We track validator performance over several dimensions and assign a score in the range of (0..2) for each. The scores also correlate with colored icons: is excellent, is OK, and means there is room for improvement. The scored dimensions are:
Root Block Distance measures the median & average distance in block height between the validator and the tower's highest block. Smaller numbers mean that the validator is near the top of the tower. (2 points) means that the validator median block distance is at, or below, the cluster median. (1 point) means that the validator average block distance is at, or below, the cluster average. (0 points) means that the validator average is higher than the cluster average. The medians and averages are calculated over a trailing 2-day period and do not reset with each epoch.
Vote Distance is very similar to the Root Block Distance score above. Lower numbers mean that the node is voting near the front of the group. The scoring rules are the same as Root Block Distance above.
Skipped Slot % measures the percent of the time that a leader fails to produce a block during their allocated slots. A lower number means that the leader is making blocks at a very high rate. (2 points) means that the validator skipped slot % is at, or below, the cluster median. (1 point) means that the skipped slot % is at, or below, the cluster average. (0 points) means that the validator average is higher than the cluster average. The medians and averages reflect the current epoch, and the stats reset with each new epoch.
Published Information Investors or delegators want to know who is running a node. The Published Information Score measures the contact information that the validator has posted to the blockchain using the `solana validator-info` feature. (2 points) means that the validator has published all four data elements (Name, Keybase ID, Website URL, and Details). (1 point) means that the validator has published two or three parts. (0 points) means that the validator has published only one, or zero, pieces of contact data.
Software Version This score is based on the Solana software version currently in use on this node. (2 points) means that the validator is using the correct major, minor, & patch versions. (1 point) means that the validator is using the correct major, & minor versions (but not patch). (0 points) means that the validator is only using the current major version (or less). This score is updated as soon as the validator starts voting with a new software update.
Security Report Security and operations are a critical component of a well-run validator. I am assigning one (1) point when a validator has provided me with a URL to their web page related to security policies. Please be aware that I am not evaluating the content on that web page. I will merely confirm that the web page discusses security or operating procedures before posting the link to this site. (1 point) means that the validator has provided a valid URL. (0 points) means that the validator has not published a description of their security policies. (Validators, please directly contact Brian Long to provide the URL.
Stake Concentration is a contra-score and will DEDUCT points from a validator's total score. (-2 points) means that this validator controls over 6% of the active stake. (-1 point) means that this validator has more than 3% of the active stake. The concentration of stake is a bad thing on a decentralized proof-of-stake blockchain. There is no deduction of points, and no icon, if the validator controls less than 3%. If you are an investor who is delegating stake, please consider high performing nodes without high stake concentrations.
Data Center Concentration COMING SOON -- another contra-score that will DEDUCT points from validators located in data centers that host a high percentage of other Solana validators. A high data center concentration means that a problem with the hosting provider could take a high % of the nodes offline. If you are an investor who is delegating stake, please consider high performing nodes without a high data center concentration.
The maximum score is currently eleven (11) points:
Volunteer node operators run a script on their machines to ping all of the other cluster nodes. The script sends the ping times to this website for analysis.
