How well the validator set is doing its job each day. Every epoch, validators are expected to attest (to vote on the head of the chain). This chart plots the daily participation rate: of all attestations expected, the percentage actually included on-chain. It is a liveness and health measure, not a count of validators; a high rate means validators are online and the consensus layer is healthy, while dips signal validators going offline or network trouble. QRL 2.0 only (the Proof-of-Work chain has no validators).

FAQ about this chart
Common questions about this page+
What does the attestation rate chart show?
It shows the daily attestation participation rate of the QRL 2.0 validator set: of all the attestations validators were expected to make that day, the percentage that were actually included on-chain. Each epoch, validators attest to the chain head; this chart measures how reliably they did so.
How is this different from the number of validators?
The validator count tells you how many validators exist; the attestation rate tells you how well they are performing their duty. You can have many validators but a low attestation rate if a lot of them are offline or out of sync. This chart is a liveness and health signal, not a roster.
What does a low or jumpy rate mean?
On a mature network the rate sits near 100%. A low or volatile rate means validators are repeatedly missing their attestations — common on a young network where nodes go up and down. Sustained dips on an established network would indicate a consensus or connectivity problem.
Why is there no attestation rate for the Proof-of-Work chain?
Attestations are a Proof-of-Stake consensus mechanism, and only QRL 2.0 runs a beacon chain with validators. The original Proof-of-Work chain secures blocks by mining, so it has no validators and no attestations to measure — hence the QRL 2.0-only badge.
