Angular 6 client application\n* `multichain-cli` - example test scenario and execute this by MultiChain CLI\n* `multichain-cluster` - blockchain infrastructure\n* `multichain-server` - Java \u0026 Spring Boot \u0026 MultiChain Java API\n\n## Architecture\n\nOur solution consists of 5 services:\n* `multichain-master` - multichain seed node\n* `multichain-slave` - multichain 2nd node\n* `multichain-explorer` - multichain 3rd node with UI for browsing blockchain\n* `multichain-server` - application backend (Spring Boot + in-memory database)\n* `multichain-app` - application frontend (Angular 6 served by nginx)\n\n## Use case\nYour organization wants to implement an internal system for submitting different types of applications (for example: request for new equipment). \\\nEach request must be approved by the manager. \\\nRequests should be indisputable and immutable. \n\nExample request and decision structure:\n```\nRequest {userId, managerId, creationTime, requestContent}\nDecision {managerId, Request, decisionResult, decisionTime}\n```\n\n**JSON**:\n```\n{\n\t\"userId\": \"\",\n\t\"managerId\": \"\",\n\t\"creationTime\": \"\",\n\t\"requestContent\": \"\"\n}\n\n{\n\t\"managerId\": \"\",\n\t\"Request\": {\n            {\n                \"userId\": \"\",\n                \"managerId\": \"\",\n                \"creationTime\": \"\",\n                \"requestContent\": \"\"\n            }\n\t},\n\t\"decisionResult\": \"\",\n\t\"decisionTime\": \"\"\n}\n```\n\n\n\n## Local development\n\nRemember 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).\n\n## Deployment \u0026 running\n\nEach service is packaged as a separate container.\nTo run whole system you can use `docker` + `docker-compose`.\n\n### Docker Compose\n\nPrerequisites: local docker \u0026 docker-compose\\\nTo run application you simply execute command:\n\n```\nrun.sh\n```\n\nServices are started with tty attached to current terminal. \\\nTo stop application just press:\n\n```\nCtrl+C\n```\n\n## Screens\n\u003cp align=\"center\"\u003e\n    \u003cimg alt=\"Desktop main version\" src=\"https://raw.githubusercontent.com/asc-lab/blockchain-multichain/master/images/multichain_desktop_main.png\" /\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n    \u003cimg alt=\"Mobile menu\" src=\"https://raw.githubusercontent.com/asc-lab/blockchain-multichain/master/images/multichain_mobile_menu.png\" /\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n    \u003cimg alt=\"Initial users\" src=\"https://raw.githubusercontent.com/asc-lab/blockchain-multichain/master/images/multichain_user_list.png\" /\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n    \u003cimg alt=\"Request list\" src=\"https://raw.githubusercontent.com/asc-lab/blockchain-multichain/master/images/multichain_request_list.png\" /\u003e\n\u003c/p\u003e\n\n\u003cp align=\"center\"\u003e\n    \u003cimg alt=\"Decision list\" src=\"https://raw.githubusercontent.com/asc-lab/blockchain-multichain/master/images/multichain_decision_list.png\" /\u003e\n\u003c/p\u003e\n\n## DOCS\n\n* [Getting started](https://www.multichain.com/getting-started/)\n* [JAVA API](https://github.com/MultiChain/multichain)\n* [MultiChain -
