Decisions/Actions

Decisions

• Governance Ordering: Provisional agreement to prioritize the Plutus cost model upgrade ahead of the Constitutional Committee (CC) minimum size reduction.

• KPI Measurement: Adopted the recommendation to measure chain quality over a rolling Genesis window for improved long-range security.

• Budget Ratification: The committee approved the revised 4-work-package budget structure for submission to the Intersect Board.

Actions

• Kevin: Sync up with Udai to clarify the final division of the security budget between the TSC and OSC.

• Kevin & Bosko: Coordinate a Doodle poll to schedule the private technical deep-dive on Linear Leios risk management with Sebastian.

• Ryan: Prepare a maximal list of "forkable" CIPs in coordination with Ryan Williams for the upcoming community poll.

• Leandros: Update the 2030 KPI document with the "Genesis range window" implementation details and share it in Slack.

• TSC Account: Promote the April election applications via X (Twitter), specifically targeting prospective technical candidates.

• Neil: Finalize the "Professional Technical Review" proposal draft to address the $150/review rate concerns before the budget is final.

• Bosko: Investigate the feasibility of an RSS feed for technical parameter updates to improve developer communication.

Topic	Discussion	Notes
Welcome & Quorum	Kevin opened the meeting, noting that only four voting members were present. All decisions made require ratification outside the meeting.	Guest attendees included Thomas and Adam.
Security Budget Alignment	Discussion on items related to the Security Council and budget overlaps between the TSC, OSC, and Intersect central funds.	Alignment reached: OSC will not request bug bounty or incident officer funds as they are in the Intersect proposal.
Bug Bounty Oversight	TSC and OSC members will jointly oversee the disbursement of the bug bounty program, despite Intersect being the budget holder.
2030 KPIs: Chain Quality	Leandros met with IOG researchers to refine "Chain Quality." The recommendation is to use a "Genesis range window" rather than per-epoch.	This provides a better indicator of security against long-range attacks.
Technical Communication	Bosko is investigating the feasibility of an RSS feed for TSC updates to improve accessibility for the technical community.	The request for a dedicated TSC communications officer was lifted to the Intersect level.
CC Minimum Size	Thomas reported that the Civics Committee voted to support a governance action to reduce the committee minimum size from 7 to 5.	Submission is targeted for the current epoch if it does not conflict with the Plutus cost model update.
Plutus Cost Model Risks	Neil expressed concern that the upcoming cost increases for pre-existing primitives might cause "lazy" transactions to fail at the epoch boundary.
Governance Sequence	The committee debated the order of parameter changes. Adam suggested the Plutus cost model is less controversial than the CC size change.	Final decision: Plutus cost model first, followed by CC minimum size two epochs later.
TSC Budget Proposal	Kevin presented the revised budget of ~$400,000, reduced to four work packages. $20,000 was added for security council member support.	Work packages cover community coordination, security, protocol governance, and technical review.
Workshop Strategy	The budget includes 10 technical workshops. Based on feedback, the majority will be virtual, with four face-to-face events collocated with summits.	Topics include Layer 2, node performance, and post-quantum cryptographic resilience.
Technical Review Pilot	A pilot "Independent Technical Review Program" is planned for 2026 to build a pool of experts for the 2027 budget cycle.	The proposed rate is $150 per review, which Neil argued is too low for high-stakes delivery projects.
Hard Fork Risk: Node v10.7	Node v10.7.0 was found to have serious performance issues and rare consensus failure conditions. It is not Mainnet ready.	Focus has shifted to Node v10.7.1; the tentative hard fork forecast is now June 2026.
SIP-179: Surveys & Polls	Thomas and Ryan demonstrated a tool for on-chain surveys via metadata. This will be used to shortlist SIPs for the Dextra hard fork.	The tool is integrated with CGov and allow DReps to vote on specific hard fork content.
Net Change Limit (SIP)	Ryan discussed the technical feasibility of an on-ledger Net Change Limit (NCL). It requires the ledger to track revenue history for 73 epochs.	Consensus is shifting toward ledger-level enactment at the point of withdrawal rather than a guardrail script at submission.
