3. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
blockchain is public on the network and can be queried in every offline bitcoin wallet data. The function of bitcoin wallet depends on the confirmation with the blockchain. An effective inspection is called a confirmation. Usually, a transaction needs to obtain several confirmations. The lightweight bitcoin wallet uses online confirmation, that is, it will not download the blockchain data to the device storage
many of bitcoin's competitors also use the same design, but the workload proof and algorithm are slightly different. For example, the use of proof of interest and scrypt and so on<

the concept of blockchain time stamp certificate service and proof of existence was proposed in the white paper [1] of Nakamoto Tsung, which created the first block, namely "Genesis block"< On January 3, 2009, the founder of bitcoin, Mr. Nakamoto, left an unchangeable sentence in the genesis block:
"the times 03 / Jan / 2009 Chancellor on brink of second low for banks (on January 3, 2009, the chancellor of the exchequer was on the verge of implementing the second round of bank emergency assistance)."
at that time, the British Chancellor of the exchequer, darling, was forced to consider a second attempt to relieve the banking crisis, which was the headline of the front page article of the times that day
the time stamp service and existence proof of blockchain, the time generated by the first blockchain and the events that happened at that time are permanently preserved
BTCC, a bitcoin company, launched a service "Millennium chain" in 2015, namely blockchain lettering service, which is based on the above principles. Users can use this service to engrave text on the blockchain and save it permanently
bitcoin, Laite coin, Ruitai coin and Qianjin card are all digital currencies based on blockchain technology.

5. Today's Internet, has almost perfectly solved the problem of information transmission, anyone, at any time, anywhere can carry out simple and fast information transmission at low cost; However, the transmission of value still depends on the central organization accounting, and the end-to-end direct transmission of value is still not realized. Blockchain technology, as a trust building machine, establishes trust through algorithms, and accounts by the network rather than the central organization, realizing the end-to-end transfer of value. In short, blockchain is a distributed shared accounting technology. It is a database that can not tamper with the time ordered cryptography account book, which is jointly maintained by multiple nodes and guaranteed by a unified consensus mechanism. As the first technology that can establish decentralized trust from the technical level, blockchain has subversive significance. On the blockchain, anyone who doesn't know each other can complete end-to-end bookkeeping, data transmission, authentication or contract execution by virtue of the open and transparent trust relationship of database endorsement, without reaching a credit consensus through an intermediary in advance< br />?
Bubi (Beijing) Network Technology Co., Ltd. (hereinafter referred to as Bubi) is a leading blockchain technology service provider in China. Since its establishment, Bubi has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technological achievements, For example: mathematically proven distributed consensus technology, fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. We have developed our own blockchain basic 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
on April 25, China's first asset based blockchain integration platform, gege integration, jointly built by Bubi company and Guangdong gege Integration Application System Co., Ltd., was ceremoniously launched“ "Gege integral" introces the integral system into the concept of blockchain. It is jointly opened by multiple parties, and points are issued and exchanged to promote the circulation of points. 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
traditional points are debt based points, which are characterized by scattered points, weak consumption, more restrictions on use, cumbersome exchange and difficult circulation. If a merchant "issues" the integral, B merchant does not give cash; At the same time, the points can not be transferred or given away, which leads to the limited brand communication of the points issuers. In addition, the use of traditional points often has a certain period of time, which will be automatically cleared after expiration. The grid points with blockchain as the bottom layer have the following characteristics: the number of points issued by each merchant can not be forged, tampered or deleted; Lattice integral has a unique number, and the circulation of all integral can be traced; The integral data is stored in the whole network, even if 99% of the network fails, the integral information will not be lost. The validity period of grid points is permanent by default, and users can hold and use it with confidence. This kind of integral has the characteristics of free circulation, mutual gift, convenient exchange, breaking into a whole, comfortable communication, etc. for users, it is more disposable and more valuable. For merchants, the active points promote brand communication, increase the stickiness of consumers and merchants, and also benefit merchants to share and complement customer data
at the press conference, a number of contractors issued bonus points. The guests experienced the whole process of points collection, gift and exchange. Nearly a thousand participants also experienced points collection, account creation and points transfer. This unprecedented barrier free exchange of points made the interactive atmosphere of the conference high
Huang Xiaogang, chairman of Guangdong gege integral operation system Co., Ltd., said that the gege integral platform will be a super large integral platform. With the rapid growth of users, the number of businesses entering will increase and the brand effect will become greater and greater. As an open business integral platform, it will bring a revolutionary reform to China's integral system. Bubi firmly believes that there will be more and more store points merchants accessing the platform to jointly build a trusted digital asset platform and realize the free distribution and circulation of points. Then, Bubi team will also give more support in the field of blockchain technology. The Internet in the future must be an infrastructure that can provide reliable and free flow of value

