Why we run these checks
We need to ensure that when we route traffic to your node, the response is correct and fresh. Two things can go wrong:- Incorrect results — The node returns data that doesn’t match what the network actually has.
- Stale data — The node is behind the chain tip, so responses are outdated.
Types of checks
- Replay checks — Verify that your node returns correct results. We compare your node’s response to what we observe from the network.
- Lag checks — Verify that your node is up to date with the chain. Nodes that are too far behind the tip may be temporarily removed.
- When checks fail — What happens after a failure and where to see your results in the portal.
