governance features to Cardano and enter the technical bootstrapping phase as described in CIP-1694 Bootstrapping Phase. Chang Upgrade #1 was successfully completed on September 1st 2024.
Chang Upgrade #2 moves CIP-1694 out of technical bootstrapping phase and unlocks the final features of on-chain governance including DRep participation and all governance actions
Further information on CIP-1694 and the interim bootstrapping period is available.
Chang Upgrade #2 Events
Following Chang#1 the Cardano blockchain has entered into a bootstrapping phase of governance. Special provisions will apply in this initial bootstrap phase. Firstly, during the bootstrap phase, a vote from the constitutional committee is sufficient to change the protocol parameters. Secondly, during the bootstrap phase, a vote from the constitutional committee, together with a sufficient SPO vote, is sufficient to initiate a hard fork - in this case Chang#2.
This is different to all previous hard forks or upgrades, where founding entities ultimately made the final decisions.
Governance Actions
The Chang upgrade #2 requires five (5) governance actions to be successfully enacted on chain. In this bootstrap phase of governance the ICC and SPOs will be required to vote on these accordingly.
Intersect will raise the required governance actions, as per the recommendations provided by parameters sub-committee for Plutus parameter updates and civics committee for Chang upgrade #2, ultimately moving Cardano out of bootstrap into full governance as defined by CIP-1694.
Plutus Parameter Updates:
The Governance Action for Mainnet parameter changes could earliest occur from epoch 517
The Governance Action for Pre-Production parameter changes could earliest occur from epoch 173
Chang Upgrade #2:
The governance action for Mainnet hard fork could earliest occur from epoch 520
Governance action for Prep-production could earliest occur from epoch 177
Governance action for preview could earliest occur from epoch 736
The governance actions should follow environment order, preview before pre-production and pre-production before Mainnet. Governance actions could overlap and be raised in parallel, this is to ensure smooth transition between upgrades in environments, particularly between pre-production and Mainnet.
Should the governance actions not occur at the earliest anticipated epoch they roll into the next. The governance actions will remain for 6 epochs before expiry, after this time they will need to be re-submitted.
