The future bank of blockchain
Publish: 2021-03-22 23:34:13
1. blockchain is a kind of technology. "In the simplest and most popular way, blockchain technology is everyone bookkeeping, or distributed ledger."
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.

2. The decentralized blockchain currency wallet we use is actually just a blockchain software. Your currency is not stored in the wallet company, nor in your mobile device. It is still in the address of the blockchain network. The wallet just shows you all kinds of code of the blockchain through the server, establishes a channel to send all kinds of operation instructions to the blockchain. Blockchain application is very hot now. There is a SMIC blockchain service platform project initiated by Changsha high tech Zone, which is blockchain + public service mode, and is soliciting enterprises to join the chain.
3. Blockchain will not lead to the disappearance of banks. Blockchain will only improve the business of banks
at present, some well-known financial institutions in the world have begun to pay attention to blockchain and have carried out corresponding research and development. But banks will only make use of blockchain and will never let blockchain replace themselves
the underlying technologies of bitcoin, Ruitai and Laite are blockchain, but no one can replace the bank.

4. Before, when we talked about decentralized applications, we always thought of foreign procts, such as Ethereum. But when we talk about this topic today, I think more about China's own Asch, a new generation of decentralized application development based on side chain technology<
arch is a decentralized application development, and it is also the first decentralized application in China. Its purpose is to help developers quickly create decentralized applications. The system is easy to use, flexible and safe
in terms of mode, it is similar to Ethereum and belongs to blockchain service, but the implementation mechanism is quite different. Taking Ethereum as an example, its biggest feature is that it greatly expands the functions of the script engine, adds new instructions such as reading blockchain, charging and jumping, and relieves stack memory, function call depth and script length restrictions. However, this method has a big disadvantage that the application code itself and the data generated by the application exist in the same blockchain, resulting in the rapid expansion of the blockchain
but arch is different. Its extensibility is not realized by transaction script, but by side chain. There is a main chain and several side chains (mainly provided by developers) in the ash system, but each chain only supports a limited number of transaction types. The logic of transaction or contract is written directly by the host language, not by the transaction script
the advantages are as follows: firstly, it reces the difficulty of contract programming; secondly, it avoids blockchain expansion; thirdly, each application can customize personalized blockchain parameters<
ash does not directly crypti (decentralized, blockchain based app store) or lisk (it is a new generation, allowing JavaScript development and distributed applications to use an easy-to-use, fully functional ecosystem), But it will refer to crypti's architecture and reuse some of its code, but not too much
there are two main differences.
crypti uses dpos, on which we add pbft algorithm to enhance consistency and rece double payment risk
we use C + + language to write some key moles, and nodejs is still used to write the non performance hot parts.

5. Now, Bank of Changsha also cooperates with a public platform of SMIC blockchain, which seems to be a blockchain loan for small and micro enterprises.
6. There are no people in the empty mountain, but people's voices are heard.
7. Theoretically, blockchain technology will be the future of financial services, but in fact, it is still a long way to go. However, domestic European crowdfunding and international NASDAQ are already trying blockchain projects
the invention and development of blockchain and its related technologies benefit from the rapid development of computer instry: 1. The processing speed of computer chips has been greatly improved; 2; 2. The cost of storage devices is greatly reced. Blockchain technology derived from a variety of technologies, such as: smart contract; Digital rights management; Internet of things (IOT) innovates business model; Private data protection; Distributed storage of digital content; Voting; Credit system strengthening and so on<
financial services instry can benefit from blockchain technology
subversive potential
Professor Peters and panayi of University of London believe that "blockchain technology has the potential to subvert the world banking instry, which can improve and promote services such as global currency exchange, smart contracts, automated banking books and digital assets." In addition, there are "blockchain technology can be applied to many fields, such as transaction processing program, government cash management, commercial bank account book management, financial asset clearing and other fields."

8. The word subversion is a description of media's unscrupulous and eye-catching behavior. The correct posture is that blockchain will help the banking instry improve its security and efficiency
traditional banks are centralized account books, and regulators have a general ledger in their hands. We need to use a sum of money. The general ledger records the information about the change of money. If the general ledger server is hacked, or someone who has the right to modify the account book has done something wrong, then our deposit data will be wrong. That's why some customers' deposits have disappeared
the blockchain is a distributed ledger. On the blockchain, the synchronized ledger is stored on the global nodes. If it is to be modified, the technical rules of the blockchain force that more than 51% of the global server nodes must be modified. The theory is feasible, but the fact is not
banks close down at 16:30 p.m. every day. One of the things they have to do is to centralize and exchange transaction data among banks. With blockchain, this link is saved. Direct point-to-point real-time exchange
when you go to the bank to open an account and do business, the information is repeatedly provided again and again. If the user uploads the instrial and commercial data and personal data to the blockchain, a two-dimensional code can download the user's information, which is more secure and accurate, saves a lot of trouble, and greatly improves the security and efficiency

As a traditional financial institution, banks are the most active Pathfinder in the field of blockchain. In recent years, many banks at home and abroad have applied blockchain technology to credit, clearing and other fields. The unique trust mechanism of blockchain is regarded by banks as a key technological breakthrough in innovating risk management and simplifying transaction process. However, as an emerging technology, blockchain ecology is still in the process of establishment, and its application is very limited. Many problems still need to be solved graally in the development
"at present, blockchain can't run high-frequency and concurrent transactions, and network speed and computing power can't support it. For example, in the field of payment, if it is online shopping, it can be realized; If it's high-frequency futures trading, it can't be done. " Huang Zhen said
JIANG Peng said that at the beginning of designing the blockchain system, China CITIC Bank carefully demonstrated the business links suitable for the use of blockchain
"from the global experience, it is not suitable to use blockchain to build a large and complex system. Instead of trying to solve all problems with blockchain, we should focus on solving the core problems. It's time-consuming to build a too complex system. The technology is developing so fast that before the old system is finished, it will face the iteration of new technology. " Jiang Peng said
the idea of "only solving core problems" ensures that after the blockchain goes online, the relevant business operations of branches of China CITIC Bank can be upgraded without process transformation
Fan Bin said frankly that it will take time for banks to fully apply the blockchain, and IBM's investment in the blockchain open source community will continue, on the one hand to cultivate the market, on the other hand to compete for the commanding height of the blockchain platform. With the rapid iteration of blockchain technology itself, there is still a lot of imagination for financial institutions to use this new technologythe content comes from Xinhuanet
