⑴ Ye Mao, founder of Zhifan Technology: On-chain data analysis will be very promising

In recent years, my country has continued to carry out the crackdown on telecommunications network fraud crimes and has achieved important results. With the emergence of emerging technologies such as blockchain and artificial intelligence, fraudsters have found new tools to commit crimes and have begun to use blockchain technology to organize fraud and transfer of stolen money, which has brought new challenges to political and legal work.

Blockchain itself is a neutral technology, but criminals use blockchain virtual currency to commit fraud crimes in order to make illegal profits, which has caused great harm to economic and social development. It is understood that virtual currency has the characteristics of anonymity, global circulation, and difficulty in tracking, which makes it more difficult for the public security organs to handle cases.

As the earliest company in the country to track virtual currencies, "Zhifan Technology" uses technologies such as heterogeneous multi-dimensional data mining, massive data knowledge graphs, and on-chain big data analysis to build on-chain addresses through algorithms. Through the correlation between on-chain and off-chain data and the currency flow tracking method, a complete virtual currency tracking solution has been established, and has achieved remarkable results in the practice of supervision. At present, Zhifan Technology has provided relevant technical services to public security agencies across the country more than 500 times.

Ye Mao, founder of Zhifan Technology, said, “Some criminals take advantage of the anonymity of blockchain to carry out illegal and criminal activities. The tracking service of virtual currency is of great help to public security agencies and regulatory agencies. At the same time, this It is also an important application scenario of blockchain big data and the future development direction.”

Over the years, Zhifan Technology has been at the forefront of researching virtual currency crimes and has accumulated rich experience in blockchain big data. Data resources. Zhifan Technology realizes that in order to effectively combat virtual currency crimes, it is necessary to establish a new governance model that links police and enterprises. On the one hand, we must rely on the case-fighting capabilities of the public security organs to intensify the crackdown on virtual currency crimes; on the other hand, we must comprehensively improve the capabilities and levels of case-handling personnel and accelerate the training of new police talents.

Focusing on this idea, Zhifan Technology took the lead in developing the "Virtual Currency Tracking and Verification Platform" in 2018 to provide tool support for the public security in daily research and judgment of virtual currency cases, and established cooperation with hundreds of public security agencies across the country. . At the same time, relying on the "Zhifan Academy" of the Public Security Intelligence and Big Data Application Research Center, many training lectures related to virtual currency and virtual currency tracking and verification were carried out to help case investigators quickly master the skills of virtual currency tracking and evidence collection.

It is worth mentioning that in order to better solve the verification problem of virtual currency cases, based on big data analysis and mining of blockchain, Zhifan Technology combined its own practical experience to launch a new version of The virtual currency tracking and verification platform "Zhuji" has been significantly upgraded compared to the previous version, and has added a variety of practical functions. It has the characteristics of obtaining the latest on-chain data of virtual currencies in real time and tracking the fund flow of targets..

In addition, because blockchain virtual currency crimes are extremely confusing, it is difficult for ordinary people to identify them. Zhifan Technology exposed the criminal methods related to blockchain and virtual currency on its own official platform, and provided safety reminders to netizens through entertainment and education. At the same time, some safety precaution dramas will be produced to prevent everyone from being fooled.

Ye Mao said, "From the current point of view, regulatory policies will play a crucial role in the development of the industry. We hope to use blockchain big data analysis and other technical means to provide solutions for this type of development." Provide help in supervision, reduce the property losses of the people, and protect the blockchain industry. This is also the original intention of our business."

Ye Mao believes that the inevitable trend of blockchain governance is to start from "code. From "governance" to "governance by law", new money laundering crimes based on virtual currencies pose challenges to supervision. There is an urgent need to arm them with blockchain technology and fully apply blockchain big data to actual combat. This is exactly what "learning from foreigners" means. The best embodiment of "developing skills to control barbarians". (Zhang Fan)

