The proposed value is positive and below the maximum permitted value under MPC-01 and MPC-02. The Constitution identifies minPoolCost as a governance-critical parameter and therefore requires the applicable DRep threshold under PARAM-05. The action does not seek to alter the parameter outside the permitted constitutional range.\n\nThe proposed increases to the Plutus memory execution limits are likewise within the applicable constitutional guardrails. maxTxExecutionUnits[memory] would increase from 16,500,000 to 17,500,000, remaining below the 40,000,000 maximum under MTEU-M-01 and within the permitted per-epoch increase under MTEU-M-04. maxBlockExecutionUnits[memory] would increase from 72,000,000 to 77,500,000, remaining below the 120,000,000 maximum under MBEU-M-01 and within the permitted per-epoch increase under MBEU-M-03. The proposed block limit also remains greater than the transaction limit, satisfying MEU-M-01.\n\nThe action provides evidence of prior technical evaluation, including testing of the complete target values on Preview and performance analysis of the proposed Plutus memory increases. The supplied rationale states that the relevant performance analysis found adequate headroom in the critical timing metrics. This is consistent with the Constitution's requirement that changes to technical and network parameters take security, performance, functionality, and long-term sustainability into account.\n\nThe bundling of the changes does not itself create a constitutional violation. minPoolCost belongs to the economic parameter group, while the two Plutus memory limits are directly correlated network parameters. The Constitution does not prohibit multiple parameter changes within a single Parameter Update action where the applicable guardrails are satisfied. The inclusion of the Plutus memory parameters also appropriately brings the action within the SPO voting requirement applicable to parameters critical to the operation of the blockchain.\n\nThe proposed changes are also consistent with the constitutional objectives of long-term sustainability and fair treatment under Article I, ยง 1. The reduction of minPoolCost is intended to address the economic position of smaller stake pools, while the increased Plutus memory limits provide additional execution capacity for applications on Cardano. The Constitution does not prescribe a particular economic setting for minPoolCost, but establishes boundaries within which the parameter may be changed.\n\nThe action therefore remains within the constitutional limits applicable to each parameter and provides technical and economic justification for the proposed changes.", "precedentDiscussion": "This decision affirms that multiple Parameter Update changes may be bundled into a single governance action where each individual parameter change independently satisfies its applicable constitutional requirements and the combination does not create a conflict with the Guardrails.\n\nIt also confirms that a staged parameter change remains constitutionally permissible where each individual step complies with the applicable per-epoch limits. The second step of the Plutus memory increase does not circumvent those limits because the proposed changes themselves remain within the permitted incremental increases.\n\nThe decision further demonstrates that economic parameters may be adjusted in response to changing network conditions and economic circumstances where the resulting values remain within the mandatory Guardrails.", "counterargumentDiscussion": "A potential counterargument is that bundling unrelated changes to minPoolCost and Plutus memory limits could reduce the ability of SPOs or DReps to express independent preferences on each parameter. However, the Constitution does not prohibit bundling Parameter Update changes, and the resulting voting requirements remain those applicable to the governance action as submitted.\n\nA further concern could be that lowering minPoolCost may affect stake pool economics or decentralisation incentives. These are legitimate considerations for voters, but the Constitution does not require minPoolCost to remain at its existing value. The proposed value of 75 ada remains within the mandatory constitutional range, and the action provides an economic and technical rationale for the change.\n\nThe proposed Plutus memory increases could likewise raise concerns regarding network performance. The supplied evidence describes prior testing and performance analysis supporting the proposed values, while the proposed parameters remain within the mandatory limits established by the Guardrails. No constitutional prohibition is therefore identified.", "conclusion": "Tingvard finds this governance action constitutional. The proposed changes to minPoolCost, maxTxExecutionUnits[memory], and maxBlockExecutionUnits[memory] remain within their applicable constitutional Guardrails. The action provides technical and economic justification, and the applicable voting requirements are preserved. Tingvard therefore finds no constitutional basis to reject the action.", "internalVote": { "constitutional": 3, "unconstitutional": 0, "abstain": 1, "didNotVote": 1, "againstVote": 0 }, "references": [ { "@type": "RelevantArticles", "label": "Cardano Blockchain Ecosystem Constitution", "uri": "ipfs://bafkreieyuknozbtewyurfqoagvplvykadn6a4u6wglupavdz46bbsnnl6e" } ] }, "authors": [ { "name": "Tingvard", "imageUrl": "ipfs://QmPkHXdK6GLtDNyyKFBWRwARFEy9TPFcbpDganixmRXwWJ" } ] }
