+# Pengembangan Sistem Audit Rekam Medis Menggunakan Teknologi Blockchain
+
+Repositori ini berisi <i>source code</i> untuk pengembangan sistem audit rekam medis berbasis blockchain.
+
+## Gambaran Proyek
+
+Dalam proyek ini terdapat 3 node peer dan 1 node orderer. Keempat peer tersebut dijalankan pada 3 pc desktop menggunakan docker swarm dengan detail sebagai berikut:
+
+- PC 1 (Ubuntu 24.04.3): PC 1 ini sebagai host docker swarm dan menjalankan peer serta orderer.
+- PC 2 (Ubuntu 24.04.3): PC 2 ini sebagai worker docker swarm pertama dan menjalankan peer.
+- PC 3 (Windows WSL dengan distro Ubuntu 24.04.1): PC 3 ini sebagai worker docker swarm keuda dan menjalankan peer.
+
+Proyek ini mengimplementasikan sistem rekam medis menggunakan teknologi blockchain dengan rincian sebagai berikut:
+
+- Hyperledger Fabric sebagai framework blockchain dengan chaincode dibangun menggunakan bahasa pemrograman javascript.
+- Mekanisme konsensus RAFT untuk <i>ordering service</i>.
+- PostgreSQL sebagai basis data dan penyimpanan rekam medis offchain.
+- REST API Gateway sebagai penghubung antara pengguna dan jaringan blockchain, dibangun menggunakan javascript.
+
+## Struktur Repositori
+
+- `/backend` - Folder backend yang di dalamnya terdapat kode program backend api dan blockchain.
+- `/frontend` - Folder frontend yang di dalamnya terdapat kode program frontend.
+
+## Prasyarat
+
+- Docker & Docker Compose
+- Node.js (v20 atau lebih tinggi)
+- Instalasi Hyperledger Fabric (v2.5.13)
+- Jika menggunakan Windows, pastikan WSL2 telah diinstal dan diaktifkan serta jalankan proyek ini di dalam WSL2.
+- PostgreSQL (PostgreSQL 16.11 atau lebih tinggi)
+- **Pastikan semua pc/vm yang digunakan memiliki IP Statis**
+- **Pastikan port berikut tersedia karena diperlukan untuk koneksi docker swarm: 2377 (TCP), 7946 (TCP/UDP), 4789 (UDP)**
+
+## Instalasi
+
+1. Clone repositori
+2. Masuk ke direktori [network](/backend/blockchain/network/), ikuti instruksi di file `README.md` untuk konfigurasi jaringan Hyperledger Fabric.
+3. Masuk ke direktori [chaincode](/chaincode), ikuti instruksi di file `README.md` jika ingin mengubah logika bisnis dalam smartcontract, jika tidak, lanjut pada langkah ke-4.
+4. Jalankan command berikut di pc/vm yang akan menjadi gateway utama/docker swarm leader:
+   ```bash
+   docker swarm init --advertise-addr [IP_PC_UTAMA]
+   ```
+5. Kemudian jalankan command berikut untuk mendapatkan token docker swarm yang akan digunakan pc/vm lain untuk bergabung ke dalam docker swarm:
+   ```bash
+   docker swarm join-token worker
+   ```
+   Setelah itu, salin output dari command tersebut.
+   <br>
+   \*Output command tersebut kurang lebih adalah seperti berikut
+   ```bash
+   docker swarm join --token SWMTKN-1-2ig... 192.168.11.74:2377
+   ```
+6. Selanjutnya, jalankan output command yang telah disalin tadi pada masing-masing pc/vm yang akan bergabung dalam jaringan menjadi docker swarm worker.
+7. Pada pc/vm docker swarm leader, jalankan command berikut untuk mengidentifikasi pc/vm yang bergabung ke dalam docker swarm:
+   ```bash
+   docker node ls
+   ```
+8. Setelah list node yang bergabung ke dalam docker swarm susah sesuai, maka selanjutnya adalah memberi nama masing-masing node yang bergabung ke dalam docker swarm. Untuk pemberian nama ini, pastikan sesuai dengan nama label yang ada dalam [docker-compose-swarm.yaml](/backend/blockchain/network/docker/docker-compose-swarm.yaml). (Contohnya dalam file docker compose, peer 1 ada constraint placement yang bernilai label lokasi pc-tengah, maka pelabelan lokasi pc/vm yang harus jadi peer 1 haruslah pc-tengah). Untuk memberi label jalankan command berikut:
+   ```bash
+   docker node update --label-add lokasi=[LABEL] <ID_NODE>
+   ```
+9. Kemudian, jalankan command berikut untuk membuat jaringan overlay yang berfungsi untuk membuat jalur komunikasi virtual agar container di pc/vm berbeda bisa saling bicara.