⑵ The application of blockchain CRM technology can be expected in the future

The application of blockchain CRM technology can be expected in the future
Blockchain technology has been recast Customer expectations for data privacy, bringing competitors together, enhanced data analysis, and enhanced customer relationships are features that make it a major disruptor in CRM.
In 2017, the crazy rise of digital currencies attracted a lot of attention. Although most people still have widespread doubts about its actual value, in fact, the application value of the blockchain technology behind digital currency has been generally recognized.
The payment mechanism and communication channels built by the blockchain allow users to conduct direct commercial transactions without third-party intervention. At the same time, the characteristics of the blockchain network itself allow it to support linear, permanent index records, which enables users to conduct global review or reference without any authorization at all.
As blockchain technology is applied to more industries, what impact will it have on CRM? To this end, this article lists the predictions of three experts on blockchain CRM.
Blockchain technology recasts customer expectations for data privacy, brings competitors together, enhances data analysis, and enhances customer relationships. These capabilities make it a major disruptor in CRM.
The technology behind Bitcoin and other cryptocurrencies can be difficult to explain, or get people interested in. Because it involves infrastructure, not new technologies like artificial intelligence. However, experts expect the use of blockchain CRM technology to increase over the next 10 years, predicting that business sectors including healthcare, insurance, utilities, government, supply chain, publishing, and real estate will also find use for the technology. Where to apply.
Blockchain creates a distributed, encrypted ledger that can operate without centralized management and serve as a highly trustworthy record of transactions, digital rights, and sensitive data such as identities and attributes.Letter repository. Transactions can be self-executed through smart contracts, eliminating friction and transferring data value without the involvement of traditional media.
SearchCRM spoke with three experts at this month’s Blockchain Forum. While blockchain CRM technology may still be in its infancy, experts say they see huge potential for widespread application in industry sectors.
Blockchain can solve privacy and data analysis issues
Paul Tatro, co-founder of the Blockchain Training Institute, said that CRM systems will be affected by issues related to data privacy. As consumers are asked to share personal information and risk exposing themselves to hackers, such as the Equifax data breach this fall, they're eager for change. Blockchain can store and encrypt personal data and confirm details without actually sharing them.
He said: "The whole CRM field will soon be linked to what I call 'self-sovereignty', because customers will want to control their information and not have it disseminated freely." With self-sovereignty, you can control your own identity and show what you want to say, not the truth.”
He also mentioned that CRM systems need to adjust the way they handle customer data to satisfy consumers Rising expectations.
Tatro said he also expects the future of blockchain CRM technology to include new opportunities for large-scale data analysis. A networked CRM-based system can provide multiple services (including those of competitors) and provide in-depth insights into customer preferences, opinions and purchasing habits. The quality of insights will improve with scale, and blockchain’s network architecture will eliminate the need for intermediary data managers. Additionally, with such a shared system, developers need to create distributed ledgers with precise access rights so company data can be protected.
Blockchain-based applications may be limited in the short term, but champions can make the case for early investment to ensure organizations can move quickly and create opportunities for them.
“We see companies like IBM and Microsoft already offering blockchain services,” Tatro noted. “Even Intel is pushing SGX chips to optimize transaction processing and speed up consensus on the blockchain. This is something companies need to focus on, just like you had to understand it when the Internet came out.
Tatro said that he established a blockchain training academy to provide blockchain education and certification. Training is delivered online so users can learn at their own pace.
Blockchain Technology Improvement Incentive Program
Lynne Dunbrack is the vice president of IDC Health Insights. She believes that blockchain CRM technology plays an important role in the healthcare field.
“CRM inThe healthcare space is fairly new," she said. "One area where blockchain may impact is customer incentive payment programs aimed at achieving health milestones. "
Healthcare providers often recommend exercise programs, such as walking 10,000 steps a day, through which patients can earn points that can be redeemed for items such as merchandise.
"In short-term goals," she said Once achieved, people lose interest in the exercise program. "Maybe they want to stay healthy during pregnancy, or lose weight before a school reunion or wedding to look good in family photos, but then they fall back into their old habits." ”
The future of blockchain CRM technology may include strengthening patients’ connections to reward programs, enabling monitoring data to be processed in near real-time as frictionless micro-transactions.
“Now they can discover themselves in real time,” Dunbrack said How to move toward established reward goals instead of waiting for a monthly report. “It’s a fun and playful way to help keep customers engaged for the long term. ”
The application of blockchain to CRM technology will improve customer lifecycle management. This is an increasingly important issue in healthcare as the vertical focus shifts from billing and reimbursement to patient-centered health outcomes .
“The whole idea of ​​patients as consumers is relatively new,” she said. “In the past, doctors would refer patients to a specialist or something and the patient would go, but now they’re looking around to see if they can save money elsewhere. “Medical organizations need to capture customer focus and manage the customer lifecycle like other industries.
Blockchain CRM technology changes the way leads are generated
Jacob Hall is the co-founder of Agingo Corp. A search platform using blockchain and machine learning was created to identify the most trustworthy businesses across more than 200 topics. Users of Agingo can discover new companies within their chosen areas of interest as they are listed on Agingo The community has gained trust.
The company will not be able to purchase placement at the top of the Agingo search engine because it is not ad-driven.
“We believe the current ad space is broken,” Hall said. Want to change the way people interact with the brands and people they love. ”
One company will not be able to dominate multiple categories in retail because companies will have to choose their search categories when placing on Agingo.
“The fewer keywords you have, the higher your ranking will be,” Hall said. The higher it is. No targeted marketing. We give users the freedom to express their wishes so they don't have to see the same thing over and over again because someone is tracking them and retargeting them. ”
According to Hall, Agingo’s approach will impact CRM-based lead generation.
“Companies have to advertise to get leads,” he said., purchasing data from unknown sources. But it's not like people providing data lineage for their email addresses. ”
Another co-founder, Kyriakos Skiouris, said that small businesses will be able to effectively attract attention in Agingo by earning trust.
He mentioned: “We like innovation and we like mom-and-pop shops. In traditional search, if you want to open a restaurant and be known, you must be prepared to invest millions in marketing expenses. So when rich people can stick to the top, of course they like the system. That's what we want to correct. ”
Like Tatro, Hall also acknowledged that the future of blockchain CRM technology will be affected by users’ concerns about privacy. Agingo users can store personal data in encrypted wallets and easily decide what information they want to share .
Hall said: "When you see more and more attacks, such as the Equifax breach, people will seek to interact with people they trust. "In other words, blockchain CRM will receive more and more attention in the future.

