㈠ What exactly is blockchain and which blockchains have physical applications
What is blockchain?
Official definition: Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission consensus mechanism encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Vernacular understanding: A block is to package all the data generated within a time period in chronological order. Generally, the length of a block is 10 minutes, which means that within 10 minutes, all the data on the Internet will The data is packed into a complete package, and this complete data package is called a block. The blockchain links these data packages in order to form a structure, and cryptographically ensures that it cannot be tampered with or forged to form a distribution. ledger, this is the blockchain.
It seems that everyone has a preliminary knowledge and understanding of the blockchain. So whether the blockchain has any practical application in daily life, the answer is yes, the current practical application There are mainly the following aspects. Of course, I may not know some of them. Friends are welcome to leave messages to add.
Financial Industry
Blockchain should be used the most in the financial industry.
For example, in May 2017, OMG (Omise Coin) announced that it would cooperate with Alipay to launch an electronic wallet, integrating the "Alipay" payment solution into its own payment service suite to help local electronics in Thailand. Business merchants accept online payment transactions from Chinese tourists.
Another example is PPT, which is a financial transaction system for bills based on blockchain.
Gaming
The gambling industry entered the blockchain probably last year. Why does gambling favor blockchain? Because blockchain provides a relatively fair betting system. Why? It is relatively fair. As can be seen from the previous introduction, the blockchain cannot be tampered with or forged.
For example, WICC (WikiChain) can realize rich application scenarios such as asset issuance, betting applications, copyright traceability, mutual insurance, decentralized exchanges, and cross-border settlement.
For example, the STX (King of Fighters Token) stox application is designed to provide the full functionality of a prediction market application without the need for any central server. Prediction markets require functions such as event planning, market production, providing information and analysis to traders, reporting event results, and of course collection and payment.
I believe that if the current lottery industry is built on the blockchain, people will become more and more enthusiastic about buying, because there are too many insider tips that make people give up.
Internet of Things
The Internet of Things still has many applications on the blockchain, because the traceability and immediacy of blocks are very suitable for this industry.
For example, DATA is the concept of the Internet of Things. It is a decentralized p2p network. The data source can be connected to any node in the entire networkConnect, then publish the data and the network will send it to subscribers immediately. Horizontal scalability is achieved through sharding pattern. This timeliness and accuracy are very important in IoT applications.
Game industry
For example, GTC (G coin) is a decentralized digital asset based on Ethereum erc20 issued by Game Global. G coin is committed to becoming a universal number in the global game industry. Monetary standards.
For example, MANA is a distributed shared virtual platform. On this platform, users can browse and discover content and interact with other people and entities. Users can also claim ownership of virtual territories through a blockchain-based land ledger. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including static 3D scenes to interactive systems such as games.
There are many other industries. The emperor did not list them one by one, but listed a few representative ones. What is the purpose? It shows that the blockchain is definitely not just a currency transaction, it is a real implementation project, and it is a product of the changes of the times with real practical uses.
The development of human society is actually like the blockchain, it is irreversible and unstoppable. As far as I feel, the blockchain will enter thousands of households sooner or later. Regardless of whether it is bull or bear, hold it in your hands. Value coins and Flush have started quoting digital currencies, which shows that society is accepting it step by step. The power of social development cannot be blocked by any country or person.
㈡ What kind of technology is "blockchain"?
What kind of technology is "blockchain" Blockchain is an important concept of Bitcoin. The "2014-2016 Global Bitcoin Development Research Report" released by the Internet Finance Laboratory of Tsinghua University PBC School of Finance and Sina Technology mentioned that blockchain is the underlying technology and infrastructure of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. 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 utilizes automated Smart contracts are composed of scripts that program and compute data in a new decentralized infrastructure and normalize computing.
Domestic blockchain application platforms include digital currency crowdfunding platform Biying China, China Post and IBM, which are based on blockchain technology.asset custody system.
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 trust 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. It has solved the problems of decentralization and asset ownership that were not solved by the first generation of Internet information. How big is the role of big data in financial innovation now?use? 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 function of currency as a medium of exchange). Responsibility for managing money through monetary policymanagement in order to ensure the preservation of currency and avoid the occurrence of inflation (the value storage 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. In a time of crisis, this sentence was the headline of a front-page article in The Times 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. Although the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be configured in various states and types, and can leave and return to the system. , and when stored on the blockchainWhen the data is too large, the data can be stored on the BitTorrent network.
Internet 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 uses 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 definitely trigger new forms and new ideas in the global media industry, and can Create convenient services and new concepts, which marks a new economic era before the public.
㈢ What is blockchain and how to introduce blockchain in a simple and easy-to-understand manner
Many people don’t know what blockchain is. Here I will give you a detailed introduction to blockchain. Chain is a new technology that subverts the old model. Just like people tend to ignore the invisible but indispensable oxygen, people often ignore the most important thing in the market economy, which is trust. Without trust, no transaction can be established.
