Blockchain subverts financial industry

1.

blockchain technology has the advantages of being difficult to tamper with and easy to trace. It can play a role in identity information management, trust mechanism construction, and credit information chain of small and micro enterprises

here is an example of a bank in Nanping:

e to the outbreak of online business, the original offline signing method has been unable to meet the needs of the rapid change of the banking business, and the bank's digital construction is imminent, but the bank's risk control department has strict compliance requirements:

< UL >

online business data sensitive privacy, Is the transmission secure

does the electronic signature have legal effect

can electronic evidence be accepted by the court

< / UL >

these concerns have become obstacles for banks to introce e-contracts and carry out business digital transformation

after adopting the unique ENA initiative forensics patent technology of the "real hammer" trusted electronic evidence platform, a bank in Nanping, through the clean server of the notary office, online carries out real-time preservation, storage and certification of the electronic data of the target system, records the whole process of the electronic data from generation, transmission to storage, and finally the notary office issues the forensics preservation report with official seal, The effectiveness of the documents is notarial documents, which can be directly accepted by the court. Because the report is issued by the notary office, it has more credibility than the self certification of the third-party E-contract platform, which solves the concerns of the risk control department of the bank at one stroke. The whole process is online and automated, and the front-end customer operation has no perception

at the same time, combined with the back-end case system of "real hammer" and the outsourcing execution service, the bank realized the rapid dispute resolution of Internet business. It not only ensures the compliance and effectiveness of the electronic contract signing process, but also solves the problem that the bank cases are scattered all over the country and the cost of legal business trip is high; The litigation cycle is long and there is no efficient disposal channel

2. Private chain can effectively solve the efficiency, security and fraud problems of traditional financial institutions, but this change is cumulative. Private chains do not subvert the financial system. However, the public chain has the potential to replace most of the functions of traditional financial institutions through software and fundamentally change the operation mode of the financial system. For example, Huobi launched the public chain project Huobi
chain, trying to build the next generation of self financing system.

Application of blockchain technology in banking

2.1 self regulatory platform

we rarely see a platform that can conct self-regulation without intervention. In all areas similar to the financial instry, central banks and regulators (such as the securities and Exchange Commission) come to set uniform rules and manage them. Blockchain technology makes the system no longer need the supervision from enterprises or government entities, so as to regulate the operation of the system. Blockchain provides a mechanism called "workload proof", which allows each computer node in the system to participate in the approval of each transaction. The system has built-in check and balance mechanism to ensure that no computer in the system can deceive the system. All of these reviews and supervisions are completely automated by the computer. At present, there are many other consensus models that can replace the "workload proof" mechanism, but still retain the core idea that each client or node can manage the system point-to-point. What's more, blockchain makes every element in the system completely transparent. Therefore, for such a large-scale community all over the world, blockchain technology can easily review and manage it - "supervision from the public", thus effectively recing fraud. Imagine how much it can save costs and improve efficiency

2.2 compliance with the law and easy tracking

actors (users) and their behaviors (sending money or assets to others) are recorded on the blockchain. Any transaction between the two parties can be tracked and inquired, and can be proved in court. This is because all transactions need a set of public key / private key to encrypt and decrypt processing and transactions. Once they are added to the blockchain, they are permanent and unchangeable. Any record, once written to the blockchain, cannot be tampered with. Anyone holding assets or digital currency on the blockchain will have their own public key on the blockchain. When a transaction occurs, it needs to be signed by the previous holder who controls these assets using the private key. Blockchain also allows a variety of mechanisms for transactions. For example, it can be set to require two people to jointly sign a transaction. In a system without endorsement of enterprises or government, the legally binding mechanism can greatly enhance the trust factor for the system

2.3 built in business continuity

a global platform can not bear the risk of downtime when concting major transactions. Blockchain, a complete point-to-point network, has many distributed nodes and computer servers to support, which has high reliability. Every node in the system keeps a of the complete blockchain data. This makes the whole network highly fault-tolerant, if any part of a few nodes have problems, it will not affect the other parts of the network continue to operate. This makes it possible to achieve 24 / 7 all-weather operation characteristics like disaster recovery center or database rendancy center without using complex technology

2.4 evolution model without burden

in the system, there are a series of rules and key points to help decide who has the right to approve the transaction and what needs to be reviewed before the transaction is written into the blockchain. Blockchain technology can fork out new versions according to different environments and business model requirements. The new version also needs to conform to the overall concept of blockchain. All these changes must be approved by all members of the system, and everyone can get the same benefits. In addition, these changes will not affect the transactions that have occurred and confirmed on the blockchain. For a system, it has enough robustness and flexibility. People often compare the similarities between the Internet and blockchain, including their growth potential and business prospects. These two systems have very similar characteristics. The Internet does not need or does not have a centralized management department (except for a few for the management of agreed URL and domain name registration), but also has enough rendancy and strong fault tolerance. The Internet has been developing for so many years, from basic text to rich graphics, video, animation, and all this has not affected other existing systems and content. Blockchain has fully proved its function and practicability in bitcoin system. Just as the famous Chinese philosopher Lao Tzu said, "the tree that embraces is born at the end of a tree."; The platform of nine layers starts from the base soil; A journey of a thousand miles begins with a single step. " I think this should be the creed of all the pioneers of blockchain technology
as a rookie of Bubi blockchain, I tell you so much!

4. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

5. Some people predict that blockchain may cause unemployment in banking, auditing and other instries

blockchain is like an account book. Every point in the Internet is being accounted for so that reconciliation can be made. For example, there are people blowing plastic bottles in sweatshops in the south. The workers and the boss keep a record. At the end of the month, the workers made 8000 bottles, but the boss had only 5000. Then one by one. Two people's accounts, of course, need to be signed. But if there are three or more people checking accounts, there is almost no mistake. You can know what it is by studying a pair of details

in this case, it will not be so troublesome to send money to the bank. The Internet is already convenient, from one point on the earth to another, that is, a matter of seconds. How much money has been remitted? There may be countless points in the bookkeeping. In general, as long as there are six points to ensure, the blockchain will regard it as correct. In addition, we can boldly guess that the audit work is unnecessary

blockchain is the underlying technology of bitcoin. Now bitcoin is slowly cooling down, but its methods remain. Now there are applications in voting places. Just like e-commerce, people used to think that they were cheaters, but now they are developing very well.

6. To create a shared network, all banks and users are in the network, and no central system will maintain the account book. Instead, all banks and users in the network have the latest content of the account book, and the account book is jointly maintained by all participants in the network, so as to prevent the loss of the account book caused by the failure of the central system, And if there are participants who want to cheat, others will not agree, which means that each participant will make a contribution to ensure the safety and stability of the account book
is the above technical solution feasible? Feasible; What is the name of this technical solution? Blockchain

blockchain is widely used in China, including electronic payment, financial proct distribution, big data analysis, etc.

7. Sapphire rx560 2G
better or Randy 560 4G

both brands are very good
the price is the same, of course 4G

8. With the rise of China and the increasing trade friction between China and the United States, the exchange rate of RMB against the US dollar has always been a big problem

9. Up? It's a big drop.... Now that the trade war is over, the price has gone up

10. It depends on what you use. If it's playing online games, it's OK. Single machine definitely can't
in addition, 144 is recommended, 60Hz is recommended, and the image quality is good. There is no difference in the actual experience