+   ```bash
+   docker network create --driver overlay --attachable hospital-net
+   ```
+10. Selanjutnya jalankan command berikut pada pc/vm yang berperan sebagai docker swarm leader di dalam folder yang ada [docker-compose-swarm.yaml](/backend/blockchain/network/docker/docker-compose-swarm.yaml), kalau dalam repositori ini berada dalam folder [docker](/backend/blockchain/network/docker/).
+
+    ```bash
+    docker stack deploy -c docker-compose.yaml hospital
+    ```
+
+11. Verifikasi status docker swarm dengan menjalankan command berikut pada pc/vm yang berperan sebagai docker swarm leader.
+    ```bash
+    docker service ls
+    ```
+12. Setelah jaringan berjalan, langkah selanjutnya adalah membuat channel, membuat peer dan orderer bergabung ke channel, dan melakukan deploy chaincode.
+13. Untuk membuat channel dan membuat peer dan orderer bergabung ke channel, jalankan command berikut:
+
+    ```bash
+    docker exec -it cli bash
+    ```
+
+    Setelah masuk ke dalam CLI fabric, lanjutkan dengan menjalankan command berikut:
+
+    ```bash
+    export ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/organizations/ordererOrganizations/example.com/tlsca/tlsca.example.com-cert.pem
+
+    # Buat channel
+    peer channel create -o [ip_orderer_atau_domain_orderer_sesuai_konfigurasi]:[port_orderer] -c mychannel \
+    -f ./channel-artifacts/mychannel.tx \
+    --outputBlock ./channel-artifacts/mychannel.block \
+    --tls --cafile "$ORDERER_CA"
+
+    # Export peer address
+    export CORE_PEER_ADDRESS=[ip_peer_atau_domain_peer_sesuai_konfigurasi]:[port_peer]
+    # Gabung ke dalam channel
+    peer channel join -b ./channel-artifacts/mychannel.block
+
+    # !PENTING! Jika memiliki lebih dari satu peer, peer tersebut juga
+    # harus bergabung ke dalam channel
+    export CORE_PEER_ADDRESS=[ip_peer_atau_domain_peer_sesuai_konfigurasi]:[port_peer]
+    peer channel join -b ./channel-artifacts/mychannel.block
+    ```
+
+    ### Setelah berhasil, jangan keluar dari CLI terlebih dahulu.
+
+14. Masih dalam CLI fabric, untuk melakukan deploy chaincode modifikasi dan jalankan command berikut sesuai konfigurasi jaringan anda:
+
+    ```bash
+    # Sesuaikan domain dengan peer yang digunakan, file ini dapat dilihat dalam
+    # folder organizations
+    export CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/organizations/peerOrganizations/medorg.example.com/peers/peer0.medorg.example.com/tls/server.crt
+    export CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/organizations/peerOrganizations/medorg.example.com/peers/peer0.medorg.example.com/tls/server.key
+
+    peer lifecycle chaincode package logVerification.tar.gz \
+    --path /opt/gopath/src/github.com/hyperledger/fabric/peer/chaincode/logVerification \
+    --lang golang \
+    --label logVerification_1.0
+    # Jika anda mengembangkan dan ingin mengubah versi chaincode supaya
+    # dapat mempermudah dalam hal version control, anda dapat mengubah labelnya
+    # Contoh, untuk pengembangan selanjutnya dapat menggunakan label berikut:
+    # --label logVerification_1.1
+
+    export CORE_PEER_ADDRESS=[ip_peer_atau_domain_peer_sesuai_konfigurasi]:[port_peer]
+    peer lifecycle chaincode install logVerification.tar.gz
+
+    # Install chaincode pada semua peer yang ada.
+    # Contoh, jika terdapat dua peer, maka jalankan export CORE_PEER_ADDRESS
+    # lagi dengan ip_peer untuk peer kedua.
+    export CORE_PEER_ADDRESS=[ip_peer_atau_domain_peer_kedua_sesuai_konfigurasi]:[port_peer]
+    peer lifecycle chaincode install logVerification.tar.gz
+
+    # Setelah anda menjalankan command peer lifecycle chaincode queryinstalled berikut
+    # maka akan muncul package_id chaincode anda, simpan id tersebut.
