Compliance, per cluster

Each criterion below compares a measured value against the threshold the program published for that cluster and epoch. The dashed line is the limit; the bar is the measurement. Nothing here is hardcoded: change the epoch and the limits move.

Program grade history

The grade the program assigned for each epoch it assessed. Bonus met the higher bar that earns additional stake; Baseline met the requirement without it; Nonemeans the epoch’s requirements were not met. An epoch with no grade at all was not assessed: it counts as neither pass nor fail, and renders as an empty track. Select a tile to read that epoch’s detail, including the failure reason where the program published one.

The program graded this validator before its recorded join date, so it was taking part earlier than that date implies. No earlier join date is published, so the graded span is the only evidence of when participation began.

“Graded span” is the first and last epoch the program published a grade for. For a validator no longer participating, the last graded epoch is strong evidence of when that ended, but the program states no exit date, so none is claimed here. Dates prefixed ~ are interpolated between known epoch boundaries.

Failure reasons are the program’s own machine-readable codes, collected by this site into a committed file; collection is still running, and the program published no reasons at all for most failures before roughly epoch 600. An unexplained failed epoch is still a failed epoch.

Slot time

Average slot duration on mainnet-beta, wall clock between consecutive slots, from Trillium, not from the Solana Foundation: the program publishes no slot timing at all, so this is one of two figures here that are not its own, alongside IBRL block build time.

range 333.2 to 414.6ms · observed across this window: the last 5 readings average 30.9ms slower than the first 5

Where this comes from

Each epoch’s figure is Trillium’s own per-validator mean slot duration, and the headline is their unweighted average, one vote per epoch. 410ms is where Trillium’s slot_duration_is_lagging flag flips: across the 658 validators it had data for in epoch 1009, every one it flags sits at 410.02ms or slower and every one it does not sits at 409.87ms or faster, with no overlap. 426ms was the cluster’s own mean slot duration that epoch.

The Solana Foundation publishes no slot timing and sets no such limit: its per-epoch endpoint carries 29 fields and not one is a duration. Nothing here counts toward the program’s grades. Read from a snapshot committed to this repository, taken 2026-08-18 04:15:17 UTC, covering 449 validators on mainnet-beta. Nothing is fetched while this page renders.

The other source measures something else. Switching it changes the quantity on the axis, not the vendor reading one quantity: across the validators carrying both, slot duration and block build time correlate at 0.57, half of them differ by more than 15ms and one by 78ms. Coverage differs too, so a validator can carry a figure under one source and none under the other.

Vote credit history

The last 64 epochs on each cluster, as a share of the credits achievable that epoch. The dashed line is the program’s floor converted to that same measure, so the two are genuinely comparable. Each axis is zoomed to its own data, with its range stated beneath the plot.
