(1) Trustless peer-to-peer communication
By leveraging blockchain, IIoT solutions enable secure, reliable communication between devices in the Internet of Things. In this model, the blockchain will handle the exchange of messages similar to financial transactions in the Bitcoin network. To enable the exchange of messages, the device will utilize a smart contract and then simulate an agreement between the two parties. For example, we can use sensors at a distance to communicate directly with the irrigation system in order to control the flow of water based on the conditions detected on the crop.

(2) Autonomous intelligent devices
The use of blockchain makes it possible to exchange data and even perform financial transactions with truly autonomous smart devices without the need for a centralized agent. This type of autonomy is possible because nodes in the blockchain network will not rely on a central governing body to verify the validity of transactions. In this case, we can envision a smart device in a manufacturing plant that can place an order to repair part of its parts without the need for manual or centralized intervention.

(3) Self-operation without centralized authorization
A fully auditable device ledger blockchain can hold an immutable history of a smart device, a feature that enables the autonomous operation of a smart device without the need for centralized authorization. This capability is essential to meet many of the compliance and regulatory requirements for IIoT applications.

IOU distributed architecture

The distributed control blockheader of the IOU chain is mainly used for intelligent parameter lists and has a built-in function of adding product model parameters. Since the IOU chain supports a multi-datalink structure, the control block header is of a dynamic mutable type, and the block size is confirmed by the built-in data blockchain purchase using the record nNumber.

The parameters are described in detail:
1. nVersion, the block version number, which will be changed during the upgrade.
2. AIParameterVersion, the version number of the AI parameter defined in this block, if the system is not currently updated
3. If the AI parameters or the new system trading model are added, the parameter version will not change.
4. hashPrevBlock, obtained from the previous block.
5. AIChainNumber, the number indicated by the AI parameter of the data blockchain.
6. HashSystemAIParameterList, this field contains the Merkle tree calculation of the current block AI parameter list. The field configuration and parameter configuration of subsequent data blocks can be adjusted through this field list, which is a typical sign that the blockchain can evolve independently.
7. HashSystemTransModelList, this field contains the list of transaction models of the current block system
Merkle tree calculations. Through this field list, the transaction model of the system can be continuously enriched, and various transaction defects can be compensated.
8. HashUserAIParameterList, this field contains the online recruitment parameter column of the current block user

IOU consensus mechanism

The value anchor of the blockchain lies in the consumption and output of the chain itself. When a blockchain chooses PoW as the consensus mechanism, the computing power consumed by each block generation will become the cornerstone of its value. In addition, in
On the IOU chain, each node has the ability to solve real-world environmental problems and provide various online recruitment services. If the nodes on the IOU chain can participate in the solution of practical problems, the entire blockchain will have realistic output value. Therefore, in order to ensure the maximization of the value of the blockchain itself, the IOU chain control chain and each data chain will choose the PoW-based consensus mechanism by default.

However, due to the obvious defects such as slow transaction speed, in the IOU chain, in addition to the initial data chain and control chain mandatory PoW, the consensus mechanism of the subsequent data chain will be designed to be modular, which can be configured through the parameters of the control chain, and can be dynamically applied to different application scenarios of public chain and private chain.

At present, the IOU chain supports PoW, POS, DPOS, BFT, etc. for the follow-up data chain consensus mechanism. The online recruitment optimization system of the IOU chain will select the appropriate consensus mechanism according to the application scenarios and transactions of the data chain itself to ensure the consistency of data obtained by each distributed node through the algorithm.

The goal of the IOU Chain is to connect AI, devices, and data with the monetary value chain of the IOU Chain together, and to make humans the real benefit of the wealth owned by devices and AI robots through smart contracts
He who. The public chain system integrates today's IOU ecology and blockchain ecology, making it possible to directly settle goods in the Internet of Things.
