Hiero Technical Steering Committee Meeting

TL;DR: The TSC kicked off the new year with a focus on (1) closing out prior minutes and transitioning future minutes to the governance wiki, (2) performance and developer-experience priorities for the year, (3) a HIP update on a new “high-volume entity creation” throttle lane, and (4) a proposal to create a Hiero “roadmap” repository, which will proceed via an asynchronous GitVote.

Meeting Summary

• Opening notes

  • Brandon Davenport chaired in Hendrik Ebbers’ absence and reiterated that the meeting is open to the public.

• Approval of previous minutes / minutes process change

  • Brandon noted several prior meeting minutes PRs still pending approval in the hiero-ledger/tsc repo (the “old” minutes process).
  • Going forward, new TSC minutes will be stored in the governance wiki/repo, with this meeting intended to be the first entry after closing out the remaining prior PRs.

• Community/member updates

  • Richard Bair provided a “start of year” perspective on priorities and themes:
    • Ongoing stream of HIPs, features, and improvements (including discussions like Paymaster-related work).
    • A major emphasis on performance improvements, especially:
      • Reducing end-to-end latency (noting current ~3 seconds to consensus and higher end-to-end including downstream components), with an aspirational goal of an order-of-magnitude improvement (e.g., hundreds of milliseconds in the best case).
      • Exploring dynamic throttles to better utilize available capacity while protecting the network under varying transaction mixes and heterogeneous node hardware.
    • Additional technical direction:
      • Continued cleanup after prior modularity work (acknowledging real-world complexity of large refactors).
      • Improving extensibility so teams can add custom services without forking, by dropping in modules more cleanly.
      • A stronger, more coherent developer experience approach across SDKs and related tooling (consensus, mirror, JSON-RPC/relay, block node), emphasizing “bottom-up” adoption by delighting developers.

• HIPs board review / HIP 1313 update

  • The group reviewed the HIP tracker at a high level.
  • Joseph Sinclair (with context from Ty Smith) summarized HIP 1313, describing a separate throttle “lane” for high-volume entity creation (e.g., creating many accounts quickly):
    • Users may opt into the lane and pay higher fees in exchange for higher entity-creation throughput.
    • Joseph emphasized: “This is not a priority link. This is a capacity lane.” Ordering remains unchanged; it only affects allowable throughput.
    • The high-volume throttle is separate from regular throttles so that spikes can proceed without shutting down normal traffic.
    • A follow-up HIP is expected to extend the approach to EVM smart contracts.
    • Noted as needing TSC approval (with TECOM approval mentioned).

• Project proposal presentation: Roadmap repository

  • Steven S presented the proposal to create a Hiero “roadmap” repository as a tracking repo (issues + GitHub Project board), intended to tie together cross-repo initiatives and epics and eventually be made public.
  • Discussion highlights:
    • Desire to start as a private PoC to validate tooling/approach, then open it once proven.
    • Rationale for hosting inside the Hiero GitHub org: easier linking/searching across Hiero repos versus cross-org limitations.
    • Consensus in the room that it is low risk (can be reversed if needed).
  • Next step agreed: proceed with an asynchronous GitVote for the proposal.

• AOB / close

  • No additional business raised.
  • Brandon closed the meeting and noted Hendrik would return for the next call.

Presentations (optional)

• Richard Bair: Year-ahead priorities: performance (latency + dynamic throttles), modularity/service extensibility cleanup, and a more cohesive developer experience across SDKs and tooling.
• Joseph Sinclair / Ty Smith: HIP 1313 overview: optional high-volume entity-creation throttle lane with higher fees; not priority ordering; separate capacity lane.
• Steven S: Project proposal to create a roadmap repository and associated GitHub Project board for high-level initiatives and cross-team tracking.

---

Key Decisions

• Proceed with an asynchronous GitVote on the roadmap repository proposal (Issue #272).
• Confirmed intent to transition minutes going forward to the governance wiki/repo, after closing out the remaining prior minutes PRs in the TSC repo.

---

Action Items

• TSC members: Add approvals / merge outstanding prior meeting minutes PRs in the hiero-ledger/tsc repo to close out the previous minutes process.
• TSC members: Participate in the GitVote for the roadmap repository proposal (Issue #272) within the stated voting window.
• Owners of HIP 1313: Follow up on the remaining TSC approval step and confirm next steps/timeline for implementation and the EVM follow-on HIP.
