Libp2p blockchain
in China, the representative of the combination of blockchain and real estate is the blockchain real estate application "fangyixin" of Xinyuan group, a listed real estate company. Public information shows that Xinyuan is IBM's first partner in the field of blockchain in China
on the platform, IBM provides the underlying blockchain technology and intelligent contract technology. On this basis, Xinyuan builds the upper real estate information database, real estate valuation system, transaction circulation system, risk control and other moles, which are said to support a variety of financial applications such as consumer finance, investment and financing finance, instrial finance, etc., and connect with investment and financing institutions, credit reference institutions and consumer businesses
however, the combination of blockchain and real estate instry is still in its infancy in terms of application. It will take time to test which step it can take and whether it will attract the attention of the national team like digital currency
blockchain not only has an impact on the real estate instry, but also has a potential impact on the existing instries. Coin Ying China and China post are in the forefront of using blockchain technology. Coin Ying China uses blockchain to reshape the crowdfunding instry, while China Post takes the lead in applying blockchain technology to asset custody.
Financial instry
blockchain should be the most widely used in the financial instry
, for example, OMG (young model currency) in May 2017, omise announced that it was launching an electronic wallet with Alipay to integrate Alipay payment solutions into its own payment service suite, helping local e-commerce businesses in Thailand to accept online payment transactions from China tourists. p>
another example is PPT, which is a bill financial transaction system based on blockchain
gambling
the gambling instry probably entered the blockchain last year. Why does gambling favor blockchain? Blockchain provides a relatively fair guessing system. Why is it relatively fair? As can be seen from the previous introction, blockchain can not be tampered with or forged
for example, wicc is a rich application scenario that can realize asset issuance, guessing application, right traceability, mutual insurance, decentralized exchange, cross-border settlement, etc
for example, the STX stox application is designed to provide the full functionality of the forecast market application without any central server. Forecasting the market requires functions such as event planning, market making, providing information and analysis to traders, reporting event results, and of course collecting and paying
I believe that if the current lottery instry is set up on the blockchain, people's purchasing enthusiasm will be higher and higher, because too many insiders make people give up
Internet of things
there are still many applications of the Internet of things in the blockchain, because the traceability and timeliness of blocks are very suitable for this instry
for example, data is the concept of Internet of things, which is a decentralized P2P network. The data source can connect with any node in the whole network, and then publish the data, and the network will immediately send it to the subscriber. Horizontal scalability is achieved through fragmentation mode. This is very important for the timeliness and accuracy of Internet of things applications
game instry
for example, GTC (g coin) is a decentralized digital asset based on Ethereum erc20 issued by game.com, and G coin is committed to becoming the general digital currency standard of the global game instry
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 the ownership of virtual territory through the land ledger based on blockchain. The territory is demarcated by rectangular coordinates (x, y), and its owner can decide the content published on the territory, including interactive systems from static 3D scenes to games
there are many other instries. The great emperor did not list them one by one, but listed several representative instries. What is the point? It shows that blockchain is definitely not only the transaction of currency, it is a proct of the era change with real landing project and real practical use
in fact, the development of human society is just like the blockchain, which is irreversible and unstoppable. In my opinion, sooner or later, the blockchain will enter into thousands of households, no matter the ox or bear, hold the value currency in hand, and tonghuashun has begun to offer digital currency, which shows that the society is accepting it step by step, and the power of social development can not be blocked by any country or person
as part of the blockchain, the regulatory authorities (central bank, China Banking Regulatory Commission and China Securities Regulatory Commission) can obtain the public account books of P2P transactions in real time, and obtain the financial management projects and capital transfer information of each P2P enterprise by analyzing the public account books, so as to provide low-cost, efficient and reliable regulatory data for the supervision of P2P instry in real time Second, the borrower's credit transparent blockchain is mainly to solve the credit problem, so the blockchain is the most promising application in credit investigation. However, there are many controversies about credit information. After all, the data related to credit information is very sensitive. Both credit information institutions and users do not want to make it public. Data is the lifeblood of credit information institutions. Every family wants others to make it public and keep it secret. Users also don't want their data to be public. Of course, if we can achieve the transparency of credit investigation in the future, it will be very beneficial for P2P investors Third, the transaction structure of low-cost for a P2P platform, the monthly withdrawal fee of users is not a small expense, but the general P2P platform will pay this part of the fee out of their own pocket. It is a good thing for the P2P platform to apply the powerful online transaction function of blockchain, go to the third party payment, or bank fund custody, and complete the fast, prepared and transparent transaction of funds
The current blockchain procts can be defined as Ponzi scheme except bitcoin. The concept of blockchain was born in 2008, but it was after the growing market value of bitcoin that it was recognized by the public and became popular in China. Bitcoin gained its market value only eight years ago after a foreign programmer spent 10000 bitcoins to buy two pizzas. After eight years of long value-added period, the 10000 bitcoins, which once had a market value of only $40, now have a peak value of nearly $200 million
technology is a liar without capital, and the platform built by blockchain without transaction record is a great liar
blockchain builds a fair trust platform with the method of [all bookkeeping] (generally speaking, I called XXX to borrow my 100, and everyone wrote it down, so the transaction can be completed without middleman, and the completion process depends on the records of the whole platform), but the transaction currency does not generate value out of thin air, but accumulates its value little by little in each transaction, In the end, it became money. The endorsement of its value is caused by countless transactions
then other blockchains have three major problems: 1. The maturity of Technology (there is no recognized algorithm now) 2. How can you guarantee the appreciation of these currencies? 3. How to ensure that others don't yell for transactions? The method of blockchain is to increase the difficulty of yelling out (for example, if no one gives me money, I also yell for money, and you can write it down in a small notebook). The method of blockchain is to remember that a small notebook needs to be upside down and write with a pen in its mouth...), so the problem of mining out of thin air may be caused by the technologist
therefore, blockchain is basically a Ponzi scheme except for accumulating a lot of bitcoin in the transaction process. What you're involved in is that the platform will use their virtual currency to trade a lot in the future , whether the monetary value of blockchain output is high or not is e to its trading volume as an intermediate currency, is no different from stock speculation - but stock speculation is actually a Ponzi scheme
the funniest thing is, Blockchain has been calling for decentralization, but if you want to make money to make the circle, the more you have to rely on the endorsement of the big platform to ensure the circulation of money, the more you want to be decentralized, the more you need to help the central GZ government legislate - the funniest thing in life is this, just like VR was riding on pockmango, an AR proct in the first year
the integration of P2P instry and "blockchain" can not only make use of the unique advantages of "blockchain", but also make the whole instry more "transparent", injecting fresh blood into the whole instry. At the same time, as time goes on, blockchain technology may exist in a large ecosystem with both centralized and decentralized modes. In the future world, there may be considerable complementary space for both centralized and decentralized models
however, at present, most of them just stay in the theoretical stage, and the actual application scenarios do not appear. However, the combination of digital currency and tea is indeed a relatively novel project. Puyin group launched the tea based digital currency Puyin.
