# DeBros Network - Distributed P2P Database System

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.

## Features

- **Distributed SQL** - RQLite with Raft consensus
- **Pub/Sub Messaging** - Topic-based with automatic cleanup
- **Namespace Isolation** - Multi-tenant support
- **Secure Transport** - LibP2P + Noise/TLS encryption
- **Unified Gateway** - Single port access to all node services

## Quick Start

### Local Development

```bash
# Build the project
make build

# Start 5-node development cluster
make dev
```

The cluster automatically performs health checks before declaring success. Check the output for:

- Node unified gateway ports (6001-6005)
- IPFS API endpoints
- Olric cache server
- Example curl commands

### Stop Development Environment

```bash
make down
```

## Testing Services

After running `make dev`, test service health using these curl requests:

> **Note:** Local domains (node-1.local, etc.) require running `sudo make setup-domains` first. Alternatively, use `localhost` with port numbers.

### Node Unified Gateways

Each node is accessible via a single unified gateway port:

```bash
# Bootstrap (port 6001)
curl http://node-1.local:6001/health
curl http://node-1.local:6001/rqlite/http/db/execute -H "Content-Type: application/json" -d '{"sql":"SELECT 1"}'
curl http://node-1.local:6001/cluster/health
curl http://node-1.local:6001/ipfs/api/v0/version

# Bootstrap2 (port 6002)
curl http://node-2.local:6002/health
curl http://node-2.local:6002/rqlite/http/db/execute -H "Content-Type: application/json" -d '{"sql":"SELECT 1"}'

# Node2 (port 6003)
curl http://node-3.local:6003/health

# Node3 (port 6004)
curl http://node-4.local:6004/health

# Node4 (port 6005)
curl http://node-5.local:6005/health
```

### Main Gateway

The main gateway provides `/v1/*` routes for RQLite, pub/sub, and storage:

```bash
# Gateway health
curl http://node-1.local:6001/health

# Gateway status
curl http://node-1.local:6001/v1/status

# Network peers
curl http://node-1.local:6001/v1/network/status

# Database query
curl http://node-1.local:6001/v1/rqlite/query \
  -H "Content-Type: application/json" \
  -d '{"sql":"SELECT 1"}'

# Pub/Sub topics
curl http://node-1.local:6001/v1/pubsub/topics
```

### Direct Service Access (Debugging)

Direct access to individual service ports without unified gateway:

```bash
# RQLite HTTP (each node on its own port)
curl http://localhost:5001/db/execute -H "Content-Type: application/json" -d '{"sql":"SELECT 1"}'  # Bootstrap
curl http://localhost:5002/db/execute -H "Content-Type: application/json" -d '{"sql":"SELECT 1"}'  # Node2

# IPFS API
curl http://localhost:4501/api/v0/version  # Bootstrap IPFS
curl http://localhost:4502/api/v0/version  # Node2 IPFS

# Olric Cache
curl http://localhost:3320/stats
```

## Network Architecture

### Unified Gateway Ports

```
Bootstrap:   localhost:6001  → /rqlite/http, /rqlite/raft, /cluster, /ipfs/api
Bootstrap2:  localhost:6002  → Same routes
Node2:       localhost:6003  → Same routes
Node3:       localhost:6004  → Same routes
Node4:       localhost:6005  → Same routes
```

### Direct Service Ports (for debugging)

```
RQLite HTTP:     5001, 5002, 5003, 5004, 5005 (one per node)
RQLite Raft:     7001, 7002, 7003, 7004, 7005
IPFS API:        4501, 4502, 4503, 4504, 4505
IPFS Swarm:      4101, 4102, 4103, 4104, 4105
Cluster API:     9094, 9104, 9114, 9124, 9134
Main Gateway:    6001
Olric Cache:     3320
Anon SOCKS:      9050
```

## Troubleshooting

### Services Not Starting

```bash
# Check status
systemctl status debros-node

# View logs
journalctl -u debros-node -f

# Check log files
tail -f /home/debros/.orama/logs/node.log
```

### Port Conflicts

```bash
# Check what's using specific ports
sudo lsof -i :443   # HTTPS Gateway
sudo lsof -i :7001  # TCP/SNI Gateway
sudo lsof -i :6001  # Internal Gateway
```

### RQLite Cluster Issues

```bash
# Connect to RQLite CLI
rqlite -H localhost -p 5001

# Check cluster status
.nodes
.status
.ready

# Check consistency level
.consistency
```

### Reset Installation

```bash
# Production reset (⚠️ DESTROYS DATA)
sudo orama uninstall
sudo rm -rf /home/debros/.orama
sudo orama install
```
