❶ What exactly is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Simply put, blockchain is a decentralized distributed ledger database.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. After reading this, you may still be confused. In fact, in vernacular terms, blockchain is a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can trade directly without any intermediary. Everyone has a backup, even if your copy is lost, it will not be affected.

So what is distribution and decentralization? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer to complete the legal process. What if we use blockchain technology? As long as two people agree to get married and post a message in their circle of friends, the marriage process is completed and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses. They may be scattered around the world, but their mobile phones will help you record the information and tell others who want to know the situation.

If you want to conceal your marriage information, you used to have to modify the records on the Civil Affairs Bureau's computer, but now you have to modify the records on the mobile phones of all insiders at the same time. The more people who know about it, the less likely it is to modify it. Therefore it is an impossible task. This is distribution and decentralization.

On the network, every once in a while, a block will be generated. This block is equivalent to a network record book, which is used to record relevant information that has occurred over a period of time. Waiting for this record book When the record is full, a new record book will be generated. Once the information is recorded, all participants will be notified and everyone's record book will be updated simultaneously.

These record books are eventually connected in series with each other. This is blockchain technology. Because of the use of cryptography technology, if someone wants to unilaterally tamper with the message, it will be verified through the blockchain algorithm protection mechanism. If the time point does not match and the related information does not match, other people will not update their own records. Then this information is invalid.

Therefore, compared with traditional information storage technology, blockchain technology is more secure, transparent, and information is irreversible.

Blockchain is not equal to Bitcoin, it is just an underlying technology invented to realize the digital currency of Bitcoin. Blockchain can be applied in a wider range. In addition to digital currency, it can also be applied in financial aspects such as P2P lending, global payment, micro-finance, electronic payment, remittance, etc. It can also be used in people's livelihood aspects such as intellectual property, elections, and notarization. The prospects for future development are huge.

❷ What is blockchain technology? What is blockchain in popular terms?Explanation

Blockchain has been at the forefront since the end of October.

What is blockchain technology

Although blockchain has been around for more than ten years, many people still don’t know much about this technology.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. From an application perspective, blockchain is a distributed ledger.

So, why is the blockchain called the blockchain?

Because the blockchain itself is a series of linked blocks, these blocks are filled with transaction records. The blocks are much like the records of a database. Every time data is written, it is Create a block. With the expansion of information exchange, one block continues with another, and the result is called a blockchain.

What are the characteristics of blockchain technology?

Simply put, blockchain has the characteristics of decentralization, openness, non-tampering, and anonymity.

1. Decentralization:

In the blockchain system, there is no center.

In the blockchain model, it is distributed accounting and storage. Each node self-verifies, transmits, and manages information. Each node is the center, which is decentralization.

2. Openness:

The blockchain system has the characteristics of openness, the data is open, and anyone can query the blockchain data and data through the public interface. Develop related applications.

3. Information cannot be tampered with:

In the blockchain system, once the data is written, the tampering cannot be undone unless 51% of all data nodes are controlled. Forge a record that does not exist. Therefore, blockchain technology has a certain degree of security.

4. Privacy and anonymity:

The cryptography technology in the blockchain can effectively achieve identity concealment.

The identity information of each node does not need to be disclosed or verified, and information transfer can be done anonymously. It can only be accessed with the authorization of the data owner, thus ensuring data security and personal privacy.

Xiao Li lent 10,000 yuan to Xiao Wang. Xiao Li found two people in common and Xiao Bai to prove it. This accounting model is a centralized accounting model, and Xiaobai is the center.

However, a year later, when Xiao Li wanted to get the money back, Xiao Wang Shikou denied that he had lent him the money. It turned out that Xiao Wang introduced Xiao Bai's girlfriend to his company. a job.

This is centralizationDisadvantages of accounts.

Xiao Li learned a lesson and gained wisdom. In the future, when someone asked him to borrow money, he said on WeChat in the village that I would lend so-and-so how much money. In this way, everyone in the village knew that Xiao Li How much money did Li lend to whom?

In this way, when Xiao Li asks for debt again in the future, the other party will not deny the issue, because a consensus mechanism has been established in the minds of the people in the village: How much did you borrow from Xiao Li? .

