Blockchain of Changliang Technology

1.

blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

extended data:

the evolution mode of blockchain is as follows:

& 9642; Blockchain 1.0 - digital currency

▪ Blockchain 2.0 - digital assets and smart contracts

▪ Blockchain 3.0 - Implementation of distributed applications in various instries

blockchain features:

1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system

2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work

The information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. 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. Therefore, the data stability and reliability of the blockchain are extremely high

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

The most significant applications are

1. Think about using blockchain in enterprise applications to provide more flexible, safe and efficient business processes and distributed, independent markets. Blockchain allows asset owners to track and trade valuable things, such as outstanding invoices, on a transaction "chain" that is more secure, transparent, private and self-coordinating. This capability improves the speed and flexibility of cash and asset management. For example, you are afraid to buy fake things, because a manufacturer transfers proction to several middlemen, and then you buy through middlemen, not manufacturers. If all the data is distributed, point-to-point and transparent, you can buy and pay directly from the manufacturer

The automation market of other assets will be diversified. In essence, because the software itself is controlled and open architecture, and visible to all transaction participants, the transaction based on blockchain can rece the demand for third-party supervision. If the enterprise can publish the value information to multiple potential buyers, and for all buyers, the content can be trusted and visible, and the seller can't sell again, then an open and transparent competitive environment will be formed when purchasing, and the seller can get better prices

3. Rece business transaction friction. Managing spending is a challenge for most organizations. However, blockchain enables enterprises to create self-management networks for suppliers and partners, realize contract automation, real-time payment, tracking of goods transportation, and visibility of the whole supply chain. For example, if a company uses refrigerated containers to transport perishable goods, when the container temperature exceeds a certain threshold, the IOT sensor on the truck may call the smart contract on the blockchain. This will cause the corresponding order to be cancelled, and it will also be able to automatically create a new order, so that a second batch of goods can be sent immediately. Trucks with faulty refrigeration equipment can also go to the repair Office for repair

This kind of network can rece transaction errors and information omission by recing or eliminating human-computer interaction. Moreover, by connecting buyers and sellers directly, transactions can become faster. Manage and secure decentralized private records. Its traditional instry practice is to rely on a third party, using firewalls and restricted access to protect their shared information database. And frequent data leakage events show that this approach is not very ideal. A fundamental advantage of blockchain is that each indivial data record or element is encrypted by the key of a blockchain member. Cybercrime may need to obtain each key of each member in order to access all the blockchain data. This is not to say that blockchain can guarantee 100% security of all data, which helps to rece the possibility of exposure of a large number of private records

5. A reasonable application is the record of employees or students. Employers, ecational institutions and even instry certification bodies can add new qualifications, grades or work places when necessary. Imagine giving employees a key to access all their employee records as part of a secure blockchain containing human resources. Indivials can safely share their university transcripts or employment history with other companies or ecational institutions without relying on unreliable and easily falsified faxes. Trace the origin of procts and raw materials. Blockchain can help ensure proct quality and safety by simplifying the tracking and positioning of procts and raw materials in use. For example, if an automobile manufacturer forms a quality centered blockchain including parts suppliers, parts assemblers, quality control suppliers and public management organizations (such as the National Highway Traffic Safety Administration). Then the recall process of defective parts will be faster. It makes sense to think that thousands of people die every year because of defective car parts

6. Verify identity, verify published information and data. Create a better user control mechanism. Nowadays, user information is easy to be manipulated, distributed to third parties, or even sold, so as to create revenue streams for owners of social media platforms, which will never be shared with users of information. Blockchain can disrupt all of these activities. It allows users to control their own information and its exact location. No platform can be accessed without permission. Users can decide who can access their information. They can deal directly with advertisers and third parties according to their choice, rather than like others. Moreover, users can choose to share their information with advertisers on any platform for a fee

to sum up, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method (reference network) for programming and operating data by using intelligent contract composed of automated script code

