Setting up a notary service

Corda Enterprise comes with two notary implementations built-in:

  • Single-node: a simple notary service that persists notarisation requests in the node’s database. It is easy to configure and can be used for testing, or networks that do not have strict availability requirements.
  • Highly available: a clustered notary service operated by a single party, able to tolerate crash faults.


To have a regular Corda node provide a notary service you simply need to set appropriate notary configuration values before starting it:

notary : { validating : false }

For a validating notary service specify:

notary : { validating : true }

See Validation for more details about validating versus non-validating notaries.

For clients to be able to use the notary service, its identity must be added to the network parameters. This will be done automatically when creating the network, if using Network Bootstrapper. See Networks for more details.

Highly available

Corda Enterprise provides a highly available notary service implementation backed by a replicated Percona XtraDB cluster. This is the recommended implementation for production networks. See Setting up a HA notary service for detailed setup steps.
