A. How to define blockchain and what are its application scenarios
Many people now think that blockchain is a universal technology that can do anything. It’s a bit of a myth about blockchain technology!
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 be operated collaboratively in various places is different from traditional database operations where read and write permissions are in the hands of a company or a centralized authority (a characteristic of centralization). 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 system that connects data blocks in an orderly manner and cryptographically ensures that they cannot be tampered with.Distributed ledger (database) technology that cannot be changed or forged. 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 released 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., core enterprises issue accounts receivable vouchers to their suppliers. The bills can be transferred between suppliers after being digitized on the chain. Each level of supplier can use the digital bill certificate to realize the corresponding amount. Financing.
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 greatly reduce tax collection and management costs, and effectively solve problems such as data tampering, over-reporting of one ticket, and tax evasion. 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 haveEffectively 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-signing products for certificate deposit and certificate issuance. The application scenarios include copyright protection and online signing. , web page forensics, phone recording, email storage of evidence, 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 electricitySub-contract refers 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 an integration of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, smart contract and other computer technologies. New application model. Specifically, blockchain technology is a technical solution that collectively maintains a reliable database in a decentralized, high-trust manner.
Due to the characteristics of "decentralization" and "distribution" With advantages such as "automatic data storage", "traceability", "tamper resistance", and "openness and transparency", blockchain technology can effectively solve the problems of data authenticity, security and openness in the data field. A data management environment to prevent and avoid various data management problems such as data fraud, tampering, and loss, and promote efficient sharing and application of data. In the process of practical exploration, the application scope of blockchain technology continues to expand, especially in the field of public resource transactions. Empower public resource transaction management services.
Promote transaction data sharing and transaction witness
Promote transaction data sharing
Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be entered repeatedly. During the bid evaluation process, it is difficult to verify the off-site performance provided by the bidders, and the same personnel are duplicated. Problems such as difficulty in troubleshooting as a project manager and low cost of breach of trust by transaction entities. Establishing a cross-regional entity database based on blockchain can well alleviate the above problems.
The distributed ledger features based on blockchain can Effectively guaranteeing the real-time or quasi-real-time sharing of data, it can reduce repeated entry operations of subject information; the use of blockchain information that cannot be tampered with can ensure the authenticity of the data flow process on the chain. The performance of bidders in the regional alliance is directly taken from the data on the chain. This makes it impossible to hide false 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".
p>
Blockchain-based transaction witness
The document "Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" (State Office Letter [2019] No. 41) points out the need to optimize witness, venue, Information, archives, expert extraction and other services. However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing strength, high occupation of human resources, and limited witnessing effect. Due to its centralized characteristics, the traditional digital witnessing system is easy to collect data afterwards Be tampered with, 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 verify each transaction The data generated in the link are solidified and stored as evidence, and are processed through timestamp technology and summary calculation.Law, electronic signature technology accurately records the time, content and data source of data generation. 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 letters have certain applications in the field of bidding, solving the problem of bidding deposit funds for bidding companies. Occupancy issues. 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 sustainable profitability, but most small and medium-sized enterprises cannot produce these "proofs" at all. Difficulty and expensive financing have become a problem for many small and medium-sized enterprises in bidding activities.facing problems. 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. The 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.
Blockchain can have economic benefitsWhat applications?
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. So in the Internet, a place where data and information explode, how can there be such a thing?This place will be like a magical treasure land.
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.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They 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.
B. What is blockchain and what is its use? Will it become a new trend?
Three questions about blockchain (economic hot spots)
p>In recent times, news about Bitcoin has been very eye-catching, and blockchain has also become popular. In the capital market, the stock prices of various blockchain concept stocks rise and fall like a thrilling roller coaster. It can be seen from the responsive capital market that blockchain is on the forefront and has received great attention from all parties.
"Blockchain technology is essentially a database technology, specifically a ledger technology. The ledger records the asset changes and transactions of one or more accounts. In fact, it is A database with the simplest structure. The running accounts we usually write down in small notebooks and the statements sent by the bank are all typical account books." Wang Jun, chief researcher of Tencent Financial Technology Think Tank, said that security is an aspect of blockchain technology. Its major features are mainly reflected in two aspects: first, the distributed storage architecture, the more nodes, the higher the security of data storage; second, its tamper-proof and decentralized ingenious design, it is difficult for anyone to not follow the rules change the data.
