Title
Increase Transaction and Block Memory Units (Part 1 of 2)
Abstract
Intersect's Parameter Committee proposes the first of two Parameter Update governance actions. The following change is proposed together in this rationale, but will require two separate, linked governance actions as per guardrail MTEU-M-04.
1) increase Plutus script memory unit limits per transaction by 25% to allow greater flexibility for DApp developers.
2) increase Plutus script memory unit limits per block by 25% to remain consistent with the current block memory limits.
No other protocol parameters or Plutus cost model setting will be changed.
Motivations
Community members have expressed a desire to increase the Plutus script memory unit limits to simplify DApp development and enhance scalability - see [PCP-003](https://forum.cardano.org/t/pcp-003-max-tx-ex-mem-pilanningham/125506) and [public survey results](https://cardanocommunity.typeform.com/report/rjRd2Fn0/UYLpnsukGSDRPJ4r).
Raising `maxTxExecutionUnits[memory]` and `maxBlockExecutionUnits[memory]` could significantly improve Plutus script throughput with minimal impact on block propagation or node performance, making it a low-risk and high-impact change.
