# Private Blockchain (private DLT) using MultiChain
Application for proposals using blockchain with MultiChain. \
\
Check out our blog if you want to learn more:
- [Java and Blockchain – how to combine these two in business application?](https://asc.altkom.pl/en/blog/java-and-blockchain/)
## Architecture overview
## Repo info
* `multichain-app` - Angular 6 client application
* `multichain-cli` - example test scenario and execute this by MultiChain CLI
* `multichain-cluster` - blockchain infrastructure
* `multichain-server` - Java & Spring Boot & MultiChain Java API
## Architecture
Our solution consists of 5 services:
* `multichain-master` - multichain seed node
* `multichain-slave` - multichain 2nd node
* `multichain-explorer` - multichain 3rd node with UI for browsing blockchain
* `multichain-server` - application backend (Spring Boot + in-memory database)
* `multichain-app` - application frontend (Angular 6 served by nginx)
## Use case
Your organization wants to implement an internal system for submitting different types of applications (for example: request for new equipment). \
Each request must be approved by the manager. \
Requests should be indisputable and immutable.
Example request and decision structure:
```
Request {userId, managerId, creationTime, requestContent}
Decision {managerId, Request, decisionResult, decisionTime}
```
**JSON**:
```
{
"userId": "",
"managerId": "",
"creationTime": "",
"requestContent": ""
}
{
"managerId": "",
"Request": {
{
"userId": "",
"managerId": "",
"creationTime": "",
"requestContent": ""
}
},
"decisionResult": "",
"decisionTime": ""
}
```
## Local development
Remember that `MultiChainJavaAPI` (using to connect with `MultiChain`) is not available in Maven Central Repository so you must build this library locally based on installation instruction in [README](https://github.com/SimplyUb/MultiChainJavaAPI/blob/master/README.md#installation).
## Deployment & running
Each service is packaged as a separate container.
To run whole system you can use `docker` + `docker-compose`.
### Docker Compose
Prerequisites: local docker & docker-compose\
To run application you simply execute command:
```
run.sh
```
Services are started with tty attached to current terminal. \
To stop application just press:
```
Ctrl+C
```