Jiang Hai, founder of Bubi blockchain: let digital assets flow

Dr. Jiang Hai has a deep accumulation in blockchain technology, distributed computer network and network information security. Bubi company, founded by him, focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to let digital assets flow freely

Yu Tingting: please introce Dr. Bu Jiang to us what Bubi does<

Jiang Hai: what Bubi needs to do is a new technology and proct to realize the real value circulation and make the Internet reach a new height. With the application of this technology, when transferring assets, there will be no central organization, which can realize the direct transfer of assets between us. In the future, if the network itself can settle the bill, we can transfer it directly, and we don't need to go through an intermediary< Guo Feng: with the development of Internet in China for more than 20 years, the zero cost transmission of point-to-point information has been solved, but the transmission of value and credit is difficult to achieve. Is there a way to solve this problem? Fortunately, there are! That's what Bubby is doing<

Yu Tingting: it sounds like a world shaking thing to me. Even you will eliminate many instries and remove the intermediary of many instries<

Jiang Hai: at present, all the major banks, investment banks and exchanges are carrying out initial research and experiments in this field

"blockchain" is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry

Jiang Hai: because today's blockchain technology, which has attracted worldwide attention, is completely different from the original bitcoin blockchain technology

Yu Tingting: so you (Guo Feng) are investing in the brains of these scientists< Guo Feng: traditional technology plus blockchain can make the technology to a new level. In fact, what they are doing now is blockchain +

Yu Tingting: now, from the perspective of an investor, is there any risk<

Guo Feng: if the real disruptive innovation is too tangled with its business model at the beginning, it will not be invested. The greater the differentiation, the greater the prospect of the business model. This is my understanding. However, there is no company in China to do the underlying technology, so we did not hesitate to invest in such a team<

Jiang Hai: I hope our common cause will blossom and bear fruit in 2016 and after 2017, and we can go to the international forefront in the blockchain instry

Yu Tingting: I hope I have the honor to witness it.

blockchain? Maybe few people can really answer this question. It is precisely because of the inherent mystery of "blockchain", that many people are eager to pay for knowledge in order to get on the train to the "future"

therefore, all kinds of blockchain training are also very popular, and all kinds of information, such as "scanning code, entering the group to listen to lectures", are filled with the circle of friends, so it is difficult to distinguish the good from the bad. The training costs are even more uneven: 100 yuan, 300 yuan, 7000 yuan or even nearly 100000 yuan...

blockchain training is too hot

I often make up my identity on the dating materials, such as import lighting wholesalers, urban landscape designers, boutique tobacco hotel owners and agricultural loan salesmen. Now, I have finally become an expert in blockchain training courses

and it is reported that a blockchain recruitment advertisement in Beijing recently blew up the circle of friends, requiring candidates to have in-depth research on blockchain technology and cryptography, giving an annual salary of not less than 5 million yuan, and not capped

"this is really the current situation of blockchain talent recruitment. But even so, we can't find people, because it's hard to find qualified people. " Lu Sheng, head hunter of Liepin platform, said

Song Mofei, senior researcher of Suning Institute of finance, said: "in terms of development experience, the rise of domestic blockchain instry has been concentrated in the last two or three years, and few people have long-term blockchain development experience in the talent market." He believes that excessive salary will inevitably attract some speculators, but the increase of salary does not bring about the increase of the application threshold, and even some recruiters only know a little about blockchain technology, which also poses new challenges for the recruitment of blockchain talents

according to Shan Yi, chief data officer of liepin.com, the core of blockchain is the change of social relations and business model based on Internet distributed trust system, which is characterized by decentralization“ There are still many uncertainties in the future development of block chain. There are obvious bubbles at present, and many block chain projects are not reliable. He said

8. In mid March, the central bank issued a notice on further strengthening bitcoin risk prevention (hereinafter referred to as the notice) to all branches of the central bank, which required banks and third-party payment institutions to close all trading accounts of more than 10 domestic bitcoin platforms. This means that it is illegal for financial institutions to open trading accounts for bitcoin website platform. Except for cash transactions, bitcoin investors can not conct bank transfer and third-party payment for transactions in China, which is unprecedented
the notice requires commercial banks and third-party payment institutions to close all accounts of these platforms, and the deadline is April 15. Before this deadline, these accounts can still be withdrawn, but not recharged. If it fails to close within the time limit, the central bank will punish it. In addition, the central bank also requires the payment and clearing association to continue to track the changes in the recharge means of the platform and report to commercial banks in a timely manner.
