2. Direct to Digital Expo丨Blockchain Standardization and Application Innovation Summit released three innovative results

Hebei Provincial Party Committee Cyberspace Affairs Office Chief Engineer Zhang Ping introduced that blockchain is one of the hot spots of this expo. The "Hebei Province Blockchain Special Action Plan (2020-2022)" released by Hebei Province last year clarified the development of blockchain technology and industrial applications in Hebei Province. Goal - By the end of 2022, there will be 20 leading companies and leading companies in blockchain-related fields in Hebei Province, cultivate a number of blockchain application products, and strive to create 1-3 nationally renowned blockchain brands and form 3 regional The influential blockchain industry cluster park, the blockchain industry competitiveness ranks among the top in the country. To this end, Hebei Province is committed to introducing well-known domestic and foreign enterprises, gathering the most advanced technology, the most cutting-edge innovative concepts, and the most high-end human resources to cultivate innovative forces for the development of Hebei's blockchain industry.

"Hebei Provincial Characteristic Agricultural Products Blockchain Traceability Platform" was jointly developed by the Institute of Applied Mathematics, Hebei Academy of Sciences and Huaye Hebei Co., Ltd. Wang Zhiqiang, deputy director of the Institute of Applied Mathematics of the Hebei Academy of Sciences, introduced that the platform fully integrates blockchain with big data, Internet of Things, artificial intelligence and other technologies to realize the full chain traceability of production, logistics and sales information of specialty agricultural products, making production Operators, the public and regulatory authorities can participate together to build brands, enhance product value, and promote high-quality development of the agricultural economy.

It is reported that the “Hebei Province Specialty Agricultural Products Blockchain Traceability Platform” has three most prominent features:

First, one vote, one code, and object code locking. Intelligent identification and matching of business entity information and sales documents effectively solves problems such as multiple data sources, poor quality, and inconsistency between upstream and downstream.

Then there is the whole-chain evidence storage and accurate traceability. With the traceability code as the carrier and responsibility and flow management as the core requirements, agricultural product circulation data, electronic vouchers and other information are uploaded to the chain to achieve functions such as data non-tamperability and transaction traceability, and improve data throughput through the standardization of data storage and exchange. Key performance indicators such as volume and system response speed.

The third one is multi-source fusion and targeted regulation. On the basis of the blockchain system, for the characteristic agricultural product industry chain, a fusion model of production, circulation and inspection big data has been established to achieve targeted supervision and intelligent decision-making based on big data analysis, and comprehensively enhance the brand of on-chain products. Credibility.

"After three months of trial, the platform has been connected to 212 agricultural product trading markets, 9807 online merchants, and 3484 online varieties, showing strong application demand and development potential." Wang Zhiqiang introduced, Hebei The Provincial Academy of Sciences is also exploring another high-quality route, cooperating with the Julu County Government to promote the "One Flower Supports Hundreds of Industries" project, using "blockchain empowering agriculture" as the entry point to create an agricultural digital estate, and then drive the county's first, second, and third Integrated development of industries will ultimately achieve the goal of “one flower blooming and hundreds of industries prospering”.

This Blockchain Standardization and Application Innovation Summit is hosted by the China International Digital Economy Expo Organizing Committee and hosted by the China Electronics Technology Standardization Institute, the Software Institute of the Chinese Academy of Sciences, and the Hebei Academy of Sciences.