This is the advantage of decentralized accounting.

Because after all, there are many people to testify about this transaction. If it seems to be a fraud, it will be unless more than half of the people in the village are bought. However, the price is very high.

In fact, these characteristics of the blockchain are all to solve the problem of "trust". The rich application scenarios of the blockchain are also based on the blockchain's ability to solve the problem of information asymmetry. At the same time, Blockchain also helps achieve collaborative trust and consistent action among multiple entities.

What are the applications of blockchain?

In addition to digital currency, there are many application scenarios of blockchain.

1. Medical field

Blockchain helps realize smart medical care, such as going to the hospital to see a doctor. Through the blockchain model, the patient’s medical status, cases, treatment status, etc. are all Clearly visible, saving a lot of medical resources.

2. Copyright field

Blockchain can prove the authenticity and uniqueness of the copyright of works, from the birth to the transfer of audio, video, pictures, text and other works. Can be tracked and recorded, and form tamper-proof information.

3. Logistics field

After applying blockchain in the logistics field, goods can be traced from production to consumption.

4. Food safety

Is blockchain used for food safety? Through blockchain traceability, one can easily trace the past and present life of their food.

5. Securities trading

For example, traditional securities trading requires the coordination of multiple institutions to complete, while the blockchain system can independently complete one-stop transactions. This service can make securities trading simpler and faster.

However, many people have big misunderstandings about blockchain. The biggest misunderstanding is: blockchain = Bitcoin

In fact, blockchain and Bitcoin is not the same thing. Blockchain is the underlying technology of Bitcoin, and Bitcoin is the first application of blockchain.

❸ Popular explanation of what blockchain is

Blockchain is a distributed and decentralized computer technology. Blockchain is not equal to Bitcoin,It is just an underlying technology invented to realize the digital currency of Bitcoin. Blockchain can be applied in a wider range. In addition to digital currency, it can also be applied in financial aspects such as P2P lending, global payment, micro-finance, electronic payment, remittance, etc. It can also be used in people's livelihood aspects such as intellectual property, elections, and notarization. The prospects for future development are huge.

So, what is distributed and decentralized? Take marriage registration as an example. In the past, when two people got married, they had to go to the Civil Affairs Bureau to go through the formalities, and then enter the information into the computer. Only then has the legal process been completed. What if blockchain technology is used? As long as two people agree to get married and then post a message in their circle of friends, the marriage process is completed, and there is no need to go to the Civil Affairs Bureau. Your friends are common witnesses. They may be scattered around the world, but their mobile phones will help you record the information and tell others who want to know the situation.

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, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is 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 transaction parties being encrypted, the data of the blockchain 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.

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. All nodes can automatically and securely verify and exchange data within the system without the need for 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. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.

❹ What does blockchain mean and what are the characteristics of blockchain?

As for the technology of blockchain, I believe many friends have already paid attention to it. Blockchain It can be said to be a hot topic right now, with news media reporting heavily on it claiming it will create the future. So what does blockchain mean? What are the characteristics of blockchain? Today we will introduce the blockchain to you in detail, and hope that you will have a deep understanding after reading it.
What does blockchain mean?
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism isA mathematical algorithm for establishing trust and obtaining rights and interests between different nodes in the blockchain system.
Blockchain is also an important concept of Bitcoin. The "2014-2016 Global Bitcoin Development Research Report" released by the Internet Finance Laboratory of Tsinghua University PBC School of Finance and Sina Technology mentioned that blockchain is Bitcoin's underlying technology and infrastructure.
Blockchain is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Ledger.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses A new distributed infrastructure and computing paradigm that uses smart contracts composed of automated script code to program and manipulate data.
What are the characteristics of blockchain?
Through the summary and analysis of the blockchain, it is concluded that the characteristics of the blockchain have the following four main points: Open Yingpai
1. The first is the disintermediation of trust, which has been repeatedly emphasized and praised. What Weihe said yesterday is not decentralization but disintermediation, which coincides with each other.
2. The second feature is its stability, reliability, and sustainability. Because it is a distributed network architecture, no central node can be hit or attacked, so in the overall technical layout It has stronger stability, reliability and sustainability.
3. Third, its strong security and consensus mechanism do not require the entry of a third party, but are achieved through a technology, a previously scheduled technology to complete the entire transaction.
4. The fourth is the openness, transparency and non-tamperability of transactions. Many practitioners in the industry have shared these characteristics with you, so these are the four characteristics of the blockchain.
Because of these characteristics, blockchain can receive huge attention from many financial institutions and many industries in the future or now.
The above is what the editor brings to you. What does blockchain mean? What are the characteristics of blockchain? all content.

