『一』Do 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.
A detailed explanation of each application is as follows:
1. Digital Currency
At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency. Digital currency has established digital currency transaction credit backed by sovereign currency. The greater the transaction volume and the more frequent transactions, the stronger the digital currency transaction credit foundation. Once the blockchain credit system is implemented globally, digital currency will become a gold-like global payment credit.
2. Payment and settlement
At this stage, settlement and payment of commercial trade transactions all rely on banks. This traditional method of conducting transactions through intermediaries requires the account opening bank, counterparty bank, central bank, and overseas bank. In this process, each institution has its own accounting system, needs to establish an agency relationship with each other, and needs a credit line; each transaction needs to be recorded in its own bank, and must also be cleared and reconciled with the counterparty, resulting in Transactions are slow and costly. Compared with the traditional payment system, blockchain payment is carried out directly by both parties to the transaction without involving intermediaries. Even if part of the network is paralyzed, it will not affect the operation of the entire system. If a universal distributed inter-bank financial transaction protocol is built based on blockchain technology to provide users with cross-border, real-time payment and clearing services in any currency, cross-border payments will become convenient and low-cost.
Take cross-border exchange as an example. If I open an account in a small bank in my country and transfer money to another small bank abroad, the transfer process under the traditional SWIFT system requires the following steps: First, I send money to the small bank to which I belong. Banks submit applications; second, small banks submit applications to large banks in the same country that have signed exchange terms; third, large banks wire transfers to overseas cooperative banks; fourth, cooperative banks remit funds to small overseas banks. Currently, the process takes anywhere from 10 minutes to two days, depending on the country. If you use blockchain-based settlement technology and place an order at a market maker while remitting RMB, a trading bank participating in the system in the world will receive the order, and the two parties will shake hands to complete the exchange. The average payment confirmation speed will be in a few seconds. within seconds.
3. Digital bills
Digital bills are a brand-new bill presentation form developed by combining blockchain technology with bill attributes, regulations, and markets. It is completely consistent with the technical architecture of the existing electronic bill system. different. The core advantages of digital bills are mainly reflected in: First, the disintermediation of the value transfer of bills. In traditional bill transactions, bill intermediaries often use information differences to match. After point-to-point transactions are realized with the help of blockchain, bill intermediaries will lose their intermediary functions and reposition their identities. The second is to effectively prevent bill market risks. Due to the blockchain's non-tamperable timestamps and the fact that it is open to the entire network, once a transaction is made, there will be no default, thus avoiding the problems of "one vote selling more" for paper tickets and out-of-sync payment and endorsement of electronic tickets. Third, the system construction and data storage do not require a central server, eliminating the development costs of central applications and access systems, reducing the maintenance and optimization costs of the system under the traditional model, and reducing the risks caused by system centralization. The fourth is to standardize market order and reduce regulatory costs. The non-tamperable timestamp formed by the continuous connection of blockchain data greatly reduces the cost of regulatory review. The completely transparent data management system provides a trustworthy traceability path, and shared constraints can be established in the chain for regulatory rules through programming. code to achieve full coverage and hard control of regulatory policies.
4. Proof of Rights and Interests
Every node participating in the maintenance of the blockchain can obtain a complete data record. Using the characteristics of the blockchain's reliability and collective maintenance, the rights of the owners of rights and interests can be confirmed. For the need to store permanent records, blockchain is an ideal solution for scenarios such as land ownership and equity transactions. Among them, proof of equity is the field with the most applications currently. Equity owners can prove their ownership of the equity with their private keys. When the equity is transferred, it is transferred to the next owner through the blockchain system. The property rights are clear and the records are clear. The entire process does not require the involvement of a third party.
During a keynote address at the 2015 European Financial Journalism Awards for Excellence in Trading Technology in London, Nasdaq CEO Bob Greifeld announced that the exchange intends to use blockchain technology to manage its proxy voting system. Proxy voting is an important and time-consuming operation used by a listed exchange. The application of blockchain technology can allow shareholders to vote without having to attend the company's annual meeting. People can vote using their mobile phones, and Always keep voting records. Blockchain technology is regarded as an advanced technology in the field of equity trading that can ensure transparent transactions in a shorter time.
5. Bank Credit Reference
At present, when developing commercial bank credit business, whether it is for enterprises or individuals, the most basic consideration is the financial credit of the borrower itself. Each bank uploads the repayment status of each borrower to the central bank's credit reference center. When inquiries are needed, the bank will download the reference from the central bank's credit reference center with the customer's authorization. There are problems such as incomplete information, inaccurate data, low usage efficiency, and high usage costs. In this area, the advantage of blockchain is that it relies onRelying on program algorithms to automatically record massive amounts of information and store it on every computer in the blockchain network, the information is transparent, highly difficult to tamper with, and low in cost of use. Commercial banks store and share customers' credit status in their own institutions in an encrypted form. When applying for a loan, customers do not have to go to the central bank to apply for a credit check, that is, decentralization. The lending institution can retrieve the corresponding information data from the blockchain. Complete all credit reporting work.
In short, blockchain has become one of the hot spots of innovation in the financial industry. However, as a new technology, blockchain also has considerable risks. The current settlement system based on blockchain technology is very sensitive to regulatory risks. If participants are worried about the uncertainty of regulatory policies, it may cause the payment system to collapse due to instability. In addition, since its operating rights are controlled by developers, the obvious technical disadvantage is that if the operator itself controls more than 51% of the computing power of the entire network, it can achieve double payment, leading to a breakdown of trust. This is also an important issue that needs to be solved during the application of blockchain technology.

