Attestation Effectiveness

Overview

Attestation Effectiveness is a key metric for tracking the overall performance and efficiency of a node’s ability to perform its tasks validating the network. It is formally defined as:

Where if the earliest inclusion slot is also the actual inclusion slot, then a validators Attestation Effectiveness is 100%.

How can I use it?

This indicator is most informative when looking over a longer time range. By tracking the Attestation Effectiveness of one specific vault or the aggregated collection of vaults on Stakewise, a user can identify trends in the overall performance of validators in the protocol. While momentary drops in effectiveness are usually not a large concern, a consistent decline overtime can indicate that the validators are struggling to perform their validating task effectively. If a user sees this occurring in the vault that they have allocated ETH to, they may want to consider switching to another vault to avoid any potential slashing penalties.