Take online shopping transactions as an example. The traditional model is that the buyer purchases the goods and then transfers the money to the intermediary platform of a third-party payment institution. After the seller ships the goods and the buyer confirms receipt, the buyer will then notify the payment The institution transfers the money to the seller's account. The transaction model supported by blockchain technology is different. Buyers and sellers can trade directly without going through any intermediary platform. After the buyer and seller trade, the system releases the transaction information through broadcast. All hosts that receive the information record the transaction after confirming that the information is correct, which is equivalent to all hosts making data backups for this transaction. Even if there is a problem with a certain machine in the future, it will not affect the data recording, because there are countless machines as backup.
When it comes to blockchain, many people associate it with Bitcoin, and many people even equate blockchain with Bitcoin. He Fei said that Bitcoin is a presentation method of blockchain, but blockchain is not the same as Bitcoin. Blockchain is the underlying technology and infrastructure of Bitcoin, and Bitcoin is a successful application of blockchain, but it does not mean that blockchain can only be applied to Bitcoin.
What is the use of blockchain?
It can solve the pain points and difficulties in many fields such as finance, public welfare, supervision, and anti-counterfeiting, but there are many applicable conditions
Financial services are the first application field of blockchain technology. The use of blockchain technology can solve pain points in many fields such as payment, asset management, and securities.
Take the payment field as an example. The cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, is high and involves many manual processes. The high fees also make it difficult to carry out micropayment business. The application of blockchain technology can help reduce the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing efficiency of payment services. In addition, the cost and efficiency advantages that blockchain technology brings to the payment field enable financial institutions to better handle small-amount cross-border payments that were previously considered unrealistic due to high costs, helping to achieve inclusive finance.
For example, to solve the problem of financial institutionsIn order to solve the problem of high inter-institution reconciliation costs, in August 2016, WeBank and Shanghai Huarui Bank launched the Weilidai inter-institution reconciliation platform. This is also the first domestic banking alliance chain application scenario that runs in a production environment. Zhang Kaixiang, chief architect of WeBank’s blockchain, believes that the high cost problem that the traditional “batch file reconciliation” model has not been able to solve for a long time is where blockchain technology comes in. Subsequently, Luoyang Bank and Changsha Bank also successively connected to the inter-institution reconciliation platform. Through blockchain technology, they optimized the inter-institution reconciliation process in the micro-loan business, achieving quasi-real-time reconciliation, improving operational efficiency, and reducing operating costs. Target. Up to now, the platform has been running stably for more than a year, maintaining zero failures, and the number of real transactions recorded has reached tens of millions.
In the field of public welfare, blockchain technology also has great potential. Ant Financial's first application scenario involving blockchain was public welfare, helping a group of hearing-impaired children obtain a donation, and then using blockchain technology to promote public welfare to be more open and transparent. Hu Danqing, senior product expert at Ant Financial Technology Lab, said: "The blockchain charity platform is like us building a post office on the Internet specifically for mailing funds. Every money donated by users, we will package it into a The package is delivered through the blockchain platform. Every time it passes through a node, we will stamp a postmark and finally deliver it to the recipient. This ensures that every money donated by users is transparent, traceable, and difficult to tamper with. ”
Blockchain technology can play a big role in combating counterfeit goods. Hu Danqing introduced that Ant Financial uses blockchain technology to trace the origin of authentic products. At present, there are some overseas shopping products from Australia and New Zealand, such as milk powder. You can use Alipay to scan the products to know whether they are genuine. "Unlike the previous self-entered product information by merchants, blockchain allows multiple 'bookkeepers' to complete accounting fairly, independently, and non-repudiation."
For financial supervision, blockchain Technology can also play a role. The "Financial Blockchain Underlying Platform FISCO BCOS White Paper" released by the Financial Blockchain Cooperation Alliance (Shenzhen) in 2017 believes that blockchain provides financial regulatory agencies with consistent and easy-to-audit data. Data analysis can supervise financial businesses faster and more accurately than traditional audit processes. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly enhance anti-money laundering efforts.
Some people in the industry believe that blockchain 1.0 is mainly aimed at digital currency; blockchain 2.0 is aimed at smart contracts and can be applied in the financial market; blockchain 3.0 will be applicable to more scenarios, and even Create a "blockchain era".
He Fei believes that blockchain can indeed solve the pain points and difficulties in many fields, but blockchain is not a panacea and has many applicable conditions.
For example, the decentralized nature of blockchain technology is suitable for scenarios involving multi-party participation. If it is only unilateral or bilateral participation, it will be of little value.Since each node needs to be checked, blockchain technology is not suitable for high-frequency trading activities.
For another example, blockchain emphasizes openness and transparency and is not suitable for scenarios with particularly high data privacy requirements.
Will blockchain become a new trend?
