How does blockchain help organizations share data

Publish: 2021-05-08 00:17:17
1. 1. What is the technology of blockchain?
2. Of course, this is OK
first of all, blockchain is actually a centralized database or a decentralized database, and all technical units are for better maintenance of the public database. Each node keeps a of data independently. Consensus algorithm is used to achieve the data consistency of the node's account book, and cryptographic algorithm is used to ensure the data can not be tampered, and the data can not be tampered and the security of data sending and receiving; Through the script system, the expression scope of account data is expanded
secondly, financial sharing center involves a large amount of financial data. We can combine the technical characteristics of blockchain with Financial Sharing Center. Next, I will combine the technical characteristics of blockchain with Financial Sharing Center
① distributed storage is a distributed database of the blockchain, and each node keeps a of the data independently. If this is combined with the Financial Sharing Center, The users who can join the "financial data on the chain" in the financial sharing chain are equivalent to the "nodes" in the blockchain network, and each user can keep a of the financial data separately, so as to achieve the purpose of sharing
② tampering is not allowed. A very important feature of blockchain technology is that the data cannot be tampered, To ensure the security of a data in the Financial Sharing Center, we need to consider the security as long as the financial data is involved.
of course, before doing the Financial Sharing Center, you must determine your specific needs, if necessary, first write a framework of the whole project, and then find a formal blockchain development team according to the needs, To help you develop this "Financial Sharing Center", we must pay attention to that before formal cooperation is reached, don't disclose the information of your project casually, in order to prevent the same kind from being copied.
3. In view of the security characteristics and shortcomings of the existing blockchain technology, we need to build a security system around the physical, data, application system, encryption, risk control and other aspects to improve the security performance of the blockchain system as a whole
1. Physical security
the network and host running the blockchain system should be in a protected environment. According to the regulatory requirements of specific business, the protection measures can be used to protect the physical network and host by means of VPN, firewall, physical isolation, etc
2. Data security
in principle, the data exchange between nodes of the blockchain should not be transmitted in clear text. For example, asymmetric encryption can be used to negotiate key, and symmetric encryption algorithm can be used to encrypt and decrypt data. The data provider should also strictly evaluate the sensitivity and security level of the data, decide whether to send the data to the blockchain, whether to desensitize the data, and adopt strict access control measures
3. Application system security
application system security needs to start from the aspects of identity authentication, authority system, transaction rules, anti fraud strategy, etc.
relevant personnel, transaction nodes and transaction data involved in application operation should be controlled in advance and auditable afterwards. Taking financial blockchain as an example, consensus algorithm with stronger fault tolerance, anti fraud and higher performance can be adopted to avoid joint fraud of some nodes
4. Key security
to encrypt the communication data between the blockchain nodes and the key to encrypt the data stored on the blockchain nodes, the plaintext should not exist on the same node, and the private key should be properly saved by the encryption machine. When the key is lost or leaked, the system can identify the relevant records of the original key, such as account control, communication encryption, data storage encryption, etc., and implement response measures to make the original key invalid. The key should also be managed strictly in the life cycle, and should not be permanently valid. It needs to be replaced after reaching a certain time cycle
5. Risk control mechanism
there should be careful detection measures for the network layer, host operation, data access of application system, transaction frequency and other dimensions of the system. For any suspicious operation, alarm, record and verification should be carried out. If illegal operation is found, loss assessment should be carried out, remedial measures should be taken at the technical and business levels, and security measures should be strengthened, And trace the source of illegal operation to prevent further attacks

