Blockchain innovation picture
what is centralization
the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent
the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers
the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high
at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know
so, in which fields can blockchain be applied, what kind of changes will it bring to our future life
the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud
core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people
Application:
1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment
2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute
3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city
4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords
in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.
e to the decentralized accounting method, open and traceable data, intelligent contract to ensure trusted transactions and other characteristics of the technology itself, blockchain is a perfect match for various applications in finance, logistics and other fields. However, e to the market's low acceptance of blockchain technology and the incomplete development and basic conditions of related instries, the technology has not been widely used in related instries. However, some instries with concentrated indivial users are ahead. The game instry has a huge demand for users to buy and sell game equipment, and the game equipment belongs to digital assets, Transaction has financial attributes, and it is also an ideal scenario for the application of blockchain technology< br />
looking at the current domestic blockchain games, dozens of them have appeared in recent half a year, but most of them are pet nurturing games with pictures and words to explain the rules, which have little entertainment value. Some Internet reports also mentioned that it only takes about five days to a blockchain pet game. It can be imagined that the blockchain game copied by such a simple method is difficult to be well designed and even less attractive to players. There are also other types of blockchain games, such as real estate games. Users can use tokens in game scenes to purchase land, services and procts in the virtual world, obtain property rights, and build buildings on their own land. But this kind of game in the country to do more influential is rare< br />
the combination of blockchain and games is supposed to improve the convenience and effectiveness of game digital asset management with blockchain technology, so as to enhance the overall use experience of players. However, the current domestic mainstream practice is to find suitable landing applications for blockchain technology, and reluctantly implant blockchain technology with simple and crude games, This practice of "block chain for the sake of blockchain" undoubtedly deviates from the design intention of the game itself from the source, which is the pain point of the domestic blockchain game instry< br />
in fact, many popular games on the market do not have very complex design ideas, as long as the extremely simple operation can help white-collar workers relieve the pressure of intense work. Simple but not hasty. Users play simple games, designers often spend more time in the game development stage. For example, an Auckland miner game, which is popular in New Zealand recently, uses the mutual help between human beings and elves in the magic world to connect simple story clues, and takes the beautiful natural scenery of Auckland island under different geographical environments, such as forests, caves and glaciers, as the basis of game art design. Although the play method is simple, the picture is beautiful. Players can "hire" miners to dig gold coins with the game token. Of course, the gold mining capacity will vary with the miner's level, and different mining tools will also affect the gold mining effect. The game also has a "steal" gold coin mechanism, that is, players can invite friends to participate in the game, and in the case of friends "not in the mine", they can take the opportunity to steal the other party's gold coins, so as to quickly increase their wealth. Of course, "steal" also have a way, as long as the player requisition "guard dog" guard "mine", can avoid the loss of theft. This part of the game is very similar to the popular "stealing vegetables" game in recent years. Although it is not innovative, it caters to the interactive nature of social media, which is one of the reasons why the game can rapidly expand the overseas Chinese circle. For game users, this kind of game does not need to be thought-provoking, and they do not need to concentrate on it. Players can "steal" people's gold coins while chatting with others. I believe this kind of "secret joy" is also a small sense of achievement for many players to play this game< br />
of course, as a blockchain game, Auckland miners also provide game profit channels for players, that is, while playing the game, players can earn tokens by mining, and get appropriate returns while paying the time cost. This is also one of the important reasons why many blockchain games can attract a large number of fans< br />
the success factors of Auckland miner game are briefly analyzed, including simple game logic, interactive social attribute, token profit mechanism, and finally the art design of the game itself. The original intention of players to participate in the game is to get entertainment and relaxation from the game. Therefore, pleasing art design and game interface are also the key to the success of any game. At this point, Auckland miners game takes the beautiful natural environment of New Zealand as the background of the story, and has natural advantages, which will also help this game to become popular quickly.
In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contracts composed of automated script code to program and operate data
working principle
blockchain system is composed 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 algorithms such as data encryption and timestamp; The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of 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 all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain; The application layer encapsulates various application scenarios and cases of blockchain. In this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology
In the era of mobile Internet, the dividend is over, and the next stop is blockchain. On June 4, Xiao Wei, a network blockchain scientist, presented the new generation blockchain network operating system "super chain" of the network for the first time at the opening ceremony of the 2018 chain Valley lecture hall
the blockchain field ushered in a major event, that is, the network publishing super chain. Over the past few years, many enterprises have entered the field of blockchain. This network release of super chain is a solution to promote the development of blockchain, which is of great positive significance. This solution is also regarded as the network embracing the blockchain. What's more, the future is generally optimistic
the network once missed the opportunity of mobile Internet. The most obvious example is the tragic failure in the field of o2o. The network glutinous rice, which used to bet heavily, is now facing the situation of being trapped by hungry and meituan comments. The hopeless network will focus on artificial intelligence, hoping to pull back in the era of artificial intelligence
as everyone knows, in addition to artificial intelligence, there is also a revolutionary technology that is setting off a global upsurge, which is blockchain. And the network, never want to miss the chance to change their destiny again
Blockchain instry development trend analysis technology has broad application prospects
with the characteristics of point-to-point payment, openness and transparency, the most direct application field of blockchain technology application is payment field. However, there are many pain points in domestic ticketing instry, such as too many agent levels, rampant scalpers, selling more than one ticket, fake tickets, lack of credit, etc, It can be solved by blockchain technology. The traditional ticketing mode needs the support of centralized facilities such as the third-party ticketing platform, and the information is extremely asymmetric. The new ticketing mode based on blockchain technology can realize point-to-point transaction, and the whole process is transparent and traceable
blockchain e-ticketing platform

data source: the financial field of blockchain + application sorted out by prospective instry research institute is reshaping the financial instry pattern
the open and tamperable attribute of blockchain technology provides the possibility for decentralized trust mechanism,
has the potential to change the financial infrastructure. All kinds of financial assets, such as equity, bonds, bills, warehouse receipts, fund shares, etc., can be integrated into the blockchain ledger to become digital assets on the blockchain. They can be stored, transferred and traded on the blockchain, which makes them have a very broad application prospect in the financial field
by recing the cost of cross-border payment, securities trading and compliance, blockchain technology can save banks $15 billion to $20 billion a year
through the application of intelligent contract, blockchain + insurance can realize automatic claim settlement of insurance policy. Insurance institutions have high management and operation costs, and the data on the blockchain is true and reliable, which can effectively simplify the processing process of policy claims. In addition, the blockchain technology can realize the digital management of personal data, simplify information authentication, and help to trace the history of data
entertainment of blockchain + application: the development ecology of blockchain has taken shape, and the media instry may become the main beneficiary
blockchain technology can be widely used in news, games, picture right and other entertainment fields
blockchain technology will bring great changes to the underlying structure of the game and have a great impact on the current game instry. Gamers now have gatekeepers (centralized organizations) to decide prices, tax, censor users, control content, and profit from data. Through the decentralized platform, consumers can socialize and trade without mediation, providing more control and flexibility for game players in the game experience
blockchain + applied supply chain: it can improve the transparency of the supply chain, establish a new supply chain system
blockchain technology can improve the transparency, traceability and security of the supply chain, and promote a kind of trust and integrity. 1) At present, the supply chain has many disadvantages, such as long chain, many intermediate links, many interest joints, opaque and so on; 2)
the distributed bookkeeping technology of blockchain can register the transfer of goods on the ledger as a transaction, and determine the participants related to the proction chain management, as well as the proct price, date and location
