Overview
The validator key is the cryptographic key a validator uses to sign attestations and blocks in proof of stake. It is distinct from the withdrawal key. Protecting it is critical to validator security.
How It Works
Validators hold a signing key for consensus duties and a withdrawal key for funds. The signing key must be online for duties. Compromise of the signing key can lead to slashing.
Why It Matters
Validator key security is essential for network safety and validator funds. Key management practices prevent slashing and theft. It is a core operational concern.
