① Are there any easy-to-understand books or articles about blockchain that you would like to recommend?

Blockchain and blockchain technology have been widely accepted and used by people. , but I have always had little knowledge about blockchain and blockchain technology, and I am even more confused about the working principle and operation method of blockchain. Maybe you have read a lot of related reports, and there are a lot of professional terms and jargon, but you still don’t have a clear understanding of it. Here Bit Window will explain it to you in a popular way.
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.
This is a professional summary that we usually see in reports, but what is the specific form?
First of all, no matter how big a system or how small a website is, there is usually a database behind it. So who will maintain this database? Under normal circumstances, whoever is responsible for operating the network or system will maintain it.
If it is a WeChat database, it must be maintained by Tencent’s team, and Taobao’s database is maintained by Alibaba’s team. Everyone must think that this approach is natural, but this is not the case with blockchain technology.
Secondly, blockchain technology is also called distributed ledger technology. That is, if we imagine the database as a ledger: for example, Alipay is a typical ledger, and any change in data is an accounting type. We can think of database maintenance as a very simple accounting method.
The same is true in the world of blockchain. Everyone in the blockchain system has the opportunity to participate in accounting. The system will select the person who has the fastest and best accounting during this period, maybe within ten seconds, or ten minutes. This person will do the accounting, and he will record the changes in the database and the ledger during this period. Recorded in a block.
We can imagine this block as a page. After the system confirms that the record is correct, it will link the data fingerprint of the past ledger to this piece of paper, and then send this piece of paper to everyone else in the entire system. . Then the cycle starts over and the system looks for the next person who can do the accounting quickly and well, and everyone else in the system gets a copy of the entire ledger.

Finally, since everyone (computer) has exactly the same ledger, and everyone (computer) has completely equal rights, there will be no loss of contact or downtime due to a single person (computer). And cause the entire system to collapse.
Since there are exactly the same ledgers, it means that all data is open and transparent, and everyone can see the digital changes in each account. Its very interesting feature is that the data in it cannot be tampered with. Because the system will automatically compare, it will consider the account books with the largest number of the same number as the real account books, and the small number of account books with different numbers as others are false account books.
In this case, it makes no sense for anyone to tamper with their own ledger, because unless you can tamper with most of the nodes in the entire system. If the entire systemIt may be easy to do with only a few nodes, but if there are tens of thousands or hundreds of thousands and they are distributed in any corner of the Internet, unless someone can control most of the computers in the world, it is unlikely to tamper with such Large blockchain.
I wonder if I can understand this simple explanation?

② [Hall of Fame] Founder of Blockchain Pencil (ChainB) - Prince Baozou Gong

< p>Gong Ming, also known as "Prince Gong", is the founder of ICO AGE (once the largest ICO platform in China) and Blockchain Pencil (the largest Chinese blockchain media). Since 2012, he has been committed to promoting the development of digital currency and blockchain industries. He has translated and written a large number of relevant materials and blockchain white papers, and participated in "Blockchain Society", "Blockchain - New Economic Blueprint", "Digital Currency" and many other works.

​

Prince Gong of Baozou·Weibo ID

Speaking of Prince Gong of Baozou, people outside the blockchain circle may be unfamiliar, but This title is extraordinary within the circle.

The first time I met Prince Baozou Gong was at the Gravity Zone event in Chengdu. Many blockchain “believers” came for Baozou Gong that day.

Initially, Prince Baozou Gong was just a Weibo ID.

Initial research on digital currency

Just after he was released from prison in 2010, he plunged into the field of digital currency research. With a salary of 1,200 yuan, he silently predicted The trend of digital currency.

In 2012, the transfer payment method was still very traditional. The cumbersome procedures and extremely inefficient transfer process often made Baozou miserable. “After reading the information on Bitcoin at the time, I felt that this could be solved. My past doubts."

Different from most laymen, Bao Bao, a mathematics major, has not only done program development for more than ten years, but also has experience in finance, so he quickly digested the Bitcoin currency and even the logic of blockchain technology. When he transferred the Bitcoins from his wallet to a friend for the first time, Baozhua was particularly excited. "Transferring money is so convenient. It feels like sending an email for the first time. This is the future!"

