With the arrival of the Conway era, the Cardano blockchain is being enriched with a significant set of features revolving around governance. Governance can be defined as the ability for ada holders to take part in various on-chain decisions as described in CIP-1694. These new features have brought a substantial set of changes, such as new script purposes, new centralized data like committee, and new transaction features. This documents describes which of those features are currently being supported by cooked-validators, and to which extent. Each of the following items describes a feature that is currently supported. The reader can assume that everything that is not directly mentioned here about Conway is not yet supported.
It is currently possible to describe proposal procedures and attach an arbitrary number of those in transaction skeletons. The balancing mechanism will take into account the required deposit for each of these procedures.
It is possible to issue proposal procedures with a request for changes in parameters. If a script witness is attached to this proposal (typically the constitution script), it will be ran against the proposal. All kinds of parameter changes are supported, except for the cost models, which contain too many values and are not even yet taken into account by the current constitution.
It is possible to issue proposal procedures with a request for treasury withdrawals. If a script witness is attached to this proposal (typically the constitution script), it will be ran against the proposal.