4. Generally speaking, the essence of blockchain should be weak control, sub center, autonomous mechanism, network architecture and coupling connection. The essence of blockchain should be a new social structure in the era of information society, which is completely different from the instrial society. The five core points of blockchain are in common with sharing economy to some extent. The essence of the sharing economy is to abandon the old development mechanism, no longer focus on concentration, and instead use the decentralized social resources in a point-to-point way to let the participants participate in, and pay and benefit in different ways
the two Internet hotspots, blockchain and sharing economy, happen to have sufficient "cooperation space". With the development from theory to practice, the instry has made a lot of bold explorations about the two, and even some challenges to the traditional business model have emerged. In this way, the sharing economy with blockchain will be a new business model and a new subversion of interpersonal relationship. I plan to invest in the blockchain instry. After all, in the Internet era, I searched Guangzhou Xuanling Technology Co., Ltd. on the Internet and looked at the webpage. They are a company engaged in software blockchain intelligent contract development. There are many development cases, and the team is also strong.
5. Bitcoin is characterized by decentralization. As long as you have a network and can use your wallet, you can use it regardless of national boundaries. If you don't understand, maybe you can go to Babbitt to find a master.
6. Guess money network did not say what role..... It's just for gambling

cough, this property should be similar to body color
you will ask: after gambling? How to deal with a lot of guessing coins
I would say: maybe there will be some useful official notice in the future, such as activities ring the world cup
[reward method]

after the world cup, the top 9 users in the quiz list can get the reward from the post bar. At the same time, in addition to the top 9 netizens, we will randomly select 20 bar friends from the top 100 bar friends in the ranking to give out lucky prizes. Come and join us<

[award setting]

one first prize, three second prizes for Sony dsc-tx7c digital camera, five third prizes for iPod new shuffle 4G MP3, 20 lucky prizes for Internet travel storage bags, Logitech M215 wireless mouse, and the support for the event The final right of interpretation of this activity belongs to aitieba, and network employees are not allowed to participate in the activity to receive awards.
7. A new type of blockchain has been developed to make the public transactions used for verification contain only part of the information
Cooper takes interest rate swap as an example. Dodd Frank requires both parties to record 140 data fields. However, in the blockchain, other banks can only see specific data points, and they may just display the code of transaction nature and price range
at the same time, the blockchain will store complete transactions, which can only be seen by relevant parties and regulators with monitoring obligations
of course, the most important thing about blockchain is that it can not be tampered with, and the protection of intellectual property rights is very important, such as the recent foreign project of decent, which is a distributed content publishing platform.
8. The draft of the "fourteenth five year plan" points out that seven key instries of digital economy, such as instrial Internet, blockchain, artificial intelligence and so on, as well as digital application scenarios such as intelligent transportation and intelligent energy, should be further defined, and "accelerating digital development and building digital China" should be regarded as an independent chapter, from creating new advantages of digital economy to speeding up the construction of digital society, From improving the level of digital government construction to creating a good digital ecology, this paper outlines the new prospect of Digital China Construction in the next five years. In 2025, the added value of core instries of digital economy will account for 10% of GDP
through consensus algorithm, the user data can be updated synchronously among judicial nodes such as notary office, Arbitration Commission, Internet court, judicial identification Institute and right institution on the security chain, so that each node on the security chain can realize real-time exchange of data and information, and effectively improve the judicial credibility of the blockchain data
based on the mode of "blockchain + judicature + application", e-security deeply arranges e-signing, and helps enterprises transfer traditional offline paper contracts to online signing by means of professional underlying data storage capability, full evidence chain technology and post signing judicial services, providing real name authentication, E-contract, signature management and other services
, the use of blockchain technology for the original works of online right confirmation, infringement detection and infringement forensics, as well as online right registration and other intellectual property protection services. It provides online arbitration filing application, agent execution, direct evidence to arbitration commission and other services for enterprises and indivial users. At the same time, it can also provide the notary office with the construction of Internet notary system, notary intelligent terminal and corresponding customized services, and help the notary office to comprehensively transform and upgrade its business. At present, it has successfully provided judicial services such as Internet notarization system construction for many notary offices. And other application scenarios, lead the blockchain to different instries and fields, provide full supporting solutions, and accelerate the rapid implementation of blockchain in the whole instry. As the cornerstone of digital economy, blockchain technology plays an important role. Through "blockchain +" to quickly complete the transformation and upgrading, release new momentum for the development of digital economy.
9. I just checked it on the Internet and said that it is the same major shareholder (Zhuo Er or something) as the P2P platform "jiashiliu" which announced the retirement of "charge and raise difference" this year.
