Following the recent upgrade, node weights have adjusted due to PoC duration normalization.
To normalize PoC weight against actual block generation time, calibration parameters were selected based on observed block intervals. As implemented, the effective PoC reference window turned out to be approximately 5 blocks longer than the prior nominal assumption.
As a result:
- Mean node weights decreased (normalization effect)
- The displayed total H100-equivalent capacity appears proportionally lower
- Relative GPU ratios remain unchanged
Why this happened
Previously, PoC weight calculations relied on a nominal epoch duration assumption. After introducing real-time normalization:
- PoC duration is aligned with the actual block production time
- Weight reflects real compute time more accurately
Because the effective normalization window is ~5 blocks longer than the earlier nominal model, the recalculated weight per epoch is proportionally lower.
Observed GPU weight changes (Epoch 175 → 176)

Action for tracker (dashboard) maintainers
With PoC duration normalization in effect and the effective reference window now ~5 blocks longer than the previous nominal assumption, weight values from Epoch 176 onward reflect the updated calculation model.
Trackers and dashboards that derive H100-equivalent capacity or reward projections from PoC weight should verify their conversion coefficients starting from Epoch 176.
If pre-normalization assumptions are still used, displayed hardware equivalents and projected rewards may appear overstated.
