Data Sources & Collection

TODO: Complete Data Sources Documentation​

Where EigenWatch gets its data and how we ensure quality.

Required Sections​

  • Primary Data Sources

    • Beacon chain (validators, attestations, proposals)
    • EigenLayer core contracts (operators, delegations, slashing)
    • AVS contracts (operator registrations, slashing events)
    • MEV relay data (if relevant to operator risk)
    • Off-chain indexing services

  • Data Collection Strategy

    • Full node vs light client vs service dependency
    • Finality requirements (how many blocks before trusting data?)
    • Reorg handling
    • Data redundancy & validation

  • Data Availability Assumptions

    • What happens if a data source goes down?
    • Fallback mechanisms
    • Impact on risk score accuracy
    • User communication strategy

  • Data Validation

    • Consistency checks
    • Outlier detection
    • Cross-source verification
    • Confidence levels per data point

  • Data Retention & Archival

    • How long is raw data kept?
    • Aggregation/summarization strategy for old data
    • Historical query capabilities
    • Backup & durability

  • Known Limitations

    • Data gaps or blind spots
    • Bias in data collection (e.g., only on-chain data)
    • Latency from event to availability
    • Correction/revision policies

Examples​

  • Beacon chain attestation data latency
  • EigenLayer contract update detection time
  • Off-chain vs on-chain data reconciliation
