This Cardano Constitution is proposed to replace the Interim Constitution. The Cardano Constitution is the result of extensive Cardano community consultation throughout 2024. The Interim Constitution was intended to be temporary, and its Appendix II: Ratification of Final Constitution required its replacement to be submitted on-chain no later than January 31, 2025.

We propose to upgrade Cardano mainnet to Protocol Version 10. This upgrade will be achieved via a Hard Fork (called "Plomin"). Following the upgrade: 1. The Cardano mainnet protocol will be upgraded to Major Version 10 and Minor Version 0; 2. All 7 governance actions that are described in CIP-1694 will be enabled; 3. DRep voting will be enabled on all 7 governance actions; 4. SPO voting will be enabled on all applicable governance actions, as defined in CIP-1694; 5. Constitutional Committee voting will be enabled on all applicable governance actions, also as defined in CIP-1694; 6. Staking rewards can be accumulated as usual, but can only be withdrawn following delegation to a DRep (including the pre-defined abstain/no-confidence options); 7. Several new Plutus primitives will be available. In line with the Interim Cardano Constitution: 1. More than 90 days will have elapsed from the date of the Chang hard fork before ratification of this governance action; 2. At least 85% of stake pools by stake should have upgraded to a version of the node that can support protocol version 10 before ratification of this governance action. These conditions will be verified by the Interim Constitutional Committee and SPOs, supported by readiness reports from Intersect's Hard Fork Working Group.
