Blockvc and bitcoin

1. Q: What is blockchain technology? A: Blockchain technology can be understood as a public accounting mechanism. It is a technical solution rather than a specific proct. The basic idea is to establish a set of public account books on the Internet, in which all users in the network keep accounts and check accounts together, so as to ensure the authenticity and non tamperability of information. The reason why it is called "blockchain" is that the structure of blockchain storage data is composed of a chain of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time, and the chain continues to grow over time. Q: What is the relationship between blockchain and bitcoin? A: Bitcoin used to be one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. It can be said that bitcoin is a "killer application" of blockchain idea. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin. Q: What are the technical features of blockchain? A: Based on open source software and peer-to-peer network, blockchain can bring more advantages than traditional network in currency related fields such as transaction payment. These advantages include: decentralization, no need to trust the system, disintermediation, tamper proof, encryption security. Q: How does blockchain technology improve the authenticity and non tamperability of data? A: The newly added data blocks are linearly added to the end of the original block in chronological order, which constitutes the blockchain. In this process, the data is distributed in each computer. This decentralized storage method improves the authenticity and non tamperability of the data. When a transaction occurs, users all over the world can act as regulators. If we do not recognize the legitimacy of the transaction, the transaction cannot be concluded, and the data on the blockchain is maintained by us collectively. Q: Is there any potential defect in such a brain burning "blockchain"? A: Blockchain also has some defects to be solved, such as security risks, work efficiency and resource consumption. Since the supervision of blockchain depends on all nodes in the network, theoretically speaking, if you master more than 50% of the computing power of the whole network, you will be able to successfully tamper with and forge blockchain data. Secondly, e to the distributed storage, each node in the blockchain needs to keep a database, and any transaction in the network needs to be authenticated and recorded by other nodes, so the efficiency of the system is low. Finally, because the operation of the blockchain relies on the computing power contributed by the network nodes, these computing power do not proce actual social value, so it is generally considered that these computing power resources are "wasted". Application of blockchain in various fields when blockchain technology is published, many people think it is possible to realize DAC. DAC (full name) can be translated into distributed autonomous system, which refers to an organization system that runs autonomously without intervention and management through a series of open and fair rules. DAC has many forms. It may be a digital currency, a system or an entity, or even a driverless car. This kind of organization system can provide valuable services for customers in the form of currency transfer (such as bitcoin), asset transaction, domain name service, or any other business model. Therefore, through the idea of information sharing, blockchain technology is likely to bring profound changes in cost rection and security improvement to various instries. Application scenarios that existing blockchain technology can achieve: proof of existence can be used to confirm rights in the field of Internet finance, that is, blockchain can really realize "proving your mother is your mother". The smart contract guarantees the validity of the contract, such as the generation required by the electronic signature law; Reliability of methods for storing or transmitting data messages; The reliability of the method of maintaining content integrity; The reliability of the method used to identify the sender. The blockchain of the Internet of things can solve the problem of the coding standard interaction interface of the Internet of things. When an e-signature is signed by identity verification, the signature data is only under the exclusive control of the signer. Any changes to the e-signature after signing can be found, and any changes to the content and form of the data message after signing can also be found. The market forecasting community, August, is an example. Anyone can access and use August anywhere in the world, which may bring unprecedented liquidity and trading volume to the market. Asset trading NASDAQ OMX Group Inc is testing blockchain technology, which NASDAQ believes has the opportunity to transform traditional financial trading methods into bitcoin like ones. The bitcoin mode of e-commerce can be applied directly. Is it possible for e-commerce to become a "harmonious" market without supervision? Social news magmavc has invested $400000 in getgems (formerly known as gems), a start-up project for decentralized social communications applications. File storage directly impacts and even subverts the traditional cloud computing architecture. Chain, a data API blockchain API service provider, has received a $9.5 million investment led by Khosla ventures. Wall Street's financial companies are investing in blockchain and seizing the beach. Visa, NASDAQ and Citigroup also invested in chain, an old Jinshan blockchain start-up, with a financing amount of US $30 million. In the financial field, what can blockchain do? Specifically, in the financial field, in addition to providing a trading platform for bitcoin, Jiuding investment believes that blockchain technology can also greatly improve various asset trading systems other than the existing digital currency. For example, it plays an important role in the post transaction market proceres such as the liquidation and settlement of financial derivatives, foreign exchange, private equity, energy credit linked investment procts and other assets. In terms of speed, the time required for settlement audit in the U.S. securities market is 2 to 3 days. The application of blockchain technology is expected to rece the settlement audit time from hour level to minute level or even second level, thus recing the settlement risk by 99%, and recing the capital cost and system risk. In the blockchain, transaction confirmation and settlement are carried out at the same time. After the node transaction is confirmed by the system, it is automatically written into the distributed ledger, and the corresponding distributed ledgers of all other nodes are updated at the same time. The automatic operation mechanism can greatly shorten the settlement cycle. In terms of expenses, under the current settlement mechanism, in order to achieve a shorter settlement cycle, it is necessary to increase the settlement cost and initial investment expenses significantly. The emergence of blockchain technology makes it possible to rece the settlement cycle more efficiently and quickly, and rece the transaction intermediate proceres, so as to save a lot of money, which is the market space of the related blockchain instry. In terms of security, the integration of blockchain technology into smart contract technology can process complex derivatives transactions programmatically, making clearing more standardized and automated. The time linear stacking feature of the block itself can help the regulators identify and discover illegal operations. At the same time, the smart contract can change the compliance inspection into automation and minimize the possibility of violation from the beginning of liquidation. The 24-hour uninterrupted operation of blockchain technology can also make the data exchange processing of Pan state exchange more stable and reliable. In addition to securities transaction settlement, blockchain can also be used to register and issue digital asset ownership. Blockchain technology can greatly enhance program automation, while smart contract can write many complex derivatives trading terms into the registration and issuance program supported by blockchain technology. When a transaction occurs, blockchain network can quickly and correctly execute. In November 2015, LINQ, a new blockchain technology project cooperated by Nasdaq and chain, has completed the first private equity transaction using the blockchain based issuance and trading platform. The application prospect of blockchain in the field of accounting has also attracted the attention of a large number of people in the instry. Accounting, auditing and compilation cost a lot for global enterprises and the four accounting firms. Automatic accounting based on blockchain technology can greatly rece the relevant costs. The company does not need to recruit special auditors to audit the account book, and all transactions can be stored in the internal blockchain. Due to the irreversibility and time stamp function of the blockchain, the external auditors and regulators of the four major accounting firms can monitor the company's account books in real time by tracking these blockchains. At the same time, the institutions can greatly rece the dependence on the auditors to audit financial transactions and make the audit business more efficient. With the increasing maturity and application expansion of blockchain technology, blockchain start-ups in developed countries have sprung up. At present, the world's leading blockchain companies generally focus on transaction, payment, clearing, Internet of things and other pain point businesses. Some companies have achieved a certain scale, and have developed a relatively clear business model. At the same time, many companies have extended their business in the blockchain instrial chain, covering payment, transaction, risk control, etc., making full use of the multi-point coordination effect. At present, Jiuding investment is also focusing on the projects and applications of various blockchain technologies.

