The intersection of AI and blockchain is creating new possibilities for trust and intelligence in decentralized systems. AI can enhance blockchain security by detecting fraudulent activities and network vulnerabilities. In turn, blockchain provides a transparent and immutable ledger for AI models and data, ensuring their integrity. By integrating with LLMs, decentralized applications (dApps) can offer more sophisticated and autonomous services, such as smart contracts that execute based on complex, real-world data analysis, paving the way for more advanced and secure Web3 solutions.
