Machine Secret

Setting up authentication in prover nodes.

Our prover nodes need a machine secret generated and signed using an imported ECDSA key.

Importing a Private Key

To import an ECDSA private key, use the hex-encoded private key string itself in the OPERATOR_PRIVATE_KEY variable. The 0x hex prefix is optional.

KEY_NAME=prover-node
OPERATOR_PRIVATE_KEY=0x**********************************

fpn store-key -k $KEY_NAME \
              -p $OPERATOR_PRIVATE_KEY

Using existing Private Key

If your current private key file follows the Web3 Secret Storage Definition, you may place the file at ~/.fermah/keys/name.json instead of importing it.

Generating and Adding a Machine Secret Key to the Configuration

This command generates a Machine Secret Key from the imported ECDSA key and updates the configuration file accordingly.

fpn gen-machine-secret

Whitelist Keys

Please provide the Machine Secret public keys through our form at Fermah AVS - Operator Application Form - For Testnet. We will notify you once your key has been registered, upon which you can continue with the remaining steps.
