The rise of smart cities allows us to see that emerging technologies are being widely used, and a variety of emerging industries will also emerge. While building a smart city, more scenarios will also be explored. When a variety of emerging technologies are integrated in our daily life in various postures, it brings multiple functions and conveniences. The widespread application of emerging technologies has begun, and over time, more funds have been invested in smart city projects that will bring many conveniences to city residents in terms of work and life.
From smart life to ecology, blockchain has potential
The essence of smart city construction is data collection and acquisition, sharing and exchange, fusion processing, and business collaboration and intelligent services based on this. Smart cities include:
- People's livelihood services : smart medical care, smart education;
- Urban governance: smart government affairs, smart transportation, public safety;
- Industrial economy: smart Internet of things, smart industry;
- Ecological and livable: smart energy, smart new retail.
Despite the constant difficulties, it takes time to solve and wait for verification, but from these practices, we can already see the breakthroughs of blockchain + smart city, providing an important reference for future large-scale practice.
With big data as the core, CyberVein collects, stores, develops, and analyzes a huge amount of data with scattered sources, diverse formats, and types to realize data value and capitalization, discover new knowledge, create new value, and enhance new data. The new generation of information technology and service formats with advanced capabilities make smart cities "thousands of faces".
Let the city run smarter "one network governance" new order of social governance
Smart cities use new-generation information technologies such as big data, cloud computing, blockchain, artificial intelligence, and the Internet of Things to build a co-construction, co-governance and sharing mechanism that is widely participated by the government, social organizations, and the public, and intelligentize some "urban diseases" , refined, and visualized governance.
Smart cities have encountered the problem of cross-industry and cross-domain complex system interweaving, especially the opening, exchange, integration, sharing and security of data resources that are isolated and isolated due to categories, industries, departments, regions, etc., are still challenges that need to be solved urgently . Among these challenges, the existence of blockchain can solve some problems vertically.
1. Blockchain + medical
Medical data includes patient data, doctor scientific research data, hospital survey data, etc., and most of these data are private data. On the one hand, these data must ensure their safe storage, and on the other hand, they must realize data authorization and sharing. Blockchain technology The technical characteristics of decentralized and distributed storage can realize the safe storage of data, and improve the authorization strategy to ensure that there is no risk of data leakage during the sharing process.
2. Blockchain + Smart Transportation
Transportation is a chain management, in which data is constantly exchanged and management is continuously improved. Therefore, intelligent transportation, which is based on information management of traffic road network infrastructure and traffic flow, naturally coincides with the blockchain chain model.
Intelligent transportation integrates transportation infrastructure and traffic operation status through digital, networked and intelligent management, operation and maintenance and services. The technical characteristics of the blockchain, such as decentralization, peer-to-peer network, time stamp, non-tampering, consensus mechanism, and smart contracts, can solve the problem of information asymmetry and establish a trust mechanism for a decentralized platform.
3. Blockchain + IoT
Blockchain can guarantee the security of IoT devices. Traditional IoT devices are vulnerable to attacks due to issues such as permission loopholes, insecure network ports, and unencrypted information transmission. The distributed storage of blockchain technology, the consensus mechanism of node verification in the entire network, and the asymmetric encryption algorithm can greatly reduce the risk of IoT devices being attacked. The combination of blockchain and the Internet of Things can produce half the result with twice the effort. The upgrading of the Internet of Things data industry brings about the access of massive devices. In 2020, the number of machine-to-machine connections on the public network will exceed 100 million. The traditional Internet of Things communication form deployed in a small scale It has been unable to meet the information development needs of today's big cities.
Blockchain technology can solve the scale problem of the Internet of Things, especially the trust and cost problems in large-scale applications. Through multiple blockchain nodes participating in the verification of the Internet of Things system, the information in the Internet of Things is recorded in the distributed ledger , replace the role of the central cloud, and realize the interconnection of IoT devices at a lower cost.
4. Blockchain + electronic evidence storage
In addition to the application of the Internet of Things blockchain in smart cities, there is also electronic evidence storage. Similar to invoices, data transmission, electronic contracts, etc., but because the Internet is an information transmission platform, these evidences are easy to be artificially falsified, and the falsification will cause unjust, false and wrongly decided cases in the morning, especially for court judgments, which is very important for people. Said it would be an unpredictable injury. In addition to courts, there are also many systems that need to judge events through evidence, such as enterprises and TV stations, so electronic evidence storage is a very important part.
The non-tamperable and traceable features of blockchain technology can effectively solve the security problems faced by traditional certificate deposits. It mainly includes: the distributed storage of blockchain, which can realize the safe storage and efficient extraction of electronic evidence, allow multiple institutions to share electronic evidence, reduce the cost of evidence collection, improve the efficiency of collaboration, and link and exchange evidence on the chain. All evidence will be completely stored on the chain, and it will also be verified later. The time stamp mechanism of blockchain technology, the data integrity is verified by comparing the hash value during the storage and fixing of electronic evidence, and the asymmetric encryption technology is used to encrypt electronic evidence to ensure transmission security, which can fully guarantee the authenticity and security of evidence sex.
Conclusion:
my country's smart city pilots continue to increase, covering almost all provinces, municipalities, and autonomous regions across the country. And my country's smart city construction has entered the stage of people-oriented high-quality and refined construction. A smart city construction ecology centered around people has gradually formed, and a more efficient, sophisticated, and intelligent governance model has gradually matured.
According to the principle of "overall planning, co-construction and sharing", CyberVein creates a DAVE data switch of "Internet of Things, Data, and Intelligence". PISR database, DAG storage chain, Cytrix distributed computing power platform, AI federated learning and decentralized NFT issuance and auction platform can all build a "lightweight, centralized and shared" smart city brain, centering on data collaboration, technology Collaboration and business collaboration, gather multi-source heterogeneous data such as government services, city operation perception, market and social subjects, formulate unified data standards, interface specifications, and call rules, and realize cross-department and cross-industry system platform data docking. Promote the maximum discovery of data value, and further improve social productivity and operational efficiency.
