These are the minutes of the PCs (Parameter Committee) triweekly meeting. This is a summary based on automatically generated notes and may therefore contain inaccuracies or errors.
The purpose of the Parameter Committee is to provide technical advice and recommendations relating to protocol parameters. It discusses all parameters relating to the Cardano protocol including network, technical, economic and governance parameters.
Summary
Kevin Hammond confirmed that the intent to change parameters, fulfilling PCP 003 and 004, was posted on the forum, initiating a three-month notification period, and he and Alexander Moser discussed the lack of a ledger economics expert on the parameter committee and the need for a second vice chair. Markus Gufler provided statistics indicating the chain is not heavily loaded, and he and Alexander Moser discussed that increasing the max block size could positively impact adoption.
Details
- Parameter Committee Proposals (PCPs) Alexander Moser confirmed that the intent to change parameters, fulfilling PCP 003 and 004, was posted on the forum by Kevin Hammond, initiating a three-month notification period. Kevin Hammond clarified that PCP 003 relates to increasing memory limits, while PCP 004 concerns the Plutus cost model. They discussed whether to process both PCPs together, agreeing that waiting three months for PCP 004 due to treasure withdrawals is acceptable, as it allows time for the situation to settle.
- Ledger Economics Expertise Alexander Moser raised the issue of the parameter committee lacking a subject matter expert on ledger economics, mentioning that they have reached out to the TSC for suggestions. Kevin Hammond emphasized the need to boost expert knowledge and suggested that the TSC could ask for additional volunteers with expertise in this area. They discussed potential candidates like Masimo, who is already part of the working group, and the general weakness in Cardano regarding economic expertise.
- Second Vice Chair Position Alexander Moser announced that VJ had left the committee and raised the question of whether a second vice chair replacement was needed, suggesting that it might not be necessary given the current structure. Tommy Kammerer inquired about coverage if the chair or vice chair were unavailable, to which Alexander Moser responded that there are currently three chairs, and the proposed change would result in only two. Kevin Hammond agreed that from a procedural perspective, two chairs are likely sufficient, but emphasized that the decision should be made by the larger group.
- Max Block Size Discussion Kevin Hammond noted that the parameter committee has largely processed existing PCPs, with the exception of max block size. Markus Gufler provided statistics indicating that the chain is not heavily loaded, typically operating at about 10% capacity and periodically reaching 50%. While there isn’t an immediate demand for an increase, Markus Gufler and Alexander Moser agreed that increasing the block size could positively impact adoption by signaling capacity to potential projects.
