-A decentralized peer-to-peer data platform built in Go. Combines distributed SQL (RQLite), pub/sub messaging, and resilient peer discovery so applications can share state without central infrastructure.
+A high-performance API Gateway and distributed platform built in Go. Provides a unified HTTP/HTTPS API for distributed SQL (RQLite), distributed caching (Olric), decentralized storage (IPFS), pub/sub messaging, and serverless WebAssembly execution.
+
+**Architecture:** Modular Gateway / Edge Proxy following SOLID principles
+
+## Features
+
+- **🔐 Authentication** - Wallet signatures, API keys, JWT tokens
+- **💾 Storage** - IPFS-based decentralized file storage with encryption
+- **⚡ Cache** - Distributed cache with Olric (in-memory key-value)
+- **🗄️ Database** - RQLite distributed SQL with Raft consensus
+- **📡 Pub/Sub** - Real-time messaging via LibP2P and WebSocket
+- **⚙️ Serverless** - WebAssembly function execution with host functions
+- **🌐 HTTP Gateway** - Unified REST API with automatic HTTPS (Let's Encrypt)
+- **📦 Client SDK** - Type-safe Go SDK for all services

+## Serverless Functions (WASM)
+
+Orama supports high-performance serverless function execution using WebAssembly (WASM). Functions are isolated, secure, and can interact with network services like the distributed cache.
+
+### 1. Build Functions
+
+Functions must be compiled to WASM. We recommend using [TinyGo](https://tinygo.org/).
+
+```bash
+# Build example functions to examples/functions/bin/
+./examples/functions/build.sh
+```
+
+### 2. Deployment
+
+Deploy your compiled `.wasm` file to the network via the Gateway.
+
+```bash
+# Deploy a function
+curl -X POST http://localhost:6001/v1/functions \
+  -H "Authorization: Bearer <your_api_key>" \
+  -F "name=hello-world" \
+  -F "namespace=default" \
+  -F "wasm=@./examples/functions/bin/hello.wasm"
+```
+
+### 3. Invocation
+
+Trigger your function with a JSON payload. The function receives the payload via `stdin` and returns its response via `stdout`.
+
+```bash
+# Invoke via HTTP
+curl -X POST http://localhost:6001/v1/functions/hello-world/invoke \
+  -H "Authorization: Bearer <your_api_key>" \
+  -H "Content-Type: application/json" \
+  -d '{"name": "Developer"}'
+```
+
+### 4. Management
+
+```bash
+# List all functions in a namespace
+curl http://localhost:6001/v1/functions?namespace=default
+
+# Delete a function
+curl -X DELETE http://localhost:6001/v1/functions/hello-world?namespace=default

+## Core Components
+
+### 1. API Gateway (`pkg/gateway/`)
+
+The gateway is the main entry point for all client requests. It coordinates between various backend services.
+
+**Key Files:**
+- `gateway.go` - Core gateway struct and routing
+- `dependencies.go` - Service initialization and dependency injection
+- `lifecycle.go` - Start/stop/health lifecycle management
+- `middleware.go` - Authentication, logging, error handling
+- `routes.go` - HTTP route registration
+
+**Handler Packages:**
+- `handlers/auth/` - Authentication (JWT, API keys, wallet signatures)
+- `handlers/storage/` - IPFS storage operations
+- `handlers/cache/` - Distributed cache operations
+- `handlers/pubsub/` - Pub/sub messaging
+- `handlers/serverless/` - Serverless function deployment and execution
+
+### 2. Client SDK (`pkg/client/`)
+
+Provides a clean Go SDK for interacting with the Orama Network.
