    """
    # Create deterministic JSON string
    genesis_string = json.dumps(genesis_data, sort_keys=True, separators=(',', ':'))
    
    # Calculate SHA-256 hash
    calculated_hash = hashlib.sha256(genesis_string.encode()).hexdigest()

    """
    # Create signature data
    signature_data = f"{signer}:{message}:{chain or 'global'}"
    
    # Generate signature (simplified for demo)
    signature = hashlib.sha256(signature_data.encode()).hexdigest()
    
    # In production, this would use actual cryptographic signing
    # signature = cryptographic_sign(private_key, signature_data)
    
    return signature

def verify_genesis_signature(signer, signature, message, chain):
    """
    Verify cryptographic signature for genesis block
    """
    # Recreate signature data
    signature_data = f"{signer}:{message}:{chain or 'global'}"
    
    # Calculate expected signature

    # Verify signature match
    signature_valid = signature == expected_signature
    
    return signature_valid
```

**Signature Validation Process**:
1. **Signer Authentication**: Verify signer identity and authority
2. **Message Creation**: Create signature message with context
3. **Signature Generation**: Generate cryptographic signature