Bitcoin has opened the door to a new world for the wild, so he is very happy to do some popular science work. "At that time, there were more technical discussions abroad, and I really wanted to spread these things back to China."

Translation & Book Writing

At that time, he translated a large amount of foreign information and reports about Bitcoin on Weibo.

He has translated and written a large number of relevant materials andBlockchain white paper, co-author of "Blockchain Society", "Blockchain - New Economic Blueprint", "Digital Currency" and many other works.

Gradually, everyone became accustomed to calling Gong Ming "Prince Baozou Gong", and "Prince Baozou Gong" has become an influential figure in the blockchain circle.

Blockchain Pencil (ChainB)

Prince Gong translated many articles on blockchain technology, and later created blockchain media: Blockchain Pencil. “I always believe that technology is the most important, so the Blockchain Pencil only introduces technology and tells you what is truly valuable. As for the quality of blockchain applications, we will give you various overseas materials for reference. ”

Blockchain Pencil (website domain name ChainB.com) is an authoritative new media that provides the latest and most comprehensive information reports on the global blockchain industry.

The website publishes authoritative, comprehensive and professional blockchain information in real time 24 hours a day, 7 hours a day, including blockchain-related industry trends, company news, events and conferences, etc. The content covers the block chain Chain companies, related venture capital opportunities, digital currency and digital asset-related news and other news.

Participate in the EOS super node election

At an event, Prince Gong Baozou mainly introduced two blockchain projects in which he participated: the decentralized exchange CYBEX and blockchain incubator LongHash.

He said that EOS.CYBEX will develop the first test chain of EOS and provide EOS developers with a complete testing environment and tools for free. Its LongHash incubator can provide free support to outstanding EOS developers around the world. At the same time, taking this opportunity, Baozou officially announced its participation in the EOS super node election.

Why did you choose to work on CYBEX and LongHash? Baozang also has its own considerations: “What we hope to do is a platform that can provide everyone with complete basic services. The biggest starting point for doing these projects is to hope that the industry will be healthy. Development."

With the participation of candidates such as Laomao, Coin Capital, and Gravity Zone, the competition for EOS super nodes is becoming increasingly fierce. Baozou believes in BM's technical strength, which is why he has been paying attention to BTS An important reason for development is that what CYBEX wants to do on EOS is similar to BitShares.

For these reasons, it is expected that Baozou issued "CYBEX will bring together its deep development experience, market operation experience and rich industry resources to empower the EOS community."

③ Can you recommend any books on blockchain?

There are more and more books in the field of blockchain, and many of themThe quality is actually not high. I recommend two better books that I have actually read and summarized.

---

A book is "Book Blockchain".

This book is characterized by using interesting and vivid comics to express some principles and applications of blockchain.

This book is especially suitable for newcomers who have just come into contact with blockchain, because the principles in it are analyzed using more real-life cases, which is relatively easy to understand and involves blockchain. Technical knowledge is relatively low.

And this book is not thick, so you can finish it quickly. After all, everyone is very busy at work now. If you read a very thick book, it is indeed difficult to read. This book happens to be more It is thin and light and can easily cultivate your interest in learning knowledge in the blockchain field.

④ If you have not read these 8 books, you dare not say that you are an Internet financial person

p>

As an important part of society, finance has always been changed by technology, and this is also true in the Internet era. From the birth of Yu'e Bao in 2013, to the rise of P2P in 2014, to crowdfunding, mobile payments, and today's sharing economy and cash loans, Internet finance has grown from scratch, from small to large, and from chaos to standardization in 5 years. Every step of the journey, every step of the great waves, is recorded by the times, predicted in advance or recorded at all times by those who are interested.

Due to limited vision, this book list was selected based on a small range of readings. Of course, everyone can choose according to their own fields and interests. It is for reference only and you can choose freely!

1. "Zero Marginal Cost Society"

Written by Jeremy Rifkin, CITIC Publishing House, 2014

This book demonstrates synergy A new shared economic picture has allowed Internet finance to "take root".