3. You have to know the operating principles and development of blockchain!

1. Why is there innovation in blockchain?
The starting point of the first generation of the Internet is the TCP/IP protocol, which implements a unified format for peer-to-peer transmission of information by all nodes on the network. Open code. However, the impact of such an uncomplicated innovation on mankind is epoch-making. It has programmed, agreed, and enforced the basic values ​​required by a unified global market: "freedom, equality, and fraternity." Then the STMP email protocol, HTTP domain name protocol, etc. were derived, achieving low-cost and high-efficiency global information transmission in a decentralized manner. As Alibaba Vice President Gao Hongbing said:
"The Internet is to eliminate the (information) supply chain that has very low value and high cost - it is open, interconnected, peer-to-peer, globalized, and decentralized."
We know: The essence of the market is also decentralized. It automatically executes the decentralized agreement of "equivalent exchange". Just as Nobel Prize winner Ronald Coase summed up: "The market economy is based on two On the basis of deep cognition: admitting ignorance and tolerating uncertainty." Adam Smith also described the market as: "the invisible hand"! Therefore, the market must require the low-cost flow of information decentralization, and the Internet has adapted to the global Under the general climate formed by the unified market, it turned out to be.
However, the first generation of Internet decentralized solved the problem of low-cost and efficient transmission of information, but it did not solve the problem of credit of information. Therefore, what the second-generation Internet must break through is: how to establish global credit in a decentralized manner so that value transfer can be carried out at low cost and with high efficiency.
So what are the problems with the original centralized credit system? As we all know: centralized credit, such as the legal currencies of various countries, has different credit values, and the clearing systems are also incompatible, which adds a lot of cost to global trade. The current global credit system centered on the US dollar has a "Triffin Paradox" in its mechanism (the essence is that a country's legal currency cannot simultaneously resolve the conflict between its own economic interests and global economic needs). Therefore, in 2009, the Governor of the Central Bank of China, Zhou Ogawa called for the creation of a super-sovereign storage currency. In the same year, Satoshi Nakamoto published the first-generation blockchain source code online - "Bitcoin"”.
2. How does the blockchain system operate?
First of all, Satoshi Nakamoto knew very well that establishing a credit system for payment must solve the problem of preventing “double payments”, that is, not counterfeiting coins. Centralized The credit system relies on the state machine to prevent counterfeit coins. What about "Bitcoin"? Satoshi Nakamoto's great innovation is to "timestamp" each transaction. Every ten minutes a block (equivalent to Network account book), and correctly timestamp the entire network transactions for these ten minutes. The question is who will stamp it? Satoshi Nakamoto did not assume that all people on the Internet are Lei Feng. He agreed with Adam Smith’s point of view: the market People are greedy. He asked the so-called "miners" to compete for the accounting rights of each block for ten minutes. The rules of the competition are to correctly record the accounting and at the same time solve the SHA256 problem. Who can prove that their computer calculation With the fastest power (the so-called PROOF OF WORK mechanism), he can compete for the legal accounting rights of these ten-minute blocks and get a reward of twenty-five bitcoins. This is the so-called "mining" process. In fact, It is to establish a network-wide general ledger - the decentralized credit process of the blockchain, so the more essential function of the miner is "bookkeeper"!
Satoshi Nakamoto described this in detail in his Bitcoin white paper The process of establishing the credit system:
The first step: In order for the entire network to recognize it as valid, each transaction must be broadcast to each node (node: that is, the miner);
The second step: Each miner node must Correctly timestamp each transaction in these ten minutes and record it in that block;
Step 3: Each miner node must compete for this ten-minute block by solving the SHA256 puzzle. Legal accounting rights, and strive to get a reward of twenty-five Bitcoins (fifty Bitcoins every ten minutes for the first four years, decreasing by half every four years);
Step 4: If a miner node unlocks After solving the SHA256 problem of these ten minutes, he will publish all the timestamp transactions recorded in his ten-minute blocks to the entire network, and they will be verified by other miner nodes in the entire network;
Step 5: Verification by other miner nodes in the entire network The correctness of the accounting of this block (because they are also stamping the accounting at the same time, but they have not competed for the legal block accounting rights, so there is no reward). If there is no error, they will compete for the next one after the legal block. block, thus forming a legal accounting single chain of blocks, which is the general ledger of the Bitcoin payment system - the blockchain.
Generally speaking, each transaction must be confirmed six times by blocks , that is, six ten minutes of accounting before it can finally be recognized as a legal transaction on the blockchain. The following is the accounting format of Bitcoin:
So the so-called "Bitcoin" is such a billing system: it includes all The owner uses the private key to electronically sign and pay to the next owner, and then the "miners" of the entire network stamp the time stamp to form a blockchain.
3. What innovations are there in Bitcoin's blockchain finance?