In addition, different races, nationalities, cultures, religious beliefs, etc. will form a trust gap. Due to the lack of mutual understanding and necessary trust between strangers, transactions are difficult to occur. The market economy emerged in large numbers among strangers. The emergence and development of the market economy lies in the birth of a new mechanism, which solves the problem of trust between strangers.
The concept of blockchain was first proposed in a paper written by Bitcoin founder Satoshi Nakamoto in 2008. Blockchain can be understood as a kind of public accounting. Technical solution: All data will be open and transparent, without the need for a central server as a trust intermediary, thus ensuring the authenticity, immutability and credibility of information on a technical level. The immutability of data is very important.
Because the blockchain has the technical characteristics of large-scale expansion, open and transparent data, and because the data of each client is consistent, even if some clients are destroyed, it will not affect the reliability of data security. In particular, it can effectively solve the problem of trust between strangers, so this technology can be extended to all areas that can be digitized, such as digital currency, payment clearing, digital currency, etc.Digital bills, proof of rights, credit reporting, government services, medical records, etc. If blockchain technology develops, it will be closely related to everyone in the future.
㈣ The development of blockchain applications has gone through several stages
Principles of blockchain technology
By definition, blockchain is a time-based It is a traceable chain data structure that combines continuously generated information blocks in a sequential manner. It is a distributed ledger that cryptographically ensures that the data cannot be tampered with or forged.
Blockchain is an innovative application formed by combining asymmetric encryption algorithms, consensus mechanisms, distributed storage, point-to-point transmission and other related technologies in new ways. The biggest advantage and direction of blockchain technology is "decentralization". By using cryptography, consensus mechanisms, game theory and other technologies and methods, decentralized credit-based decentralization can be realized in a distributed system where network nodes do not need to trust each other. Peer-to-peer trading.
The excellent characteristics of blockchain come from its unique technical foundation. A basic blockchain must at least consist of three parts: data layer, network layer and consensus layer.
The data layer provides a unique data structure to ensure security, and uses asymmetric encryption, hash function, Merkle tree and other technologies to encrypt data to ensure data security and provide the basis for blockchain applications;
p>
The network layer realizes the core idea of decentralization through the P2P network. In the BitTorrent network, each node is both a data receiver and a data sender.
In blockchain technology, the public key is similar to a seed. With the public key, you have an identity that can speak in the network. At present, the consensus mechanisms mainly include PoW, PoS and DPoS consensus mechanisms. If you want to attack the blockchain, you must provide greater computing power than Zhu Lian. The benefits obtained are far less than the cost of the attack. The PoW consensus mechanism competes through computing power. Ensure the security and decentralization of the system.
——For more data and analysis, please refer to the "Forward-looking Industry Research Institute" China Blockchain Industry Market Prospects and Investment Strategic Planning Analysis Report".
㈤ An introduction to the principles and applications of blockchain technology
1. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains The information of all Bitcoin network transactions in the past ten minutes is used to verify the validity of its information (anti-counterfeiting) and generate the next block. It is the underlying technology of Bitcoin, like a database ledger that records all transaction records.
2. Broad definition: Use encrypted chain structure to verify and store data, use distributed node consensus algorithm to generate and update data, use automated script code (smart contract) to convert and operate data A new decentralized infrastructure and distributed computing paradigm.
3. Narrow definition: combine data blocks into a specific chain in chronological orderData structure, and cryptographically guaranteed decentralized shared accounts that cannot be tampered with or forged.
4. Characteristics of blockchain: Decentralization: The verification, accounting, storage, maintenance and transmission of blockchain data are all based on distributed system institutions, using pure Mathematical methods rather than central structures are used to establish trust relationships between distributed nodes, thereby forming a decentralized and trustworthy distributed system.
5. Time series data: Blockchain uses a chain block structure with timestamps to store data, thereby adding a time dimension to the data and having strong verifiability and traceability.
6. Collective maintenance: The blockchain system uses a specific economic incentive mechanism to ensure that all nodes in the distributed system can participate in the verification process of data blocks, and select specific nodes through a consensus algorithm Add new blocks to the blockchain.
7. Programmable: Blockchain technology provides a flexible script code system to support users in creating advanced smart contracts, currencies or other decentralized applications.
8. Safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, and at the same time uses the powerful computing power formed by consensus algorithms such as workload proof of each node of the distributed system. To resist external attacks and ensure that blockchain data cannot be tampered with or forged, it has high security.
9. Blockchain application scenarios: Digital currency: Represented by Bitcoin Damin Coin, it is essentially a digital currency generated by a distributed network system. Its issuance process does not rely on a specific centralized institution. .
㈥ What is wrong with the following statement about blockchain evidence?
Blockchain is a temporary, irreversible generation of encrypted data superimposed in chronological order. What is wrong with the following statement about blockchain evidence is that blockchain is a temporary, irreversible generation of encrypted data superimposed in chronological order. Blockchain is a chain composed of blocks one after another. Each block stores certain information, and they are connected into a chain in the order of the time they were generated.
㈦ What is the six-layer model of the blockchain?
