A. The four characteristics of blockchain

Characteristics of blockchain

One of the four characteristics of blockchain: Cannot be tampered with.

The easiest-to-understand feature of blockchain is that it cannot be tampered with.

Immutability is a unique ledger based on "block + chain": blocks with transactions are continuously added to the end of the chain in chronological order. To modify data in a block, all blocks after that block must be regenerated.

An important role of the consensus mechanism is that the cost of modifying a large number of blocks is extremely high and almost impossible. Take blockchain networks with proof-of-work (such as Bitcoin and Ethereum) as an example. Only 51% of the computing power is needed to regenerate all block tampering data. However, destroying data is not in the self-interest of players with significant computing power. This practical design improves the reliability of blockchain data.

Normally, the transaction data in the blockchain account book can be regarded as not being "modified", and only approved new transactions can be "modified". The modification process will leave traces, which is why the blockchain cannot be tampered with. Tampering means changing or misinterpreting by forgery.

B. What are the characteristics of blockchain?

High security. The blockchain is not controlled by any person or entity, and the data is completely replicated on multiple computers. Without a single entry point for attackers, data security is more secure. The data cannot be tampered with. Once it enters the blockchain, no information can be changed, and even the administrator cannot modify this information. No third parties and accessible. Blockchain is decentralized and helps peer-to-peer transactions, whether it is trading or exchanging funds, without waiting for approval from three parties. Moreover, all nodes in the network can easily access the information.
The biggest feature of blockchain is decentralization. Decentralization means that all operations are deployed on distributed ledgers and no longer deployed on the servers of centralized institutions.
Blockchain is a new application that combines distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies.
Basic features include: decentralization, openness, autonomy, information cannot be tampered with, and anonymity.
1. Decentralization
Since the blockchain uses distributed storage and has no central hardware and institutions, the rights and responsibilities of any node are equal, and the data in the system is jointly maintained by all nodes.
On the traditional Internet, such as Facebook and Tencent, the private data of billions of people is managed by one company and maintained by a central server.
Therefore, traditional Internet databases lack security and privacy, and hackers and leaks often occur.
2. Openness
The blockchain system is open, and the public chain code is open source. In addition to encrypting the private information of the transaction parties, the data is open to the public. Anyone can query the data, and the system data is highly transparent.
3. Autonomy
Autonomy is based on norms and protocols. Blockchain technology adopts protocol-basedConsistent specifications and protocols (such as open and transparent algorithms).
Enable all nodes in the system to exchange data freely and securely in a trustless environment.
Change the traditional Internet's trust in people to trust in physical machines such as mathematics, cryptography, and computers.
No one can interfere with the trust of the blockchain protocol.
4. Data cannot be tampered
Once the information is verified by all nodes and added to the blockchain, it will be permanently recorded.
Unless more than 51% of the nodes in the system are controlled at the same time, private tampering with the database on a single node is invalid and cannot be recorded on the chain.
Therefore, the stability and security of blockchain data are very high.
On the contrary, on the traditional Internet, the central server backend of a centralized organization can tamper with anyone's data at any time, block your website, web page, account, etc., and there is no security at all.
5. Anonymity
Exchanges between blockchain nodes are strictly performed according to fixed algorithms.
The information exchange does not require trust. In other words, all parties to the transaction have unconditional trust.
Traditional trust is trust between people, or people’s trust in third-party centralized institutions.
Blockchain technology solves the problem of complete trust between people.

C. 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.

D. What are the characteristics of blockchain?

Characteristics of blockchain: 1. Security: not subject to attack by any person or entity; 2. No information can be tampered with; 3. Traceable , all nodes in the network are accessible; 4. Decentralized, no third party. Regarding blockchain news, you can learn about it at Crypto Finance.

E. 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. Cooperate with other mechanisms to jointly constructIt has become a 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.

F. The technical characteristics of blockchain include

With the development of digital cryptocurrencies represented by Bitcoin, With its strong rise, the emerging blockchain technology has gradually become a hot research topic in academia and industry. The characteristics of blockchain technology such as decentralized credit, non-tamperability and programmability make it have broad application prospects in digital cryptocurrency, financial and social systems. Blockchain-related domain names such as .top have also been registered under the blockchain wave, and related applications can be seen on many trading platforms.
Blockchain technology has three obvious characteristics: publicity, security and uniqueness.
Publicity mainly means that the information stored in the blockchain is completely open to all participants. This is mainly determined by the blockchain point-to-point network storage method. In the blockchain network, each node can store a copy of the blockchain, and the uniqueness of the blockchain can ensure that this copy is consistent between different nodes. exactly the same.
Security mainly means that the information stored in the blockchain block is saved after being processed by digital encryption technology. Only the holder of the private key can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of the information, but cannot see the real information.
The uniqueness feature is mainly due to the fact that once the information on the blockchain cannot be tampered with, it is unique. Of course, the uniqueness mentioned here also includes uniqueness in space, that is, all nodes have only one version of the same information, and uniqueness in time, that is, historical data cannot be changed. This uniqueness also refers to the characteristic that the blockchain maintains only one main chain during its operation. Once other chains appear, there will be a fork. The emergence of forks will cause the blockchain to appear in two different spatial dimensions. Of course, solving this problem requires setting reasonable consensus rules to avoid it. When the blockchain concept was hot, many related top domain names were registered and used as blockchain platforms.

G. 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 and anyone can check it through the public interface.Consult blockchain data and develop related applications, so 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 the Internet, blockchain assets can be transferred. Compared with centralized methods, the transfer fees for global circulation of blockchain assets are very low. For example, the early transfer fee for Bitcoin was 0.0001 BTC. Compared with traditional transfers, Generally speaking, blockchain assets arrive very quickly. It usually takes a few minutes to an hour to arrive.

H. What are the characteristics of blockchain?

What are the characteristics of blockchain? Let’s get to know He Meng:
1. Decentralization
Blockchain technology does not rely on additional third-party management agencies or hardware facilities. There is no central control, except for self-contained zones. In the blockchain itself, through distributed accounting and storage, each node realizes information self-verification, transmission and management. This is also the most prominent and essential feature of blockchain.
2. Openness
The foundation of blockchain technology is open source. In addition to the private information of the parties to the transaction being encrypted, the data of the blockchain will be open to everyone, and anyone can use the public interface When querying blockchain data and developing related applications, it can be said that the entire system information is highly transparent.
3. Independence
Based on consensus specifications and protocols, the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without any human intervention.
4. Security
As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will, which makes the blockchain itselfIt is much safer and avoids subjective and artificial data changes.
5. Anonymity
Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be done directly and anonymously.
The above is the editor's Zen Zen Zaoqiao experience, I hope it can help everyone.

I. What are the application characteristics of blockchain technology

Blockchain is a shared distributed database technology. Although the one-sentence introduction to blockchain is worded differently in different reports, the following four technical features are consistent.
1. Decentralized: The left side describes the centralized characteristics of today’s financial system, and the right side describes the emerging decentralized financial system, which has no intermediaries and the rights and obligations of all nodes. All are equal, if any node stops working, it will not affect the operation of the entire system;
2. Trustless: All nodes in the system can conduct transactions without trust, because the operation of the database and the entire system is public Transparent, within the rules and time range of the system, nodes cannot deceive each other;
3. Collectively Maintain: The system is jointly maintained by all nodes with maintenance functions, and everyone in the system Participate in maintenance work together;
4. Reliable Database: Each node in the system has the latest complete database copy. Modifying the database of a single node is invalid because the system will automatically compare and consider the most frequent occurrences. The same data records are true.