the main functions of the P2P system developed by using blockchain technology are to help supervise P2P enterprises, transparency of borrowers' credit reference, low cost of transaction structure, and instry infrastructure (blockchain technology can be used as a very important new infrastructure construction for P2P and even the whole Internet financial system). At present, the enterprises that use blockchain technology for P2P system development, such as Yingtang Zhongchuang, are important development enterprises of blockchain technology in transaction system and practical application.
US media disclosed on the evening of 17 local time that Cambridge analysis, a British company deeply involved in the scandal of abusing personal privacy data, originally planned to launch a personal privacy data storage service and sell it in the form of encrypted currency through blockchain technology. The concept of personal information encryption and monetization is not new. The key to this idea is everyone's autonomy of personal information. Some people in the instry believe that blockchain technology may bring a "revolution" in personal data protection
in the era of big data, personal data is considered as precious as gold. Personal data leakage is worrying, but the vast majority of people can't be cut off from the Internet because of the fear of data collection. At present, enterprises, schools, hotels, social networking sites, etc., which are responsible for keeping personal information, often fail to take the responsibility. Experts believe that blockchain technology, as a "middleware" with encryption, trust, point-to-point, and difficult to tamper, is expected to solve this problem
the emergence of blockchain technology makes it possible for everyone to control their own personal data by transferring the control of personal data from Internet companies to users themselves. Through it, users' personal data can be associated with their personal digital ID card. Users can choose whether their digital ID card is anonymous, pseudonym or public. They can also access the blockchain application platform from any device anytime and anywhere to control their Internet personal data
for example, the information on the block chain of someone's ID number may be converted to a series of ciphertext, and the face image information is also encrypted. When he checked in at the hotel, he only sent the cipher ID number to the hotel through application. The hotel compares the information with the encrypted data on the block chain application, and does not need to know any real information of him, but as long as the encrypted data match the result, it can guarantee the check in.
at the same time, the development of big data and artificial intelligence needs a lot of user data resources. Users can selectively sell their personal data as cryptocurrency and receive certain returns. For example, if e-commerce needs user data to develop a new application, users can choose to sell their own shopping history data, but their address, account number and other information can still be kept confidential
in the field of gene sequencing, blockchain applications have begun to challenge the "way to make money" of traditional gene sequencing companies selling personal data
in recent years, gene sequencing services for ordinary people have been popular. Take "23 and me" chromosome biotechnology company in the United States as an example. Consumers only need less than $100 and a few mouthfuls of saliva to get family genetic information. If they pay another $80, they can get in-depth analysis of genetic health risks and other aspects based on the original data. However, the company was not satisfied with the revenue from sequencing services. It also sold millions of customer genetic data to pharmaceutical companies by classification and packaging. The Parkinson's disease data sold in early 2015 alone amounted to $60 million. Many similar biotech companies, while obtaining service income from consumers, resell the data of consumers to "earn double money"
in February this year, George church, a geneticist at Harvard University in the United States, founded "nebula gene", hoping to break this pattern through blockchain technology. The company plans to complete the whole genome sequencing at a price of less than US $1000. The cost is borne by the customers. In return, the customers can intuitively understand their own genetic information and corresponding disease risks, and also have the autonomy of sequencing data. The security of genetic information will be guaranteed by blockchain technology. At the same time, it will be encrypted and monetized, and it will be stored and sold according to customers' wishes
the company plans to launch a kind of "Xingyun coin" as the trading medium. Customers can exchange their genetic information into "Xingyun coin", and they can also use "Xingyun coin" to pay for their own sequencing expenses. Pharmaceutical companies can purchase "Xingyun coin" with traditional currency to obtain the genetic information data of ordinary people. The whole trading process is completed through the blockchain platform, Encryption is transparent and secure
chech said that after integrating the cost of sequencing, genetic information protection, data management, genome big data processing and other factors, blockchain technology allows more people to truly "own" their own genetic information.
