Neural networks + blockchain: a divorce or the future of technology?

Introduction

Artificial intelligence and cryptocurrencies are the two most hyped topics of recent years. When they are combined, a rattling mixture is obtained that promises a revolution. But what really works, and what is a marketing wrapper to attract investment?

Let's look at the facts without excessive enthusiasm or skepticism.

What is AI + crypto?

The intersection of AI and cryptocurrencies can occur in several directions:

1. AI for cryptocurrencies:

Using machine learning for trading, market analysis, and fraud detection.

2. Crypt for AI

Using blockchain to decentralize AI models, tokenization of computing resources.

3. AI on the blockchain

Storage and execution of AI models in decentralized networks.

It sounds futuristic, but let's look at each direction separately:

1. Trading bots and forecasting

What they promise:

ML-based bots that analyze the market and make profitable trades 24/7.

Reality:

• Trading bots really exist and are used

• Simple algorithms (arbitrage, grid bots) work, but require customization

• "Smart" ML bots are often retrained on historical data

• The crypto market is too volatile and irrational for classical models

Verdict: It works partially, but it's not a magic pill

# Example of a simple indicator for the botdef simple_moving_average(prices, period):
    return sum(prices[-period:]) / period

def trading_signal(prices):
    sma_short = simple_moving_average(prices, 10)
    sma_long = simple_moving_average(prices, 50)
    
    if sma_short > sma_long:
        return "BUY"
    elif sma_short < sma_long:
        return "SELL"
    return "HOLD"

2. Fraud detection

What they promise:

AI can analyze transactions and find suspicious patterns.

Reality:

• It works! Chainalysis, Elliptic use ML to track money laundering

• Banks and exchanges actually use such systems

• Helps find scam projects and hacked wallets

Verdict: Real and useful use case

3. Decentralized computing for AI

Projects: Render Network, Akash Network, Fetch.ai

What they promise:

Instead of renting capacity from Amazon/Google, you can rent GPUs from ordinary people for tokens.

Reality:

• The idea is good, especially with the growing demand for GPUs for AI

• Problems: latency, data security, coordination

• So far, traditional cloud providers are more convenient and reliable

• May become relevant in case of GPU deficit

Verdict: A promising idea, but still raw

4. AI agents with crypto wallets

What they promise:

Autonomous AI agents that can make transactions and interact with DeFi.

# The concept of an AI agent with a wallet class AIAgent:
    def __init__(self, wallet_address, private_key):
        self.wallet = wallet_address
        self.key = private_key
    
    def analyze_market(self):
        # AI analyzes the market
        pass
    
    def execute_trade(self, token, amount):
        # Performs a transaction based on analysis
        pass

Reality:

• Technically possible

• Risks: an autonomous agent with access to money — what could go wrong?

• It's more of a concept than a mass product

Verdict: Interesting, but high risks

Explicit bubbles

1. "AI tokens" without real AI

Many projects add "AI" to the title, but there is no machine learning inside:

• Just use the ChatGPT API

• The usual if-else code is called the "AI algorithm"

• They promise future AI features that will never happen

🚩 Red flags:

• The whitepaper is full of buzzwords, but without technical details

• Team with no ML experience

• "Revolutionary AI technology" without open source

2. "Neural network will predict the price of bitcoin"

Truth: No neural network can reliably predict the price of cryptocurrencies.

Why:

• The market depends on news, tweets, regulations

• Historical data do not help to predict irrational behavior

• If it worked, everyone would be a millionaire

3. "Fully decentralized AI on the blockchain"

Problems:

• Blockchain is slow, AI requires fast computing

• Launching GPT-4 on Ethereum will cost millions of dollars in gas

• Confidentiality: data in the public blockchain is visible to everyone

• 

What really makes sense?

1. Blockchain analytics

AI is great at analyzing big data:

• Tracking large transactions (whale movements)

• Analysis of social sentiment

• Address clustering

• Forecasting network activity

2. DeFi Optimization

• Search for the best yield farming opportunities

• Automatic portfolio rebalancing

• Gas optimization for transactions

# Example of finding the best biddef find_best_yield(protocols, amount):
    best_apy = 0
    best_protocol = None
    
    for protocol in protocols:
        apy = protocol.get_apy()
        risk = protocol.get_risk_score()
        
        adjusted_apy = apy * (1 - risk)
        
        if adjusted_apy > best_apy:
            best_apy = adjusted_apy
            best_protocol = protocol
    
    return best_protocol

3. NFT and generative AI

• AI-generated art for NFT (it really works)

• Personalized NFTs based on user data

• Dynamic NFTs that change with AI

Code examples to get started

Receiving data from the exchange:

import ccxt
import pandas as pd

# Connecting to Binance
exchange = ccxt.binance()

# Getting historical data
ohlcv = exchange.fetch_ohlcv('BTC/USDT', '1h', limit=100)

# Convert to DataFrame
df = pd.DataFrame(ohlcv, columns=['timestamp', 'open', 'high', 'low', 'close', 'volume'])
df['timestamp'] = pd.to_datetime(df['timestamp'], unit='ms')

print(df.head())

Simple sentiment analysis:

from textblob import TextBlob
import tweepy

def analyze_crypto_sentiment(tweets):
    sentiments = []
    
    for tweet in tweets:
        analysis = TextBlob(tweet.text)
        sentiments.append(analysis.sentiment.polarity)
    
    avg_sentiment = sum(sentiments) / len(sentiments)
    
    if avg_sentiment > 0.1:
        return "POSITIVE"
    elif avg_sentiment < -0.1:
        return "NEGATIVE"
    else:
        return "NEUTRAL"

Pattern detector:

def detect_pump_and_dump(price_data, volume_data, threshold=0.2):
    """
    Simple pump & dump scheme detector
    """
    price_change = (price_data[-1] - price_data[-10]) / price_data[-10]
    volume_spike = volume_data[-1] / (sum(volume_data[-10:-1]) / 9)
    
    if price_change > threshold and volume_spike > 3:
        return "Potential pump detected!"
    
    return "Normal trading"

The future: what awaits AI + crypto?

Conclusion

AI + crypto is neither a bubble nor a revolution. It's a slow evolution.

The main thing is a critical approach and understanding of technology. Don't chase hype, build real products.