+
+**Architecture:**
+```go
+// Main client interface
+type NetworkClient interface {
+    Storage() StorageClient
+    Cache() CacheClient
+    Database() DatabaseClient
+    PubSub() PubSubClient
+    Serverless() ServerlessClient
+    Auth() AuthClient
+}
+```
+
+**Key Files:**
+- `client.go` - Main client orchestration
+- `config.go` - Client configuration
+- `storage_client.go` - IPFS storage client
+- `cache_client.go` - Olric cache client
+- `database_client.go` - RQLite database client
+- `pubsub_bridge.go` - Pub/sub messaging client
+- `transport.go` - HTTP transport layer
+- `errors.go` - Client-specific errors
+
+**Usage Example:**
+```go
+import "github.com/DeBrosOfficial/network/pkg/client"
+
+// Create client
+cfg := client.DefaultClientConfig()
+cfg.GatewayURL = "https://api.orama.network"
+cfg.APIKey = "your-api-key"
+
+c := client.NewNetworkClient(cfg)
+
+// Use storage
+resp, err := c.Storage().Upload(ctx, data, "file.txt")
+
+// Use cache
+err = c.Cache().Set(ctx, "key", value, 0)
+
+// Query database
+rows, err := c.Database().Query(ctx, "SELECT * FROM users")
+
+// Publish message
+err = c.PubSub().Publish(ctx, "chat", []byte("hello"))
+
+// Deploy function
+fn, err := c.Serverless().Deploy(ctx, def, wasmBytes)
+
+// Invoke function
+result, err := c.Serverless().Invoke(ctx, "function-name", input)
+```
+
+### 3. Database Layer (`pkg/rqlite/`)
+
+ORM-like interface over RQLite distributed SQL database.
+
+**Key Files:**
+- `client.go` - Main ORM client
+- `orm_types.go` - Interfaces (Client, Tx, Repository[T])
+- `query_builder.go` - Fluent query builder
+- `repository.go` - Generic repository pattern
+- `scanner.go` - Reflection-based row scanning
+- `transaction.go` - Transaction support
+
+**Features:**
+- Fluent query builder
+- Generic repository pattern with type safety
+- Automatic struct mapping
+- Transaction support
+- Connection pooling with retry
+
+**Example:**
+```go
+// Query builder
+users, err := client.CreateQueryBuilder("users").
+    Select("id", "name", "email").
+    Where("age > ?", 18).
+    OrderBy("name ASC").
+    Limit(10).
+    GetMany(ctx, &users)
+
+// Repository pattern
+type User struct {
+    ID    int    `db:"id"`
+    Name  string `db:"name"`
+    Email string `db:"email"`
+}
+
+repo := client.Repository("users")
+user := &User{Name: "Alice", Email: "alice@example.com"}
+err := repo.Save(ctx, user)
+```
+
+### 4. Serverless Engine (`pkg/serverless/`)
+
+WebAssembly (WASM) function execution engine with host functions.
+
+**Architecture:**
+```
+pkg/serverless/
+├── engine.go              - Core WASM engine
+├── execution/             - Function execution
+│   ├── executor.go
+│   └── lifecycle.go
+├── cache/                 - Module caching
+│   └── module_cache.go
+├── registry/              - Function metadata
+│   ├── registry.go
+│   ├── function_store.go
+│   ├── ipfs_store.go
+│   └── invocation_logger.go
+└── hostfunctions/         - Host functions by domain

+```
+
+**Features:**
+- Secure WASM execution sandbox
+- Memory and CPU limits
+- Host function injection (cache, storage, DB, HTTP)
+- Function versioning
+- Invocation logging
+- Hot module reloading
+
+### 5. Configuration System (`pkg/config/`)
+
+Domain-specific configuration with validation.
+
+**Structure:**
+```
+pkg/config/
+├── config.go              - Main config aggregator
+├── loader.go              - YAML loading
+├── node_config.go         - Node settings
+├── database_config.go     - Database settings
+├── gateway_config.go      - Gateway settings
+└── validate/              - Validation
+    ├── validators.go
+    ├── node.go
+    ├── database.go
+    └── gateway.go
+```
+
+### 6. Shared Utilities
+
+**HTTP Utilities (`pkg/httputil/`):**
+- Request parsing and validation
+- JSON response writers
+- Error handling
+- Authentication extraction
+
+**Error Handling (`pkg/errors/`):**
+- Typed errors (ValidationError, NotFoundError, etc.)
