去信任化是区块链技术去中心化的一个核心概念，它意味着不需要依赖中心化的机构来保证数据的可靠性，而是通过分布式的网络来实现。去信任化的本质是，网络中的每个节点都可以获得数据，并且可以对数据进行验证，从而确保数据的可靠性。

去中心化账本是区块链技术去中心化的另一个关键概念，它是一种分布式的账本系统，它可以记录和管理网络中的所有交易信息，而且这些交易信息是可信赖的，因为它们是由网络中的所有节点共同管理的。去中心化账本的本质是，它可以让网络中的每个节点都可以查看和管理交易信息，而不需要依赖中心化的机构来确保数据的可靠性。

共识机制是区块链技术去中心化的又一个关键概念，它是一种分布式的投票机制，它可以让网络中的每个节点都可以参与到数据的更新过程中，并且可以让网络中的每个节点都可以对数据的更新进行验证，从而确保数据的可靠性。共识机制的本质是，它可以让网络中的每个节点都可以参与到数据更新的过程中，并且可以让网络中的每个节点都可以对数据的更新进行验证，从而确保数据的可靠性。

总之，区块链技术的去中心化本质是去除中心化的组织结构，它把数据分布在网络的节点上，每个节点都可以查看数据，并且可以更新数据，数据的更新可以得到网络中其他节点的批准，从而使得数据更新变得可靠。其中，去信任化、去中心化账本和共识机制是区块链技术去中心化的三个关键概念，它们可以让网络中的每个节点都可以参与到数据的更新过程中，并且可以让网络中的每个节点都可以对数据的更新进行验证，从而确保数据的可靠性。

⑴ What does "decentralization" of blockchain mean?

Comparative analysis of centralized server finance and decentralized blockchain finance

1. Login interface:
Centralization: There is an independent domain name, server, website, and app member management entrance login.
Decentralized: no server, no domain name and no app. The dapp browsers of third-party Ethereum (ETH) wallets are all entrances, such as Binance Wallet, AM Wallet, Math Wallet, etc. Dapp can only be read in the block explorer.

2. Essential differences:
Centralization:
1. The model and data are stored on the server and can be modified at will, and the outflow of funds can be controlled.
2. Financial data cannot be disclosed to investors. Bonuses are settled uniformly by financial personnel.
3. There is the possibility and feasibility of making money and running away.

Decentralization:
1. The entire business model relies on the automatic execution of Ethereum (ETH) smart contracts and is separated from human management.
2. Financial openness and transparency, bonus block settlement.
3. Eliminate the possibility of making money and running away.

3. Security of personal information and funds:
Centralization:
1. Requirements for ordering: name, phone number, ID card, bank card and other information. Personal information may be leaked. Danger.
2. The funds are stored in the bank card or centralized wallet of the project party. When the entry funds > the exit funds, it will continue to run. When the entry funds are
Decentralized:
1. No need for any The profile is the Ethereum (ETH) wallet address used as identification.
2. Funds are stored in the Ethereum (ETH) contract wallet address. No individual or organization can transfer Ethereum. No matter how the funds change, the possibility of trapping money and running away is eliminated.

4. Bubbles and Risk Analysis

Centralization:
1. Development and operation costs 10%-20%
2. Company profit 30 %-80%
3. The market allocation ratio is 10%-50% as static and dynamic bonuses.

Decentralization:
1. No development and operation costs.
2. Technical profit 3%
3. Market allocation 97% as static and dynamic bonuses.

To sum up: centralized projects will inevitably perish, while decentralized projects will win the hearts of the people!

⑵ The decentralized nature of blockchain digital currency

For blockchain practitioners, if there is any word that has been heard in the past two years, then "Decentralization" can definitely occupy a place in this. From the confused look on my face when I first came into contact, to the mantra that is on my lips all the time now, "Go to China"It only took more than a year for the word "centralization" to come to the fore in 2018 and spread across the world today. So far, the "decentralization" of various behaviors has become a key issue in the blockchain industry. A political correctness within.

Practitioners hate the cloud platforms of Internet giants because it makes data storage not decentralized enough; they hate the emergence of monopoly giants in the industry because it makes the industry structure not decentralized enough. ; I also hate having a leader with one voice, because this makes the decision-making mechanism not decentralized enough. I even hate working in one office, because it makes people’s activities not decentralized enough... which makes the words and deeds of many practitioners now slightly different. If you are "centralized", you will be cautious and cautious, for fear of being criticized by the outside world.

