Ⅰ What are the main characteristics of blockchain technology?

The following points are the characteristics that blockchain should have summarized by Jinwowo Group:

1-Decentralization: Since the blockchain relies on various nodes to jointly maintain the system and ensure the authenticity of information transmission, it is based on distributed storage of data without a center for centralized management. Therefore, a certain node Attacks and tampering will not affect the healthy operation of the entire network;

2-Trustlessness: establishing a connection between any two nodes does not require trusting each other's identities, and data exchange between the two parties does not require each other. The basis of trust. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud;

3-Scalable: Blockchain is an underlying open source technology. Various extensions, decentralization, and trustless applications can be realized;

4-Anonymization: Both parties to the data exchange can be anonymous, and the nodes in the network do not need to know each other's identities and personal information. Data exchange can be carried out

5-Safe and reliable: Since the activities between any nodes are supervised by the entire network, and the database uses distributed storage, for hackers, it is impossible to disguise and carry out Fraudulent activities, and secondly, the network cannot be controlled by simply conquering a certain node.

Ⅱ What is blockchain technology? What exactly is blockchain?

1. The so-called blockchain technology, referred to as BT (Blockchain technology), is also called Distributed ledger technology is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.

Explain in layman’s terms: If we assume that the database is a ledger, reading and writing the database can be regarded as an accounting behavior. The principle of blockchain technology is to find out the accounting information within a period of time. The fastest and best person will keep accounts, and then send this page of information to everyone else in the entire system.

2. Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of cryptographic methods. Each data block generated by the association contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

(2) Is distribution the main feature of blockchain technology? Further reading:

The blockchain system consists of data layer, network It consists of layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related data encryption and timestamps, etc.Basic data and basic algorithms; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates various consensus algorithms of network nodes.

The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the The basis of the chain's programmable features; the application layer encapsulates various application scenarios and cases of the blockchain.

Ⅲ What are the major characteristics of blockchain technology services

In general, the characteristic of blockchain is the use of block chain data structures to verify and store data. A new distributed infrastructure and computing that uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script codes to program and operate data. Method..., the cost of self-development is high, you can find relevant service providers such as: Renren Chain

IV What are the main characteristics of blockchain technology

It is understood that compared to Traditional centralized solutions, blockchain technology mainly have the following three characteristics:

The core idea of ​​blockchain is decentralization

In the blockchain system, The rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power, thus ensuring that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.

The biggest disruption of blockchain is the establishment of credit

Theoretically, blockchain technology can make WeChat Pay and Alipay no longer valuable. "The Economist" gave a vivid metaphor to the blockchain: simply put, it is "a machine that creates trust." Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.

The collective maintenance of blockchain can reduce costs

Under the centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and the cost Cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.

In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings rely for survival.

IV What does distribution in the blockchain mean?

Distribution in the blockchain is a new way of recording information. It is encrypted and distributed, which is a very practical way of recording information. This is like the teacher leaving us a question, not just for ourselves, butThere is one question left for everyone.

VI 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 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 peopleTrust in third-party centralized institutions.
Blockchain technology solves the problem of complete trust between people.

VII What are the main technical characteristics of blockchain?

“Blockchain is a shared distributed database technology, and its advantages are mainly reflected in distributed decentralization. ization, trustless system and non-tampering and encryption security.”
1. The meaning of blockchain technology
Blockchain (BlockChain) technology is a decentralized consensus mechanism that uses Technology that maintains a complete, distributed, non-tamperable ledger database, which enables participants in the blockchain to implement a unified ledger system without establishing a trust relationship. Blocks are public ledgers and are maintained at multiple points; chains are stamped with timestamps and cannot be forged. Blockchain is essentially a technology that values ​​security and credibility over efficiency.
There is a database behind all current systems, which is a big ledger. Then who will keep this ledger becomes very important. Now it’s whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction 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, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger.
Thus, the data becomes very secure. A tamperer needs to modify more than half of the system node data at the same time to truly tamper with the data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system. Therefore, it can be considered that blockchain technology is a way for all people to participate in accounting, and it will bring about innovation in accounting methods.