❺ What is the concept of blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. It is a concept related to Bitcoin and is essentially a decentralized database. In addition, as the underlying technology of most digital currencies such as Bitcoin, it is a series of data blocks created using cryptography-related knowledge. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the relevant information and generate the next block. it isA mathematical architecture for data storage built in a way that is almost impossible to forge or modify and can be used to store all kinds of valuable data.

A public blockchain refers to a blockchain that can be traded by any individual or group in the world. Transactions can be done through blocks The chain is effectively confirmed and everyone can participate in this consensus process. The public chain is the first blockchain to be produced and the most widely used blockchain. The virtual digital currencies of all major Bitcoin series are based on public chains, and there is only one blockchain in the world corresponding to this currency.

❻ What does blockchain mean?

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

1. Blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Distributed ledger.

2. Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of Bitcoin, it is a series of related cryptographic methods. data block.

(6) Is the blockchain an algorithm? Extended reading:

1. The Bitcoin peer-to-peer network stores all transaction history in In "blockchain". The blockchain continues to lengthen, and once new blocks are added to the blockchain, they cannot be removed.

2. The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof of work and algorithms, such as the use of proof of equity and SCrypt algorithms.

3. The blockchain is actually a group of dispersed user nodes and a distributed database composed of all participants. It is a record of all Bitcoin transaction history.

4. Blockchain technology will be applied to credit reporting, transaction security and information security in the financial industry. Blockchain can form point-to-point digital value transfer in finance, thus improving the security of transmission and transactions.

❼ What is blockchain and how to simply understand blockchain technology

What is blockchain

Blockchain is through point-to-point transmission, A new technology for encrypting algorithms. There are countless points in the blockchain. Each point represents a user. If a transaction occurs between points, the transaction record will be directly uploaded to the block. The data in the block will be uploaded according to time. Linked sequentially is a blockchain.

1. Blockchain is also called a distributed ledger. The ledger records the transaction records of all nodes. Each node needs to maintain the development of the blockchain, supervise whether the transactions are legal, and can also work together to Transaction testimony.

2. Encryption technology. Transaction information in the blockchain is public, but personal information isIf the encryption algorithm is used, there is no need to worry about the leakage of personal information. Only with personal authorization can the other party query personal information, ensuring the security of personal information.

3. Consensus mechanism. Every node in the blockchain trusts each other. Every user can trade with confidence because the data cannot be tampered with and every transaction must be legal and will not There is a possibility of fraud.

4. In scenarios where smart contracts and blockchain technology are applied, intelligent matching can be used. For example, insurance claims can be automatically settled.

How to simply understand blockchain technology

Blockchain technology can be understood in this way. Xiaohei and Xiaobai are both nodes in the blockchain. Borrowing 1,000 yuan is a transaction, and the data will be stored in the block. At this time, Xiaobai broadcasts to everyone that Xiaohei borrowed 1,000 yuan from him, and Xiaohei also broadcasts that he borrowed money from Xiaobai. He borrowed 1,000 yuan from Xiaobai. Everyone heard the news. On the repayment day, Xiaohei said that he had not borrowed 1,000 yuan from Xiaobai. At this time, everyone came out to testify to Xiaobai that Xiaohei had indeed borrowed money. 1,000 yuan.

In the above example, Xiao Hei and Xiao Bai are equivalent to the two nodes of the blockchain. Borrowing money is a transaction. As long as the transaction is made, transaction data will be generated and uploaded directly to the block. The data in the block is public. Not only can you see it, but everyone in the blockchain can see it. This ensures that Xiaohei will not breach the contract and say that he did not borrow the money. Everyone in the block will supervise Xiaohei. To repay the money, it ensures the legality of the transaction and mutual trust between each node.