So, what exactly is "decentralization"? What is its essence?

The sinking of power: the true essence of decentralization

In fact, regarding the matter of decentralization, the author has already stated in ["Prospects of Blockchain 3.0: Is decentralized community useless or the future?” It was once pointed out in the article: Decentralization is not a trend that people subjectively promote, let alone a false proposition promoted by blockchain practitioners, but economic and An objective inevitable result of the development of science and technology, in other words, the decentralization trend of society is the result of everyone voting with their feet under the current situation, and it is not based on people's subjective will.

If you don’t believe it, let’s look back at the technological products before the blockchain industry exploded - the abundance of civilian cars has enabled more and more people to participate in what in the past only passenger transport and taxi companies could engage in. In passenger transportation services, the decentralization of driving services has been achieved; with a smartphone in each hand, everyone has the opportunity to record the world around them with a lens, thus achieving the decentralization of photography and video rights; with the Internet extending in all directions, This allows every individual to have the opportunity to express his or her own voice, thereby decentralizing the right to speak; and the popularity of e-commerce platforms allows those who have the ability and intention to open a store to have the opportunity to run their own business. This further realizes the decentralization of the right to open a store...

From the above cases, we can easily see that long before it became famous with the help of the last bull market and Satoshi Nakamoto’s Bitcoin white paper, The phenomenon of "decentralization" is already everywhere. Why does this happen?

Regarding this point, the author has previously discussed it in ["Blockchain: The Last Internet Celebrity in the Digital World" ] mentioned briefly: For individuals, the biggest benefits that digital technology and the digital economy bring to them are two points: First, some of the costs that hindered their actions in the past are concentrated on centralized giants, such as the sharing economy. Time-sharing leasing can eliminate the need for many people to carry various necessary items; second, all kinds of rights and interests can beShen is dispersed into the hands of individuals, such as the passenger rights of car owners mentioned above, the photography rights of smartphone holders, the voice of Internet users, and the right of goods and service providers to open stores...

In other words, no matter what kind of decentralization it is, its essence actually refers to the sinking of various powers from top-level centralized institutions to grassroots individuals. As long as the development of economy and technology It is still benefiting every smaller group or individual, and this downward trend will not stop. The "decentralization" advocated by the blockchain is actually just one of the countless decentralized powers in this technological wave - that is, the right to mint money (or the right to record information). In other words, Blockchain digital currency, including Bitcoin, is not the first decentralized product, and it will definitely not be the last decentralized product.

The boundaries of freedom: any decentralization has limits**

However, we should also pay attention to one thing: although in theory, "decentralization" The ultimate goal is to sink power into everyone's hands, but in reality, since the proper use of any power is inseparable from the user's good professionalism and moral standards, from a longitudinal perspective, the power of these powers There is a bottom line for many sinking rates. From a horizontal perspective, the degree of decentralization is limited (that is, what many people often call "polycentering").

If certain powers are allowed to continue to sink vertically, that is, the industry continues to be decentralized from the front, it is likely to lead to certain uncontrollable situations, such as the well-known Passenger transportation rights (that is, online ride-hailing), this kind of power to provide passenger transportation services can only sink to the level of car owners with driver's licenses and good conduct. If this bottom line is exceeded and continues to sink, various online ride-hailing services last year The chances of violence will skyrocket.

By the way, as the saying goes, every industry is like a mountain. Since different industries have different requirements for the professionalism of power users, the maximum sinking degree of different powers is often different, and what they can tolerate The degree of decentralization also varies. For example, regarding the sinking of photography rights, since a single video itself generally does not have a great negative impact on society, even if it is not professional enough and it is shot randomly, it may be understandable. Therefore, as long as no darknet-style works are produced, let There is often no problem with this kind of power sinking into everyone's hands.

But if things like blockchain minting rights fall into the hands of those who are not objectively competent enough or subjectively irresponsible, the digital currency market will see a big problem. There are a lot of money-making and deceiving projects. Under such circumstances, the minting power can only be transferred to those individuals or teams that are professional, marketing and ethical at most (that is, the author previously mentioned in ["Practical, Positive and Kind: The Most SuitableThe three elements mentioned in the article "The Road to Blockchain for Ordinary People"), otherwise, the grand scene of "the city is full of air coins" in 2017 and 2018 will soon reappear in us in the world.