Finance cannot exist without the real economy, and the capitalist market economic system we are familiar with is undergoing earth-shaking changes. People's future production and lifestyle will be completely different. The traditional financial system has become It’s out of time, so we need Internet finance.

If you want to know the meaning and mission of Internet finance, then read this book and combine financial history and economic history. I believe you will suddenly understand.

2. "Internet Finance: The Coming New Financial Era"

Written by Yao Wenping, CITIC Publishing House, 2014

Yao Wenping currently serves as Debon Chairman of Securities Co., Ltd. and Chairman of Debon Fund Management Co., Ltd.

This book comprehensively explainsIt describes the 9 hot areas of Internet finance from Internet finance, Internet insurance, Internet financing, Internet sales platform, Internet securities, Internet financial management and Internet finance. It can not only fully understand how Internet finance is applied in financing, financial management, transaction, payment , marketing and other subdivided financial fields, and can have a clear understanding of the future picture of Internet finance.

3. "Payment War"

Translator: Xu Bin Wang Xiao

Date of release: January 2015

This book is like a novel, but it is a true story. It tells the entrepreneurial story of the PayPal online payment website and how the famous "PayPal Gang" was formed. Whether in China or the United States, the rise of Internet finance almost always starts with payment. Through this book, you can understand the growth process of an excellent Internet finance company from 0 to 1, which will also give you a more intuitive understanding of the Internet finance industry. How PayPal faced regulation, how it responded to the suppression of counterfeit products and powerful platforms, how it clarified its business model and eliminated internal differences, and the slogan of “subverting the global financial system” it proposed at the beginning of its business. Do these scenes look familiar? It should be said that this is still a crazy and magical era of Internet finance. For entrepreneurs in it, what they have to do is not forget their original intentions.

4. "Currency Revolution: Virtual Currency Changing the Future of the Economy"

Translator: Shu Yu

Date of listing: May 2015< br />
Virtual currency has now penetrated into every corner of the world. From gold coins in Diablo 3 to Facebook points to frequent flyer miles, there are many forms of virtual currency. The virtual financial world is more integrated with the real world than ever before. People began to speculate on whether there is a possibility in the future that virtual currencies will eventually replace real currencies such as US dollars and euros issued by governments.

5. "Bitcoin"

Li Jun, Chang Chai et al. CITIC Publishing House, January 2014

If you have any concerns about digital currency If you have doubts and think that Bitcoin is just a tool for speculation, I suggest you read this book. What kills people is not ignorance but arrogance. Because of arrogance, they reject new things without exploring their principles. The book "Bitcoin" is veryIt clearly sorts out the origin, principles and development trends of Bitcoin. Although some chapters are obscure and difficult to understand, it is still relatively easy to read on the whole, and it will definitely open your mind.

Combined with Hayek's "Denationalization of Currency", you will realize that Bitcoin is definitely a revolutionary product. Maybe it will fail, but you must not ignore it. . Again, there is a price to pay for arrogance, whether it is for a country, a company or an individual.

6. "Internet Finance in Jiangnan"

Chen Yu (Jiangnan Angry Youth), Oriental Publishing House, 2014

This story of Jiangnan Angry Youth This book should be the most down-to-earth book on Internet finance, which is inseparable from the fact that Jiangnan’s angry youth have been engaged in financial practice for a long time. Therefore, when he talks about supervision, risk control, assets, and business models, he hits the nail on the head and points directly to the problem.

Of course, the fundamental force that determines the future of Internet finance is technological innovation. Therefore, although the development of Internet finance must follow financial laws, it should not be limited to the logic of traditional finance. This is why this book is worthy of discussion. place. But no matter what, if you want to fully understand the development trajectory and practical problems of China's Internet finance, this is a good book that cannot be bypassed.

7. "Blockchain: A New Economic Blueprint and Introduction"

Melanie Swann, New Star Publishing House, December 2015

Blockchain technology is known to originate from Bitcoin. The issuance and withdrawal of Bitcoin is not based on some central authority, but is based on a collaborative consensus agreement among network users. Bitcoin is a great experiment. Regardless of its success or failure, the blockchain technology behind it has attracted more and more attention and has become more widely used.

