Fenghuo Network is a decentralized large-scale data flow service grid driven by blockchain innovation technology based on publish/subscribe mode, also known as the global "supercomputer bus". Committed to creating a blockchain platform for connecting IoT devices, bringing blockchain technology to every household, industry, and business. It is a consensus mechanism that does not require additional authorization, can join or exit at any time, and relies on proof of rights PoS in untrustworthy environments. It provides multi-dimensional economic incentives, especially cloud and edge node rewards, and achieves a decentralized peer-to-peer data flow grid based on topic based publish/subscribe models. We advocate the design concept of a minimalist and lightweight architecture supported by integrated rather than complex components in FiberHome Grid, such as simplifying and tightly coupling connections, encryption, consensus, routing, distribution, storage, channels, protocols, etc., fully focusing on the core ubiquitous functions (for data flow aggregation, storage, distribution) to meet various scenario requirements, making it a key component of the embryonic form of ubiquitous computing, If this prototype is compared to a huge "super server", then the FiberHome Grid will be the key presence of a huge "secure super bus". In the concept of the Internet of Things (IoE [19]), it will play the role of a lightweight component of minimalism. We hope that this large-scale lightweight component, relying on open protocols, can achieve its specific ubiquitous computing functions....
