Foghorn

Observability

Block-pinned GraphQL probes dispatched via The Graph gateway. Latency and response consistency observed across all allocating indexers.

Deployments

Methodology. Foghorn dispatches identical GraphQL queries via The Graph gateway, which load-balances across allocating indexers. Responses are stripped of volatile fields, canonicalized via JCS (RFC 8785), and hashed with SHA-256. Latency is measured gateway-to-response. Allocation keys are recovered via EIP-712 ecrecover against the DisputeManager domain.

No verdict. Foghorn does not label, rank, or flag indexers. Observations are neutral — consumers draw their own conclusions.
