币界网报道：On-chain AI activity has surged 86% in 2025, driven by significant user growth across decentralized AI platforms, according to recent data. The expansion is attributed to increasing adoption of AI-powered decentralized applications (dApps) and the integration of blockchain technology in AI model training and data verification. Major platforms like Bittensor and Fetch.ai reported record transaction volumes, with Bittensor's TAO token seeing a 120% increase in staking activity. Analysts highlight the growing demand for transparent, decentralized AI solutions as a key factor, particularly in data privacy and model governance. The sector's rapid growth has also attracted venture capital, with over $500 million invested in AI-focused blockchain projects this year. Industry experts predict this trend will continue as more enterprises explore hybrid AI-blockchain solutions for secure, verifiable machine learning processes.