+- HTTP status code mapping
+- Error wrapping with context
+- Stack traces
+
+**Contracts (`pkg/contracts/`):**
+- Interface definitions for all services
+- Enables dependency injection
+- Clean abstractions
+
+## Data Flow
+
+### 1. HTTP Request Flow
+
+```
+Client Request
+    ↓
+[HTTPS Termination]
+    ↓
+[Authentication Middleware]
+    ↓
+[Route Handler]
+    ↓
+[Service Layer]
+    ↓
+[Backend Service] (RQLite/Olric/IPFS)
+    ↓
+[Response Formatting]
+    ↓
+Client Response
+```
+
+### 2. WebSocket Flow (Pub/Sub)
+
+```
+Client WebSocket Connect
+    ↓
+[Upgrade to WebSocket]
+    ↓
+[Authentication]
+    ↓
+[Subscribe to Topic]
+    ↓
+[LibP2P PubSub] ←→ [Local Subscribers]
+    ↓
+[Message Broadcasting]
+    ↓
+Client Receives Messages
+```
+
+### 3. Serverless Invocation Flow
+
+```
+Function Deployment:
+    Upload WASM → Store in IPFS → Save Metadata (RQLite) → Compile Module
+
+Function Invocation:
+    Request → Load Metadata → Get WASM from IPFS →
+    Execute in Sandbox → Return Result → Log Invocation
+```
+
+## Security Architecture
+
+### Authentication Methods
+
+1. **Wallet Signatures** (Ethereum-style)
+   - Challenge/response flow
+   - Nonce-based to prevent replay attacks
+   - Issues JWT tokens after verification
+
+2. **API Keys**
+   - Long-lived credentials
+   - Stored in RQLite
+   - Namespace-scoped
+
+3. **JWT Tokens**
+   - Short-lived (15 min default)
+   - Refresh token support
+   - Claims-based authorization
+
+### TLS/HTTPS
+
+- Automatic ACME (Let's Encrypt) certificate management
+- TLS 1.3 support
+- HTTP/2 enabled
+- Certificate caching
+
+### Middleware Stack
+
+1. **Logger** - Request/response logging
+2. **CORS** - Cross-origin resource sharing
+3. **Authentication** - JWT/API key validation
+4. **Authorization** - Namespace access control
+5. **Rate Limiting** - Per-client rate limits
+6. **Error Handling** - Consistent error responses
+
+## Scalability
+
+### Horizontal Scaling
+
+- **Gateway:** Stateless, can run multiple instances behind load balancer
+- **RQLite:** Multi-node cluster with Raft consensus
+- **IPFS:** Distributed storage across nodes
+- **Olric:** Distributed cache with consistent hashing
+
+### Caching Strategy
+
+1. **WASM Module Cache** - Compiled modules cached in memory
+2. **Olric Distributed Cache** - Shared cache across nodes
+3. **Local Cache** - Per-gateway request caching
+
+### High Availability
+
+- **Database:** RQLite cluster with automatic leader election
+- **Storage:** IPFS replication factor configurable
+- **Cache:** Olric replication and eventual consistency
+- **Gateway:** Stateless, multiple replicas supported
+
+## Monitoring & Observability
+
+### Health Checks
+
+- `/health` - Liveness probe
+- `/v1/status` - Detailed status with service checks
+
+### Metrics
+
+- Prometheus-compatible metrics endpoint
+- Request counts, latencies, error rates
+- Service-specific metrics (cache hit ratio, DB query times)
+
+### Logging
+
+- Structured logging (JSON format)
+- Log levels: DEBUG, INFO, WARN, ERROR
+- Correlation IDs for request tracing
+
+## Development Patterns
+
+### SOLID Principles
+
+- **Single Responsibility:** Each handler/service has one focus
+- **Open/Closed:** Interface-based design for extensibility
+- **Liskov Substitution:** All implementations conform to contracts
+- **Interface Segregation:** Small, focused interfaces
+- **Dependency Inversion:** Depend on abstractions, not implementations
+
+### Code Organization
+
+- **Average file size:** ~150 lines
+- **Package structure:** Domain-driven, feature-focused
+- **Testing:** Unit tests for logic, E2E tests for integration
+- **Documentation:** Godoc comments on all public APIs
+
+## Deployment
+
+### Development
+
+```bash
+make dev       # Start 5-node cluster
+make stop      # Stop all services
+make test      # Run unit tests
+make test-e2e  # Run E2E tests
+```
+
+### Production
+
+```bash
+# First node (creates cluster)
+sudo orama install --vps-ip <IP> --domain node1.example.com
+
+# Additional nodes (join cluster)
+sudo orama install --vps-ip <IP> --domain node2.example.com \
+    --peers /dns4/node1.example.com/tcp/4001/p2p/<PEER_ID> \
+    --join <node1-ip>:7002 \
+    --cluster-secret <secret> \
+    --swarm-key <key>
+```
+
+### Docker (Future)
+
+Planned containerization with Docker Compose and Kubernetes support.
