币界网报道：On-chain AI activity has surged 86% in 2025, driven by 4.5 million daily users engaging with AI-powered blockchain applications, according to recent data. The growth reflects increasing adoption of decentralized AI tools for content creation, data analysis, and automated trading. Major protocols like Fetch.ai and SingularityNET have seen user bases expand over 120% year-over-year, with transaction volumes exceeding $1.2 billion monthly. Analysts attribute the boom to improved AI model efficiency on-chain and lower gas fees enabling microtransactions for AI services. The sector now accounts for 18% of all decentralized application (dApp) traffic, up from 9% in 2024. Venture funding for AI-crypto hybrids reached $780 million in Q2 2025, with institutional investors showing growing interest. However, regulators are scrutinizing data privacy aspects as more personal information gets processed by decentralized AI networks. Industry leaders predict the convergence of AI and blockchain could redefine Web3 infrastructure by 2026.