Application in finance

three major applications of blockchain technology

1. Application of blockchain technology in asset securitization field

< / OL >

in recent years, The domestic asset securitization (ABS) instry is developing rapidly. At the same time, the problems of asset cash flow management need to be improved, the transparency and efficiency of underlying asset supervision need to be improved, the efficiency of asset transaction settlement is low, and the cost of credit enhancement is high are graally exposed. In order to apply blockchain technology in ABS field, participants need to build ABS blockchain alliance, which is composed of asset side, pre ABS investor, SPV (trust), escrow bank, manager, intermediary, ABS investor and exchange. Its core business includes fund transaction reconciliation, transaction file management, data interaction interface, information release and sharing, underlying asset management, intelligent ABS workflow and so on. Blockchain application can at least empower ABS instry in the following five aspects

To improve the cash flow management of ABS< Second, it is concive to penetrating supervision
thirdly, it can improve the settlement efficiency of financial assets< (4) the efficiency and transparency of securities trading will be greatly enhanced
fifthly, it can rece the transfer cost of credit enhancement

2. Application of blockchain technology in insurance instry. However, with the tightening of regulatory policies on medium and short-term survival procts, the business scale of universal insurance has declined significantly. In the aspect of insurance proct design, blockchain is concive to promoting the breakthrough and rapid development of customized insurance categories, such as agricultural insurance and proct quality insurance

quality insurance can endorse the reputation of enterprises and protect the rights and interests of consumers. However, insurance companies need to make a comprehensive evaluation of enterprises and procts to underwrite quality insurance, but these data are often difficult to collect truly and effectively, which restricts the development of quality insurance. The establishment of proct traceability and anti-counterfeiting application platform based on the underlying technology of blockchain can help insurance companies easily trace the information of proct proction, processing, sales, purchase, complaints and other links through the platform, so as to effectively judge the incidence of quality defects of related procts, formulate insurance procts, and promote consumption upgrading and instrial upgrading


in insurance sales, the application of blockchain technology can simplify the sales process, save the sales cost and realize the traceability of insurance sales. From the perspective of insurance companies, when willing policyholders purchase insurance policies through channels, channel providers uniformly send policyholders' information to the blockchain platform. The platform judges whether willing policyholders are in the white list according to the distributed storage information. If they meet the standards, they will accept the purchase request, which saves the tedious process of manual transmission, acceptance, review and feedback. From the perspective of consumers, blockchain technology can realize the traceability of insurance sales behavior and safeguard the legitimate rights and interests of consumers. The insurance sales market has been in chaos, and the phenomenon of false publicity of insurance procts through deception, concealment or incement has been repeatedly prohibited. Blockchain technology can link the key actions of each link of insurance sales, and realize the traceability of the whole process of sales actions, so as to standardize the insurance sales behavior and promote the sustained, healthy and stable development of the instry

in the insurance claim process, the application of blockchain technology can improve the claim efficiency and customer experience. Claim and loss handling process is an important process in insurance market. The complex claim process increases the cost, reces the claim efficiency and affects the customer experience. Smart contract technology can simplify the claim submission process, rece the need for manual review and shorten the processing cycle. At the same time, it is easier to identify suspicious behaviors through the historical claims and asset source records in the distributed ledger
in the field of insurance anti fraud, the application of blockchain technology can effectively prevent the occurrence of insurance fraud. Insurance fraud not only erodes the profits of insurance companies, but also damages the legitimate rights and interests of other insurance consumers. Although every insurance company has made a lot of efforts in anti fraud, the reality is still grim. Blockchain technology can at least help the insurance instry alleviate or even resolve this stubborn disease in the following two aspects. First, establish anti fraud sharing platform to rece fraud and strengthen evaluation through historical claim information; The second is to establish "unique and identifiable identity information" by using reliable data sources and coded business rules, so as to prevent false use of identity

