A-ETH-IntegrityBPS
Audited BPS: 8316Executive Summary
In the pre-agentic economy, this function was performed by a rotating cast of Senior SREs and Infrastructure Architects who spent 12-16 hours weekly in a fragmented workflow: Monday morning, the on-call SRE would manually pull Prometheus metrics into a local Jupyter notebook, calculate error rates and latency percentiles across six component classes, then paste results into a shared Google Sheet where a Platform Engineer would manually weight each component (consensus 30%, execution 25%, etc.) and compute a composite risk score using Excel formulas—a process that took 3-4 hours and was error-prone due to copy-paste mistakes and stale metric timestamps. Simultaneously, the Validator Operations Engineer would review Beaconcha.in attestation data and cross-reference it against Grafana dashboards showing peer counts and sync distance, manually assessing whether the validator infrastructure was at risk of slashing or missing proposals. When incidents occurred, the Incident Commander would manually correlate these disparate signals (a spike in RPC error rates, a drop in peer connectivity, elevated latency on the execution layer) by jumping between Grafana, Prometheus, Slack threads, and PagerDuty, making judgment calls about whether to trigger failover based on intuition and past experience rather than deterministic mathematical models. The entire workflow was chained to Excel (for risk scoring), Grafana (for metric visualization), Prometheus (for data source), Jupyter (for ad-hoc analysis), Slack (for coordination), and PagerDuty (for alerting)—a Rube Goldberg machine of tools that introduced 4-8 hour detection latencies, required constant manual validation, and created single points of failure when key personnel were unavailable. This synthesis function eliminates that entire manual pipeline by encoding the domain expertise of Ethereum infrastructure operations into a pure, deterministic computation that runs every 60 seconds, automatically correlates all six component classes, applies mathematically rigorous failure probability functions with cascade propagation modeling, and delivers actionable directives (ALERT, INTERVENE, FAILOVER, HALT) without human interpretation—transforming infrastructure risk assessment from a labor-intensive, error-prone, asynchronous process into an automated, consistent, sub-second decision engine.
