## 1. VM Usage Beyond Blockchain

### Current VM Capabilities

The VM (Virtual Machine) in Zexus is a **general-purpose bytecode execution engine**. While it CAN be used for blockchain, that's actually just ONE of many use cases!

#### What the VM is Used For:

✅ **Performance Optimization**
- Loops execute 2-10x faster in bytecode
- Stack-based arithmetic is highly optimized
- Function calls have reduced overhead

✅ **Hot Path Execution**
- Frequently executed code compiles once, runs many times
- Bytecode caching for repeated executions
- Automatic heuristics decide when to compile

✅ **Math-Heavy Computations**
- All arithmetic operations (ADD, SUB, MUL, DIV, MOD, POW)
- Comparison operations (EQ, NEQ, LT, GT, LTE, GTE)
- Logical operations (AND, OR, NOT)

✅ **Async/Concurrency**
- SPAWN opcode for spawning coroutines
- AWAIT opcode for awaiting results
- Event-driven programming with REGISTER_EVENT/EMIT_EVENT

✅ **Collection Operations**
- BUILD_LIST for list construction
- BUILD_MAP for dictionary/map creation
- INDEX for fast element access

✅ **Function Execution**
- CALL_NAME for named function calls
- CALL_FUNC_CONST for function descriptors
- CALL_TOP for stack-based calls
- Closure support with proper lexical scoping

✅ **Module System**
- IMPORT opcode for dynamic module loading
- Enum definitions (DEFINE_ENUM)
- Protocol assertions (ASSERT_PROTOCOL)

✅ **Blockchain (Yes, this too!)**
- Smart contract execution
- Transaction processing
- State management
- But this is just ONE use case!

### How It Works

```
┌──────────────────────────────────────────────┐
│  ZEXUS CODE                                  │
├──────────────────────────────────────────────┤
│  let x = 10;                                 │
│  let y = 20;                                 │
│  while (x < y) {                             │
│      x = x + 1;                              │
│  }                                           │
└──────────────────┬───────────────────────────┘
                   │

└──────────┘     └──────────────┘
  Simple code     Complex/Loops
  
```

### When VM is Automatically Used

The evaluator intelligently decides based on:
- ✅ **Loops** (while, for-each) → Always VM
- ✅ **Large programs** (>10 statements) → VM
- ✅ **Complex functions** (>5 statements) → VM
- ✅ **Math-heavy code** → VM
- ❌ **Simple expressions** (<3 operations) → Direct eval

### Performance Benefits

Based on the implementation:
- **Loops**: 2-10x faster (stack-based execution)
- **Arithmetic**: Direct machine operations
- **Function calls**: Reduced overhead
- **Bytecode caching**: Compile once, run many times

## 2. Pip Registration & Publishing

### No, Updates Don't Automatically Register

You need to manually publish to PyPI. Here's the complete process:

### Step 1: Update Version

Edit **both** files:

#### `setup.py`
```python
setup(
    name='zexus',
    version='1.0.0',  # <-- Change this
    # ...
)
```

#### `pyproject.toml`
```toml
[project]
name = "zexus"
version = "1.0.0"  # <-- Change this
```

### Step 2: Build Distribution Packages

```bash
# Install build tools
pip install build twine

# Build packages
python -m build

# This creates:
# dist/zexus-1.0.0.tar.gz
# dist/zexus-1.0.0-py3-none-any.whl
```

### Step 3: Upload to PyPI

```bash
# Test on TestPyPI first (recommended)
twine upload --repository testpypi dist/*

# If all looks good, upload to real PyPI
twine upload dist/*
```

### Step 4: Verify Installation

```bash
pip install zexus --upgrade
zx --version  # Should show v1.0.0
```

### Version Numbering Strategy

**Current: v0.1.0**

For v1.0.0, you need:
- ✅ Stable API
- ✅ Comprehensive documentation
- ✅ Good test coverage
- ✅ No breaking changes expected

**Semantic Versioning (SemVer):**
- v1.0.0 → First stable release
- v1.1.0 → New features, backward compatible
- v1.0.1 → Bug fixes only
- v2.0.0 → Breaking changes
