Slashing Protection

The following are the primary controls Ebunker uses to mitigate slashing risk:

Validator Key Management​

  • Strict permission isolation across the entire lifecycle of key generation, storage, and use
  • The same validator key is never deployed across different environments
  • Complete isolation between production and test environments

Slashing Protection Mechanism​

  • A slashing protection database records the full history of proposals and attestations
  • Mandatory validation on migration or restart to prevent loss of historical state
  • Guarantees that no double vote or double propose can occur in any failover scenario

Migration and Operations Process​

  • Validator migration follows a standard SOP with an approval workflow
  • All migration operations are single-point controlled to avoid parallel execution
  • A new instance is only allowed to start after the old instance is fully decommissioned

DVT Architecture​

  • Distributed Validator Technology (DVT) reduces single-point-of-failure risk
  • Mitigates the risk of duplicate signing caused by single-node anomalies
  • Improves overall fault tolerance and stability

Runtime Security Controls​

  • Continuous monitoring of validator status and signing behavior
  • Alerts on anomalous behavior (e.g. duplicate proposal risk)
  • Conservative failover strategy to avoid risk amplification from rapid switching
