The rapid growth of digital services, especially AI-generated content (AIGC), has driven unprecedented demand for computing power, necessitating continuous advancements in hardware, software, infrastructure, and architecture. To manage tasks efficiently, data-rich regions focus on collection and storage, while regions with abundant computing power handle processing. However, companies struggle to find flexible, cost-effective computing services, and suppliers face challenges connecting with demanders, leading to inefficient resource use. Key issues include mismatched trading, labor-intensive partnerships, and complex service delivery. Mismatched trading, due to tightly coupled demand and supply, increases costs from information asymmetry. Labor-intensive processes suffer from a skilled workforce shortage, hindering effective management and innovation. Complex delivery systems face integration challenges. This paper proposes Trustworthy Computing Transaction Services (TCTS) using blockchain and AI to dynamically match demanders and suppliers, ensuring secure, transparent transactions. TCTS automates business processes, streamlines transactions, and enhances collaboration by orchestrating computing, network, and service capabilities on a unified platform.