because those who come in after mobile phone mining will be cut leeks

precautions:

1. In the past two years, various myths about blockchain "overnight wealth" have been constantly staged, and "mining" cryptocurrency has become a new trend of wealth, and mobile phone mining is becoming more and more popular

2. There will be special mining machines for real mining. After all, every mining machine is not cheap now. Mobile phone automatic mining can be obtained at a very low price. What you dig is not bitcoin. Basically, the counterfeit coin you send is not worth money. At that time, you will still be cut leeks

3. Blockchain is its underlying application technology, and digital currency is its currency. Its practical application has little impact on the fluctuation of digital currency
when the economy is stable, it doesn't rise. When the economy is in turmoil, people begin to store digital currency. Of course, it is convenient for some corrupt elements
now the economy is stable, the digital currency is in a bear market, the financial crisis, the crisis, and only when there is a crisis can there be an opportunity. At that time, the rapid growth of bitcoin was the opportunity in the financial crisis. Don't worry, there will be a bull market in digital currency, which is expected to come in the second half of next year
4. AUV public chain adopts the consensus mechanism of activity proof mechanism, all data are open by default, and its own security is generated through its publicity
5. Okex is a good platform with high security and the largest trading volume in the world. It supports multi currency leverage trading, legal currency trading and contract trading.
6. Bianews reported on July 1 that the opposition team of fire coin super node is expanding. After node capital Du Jun and dfund Zhao Dong announced their withdrawal from the fire coin super node, more and more people in the circle criticized the fire coin hadax and announced their withdrawal from the super node

Zhang Li, partner of linkvc, announced on June 30 that there are no rules for the selection of fire coin super nodes, and some departments of fire coin are "bureaucratic"

