The Ubiquitous IoT (UIoT) is a three-dimensional network that spans space-air-ground. It contains multiple network elements such as satellites, terrestrial cellular networks, terrestrial gateways, and data centers. Due to the need for openness and sharing among different operators, it is necessary to research wireless spectrum sharing. The new technologies of blockchain and the 6G hybrid cloud pose a potential solution. We propose to migrate the spectrum sharing system of 6G to the hybrid blockchain. Subdividing the granularity of the spectrum resources of UIoT devices in multiple dimensions can enable reliable and secure random access to a large amount of UIoT terminal data. Cloud computing and smart contract technology can effectively ensure the interconnection of massive data and the authenticity of externally perceived data.

用于 6G UIoT 网络的基于区块链的动态频谱共享

泛在物联网（UIoT）是一个跨越天-空-地的三维网络。它包含多个网络元素，如卫星、地面蜂窝网络、地面网关和数据中心。由于不同运营商之间开放共享的需要，有必要研究无线频谱共享。区块链新技术和 6G 混合云构成了一个潜在的解决方案。我们建议将 6G 的频谱共享系统迁移到混合区块链。多维度细分UIoT设备频谱资源的粒度，可以实现对大量UIoT终端数据的可靠、安全的随机访问。云计算和智能合约技术可以有效保证海量数据的互联互通和外部感知数据的真实性。
