区块链最根本的特性是什么,区块链最根本的特性在于
区块链最根本的特性是去中心化、不可篡改和透明度。接下来，我们将分别介绍这三个关键词。
去中心化：去中心化是区块链技术的核心特性之一。它是指没有中央机构或者第三方参与，而是通过区块链网络中的大量节点实现信息的存储和传输，从而达到信息安全性和可靠性的目的。去中心化的优点是，它使网络中的信息更加安全，因为它不受任何一个特定的实体的控制，也不会受到任何第三方的影响，而且可以实现信息的快速传输。
不可篡改：不可篡改是指在区块链网络中，一旦信息被记录，就不可更改。这是因为，在区块链网络中，所有的信息都是通过对等网络中的大量节点进行分布式处理实现的，这些节点的数据会被不断的备份，从而保证数据的完整性，而且这些数据都是通过加密技术进行加密，从而使得数据不可篡改。
透明度：透明度是指在区块链网络中，所有的信息都是公开可见的，任何人都可以查看，而且信息一旦被记录，就不可更改。这样，可以保证网络中的信息是真实可靠的，也可以有效的防止网络中的欺诈行为。此外，由于所有的信息都是公开可见的，所以可以有效的防止企业的账户操纵行为，从而使得经济活动更加公平和透明。
以上就是区块链最根本的特性：去中心化、不可篡改和透明度。它们的结合，使得区块链技术已经成为了当今社会信息安全的重要基石，也是未来信息安全的重要发展方向。

A. Characteristics of blockchain
1. Decentralization
The so-called decentralization refers to the use of distributed computing in blockchain and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by nodes with maintenance functions in the entire system.
2. Openness
The so-called openness means that the blockchain system is open. In addition to encrypting the private information of the transaction parties, the blockchain data is open to everyone. Public, anyone can query blockchain data through the public interface and develop related applications. The information of the entire system is highly transparent.
3. Autonomy
The autonomy feature of blockchain is based on specifications and protocols. The blockchain adopts consensus-based specifications and protocols (such as open and transparent algorithms), so that all nodes in the system can freely and securely exchange data in a trustless environment, changing trust in "people" to machines. trust, no human intervention can work.
4. Information cannot be tampered
Because of this, the stability and reliability of blockchain data are very high. Blockchain technology has fundamentally changed the centralized credit creation method, using mathematical principles rather than centralized credit institutions. To establish credit at low cost, birth certificates, real estate certificates, marriage certificates, etc. can be notarized on the blockchain, with a global central node, becoming something that is trusted by the world.
5. Anonymity
The so-called anonymity means that the exchange between nodes follows a fixed algorithm. The data interaction does not require trust, and the counterparty does not need to disclose its identity. The other party has trust in you, which is conducive to the accumulation of credit.
Lianxin is a blockchain application with tens of millions of member users. It has its own Quark blockchain as a public chain, qkibill open source wallet, and independent block browser. It is a completely independent A blockchain platform where users control their own data, QuarkChain’s innovative blockchain plus life service platform is committed to creating better blockchain services. The ChainChain blockchain has the above characteristics and is a real blockchain chain project.
B. What are the basic characteristics of blockchain
Answer: The basic characteristics of blockchain
1. Decentralization.
Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, through distributed accounting and storage, each node realizes self-verification and transmission of information. and management.
2. Openness.
The foundation of blockchain technology is open source. 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 information through the public interface. Develop related applications, so the entire system information is highly transparent.
3. Independence.
Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties, and all nodes can automatically and securely operate within the system. Verification and exchange of data do not require any human intervention.
4. Security.
As long as you cannot control 51% of all data nodes, you cannot arbitrarily manipulate and modify network data. This makes the blockchain itself relatively safe 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 anonymously.
C. Characteristics of blockchain
Characteristics of blockchain:
1. Anonymous/Anonymous
Due to the Exchanges follow a fixed and predictable algorithm, so the blockchain network is trustless and can exchange data based on addresses rather than personal identities.
2. Autonomous
The blockchain adopts a consensus-based mechanism to enable all nodes in the entire system to freely and securely exchange data, record data, and update data in a trustless environment. No human intervention works.
3. Openness/Openness
The blockchain system is open, and any node can have the general ledger of the entire network. In addition to the private information of the parties directly related to the data being encrypted through asymmetric encryption technology , the data of the blockchain is open to all nodes, so the entire system information is highly transparent.
4. Programmable
The digital nature of distributed ledgers means that blockchain transactions can be associated with computational logic and are programmable in nature. Therefore, users can set algorithms and rules that automatically trigger transactions between nodes.
5. Traceability/Traceability
The blockchain stores all historical data after the creation block through the block data structure. Any piece of data on the blockchain can be traced through the chain structure. origin.
6. Untamperable/Tamper Proof
After the blockchain information passes consensus and is added to the blockchain, it is jointly recorded by all nodes and is interconnected through cryptography to ensure that the difficulty of tampering is related to The cost is very high.
7. Collectively Maintain/Collectively Maintain
The blockchain system is composed of all nodes with maintenance functions.Jointly maintained by all nodes, all nodes can query blockchain data and develop related applications through public interfaces.
8. Permissionless/Permissionless
Permissionless means that all nodes can request that any transaction be added to the blockchain, but the transaction can only be carried out if all users consider it legal.
D. What are the characteristics of blockchain?
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.
E. 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, there is no central hardware and institution, and the rights and responsibilities of any node are equal., 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 uses consensus-based 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.

F. Continuing Education: The most fundamental feature of blockchain network
The most fundamental feature of blockchain network is blockchain. Its core idea is decentralization. Blockchain The biggest disruption lies in the establishment of credit, and the collective maintenance of blockchain can reduce costs. Public Blockchain Network A public blockchain is a blockchain that anyone can join and participate in, such as Bitcoin. Disadvantages may include the large amount of computing power required, little or no privacy for transactions, and weak security.
1. Blockchain is a serial transaction record that uses cryptography to connect and protect content. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. As an important concept of Bitcoin, blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data generated using cryptographic methods.
G. Characteristics of blockchain technology
The five basic characteristics of blockchain technology are as follows:
1. Blockchain technologyTechnical Feature 1: Distributed Database
Every party on the blockchain can access 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. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. 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.