『四』 What is blockchain anti-counterfeiting technology

Blockchain anti-counterfeiting technology is a way to convert goods into products through blockchain technology. The circulation records of raw materials are written into the blockchain, marking the source and historical geographical information of the commodity, and achieving authoritative proof across time, place and space through digitization. Blockchain technology is used to store historical circulation information, simplifying complex information systems, so that second-hand goods can also be managed in a unified manner, thereby achieving convenient, credible, and authoritative anti-counterfeiting monitoring. In terms of expansion, the application of blockchain anti-counterfeiting technology can not only be used to monitor the quality of goods, but can also be used to prevent products from being counterfeited and ensure the authenticity of high-end products, such as watches, diamonds, jewelry, etc., to maximize the publicity. Zheng Jiao improves the trust of business people and protects the rights and interests of consumers.

『五』Bitcoin doubled in February, “blockchain + finance” is hot, what should you do to have a chance

Undoubtedly, Bitcoin If the currency is a gold mine, the blockchain is the cart that transports the gold mine. A few years ago, people only paid attention to the gold mine itself, but later it was discovered that the more valuable thing was this small cart, which in addition to being able to load gold ore, it can also hold more other things, such as equity, debt, accounts... This is the future, and the future is already here, but it is not popular yet.

So, Xiao Haozi wants to say that young people who are interested in blockchain + finance should live in the future and make what is missing. Don’t create concepts and make quick money, and play with technology. The new heights of finance, your future, is truly a sea of ​​stars.

『Lu』 How to make money with blockchain

Blockchain technology will eventually move towards a "decentralized" "demand docking chain network" that can be connected with demand If you have something, you will definitely make money.

Not to mention the participation of some e-commerce giants, even small and medium-sized enterprises, individual investors, and entrepreneurs are deeply involved in blockchain technology, because everyone knows that in In such an undivided field, everyone can use blockchain technology companies to realize the development potential of entering the road to wealth! Those who hesitate are giving others the opportunity to "get there first".

『撒』Will the competition for blockchain patents become an important competitive area in the future?

The "Bluestone Blockchain Technology White Paper" released yesterday shows that the current blockchain Chain technology has gradually extended from the field of financial technology to include supply chain finance, credit reporting, traceability and other fields. However, at the technical level, it still faces pain points such as scalability, consensus mechanism, and data storage. Regarding the future development trend of the blockchain industry, the "White Paper" believes that the industry will accelerate the application of blockchain technology, present diversified optimization solutions to solve performance problems, consider security issues from an overall perspective, and fight for blockchain patents will become an important issue. In the field of competition, it has become a consensus to accelerate the improvement of supervision and standard systems and build a trustworthy blockchain ecosystem. Therefore Vocean can seize the opportunity

『8』 What earth-shaking changes will blockchain bring and how will it change life

In addition to being used in the financial industry, blockchain is also Application in other fields. In fields such as law, retail, Internet of Things, and medical care, blockchain can solve trust problems, no longer rely on third parties to establish credit information sharing, and improve the operating efficiency and overall level of the entire industry. Extremely high productivity will connect all people and machines in this society into a global network, and mankind will accelerate towards an era where goods and services are almost free. Perhaps by the second half of the 21st century, capitalism will decline and areas The decentralized collaborative sharing model of the blockchain will replace it and become the new model that dominates economic life.

Blockchain is the best technical means for this new collaborative sharing model. The infrastructure of blockchain allocates global resources in a decentralized manner, making blockchain an ideal technical framework for promoting social and economic development. The operational logic of blockchain is to optimize peer-to-peer resources and global coordination.work and foster and encourage the creation of social capital in society. Establishing various platforms for blockchain can encourage a collaborative culture to the greatest extent, which complements the original shared model and will make it the decisive economic model of the 21st century.

『玖』 What are the application prospects of blockchain technology?

Blockchain classification:

1 Private chain

refers to There is a certain degree of centralized control of the blockchain. Just using the general ledger technology of the blockchain for accounting, it can be a company or an individual, with exclusive write permission to the blockchain. This chain is not much different from other distributed storage solutions. The only participating nodes are the users themselves, and data access and use are subject to strict permission management. Since the alliance chain has certain centralized control, it can also be considered to belong to the category of private chain.

Features: Since the user has the final say, the data inside has no characteristics that cannot be changed, and there is not much protection for third parties. Generally used for internal audit. The vice president of technology at Huobi Network believes that private chains do have a large number of scenarios that can meet the needs of the real world. Limited decentralization makes it easier to reach consensus, can make transactions faster and more efficient, and can provide more controlled function. Decentralization is the core value of blockchain technology. If the private chain cannot fully utilize the decentralized trust foundation constructed by the public chain in practice, its development space will be limited.

2 Public Chain

Public blockchain is the earliest blockchain and the most widely used blockchain at present. It refers to a blockchain like the Bitcoin blockchain that is completely decentralized and not controlled by any institution. Any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Participants in the consensus process maintain the security of the database through cryptography and built-in economic incentives.

Features: Completely open, uncontrolled, relying on encryption technology to ensure security.

3 Alliance Chain

A certain group designates multiple pre-selected nodes as bookkeepers. The generation of each block is jointly decided by all pre-selected nodes. Other access nodes You can participate in transactions, but you are not involved in the accounting process (it is essentially still managed accounting, but it becomes distributed accounting. How many pre-selected nodes and how to decide the accountant of each block becomes the main risk point of the blockchain) , anyone else can make limited queries through the blockchain’s open API.

The nodes participating in the blockchain are selected in advance, and there are likely to be good network connections between the nodes. Other consensus algorithms other than proof of work can be used on such a blockchain. For example, a certain blockchain has been established among 100 financial institutions, and it is stipulated that more than 67 institutions must agree to reach a consensus.

Prospects:

The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted new developments in various industries.The impact of this driving force on society and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting and watching, expecting this brand-new technology to be used by various industries and better benefit all industries.
