2. What is the domain of blockchain? Blockchain applications? The reason why we all say that blockchain is a subversive technology is that it is indeed the first time in the whole process of computer development that decentralized trust can be established from the technical level. Features: consensus, security and openness. First of all, blockchain is a multi-party consensus mechanism, and the consensus algorithm is the basis of building the whole technology trust. It does not rely on the trust of people and institutions, but a relatively democratic mechanism. Under the constraint of this mechanism, the authenticity, validity and persistence of data are guaranteed, so as to establish the trust foundation of this alliance business of multi-party Union and multi-party mutual supervision

secondly, blockchain is a relatively safe system. bitcoin is such a familiar blockchain application, and it is also the most successful blockchain application so far. So far, bitcoin has been running stably for 6-7 years. This system almost breaks everyone's idea of building a traditional financial system. First of all, it has no security facilities. Anyone who takes a machine into the network can join the network and work. In the whole bitcoin network, more than 80% of the machines are bare metal, They have neither good security protection nor any firewall measures; Secondly, because of the design of bitcoin, some of its data can track the history, prevent tampering and be irreversible

finally, it is an obvious feature of blockchain. It is a very open system. At present, there are many open source underlying implementations for your reference or use, and it is very scalable. It has been committed to establishing a multi center instry alliance or business alliance

Introction to Bubi blockchain

since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely

there are two extremes in the development trend of blockchain. Some people advocate private chain, while others advocate public chain. In fact, more than 90% of the mainstream applications in Europe and the United States are instry chain or alliance chain, that is, the upstream and downstream of an instry, or the semi open blockchain built by core enterprises, such as R3, LINQ of NASDAQ supported by chain, and some instry applications made by Dah to Australian stock exchange or Morgan

in fact, in the process of development and use of blockchain, it is around the following three important links: consensus, balance of book efficiency and scalability. Some geeks, such as bitcoin or Ethereum, are completely public. There are also some private chains used for efficiency transformation or connection between subsidiaries within enterprises. Most of them are upstream and downstream of instry alliances. They gather together for heating or jointly expand the business scale, which is the mainstream instry chain at present

blockchain naturally has two kinds of attributes: voucher and transaction. The attribute of voucher makes it the entrance of asset securitization and asset number, and the attribute of transaction enhances the free circulation of assets. Therefore, blockchain may become the infrastructure to build a free circulation network of value in the future

the field of blockchain? Blockchain applications? Referring to the development history of the Internet, the value free circulation network constructed by the blockchain is also an independent partial value circulation network (instry chain, alliance chain) formed by various instries according to their own needs in the early stage. In the later stage, driven by the demand for cross instry asset exchange, the instry chain is connected in series by some ways of interconnection, The formation of a de facto free circulation network of common value (public chain).

3. Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

4. At present, all countries are in the research stage of virtual currency. Blockchain is studied by large companies. Large companies have venture capital and will not go to ordinary people to invest. Therefore, the virtual currency and blockchain that ordinary people can invest in are fake.

5. Investment in blockchain can be viewed from the following perspectives:
first, what is the most important thing about the team? There is a saying in the investment and financing instry that investment is investment. This is the golden rule. Investment can be used for anything
the project is very important, but it is not the most important. If the people are right, everything is right. So the first thing is to look at the team. The most important thing in the team is the founder
has the founder ever been proved to be successful? Anyone in the grassroots team can pull it, but what have you done before? No matter how much luck he has, he has at least some characteristics of a successful person
it doesn't matter if you look at the right person, even if the investment project turns yellow, because an excellent entrepreneur will keep forging ahead, constantly find new things to play with, and his character is reliable
on the contrary, if this point is not judged accurately, no matter how strong the tuyere is, after all, not everyone can succeed in this tuyere, and even if you succeed, you may not get much profit, because it is very easy to kick you out
so for Xiaosan, the only purpose of judging the team is to believe that he can do it successfully. As for whether the market performance in the later stage is excellent or not, you can't see it just by looking at him and PPT. Unless he is a star with many successful cases in front, then when you invest, the investment value has reached the level compatible with the risk, so you can guarantee that he can do it
Second, look at the community
many people look at the project, who's the platform and whether there are big names. Is this important? It's a little useful, but it's not that useful
it's useful in the early stage, because there are few people watching their platform. Fans will think, "Wow, teacher so and so's platform, it must be a good thing that he really recognizes." Later, I learned that some of them were for the sake of friends' face, and some of them were for the sake of collecting money, so it's not very useful in the back of the platform
what is really important? It's the community! The number of people in the community, the degree of recognition of the community, that is, the stickiness of the community
when you buy a currency, you want it to go up. Why? There are enough buyers to go up. Who will buy it? The fans of big names will not come to buy it. The real reason to raise the price of a currency is from the real community users who really want to have this token to use in the ecology and who are proud of holding more tokens
they have piled up the market value of this community with real money and silver, and also realized group profit. The more people they buy, the more profitable they will be, and even direct financial freedom is possible. So you must see how the community construction of this currency is
therefore, the public chain technology of blockchain project is a threshold, but what is higher than the technical threshold is an excellent enough community
Third, project valuation
the first is benchmarking, which is vertical comparison. This proct is similar to what someone is going to do. Let's check the market value of this proct and how much it is. It's a benchmark to see how many times there is room for growth
the second one is horizontal comparison. You can switch it between bull and bear to see where its valuation ranks and whether it is undervalued< Fourth, whether it is necessary to judge whether a blockchain project has prospects depends on whether the project must be transformed by blockchain
in most cases, we should choose those projects that have real innovation and solve practical problems, but this problem has not been completely solved, and its token has irreplaceable application value in the ecology, not just those projects that replace legal currency and bitcoin
the above four conditions are met: reliable team, enough community members, strong stickiness, low project valuation, large appreciation space, and huge irreplaceable ecological value. Not to mention all in, there is no big problem in long-term holding.

