哪个不是区块链技术的特点,哪个不是区块链技术的特点之一

Ⅰ Characteristics of blockchain technology include

The four major characteristics of blockchain technology include: decentralization; trustlessness; scalability; anonymity. The decentralized nature of blockchain is a highly controversial and sensitive issue.
Blockchain technology (BT) uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure the security of data transmission and access. , a new distributed infrastructure and computing paradigm that uses smart contracts composed of automated script codes to program and operate data. The distributed ledger connected by blockchain technology can allow two parties to effectively record transactions, and can Permanently check this transaction. Currently, the largest application of blockchain technology is digital currency, and it is also one of the top ten typical judicial technology applications on the Internet.

II What are the characteristics of blockchain technology

The four major characteristics of blockchain technology include: decentralization; trustlessness; scalability; anonymity. Decentralization: Due to the use of distributed computing and storage, there is no centralized hardware or management organization in the blockchain system. Therefore, the rights and obligations of any node are equal, and the data blocks in the system are maintained by the entire system. nodes to jointly maintain. Openness: The system is open. In addition to the private information of the transaction parties being encrypted, the blockchain data is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent. Autonomy: The blockchain adopts consensus-based specifications and protocols (such as a set of open and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trustless environment, so that trust in "people" is exchanged. It has become a trust in the machine, and no human intervention will work. Information cannot be tampered with: Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node will be invalid, so the area The data stability and reliability of blockchain are extremely high. Anonymity: Since the exchanges between nodes follow a fixed algorithm, the data interaction does not require trust (the program rules in the blockchain will judge whether the activity is valid by itself), so the counterparty does not need to reveal its identity to the other party. Generating trust is very helpful for the accumulation of credit. Reliability: The data on the blockchain saves multiple copies, and the failure of any node will not affect the reliability of the data. The consensus mechanism makes modifying large numbers of blocks extremely costly and almost impossible. Destroying data is not in the self-interest of important participants. This practical design enhances the reliability of data on the blockchain and global circulation: blockchain assets are first based on the Internet. As long as there is the Internet, blockchain assets can be circulated. The Internet here can be the World Wide Web or various local area networks, so blockchain assets are circulated globally. As long as there is Internet,You can transfer blockchain assets. Compared with the centralized method, the transfer fee for global circulation of blockchain assets is very low. For example, the early transfer fee for Bitcoin was 0.0001 BTC. Compared with traditional transfers, the transfer fee is very low. Blockchain assets arrive very quickly. It usually takes a few minutes to an hour to arrive.

ⅢWhich of the following options is not a characteristic of the blockchain?

Decentralized, Trustless, Collectivelymaintained ), reliable database (ReliableDatabase).

IV Characteristics of Blockchain Technology

The five basic characteristics of Blockchain technology are as follows:
1. Characteristics of Blockchain Technology 1: Distributed database
Every party on the blockchain has access to the entire database and its complete history. No single party controls the data or information. Each party can directly verify the records of its trading partners without the need for a middleman.
2. Blockchain technology feature 2: Peer-to-peer transmission
Communication occurs directly between peers, rather than through a central node. Each node stores and forwards information to all other nodes.
3. Blockchain technology feature three: Transparent anonymity
Any user with access to the system can see each transaction and its associated value. Each node or user on the blockchain has a unique address consisting of more than 30 letters and numbers, which is used to identify itself. Users can choose to remain anonymous or provide proof of their identity to others. The addition of the blockchain occurs at one of these addresses.
4. Blockchain technology feature four: Irreversibility of records
Once a transaction is entered in the database and an account is updated, the records cannot be changed because they are linked to every transaction record before them (hence the name "chain"). Various algorithms are employed to ensure that records in the database are permanent, chronologically ordered, and accessible to all other nodes on the network.
5. Features of Blockchain Technology Five: Computational Logic
The digital nature of the ledger means that blockchain transactions can be associated with computational logic and are essentially programmable. Therefore, users can set algorithms and rules that automatically trigger transactions between nodes.
Extended information:
Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes, and these nodes are usually in the hands of different subjects, so tampering with the information in the blockchainBreathing is an extremely difficult thing. Compared with traditional networks, blockchain has two core characteristics: data is difficult to tamper with and decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.

IV The technical characteristics of blockchain include: (). a Decentralization b Traceability c Openness and transparency d Non-tampering

The technical characteristics of blockchain include decentralization, non-tampering, consensus trust mechanism, openness, anonymity, cross-platform, etc.

6. Cross-platform

Similar to the TCP/IP protocol of the Internet, blockchain can also be regarded as a basic communication protocol. The cooperation of other mechanisms together constitutes the value Internet based on blockchain. Nodes on the blockchain network operate independently based on common algorithms and data structures. They mainly consume computing resources and have nothing to do with the platform. Computing nodes can be deployed on any platform.

It can be said that the characteristics and development of blockchain come from the soil where it was born - the development of Internet technology and the rise of cloud computing and big data.

VI What are the characteristics of blockchain

There are five main technical characteristics of blockchain, namely : Decentralized, information cannot be tampered with, open and transparent, collectively maintainable, and reliable database. It can be used in many aspects, for example, let’s take a rental agency. In the past, the agency had information about the property and the tenants. Moreover, some unscrupulous agents would change the information at will, just to make money in the middle. More agency fees. And if a blockchain is built and applied in the rental field, then the property information will be filled in by the landlord, and the tenant's information will be filled in by the tenant. Note that once the information is filled in, it cannot be changed twice. So this is equivalent to removing the center of intermediary. Of course, we are just talking briefly. In fact, deploying such a blockchain is also very complicated.