+
+## Future Enhancements
+
+1. **GraphQL Support** - GraphQL gateway alongside REST
+2. **gRPC Support** - gRPC protocol support
+3. **Event Sourcing** - Event-driven architecture
+4. **Kubernetes Operator** - Native K8s deployment
+5. **Observability** - OpenTelemetry integration
+6. **Multi-tenancy** - Enhanced namespace isolation

+# Orama Network Client SDK
+
+## Overview
+
+The Orama Network Client SDK provides a clean, type-safe Go interface for interacting with the Orama Network. It abstracts away the complexity of HTTP requests, authentication, and error handling.
+
+## Installation
+
+```bash
+go get github.com/DeBrosOfficial/network/pkg/client
+```
+
+## Quick Start
+
+```go
+package main
+
+import (
+    "context"
+    "fmt"
+    "log"
+
+    "github.com/DeBrosOfficial/network/pkg/client"
+)
+
+func main() {
+    // Create client configuration
+    cfg := client.DefaultClientConfig()
+    cfg.GatewayURL = "https://api.orama.network"
+    cfg.APIKey = "your-api-key-here"
+
+    // Create client
+    c := client.NewNetworkClient(cfg)
+
+    // Use the client
+    ctx := context.Background()
+
+    // Upload to storage
+    data := []byte("Hello, Orama!")
+    resp, err := c.Storage().Upload(ctx, data, "hello.txt")
+    if err != nil {
+        log.Fatal(err)
+    }
+    fmt.Printf("Uploaded: CID=%s\n", resp.CID)
+}
+```
+
+## Configuration
+
+### ClientConfig
+
+```go
+type ClientConfig struct {
+    // Gateway URL (e.g., "https://api.orama.network")
+    GatewayURL string
+
+    // Authentication (choose one)
+    APIKey    string  // API key authentication
+    JWTToken  string  // JWT token authentication
+
+    // Client options
+    Timeout   time.Duration  // Request timeout (default: 30s)
+    UserAgent string         // Custom user agent
+
+    // Network client namespace
+    Namespace string  // Default namespace for operations
+}
+```
+
+### Creating a Client
+
+```go
+// Default configuration
+cfg := client.DefaultClientConfig()
+cfg.GatewayURL = "https://api.orama.network"
+cfg.APIKey = "your-api-key"
+
+c := client.NewNetworkClient(cfg)
+```
+
+## Authentication
+
+### API Key Authentication
+
+```go
+cfg := client.DefaultClientConfig()
+cfg.APIKey = "your-api-key-here"
+c := client.NewNetworkClient(cfg)
+```
+
+### JWT Token Authentication
+
+```go
+cfg := client.DefaultClientConfig()
+cfg.JWTToken = "your-jwt-token-here"
+c := client.NewNetworkClient(cfg)
+```
+
+### Obtaining Credentials
+
+```go
+// 1. Login with wallet signature (not yet implemented in SDK)
+// Use the gateway API directly: POST /v1/auth/challenge + /v1/auth/verify
+
+// 2. Issue API key after authentication
+// POST /v1/auth/apikey with JWT token
+```
+
+## Storage Client
+
+Upload, download, pin, and unpin files to IPFS.
+
+### Upload File
+
+```go
+data := []byte("Hello, World!")
