Decentralized physical infrastructure networks (DePIN) were an indispensable cornerstone for the upcoming digital society, transforming traditional infrastructure reliant on centralized control and management into a new type of infrastructure network driven by communities and autonomous governance. The deep integration of blockchain and artificial intelligence (AI) technologies played a key role in enabling this transformation. To this end, this paper first emphasized the organic combination of "AI for blockchain (AI4B)" and "blockchain for AI (B4AI)", forming a synergistic, bidirectional closed-loop circuit to construct the truly intelligent blockchains, thereby realizing a new paradigm of blockchain intelligence. Secondly, it proposed a novel technological architecture for intelligent blockchains: on one hand, embedding intelligence into every layer of traditional blockchain architecture to cultivate the blockchain intelligence ecosystem ranging from foundational intelligence to infrastructure intelligence and then to application intelligence; on the other hand, corresponding to the actual intelligent blockchain construction, artificial intelligent blockchain were built, and through their virtual-real feedback and parallel execution, the blockchain intelligence ecosystem evolved from static rule orientation to dynamic adaptive evolution. Then, it analyzed the core intelligent attributes of blockchain intelligence from the perspectives of intelligent contracts, decentralized identity, knowledge management, and autonomous governance. Lastly, it outlined the typical application scenarios of blockchain intelligence and the key challenges faced. This paper aims to actively promote the research and development of intelligent blockchains and blockchain intelligence technologies, laying the foundation for building the core infrastructure of the future digital age. |
