The alice/faber demo is widely used in the indy-sdk demo. The description of the VCX node demo explains it well, including the operation of the cloud agent. Description here.

Before you'll be able to run demo, you need to make sure you've compiled

• libindy
• libvcx
• libnullpay
• Optionally libindystrgpostgres if you want to run demo with postgres wallet.

Library binaries must be located /usr/local/lib on OSX, /usr/lib on Linux.

You can skip this step because this code gets the pre-built LibVCX wrapper from skt-develop maven repository.

Or you can build and use the LibVCX wrapper. Instructions here.

See dependencies section in build.gradle.

You can skip this step because this code uses the skt testnet.

Or you can run pool of Indy nodes on your machine. You can achieve by simply running a docker container which encapsulates multiple interconnected Indy nodes. Instructions here.

See genesis_path of vcxConfig variable.

You can skip this step because this code uses the skt test dummy cloud agent.

Or you can run dummy cloud agent on your machine. Instructions here.

See agency_url of provisionConfig variable.

• Run Faber agent, representing an institution

./gradlew faber

• Give it a few seconds, then run Alice's agent which will connect with Faber's agent

./gradlew alice

You can also run demo in mode where both Faber and Alice are using Postgres wallets. Follow instructions to compile postgres wallet plugin and startup local postgres docker container.

Once you have that ready, use these commands to start demo in postgres mode.

./gradlew faber_pg

./gradlew alice_pg

Another feature are webhook notifications. The above demo works based on polling, but when using webhook feature, it works based on notification.

./gradlew webhook_faber

./gradlew webhook_alice

Faber receives messages of dummy cloud agent at localhost:7201/notifications. Similarly, Alice receives at localhost:7202/notifications. The action is performed based on the message received, which is briefly described below.

When Alice starts, it automatically gets an invitation from Faber's localhost:7201/invitations. So, in a situation where Faber is running normally, run Alice.

Since LibVCX does not provide APIs to register a new DID, this code was written using LibIndy.

• Usage (default) - SEED (Keyphrase of DID): Random, ROLE: ENDORSER, ALIAS: null

./gradlew register_did

• Usage with parameters (can be omitted)

SEED=00000000000000000000000Endorser1 ROLE=ENDORSER ALIAS=faber ./gradlew register_did