+    peer lifecycle chaincode queryinstalled
+
+    export NEW_CC_PACKAGE_ID=[isi_dari_output_command_peer_lifecycle_chaincode_queryinstalled]
+
+    peer lifecycle chaincode approveformyorg -o [ip_orderer_atau_domain_orderer_sesuai_konfigurasi]:[port_orderer] --channelID mychannel \
+    --name test-med --version [isi_dengan_versi_contoh_1.0] --package-id $CC_PACKAGE_ID --sequence [isi_dengan_sequence_ke_berapa_dan_sequence_harus_selalu_bertambah_sehingga_catat_selalu_sequence_ke_berapa] \
+    --tls --cafile "$ORDERER_CA"
+
+    # Command berikut berfungsi untuk melakukan commit chaincode.
+    # Perhatikan pada --peerAddressess, jika memiliki lebih dari satu peer
+    # sertakan juga dengan flag --peerAdressess dan format yang sesuai.
+    peer lifecycle chaincode commit -o [ip_orderer_atau_domain_orderer_sesuai_konfigurasi]:[port_orderer] --channelID mychannel \
+    --name test-med --version [isi_dengan_versi_contoh_1.0] --sequence [isi_dengan_sequence_ke_berapa_dan_sequence_harus_selalu_bertambah_sehingga_catat_selalu_sequence_ke_berapa]\
+    --collections-config /opt/gopath/src/github.com/hyperledger/fabric/peer/config/collections_config.json \
+    --tls --cafile "$ORDERER_CA" \
+    --peerAddresses [ip_peer_atau_domain_peer_sesuai_konfigurasi]:[port_peer] --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/organizations/peerOrganizations/medorg.example.com/peers/peer0.medorg.example.com/tls/ca.crt \
+    --peerAddresses [ip_peer_atau_domain_peer_sesuai_konfigurasi]:[port_peer] --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/organizations/peerOrganizations/medorg.example.com/peers/peer1.medorg.example.com/tls/ca.crt
+    ```
+

+ * 1. ISSUE - No role-based access control:
+ *    - getDashboard only uses AuthGuard
+ *    - Any authenticated user can access sensitive dashboard data
+ *    - Consider: Should regular users see tampered audit data counts?
+ *    - Fix: Add @UseGuards(RolesGuard) and @Roles(UserRole.Admin) if needed
+ *
+ * 2. ISSUE - No error handling in controller:
+ *    - Service errors propagate directly to client
+ *    - No custom error messages or status codes
+ *    - Consider: Wrap in try-catch for better error responses
+ *
+ * 3. SUGGESTION - Add caching:
+ *    - Dashboard data is likely expensive to compute
+ *    - Consider adding @CacheKey() and @CacheTTL() decorators

+/*
+ * ============================================================
+ * CODE ISSUES DOCUMENTATION
+ * ============================================================
+ *
+ * 1. ISSUE - No error handling:
+ *    - Any service error propagates directly to the controller
+ *    - No try-catch, no graceful degradation
+ *    - Fix: Wrap in try-catch, return partial data or default values
+ *
+ * 2. ISSUE - No null/undefined validation:
+ *    - Service returns whatever dependencies return
+ *    - If any dependency returns null, dashboard has null values
+ *    - Fix: Add null coalescing (value ?? defaultValue)
+ *
+ * 3. PERFORMANCE - Sequential service calls:
+ *    - All 6 service calls are awaited sequentially
+ *    - If each takes 100ms, total = 600ms
+ *    - Fix: Use Promise.all() for parallel execution
+ *
+ *    Example fix:
+ *    ```typescript
+ *    async getDashboard() {
+ *      const [
+ *        countRekamMedis,
+ *        countTindakanDokter,
+ *        countObat,
+ *        auditTrailData,
+ *        validasiData,
+ *        last7DaysRekamMedis,
+ *      ] = await Promise.all([
+ *        this.rekamMedisService.countRekamMedis(),
+ *        this.tindakanDokterService.countTindakanDokter(),
+ *        this.obatService.countObat(),
+ *        this.auditService.getCountAuditTamperedData(),
+ *        this.validationService.getAllValidationQueueDashboard(),
+ *        this.rekamMedisService.getLast7DaysCount(),
+ *      ]);
+ *      return { ... };
+ *    }
+ *    ```
+ *
+ * 4. SUGGESTION - Add response DTO:
+ *    - No type safety on return value
+ *    - Consider creating DashboardResponseDto
+ *
+ * 5. SUGGESTION - Add caching:
+ *    - Dashboard data is expensive to compute
+ *    - Consider caching with a short TTL (e.g., 30 seconds)

+# Dokumentasi mengenai Smartcontract.
