1. bitcoin and blockchain international summit aims to popularize the knowledge of bitcoin to more people while promoting the technical exchanges between domestic and foreign cryptocurrency instry and blockchain. The "China's first bitcoin documentary" brought by the summit is the best proof. I hope more people can learn about bitcoin and blockchain through this documentary, and explore the future together.
2. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. As an important concept of bitcoin, blockchain is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, which is used to verify the validity of the information and generate the next block
this is a passage in Alibaba's documentary dreamer. When ps: is repeated many times, it can explain the term "third parties" very well. This is also the beginning of Taobao and Alipay's birth. In other words, at that time, Ali was forced to act as a "third party" because no company could play such a role, so Ali became a center of trust. Businesses and users chose to give money to Ali because of "trust". But what if Ali absconds with money (though impossible...) or if the financial operator has problems (after all, it's human...)? If only there was a machine or a "super system" to do these things! Today, more than ten years after the replacement of Internet technology, blockchain appears in front of us, right! It's the super system;! A machine of trust
with blockchain, things start to change
traditional centralized mode:
decentralized mode under blockchain network:
in decentralized network, each user can be directly contacted without any third party's participation, and the transfer between users is like hand-in-hand cash, which is why bitcoin is called "e-cash"
well, now that a has transferred the money to B, who will charge the account? Alipay has helped me keep account of accounts, which will be unified in Alipay backstage system. In order to make all the transactions of the users recorded and the accounts are correct, Alipay will make great efforts to this end. Look at Alipay's initial
1000 bills per day. Artificial reconciliation is already very painful. With the volume of Alipay now, there are less than hundreds of thousands of bills per day, even if the system reconciliation is unavoidable, and it is necessary to pay the corresponding manpower and material resources to maintain this very complex revenue and expenditure clearing system. Having said so much, how does the blockchain reconcile? The answer is: no! There is no need for reconciliation and zero clearing in the blockchain network, because every node in the blockchain (a computer or a user) has its own account book, which is updated in real time. Any transaction in the blockchain network will be recorded in your own account book. Yes, you also have other people's accounts, But you don't know who this person is, because they all look like this:

3. I transfer bitcoin to you. Do I still have bitcoin in my hand
the fourth feature of blockchain assets is that they cannot be copied. The transmission of information on the Internet is . I sent a very interesting picture to fire coin Niuniu. The network copied the picture in my hand to Niuniu. It wasn't really taken away from me. I still have this picture in my mobile phone
right on the Internet has always been a big problem. Words, pictures and images are easy to , which brings great trouble to their right owners
the reason why blockchain assets can become assets is that they cannot be copied. It can be delivered through encryption rather than ing. When I send a block chain asset worth 1000 yuan to Niuniu, the 1000 yuan asset will be transferred from my account to Niuniu's account, and I no longer own the 1000 yuan asset. Non replicability is an important factor to ensure that it becomes an asset.

4. (1) Firstly, okgroup was established to focus on the research and development and promotion of the underlying technology of blockchain. The blockchain public chain developed under the leadership of Xu Mingxing has greatly improved the scalability of public chain technology, and has reached the world's leading level in many aspects, such as innovative state fragmentation mechanism. He has provided cutting-edge technology for the development of blockchain in China, become the catalyst of China's blockchain, and promote the rapid development of China's blockchain technology
(2) under the leadership of Xu Mingxing, okgroup has created and published authoritative books such as "illustrated blockchain" and "general economics", and proced visual popular science procts such as "chain and the future" series animation short films, and "blockchain · record", a public welfare documentary of the instry. Through these procts, it can disseminate instry information such as frontier trends, technological achievements, and technological applications of blockchain, And export valuable blockchain business knowledge to the business community through the business school
(3) okgroup, founded by him, is one of the earliest blockchain enterprises in China and a leader in the blockchain instry.

5. Blockchain, a great technology with the birth of bitcoin, can greatly rece transaction costs and improve efficiency in the financial field, which is enough to make Wall Street excited. However, this is only the tip of the iceberg, and its potential application prospects are very wide, which will subvert all aspects of our lives in the future
to put it simply, blockchain is similar to an account book, recording all the transaction information of bitcoin. This ledger is stored on each bitcoin node of the Internet, and each node has a complete backup. The ledger is stored in blocks, and each block contains some transaction records. Each block will record the ID of the previous block, forming a chain structure, which is called blockchain. When you want to initiate a bitcoin transaction, just broadcast the transaction information to the P2P network, record your transaction information as a new block and connect it to the blockchain, and the transaction is completed
to sum up, the biggest feature of blockchain is decentralization. There is no centralized hardware or management organization in the whole network. The rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system
the second feature is distrust. There is no need to trust each other in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are open. Therefore, within the specified rule range and time range of the system, nodes can not and cannot cheat other nodes
the third feature is to break the information asymmetry. Blockchain's ledger technology will reflect all the information, similar to an open and transparent credit system of the whole society, breaking any asymmetric information in all societies
these three features alone are enough to make blockchain overturn our present life. The financial instry is one of them
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
for example, our common inter-bank clearing systems, securities settlement institutions and various financial settlement systems are based on this principle, but the difference is that these settlement systems are centralized, that is, there is a central server or central institution to complete the settlement work. If the central institution database is damaged, the whole settlement will go wrong. The settlement system of bitcoin is decentralized and built on the network. We call it P2P network. It is a decentralized settlement database. The destruction of indivial database nodes does not affect the whole bitcoin settlement network at all. Therefore, the distributed data settlement network based on P2P network is a new financial innovation
blockchain technology concept stock? Blockchain is 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. According to the forecast, by 2025, 10% of the relevant information in the global GDP will be saved by blockchain technology. Blockchain technology is facing a blue ocean, and related concept stocks are becoming the wind. In A-share listed companies, it is suggested to focus on the concept leading stocks: Feitian integrity, Yuyin shares. In the future, with the fermentation of speculation, other concept stocks are expected to follow suit
blockchain stock? Blockchain technology concept stock? The part of stock trading is very simple, but the process of clearing and settlement becomes complicated. Blockchain trading can greatly simplify this part of trading
the convenience brought by blockchain is reflected in the stock cash transaction, which mainly reces the time of clearing and settlement process. Specifically, it means to rece or eliminate the wrong transactions, improve the efficiency of the back office, and rece the settlement time.

7. In the field of capital, the water is very deep. It is an era in which opportunities and challenges coexist and pitfalls and pie are deep. A lot of virtual currency is the behavior of indivials, enterprises, organizations and institutions
money is built on the basis of an instry, that is, the Internet. The birth of the online game instry is like the early girls' Dance Troupe and QQ farm. Boys play CS, Warcraft, customs clearance and QQ farm to buy dog food. At first, they buy game money, which is the rudiment of virtual money<
in 2008, a pseudonym of "Nakamoto Tsung" published an article on the Internet. His main expression is that the current global payment system is not open, opaque, unscientific, imperfect and backward. The future will be based on the Internet, the birth of a new payment method, based on the point-to-point, blockchain technology support. Because this article is well written, with clear thinking logic, it has led people in the financial instry and investment instry to reprint and forward it thousands of times. In January 2009, bitcoin came into being. In the early days, many people didn't look at bitcoin. At that time, 0.3 cents was equivalent to 20 cents, which was not worth money. At that time, 10000 bitcoins could only buy one pizza. Today, 2016, bitcoin has increased from the initial 20 cents in 2009 to the value of 2723 RMB per bitcoin (data source: real time transaction price at 3:00 a.m. on March 23, 2016)
other well-known digital currencies include Leyte, Ruitai, Weimeng, Yuanbao, Qianjin, etc.
