Running the Tupelo RPC server

The Node.js client cannot directly manage chain trees or connect to the notary group, so node applications must instead proxy through an RPC server to work with Tupelo.

To install the server you can download the latest Tupelo executable here.
Once you have selected the appropriate binary for your platform save it within your command PATH variable. If you do not wish to save the binary to a directory in your PATH, you can still execute it with the fully qualified or relative path to your chosen location for the binary.

If you wish to run against the Test-Net please contact us via the feedback form below.

After successfully installing the binary, you can run the RPC server by invoking tupelo (or the full or relative path to your chosen install location if you did not install Tupelo in a PATH directory) along with the necessary options. Production applications will usually connect to an independent notary group, but you can also choose to run and connect to a local notary group to make working in development easier.

Connecting the RPC Server to a Local Notary Group

To start the RPC server and notary group for local development, run:

tupelo rpc-server

This invocation will start a 3 signer local notary group after first generating random keypairs for the group to use. After that, the RPC server will start, bind itself to the local notary group, and listen on port 50051.