Gold-like, try to build a global Internet to go to ChinaCentralizing credit makes it possible to transfer value at high speed and low rates across the entire network (currently the rate for each transfer is one ten thousandth);
The total amount of currency is agreed upon by the cryptographic protocol;
Compared to Gold, digital currency is infinitely divisible;
Currency value can be built on a large number of P2P transactions;
Full transparency of financial management (every transaction can be checked on the blockchain).
Bitcoin’s blockchain-wide accounting system has established a market value of US$10 billion, the highest on the global Internet. Therefore, Wu Xiaoling, dean of Tsinghua PBC School of Finance, pointed out: The blockchain experiment established distributed credit, which is an upgraded version of Internet TCP/IP, upgrading from information transmission to value transmission;
4. Bitcoin’s blocks What are the inherent flaws of the chain system?
Bitcoin’s blockchain system has had successes since it was open sourced on the Internet in 2009, but it also shows some inherent flaws that are difficult to overcome:
The total amount cannot be adjusted at any time As the market situation changes, it will inevitably rise and fall sharply;
Mining is high-carbon. Only less than 1% of miners can compete for the accounting rights of blocks of less than ten minutes, and more than 99% of other miners participating in the competition have the computing power. Waste;
The annual inflation of about 10% has greatly increased the cost of the Bitcoin financial ecology, and even threatened her survival;
As a decentralized self-organizing DAC system, the operating costs of the accounting and issuance functions are too high high.
As a global payment system, its efficiency is far from meeting the actual requirements of global trade. The Bitcoin network currently confirms a maximum of 7 transactions per second. In comparison, Visa's network system can process 10,000 transactions per second at the fastest, and Alipay's record is 80,000 transactions per second on Singles' Day in 2014!
5. Block The development of chain technology 2.0:
As the 2.0 upgrade and development of blockchain, it first focuses on solving the high-carbon mining of Bitcoin accounting:
When we discuss how to overcome the high carbon of Bitcoin mining and accounting Professor Liu Taoxiong from the Tsinghua Institute of Economics pointed out that mining competition relies on computing power. In the end, only one company competes for the legal accounting rights, and the other 99% of the miner nodes are mined for nothing, which is a waste of resources. It is obviously unreasonable. If The whole network transparently knows the legal accounting rights of the next block, and it is randomly generated in the entire network, which eliminates the high carbon cost of competitive accounting! After hearing this, we all praised Professor Liu for his brilliant idea, because the second generation is now more successful. Coin NXT has this mechanism. Their white paper is called "Transparent Forging". However, the probability of the accounting rights going to someone is directly proportional to the NXT token holdings in each miner node wallet. This is called the proof of equity mechanism ( PROOF OF STOCK). Of course, this also triggered a debate about the unfairness of NXT’s distribution of tokens to early investment developers!
RIPPLE is a semi-decentralized blockchain solution that uses “trusted gateways” to conduct block operations. Chain accounting, its credit is based on the consensus accounting that these gateways will not do evil at the same time (consensus ledger) agreement.
The most ambitious attempt is Ethereum, which combines blockchain technology with Turing completeness, hoping to develop a basic platform that can support the construction of various blockchain systems in the future. The development of various credit currencies, digital assets, smart protocols and even financial derivatives. The system design is to unify blockchain accounting on the ETHERUM platform and be used by all developers. Maybe their official version will be released in the near future.
6. Possible applications of blockchain innovation in other fields:
Now, blockchain’s attempts to establish decentralized credit are no longer limited to the financial world, but have attracted attention from all fields of society, especially in At present, some of China's central credit institutions, such as the "Red Cross", are in a "collapse" situation. Blockchain can provide a new way of thinking and technical options for social management. The following are some new developments and related discussions we have learned about:
The combination of blockchain and the Internet of Things unifies digital assets and atomic assets, smooths the difference between consumer assets and cash assets, expands public credit, and accelerates value circulation; (IBM-Samsung)
Built on the blockchain Intellectual property protection system, accounting for the use of intellectual property across the entire network, and establishing a global advertising market;
Whether blockchain can provide technical support for the issuance of protocol-based cryptographic currencies by emerging economies along the Belt and Road;
Block Chain + cloud computing can develop into a decentralized self-media and community system;
Blockchain can build a decentralized equity crowdfunding system, allowing innovative projects to enter the circulation field in advance;
Blockchain can develop Develop a fully transparent financial management system;
Blockchain supports the establishment of a global decentralized corporate organization.
In short, in this era when credit has become a scarce resource, the technological innovation of blockchain, as a distributed credit model, provides new opportunities for finance, social management, talent evaluation and decentralized organization construction in the global market. All provide a broad development prospect.