⑶ Big data and blockchain

This story still has to start with Bitcoin

Bitcoin, the electronic cash system, is both disintermediated (electronic cash between individuals does not require the intervention of a trusted third-party intermediary) and decentralized (maintained by an institution) (both parties to the transaction) Transactions can be completed without establishing a trust relationship)

Hash function: Convert any long string into a fixed-length output (the calculation process cannot be too complicated), as long as the input string occurs With slight changes, the output of the hash function will be completely different.

Blockchain: Divide large things into many blocks for storage. As long as one of the things is tampered with, the data below will be If they are different, they will be discovered

Use blockchain (data structure hash function) to ensure that the ledger cannot be tampered with, use digital signature technology to ensure that only you can use your own account, and use p2p The network and POW consensus mechanism ensure decentralized operation

Blockchain uses a block chain data structure to verify and store data, and uses a distributed node consensus algorithm to generate and update data. A new distributed infrastructure and computer paradigm that uses cryptography to ensure data transmission and access security.

Three elements:

The essence of blockchain is distributed The ledger is a kind of database. The blockchain uses a hash algorithm to ensure that information cannot be tampered with, uses public keys and private keys to identify identities, and collectively maintains a reliable database in a decentralized and disintermediated way.

The difference between big data and blockchain is mainly reflected in the following aspects.

(1) Data volume. Blockchain technology is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The amount of data processed by the blockchain is small and has a meticulous processing method. Big data manages massive amounts of data, which requires breadth and quantity, and the processing methods will be rougher.

(2) Structured and unstructured. Blockchain is a block with a rigorously defined structure. The chain composed of pointers is a typical structured data, while big data needs to process more unstructured data.

(3) Independence and integration. In order to ensure security, the blockchain system's information is relatively independent, while the focus of big data is the integrated analysis of information.

(4) Direct and indirect. Blockchain is a distributed ledger, which is essentially a database, while big data refers to in-depth analysis and mining of data, which is a kind of indirect data.

(5)CAP theory. C (Consistency) means consistency, which means that any read operation can always read the result of the previously completed write operation. That is, in a distributed environment, data at multiple points is consistent. A (Availability) refers to availability, which refers to obtaining data quickly and returning operation results within a certain time. P (Tolerance of Network Partition) is partition tolerance, which means that when a network partition occurs (that is, some nodes in the system cannot communicate with other nodes), the separated system can still operate normally. CAP theory tells us that a distributed system cannot meet the three requirements of consistency, availability, and partition tolerance at the same time. It can only meet two of them at the same time. As the saying goes, "You can't have your cake and eat it too." Big data usually chooses to implement AP, and blockchain chooses to implement CP.

(6) Basic network. The underlying infrastructure of big data is usually a computer cluster, while the infrastructure of the blockchain is usually a P2P network.

(7) Source of value. For big data, data is information, and value needs to be extracted from the data. For blockchain, data is an asset and the inheritance of value.

(8) Calculation mode. In the big data scenario, one thing is assigned to multiple people. For example, in the MapRece computing framework, a large task will be decomposed into many subtasks and assigned to many nodes for calculation at the same time. In the blockchain scenario, multiple people are allowed to do one thing repeatedly. For example, many nodes in the P2P network record a transaction at the same time.

⑷ What is the relationship between blockchain and big data analysis

The relationship between blockchain and big data storage is as follows:

1. Data security: area Blockchain allows data to flow with real confidence
Blockchain, with its trustworthiness, security and non-tamperability, allows more data to be liberated. Let’s use a typical case to illustrate how blockchain promotes the generation of gene sequencing big data. Blockchain sequencing can use private keys to limit access rights, thereby circumventing legal restrictions on individuals' access to genetic data, and utilize distributed computing resources to complete sequencing services at low cost. The security of blockchain makes sequencing an industrialized solution, enabling global-scale sequencing, thus promoting the massive growth of data.
2. Data openness and sharing: Blockchain ensures data privacy
The government holds a large amount of high-density and high-value data, such as medical data, population data, etc. The openness of government data is a general trend and will have an immeasurable impetus to the development of the entire economy and society. However, the main difficulty and challenge in data openness is how to open data while protecting personal privacy. Blockchain-based data desensitization technology can ensure data privacy and provides a solution for data openness under privacy protection. Data desensitization technology mainly uses encryption algorithms such as hashing. For example, the Enigma system based on blockchain technology can calculate data without accessing the original data, which can protect the privacy of data and eliminate information security issues in data sharing. For example, company employees can safely open access to their salary information and jointly calculate the average salary within the group. Each participant is informed of his relative position within the group but not of the compensation of other members.

