While we have a license notice in the headers (which is great), we do not provide an actual LICENSE file. We really should do that because that holds all the terms and conditions of usage of the code.

When I follow build instructions in docs/devops/Compose.md,
I am able to sucessfuly run all steps up to docker-compose up -d notary mfcorda tccorda sacorda.
After that docker logs -f mfcorda outputs me an error, from which I assume that the build goes wrong:

  docker logs -f mfcorda

Hi Team, in docker-compose.yml, there is no SovrinAgent Corda node and web configurations, but in docs/devops/Compose.md, it still has the docker-compose command for sacorda and saweb, so I need to remove them from the command to make compose work.

May I know why SovrinAgent has been removed? If I still would like to get the knowledge about its CorDapp and backend services, where can I get it? Kindly advise.

Thanks

Hi team,

I'm trying to build & run the demo. For the moment I managed to deployed the Android app and the frontend, but I am not pretty sure how to deploy/run the Corda nodes and/or web app services. How can I run those nodes?

Some remaining questions on my sides:

• When the Frontend is running, is it possible to access it by IP address rather than "localhost"?
• The Android app can actually scan the QR code from Treatment center, and the next scenario can continue if I am correct?
• Where can I see the usage of IndyService (from the concept of Cordentity github) in this POC?

Many thanks for your help and have a great day,
AD

PS: I've managed to run the Corda Nodes by running the runnodes script in the build/nodes folder

Hi Team, I am using Virtual Box in my Macbook, and Ubuntu 18.04 as the OS, when running the deployJarsToNodes task, there is one error that the "cordentity-cordapp-contracts-states" jar could not be downloaded, read time out. Could you please provide some suggestion how should I fix this issue? Thanks.

Can one fork this to extend this to store one's identity? And how scalable is this platform with respect to the number of patients and nodes?

I got the error below when I tried to run Corda nodes.

[ERROR] 09:59:13+0300 [main] internal.NodeStartupLogging. - Exception during node startup: Incompatible schema change detected. Please run schema migration scripts (node with sub-command run-migration-scripts). Reason: Schema-validation: missing table [CredentialDefinitionSchemaV1$PersistentCredentialDefinition]

I guess SQL table xmls are missing. How did you use this library without these xmls?
I am not sure this project is the right place for this issue but Cordentity project is archived now.

Some of the frontend stuff seems to require xterm for running, ignoring the default terminal settings.

Add an executable file to /bin/xterm with

#!/bin/bash
x-terminal-emulator "$@"
