Validator

The validator verifies submitted transactions and proposed blocks before signing blocks for the sequencer. It is an internal service and should not be exposed publicly.

Start

miden-validator start \
  --listen 0.0.0.0:50101 \
  --data-directory validator-data

For local development, the validator can use its default insecure development key. Production deployments should configure validator signing explicitly, either with a local key or with KMS-backed signing.

Use miden-validator start --help for the complete current option list.
