1. What is blockchain technology? Popular explanation of what blockchain is
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.Got a job.
This is the disadvantage of centralized accounting.
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.
2. What is blockchain technology
Blockchain technologyIt is a decentralized distributed database technology that can achieve data security, transparency, non-tampering and other characteristics. It is composed of many data blocks. Each data block contains the current timestamp and the hash value of the previous data block. Data storage and management are achieved by continuously adding data blocks.
The core idea of blockchain technology is decentralization. There is no central node control, but a decentralized network composed of many nodes to control the storage and circulation of data. In this kind of network, each node has the right to participate in the verification and storage of data. Any modification of data requires the consent of the majority of nodes in the network, which makes the blockchain technology non-tamperable and sensitive to inspection. Features such as centralization and transparency can ensure the security and credibility of data.
Blockchain technology can be applied to many fields, such as finance, Internet of Things, supply chain management, etc.
3. Is blockchain a technology?
Blockchain is not a single technology, but the result of the integration of multiple technologies. These technologies use new structures to Combined together, they form a new way of recording, storing and expressing data.
4. What is blockchain technology? What exactly is blockchain?
1. The so-called blockchain technology, referred to as BT (Blockchain technology), is also known as 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 computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated 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.
(4) Blockchain is a set of technologies. Extended reading:
Blockchain system consists of data layer, network layer, consensus layer and incentive layer. , contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms.
The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance of economic incentivesmechanism and distribution mechanism, etc.; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, which is the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain.
5. What is blockchain technology? What exactly is blockchain?
Blockchain technology is one of the top ten typical judicial technology applications on the Internet. 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. In fact, it is a decentralized database. Blockchain, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next data block.
Blockchain originated from Bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, and block technology. The concept of electronic cash system framework such as chain technology marks the birth of Bitcoin.
(5) Blockchain is a set of technologies. Extended reading:
The birth of blockchain:
The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. In the following years, blockchain became the core component of the electronic currency Bitcoin: a public account for all transactions. By using peer-to-peer networks and distributed timestamp servers, blockchain databases can be autonomously managed.
The blockchain invented for Bitcoin made it the first digital currency to solve the problem of repeated consumption. Bitcoin design has become a source of inspiration for other applications. On December 20, 2016, the Digital Currency Alliance-China FinTech Digital Currency Alliance and FinTech Research Institute were officially established.
6. What technology is blockchain?
1. The reason why blockchain is popular is because its functions are very practical. Blockchain can make information more fidelity . Blockchain technology can be applied to many fields and scenarios, including some social management scenarios, and it is necessary to further broaden the horizons of research and development of blockchain technology.
2. Blockchain is essentially a database technology, specifically a ledger technology. A ledger is a set of records that records changes in assets and transactions in one or more accounts. It is actually a database with the simplest structure. The running accounts we usually write down in small notebooks and the statements sent by the bank are all typical ledgers.
3. Blockchain is a distributed ledger with multi-party participation, and is called a technology "born to solve trust problems". The essential difference between the digital world and the physical world is that things in the physical world really exist and cannot appear or disappear out of thin air. However, data in the digital world can be deleted, altered or copied out of thin air without leaving any trace. But with blockchain technology, the digital world can be as real and credible as the physical world.
7. What kind of technology is "blockchain"?
Blockchain is an important concept of Bitcoin. Huobi cooperates with Tsinghua University PBC School of Finance to develop Internet finance. The "2014-2016 Global Bitcoin Development Research Report" released by the laboratory and Sina Technology mentioned that blockchain is the underlying technology and infrastructure of Bitcoin. It 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 distributed cryptographically to ensure that it cannot be tampered with or forged. Account book. 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 automated scripts to A new distributed infrastructure and computing paradigm that uses smart contracts composed of code to program and manipulate data.
Domestic blockchain application platforms include the asset custody system based on blockchain technology jointly developed by the digital currency crowdfunding platform Biying China, China Post and IBM.

Domestic blockchain application platforms include digital currency crowdfunding platform Biying China, ChinaAn asset custody system based on blockchain technology jointly developed by China Post and IBM.
