-This tutorial provides an insight into configuring the OAUTH2.0 authentication strategy  (eg. for Google, Facebook, Twitter authentication providers etc) to authorize access to resources in a configured REST Server instance - and allow end users of a blockchain network to interact with a deployed smart contract/business network - the Commodity Trading network in this tutorial (an overview diagram is shown below - a more detailed diagram showing the authentication flow is shown further down). You will run the REST server in [multi user mode](../integrating/enabling-multiuser.html) and test interacting with the network as different blockchain identities, accessing resources through the REST APIs. Ideally, you will need to set up your own Google account / authorization scheme to do this (see appendix on the steps to do this - doesn't take long), or minimally, use the ID/metadata provided in this tutorial. Suffice to say, it uses {{site.data.conrefs.composer_full}} as the underlying blockchain network.