However, it is a pity that many people do not have an objective and correct understanding of "decentralization has limits". In reality, they love to go to extremes. When they first came into contact with blockchain and digital currency, they believed that the astonishing price increase of this new thing came largely from the distributed minting rights, so whenever there was any regulatory disturbance, they would shout out ideals and freedom with great resistance. slogan, as if all of them were anarchists; but after the collapse of air coins and altcoins, and their own interests were damaged, they threw down the decentralized flag they had previously waved, and cried everywhere why Master Qingtian didn't care. Take care of this lawless and barbaric land.

The swing between the two poles gives people a sense of confusion. The reason for this situation is ultimately because they do not realize: decentralization, that is, the sinking of various powers, It has limits, especially for the highly professional blockchain minting rights. The "everyone can mint money and print money" imagined by some people before can only be an ideal. If you are not aware of this objective fact, it is very likely that a funny situation will arise where "the front foot loves freedom and the back foot advocates authority."

Nonetheless, even if power cannot be decentralized without limit and decentralization cannot be too distributed, it does not mean that related initiatives are meaningless. The decentralization of minting power represented by Bitcoin and blockchain may be difficult to completely sink into the hands of every individual as Satoshi Nakamoto envisioned, but it has combined the word "decentralization" and related The concept of freedom is rooted in the hearts of countless investors and practitioners. Let them have a clearer understanding of the issue of "whose hands should hold various powers in the future?"

Although many people’s current accusations against centralized institutions are not entirely true, such as the accusation that one mining machine manufacturer is the dominant one; and some current “forced decentralization” behaviors are not entirely valid. Not particularly successful, just like Bitmain’s dual-CEO structure. But from a long-term perspective, these immature words and deeds are just a small wave at the beginning of the development of social decentralization. Just as once the floodgates are opened, the water flow cannot be stopped; when the concept of "decentralization" is rooted in people's hearts, the equal rights movement in various vertical fields is inevitable. The key is that power will sink from the original centralized institutions. The question is which level to go to.

From this point of view, decentralization has become an unstoppable torrent of social development, and the large amount of social resources we have seen in the past ten years have been redistributed to a large extent. It is also the result of this decentralization of power. Under such circumstances, people, including some blockchain practitioners, began to pursue the victory andThe target is another "Chinese-prefixed" target - that is, intermediaries. However, does "decentralization" equal "disintermediation"? Is the latter, like the former, an irreversible trend? The author will introduce the relevant content in detail in the next series of articles.

⑶ What is blockchain and what does it mean in popular terms? What is China’s attitude towards blockchain?

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin.

⑷ Blockchain has become a new pyramid scheme, what exactly is blockchain?

Some time ago, a photo of a Chinese aunt appearing at a blockchain conference was It became popular on the Internet and sparked heated discussions for a while. Netizens said: "Aunts have been targeted by blockchain." In fact, starting from a few years ago, when the concept of blockchain came out, there were some Criminals conduct pyramid schemes in the name of blockchain, becoming one of the latest variants of pyramid schemes. In fact, with the development of blockchain, various virtual currencies have emerged as the times require. Most of them are scams. Scammers carry out scams in the name of "virtual currency" and "blockchain". This is mainly to use Investors do not understand virtual currency and blockchain, but they want to catch up with the virtual currency investment boom. This scam seems complicated, but it is actually very simple. However, once you are fooled, it is difficult to recover your investment.

In short, blockchain technology is not actually a scam, but has been used by scammers to take advantage of information asymmetry to deceive investors.

⑸ Popular explanation of what blockchain is

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: decentralization A distributed accounting system
The core of blockchain technology is that all currently participating nodes jointly maintain transactions and databases. It makes transactions based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly Payment transactions are carried out without the involvement of a third party.
?
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All miner nodes compete to calculate the answer to the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.
1.1 What is a district?Blockchain
Blockchain (BlockChain) refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and chain to the next database block.
?
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. Behind all systems there is a database, which is a big ledger. Then who will keep this ledger becomes very important. At present, it is 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. Therefore, this data becomes very safe. 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.
?
1.2 Why is there blockchain innovation?
Human beings need to communicate during their activities, and communication is based on information. In the past, information circulation was not convenient enough to satisfy market participants. There is a demand for information, so intermediaries and centers are born. This centralized system has problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values ​​of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be activities involving centralized third-party intermediaries. Therefore, Internet technology that cannot establish global credibility has encountered great obstacles in its progress.——People cannot participate in any value exchange activities on the Internet in a decentralized manner. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing agencies, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, each country's legal currency has different credit values ​​and incompatible clearing systems, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let...>>

