Ubique Chain of Things is a structured ecosystem that combines the latest blockchain technology and 5G chip communication solutions, designed for the next generation of smart IoT platforms, and solves the authentication in the supply chain and the Internet of Things It can help enterprises deal with the challenges of product traceability, device verification and authorization, and help protect the network while eliminating dependence on centralized management. Ubique Chain of Things can enable different companies and users on the same supply chain to improve tamper resistance and interoperability between supply chain nodes to improve efficiency, reduce operating costs, strengthen authentication, and protect data privacy.

UCOT can improve efficiency, reduce operating costs, and strengthen authentication and data privacy capabilities for different companies and customers in the same supply chain by improving tamper protection and interoperability among nodes throughout the supply chain.
The large amount of real-time data created in the UCOT ecosystem will also be used by various UCOT applications.
The vision of the UCOT team is to build the best ecosystem that enables supply chain management and smart IoT systems with automated value transfer and the most efficient process for device-to-device control.

Technical Highlights

UCOT system technology architecture consists of three layers from bottom to top, IoT layer, blockchain layer and service layer, as shown in the figure.

1. IoT layer
The secure IoT platform is the core part of the IoT layer, including the following devices:

a. Connect to performance-limited embedded tracking devices for goods throughout the supply chain

b. Fixed high-power nodes, such as video surveillance cameras

c. Mobile devices with supply chain applications

The Internet of Things platform can realize supply chain tracking and product traceability. In the IoT layer, as shown in the figure above, the applications running on lightweight embedded
devices and mobile devices are kept as simple as possible to be able to run on devices with limited resources.
Lightweight embedded devices and mobile devices upload data to the blockchain network through gateways. Specifically, applications on lightweight
embedded devices can automatically recognize the environment and upload data, while applications on lightweight mobile devices provide a manual update interface. The application signs the collected data using authentication algorithm asymmetric encryption
to ensure tamper-proof.

The gateway in the IoT layer is shown in the figure above, responsible for protocol conversion, account management, device management and its security.

a. The gateway provides an interface to convert different kinds of communication protocols (such as UDP and CoAP in NB-IoT devices) to the blockchain network by sending transactions.

b. The gateway needs to implement account and device management. In device management, lightweight devices need to be authorized first to upload data to the blockchain network. This component is designed for the situation where a specific user configures an end device with an account in the blockchain system. The configuration process is also recorded in the blockchain system. The identity mark of the terminal device corresponds to the account in the blockchain. The system is managed by accounts, not terminal devices. Account management is for devices that have accounts in the blockchain network. These devices are able to upload data directly to the blockchain network in the form of transactions.

c. At the same time, the gateway ensures security and resists attacks such as denial of service and remote intrusion. With the help of gateways, the system can support new devices and protocols without affecting the blockchain core network.

2. Blockchain layer
The blockchain layer provides all participants in the supply chain with a secure and accessible digital ledger, executes smart contracts and completes payments. We will build a blockchain-powered IoT platform that will revolutionize the entire supply chain. Smart contracts built on top of the platform will enable fast payments related to supply chain flows.

Combining blockchain with IoT will revolutionize supply chains and the entire lifecycle of applications, contributing to further developments. For example, temperature, light sensors can utilize private/consortium chains to ensure the real-time status of goods or food; using smart contracts to exchange insurance and maintenance services can provide real-time information on any product.

3. Service Layer
We provide services through backend database, frontend web interface and mobile application. Distributed databases can be used to manage supply chain data. At the same time, we will conduct user account management and data access control, so that digital information along the supply chain is shared among all participants in a trustless manner.

Web sites and applications on mobile devices provide services to businesses and users through user interfaces. This part can be adjusted according to business needs. Specifically, the service layer implements distributed databases, identity (ID) management services, blockchain content access services, token services, data request services, data sharing services, and tracking services, etc.
This layer provides two data types with different types of access:

a. Public data storage: data is fully recorded in the public blockchain, such as user configurations/requirements

b. Shared blockchain records: Data belongs to a specific group of users and is not open to other users. Requires specific access controls