4. What 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. 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 an important concept of Bitcoin. It is essentially a disintermediated 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 its information (anti-counterfeiting) and generate the next block.

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, 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; a total ofThe knowledge layer mainly encapsulates various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and intelligence Contracts are the basis for the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.



Isn’t this sentence very awkward? It doesn’t matter if you don’t understand, let’s use an analogy.

Imagine everyone has a magical little notebook. When a transaction occurs between two people, the transaction is recorded in your two notebooks without any intermediary, including a notary. The most amazing thing is that this transaction record will be automatically copied to everyone's notebook soon, and everyone can see it. When more than half of the small books have records of this transaction, the transaction will officially take effect.

After the transaction takes effect, you cannot tamper with the record privately. Even if you can tamper with the records in your own notebook, unless you can tamper with the records in most people's notebooks at the same time (which is almost impossible), the transaction will still be valid.

So there is no need for a third-party trusted intermediary, and such transactions can proceed with confidence because everyone else is automatically notarizing the transaction. Do you want to default on the payment after buying something? no way. Likewise, you don’t have to worry about the other party defaulting on your account.

Because blockchain has the characteristics of large-scale scalability, open and transparent data, and non-editable data, it can especially effectively solve the problem of trust among strangers, so it can be extended to all fields that can be digitized. For example, digital currency, payment settlement, digital bills, proof of rights, credit reporting, government services, medical records, etc.

5. What are the current development prospects of blockchain technology

Research strength has increased and research results have been significant

As of the end of 2019, my country’s blockchain research The number of institutions has reached 97. In addition, domestic universities have deployed blockchain technology research, strengthened the innovation of blockchain technology theoretical knowledge, and improved the blockchain technology research and development capabilities of universities. By the end of 2019, there were 24 universities in my country participating in strengthening blockchain technology research and development.

6. Popular explanation of what blockchain is

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: Go Centralized 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 Conduct payment transactions directly 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 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 pass a series of data blocks (blocks) generated by using cryptographic methods to associate each data block.The block contains all information exchange data of the system within a certain period of time, and a data fingerprint is generated to verify the validity of its information and link 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 credit 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 eachNational legal currencies have 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 layer is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platform routing and basic algorithms; in the middle layer, some application interfaces and some credentials must be solved Issuance and verification, including some industry platform services, big data analysis, etc. This is a very rough classification, and there should be more detailed classifications; the top ones are some applications of blockchain, including finance Some applications and other aspects ofSome applications, 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 look at the history of Bitcoin transactions. 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 will record in the account book, subtract 80,000 yuan in A's name, and put it in B's nameAdded 80,000 yuan to his 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. Domestic 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 Represented by Bitcoin, the 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. It has at least been used in digital currency, payment exchange, registration and settlement, Digital assets, traceability and anti-counterfeiting, supply chain, Internet of Things and many other fields have moved from theoretical discussions to practical applications.
"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. exhaustAlthough 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 brand-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 fully applied in 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 valued highly by more and more people is because the development and widespread application of the Internet have caused more and more economic exchanges and transaction activities to be conducted online, and the online world (or online world) society) is rapidly expanding, enriching and active, and online transactions must solve the efficiency and security protection issues of the parties' identity verification, value verification, transaction records, inspection and verification, etc., and require strict intermediariesand agreement (rules or constitution). 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. The blockchain provides a great opportunity. As soon as you graduate, you will have a record on the blockchain. No one can change this record. This thing exists objectively. You, as a physical existence , and then as a data existence, the blockchain was born. In this case, anyone who wants to check where you graduated can easily solve the problem. This is different from the usual social networking (WeChat) and payment platforms (Alipay,There are similarities with the big data often involved in 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, just think about how many intermediaries there are in your city, or just think about Jack Ma, and 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!

7. The future development prospects of blockchain

1. Blockchain has become the forefront of global technological development and opened up a new track for international competition. Blockchain will become a new key infrastructure to further accelerate the development of the digital economy, lead a new round of global technological change and industrial change, and become the "source" of technological innovation and model innovation. The world's major developed countries will further pay attention to blockchain technology, intensively introduce relevant policy plans, increase industrial support and guidance, and enhance the competitiveness of their country's blockchain technology and industry.
2. The digital currency bubble gradually cools down. With the spread and popularization of the concept of blockchain technology, more and more people will realize that Bitcoin is not the same as blockchain, and various air coins will be gradually eliminated. Blockchain technology innovation will return to a more rational track. Technical features such as decentralization, multi-party collaboration, and anti-calculation tampering will be highly valued by relevant industries. Some industries with strong innovation capabilities will continue to emerge with blockchain applications that have been transformed based on industry characteristics.

8. What is the most important thing about innovation in the blockchain field?

Technology is the first indicator of the long-term healthy development of all blockchain projects, so making value in the blockchain field Investment, the entrance to EVOLAB is technology. Only by understanding the importance of project technology can we solve the core aspects of value investment and find good projects.