+
+Smartcontract, atau dalam Fabric disebut chaincode ini dikembangkan menggunakan bahasa pemrograman Javascript. Dalam folder [logVerification](/backend/blockchain/chaincode/logVerification/), <i>source file</i> mengenai smartcontract dapat dilihat pada folder [logVerification](logVerification/). File [index.js](logVerification/index.js) berisi smartcontract yang memuat logika bisnis dalam sistem yang dikembangkan.
+
+---
+
+## Pengembangan pada smartcontract
+
+### Prasyarat
+
+- NodeJs (v20 atau lebih tinggi)
+- Hyperledger Fabric samples dan binary (v2.5.13)
+
+### Langkah pengembangan
+
+1. Pastikan NodeJs dan Fabric samples dan binary sudah terinstall.
+2. Jalankan command berikut:
+   ```bash
+   npm install
+   ```
+3. Lakukan pengembangan
+4. Untuk menjalankan hasil pengembangan, pastikan anda sudah melakukan mulai dari langkah ke-4 hingga ke-8 dalam [README.md](/README.md) pada root project.
+5. Kemudian lakukan deploy chaincode ke dalam channel seperti pada langkah ke-9 dalam [README.md](/README.md) pada root project.

+# Konfigurasi Jaringan untuk Blockchain Rekam Medis
+
+Direktori ini berisi file konfigurasi jaringan untuk jaringan blockchain Hyperledger Fabric yang digunakan dalam sistem rekam medis.
+
+## Struktur Direktori
+
+- \*`organizations/` - Berisi material kripto dan sertifikat untuk organisasi dalam jaringan
+- \*`channel-artifacts/` - Berisi artefak channel seperti genesis block dan transaksi
+- `docker/` - File Docker compose untuk konfigurasi deployment jaringan
+- `config/` - File konfigurasi jaringan
+
+**\*Jika sudah menjalankan generate artifact**
+
+## Prasyarat
+
+- Git
+- WSL2 (jika menjalankan melalui sistem operasi Windows)
+- Docker dan Docker Compose
+- Hyperledger Fabric samples dan binary (v2.5.13)
+
+## Petunjuk Instalasi dan Konfigurasi
+
+1. Pastikan anda telah menginstal Docker, Docker Compose, dan [Hyperledger Fabric](https://hyperledger-fabric.readthedocs.io/en/release-2.5/install.html).
+2. Sebelum membuat artefak jaringan, sesuaikan topologi jaringan dengan kebutuhan. Hal ini terkait dengan:
+   - Jumlah Peer dan Orderer: edit file [network/config/crypto-config.yaml](config/crypto-config.yaml) untuk mengubah jumlah Peer atau Orderer yang akan dibuat.
+   - Channel: edit file [network/config/configtx.yaml](config/configtx.yaml) untuk menyesuaikan profil channel atau menambahkan organisasi baru.
+3. Jalankan skrip `generate-artifacts.sh` pada folder [blockchain](/backend/blockchain/) untuk menghasilkan artefak jaringan:
+   ```bash
+   ./generate-artifacts.sh
+   ```
+4. Skrip di atas akan menghasilkan artefak jaringan yang diperlukan, termasuk material kripto dan sertifikat untuk organisasi. Hasilnya adalah dua folder sebagai berikut:
+   - `organizations/` - Berisi material kripto untuk organisasi
+   - `channel-artifacts/` - Berisi artefak channel seperti genesis block dan transaksi
+5. Jika menjalankan node pada beberapa VM yang berbeda, distribusikan artefak jaringan yang telah dibuat.
+   - Arsipkan artefak jaringan dengan menjalankan command
+     ```bash
+     tar -czvf artifacts.tar.gz ./network/organizations ./network/channel-artifacts
+     ```
+   - Setelah didistribusikan pada VM yang lain, ekstrak arsip tersebut.
+6. Selanjutnya adalah melakukan konfigurasi environment yang akan digunakan oleh sistem ini. Anda dapat menduplikat file `.env.example` yang berada dalam directory [docker](docker/) menjadi `.env` dan mengedit sesuai dengan petunjuk yang ada dalam file .env tersebut.
+7. Sesuaikan isi dari [docker-compose-swarm.yaml](docker/docker-compose-swarm.yaml) dengan konfigurasi node milik anda.
+8. Ubah isi dari masing-masing file konfigurasi kontainer docker sesuai petunjuk dalam file tersebut.
+9. Setelah selesai, lanjut menuju direktori [chaincode](/backend/blockchain/chaincode/) jika ingin melakukan pengembangan terkait dengan chaincode/smartcontract.
