# Emerging Technologies & Paradigms 2025

## 🌐 1. WebAssembly (WASM) - Beyond the Web

### Production Use Cases (2025)

**1. Edge Computing**
```rust
// Cloudflare Worker in WASM
#[wasm_bindgen]
pub fn analyze_requirement(requirement: &str) -> String {
    // Run requirement analysis at edge
    let analysis = perform_analysis(requirement);
    format!("Analysis: {}", analysis)
}
```

**2. Performance-Critical Features**
```typescript
// Use WASM for heavy computation
import init, { analyze_requirements } from './wasm_module.js'

async function analyzeRequirements(items: Item[]) {
    await init()
    
    // Heavy computation in WASM
    const results = analyze_requirements(JSON.stringify(items))
    return JSON.parse(results)
}
```

**3. Portable Plugins**
```go
// Load WASM plugins at runtime
type PluginHost struct {
    runtime *wasm.Runtime
}

func (ph *PluginHost) LoadPlugin(wasmPath string) error {
    module, err := ph.runtime.LoadModule(wasmPath)
    if err != nil {
        return err
    }
    
    // Execute plugin
    result, err := module.Call("analyze", requirement)
    return err
}
```

### For TraceRTM
- ✅ CLI analysis in WASM (portable)
- ✅ Edge functions for requirement analysis
- ✅ Browser-based analysis (offline)

## 🔗 2. Blockchain & Distributed Ledger (2025)

### When to Use
- ✅ Immutable audit trail
- ✅ Multi-party verification
- ✅ Decentralized governance
- ❌ NOT for performance-critical paths

### For TraceRTM (Optional)
```go
// Immutable requirement history
type RequirementChain struct {
    blocks []Block
}

type Block struct {
    ID          string
    PreviousID  string
    Requirement Requirement
    Timestamp   time.Time
    Hash        string
}

func (rc *RequirementChain) AddBlock(req Requirement) error {
    block := Block{
        ID:          uuid.New().String(),
        PreviousID:  rc.blocks[len(rc.blocks)-1].ID,
        Requirement: req,
        Timestamp:   time.Now(),
    }
    
    block.Hash = rc.calculateHash(block)
    rc.blocks = append(rc.blocks, block)
    return nil
}
```

## 🤖 3. Quantum Computing (2025 Horizon)

### Current State
- Still experimental
- Not production-ready
- Focus on cryptography implications

### For TraceRTM
- ⚠️ Monitor quantum-safe cryptography
- ⚠️ Plan for post-quantum migration
- ⚠️ Use quantum-resistant algorithms

## 🎮 4. Spatial Computing & AR/VR

### Emerging Use Cases
- 3D requirement visualization
- Immersive collaboration
- Spatial data representation

### For TraceRTM (Future)
```typescript
// 3D requirement graph visualization
import * as THREE from 'three'

class RequirementGraph3D {
    scene: THREE.Scene
    
    visualizeRequirements(items: Item[], links: Link[]) {
        // Create 3D nodes for requirements
        items.forEach(item => {
            const geometry = new THREE.SphereGeometry(1, 32, 32)
            const material = new THREE.MeshBasicMaterial({color: 0x00ff00})
            const sphere = new THREE.Mesh(geometry, material)
            this.scene.add(sphere)
        })
        
        // Create edges for links
        links.forEach(link => {
            const geometry = new THREE.BufferGeometry()
            // ... create line between nodes
        })
    }
}
```

## 🔬 5. Advanced Data Structures (2025)

### Bloom Filters (Fast Membership Testing)
```go
// Check if requirement exists without full lookup
type BloomFilter struct {
    bits []bool
    size int
}

func (bf *BloomFilter) Add(item string) {
    for _, hash := range bf.getHashes(item) {
        bf.bits[hash%bf.size] = true
    }
}

func (bf *BloomFilter) Contains(item string) bool {
    for _, hash := range bf.getHashes(item) {
        if !bf.bits[hash%bf.size] {
            return false
        }
    }
    return true
}
```

### HyperLogLog (Cardinality Estimation)
```go
// Estimate unique requirements without storing all
type HyperLogLog struct {
    registers []byte
}

func (hll *HyperLogLog) Add(item string) {
    hash := hll.hash(item)
    register := hash % uint32(len(hll.registers))
    hll.registers[register] = hll.leadingZeros(hash)
}

func (hll *HyperLogLog) Cardinality() uint64 {
    // Estimate unique items
    return hll.estimate()
}
```

## 🌍 6. Decentralized & P2P (2025)

### IPFS for Distributed Storage
```go
// Store requirement documents on IPFS
type IPFSClient struct {
    client *ipfs.Client
}

func (ic *IPFSClient) StoreRequirement(req Requirement) (string, error) {
    data, _ := json.Marshal(req)
    
    // Add to IPFS
    cid, err := ic.client.Add(data)
    if err != nil {
        return "", err
    }
    
    return cid.String(), nil
}
```

### Libp2p for P2P Communication
```go
// Direct peer-to-peer requirement sharing
type P2PNode struct {
    host libp2p.Host
}

func (pn *P2PNode) ShareRequirement(peerID string, req Requirement) error {
    stream, err := pn.host.NewStream(context.Background(), peerID, "/tracertm/1.0.0")
    if err != nil {
        return err
    }
    
    data, _ := json.Marshal(req)
    _, err = stream.Write(data)
    return err
}
```

## 🎯 7. AI-Powered Development (2025)

### GitHub Copilot Integration
```go
// Auto-generate requirement handlers
// Copilot suggests:
func (h *Handler) CreateRequirement(c echo.Context) error {
    var req CreateRequirementRequest
    if err := c.BindJSON(&req); err != nil {
        return c.JSON(400, err)
    }
    
    // Copilot generates validation, DB call, response
    // ...
}
```

### Code Generation from Requirements
```python
# Generate code from requirement descriptions
class CodeGenerator:
    def generate_from_requirement(self, requirement: str) -> str:
        # Use Claude to generate code
        prompt = f"""
        Generate Go code for this requirement:
        {requirement}
        
        Return only the code, no explanation.
        """
        
        code = self.llm.generate(prompt)
        return code
```