Question 2: What is blockchain? What does it mean in layman’s terms? What is China’s attitude towards blockchain? What can blockchain do? Blockchain, a great technology that accompanied the birth of Bitcoin, is currently being used in the financial field to significantly reduce transaction costs and improve efficiency, which is enough to excite Wall Street. However, this is just the tip of the iceberg. Its potential applications are very broad and will subvert every aspect of our lives in the future.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. One of the most basic characteristics of Bitcoin is decentralization. In recent months, financial giants have gradually begun to pay attention to Bitcoin's technology and used it in non-monetary fields, such as stock trading, election voting, etc. (1) Art Industry
Artists can use blockchain technology to declare ownership and issue numberable, 100% edition works in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
(2), Real estate industry
Use blockchain technology to solve various problems faced by everyone involved in real estate, including the naming process, land registration, agency intermediaries, etc.
(3), Insurance Industry
The financial industry has always been the most sensitive to advanced technology. Traditional banking and securities industry giants have been involved in the booming blockchain venture capital investment since 2014, with total global investment reaching US$1 billion within two years.
(4) P2P wallet
Personal assets can be traded through this P2P wallet in the future without going through any central institution, such as Bitcoin.
Most blockchains are in their infancy, mainly overseas. There are very few good domestic blockchain projects, so it is not recommended for any non-professionals to invest in blockchain projects. If you are very interested in blockchain technology and have a technical or financial background, it is recommended that you consider starting a business in this area. In terms of the blockchain protocol system, the lowest level is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platformTaiwan routing and basic algorithms; in the middle layer, it is necessary to solve some application interfaces and the issuance and verification of some credentials, including some industry platform services, big data analysis, etc. This is a very rough division, and it should also be There is a more detailed division; the top ones are some applications of blockchain, including some financial applications and other applications, the Internet of Things, etc.
Introduction to Bubi Blockchain
Bubi Blockchain has been focusing on the research and development and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has achieved substantial results in many aspects. Radical innovation has resulted in a number of core technological achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and interconnection technology between heterogeneous blockchains. wait. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.
A simple understanding of blockchain is a technology at the bottom of Bitcoin, which is also a peer-to-peer electronic cash system that can realize peer-to-peer value delivery. We should distinguish between Bitcoin, Bitcoin blockchain, blockchain and blockchain. Blockchain technology and other concepts. In countries with relatively developed finance in the past, finance and blockchain technology have a long history, and the legislation of digital currencies and blockchain networks is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own teams and conceptual technologies. Slowly, banks in various regions are also participating in digital currency discussions. The application and support of this technology are not only that. The influence of blockchain on enterprises is also huge. For larger domestic enterprises, Bubi Blockchain is also used in various equity, supply chain, points and other fields. Major domestic financial institutions and enterprises have taken a fancy to the new industry. value, they have developed their own blockchain platforms, and blockchain has instantly become a new innovative industry in China. In terms of overseas internationalization, the United States has already obtained 15 blockchain patents at the end of last year compared to China. Blockchain financial applications are entering a new stage in an all-round way. Various applications will become more and more in-depth, and related changes will also become more and more profound. It has attracted more and more attention and will form a huge new trend... >>