+resp, err := c.Storage().Upload(ctx, data, "hello.txt")
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("CID: %s\n", resp.CID)
+```
+
+### Upload with Options
+
+```go
+opts := &client.StorageUploadOptions{
+    Pin:               true,           // Pin after upload
+    Encrypt:           true,           // Encrypt before upload
+    ReplicationFactor: 3,              // Number of replicas
+}
+resp, err := c.Storage().UploadWithOptions(ctx, data, "file.txt", opts)
+```
+
+### Get File
+
+```go
+cid := "QmXxx..."
+data, err := c.Storage().Get(ctx, cid)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Downloaded %d bytes\n", len(data))
+```
+
+### Pin File
+
+```go
+cid := "QmXxx..."
+resp, err := c.Storage().Pin(ctx, cid)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Pinned: %s\n", resp.CID)
+```
+
+### Unpin File
+
+```go
+cid := "QmXxx..."
+err := c.Storage().Unpin(ctx, cid)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Println("Unpinned successfully")
+```
+
+### Check Pin Status
+
+```go
+cid := "QmXxx..."
+status, err := c.Storage().Status(ctx, cid)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Status: %s, Replicas: %d\n", status.Status, status.Replicas)

+Distributed key-value cache using Olric.
+
+### Set Value
+
+```go
+key := "user:123"
+value := map[string]interface{}{
+    "name": "Alice",
+    "email": "alice@example.com",
+}
+ttl := 5 * time.Minute
+
+err := c.Cache().Set(ctx, key, value, ttl)
+if err != nil {
+    log.Fatal(err)
+}
+```
+
+### Get Value
+
+```go
+key := "user:123"
+var user map[string]interface{}
+err := c.Cache().Get(ctx, key, &user)
+if err != nil {

+    Email string `json:"email"`
+}
+
+var users []User
+for _, row := range rows {
+    var user User
+    // Parse row into user struct
+    // (manual parsing required, or use ORM layer)
+    users = append(users, user)
+}
+```
+
+### Create Table
+
+```go
+schema := `CREATE TABLE IF NOT EXISTS users (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,

+err := c.PubSub().Publish(ctx, topic, message)
+if err != nil {
+    log.Fatal(err)
+}
+```
+
+### Subscribe to Topic
+
+```go
+topic := "chat"
+handler := func(ctx context.Context, msg []byte) error {
+    fmt.Printf("Received: %s\n", string(msg))
+    return nil
+}
+
+unsubscribe, err := c.PubSub().Subscribe(ctx, topic, handler)
+if err != nil {
+    log.Fatal(err)
+}
+
+// Later: unsubscribe
+defer unsubscribe()
+```
+
+### List Topics

+```
+
+## Serverless Client
+
+Deploy and invoke WebAssembly functions.
+
+### Deploy Function
+
+```go
+// Read WASM file
+wasmBytes, err := os.ReadFile("function.wasm")
+if err != nil {
+    log.Fatal(err)
+}
+
+// Function definition
+def := &client.FunctionDefinition{
+    Name:        "hello-world",
+    Namespace:   "default",
+    Description: "Hello world function",
+    MemoryLimit: 64, // MB
+    Timeout:     30, // seconds
+}
+
+// Deploy
+fn, err := c.Serverless().Deploy(ctx, def, wasmBytes)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Deployed: %s (CID: %s)\n", fn.Name, fn.WASMCID)
+```
+
+### Invoke Function
+
+```go
+functionName := "hello-world"
+input := map[string]interface{}{
+    "name": "Alice",
+}
+
+output, err := c.Serverless().Invoke(ctx, functionName, input)
+if err != nil {
+    log.Fatal(err)
+}
+fmt.Printf("Result: %s\n", output)
+```
+
+### List Functions
+
+```go
+functions, err := c.Serverless().List(ctx)
+if err != nil {
