Configuration

Prover Nodes have pre-made configuration files available based on the information provided through the application form.

In order to download these configuration files, you can get them using our Install Script from installation.

During installation, make sure you provide your assigned prover node name, so it fetches the right configuration file.

Notes

Running the Install Script sets up a configuration file corresponding to your prover node, containing information about:

Network endpoints and contracts
Keystore
Hardware resource claims and prices
Prover capabilities
Telemetry config

The TOML configuration file is expected to exist in ~/.fermah/config/prover-node-config.toml.

For Mainnet, we are currently handling the creation of these configurations from our side for smooth onboarding.

Example Configuration

`~/.fermah/config/prover-node-config.toml`

The following fields should be customized for each prover node:

All [hardware] entries must reflect the server HW resources.
Prover fields such as [zksync]
