Evaluating ChatGPT-4o's Performance in Creating Python Smart Contracts for Xian Blockchain

Introduction

The intersection of artificial intelligence and blockchain technology is creating exciting opportunities for developers. With the introduction of ChatGPT-4o, AI-driven coding assistance has reached new levels of sophistication. But how well does this cutting-edge AI perform when tasked with building Python smart contracts for an innovative blockchain like Xian?

This article explores how effectively ChatGPT-4o can generate, debug, and optimize Python smart contracts on the Xian Blockchain. We’ll dive into the AI's strengths, areas for improvement, and provide real-world examples of contracts generated by ChatGPT-4o.

1. Methodology: How We Tested ChatGPT-4o

To assess ChatGPT-4o’s effectiveness in creating Xian smart contracts, we conducted a series of tests:

1. Basic Smart Contract Creation: Generating a simple contract with basic functionality.
2. Advanced Contract Logic: Writing contracts with more complex logic, such as staking or voting mechanisms.
3. Error Detection and Debugging: Testing ChatGPT-4o’s ability to identify and fix errors.
4. Optimization and Best Practices: Evaluating how well the AI adheres to security and efficiency best practices specific to Xian.

2. Basic Contract Creation: A First Look

We began by asking ChatGPT-4o to write a simple greeting contract:

Prompt:

"Write a basic Xian Blockchain smart contract in Python that returns a personalized greeting."

Generated Code:

@export
def greet(name: str):
    return f"Hello, {name}! Welcome to Xian Blockchain."

Result:

• ✅ Correct Syntax: The AI correctly used Xian’s @export decorator.
• ✅ Accurate Functionality: The contract worked as intended, returning a personalized greeting.
• ✅ Efficient Code: The logic was concise and clear.

Verdict: ChatGPT-4o handled this basic task flawlessly, demonstrating its ability to generate simple contracts quickly and accurately.

3. Advanced Logic: Creating a Staking Contract

Next, we challenged ChatGPT-4o to create a more complex staking contract:

Prompt:

"Write a Python staking smart contract for Xian Blockchain that lets users deposit tokens and earn rewards."

Generated Code:

staked_balances = Hash(default_value=0)
stake_timestamps = Hash(default_value=0)
reward_rate = Variable()

@construct
def initialize(initial_reward_rate: float):
    reward_rate.set(initial_reward_rate)

@export
def stake(amount: float):
    assert amount > 0, "Amount must be greater than zero"
    staked_balances[ctx.caller] += amount
    stake_timestamps[ctx.caller] = now()

@export
def withdraw():
    amount = staked_balances[ctx.caller]
    assert amount > 0, "No tokens to withdraw"
    duration = now() - stake_timestamps[ctx.caller]
    reward = amount * reward_rate.get() * (duration / 86400)  # Daily rewards
    staked_balances[ctx.caller] = 0
    return amount + reward

Result:

• ✅ Accurate Logic: Proper staking, withdrawal, and reward calculations.
• ⚠️ Missing Knowledge about Tokens: Ignored the actual transfer of tokens using either static import or importlib.
• ⚠️ Missing Knowledge about Global Variables: now is not a function but a built-in variable containing a datetime.datetime type.
• ✅ Correct Syntax: Followed Xian’s contract structure.

Verdict: While the staking logic was sound, ChatGPT-4o overlooked essential token logic, an area for improvement when dealing with complex logic.

4. Debugging and Optimization Performance

We tested ChatGPT-4o’s debugging skills by intentionally introducing a bug:

Buggy Contract Snippet:

@export
def divide(a: int, b: int):
    return a / b

Prompt:

"Find and fix the issue with this contract."

AI-Generated Fix:

@export
def divide(a: int, b: int):
    assert b != 0, "Cannot divide by zero"
    return a / b

Result:

• ✅ Error Detection: Correctly identified the division by zero issue.
• ✅ Efficient Fix: Added an assert statement for input validation.

Verdict: ChatGPT-4o effectively handled basic debugging tasks, proving useful for catching common logic errors.

---

5. Security and Best Practices: How Well Does It Perform?

We tested ChatGPT-4o’s ability to follow Xian-specific security practices, focusing on:

• ✅ Access Control Implementation: Accurately applied access controls using ctx.caller.
• ⚠️ Does not know about already deployed contracts
• ✅ Input Validation: Consistently validated inputs using assertions.

Verdict: While ChatGPT-4o performed well on basic security measures, it needs improvement when handling external contracts specific to blockchain environments.

6. Overall Performance Analysis

Test Category	Result
Basic Contract Creation	✅ Excellent
Advanced Logic Handling	⚠️ Good, but missed the existence of the currency contract
Debugging and Error Detection	✅ Effective
Security Best Practices	✅ Good
Code Optimization	✅ Efficient and concise

Overall Verdict: ChatGPT-4o is a powerful tool for rapidly developing Python smart contracts on the Xian Blockchain. It handles basic logic exceptionally well but requires human oversight for advanced security and optimization.

Conclusion: How Useful Is ChatGPT-4o for Xian Developers?

ChatGPT-4o is an incredibly helpful assistant for developers building smart contracts on Xian:

• ✅ Speeds Up Development: Quickly generates basic contract logic and functions.
• ✅ Great for Prototyping: Ideal for generating quick prototypes and testing ideas.
• ⚠️ Requires Human Oversight: Developers should manually review advanced contracts for security and logic flaws.

Final Thought: If you’re a Python developer working on Xian Blockchain, ChatGPT-4o can be your go-to tool for fast and efficient contract development—but it’s not a complete replacement for a thorough code review.