Blockchain is a decentralized, distributed ledger system participated by nodes. The data stored on it cannot be forged or tampered with, and is open to the public. Transparent, the information and value recorded by each account at any point in history can be found on the blockchain. The characteristics of the blockchain protocol provide the necessary foundation for the execution of smart contracts. The contract can be automatically executed and trusted according to established conditions without the need for audit by any centralized organization.
Blockchain technology is the underlying core of the Bitcoin system. Its essence is a decentralized ledger. When people conduct transactions through the Internet, a new transaction will be recorded on the ledger, and this ledger is A decentralized ledger is jointly maintained by everyone in the network. People can see ongoing transactions at the same time, and control is not in the hands of institutions or individuals. Transactions cannot be tampered with or forged, and they will be permanently stored in the ledger.
For example, the Tongxin Huzhu blockchain mutual aid platform has four major characteristics in applying blockchain technology:
Openness and transparency
Openness and transparency, once all information recorded on the blockchain is recorded, it will be very It is difficult to tamper with and cannot be hidden, and users can check it at any time.
Democratic decision-making
Bottom-up decision-making, the blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decisions and jointly participate in major decisions.
Accurate execution of rules
Accurate execution of rules. The smart contract technology defined on the blockchain converts all rules into public and clear codes, which can be executed accurately and accurately. Once anyone is identified Cannot intervene.
Never downtime
Never downtime, the blockchain based on the public chain is not affected by any organization or individual. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist.
What is blockchain? Blockchain is a decentralized shared accounting technology that allows all parties involved to establish a trusting relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. Blockchain is still in its infancy. Many people have discussed with me how we can ensure both rights and privacy at the same time. Of course, we are just exploring now. We need fair content across the entire network and clear protection. This is what I can only say. So far, this is my arrangement for the future.
Blockchain concept? The idea of blockchain is to be completely decentralized and rely on decentralized justice. In that case, theoretically the cost will drop a lot, proving that real assets and property rights can directly correspond to each other on the Internet. Solve the problems of decentralization and asset ownership that were not solved by the first generation of Internet informationThe question is, how big a role does big data play in financial innovation now? Only by registering big data can we know who it belongs to. In fact, this has always been a problem that we cannot solve now. This is not a small problem. If there is a technology in the capital market that makes the property rights of things that were originally unclear clear, that will be a big problem for us. The entire market is undergoing a huge transformation.
What is blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanisms. This still cannot completely solve certain problems. To give a simple example when it comes to user privacy, I have a piece of data placed on the machine. The partner comes over and makes an insurance analysis to analyze the cooperation. There is a risk here for Or not, can we deal with it or clarify the property rights of the laboratory, and then clarify the processing rights and data rights. The common products produced by everyone are common to everyone. If we need to divide different things, how to price them and how to divide them? In addition to the technology of blockchain and a decentralized database, when it comes to the above mentioned tasks, it is another issue, and then there is the issue of pricing and the market mechanism. All fields have proven to recognize this rule, so this I think blockchain is a very good core technology, but it cannot cover all problems.
Introduction to Bubi Blockchain
Bubi Blockchain is mainly positioned to provide commercial-grade blockchain infrastructure services, which mainly includes building a blockchain system and building on top of the blockchain system. A support system with high expandability. On top of this support system are applications from all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, a team of more than a dozen people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi Blockchain chooses points has something to do with the market's promotion method. As we all know, blockchain is a technology that is very suitable for the issuance and trading of digital assets. Points are a digital asset that is naturally legal and compliant, and has a small impact because of its small amount. Therefore, it is a very suitable choice to use points as your first attempt at digital asset issuance. Issuing points based on the blockchain can indeed bring great help to the circulation and mutual exchange of points.
What is blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to reducing property transfer costs, blockchain technology can also be applied to various fields involving company stocks, financial derivatives, and points programs of commercial institutions. The blockchain community is currently focusing on promoting the wider application of this technology in the field of financial assets. Relatedly, various platforms that are still under development have also received very considerable investment.
