Further to the conversation and considering the feedback received, the information received has been transposed into the following technical document:
Validator Performance Metrics
-
The performance benchmark (“PB”) is 98% of the Median Average of checkpoints signed by Validators in the Measurement period (“MP”).
-
The MP is the last 700 checkpoints on a rolling basis.
-
Currently this data is shown on Polygon Web Wallet v2 and is based on the last 200 checkpoints (this can be changed to 700 checkpoints).
-
At each checkpoint we calculate the % of checkpoints signed in the MP by each validator and measure against the PB.
Scenario of Validator Underperformance:
The scenario below assumes that the median average of validator performance is 100%, meaning the PB is 98%.
If a Validator falls below the PB in the MP (700 checkpoints ~14 days)
-
Validator A signed 95% of checkpoints in the MP.
-
Validator A enters into the Grace Period (“GP”).
-
They receive a notice stating they have 700 checkpoints to rectify; or they will receive a Notice of Deficiency (“NOD”) .
If a Validator falls Below the PB for a further 700 checkpoints (1400 checkpoints total / ~28 days)
-
In the following 700 checkpoints, Validator A signed 90% of checkpoints.
-
Validator A receives the NOD, stating; “You have not been compliant with the PB for 1400 checkpoints. If not compliant with PB in the following 700 checkpoints you will receive a Final Notice (“FN”) and be kicked with no further resource".
If a Validator falls Below the PB for a further 700 checkpoints (2800 checkpoints total / ~42 days)
-
In the following 700 checkpoints , Validator A signed 92% of checkpoints.
-
Validator A receives a FN of the intent of the community to implement a forced exit procedure by offboarding the validator from the network by unbonding their stake.