+    log.Fatal(err)
+}
+for _, fn := range functions {
+    fmt.Printf("- %s: %s\n", fn.Name, fn.Description)
+}
+```
+
+### Delete Function
+
+```go
+functionName := "hello-world"
+err := c.Serverless().Delete(ctx, functionName)
+if err != nil {
+    log.Fatal(err)
+}
+```
+
+### Get Function Logs
+
+```go
+functionName := "hello-world"
+logs, err := c.Serverless().GetLogs(ctx, functionName, 100)
+if err != nil {
+    log.Fatal(err)
+}
+for _, log := range logs {
+    fmt.Printf("[%s] %s: %s\n", log.Timestamp, log.Level, log.Message)
+}
+```
+
+## Error Handling
+
+All client methods return typed errors that can be checked:
+
+```go
+import "github.com/DeBrosOfficial/network/pkg/errors"
+
+resp, err := c.Storage().Upload(ctx, data, "file.txt")
+if err != nil {
+    if errors.IsNotFound(err) {
+        fmt.Println("Resource not found")
+    } else if errors.IsUnauthorized(err) {
+        fmt.Println("Authentication failed")
+    } else if errors.IsValidation(err) {
+        fmt.Println("Validation error")
+    } else {
+        log.Fatal(err)
+    }
+}
+```
+
+## Advanced Usage
+
+### Custom Timeout
+
+```go
+ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
+defer cancel()
+
+resp, err := c.Storage().Upload(ctx, data, "file.txt")
+```
+
+### Retry Logic
+
+```go

+# Gateway API Documentation
+
+## Overview
+
+The Orama Network Gateway provides a unified HTTP/HTTPS API for all network services. It handles authentication, routing, and service coordination.
+
+**Base URL:** `https://api.orama.network` (production) or `http://localhost:6001` (development)
+
+## Authentication
+
+All API requests (except `/health` and `/v1/auth/*`) require authentication.
+
+### Authentication Methods
+
+1. **API Key** (Recommended for server-to-server)
+2. **JWT Token** (Recommended for user sessions)
+3. **Wallet Signature** (For blockchain integration)
+
+### Using API Keys
+
+Include your API key in the `Authorization` header:
+
+```bash
+curl -H "Authorization: Bearer your-api-key-here" \
+     https://api.orama.network/v1/status
+```
+
+Or in the `X-API-Key` header:
+
+```bash
+curl -H "X-API-Key: your-api-key-here" \
+     https://api.orama.network/v1/status
+```
+
+### Using JWT Tokens
+
+```bash
+curl -H "Authorization: Bearer your-jwt-token-here" \
+     https://api.orama.network/v1/status
+```
+

+- **Burst:** 200 requests
+
+Rate limit headers:
+```
+X-RateLimit-Limit: 100
+X-RateLimit-Remaining: 95
+X-RateLimit-Reset: 1611144000
+```
+
+When rate limited:
+```json
+{
+  "code": "RATE_LIMIT_EXCEEDED",
+  "message": "rate limit exceeded",
+  "details": {
+    "limit": 100,
+    "retry_after": 60
+  }

+## Services Running on Each Server
+
+| Service | Port(s) | Purpose | Public Access |
+|---------|---------|---------|---------------|
+| **orama-node** | 80, 443, 7001 | API Gateway | Yes (80, 443 only) |
+| **rqlited** | 5001, 7002 | Distributed SQLite DB | Cluster only |
+| **ipfs** | 4101, 4501, 8080 | Content-addressed storage | Cluster only |

+| **SSH** | 22 | Remote access | Yes |
+
+---
+
+## Security Measures Implemented
+
+### 1. Firewall Configuration (UFW)
+
+**Status:** ✅ Enabled on all 4 servers
+
+#### Public Ports (Open to Internet)
+- **22/tcp** - SSH (with hardening)
+- **80/tcp** - HTTP (redirects to HTTPS)
+- **443/tcp** - HTTPS (Let's Encrypt production certificates)
+- **4001/tcp** - libp2p swarm (P2P networking)
+
+#### Cluster-Only Ports (Restricted to 4 Server IPs)