Blockchain concept? Structurally or by definition, these things are very different. The U.S. dollar, or any currency, from a typical definition, is primarily used as a medium of exchange or store of value for economic activities. Within the geographical scope where a certain currency circulates, people in the region reach a consensus on the use of this currency, making it convenient for everyone to use the same currency to purchase goods or services (the transaction medium function of currencyable). There is a responsibility to manage the currency through monetary policy in order to ensure the preservation of the value of the currency and avoid the occurrence of inflation (the store of value function of currency). In today's world, almost everyone uses some form of currency in their daily lives.
What is blockchain? Even developers within the blockchain community often easily overlook the big picture mentioned above. There are many competitive projects in the blockchain community, and they are also full of various disputes about the evolution direction of blockchain technology. Over time, some projects in the community will be successful, and others will not be so lucky. Things will not always develop in the direction we expect, but no matter how these projects in the early blockchain community develop, one thing is very clear, that is, blockchain technology has brought us at least A revolutionary function: Blockchain technology will greatly reduce the cost of financial property transfer, and blockchain will be used to control, manage and transmit financial property.
What is blockchain? Blockchain concept? After a certain application analysis, we return to the starting point. The definition of this blockchain technology will surely become more and more abundant with the expansion of applications, and people will discover more mysteries of blockchain technology.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the basis for Bitcoin. underlying technology. 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. .
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet information. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. The lightweight Bitcoin wallet uses online confirmation, which means it does not download the blockchain data to the device storage.
Many of Bitcoin’s altcoins also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.
Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “genesis block”.
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left an unchangeable sentence in the genesis block:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor Darling was forced to consider a second bailout of the banks. moment of crisis, this sentence was the headline of the Times' front-page article that day.
With the blockchain’s timestamp service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service and store it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
Chongqing Jinwowo analyzed: Blockchain is actually a decentralized distributed ledger database.
How popular is blockchain technology?
Blockchain technology makes DAC possible. DAC is something that can fundamentally subvert the organizational model of human society. I believe that its impact on society will surpass the Industrial Revolution and become the most profound change that the Internet has brought to the world.
The essence of blockchain technology is a method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It replaces the current Internet with data blocks (Block). The road's reliance on the central server enables all data changes or transaction projects to be recorded on a cloud system, theoretically achieving self-certification of data during data transmission.
Blockchain technology can be applied to many industries:
Art industry
Ascribe allows artists to use blockchain technology to declare ownership, Issue numberable, 100% editions of your work 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.
Legal Industry
BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property rights. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
Development Industry
Colu is the first company to allow other companies to issue digital assets. They can "tokenize" various assets and have a profound impact on many people. While the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu's tokens can be configured in various states and types, and can be detached or traded.Return to this system and be able to store the data on the BitTorrent network when storing it on the blockchain becomes too large.
Online Mutual Aid Industry
Tongxin Mutual Aid is the first blockchain online mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, it eliminates the shortcomings of the traditional online mutual aid model. Establish an open and transparent new online mutual aid platform.
Aite Cat is a virtual pet game produced under blockchain technology. This virtual cat is similar to Internet Letts Dog, 360 pet cat, and NetEase’s Planet are all the same type of blockchain virtual products. The difference between Aite Cat is that the entire cat design adopts a 3D three-dimensional effect, making the cat’s The display is no longer a single picture, allowing the cat to move, which increases the fun of the cat.
What technology is the Huangbao blockchain system?The Huangbao blockchain is a powerful decentralized loop intelligence system. The Huangchain chain is referred to as HUANG. It is the first to be used in financial services, advertising media, games and entertainment, various life applications and other fields, becoming a blockchain 3.0 The representative virtual currency of the era, Media Chain 3.0 technology has the core characteristics of being safer, more efficient, more flexible, and more open. The widespread application of its technology will surely trigger new forms and new ideas in the global media industry, which can Create convenient services and new concepts, which marks a new economic era before the public.
9. What kind of technology is blockchain technology?
Blockchain is a distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer New application models of technology. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is the underlying technology of Bitcoin, like a database ledger that records all transaction records. This technology has gradually attracted the attention of the banking and financial industries because of its safety and convenience.
In April 2018, a group of scholars from Oxford University announced the establishment of the world’s first blockchain university, Woolf University.
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is distributed cryptographically to ensure that it cannot be tampered with or forged. Account book.
Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure the security of data transmission and access. A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and manipulate data.