This book systematically introduces blockchain technology and the new economic blueprint extended by this technology. Remember, the decisive force that changes the world is technology! As the book says: A bank credit building marked by steel and concrete is being replaced by blockchain credit where data is the soil.

8. "Sharing Economy: Reconstructing New Business Models for the Future"

Written by Chase, translated by Wang Rui, Zhejiang People's Publishing House, September 2015

/> The sharing economy is not a hyped concept, it represents a real new economic model. Since it appearedThe sharing economy model and the Internet's transformation of the economic world have become more down-to-earth. The sharing economy can indeed reshape the future, and Internet finance can only have lasting vitality based on the sharing economy. We are familiar with companies that adopt the sharing economy model, whether it is Didi Taxi, Airbnb, Dingxing, or even Taobao. It is difficult to imagine how they would operate without mobile payment. Especially with the development of the sharing economy, the credit system of society will be reshaped, which is the foundation of Internet finance. In fact, Bitcoin can also be understood as a sharing economic model, which is discussed in a special chapter in this book. In short, if you want to understand Internet finance, you must first understand the model, trend and significance of the sharing economy.

The financial industry is one of the industries with the highest average academic qualifications. If you take advantage of the Internet, if you don’t study for a day, you may be eliminated. It’s the weekend again, let’s read two more books~

What books have you guys read? Are there any other good books you would recommend? Welcome to add in the message area.

⑤ What is the development process of blockchain applications?

The development process of blockchain can be divided into three stages. Melanie Swann, founder of the Blockchain Science Institute, in her book "Blockchain: A New Economic Blueprint and Introduction", divides the application development of blockchain into three stages: Blockchain Chains 1.0, 2.0 and 3.0.

1. Blockchain 1.0 Cryptocurrency Era (2008-2013)

In 2008, Satoshi Nakamoto first proposed the concepts of Bitcoin and blockchain. In January 2009, the first blockchain was launched. At this stage, people are paying more attention to cryptocurrency transactions, and blockchain is only the underlying technology, acting as a "public ledger".

2. Blockchain 2.0 Smart Contract Era (2014-2017)

In 2014, "Blockchain 2.0" became synonymous with decentralized blockchain databases. At this stage, people mainly focus on the application of the platform. Anyone can upload and execute smart contracts on the blockchain, and will automatically receive rewards after execution. Since this transaction process does not require any intermediary, people's privacy is greatly protected.

3. Blockchain 3.0 Large-Scale Application Era (2018-)

At this stage, people began to build a completely decentralized data network. Blockchain technology Applications are no longer limited to the economic field, but have expanded to art, law, real estate, hospitals, human resources and other fields.

⑥ What book to read to get started with blockchain

"Dahua Blockchain"It is a book published by Tsinghua University Press in September 2019. The author is Zhang Yingping. This book is a blockchain book that comprehensively explains Bitcoin, Ethereum, Hyperledger, and EOS. It is a blockchain development guide that covers basic engineering skills, development languages, and smart contract development. It also covers technology, projects, and careers. A blockchain engineer's guide to development planning.

"Dahua Blockchain"

"Dahua Blockchain" is a book that pays equal attention to theory and practice, is easy to understand and yet professional. Blockchain books. The blockchain technology guide (the first three chapters) mainly explains blockchain concepts, blockchain applications and mainstream blockchain technologies such as Bitcoin, Ethereum, Hyperledger, and EOS. Every reader can fully understand it through learning Implementation principles of mainstream blockchain technology and understand the future development trends of blockchain. The practical development part (the last two chapters) starts with basic blockchain skills, simulates the development of real blockchain projects, and explains in detail the design, development and deployment of smart contracts and DAPPs. Through learning, every reader can master blockchain development. .

⑦ Thirteen books to understand blockchain

​​Blockchain has become a hot word of concern in all walks of life, and is especially important for marketing, communication, and advertising. But at present, many people do not really understand the meaning of blockchain, and most people have only a partial understanding and hearsay.

