Decisions/Actions
Decisions
TSC Voting Rights: Current members retain voting rights until the end of this week; new members take over next week post-onboarding.
Parameter Changes: Approved the move to lower minPoolCost to 75 while keeping $K=500$ for now.
Pre-Prod Hard Fork: Confirmed proceeding with the Protocol v11 hard fork (should hard fork working group gives the recommendation tomorrow, 7th May) and Plutus parameter updates on Pre-Prod this week.
Mainnet Strategy: Agreed to a "one epoch delay" between Pre-Prod enactment and Mainnet submission for the Plutus upgrade.
Actions
Bosko: Send onboarding invites and details to newly elected/reelected members this week.
Kevin & Bosko: Coordinate offline to draft the DApp developer communication regarding cost risks.
Kevin: Invite IOG cryptographers to present specific post-quantum risks to Cardano.
Neil & Sebastian: Continue the Leios technical risk discourse in a written, public format (Google Doc).
Bosko & Ryan Williams: Coordinate the submission of governance actions for parameter updates on Pre-Prod and Mainnet based on the agreed timeline.
Topic
Discussion
Notes
TSC Transition
Bosko questioned the legitimacy of votes until new members are onboarded. Kevin and Lorenzo clarified that the current committee remains in force this week.
New members start their term the month after elections (May).
Election Results
Lorenzo announced the election results. Newly elected members will receive onboarding details and attend sessions next week.
Onboarding focuses on policy reminders for new and existing members.
Member Recognition
Kevin congratulated new members whole are elected/re-elected. Outgoing members Sebastian, Nicolas, and Duncan were thanked.
Outgoing members are encouraged to remain as observers/contributors in open meetings.
Committee Terms
Kevin confirmed that incoming members serve a two-year term, expiring in April 2028.
A process for those elected in October to confirm their status until 2027 is forthcoming.
Previous Actions
Bosko reviewed pending actions, including the SEB proposal and expert feedback links for K=1000 and minPoolCost=75.
Alex was absent for the initial part of this review.
Parameter Changes
Neil reported that the Parameters Committee voted to move forward with minPoolCost=75, but delayed K=1000 for further discussion.
A formal Change Proposal (PCP) will be created for the community review.
Communication Plan
Kevin and Bosko discussed a formal plan to inform DApp developers of risks associated with total costs via the Hard Fork Working Group.
Kevin will assist Bosko in articulating the risks offline.
Post-Quantum Risks
Neil requested that IOG cryptographers present specific risks to the Cardano ecosystem rather than general research.
The goal is a self-contained public slide deck on ecosystem-specific risks.
Leios Risk Analysis
Neil presented a risk framing for "Linear Leios," focusing on performance risks and its nature as a preemptive system that discards work.
Neil expressed concern that the system might not have monotonic performance under load.
Leios Response
Sebastian responded to Neil's analysis, arguing that the system is optimistic and that "discarded work" is a small fraction compared to total throughput gains.
Sebastian emphasized that Leios avoids resubmitting transactions already in mempools.
Network Performance
Neil argued that Leios's 12MB data movement requirement might not be achievable transatlantically under certain loss conditions.
Neil views this as a reputational risk if throughput "falls off a cliff" under load.
Protocol Impact
Kevin noted that it must be verified that Leios does not negatively impact the underlying Ouroboros Praos safety arguments.
Sebastian agreed that data availability is the key factor for Praos safety.
Hard Fork Status
Protocol version 11 hard fork on Preview is scheduled for this week, following a successful out-of-band vote.
Enactment is expected shortly after Blockfrost completes its upgrade.
Pre-Prod Upgrades
The committee voted (5 in favor) to proceed with the Plutus parameter upgrade on Pre-Prod as soon as practical.
Submission is pending a heads-up to the Hard Fork Working Group.
Mainnet Schedule
The committee approved a conditional vote to submit the Plutus upgrade on Mainnet one epoch after it is enacted on Pre-Prod.
This ensures at least one epoch of testing on Pre-Prod before Mainnet submission.
