-# C Nostr Relay Database
-
-This directory contains the SQLite database schema and initialization scripts for the C Nostr Relay implementation.
-
-## Files
-
- **`schema.sql`** - Complete database schema based on nostr-rs-relay v18
- **`init.sh`** - Database initialization script
- **`c_nostr_relay.db`** - SQLite database file (created after running init.sh)
-
-## Quick Start
-
-1. **Initialize the database:**
-   ```bash
-   cd db
-   ./init.sh
-   ```
-
-2. **Force reinitialize (removes existing database):**
-   ```bash
-   ./init.sh --force
-   ```
-
-3. **Initialize with optimization and info:**
-   ```bash
-   ./init.sh --info --optimize
-   ```
-
-## Database Schema
-
-The schema is fully compatible with the Nostr protocol and includes:
-
-### Core Tables
-
- **`event`** - Main event storage with all Nostr event data
- **`tag`** - Denormalized tag index for efficient queries
- **`user_verification`** - NIP-05 verification tracking
- **`account`** - User account management (optional)
- **`invoice`** - Lightning payment tracking (optional)
-
-### Key Features
-
- ✅ **NIP-01 compliant** - Full basic protocol support
- ✅ **Replaceable events** - Supports kinds 0, 3, 10000-19999
- ✅ **Parameterized replaceable** - Supports kinds 30000-39999 with `d` tags
- ✅ **Event deletion** - NIP-09 soft deletion with `hidden` column
- ✅ **Event expiration** - NIP-40 automatic cleanup
- ✅ **Authentication** - NIP-42 client authentication
- ✅ **NIP-05 verification** - Domain-based identity verification
- ✅ **Performance optimized** - Comprehensive indexing strategy
-
-### Schema Version
-
-Current version: **v18** (compatible with nostr-rs-relay v18)
-
-## Database Structure
-
-### Event Storage
-```sql
-CREATE TABLE event (
-    id INTEGER PRIMARY KEY,
-    event_hash BLOB NOT NULL,        -- 32-byte SHA256 hash
-    first_seen INTEGER NOT NULL,     -- relay receive timestamp
-    created_at INTEGER NOT NULL,     -- event creation timestamp
-    expires_at INTEGER,              -- NIP-40 expiration
-    author BLOB NOT NULL,            -- 32-byte pubkey
-    delegated_by BLOB,               -- NIP-26 delegator
-    kind INTEGER NOT NULL,           -- event kind
-    hidden INTEGER DEFAULT FALSE,   -- soft deletion flag
-    content TEXT NOT NULL            -- complete JSON event
-);
-```
-
-### Tag Indexing
-```sql
-CREATE TABLE tag (
-    id INTEGER PRIMARY KEY,
-    event_id INTEGER NOT NULL,
-    name TEXT,                       -- tag name ("e", "p", etc.)
-    value TEXT,                      -- tag value
-    created_at INTEGER NOT NULL,     -- denormalized for performance
-    kind INTEGER NOT NULL            -- denormalized for performance
-);
-```
-
-## Performance Features
-
-### Optimized Indexes
- **Hash-based lookups** - `event_hash_index` for O(1) event retrieval
- **Author queries** - `author_index`, `author_created_at_index`
- **Kind filtering** - `kind_index`, `kind_created_at_index`
- **Tag searching** - `tag_covering_index` for efficient tag queries
- **Composite queries** - Multi-column indexes for complex filters
-
-### Query Optimization
- **Denormalized tags** - Includes `kind` and `created_at` in tag table
- **Binary storage** - BLOBs for hex data (pubkeys, hashes)
- **WAL mode** - Write-Ahead Logging for concurrent access
- **Automatic cleanup** - Triggers for data integrity
-
-## Usage Examples
-
-### Basic Operations
-
-1. **Insert an event:**
-   ```sql
-   INSERT INTO event (event_hash, first_seen, created_at, author, kind, content)
-   VALUES (?, ?, ?, ?, ?, ?);
-   ```
-
-2. **Query by author:**
-   ```sql
-   SELECT content FROM event 
-   WHERE author = ? AND hidden != TRUE
-   ORDER BY created_at DESC;
-   ```
-
-3. **Filter by tags:**
-   ```sql
-   SELECT e.content FROM event e
-   JOIN tag t ON e.id = t.event_id
-   WHERE t.name = 'p' AND t.value = ? AND e.hidden != TRUE;
-   ```
-
-### Advanced Queries
-
-1. **Get replaceable event (latest only):**
-   ```sql
-   SELECT content FROM event
-   WHERE author = ? AND kind = ? AND hidden != TRUE
-   ORDER BY created_at DESC LIMIT 1;
-   ```
-
-2. **Tag-based filtering (NIP-01 filters):**
-   ```sql
-   SELECT e.content FROM event e
-   WHERE e.id IN (
-     SELECT t.event_id FROM tag t
-     WHERE t.name = ? AND t.value IN (?, ?, ?)
-   ) AND e.hidden != TRUE;
-   ```
-
-## Maintenance
-
-### Regular Operations
-
-1. **Check database integrity:**
-   ```bash
-   sqlite3 c_nostr_relay.db "PRAGMA integrity_check;"
-   ```
-
-2. **Optimize database:**
-   ```bash
-   sqlite3 c_nostr_relay.db "PRAGMA optimize; VACUUM; ANALYZE;"
-   ```
-
-3. **Clean expired events:**
-   ```sql
-   DELETE FROM event WHERE expires_at <= strftime('%s', 'now');
-   ```
-
-### Monitoring
-
-1. **Database size:**
-   ```bash
-   ls -lh c_nostr_relay.db
-   ```
-
-2. **Table statistics:**
-   ```sql
-   SELECT name, COUNT(*) as count FROM (
-     SELECT 'events' as name FROM event UNION ALL
-     SELECT 'tags' as name FROM tag UNION ALL
-     SELECT 'verifications' as name FROM user_verification
-   ) GROUP BY name;
-   ```
-
-## Migration Support
-
-The schema includes a migration system for future updates:
-
-```sql
-CREATE TABLE schema_info (
-    version INTEGER PRIMARY KEY,
-    applied_at INTEGER NOT NULL,
-    description TEXT
-);
-```
-
-## Security Considerations
-
-1. **Input validation** - Always validate event JSON and signatures
-2. **Rate limiting** - Implement at application level
-3. **Access control** - Use `account` table for permissions
-4. **Backup strategy** - Regular database backups recommended
-
-## Compatibility
-
- **SQLite version** - Requires SQLite 3.8.0+
- **nostr-rs-relay** - Schema compatible with v18
- **NIPs supported** - 01, 02, 05, 09, 10, 11, 26, 40, 42
- **C libraries** - Compatible with sqlite3 C API
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Database locked error:**
-   - Ensure proper connection closing in your C code
-   - Check for long-running transactions
-
-2. **Performance issues:**
-   - Run `PRAGMA optimize;` regularly
-   - Consider `VACUUM` if database grew significantly
-
-3. **Schema errors:**
-   - Verify SQLite version compatibility
-   - Check foreign key constraints
-
-### Getting Help
-
- Check the main project README for C implementation details
- Review nostr-rs-relay documentation for reference implementation
- Consult Nostr NIPs for protocol specifications