Teacher BO suggested that everyone should study hard, understand this concept, and then share it in the industry. It will be of great benefit to individuals and the industry. Stop gossiping and start reading. Which books are worth reading?

Book title : Blockchain

Author: (American) Melanie Swann

Douban score: 6.1

Publisher: Xinxing Publishing House

Publication year: 2016-1-1

Content introduction:

This book introduces the current development status and future technology derivative directions of blockchain-related technologies in a panoramic manner Looking ahead, the author believes that blockchain technology may be the biggest technological revolution since the invention of the Internet. The book discusses three different structural levels: Blockchain 1.0, 2.0 and 3.0 from the perspective of the beginning of the integration of Bitcoin's conceptual model and blockchain technology. First, the basic definitions and concepts of Bitcoin and blockchain technology are introduced, as well as the currency and payment system as the core of blockchain 1.0 applications. Secondly, Blockchain 2.0 will go beyond currency and develop into currency markets and financial applications, similar to contracts. Then, Blockchain 3.0 is an application beyond currency, finance and markets. At this broad level, there will be some forensic applications, such as blockchain management, which can be improved bySome service systems, such as WikiLeaks, ICANN and DNS, have developed into distributed clouds, thus staying away from some unfair jurisdictions and at the same time contributing to the protection of intellectual property and the verification and authentication of digital identities. But the idea of ​​blockchain is more than that; it is a new organizational paradigm for discovering, valuing assets, transferring all quantities of anything, and coordinating all human activities on a much larger scale than was possible before, and we may be in the midst of The dawn of this revolution.

About the author:

⑨Do you have any recommendations for good blockchain books?

《 "New Economic Blueprint and Introduction"

Published: 2016

Recommendation: This book is mainly for programmers. Combined with API programming, it tells you the principles and usage of cryptocurrency, and how to develop related software. For non-programmer readers, the first few chapters of this book are still applicable as an in-depth introduction to Bitcoin.

⑩ How to define blockchain and what are the application scenarios of blockchain?

Nowadays, many people think that blockchain is a universal technology that can do anything, which is somewhat different. Blockchain technology is a myth!
Regarding the definition of blockchain technology, American scholar Melanie Swann defined blockchain technology as an open, transparent and decentralized technology in her book "Blockchain: A New Economic Blueprint and Introduction" database.

Definition of Blockchain: Narrow VS Broad

As for the application scenarios of blockchain technology, it is natural to combine the differences between blockchain and other technologies. In terms of system characteristics.

Blockchain technology features include:

Blockchain is a global A database storage system that can operate in various places and coordinately, which is different from traditional dataLibrary operation - read and write permissions are in the hands of a company or a centralized authority (centralized characteristics). Blockchain believes that anyone with the ability to set up a server can participate. Nuggets from all over the world have deployed their own servers locally and connected to the blockchain network to become a node in this distributed database storage system; once joined, the node enjoys exactly the same rights as all other nodes and obligations (decentralized, distributed characteristics).

At the same time, people who provide services on the blockchain can perform read and write operations on any node in the system. In the end, all nodes around the world will complete the process again and again according to a certain mechanism. Synchronize in sequence to achieve complete consistency of data in all nodes in the blockchain network.

At the beginning of this year, the term blockchain began to enter everyone’s lives. From national leaders to aunts who dance square dances, everyone knows this term. This term is widely known by Bit Brought by coins.

As we all know, the first few dozen bitcoins could only be exchanged for one pizza. At its peak, it was more than 20,000 US dollars each, which has skyrocketed by more than a thousand times, which has also benefited a large number of wealthy people. Currently, there are blockchain The virtual currency generated by technology is gradually entering into everyone's life, and many people have joined the ranks of currency speculation. I often hear people say that if you buy the right currency a hundred times, a bicycle will become a sports car, and one coin will turn a young model. You can imagine how many of them are involved. Attractive.

Since 2008, various games applying blockchain technology have also become popular, such as development games (Network Letts Dog, 360 Block Cat), mining games (NetEase Planet, Virtual Earth, Gongxinbao), these are attracting everyone to join in the name of blockchain, and of course there are some that are really reliable, which requires everyone to identify them carefully.

