Solana Validator Effectiveness Rating

Methodology that underlies the effectiveness rating of validator and operator performance on Solana.

This effectiveness rating is a measure of how well a validator has been performing its rewarded duties over time.

It seeks to be a true measure of performance, attributing points to the validator for attributes of their onchain footprint that they have influence over (e.g. whether they are successfully voting for slots, which means they are actively participating in consensus), while dampening the effect of metrics that allow randomness to creep into the measurement (e.g. voting performance of other validators).

The Solana Effectiveness Rating is designed to work with the validator’s vote account as the base unit of account. What the metric effectively does is to tally up the duties that a validator is called to perform over a given time period (e.g. 2 epochs, a day, a year), and assign points to those instances when duties were completed successfully. The result is a percentage score that illustrates the job completion rate of a given validator vote account.
