Wall-clock time between consecutive produced blocks in milliseconds, from Trillium slot-duration measurements. The target was 400 ms until August 2026; SIMD-0525 cuts it in 50 ms steps to 350, 300, 250 and 200 ms (October 2026). Slower blocks stretch epochs and lower throughput.

What it shows
The blocks-produced-weighted arithmetic mean of each validator's average slot duration in the epoch. Each validator's contribution is scaled by how many blocks it produced, so high-throughput validators drive the aggregate proportionally and the result reflects the network-wide average experienced across actual block production rather than a simple average over validators.
How it is computed
Each validator's mean slot duration for an epoch is weighted by the number of blocks that validator produced. The network figure is the sum of (mean slot duration times blocks produced) divided by total blocks produced across all validators with valid data. Validators that produced no blocks in the epoch are excluded.
Aggregation: Blocks-produced weighted average across all validators per epoch.
Things to know
- Percentiles here are over the distribution of per-validator epoch means, not over individual blocks. A high P99 means the slowest-producing validators (by weight) averaged that duration, not that any single block took that long.
- Each calendar day is assigned to exactly one epoch based on which epoch contains that day's noon (12:00 UTC). The value is constant across all days that share the same epoch.
- The target slot time steps down from 400 ms to 200 ms under SIMD-0525 (August to October 2026); sustained readings far above the target may indicate cluster stress or validator connectivity issues.
