Blockchain is a distributed shared ledger database that has several characteristics: decentralization, openness and transparency, non-tamperability, and anonymity.
Therefore, the application of blockchain should also be based on these characteristics.
1. Internet of Vehicles
The Internet of Vehicles is a large-scale system network for wireless communication and information exchange between vehicles and X (X: vehicles, roads, pedestrians and the Internet, etc.) in accordance with agreed communication protocols and data interaction standards. , the integrated network of intelligent dynamic information services and intelligent vehicle control is a typical application of Internet of Things technology in the field of transportation systems.
Blockchain technology can be a suitable solution for the Internet of Vehicles in at least four important aspects:
1. Blockchain distributed storage features data that cannot be tampered with, such as using the vehicle VIN code as a unique account to connect to the blockchain system. Due to the non-tamperability of the blockchain, traffic violation information, vehicle failures, and on-site information of traffic accidents will be permanently recorded in the blockchain, which can solidify evidence and solve the problem of vehicle data integrity.
2. Blockchain can be accessed including auto repair and auto parts, vehicle management, car manufacturers, car rental, insurance, etc. Smart contracts can realize automatic execution of transactions. Blockchain can be used to record the complete lifeline of a vehicle.
3. For example, between vehicles and vehicles, between vehicles and people, between vehicles and service providers, etc., by sharing data information protected by the blockchain, thereby improving driving safety and the efficiency of service provider management.
4. Data generates value. Through the collection of data inside and outside the vehicle during driving by Internet of Vehicles equipment, users have their own data and can share it with third parties. (Such as second-hand trading market, insurance industry) Let honest data generate value and allow users to profit.
2. Data Transaction
Data is the most important component in the future economy dominated by the Internet and machine learning. AI algorithms analyzing data will produce many world-changing discoveries. For companies with limited data collection capabilities, data trading will be a mutually beneficial endeavor that can promote company innovation and create new revenue streams. However, due to problems such as illegal reselling of data, low information transparency, and easy tampering in the current data trading market, the scale of data trading is limited.
The decentralization, security and tamper-proof traceability of the blockchain can establish trust among participating entities and promote the sustainable and substantial growth of data transactions: data ownership, transactions and authorization scope are recorded on the blockchain, and the data Ownership can be confirmed, and refined authorization scope can regulate the use of data. At the same time, every step of data from collection to distribution can be recorded on the blockchain, making the data source traceable, thereby constraining the data source and enhancing data quality. A decentralized data trading platform based on blockchain can form a larger-scale global data trading scenario.
3. Copyright Protection
1. The distributed ledger and time stamp technology of the blockchain enable the entire network to quickly reach a consensus on the ownership of intellectual property rights and realize timely confirmation of rights. Asymmetric encryption technology is used to ensure the uniqueness of copyright, and time stamp technology guarantees the copyright owner. Complete the rights confirmation process with the most cost and efficiency to solve traditional copyright protection problems.
2. By storing transaction records on the blockchain platform, the copyright owner can encrypt the copyright content and execute the copyright transaction process through smart contracts without the intervention of other platforms, which can directly solve the problems of access, distribution and profit-making of copyright content. While making copyright transactions transparent, it also helps creators maximize their income.
3. The blockchain can be combined with existing evidence collection technology to fix the pages, pictures, records and other data where infringement occurred in real time, store the infringement data as electronic evidence in the blockchain, and synchronize it to the judicial institutions through the blockchain, directly Initiate relevant litigation to achieve rapid rights protection.
Blockchain is undoubtedly another technological revolution for mankind, and it will inevitably be accompanied by further development of finance, society, and politics. However, it is undeniable that the current development of blockchain is still in a very early stage, and there are many irregularities and immaturities. The future is bright but the road is tortuous. I just hope that everyone can always treat this new thing of blockchain with sincere enthusiasm and lasting patience.
