Decisions/Actions
Decisions
Budget Strategy: Agreed to wait for the final Intersect main proposal before submitting the revised (reduced) TSC budget to ensure no items fall through the gaps.
Leios Discussion: Moved to conduct a "paper-based" technical exchange between Neil and the Leios team before reserving meeting time for a verbal deep-dive.
Actions
Bosko: Coordinate with Terence to ensure the "updates" Discord channel is opened for public viewing alongside the HFWG channel.
Kevin: Re-confirm the guardrail script testing requirement on Preview with Mike Hornan once the new cost model is enacted.
Kevin: Coordinate with Leonard Hagerty to elevate communication with DApp developers regarding the Plutus cost model risks.
Neil: Create a written summary of specific performance concerns to be sent to the Leios team; Sebastian/Team to respond in writing 48 hours before the May 6th session.
Kevin & Alex: Monitor the Constitutional Committee (CC) member status to determine if the "chained" parameter update (Cost Model -> CC Min Size) needs to be re-ordered.
Topic
Discussion
Notes
Welcome & Quorum
Kevin opened the meeting, confirming seven voting members present (Quorate). Discussions began regarding Daylight Savings shifts and local system issues.
European daylight savings started earlier than other regions, causing minor calendar confusion.
Discord Openness
Terence and Bosko discussed making technical Discord channels (e.g., Hard Fork Working Group) read-only for the public.
Current blockers involve organizational server rules. Updates will be made as organization changes process.
TSC Elections
Bosko reported 10 candidates for 5 open positions. Applications close tomorrow; voting begins next Monday.
Neil and Alex are seeking re-election; Sebastian and Duncan have not reapplied.
Election Events
Terence shared links for upcoming events: Virtual Hub (April 23 & 30) and an X Space (April 28).
Candidates are encouraged to attend to meet voters.
TSC Budget Alignment
Kevin reported on a meeting with Intersect (Jack). Three items originally in the TSC budget were moved to the Intersect main budget.
The moved items are: Technical workshops, part-time meeting organizer, and Security Council member support.
TSC Budget Total
Moving these items reduces the TSC-specific budget request by approximately $150k–$200k.
The revised TSC budget now focuses on two to three core items. Finalization is pending the Intersect main proposal.
Intersect Budget Model
Intersect is reducing its central budget (~$6–7M) by adding a surcharge to individual community proposals to cover administrative costs.
This is intended to create a more sustainable long-term financial model.
Van Rossom Hard Fork
Node 10.7.1 (Mainnet release) is out. Node v11 is expected early next week for testnet forking.
Performance issues found in 10.7.0 (50% CPU spike) have been largely resolved.
Hard Fork Timeline
Mainnet hard fork action submission is currently targeted for May 28, 2026, assuming sufficient stakeholder adoption.
Technical risks are largely burning down; focus is shifting to social readiness and DApp testing.
Plutus Cost Model Risks
Discussion on the risk of locking out guardrail scripts or DApps due to cost model changes.
Leonard is coordinating with the top 10–20 DApp developers to ensure no breaking impacts.
Dextra Scoping
Ryan presented a "maximalist" list of SIPs for the Dextra era. Many SIPs are already covered in other budget work packages.
The committee discussed how to prioritize without creating redundancy.
Leios Performance
Neil raised serious concerns about Leios performance feasibility based on an AI-assisted analysis of current throughput constraints.
Sebastian noted that the analysis may have missed recent documentation/claims from the Leios repository.
2030 Vision KPIs
Leandros and Kevin are meeting with the Product Committee immediately after this call to finalize the baseline metrics.
Discussion continues on whether to use Genesis range windows vs. per-epoch for security measurements.