+All the following ports are ONLY accessible from the 4 cluster IPs:
+- **5001/tcp** - rqlite HTTP API
+- **7001/tcp** - SNI Gateway
+- **7002/tcp** - rqlite Raft consensus
+- **9094/tcp** - IPFS Cluster API
+- **9098/tcp** - IPFS Cluster communication
+- **3322/tcp** - Olric distributed cache
+- **4101/tcp** - IPFS swarm (cluster internal)
+
+#### Firewall Rules Example
+```bash
+sudo ufw default deny incoming
+sudo ufw default allow outgoing
+sudo ufw allow 22/tcp comment "SSH"
+sudo ufw allow 80/tcp comment "HTTP"
+sudo ufw allow 443/tcp comment "HTTPS"
+sudo ufw allow 4001/tcp comment "libp2p swarm"
+
+# Cluster-only access for sensitive services
+sudo ufw allow from 51.83.128.181 to any port 5001 proto tcp
+sudo ufw allow from 194.61.28.7 to any port 5001 proto tcp
+sudo ufw allow from 83.171.248.66 to any port 5001 proto tcp
+sudo ufw allow from 62.72.44.87 to any port 5001 proto tcp
+# (repeat for ports 7001, 7002, 9094, 9098, 3322, 4101)
+
+sudo ufw enable
+```
+
+### 2. SSH Hardening
+
+**Location:** `/etc/ssh/sshd_config.d/99-hardening.conf`
+
+**Configuration:**
+```bash
+PermitRootLogin yes               # Root login allowed with SSH keys
+PasswordAuthentication yes        # Password auth enabled (you have keys configured)
+PubkeyAuthentication yes          # SSH key authentication enabled
+PermitEmptyPasswords no           # No empty passwords
+X11Forwarding no                  # X11 disabled for security
+MaxAuthTries 3                    # Max 3 login attempts
+ClientAliveInterval 300           # Keep-alive every 5 minutes
+ClientAliveCountMax 2             # Disconnect after 2 failed keep-alives
+```

+ssh root@194.61.28.7
+ssh root@83.171.248.66
+ssh root@62.72.44.87
+```
+
+**Important:** Password authentication is still enabled, but your SSH keys are configured for passwordless access.
+
+---
+
+## Testing & Verification
+
+### 1. Test External Port Access (From Your Machine)
+
+```bash
+# These should be BLOCKED (timeout or connection refused):
+nc -zv 51.83.128.181 5001   # rqlite API - should be blocked
+nc -zv 51.83.128.181 7002   # rqlite Raft - should be blocked
+nc -zv 51.83.128.181 9094   # IPFS cluster - should be blocked
+
+# These should be OPEN:
+nc -zv 51.83.128.181 22     # SSH - should succeed
+nc -zv 51.83.128.181 80     # HTTP - should succeed
+nc -zv 51.83.128.181 443    # HTTPS - should succeed
+nc -zv 51.83.128.181 4001   # libp2p - should succeed
+```
+
+### 2. Test Domain Access
+
+```bash
+curl -I https://node-kv4la8.debros.network
+curl -I https://node-7prvNa.debros.network
+curl -I https://node-xn23dq.debros.network
+curl -I https://node-nns4n5.debros.network
+```
+
+All should return `HTTP/1.1 200 OK` or similar with valid SSL certificates.
+
+### 3. Test Cluster Communication (From VPS 1)
+
+```bash
+ssh ubuntu@51.83.128.181
+# Test rqlite cluster
+curl -s http://localhost:5001/status | jq -r '.store.nodes[].id'
+
+# Test IPFS cluster
+curl -s http://localhost:9094/id | jq -r '.cluster_peers[]'
+
+# Check all services running
+ps aux | grep -E "(orama-node|rqlited|ipfs|olric)" | grep -v grep
+```
+
+---
+
+## Maintenance & Operations
+
+### Firewall Management
+
+**View current rules:**
+```bash
+sudo ufw status numbered
+```
+
+**Add a new allowed IP for cluster services:**
+```bash
+sudo ufw allow from NEW_IP_ADDRESS to any port 5001 proto tcp
+sudo ufw allow from NEW_IP_ADDRESS to any port 7002 proto tcp
+# etc.
