Introduction

​

​

Decisions on Cardano parameters are currently made by the Protocol Parameter Policy Committee within IOG. However, there is a need to expand the committee outside IOG by including a selection of community members in order to begin to fulfill one of the pillars of the Voltaire era, which is community involvement in the governance and oversight of the Cardano Ecosystem.

Once the MBO is set up, stewardship of this committee will transition to the MBO

In the following slides you will find the committee’s intermediate state structure before MBO creation.

Parameter Committee | Responsibilities (slide 1 of 2)

Approve or reject proposals

Monitor progress and performance

​

Provide technical expertise in a specified topic

Make recommen-

dations in the best interest of Cardano

The committee may consider, recommend and make a decisions on proposals submitted by community members or stakeholders regarding a specific issue, or changes to a parameter related to either an economic policy change or a strategic decision affecting the operation of the network. In the future, CIP implementation will be part of the discussions.

The committee should monitor and evaluate the progress of an approved project or initiative, make decisions to address challenges and propose new changes.

Advisors should be domain experts in one or more technical areas of Cardano and should keep that expertise up to date by staying informed of latest developments.

Regardless of affiliation to a particular interest group or employer, advisors & key holders, are expected to make recommendations, assess impact, risks and determine priority of change requests (CRs), in the best long term interest of the Cardano protocol.
