Issues with calendar link synchronization were noted. | Guests Thomas (Intersect) and Adam (IO) were welcomed. | | Security Budget | Discussion on the division of security funds between the Security Council, OSC, and TSC. OSC will not request bug bounty funds as Intersect is the central holder. | TSC/OSC will still oversee the review and program changes for the bug bounty. | | 2030 KPIs: Chain Quality | Leandros consulted IOG researchers to refine "Chain Quality." The recommendation is to use a "Genesis range window" rather than per-epoch. | This implementation improves monitoring of long-range security against potential attacks. | | Election Outreach | Discussion on a post to promote April election applications. Nicolas emphasized neutrality: the TSC account should promote the process, not specific individuals. |


| | TSC Budget Update | Kevin presented the final proposal with a revised review rate of $250 per proposal. Total requested budget is \~$400,000 for 2026. | Deadline for final comments is Monday, April 13th. | | In-Person vs. Virtual | The budget includes funding for 10 workshops. The plan was adjusted to prioritize virtual sessions with fewer in-person events to save costs. | Proposed topics include node performance, post-quantum crypto, and P2P topology. | | CC Minimum Size | Kevin and Alex met with the Civics Committee. They agreed to move forward with reducing the CC minimum size from 7 to 5. | This action is sequenced to follow the Plutus cost model update to prevent governance lockout. | | Plutus Cost Model Risk | Neil highlighted a risk: for the first time, some primitive costs are increasing. Transactions constructed with old pricing data may fail. | A one-month communication "blitz" is planned to warn DApp developers of the changes. | | Node v10.7.1 Status | AWS instances used for benchmarking fell over during evaluation, causing a delay in final performance data for the v10.7.0 fix. | Node v10.7.1 is required to address a 6GB space leak and performance issues found in v10.7.0. | | Linear Leios Prototype | Sebastian shared progress on the Leios prototype, including a new transaction generating tool and early Grafana instrumentation. | Endorsement Block (EB) diffusion is being modeled using Delta-Q to support the security argument. | | Leios "Storm" Threats | Discussion on "storms"—unfortunate timings of VRF elections that could spike network load to 625 MB in the worst case. |


| | Economic Feasibility | Neil raised concerns that high data exchange requirements for Leios might price out small stake pool operators. | The protocol is designed to be optimistic; failure to certify in "storms" is acceptable if the system remains safe. | --- # Agent Instructions This documentation is published with GitBook.