Question 3: What is blockchain technology? What exactly is blockchain? What is blockchain? 1. Data blockchain is an important concept in the Bitcoin financial system. It records transaction record data on the entire Bitcoin network, and these data are shared by all Bitcoin nodes. Through the data block, we can query each transaction record. A bitCoin trading history. 2. Example: There are three persons A, B, and C. All funds of A and B are kept by C. And every financial transaction must be recorded by C. Now assume that A and B each have 1 million in custody of C. Then: A spends 80,000 yuan to B, then C's account book record will subtract 80,000 yuan from A's name, and add 80,000 yuan to B's name. If B transfers 50,000 yuan to A, C will add 50,000 yuan to A's name and subtract 50,000 yuan to B's name in the account book. A spends 50,000 yuan to B, then C's account book record will subtract 50,000 yuan from A's name, and add 50,000 yuan to B's name. 3. The role of the data blockchain is similar to that of C’s account record book. It records the user’s ownership of Bitcoin and the records of all users’ Bitcoin transactions. It’s just that this “account record book” is recorded by the mining software of every Bitcoin miner on the network. If a Bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the network form Bitcoin’s distributed network database system. 4. The essence of data blockchain technology is a decentralized and distributed structure of data storage, transmission and certification methods. It uses data blocks to replace the current Internet's dependence on central servers, so that all data changes or transaction items are recorded. On a cloud system, the self-certification of data during data transmission is theoretically realized. In a far-reaching sense, this transcends the traditional and conventional information verification paradigm that relies on a center and reduces the cost of establishing global "credit." This point-to-point verification will produce a "basic protocol", which is a new form of distributed artificial intelligence and will establish a new interface and shared interface between human brain intelligence and machine intelligence.

Question 4: What is blockchain: This explanation of blockchain is more understandable. Blockchain refers to a technology that collectively maintains a reliable database through decentralization and trustlessness. plan.
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any 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 his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.
Blockchain technology has become the darling of the financial community in China and has become a hot topic. domesticThe Puyin Group has launched Puyin, a tea-based digital currency.

Question 5: Explain in an easy-to-understand manner what blockchain is. Blockchain can be understood as a database system in a sense. The development of blockchain can be divided into 1.0 and 2.0
1.0 is represented by Bitcoin, and its main application is virtual currency or digital currency application. The blockchain at this time can only be used for simple digital currency transactions.
2.0 is represented by the now popular ethereum (Ethereum) and the upcoming hyperledger. The blockchain at this stage can not only meet the corresponding digital currency transactions, but also use smart contracts to customize currency or asset transactions. If we use the database analogy, the emergence of smart contracts can be understood as allowing users to define functions or stored procedures in the database and call and execute them.
Different from traditional databases, the blockchain introduces consensus mechanism, incentive mechanism, p2p (network), hash and other specific elements, making it open, decentralized and non-tamperable. characteristic.

Question 6: What is blockchain? Can anyone explain it in simple terms? Blockchain is the underlying technology of Bitcoin. It is like a ledger that records all transactions. It is decentralized. What is decentralization? For example, when you buy something on Taobao, you place an order and pay in Alipay. Alipay will not transfer the money to the seller until you receive the goods. Alipay is the third party in that center. Without it, it means decentralization, just like buying things offline. If you pay with one hand and get the goods with the other hand, there is no third party.
The blockchain itself is a series of cryptographically related data blocks generated.
Look carefully to see if it looks like a ledger. The pieces one by one are blocks, and connected together they are the blockchain.
Many companies are developing this technology, including ours, and its prospects are incredible. For details, you can go to our official website and hope to adopt it, thank you

