Ruff Chain is an architecture that combines the Internet of Things and blockchain. It consists of a distributed operating system and an open main chain, extending the peer-to-peer network and consensus mechanism of the virtual world to the offline world, achieving the flow of information driving atomic flow. RUFF coin is the built-in virtual currency in the Ruff Chain public chain, implemented by the virtual currency contract. RUFF coin serves as the benchmark for incentives, consumption, and transactions within the Ruff Chain public chain ecosystem. The core issue that Ruff Chain aims to solve is the trusted interoperability among different IoT devices and the issue of paid interoperability. In the future, Ruff Chain will be a new underlying architecture platform based on the Internet of Things, characterized by decentralization, development, open source, and efficiency. In the ecosystem, different participants can obtain token rewards by providing resources, or consume tokens to obtain resources, and share with each other, forming an economically driven autonomous community....