The blockchain has a total of six levels of structure. These six levels of structure from bottom to top are: data layer, network layer , consensus layer, incentive layer, contract layer, and application layer.
1. Data Layer
The data layer is the bottom layer of the six-level structure of the blockchain. We can understand the data layer as a database, but for blockchain, this database is an immutable and distributed database, which is what we call a "distributed ledger".
On the data layer, that is, on this "distributed ledger", the data information on the blockchain is stored, encapsulating the blockchain structure of the block, asymmetric encryption technology, hash algorithm and other technologies Means to ensure the security of data when it is disclosed to the entire network. The specific approach is:
In the blockchainOn the network, nodes use consensus algorithms to maintain the consistency of data in the data layer (that is, this distributed database), and use asymmetric encryption and hash algorithms in cryptography to ensure that this distributed database cannot be tampered with and traceable. .
This constitutes the lowest level data structure in blockchain technology. However, it is not enough to have a distributed database. The data information in the database also needs to be shared and exchanged. Next, we introduce the upper layer of the data layer - the network layer.
2. Network layer
The network system of the blockchain is essentially a P2P (point-to-point) network. Point-to-point means that there is no need for an intermediate link or centralized server to control the system. Everything in the network Resources and services are allocated to each node, and information can be transmitted directly between the two nodes. However, it should be noted that P2P
(peer-to-peer) was not invented by Satoshi Nakamoto. Blockchain just incorporates this technology.
So, the network layer of the blockchain is actually a particularly powerful peer-to-peer network system. In this system, each node can both produce and receive information, just like sending emails. You can write your own emails or receive emails sent to you by others.
On the blockchain network, nodes need to jointly maintain the blockchain system. Whenever a node creates a new block, it needs to notify other nodes in the form of broadcast, and other nodes receive After receiving the information, the block is verified, and then a new block is created based on the block. In this way, the entire network can jointly maintain and update the general ledger of the blockchain system.
However, what rules should the entire network follow to maintain and update the general ledger of the blockchain system? This involves the so-called "laws and regulations" (rules), which is what we will introduce next: the consensus layer.
3. Consensus Layer
In the world of blockchain, consensus, simply put, means that the entire network must maintain and update the general ledger of the blockchain system according to a unified and agreed-upon rule. Similar to the rules for updating data. Allowing highly dispersed nodes to efficiently reach consensus in a decentralized blockchain network is one of the core technologies of the blockchain and is also the governance mechanism of the blockchain community.
The current mainstream consensus mechanism algorithms include: Bitcoin's Proof of Work (POW), Ethereum's Proof of Stake
(POS), EOS's Delegated Proof of Stake (DPOS), etc.
We have now introduced the data layer, network layer, and consensus layer. These three layers ensure that there is data and network on the blockchain, and there are rules for updating data on the network. However, there is no free lunch in the world. How to make it happen? Nodes can actively participate in the maintenance of the blockchain system. This involves incentives, which is what we will introduce below: the incentive layer.
4. Incentive layer
The incentive layer is the so-called mining mechanism. The mining mechanism can actually be understood as an incentive mechanism: you are the blockHow much contribution you make to the chain system will determine how much reward you can get. Using this incentive mechanism, nodes across the entire network can be encouraged to participate in data recording and maintenance on the blockchain.
The mining mechanism and the consensus mechanism are actually the same. The consensus mechanism can be understood as the company's general rules and regulations, and the mining mechanism can be understood as, within this general rules and regulations, what you have done can What kind of reward you get, this kind of reward rules.
Just like Bitcoin’s consensus mechanism PoW, its stipulation is that the more work you do, the more you get. Whoever can find the correct hash value first can get a certain amount of Bitcoin rewards;
And Ethereum PoS stipulates that the longer who holds the currency, the greater the probability of receiving rewards.
It should be noted that the incentive layer is generally only available in public chains, because public chains must rely on nodes across the entire network to jointly maintain data, so there must be such an incentive mechanism to encourage nodes throughout the network to participate in the blockchain system. Construction and maintenance to ensure the security and reliability of the blockchain system.
The blockchain is safe and reliable, but it is not smart enough, right? The contract layer we will introduce below can make the blockchain system more intelligent.
5. Contract Layer
The contract layer mainly includes various scripts, codes, algorithm mechanisms and smart contracts, and is the basis for blockchain programmability. The "smart contract" we are talking about belongs to the contract layer.
If the Bitcoin system is not smart enough, then the "smart contracts" proposed by Ethereum can meet many application scenarios. The principle of the contract layer is mainly to embed code into the blockchain system and use this method to implement customizable smart contracts. In this way, on the blockchain system, once the terms of the smart contract are triggered, the system can automatically execute the order.
6. Application Layer
The last is the application layer. The application layer is very simple. As the name suggests, it is the various application scenarios and cases of blockchain. The "blockchain+" we are talking about now is the so-called application layer. The blockchain applications that have been implemented so far are mainly various blockchain applications built on public chains such as ETH and EOS. There are many gambling and game applications, and truly practical applications have not yet appeared.