Question 7: What is blockchain technology? What is blockchain? How to explain the concept of blockchain? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
In the past six months, the concept of blockchain has gradually become popular in China, and a blockchain whirlwind has taken off in the financial circle. Blockchain has attracted the attention and favor of more and more people in the industry due to its unique technical advantages. Blockchain technology, which is decentralized (or multi-centered), highly transparent, cannot be tampered with, and has no single point of failure, is entering the field of vision of financial institutions and enterprises, at least in the past few years.Digital currency, payment and exchange, registration and settlement, digital assets, traceability and anti-counterfeiting, supply chain, Internet of Things and many other fields have moved from theoretical discussion to practical application.
"Blockchain" was first introduced with "Bitcoin" released in early 2009. Blockchain has become the basic protocol and technical application for the launch, recording, and circulation of Bitcoin. Although Bitcoin has been controversial since its inception and cannot even be regarded as a "currency" by governments and monetary authorities, the blockchain technology used in Bitcoin has been recognized by governments, including governments and monetary authorities. extensive attention.
Why has blockchain become a rapidly heating up hot technology and topic?
The most important of these may be that the launch of Bitcoin based on blockchain technology has opened up a new relationship with traditional society ( The exploration and attempt of new technologies and rule systems such as Internet user identity verification, wealth confirmation, transaction records, notarization and verification, which have little connection with offline) and are completely applied to the online world (online), provide people with the opportunity to adapt to the Internet society. Development provides alternative paths and unlimited imagination.
Judging from its application in Bitcoin, blockchain is a set of new network blocks (BLOCK, also called communities) formed by combining encryption technology with the Internet. Bitcoin configuration, netizen identity verification, and Bitcoin (value) confirmation formed by mining, Bitcoin transaction records, and extended encryption of Bitcoin cross-block flow (value transfer) (added block and transaction time identification, etc. Internet protocol rules and accounting (Ledger) system including block chain, full encryption, mutual authentication, etc., including factor) registration and verification. Precisely because Bitcoin is not a substitute for offline legal currency, but is issued and managed by non-legal currency authorities, mainly imitating the model of gold, and is completely new and decentralized protected and supported by basic Internet protocols and strict encryption technology. Internet currency (virtual currency) has thus formed a new set of currency rules and systems that are different from and not subject to real social laws, and can be bought, sold or exchanged with legal currency. It has been more than 8 years since Bitcoin was launched. There has been no record of funds or user information being stolen. Its security has been verified, and its efficiency and cost of fund settlement also have obvious advantages. This has made people's confidence in the blockchain technology used in Bitcoin continue to increase, and people have become more and more aware that although blockchain is a technology and protocol pioneered and applied by Bitcoin, the blockchain Chain is not the same as Bitcoin, and its application is by no means limited to Bitcoin. The application of blockchain can be decentralized or centralized; it can be a public chain model or a private chain model. Therefore, after Bitcoin, blockchain technology is also constantly developing and innovating, and constantly exploring new application fields, especially in the financial field.
The reason why blockchain is highly valued by more and more people is because of the InternetThe development and widespread application of Internet has caused more and more economic exchanges and transaction activities to be conducted online. The online world (or online society) is rapidly expanding, enriching and active, and online transactions must solve the identity verification and value of the parties involved. Efficiency and security protection issues in verification, transaction records, inspection and verification, etc., require strict intermediaries and agreements (rules or constitutions). In this regard, traditional thinking and customary practices are to follow the development trajectory of the transfer of offline transactions to online and push the common rules and practices of the real (offline) society to the online (network) society. However, in practice, it is increasingly It is difficult to adapt to the needs of online transactions.
For example, for the identity verification of the parties, the natural choice is to use the information on the identity documents protected by the laws of various countries as the basis, and then add account or transaction passwords, as well as facial recognition, iris, fingerprints and other biometrics to conduct online transactions. Verification, but this method first makes the citizen identity information in the cross-border interconnected online world subject to the administrative jurisdiction of real society... >>

Question 8: Easy to understand Explain clearly what is blockchain. The English name of blockchain is Blockchain. Block literally means block, block, and chain means chain, chain. Therefore, together they are translated into blockchain.
1. Use cryptography technology to encrypt and decrypt so that records cannot be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, Bitcoin’s blockchain has more than 60 gigabytes so far. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on the digitization of assets and has launched the digital currency crowdfunding platform Biying China.

Question 9: What is the so-called "blockchain"? Blockchain itself is a tool called decentralization and trustlessness. For example, when you graduate from university, the current practice is to have a certificate recognized and issued by an authoritative agency as your certificate. This setting is more troublesome, because this is a piece of paper, and paper can be forged, so there will be various gaps. The issuing authority is also a person, and there will be various gaps in the middle. As long as it is related to people, whoever There are various possibilities related to media. Blockchain provides a good opportunity. As soon as you graduate, you will have a record on the block chain.No one can change the record. This thing exists objectively. As a physical existence and as a data existence, the blockchain is born. In this case, anyone who wants to check where you graduated can easily solve the problem. This is similar to the big data often involved in social networking (WeChat) and payment platforms (Alipay, Yibao).

