The basic characteristics and application basis of blockchain technology: reliable distributed ledger.
Data centered storage has many pain points, and blockchain technology is expected to be a savior.
The concentration of data in the era of big data and cloud computing is high, resulting in excessive control of the cloud center, increased risk of data leakage, and all data passing through the cloud, low efficiency and high cost. Blockchain technology can realize the decentralized storage of data under the premise of ensuring that content is not falsified, and fundamentally solve the above problems. Bitcoin, supported by the blockchain, has been operating safely for nearly seven years, enough to verify the reliability of the technology.
Beyond Bitcoin, the blockchain will embrace the broader world of finance and society in the future .
Now, the blockchain is still mainly used in currency (blockchain 1.0), and will be applied in the financial field beyond the currency (blockchain 2.0), and even beyond the social notarization and intelligent field of the financial sector (blockchain). 3.0).
Overseas traditional industry giants have laid out blockchains since 2014: the world's major banks have established blockchain alliances, Deloitte and other famous accounting firms to develop blockchain auditing technology, Nasdaq's first blockchain securities trading, IBM Joint Samsung layout blockchain Internet of Things. The blockchain is active in business, covering all areas of finance, medical care and music.
Domestic concerns broke out, and financial informationization and Internet of Things were the first to benefit. Domestic attention to the blockchain has started from mid-2015, and entrepreneurship and investment have already begun to show signs. In 2016, related venture capital activities are expected to emerge further. At present, there is no pure blockchain in A-shares. From the perspective of technology relevance, we expect financial information technology and IoT manufacturers to expect advanced military forces in this field.
Our preliminary exchanges found that investors are relatively new to the field and even confuse the blockchain with Bitcoin. Because of the policy barriers of Bitcoin and the application of blockchain technology, there is a clear expectation difference. If market risk appetite increases, blockchain technology is expected to become a new TMT outlet, with a prominent investment value.
Catalyst: The central bank supports the development of digital currency, and blockchain entrepreneurship and investment events are intensive.
Risk warning: Technology landing needs to be improved, and overseas big companies compete with local technology companies.
Blockchain hopes to subvert cloud computing to reconstruct the whole social data architectureCloud computing technology is one of the most disruptive technologies in the past decade. Traditional IT giants HP and IBM have lost ground under the general trend of cloudization. The cloud of payment, consumption, and data storage has also brought consumers a convenient experience that has never been seen before.
However, cloud computing is not perfect. As a kind of "centralization" technology, cloud computing requires local data to be uploaded to the cloud for calculation and storage, which not only increases the operating burden and cost of the entire system, reduces the efficiency of the system, but also makes the user's data more vulnerable to centralized attacks. Privacy is easier to expose. Blockchain technology can solve these pain points by establishing a reliable, reliable, and secure decentralized system.
In addition to applications in the payment and finance fields, the blockchain has applications in the fields of medical, data, copyright management, and socialization, and it is expected to reconstruct the data structure of the entire society.
At present, overseas blockchain technology exploration is becoming more and more mature. Giants such as IBM, JPMorgan Chase and Nasdaq are leading the transformation. Entrepreneurship in the fields of medical care, notarization and socialization has blossomed, while domestic central banks, ABC, Ali, Wanxiang and other giants have also Shows interest in blockchain technology. We believe that 2016 is the year of domestic blockchain technology, related entrepreneurial and investment activities will begin to emerge, A shares will also begin to pay attention to this new technology field, financial information technology and Internet of Things related targets are expected to take the lead in the coding block chain.
Data centered storage three challenges highlight the pain points in the blockchain“Big Data†centralizes data and facilitates massive invasions of privacy. The Internet + enterprise's central database has a large amount of user data, and the open cloud platform actually makes the data more highly concentrated. Once the data center is attacked, a large amount of private data may be compromised. And as people become more exposed to privacy on the Internet, they are paying more and more attention to privacy.
Blockchain technology minimizes the possibility of revealing personal privacy. With blockchain technology, personal identity information is only visible to itself and enables true decentralized storage. Especially for the sensitive data fields such as medical health, the new decentralized data security technology in the future is likely to subvert the existing centralized big data model.
Establishing data technology that cannot be tampered with is extremely important for financial institutions to strengthen internal management. Value-related data, such as deposit balances, are more attractive to tampering. All the data of the traditional bank is stored in the data center, and the bank has strong control over the data, which makes internal tampering more convenient. The data shows that although the phenomenon of tampering with the amount of misappropriation within the bank has rarely occurred, the amount involved in a few cases is huge. In addition, Sony and other companies involved in online payment have repeatedly experienced credit card information disclosure, resulting in major loss events such as user credit card theft.
Even if there is no human tampering, if the central database is physically destroyed, the destructiveness of the entire financial ecology is enormous.
Blockchain technology builds credit on computer and mathematical principles to eliminate human manipulation. The unique workload proof mechanism and consensus mechanism in blockchain technology eliminate the possibility of tampering with data. Moreover, distributed accounting can spread the risk of damage to the central database and ensure data security. Therefore, there is a high demand for blockchain technology in the financial sector.
Massive data cloud storage costs are high, and Internet giants such as WeChat limit the size of data storage. The amount of data generated by the Internet every day is huge, and storing multiple servers in the center requires multiple servers. The cost of purchasing, running, and maintaining the server is very high. Centralized systems are less efficient to process. All data is uploaded to the center for unified processing, and the center load is large. WeChat recently stopped the cloud upload storage function of user chat records, because hundreds of millions of users may record hundreds of millions of GB (hundreds of petabytes) of data, which poses a huge challenge to Tencent's bandwidth and storage capacity.
The distributed storage principle of blockchain technology increases efficiency while reducing costs. Through the blockchain technology, each node in the system can be used as a server to achieve network autonomy and reduce the need for centralized cloud data storage capabilities. Blockchain technology has application requirements in the fields of automated auditing and IoT self-organizing networks.
Blockchain technology verification is feasible to solve data tampering problems fundamentallyThe blockchain was born together with Bitcoin. Bitcoin is a truly decentralized peer-to-peer electronic currency trading system, and blockchain technology is the core technology to ensure the safe operation of the Bitcoin system. Blockchain technology can ensure that the decentralized electronic money system realizes self-management and eliminates the problem of identity forgery and duplicate payment. Since its establishment in 2009, the Bitcoin system has been operating independently for nearly seven years, showing the reliability and stability of its technology.
In September 2014, Paypal, the world's second largest online payment network, announced that digital goods in the United States can accept bitcoin payments through Paypal. Global Internet websites and service providers have a high degree of acceptance of Bitcoin. In the absence of third-party supervision and maintenance, the only mechanism that can guarantee the security of large-scale transactions is the blockchain.
Blockchain attention is now higher than Bitcoin. People are gradually paying attention to the blockchain technology behind Bitcoin. Because it can implement a completely self-contained system like the Bitcoin system, it has begun to touch the nerves of large investment institutions. At present, blockchain technology has a tendency to be extracted from the bitcoin system and applied to other fields.
To date, the Bitcoin system is the only mature application of blockchain technology, so the report will illustrate blockchain technology in conjunction with the principles of the Bitcoin system.
