1. What exactly is blockchain and what are its characteristics

Blockchain is computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. A new application model, it is essentially a decentralized database, which is a series of data blocks generated using cryptographic methods. Blockchain technology refers to a way for all people to participate in accounting, and its core is decentralization.

Is this series of standard definitions difficult to understand? If you use an example to explain blockchain, it is as follows:

There is a village that cooperates collectively. An accountant was set up to keep accounts, that is, who did how much work, how many things everyone bought, how much money the village earned, etc. At the end of the year, the village chief will distribute the balance to the villagers based on the recorded ledgers.

However, people are always greedy, so some people discovered that accountants were falsifying accounts and lining their own pockets. In order to avoid such a thing from happening again, after a collective discussion, everyone decided not to use accounting and let everyone take turns keeping accounts to prevent the ledger from being controlled by a single person. This is "decentralization", that is, the ledger is accessible to everyone.

Are people greedy after all? Someone decided to embezzle village public funds, but he was afraid of being discovered by others, so he destroyed part of the account book, so no one could check him. As others learned this trick, the ledger was gone and the village's public property was almost gone.

Faced with this situation, everyone held a group discussion again and decided to use a new accounting method: everyone can have their own account book, and anyone who changes the account book must be informed Other people, other people will make the same entry in their own ledger. If someone finds something wrong with the accounts, they can point it out and refuse to accept it. When the accounts are divided at the end of the year, the accounts recognized by most people will be the legal accounts. Even if someone accidentally damages his account book, he only needs to find other legal accounts to copy. This is the "transparency and security" of blockchain.

However, this requires everyone to keep accounts every day, which is too troublesome and time-consuming. So everyone held a meeting and decided to roll the dice every morning and randomly decide who is responsible for recording the accounts of the day. After checking, others can copy it to their own account books if they think there is no problem. This is the prototype of the blockchain accounting method.

2. What does blockchain mean?

1. Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, New application models of computer technologies such as encryption algorithms. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. EachThe data block contains information about a batch of Bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next guess block.

2. In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao.

3. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period and write down his recorded content. Ledger, and the contents of the ledger will be sent to all other people in the system for backup during this period. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.

3. What are the application fields of blockchain technology?

Application fields: financial field, Internet of Things and logistics field, public service field, digital copyright field, insurance field, and public welfare field.

Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

Blockchain is closely related to people’s production and life in the fields of public management, energy, transportation, etc. However, the centralized nature of these fields also brings some problems, which can be transformed with blockchain.

4. What is the technical principle of blockchain

The key points involved in blockchain technology include : Decentralized, Trustless, Collectivelymaintained, ReliableDatabase, Timestamp, AsymmetricCryptography, etc.

Blockchain technology redefines the way credit is generated in the network: in the system, participants do not need to know other people’s background information, nor do they need to rely on guarantees from third-party institutionsOr guarantee that blockchain technology ensures that the system records, transmits, and stores value transfer activities, and the final result must be credible.

(4) Extended Reading on National Firefighting Blockchain Technology

The source of the principle of blockchain technology can be summarized as a mathematical problem: the Byzantine Generals Problem. The Byzantine Generals Problem extends to Internet life, and its connotation can be summarized as: in the context of the Internet, when it is necessary to conduct value exchange activities with unfamiliar counterparties, how can people prevent themselves from being deceived by malicious saboteurs? Be confused and make wrong decisions.

The Byzantine Generals Problem is further extended to the technical field. Its connotation can be summarized as: in the absence of a trusted central node and a trusted channel, what should the various nodes distributed in the network do? Reach a consensus. Blockchain technology solves the long-known Byzantine Generals Problem by providing a way to create a consensus network without trusting individual nodes.