Question 10: What does blockchain mean? Regarding blockchain, I think you have already seen the concept on the Internet. Let me explain it based on my understanding!
First, let’s talk about its characteristics: 1. Openness and transparency 2. Decentralization 3. Anonymity 4. Information cannot be tampered with, eliminated 5. No trust cost
Blockchain is like a public ledger , everyone has the right to record and read, and everyone will jointly supervise to ensure its accuracy, and the recorded content will be permanently saved, and can only be added but not deleted! However, as the number of blocks continues to increase, costs will increase and efficiency will decrease. (I’m not sure whether technology can be used to make up for this. I hope someone who understands technology can point it out.)
Blockchain is divided into public chain, private chain, and alliance chain. Public chain: accessible to everyone, everyone has read and write permissions, completely open, transparent and decentralized. Private chain: Open to individuals or institutions, in which the owner of the private chain can set various permissions to make it partially centralized. Alliance chain: Open to specific organizations or groups, it is also "partially decentralized". According to the ledger at the beginning, members can view and transact, but cannot record and confirm bills, or require permission from the alliance. (The latter two do not have cost and efficiency issues)
Regarding blockchain, countries have begun to recruit talents in this area. For this, you can search online for "Central Bank Recruiting Digital Currency R&D Personnel". In addition, you can increase your understanding of blockchain by understanding its existing applications. What we usually refer to generally refers to public chains. Currently, those used abroad include Bitcoin, Ethereum and other domestic blockchains. Chain
1. Open and transparent: Every piece of data is verified by everyone and can be viewed by everyone at any time.
2. Decentralization: For example, when we shop on Taobao, we conduct transactions through the intermediary Taobao, and blockchain allows both supply and demand parties to directly contact each other for direct transactions through blockchain technology.
3. Anonymity: No personal privacy information is required to complete transactions on the blockchain, only your unique alphanumeric signature is required.
4. Information cannot be tampered with or deleted: Once the data has been verified and recorded, no one has the authority to modify it, let alone delete it!
5. No trust cost: The trust crisis in reality will not appear in the blockchain. Transactions in the blockchain do not require you to trust the other party. Only when both of you have enough "digital assets" to trade can it be carried out, and Under the supervision of the entire network, transactions will not be broken. If you have no idea about the cost of trust, think about itHow many intermediaries are there in your city, or simply think about Jack Ma, you will know how big the cost of trust is.
I am still learning more about blockchain. I am Li Ailin. If you have any questions, you can discuss and learn together!

⑹ What is the core content of blockchain

The core content of blockchain is the contract layer
1. Decentralization
This is blockchain The disruptive feature is that there is no central institution or central server, and all transactions occur in the client application installed on everyone’s computer or mobile phone.
Achieve point-to-point direct interaction, which not only saves resources, makes transactions autonomous and simplified, but also eliminates the risk of being controlled by centralized agents.
2. Openness
Blockchain can be understood as a public accounting technology solution. The system is completely open and transparent.
The account books are open to everyone, enabling data sharing and anyone can check the accounts. .
Blockchain is a transparent and shared general ledger. This ledger is open to the entire network. Once you get its public key, you will know how much money is in the ledger. Therefore, any value conversion is completely Interested people in the world can watch you, and the conversion is confirmed by the miners, so it is an Internet consensus mechanism.
3. Irreversible, non-tamperable and encrypted security
The blockchain adopts a one-way hash algorithm. Each newly generated block is strictly advanced in linear order according to time. The irreversibility and irrevocability of time will lead to any Attempts to intrude and tamper with data information in the blockchain can easily be traced, leading to rejection by other nodes. The cost of counterfeiting is extremely high, which can limit related illegal activities.
(6) The essence of decentralization of blockchain technology is to remove further reading:
1. Concept definition
What is blockchain? From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects [7].
Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database.
Two, features
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.
Openness. districtThe 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, so the entire system Information is highly transparent.
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.
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.
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

⑺ What is the essence of blockchain

Blockchain is essentially a decentralized distributed database. It is an innovative application model of distributed data storage, multi-center point-to-point transmission, consensus mechanism, encryption algorithm and other technologies in the Internet era.
In layman’s terms, the blockchain can be compared to a “ledger”. The traditional ledger is "centralized accounting" by one party. This new "accounting book" can be participated and shared by multiple parties on the Internet. Each participant can "accounting" and back up, and each backup is a "block". Each "block" is linearly connected to the next "block" in chronological order, and its structural characteristics make the record impossible to be tampered with and forged.
For example, if you are the one doing the accounting at home, and your parents give you a salary and let you record it in the account book, then because you are the only one keeping the accounting, you secretly spend more than ten yuan. Maybe they won't know, but now it's your parents who keep the accounts with you, so whether it's your father who wants to buy cigarettes secretly or you who want pocket money, every move will be clearly recorded in the account book.
