At Consensus Hong Kong 2025, one of the most captivating discussions revolved around the growing convergence of artificial intelligence (AI) and blockchain technology. Key industry figures, including Clara Tsao (Founding Officer, Filecoin Foundation), Jing Sun (Co-founder, IoTeX & MachineFi Lab), and Mark Rydon (Co-founder, Aethir), delved into how decentralized technologies could democratize AI and address the trust issues surrounding centralized data control.

Decentralized AI and Data Ownership

Clara Tsao explored the geopolitical aspects of AI’s rise, noting how global powerhouses like the U.S. and China are vying for leadership in the AI race. “Trust is a big concern when it comes to data usage,” Tsao remarked, emphasizing the growing need for data ownership. She argued that “decentralized AI, where users control where their data is stored and how it’s used, is essential to address these concerns.” Leveraging blockchain’s transparency and security, decentralized AI models enable users to retain control over their data, resolving privacy and ethical dilemmas common with centralized systems.

Decentralized Infrastructure: Cloud Computing by the People, for the People

A highlight of Consensus HK 2025 was the unveiling of Aethir’s decentralized cloud infrastructure. This distributed system allows developers to access GPU resources needed for AI workloads, democratizing access to high-performance computing without massive capital investments.

“We’re building a decentralized cloud infrastructure that democratizes access to GPU resources,” Mark Rydon stated. Aethir’s platform taps into a significant number of NVIDIA H100 GPUs, providing AI startups with a scalable, affordable way to power their projects.

Real-Time Data: The IoT-Blockchain Integration

Another important trend at the conference was the integration of real-time data into blockchain systems, a crucial factor in feeding AI models with current information. Jing Sun from IoTeX explained how IoT devices are becoming increasingly vital in providing real-time data.

“Decentralized networks are exploring ways to aggregate real-time data from weather stations, flight trackers, and IoT devices to feed into AI models,” Sun remarked. This integration enhances AI’s ability to make precise predictions and automate responses in real-time. For instance, weather sensors could trigger automatic insurance payouts based on incoming data, showcasing how blockchain brings transparency to AI applications.

The Future: Decentralized AI Agents and the Rise of the Autonomous Economy

The most visionary discussion at Consensus HK 2025 focused on the role of AI agents conducting transactions on blockchain networks, interacting autonomously with one another. Panelists predicted that AI agents could eventually conduct more transactions on-chain than humans. This shift toward AI-to-AI commerce marks a groundbreaking development in blockchain and AI integration. These agents would be able to make decisions, collaborate, and execute transactions autonomously, paving the way for a future where AI systems take on complex tasks across industries such as finance and transportation.

The potential of decentralized computing and AI to reshape the digital economy is immense. By merging these technologies, a future where individuals and businesses can access AI capabilities securely, without relying on centralized tech giants, is within reach. This convergence promises a new era of transparency, trust, and accessibility in AI.