Li Mingxuan, co-founder of blockvc, also announced in his circle of friends on June 30 that hadax's node stratification is not an objective fund rating, but a subjective rating made by hadax out of its own control

coin letter capital announced on June 30 that it would quit the fire coin super node and stop participating in the voting process on fire coin

at the same time, end capital also issued a statement saying that it would withdraw from the fire coin super node and replace it with Hunter capital

according to the report of liandede, we have checked with the relevant personnel of Huo coin that Huo Li, the vice president of global business of Huo coin, has been removed from the post of vice president, and hadax will be in the charge of Zhu Jiawei, the COO of Huo coin.com

on June 30, Du Jun, the founder of node capital, announced on wechat that he would quit the fire coin super node and would no longer participate in any project voting of hadax<

Zhao Dong, founder of dfund, also sent a message on Weibo on June 30, saying that dfund will quit the hot money super node from now on and will no longer participate in any hadax voting

after the founders of node capital Du Jun and dfund Zhao Dong successively announced their withdrawal from the fire coin super node in public channels, the friend circle of fire coin founder Li Linfa responded that hadax must be demolished and rebuilt, and there will be a big upgrade next month, and said that in the process of upgrading, he was sorry for the poor communication

why, on the same day, after node capital, dfund, coin letter capital and end capital announced their exit from the fire coin super node, linkvc partner Zhang Li and blockvc co-founder Li Mingxuan also expressed their views on hadax in the circle of friends? The answer may be to change the rules of fire coin super node< In addition to node capital and dfund, blockvc and linkvc are also divided into the preferred node level

the general node and the preferred node have different rights. The project party must have the support of the general node to board the fire coin, but the preferred node cannot promote the project party to board hadax. At the same time, the fire coin also developed an end elimination system, the low score will be demoted to the candidate node with low threshold and less power

perhaps, the ever-changing voting rules and discriminatory agency ratings of hotcoin really disappoint the festival members. The blockchain technology itself is decentralized, which obviously runs counter to Nakamoto's concept of decentralization

maybe the super node mode itself is a kind of deformity. Centralized exchange, let the super node recommend their own support projects, or centralized