3. Data storage: Blockchain is an immutable, full-historical, and strongly endorsed database storage technology. Blockchain technology is shared by all nodes in the network. Participating in calculations and mutually verifying the authenticity of their information to reach a consensus across the entire network, it can be said that blockchain technology is a specific database technology. So far, our big data is still in a very basic stage. Trusted blockchain data based on the consensus of the entire network is non-tamperable and full of history, which also enables the quality of the data to gain unprecedented strong trust endorsement. It also brings the development of database into a new era.
4. Data analysis: Blockchain ensures data security
Data analysis is the core of realizing data value. When conducting data analysis, how to effectively protect personal privacy and prevent core data leakage has become the primary consideration. For example, with the popularization of fingerprint data analysis applications and genetic data detection and analysis methods, more and more people are worried that once personal health data is leaked, it may lead to serious consequences. Blockchain technology can prevent such situations through multi-signature private keys, encryption technology, and secure multi-party computing technology. When the data is hashed and placed on the blockchain, digital signature technology is used to allow only authorized people to access the data. The private key ensures data privacy and can be shared with authorized research institutions. Data is stored uniformly on the decentralized blockchain, and data analysis can be performed without accessing the original data.The analysis can not only protect the privacy of data, but also safely provide it to global scientific research institutions and doctors for sharing. As a basic health database for all mankind, it will bring great convenience to solve sudden and difficult diseases in the future.
5. Data circulation: Blockchain protects data-related rights and interests
For valuable data assets of individuals or institutions, blockchain can be used to register them, and transaction records are recognized and transparent by the entire network. , traceable, clarifying the source, ownership, use rights and circulation path of big data assets, which is of great value to data asset transactions.
On the one hand, blockchain can eliminate the threat of intermediaries copying data and help establish a trustworthy data asset trading environment. Data Chunxin is a very special commodity, which is essentially different from ordinary commodities. It mainly has characteristics such as unclear ownership and "it is owned after seeing it and copying it". This also determines that the transaction method using traditional commodity intermediaries cannot satisfy the data requirements. sharing, exchanging and trading. Because the intermediary center has the conditions and ability to copy and save all the passing Pazhoulun data, this is extremely unfair to the data producers. This threat cannot be eliminated by relying on promises alone, and the existence of this threat has also become a huge obstacle to the flow of data. Based on decentralized blockchain, it can eliminate the threat of data copying by intermediary centers and protect the legitimate rights and interests of data owners.
On the other hand, blockchain provides a traceable path and can effectively solve the problem of data verification. The blockchain jointly participates in the calculation and recording of data through multiple nodes participating in calculations in the network, and mutually verifies the validity of their information. It can not only prevent information counterfeiting, but also provide a traceable path. By stringing together the transaction information of each block, a complete list of transaction details is formed. The ins and outs of each transaction are very clear and transparent. In addition, when people have questions about the "value" of a certain block, they can easily review historical transaction records to determine whether the value is correct, and identify whether the value has been tampered with or recorded incorrectly.
Everything is guaranteed on the blockchain, and big data will naturally become more active.
The tokens of the crowdfunding projects on the Biying China platform are all developed based on blockchain technology, and relevant information will be recorded on the blockchain.

⑸ Analysis of basic issues that need to be understood for the operation of blockchain

Blockchain is a shared distributed database technology. Although the one-sentence introduction to blockchain is worded differently in different reports, the following four technical features are consistent.
1. Decentralized: The left side of Figure 1 describes the centralized characteristics of today’s financial system, and the right side describes the emerging decentralized financial system, which has no intermediaries and all nodes. Rights and obligations are equal. If any node stops working, it will not affect the overall operation of the system;
2. Trustless: All nodes in the system can conduct transactions without trust, because the database and the entire system are The operation is open and transparent, and the systemWithin the rules and time range of the system, nodes cannot deceive each other;
3. Collectively Maintain: The system is jointly maintained by all nodes with maintenance functions, and everyone in the system participates in the maintenance work. ;
4. Reliable Database: Each node in the system has the latest complete database copy. Modifying the database of a single node is invalid because the system will automatically compare and consider the same data record that appears the most times. is true.
The blockchains of projects such as Bitcoin, Ethereum, and DECENT all have these characteristics.
