- PrivValidatorSocket uses a socket to send signing requests to another process - user is responsible for starting that process themselves.
The PrivValidatorSocket address can be provided via flags at the command line -
doing so will cause Tendermint to ignore any "priv_validator.json" file and to attempt
to connect over the socket.
doing so will cause Tendermint to ignore any "priv_validator.json" file and to listen
on the given address for incoming connections from an external priv_validator process.
The external priv_validator process will dial the address to connect to Tendermint,
and then Tendermint will send requests on the ensuing connection to sign votes and proposals.
Thus the external process initiates the connection, but the Tendermint process makes all requests.
In addition, Tendermint will provide implementations that can be run in that external process.
