Raise the block compute limit by 25%

Lift the per-block compute limit from 48 M to 60 M units after three months of testnet data showed validators have headroom.

VotingBy Protocol working groupOpened 22 September 2026 · closes 6 October 2026

Motivation

Blocks have run above 85% of the compute limit at peak hours for eight consecutive weeks, which pushes fees up for everyone.

Testnet has run at 60 M units since June with no increase in missed slots among validators that meet the published hardware guide.

Specification

  1. Set MAX_BLOCK_COMPUTE to 60,000,000 at the first epoch boundary after the vote closes.
  2. Keep the per-transaction limit unchanged at 1,400,000 units.
  3. Review missed-slot rates after 30 days and report on this page.