6. Recently, under the banner of "financial innovation" and "blockchain", some lawless elements in Hainan have absorbed funds by issuing so-called "virtual currency", "virtual assets" and "digital assets", thus infringing the legitimate rights and interests of the public. This kind of activity is not really based on blockchain technology, but hypes the concept of blockchain, illegal fund-raising, pyramid selling and fraud, which mainly has the following characteristics:
1. Obvious networking and cross-border. Relying on the Internet and chat tools for transactions, and using online payment tools to balance funds, the risks spread widely and spread quickly
Second, deception, temptation and concealment are strong. They use hot concepts to hype, fabricate various "tall and tall" theories, and some also use celebrity "big V" platforms to publicize. They use airdrop "candy" as temptation to claim that "currency value only rises but not falls", "investment cycle is short, income is high, and risk is low", which has strong bewitching. In practice, criminals illegally make huge profits by manipulating the price trend of the so-called virtual currency, setting profit and withdrawal threshold. In addition, some criminals also issue tokens under the guise of ICO, IFO, IEO, etc., or hype virtual currency in the way of IMO under the banner of sharing economy, which has strong concealment and confusion
thirdly, there are many kinds of illegal risks. Through public publicity, criminals use "static income" (currency appreciation profit) and "dynamic income" (development offline profit) as t to attract public investment, lure investors and development personnel to join, and constantly expand the fund pool, which is characterized by illegal fund-raising, pyramid selling, fraud and other illegal behaviors
this kind of activity takes "financial innovation" as a gimmick, and its essence is a Ponzi scheme of "borrowing the new to repay the old", so it is difficult to maintain the capital operation for a long time. The general public should treat the blockchain rationally, not blindly believe the promises, establish a correct monetary concept and investment concept, and effectively improve the risk awareness;

7.

Blockchain is a new application mode of distributed data storage, which is an important concept of bitcoin. At present, there are 35 stocks associated with the blockchain concept in the A-share market, of which 6 blockchain concept listed companies are traded on the Shanghai Stock Exchange, and 29 blockchain concept listed companies are traded on the Shenzhen Stock Exchange

according to the correlation of blockchain, the leading stocks of blockchain concept stocks are most likely to be born from Xinchen technology, luyitong and Sifang Jingchuang

Xinchen Technology: on September 29, 2016, the company said in the interaction that the company is now doing research and development of blockchain technology

Lu Yitong: the company plans to raise 67.9691 million shares of additional shares of RMB 24.57 per share, and the total amount of supporting funds will not exceed RMB 1.670 billion, which will be used to pay the cash consideration of this transaction, construct the block chain ASIC chip instrialization project, artificial intelligence ASIC chip R & D center, chip proct marketing and service network, etc

Sifang Jingchuang: on May 31, 2016, the inaugural meeting and the first general meeting of the financial blockchain cooperation alliance (Shenzhen) was officially held in Shenzhen Wuzhou Hotel, and the company was one of the members of the meeting

8. Yingchi Hall of fame is the top non-public graphics card. Although the time of silent frequency is similar to 1060, the ability of overclocking is much stronger than 1060. The official power consumption is 165W, while 1060 is 120W. After overclocking, the power consumption will be higher. Pay attention to whether the power supply is enough. The price of 900 yuan can be bought, but please note that if you play a stand-alone game, it may explode in some games. As for mining, so to speak, there is no ore card in the 9 series, and the N card mining was started on a large scale in the 10 series. It may have been before, but it's too few. Before the 10 series, they used to dig with a-card.

9. TTC is the abbreviation of time
treaty
chain in English. There is a branch in Shenzhen called time treaty blockchain Technology (Shenzhen) Co., Ltd. Time
treaty
chain (TTC), for short, is committed to building a decentralized, open-source, compound contract function chain ball ecological platform with block identity technology as the core. The initiative of block identity aims to realize the global block identity traffic ecology of (public chain +
alliance chain + private chain) * side chain in the digital world.
