The prosperity of the low-altitude ecology has continuously promoted the transformation of intelligent network services from the terrestrial to the low-altitude airspace.Low-altitude services and applications have become large-scale,collaborative,and intelligent.These trends have put forward extreme requirements for cross-domain collaboration capabilities,processing efficiency,and the security and trustworthiness of data and operations.Low-altitude intelligent network cluster collaboration using multi-device joint computing can improve the processing efficiency of complex and large-scale tasks in low-altitude intelligent networks.However,the existing schemes still have problems such as lack of cross-domain collaboration,deficiency in security and trustworthiness,and insufficient flexibility in centralized resource scheduling.Blockchain has the characteristics of immutability,openness,transparency,and collective maintenance,which is suitable for establishing efficient collaborative trust.This paper proposes a blockchain-enhanced trustworthy collaboration architecture for low-altitude intelligent network to provide on-chain cross-domain collaborative computing and trusted status synchronization services among heterogeneous low-altitude intelligent devices.We also design a multi-level consensus protocol to ensure the security and trustworthiness during the collaborative computation process.And we further analyze the freshness of the on-chain status,and propose an on-chain state correction algorithm and an efficient cluster-forming strategy for low-altitude intelligent nodes based on a queueing model.The simulation results show that the proposed architecture and protocol can improve the overall performance in terms of collaborative processing efficiency and network resource utilization.