once the fire coin changes the rules, it will inevitably touch the interests of the super node, and the formation of the resistance camp is inevitable.
7. Now it is entering the Internet Finance
in 2014, Internet finance has entered a period of barbaric growth: P2P online lending platforms have emerged at an amazing speed, and at the same time, they have also witnessed the tide of bankruptcy After a fierce boom, the income of "Baobao" procts graally flattened; There are more and more ways to play crowdfunding, involving more and more fields, and many VC and PE have entered the field of crowdfunding entrepreneurship... After a year of carnival, in 2015, the entire Internet finance instry will enter a stage of precipitation and rational thinking, showing some new development trends
P2P: precipitated from the noise
in 2014, the P2P instry was very busy, a large number of P2P platforms experienced from birth to death in a year, and the whole instry realized the self elimination of the instry in the bustle of "you sing, I come on stage". In 2015, after the bustle of P2P, it will graally return to rationality, showing the development direction of the instry
1. Rapid reshuffle of the instry
in 2014, on the one hand, a large number of online platforms emerged in the P2P instry, on the other hand, "bankruptcy wave" swept the whole instry. This is a normal phenomenon of survival of the fittest in the early development stage of the whole instry, which is related to the irrational pursuit of high interest rate by investors, lax policy supervision and low illegal cost
at present, most of the P2P platforms are still lack of qualification certification. In the P2P instry, the voice of policy supervision has been continuous. According to the timetable disclosed by Yang Xiaojun, deputy director of innovation Department of CBRC, P2P regulatory rules may be issued in early 2015, when a number of non-standard P2P platforms will face elimination
on the other hand, a lot of capital flows into P2P instry. In 2014, according to incomplete statistics, from January to October alone, more than 30 P2P platforms have been invested. The strength of these P2P platforms that attract capital investment will be greatly improved, accelerating the survival of the fittest in the instry
2. The trend of de guarantee
in 2014, the de guarantee of P2P instry has been an endless topic in the instry. At present, the cooperation between P2P platform and guarantee company has become a common phenomenon, but this mode has become an obstacle to the development of P2P instry, and de guarantee has become inevitable
some P2P platforms do not have the ability of risk control and management, but they can still attract a large number of investors because of the guarantee companies as a shield. Once there is a problem with the guarantee company, the P2P platform will be vulnerable and fall into disrepair instantly, resulting in the collapse, running and other vicious events. Secondly, the guarantee cost of the third party guarantee company is very high, usually about 2% - 5%, which indirectly increases the financing cost. From these two perspectives, the guarantee system has become an obstacle to the self-development of P2P instry
3. Big data credit reporting becomes the core competitiveness
the de guarantee of P2P platform means returning to its essence as an intermediary. As an online loan intermediary platform, risk control ability will be its core competitiveness in the future
now some P2P platforms are trying to build their own databases by using the data left by customers on social media and e-commerce trading platforms. In the future, with the help of technology and big data, some P2P online lending platforms will establish their own data-based risk control model, and use big data to analyze and judge whether indivials or enterprises have the ability to repay. This will also become the core competitiveness of P2P platforms. Even in the future, some P2P platforms will transform to professional credit agencies after they have enough strength in big data credit
4. Instry refinement
at present, the P2P instry has become a red sea. In the fierce market competition, it is the key to make use of their respective advantages to refine procts and take the differentiation route in the future
at present, the scale of the whole P2P market is constantly expanding, and the professional market segments have begun to be divided. The business model of monopolizing the market will be difficult to sustain, and a single P2P platform has no ability to cover the major professional markets. Only refinement and specialization is the only way for P2P enterprises to survive
in fact, the leading P2P enterprises in the instry have their own accurate market positioning. Some platforms mainly finance for environmental protection enterprises, some cooperate with auction houses to promote collection financing, and others focus on financing for medical, automobile, tourism and other instries< On April 19, 2014, the crowdfunding platform announced that it would abandon the crowdfunding mode and become the first platform of intelligent hardware. In the future, the crowdfunding platform will provide a full range of crowdfunding support for some excellent crowdfunding projects, including project packaging, media public relations, investor recommendation, customer satisfaction, etc Channel docking "green channel" and a series of professional customized services. It's not only the roll call time, but also the equity crowdfunding platforms, such as angel collection and cloud funding, all choose to tear off the label of crowdfunding and emphasize their non crowdfunding attributes
this is not the decline of crowdfunding, but the inevitable development of crowdfunding platform to a certain stage: crowdfunding platform will no longer be limited to a single financing link, but will extend services to the whole chain. This not only grasps the needs of the project side, but also helps to protect the interests of investors. For crowdfunding platform, it also breaks the shackles of profit model
mobile payment drives the development of virtual currency
with the breakthrough of NFC (near field communication) technology, the high-end models launched by apple, Samsung and Huawei have fully covered NFC functions, especially the apple pay launched by iPhone 6. With the market position of iPhone, it has a unique advantage in the mobile payment market, and may be combined with virtual currency, Challenge traditional paper money
it is understood that 220000 businesses in the United States have joined the camp of applepay, accounting for 5-10% of all businesses in the United States; Twelve banks announced a partnership with applepay, which is responsible for 83% of credit cards in the United States. Apple pay is expected to become the number one mobile payment company
virtual currency will also benefit from mobile payment. Virtual currency is rooted in the Internet. As long as consumers have mobile devices, they can exchange virtual currency. The emergence of applepay will cultivate consumers' habit of mobile payment
compared with traditional currency, virtual currency has the characteristics of decentralization and high mobility. It does not belong to a certain bank and does not need to be audited and certified by financial regulators; As long as the technical support, we can transfer and trade virtual currency through simple operation. These are the characteristics of virtual currency superior to traditional currency. The rapid emergence of mobile payment makes virtual currency a great leap forward
now, bitcoin analysis start-ups such as blocktrack and coinalytics have obtained financing, which will help people better understand bitcoin. When people find the advantages of virtual currency more and more, maybe traditional paper money will be graally replaced
the first year of mobile Internet Finance
If 2013 is the first year of Internet finance, 2015 may usher in the first year of mobile Internet finance

at present, the third party payment represented by Alipay and fortune paid has been transferred to Alipay wallet and WeChat. According to the open data of Alipay wallet, Alipay mobile payment day has more than 45 million transactions, accounting for more than 50% of Alipay's total share. 97% of the users operate on their mobile phones when transferring money. In the past, traditional financial procts also transformed from financial page to app< Grass root mobile phone is another catalytic factor of BR / mobile internet financial mobility. Alipay's procts are starting to spread to the cock silk crowd, and make financial management and daily life of the public connect. People can invest and manage money, mobile payment and insurance whenever and wherever possible through smart phones, pad and other intelligent terminals. The closer an area is to daily life, the more mobile it is.