Blockchain is a distributed ledger (database) that connects data blocks in an orderly manner and cryptographically ensures that it cannot be tampered with or forged. technology. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.

Digital currency

After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.

Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also releasedpublished a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.

my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.

Financial asset transaction settlement

Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

Digital Government Affairs

Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "instant reimbursement after invoicing" - in seconds Level invoicing and minute-level reimbursement accounting significantly reduce tax collection and management costs, and effectively solve data tampering, over-reporting of one ticket, and theft.Tax evasion and other issues. Poverty alleviation is another practical application of blockchain technology. Utilize the characteristics of openness, transparency, traceability, and non-tampering of blockchain technology to achieve transparent use, precise investment, and efficient management of poverty alleviation funds.

Evidence-based anti-counterfeiting

Blockchain can prove the existence of a file or digital content at a specific time through hash timestamps, and it is open, non-tamperable, and traceable. It provides perfect solutions for judicial forensics, identity certification, property rights protection, anti-counterfeiting and traceability, etc. In the field of intellectual property, the digital signature of blockchain technology and on-chain certificates can confirm the rights of text, pictures, audio and video, etc., and create and execute transactions through smart contracts, allowing creators to regain pricing power and preserve data formation in real time. The evidence chain covers the three major scenarios of rights confirmation, transaction and rights protection. In the field of anti-counterfeiting and traceability, blockchain technology can be widely used in various fields such as food and medicine, agricultural products, alcohol, and luxury goods through supply chain tracking.

Data services

Blockchain technology will greatly optimize existing big data applications and play a huge role in data circulation and sharing. In the future, the Internet, artificial intelligence, and the Internet of Things will generate massive amounts of data. The existing centralized data storage (computing model) will face huge challenges. Edge storage (computing) based on blockchain technology is expected to become a future solution. Furthermore, the non-tampering and traceability mechanism of blockchain ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.

The three words "blockchain" were completely ignited during the Spring Festival that just passed. The limelight overshadowed everything. Some people said that this was the arrival of a new era. The past It has become a classic, and some people say that it is all hype and is ultimately a bubble.

In fact, blockchain technology is not a new concept. It has been applied to many industries, such as electronic signatures, as early as the past two years. Recently, the third-party electronic signature platform eShanbao revealed the latest progress of blockchain applications to NewSeed.

Currently, blockchain technology is mainly used in e-signature products for certificate deposit and certificate issuance. Application scenarios include copyright protection, online signatureAppointment, web page evidence collection, phone recording, email evidence storage, etc.

Take the rights protection of online works as an example. Since online rights protection generally adopts the method of collecting evidence after the fact, real-time confirmation of rights is not carried out in the process of evidence generation, so the entire confirmation process is difficult. The copyright process is time-consuming, difficult and costly to obtain evidence, and extremely difficult to prove and trace the source. It cannot meet the characteristics of rapid dissemination and large quantity of online works.

eShanbao's new intellectual property protection solution based on timestamp + blockchain starts from the user's real-name authentication and solidifies the information generated in the process in real time. Electronic data, and through the time source service synchronized with the National Time Service Center, online works are stamped with legally valid timestamps to prove that electronic files have not been tampered with in a certain period of time. Blockchain technology can establish point-to-point trust in the network, ensuring that all blockchain nodes can record complete copyright confirmation and transaction records, and can trace their origins, truly realizing anti-repudiation and anti-tampering, and realizing a kind of distribution. trust infrastructure.

Founder and CEO Jin Hongzhou believes that the application of decentralized blockchain technology has greatly improved the efficiency of data storage and certification, and The credibility of the identity of the parties reduces the cost of trust, but it cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.

Next, e-Shanbao will also focus on building a smart contract platform based on blockchain technology. Jin Hongzhou said that data storage, Issuing certificates is only a relatively superficial application based on blockchain technology. It is the first step to implement blockchain technology, and the realization of real smart contracts is the second step. "Smart contracts cannot simply be understood as electronic contracts. They refer to a process, from the conclusion of the contract to the confirmation to the final execution." Jin Hongzhou explained.