+```
+
+**Delete a rule:**
+```bash
+sudo ufw status numbered  # Get rule number
+sudo ufw delete [NUMBER]
+```
+
+### SSH Management
+
+**Test SSH config without applying:**
+```bash
+sudo sshd -t
+```
+
+**Reload SSH after config changes:**
+```bash
+sudo systemctl reload ssh
+```
+
+**View SSH login attempts:**
+```bash
+sudo journalctl -u ssh | tail -50
+```
+
+### Fail2ban Management
+
+**Check banned IPs:**
+```bash
+sudo fail2ban-client status sshd
+```
+
+**Unban an IP:**
+```bash
+sudo fail2ban-client set sshd unbanip IP_ADDRESS
+```
+
+### Security Updates
+
+**Check for updates:**
+```bash
+apt list --upgradable
+```
+
+**Apply updates:**
+```bash
+sudo apt update && sudo apt upgrade -y
+```
+
+**Reboot if kernel updated:**
+```bash
+sudo reboot
+```
+
+---
+
+## Security Improvements Completed
+
+### Before Security Audit:
+- ❌ No firewall enabled
+- ❌ rqlite database exposed to internet (port 5001, 7002)
+- ❌ IPFS cluster management exposed (port 9094, 9098)
+- ❌ Olric cache exposed (port 3322)
+- ❌ Root login enabled without restrictions (VPS 2, 3, 4)
+- ❌ No fail2ban on 3 out of 4 servers
+- ❌ 19-39 security updates pending
+
+### After Security Hardening:
+- ✅ UFW firewall enabled on all servers
+- ✅ Sensitive ports restricted to cluster IPs only
+- ✅ SSH hardened with key authentication
+- ✅ Fail2ban protecting all servers
+- ✅ All security updates applied
+- ✅ Let's Encrypt production certificates verified
+- ✅ Cluster communication tested and working
+- ✅ External access verified (HTTP/HTTPS only)
+
+---
+
+## Recommended Next Steps (Optional)
+
+These were not implemented per your request but are recommended for future consideration:
+
+1. **VPN/Private Networking** - Use WireGuard or Tailscale for encrypted cluster communication instead of firewall rules
+2. **Automated Security Updates** - Enable unattended-upgrades for automatic security patches
+3. **Monitoring & Alerting** - Set up Prometheus/Grafana for service monitoring
+4. **Regular Security Audits** - Run `lynis` or `rkhunter` monthly for security checks
+
+---
+
+## Important Notes
+
+### Let's Encrypt Configuration
+
+The Orama Network gateway uses **autocert** from Go's `golang.org/x/crypto/acme/autocert` package. The configuration is in:
+
+**File:** `/home/debros/.orama/configs/node.yaml`
+
+**Relevant settings:**
+```yaml
+http_gateway:
+  https:
+    enabled: true
+    domain: "node-kv4la8.debros.network"
+    auto_cert: true
+    cache_dir: "/home/debros/.orama/tls-cache"
+    http_port: 80
+    https_port: 443
+    email: "admin@node-kv4la8.debros.network"
+```
+
+**Important:** There is NO `letsencrypt_staging` flag set, which means it defaults to **production Let's Encrypt**. This is correct for production deployment.
+
+### Firewall Persistence
+
+UFW rules are persistent across reboots. The firewall will automatically start on boot.
+
+### SSH Key Access
+
+Both of your SSH keys are configured on all servers. You can access:
+- VPS 1: `ssh -i ~/.ssh/ssh-sotiris/id_ed25519 ubuntu@51.83.128.181`
+- VPS 2-4: `ssh -i ~/.ssh/ssh-sotiris/id_ed25519 root@IP_ADDRESS`
+
+Password authentication is still enabled as a fallback, but keys are recommended.
+
+---
+
+## Emergency Access
+
+If you get locked out:
+
+1. **VPS Provider Console:** All major VPS providers offer web-based console access
+2. **Password Access:** Password auth is still enabled on all servers
+3. **SSH Keys:** Two keys configured for redundancy
+
+**Disable firewall temporarily (emergency only):**
+```bash
+sudo ufw disable
+# Fix the issue
+sudo ufw enable
+```
+
+---
+
+## Verification Checklist
