Blockchain is a new application mode of computer technology such as distributed data storage, p2p transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm for realizing trust and acquiring rights between different nodes in the blockchain system. The Internet delivers information, and the blockchain delivers value.
In a narrow sense, a blockchain is a chained data structure in which data blocks are sequentially connected in a chronological order, and cryptographically guaranteed non-tamperable and unforgeable distributed ledgers.
Broadly speaking, blockchain technology uses blockchain data structures to validate and store data, use distributed node consensus algorithms to generate and update data, and use cryptography to ensure data transmission and access security, using automated scripts. The code consists of a smart contract to program and manipulate data in a completely new distributed infrastructure and computing paradigm.
When the car meets the blockchain, the smart car is full of imagination. Song Shijun, who is also the head of the cloud Shanghai team, said that he will also focus on exploring and experimenting with the application of blockchain in the automotive field. With the gradual improvement of the blockchain technology of Yilai Cloud in 2018, more blockchain application points will be gradually added on the basis of this project. such as:
1. User identification.
As mentioned earlier, intelligence must be based on the identification of people, only to distinguish who is who can serve good people, and will not reveal personal privacy. Then the next stage Elastos ID service chain will be used in the automotive field, allowing users to use car rental, playing, driving and other services with the blockchain ID. The identity of the user, anti-masquerading and confession are identified by the ID to ensure the safety of the vehicle.
2. Data security and authorization.
A large amount of data is generated during the use of the car, and based on this data, different commercial values ​​can be extracted. One case is to record the driving situation of the vehicle through a driving record box, and then calculate the discount of the auto insurance premium according to the driving habits. But this device needs to rely on physical methods to ensure that it is not "black" and not falsified. If you can combine the blockchain, you can store the data more conveniently, without worrying about tampering. At the same time, the data is no longer a manufacturer of the driving record box, but belongs to the user, the user can authorize one or more insurance companies to read the data, so that the data owner really enjoys the data.
3. Supply chain finance.
The automobile production process is a process of heavy assets and large capital occupation. If you can connect from the reservation to the car through the blockchain, you may be able to reduce the financial pressure on each link of the chain. for example,
The user obtains a license for the purchase of a vehicle through a bank loan and registers the chain;
The user subscribes to the new car and registers the chain;
The car company places a purchase order with the supplier according to the car order and registers the winding;
The supplier then purchases the raw materials according to the purchase order and registers the winding;
Raw material suppliers provide materials and register on the chain;
Completion of production, car companies to deliver new cars to users, registration on the chain;
The bank will pay the remaining amount to the car company and all levels of suppliers, registering the chain;
Any part of the whole link can apply for financing loan mortgages based on the order/purchase order recorded on the blockchain; even the claims of the order/purchase order can be directly traded, transferred, and credited. The blockchain makes the entire supply chain transparent and credible, reduces credit costs, improves credit ratings, and allows the economy to spin faster and more efficiently.
4. Sharing a car
Sharing bicycles, sharing rooms, and sharing cars are all seen as a crowdfunding. Multiple users work together to buy an item and then use it in turn. The emergence of the Internet helps us quickly find a group of people with common needs and preferences, so that everyone can share the cost.
It can be imagined that when the 20 people want to rent a car, each person subscribes to the car manufacturer for a car rental certificate. After the car factory receives the fundraising, it produces an autonomous car to the market. This car can automatically serve all users who hold warrants. Of course, there are more than one such car in this market, and there may be many cars. When a certain scale is reached, similar to the scale of Evcard, it is convenient for all licensed users to rent a car. If a user wants to quit, he can also trade his car rental warrants in the market. Each transfer factory can also charge a certain fee for the repair, maintenance and renewal of the vehicle.
The car factory is only responsible for the continuous production of cars according to crowdfunding; the car relies on automatic driving software to automatically serve the users; the smart contract guarantees the rights and benefits of all participants; the right to use and ownership can also be freely circulated and transferred.
Aggregate information and people through the Internet, open up consumers, investors, and producers through blockchains, allowing information, capital, and commodities to flow at high speeds, thereby reducing costs and enabling all participants to win and share revenue.
The Guoming Information Team, which is committed to tapping into the blockchain and realizing the dream of changing the world, is committed to exploring in two areas.
First, the automotive aftermarket
Blockchain technology is still exploring application scenarios to achieve large-scale applications. Combining big data analysis, artificial intelligence, and Internet of Things/vehicle networking technologies into blockchains will be applied to the trillion-dollar automotive aftermarket segment, which will reshape the market ecosystem. .
It is envisaged that the chain consists of three independent and organic blockchains, including the basic chain, the integral chain and the pass chain. The basic chain is a coalition chain developed by optimizing and innovating Hyperledger Fabric. The pass-through chain is based on Ethereum ERC20 and is issued by Token (UTIlity Token). The point chain is a chain that we built after we optimized the Bitcoin open source code innovation.
Second, used car
The second-hand car industry has asymmetric information, no authoritative neutral institutions, unsound value assessment system, and difficulties in obtaining financial services. It has established the world's first block-based vehicle lifecycle data sharing platform, dedicated to providing industry and enterprises. Standardized data services to create national automotive industry data standards.
The system will create a digital file that cannot be tampered with for each car in a decentralized storage mode. It is committed to becoming an irreplaceable data service system for the entire industrial chain such as used car trading, auto insurance, and auto gold. First of all, it solves the problem of lack of shared data in the industry. It establishes a database based on the VIN code-based vehicle life cycle database, providing standardized data services for industries and enterprises, and building national-level automotive industry data standards.
The so-called VIN code is the abbreviation of English VehicleIdenTIficaTIon Number, which is the first information source after the automobile production is offline. It carries the information of the manufacturer, age, model, body type and code, engine code and assembly location of the vehicle. . When the vehicle is sold, it will further supplement the use of the link data, such as car repair, maintenance, insurance, annual inspection, mileage and so on. At the same time, through incentive mechanism to encourage car owners, 4s stores, insurance companies, maintenance centers and other shared vehicle information, in order to fully grasp the full life cycle of the vehicle full data.
For used cars that have already been circulated in the market, we can reach a data purchase agreement with many well-known auto trading platforms and used car dealers. The vision is to become the most authoritative comprehensive data provider and service provider for the entire industry chain in the domestic automotive industry.
“Decentralization†to create an open and transparent vehicle value assessment system. Another major contradiction associated with big data collection is "how to ensure data authenticity." In response to this suspicion, the technical logic of “decentralization†and “non-changeability†of the blockchain is just a perfect solution.