From a technical perspective, blockchain is not a brand-new technology, but a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and smart contracts. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.

Due to its advantages such as "decentralization", "distributed data storage", "traceability", "anti-tampering", and "openness and transparency", blockchain technology can effectively solve data problems. By establishing a trustworthy data management environment, we can prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote the efficient sharing and application of data. In the process of practice and exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions, and continues to empower public resource transactions.Management services.

Facilitate transaction data sharing and transaction witnessing

Facilitate transaction data Share

Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. It is difficult to verify the off-site performance provided by the bidders during the bid evaluation process. It is difficult to troubleshoot the same person repeatedly serving as project manager. Issues such as low cost of breach of trust. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.

The distributed ledger feature based on the blockchain can effectively ensure the real-time or quasi-real-time sharing of data, and can reduce the repeated entry of subject information; the use of blockchain information that cannot be tampered with can ensure the data circulation process on the chain. The authenticity of the bidders in the regional alliance is directly obtained from the on-chain data, making it impossible to hide the fake performance. At the same time, the sharing of bidding behavior data through the blockchain provides a data basis for the development of "joint punishment of dishonest enterprises".

Blockchain-based transaction witness

"Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" ( The State Office Letter [2019] No. 41) pointed out the need to optimize services such as witnessing, venues, information, files, and expert extraction. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.

Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the data generated through time stamp technology, summary algorithm, and electronic signature technology. Time, content, data source. According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain. Save via a distributed file storage service. When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction. Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.

Promote the rationalization of electronic guarantee rates

Promote financial services and corporate financing for bidding companies

Promote the rationalization of electronic guarantee rates

At present, electronic bidding deposit guarantee guarantees have a certain application in the bidding field.The specific application solves the problem of capital occupation in bidding deposits for bidding companies. However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.

At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .

Promote financial services for bidding companies

The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.

Solving the financing problems of successful bidders

Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements for accurate financial statements and sustained profitability, but most small and medium-sized enterprises cannot provide these "proofs" at all. Difficulty and expensive financing have become problems faced by many small and medium-sized enterprises in bidding activities. Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools. With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder. On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.

Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data trustworthiness but also reduces the risk of corruption. Got itThe entire system relies on a centralized authority.

Through further analysis, we found that credit sales are currently prevalent among domestic enterprises, and the upstream suppliers of the winning bidder have a large funding gap. The credit of the bidder can only be passed to the winning bidder (the winning contract cannot be split or transferred), and the upstream suppliers Business owners are unable to obtain high-quality loans from financial institutions. If the winning contract is converted into a "pass" on the chain, the "pass" can be split, and the winning bidder holding the "pass" can pay part or all of the voucher to the upstream supplier, making it discountable and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.

Regarding blockchain, we can imagine a decentralized management model and technical processing method.

Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.

So, you and your family discuss it together and simply use voting to solve the problem.

Then this way of voting to solve problems can be called the most elementary blockchain.

Decentralization solves problems.

What application scenarios can blockchain have?

In fact, many of our families and many organizations use blockchain management forms every day

However, this kind of blockchain application for organizational relationships cannot produce Economic Value.

What are the economic applications of blockchain?

The first type is used for tax deposit certificates, bank transfers, etc.

Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time

The second type is applied to enterprise operation and management

Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.

Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.

The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.

Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.

In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.

At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.

Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.

The most popular application industry at present is the financial industry.

An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since traffic fraud in digital advertising causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud

In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries, creating a new ecosystem based on technological trust. Mode

What is blockchain

If you explain blockchain in non-technical terms, blockchain is a place where data is stored. However, the data stored in the blockchain is safe and reliable and does not need to be managed by anyone. Therefore, in the Internet, a place where data and information are exploding, having such a place will be like a magical treasure land.

What can the blockchain do?

If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:

Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.

If there are any deficiencies, you are welcome to comment and correct me.

In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.

Both parties involved in the transaction do not need toTo know who the other party is, you don’t need a third party for trust endorsement. You only need to trust a common algorithm to establish mutual trust and conduct direct transactions.

Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.

In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.

1. Cloud storage

This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?

Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.

2. Medical aspects

Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