5. What does smart firefighting mainly refer to

Smart firefighting uses the latest technologies such as the Internet of Things, artificial intelligence, virtual reality, and mobile Internet +, combined with big data cloud computing platforms, Professional applications such as fire alarm intelligent research and judgment realize the intelligentization of urban fire protection. They are the digital foundation of smart city fire information services and an important part of the smart perception, interconnection and smart application architecture of smart cities. With the rapid development of urban construction, urban fire safety risks continue to rise. The number of high-rise, super-high-rise buildings and large-scale buildings in cities is increasing day by day, and building fire safety issues are becoming more and more prominent. There is an urgent need for fire extinguishing and rescue technology. It is necessary to improve social fire prevention and control capabilities and achieve coordinated development of fire protection work and economic and social development. Fire is fiercer than tigers, so take precautions before they happen. With the acceleration of urbanization, how to prevent fires and ensure fire safety has become a key and difficult issue in today's urban governance. Using big data, Internet of Things and other technologies to build a "smart fire protection" system can effectively integrate the forces of all parties, find out the base of fire hazards, and accelerate the construction of urban public safety and fire prevention and control systems. It has become the key to taking the initiative in fire extinguishing and disaster relief, and at the same time also Establish a powerful safeguard measure to ensure the safety of firefighters. The establishment of a knowledge base ontology in the fire protection field and a dynamic supervision and dispatch system for fire protection resources has become the cornerstone of smart fire protection.
Jiangsu Jinge Information Experts proposed that smart firefighting uses the Internet of Things, GIS applications, mobile Internet +, artificial intelligence, big data cloud information processing and other technologies to build a firefighting big data center across three different network architectures. , create a fire protection big data platform, build two practical application systems, namely daily fire prevention system and wartime fire extinguishing system, and improve five application working mechanisms, namely "big data + infrastructure, big data + police decision-making, big data + synthetic supervision" , big data + national firefighting, big data + combat command” goals. Break the information barriers between various fire protection business systems, enable fire protection information resources to more effectively connect supply and demand, and promote the transformation of fire protection work models from traditionalFrom unity to modernity, from passiveness to initiative, from singleness to comprehensiveness, and from artificial intelligence to intelligence.

6. What is blockchain_What is blockchain technology

What is blockchain

Blockchain has become very popular recently. When people talk about blockchain, they will associate it with Bitcoin. However, blockchain is a blockchain and Bitcoin is Bitcoin. The two are completely different. Although many people have heard of it Blockchain, but they don’t understand what blockchain is. What does blockchain mean?

Blockchain refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. Many people still don’t understand decentralization. Decentralization means that there is no central ledger in the blockchain. Everyone has the opportunity to participate in accounting. Everyone is the center, and everyone in the system has a ledger. When it comes to blockchain, everyone will mention Bitcoin, because blockchain is the underlying technology of Bitcoin and is mainly used in Bitcoin. Blockchain is like a large database ledger that records all transaction records. , and the updated accounting content will be sent to all system class users.

What is blockchain technology

In layman’s terms, blockchain technology is a way for all people to participate in accounting. All systems have a corresponding database. If the database is compared to an account book, then the person who keeps the accounts is very important. These databases currently keep their own accounts. For example, Alibaba is responsible for the Taobao account book, and WeChat is responsible for the accounting. The ledger is kept by Tencent. But in the blockchain system, everyone has the opportunity to participate in accounting. The system will select the person with the best and fastest accounting, record his content on the ledger, and send the content of the ledger to everyone in the system. Personal backup allows everyone to have the same ledger, ensuring that the accounting process is transparent. There is no central ledger, which greatly improves security. In the past, it was difficult for two parties who did not trust each other to conduct transactions. For the security of transactions, a third-party platform was needed, and blockchain technology solved the credit problem of user transactions. People can complete transactions without a third-party intermediary. Bitcoin The underlying technology of currency transactions uses blockchain technology, so many people associate Bitcoin with blockchain. It is precisely because Bitcoin has been very stable for many years that people pay attention to its underlying technology. People abstract the underlying technology of Bitcoin and call it blockchain technology.