3. The application of blockchain technology in the field of asset custody
in recent years, the global asset custody instry has entered the fast lane of rapid development, and the scale of Custody Assets and main custody procts have maintained rapid growth., However, there is still a certain gap between this scale and the international advanced peers, and there is still a large space for the development of China's asset custody instry

the application of intelligent contract technology in blockchain can effectively solve the operational risk in asset custody business. We can optimize the business process of asset custody from the following aspects: first, we realize the automation of the whole process, encapsulate the business instruction judgment and execution rules into the smart contract, use the smart contract execution and provide risk tips; The second is to improve the process efficiency, the real-time sharing of asset change, transaction details and other information among the asset consignor, manager, trustee and agent, eliminating the process of repeated verification and right confirmation; The third is to ensure the security of the performance and the authenticity of the transaction. By setting the key, the formal information of the participants, the limited visibility of the account information and the verifiability of the transaction are guaranteed; The fourth is to ensure that the information can not be tampered with, and put the compliance verification requirements of the investment plan on the blockchain to ensure that each transaction is completed on the basis of consensus


at present, bitcoin is the most closely related to blockchain. If you want to learn more about bitcoin blockchain, you can follow some new media. For example, Sohu, Baijia, mustard circle and so on. Foreign websites, such as CCN, coindesk, etc., all have huge applications

3. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.

4. Blockchain application will be the first to start in the financial field with high credit cost. The corresponding investment field involves cross-border payment, and the securities issuance and trading system and insurance instry may benefit first. Relevant concept stocks are as follows, for reference only:

5. In terms of application, it is generally believed in the instry that blockchain application will take the lead in the financial field with high credit cost, and the corresponding investment field involves cross-border payment, and the securities issuance and trading system and insurance instry may benefit first. Relevant concept stocks are as follows, for reference only:

Hengbao stock: big data security analysis

Yuanying China: a digital currency crowdfunding company This is the first time.

6. Very bad. The instry is in a mess
blockchain is not easy to do since 18 years ago. The instry is deceptive, professional cut leek. I remember that the blockchain network reported that Li Xiaolai was cutting leeks. Li Xiaolai was going to build a blockchain network, so that their second round of financing had stopped. It was said that they had sold it to a technology company in Guangzhou

7. Blockchain and 5g are known as the fourth information technology revolution, and the blockchain technology is not to be missed by all countries, especially in developed countries. Therefore, the prospect of blockchain technology is considerable, and the application scenarios are rich, mainly in data storage
blockchain technology is favored by various countries, but the reputation of blockchain finance is very poor. Although the reputation is very poor, blockchain finance and blockchain technology are inseparable, so blockchain finance is also essential
for newcomers to enter the coin circle, first of all, understand some principles of bitcoin blockchain finance, what bitcoin is and what its role is for the blockchain, observe the trend of mainstream currencies in the coin circle for a period of time, don't enter the coin circle disorderly, you can see it by people's analysis, but you should have your own analysis. If a new currency appears, you should see their website, White papers, communities, whether there are things to do, etc. don't buy them as soon as you come up. Observe them
in addition, some mainstream currencies in the currency circle are bullish for a long time. You can hold some of them for fixed investment. For example, if you buy EOS at 30 yuan, but it keeps falling, you can enter some more at 25 yuan to rece the average price. Also, don't sell it all at once, because after you sell it, you may not be able to enter the market at such a low price. If you buy high or fall, you will be covered
as for Shanzhai coins, we must go into their communities and communities to see their situation, carefully observe and see the good news they have released
my suggestion is that the mainstream currency should be fixed investment. In the long run, one or two Shanzhai currencies are OK, because it is possible for Shanzhai currencies to take off more quickly when they rise,
for example, one currency I have observed for a long time is TTC, which is a small community, but has been doing things all the time, such as wallets, finance, social networking, and finally based on the token TTC, All are done on the main chain of TTC, and all are serving TTC. So you need to know them better. In a word, we should be cautious. We can take a small part of our own money, but not too much.
