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.

Bonus: passed, full-height bar

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.

Build time

Median time the leader took to build a block on mainnet-beta, from IBRL, not from the Solana Foundation: the program publishes no measure of block building at all, so this is one of two figures here that are not its own, alongside Trillium slot duration.

Dashed lines: 410ms and 426ms. This site’s cut points, published by neither IBRL nor Trillium: IBRL bands no build time, and Trillium never measured it. They are the slot-duration marks, reused so the scale holds when you switch source. Neither is a Solana Foundation limit.

range 404.0 to 421.0ms · observed across this window: the last 5 readings average 4.8ms faster than the first 5

Where this comes from

Each epoch’s figure is IBRL’s own median_block_build_msfor that epoch, stored exactly as published, and the headline is the newest of them rather than an average: IBRL publishes no multi-epoch aggregate, and a mean of ten medians would be this site’s arithmetic wearing IBRL’s name. The 410ms and 426ms lines are this site’s cut points and belong to neither vendor: IBRL publishes no band for build time, and Trillium never measured build time at all. They are the marks the slot-duration scale uses, reused here because both distributions sit in the same range, so switching source does not move the scale.

The Solana Foundation publishes no measure of block building and sets no such limit: its per-epoch endpoint carries 29 fields and not one of them is about how a block was built. Nothing here counts toward the program’s grades. Read from a snapshot committed to this repository, taken 2026-08-18 04:15:38 UTC, covering 450 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.