The technology is not yet mature, so we must be wary of concept hype, and we must distinguish between technological innovation and fund-raising innovation. We cannot use blockchain for the sake of blockchain
The concept of blockchain is so Will Fire become another “Internet+” in the future?
In recent years, the development ecosystem of blockchain has gradually been improved and enriched. Industry insiders believe that with national policy support, widespread attention and financial support, blockchain technology can achieve gradual and stable progress. Although the upside prospects of blockchain technology are broad, we must remain calm about this.
“Although blockchain is very popular right now, we still believe that it is still in a very early stage.” Hu Danqing said that there is currently false enthusiasm in the blockchain concept, and it is not that the technology is used to solve the problem. The real problem is that the focus is on raising funds to make money and hyping valuations. In particular, most of the so-called ICOs (Initial Coin Offerings) that are so popular are innovations in fundraising tools and have nothing to do with technological innovation.
Blockchain technology can indeed create great value, but some risks cannot be ignored.
“Blockchain technology is not yet mature, and its application scenarios are relatively limited. We should be more wary of the concept of capital market speculation.” He Fei said that behind the blockchain boom, there will inevitably be some gimmicks and speculation. Companies that do not really carry out business, but just try to make a profit in the capital market and leave. We must be careful to prevent the occurrence of "bad money driving out good money", causing institutions that really want to do business to withdraw from the market, affecting the development of blockchain technology. application.
Hu Danqing suggested that for the current blockchain craze, regulatory authorities should intervene more proactively, distinguish between technological innovation and fund-raising innovation, and encourage government organizations, credible experts, and industry participants to jointly help the public Identify and comprehensively curb fund-raising innovation in the name of blockchain, so that the actual controller of ICO must bear responsibility for the fund-raising behavior. "The basis for judging whether it is technological innovation or fund-raising innovation is actually very clear, that is, whether it starts with trust and whether it creates actual value by solving the trust problem."
Better promotion and use of blockchain technology in the future , it is necessary to continue to improve infrastructure and strengthen the formulation of relevant laws and policies.
Wang Jun believes that there is still room for optimization and improvement in core blockchain technologies such as consensus algorithms; on the other hand, the processing efficiency of blockchain is still difficult to reach that of some high-frequency application environments in reality. Require. At present, the mainstream blockchain technology platforms all originated from abroad. Domestic blockchain technology service providers must patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. Enterprises with blockchain application scenarios must actively embrace new things and scientifically evaluate their on-chain needs. They cannot use blockchain for the sake of blockchain.
He Fei believes that the government can introduce relevant policies to guide those who are interested in joining the blockchain industry.Enterprises that develop and apply blockchain technology, while clarifying some suitable application scenarios for blockchain and areas encouraged by the state.
The "China Blockchain Technology and Application Development White Paper 2016" recommends that government departments at all levels learn from the advanced practices of developed countries and regions, combine the development of my country's blockchain technology and applications, and promptly introduce blockchain Technology and industrial development support policies focus on supporting key technology research, major demonstration projects, "mass entrepreneurship and innovation" platform construction, system solution research and development, and public service platform construction. At the same time, it is recommended that key domestic enterprises, scientific research, universities and user units strengthen cooperation to speed up research on core key technologies such as consensus mechanisms, programmable contracts, distributed storage, and digital signatures.
If it can bring money to the enterprise, it will become a hot topic.
C. What are the current applications of blockchain?
What is blockchain technology? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
my country's current economic and social credit environment is still relatively weak and credit costs are high. Blockchain technology proposes a set of lower-cost "trust" solutions to reduce the credit costs of the whole society, which is very important for promoting our country. The development of credit economy is of great significance. Although this technological innovation in the field of Internet finance is not yet mature, many large banks in the world have rushed to invest resources in research and development, which should attract the attention of my country's banking industry and regulatory authorities.
(1) As for commercial banks, they should prepare technology and talent reserves and actively participate in the formulation of international standards.
In order to prevent digital currency risks, my country’s commercial banks are currently unable to conduct digital currency transactions, and the research on technological innovation behind digital currencies is also lagging behind. This is slightly asymmetrical with my country’s private enthusiasm for blockchain research and development. . Nowadays, the development of emerging models of disintermediation such as blockchain technology and P2P is gradually moving from concept to application, driven by the joint innovation of large global financial institutions. my country's major banks should also pay close attention to the latest innovation trends of international peers and join the research as soon as possible. , develop the ranks of blockchain products and promptly adjust development strategies to adapt to the business operation model of Internet finance under the new situation. First, it can establish a research and development laboratory or cooperate with financial technology companies. In addition to developing different blockchain application scenarios, it can also be combined with national conditions and inclusive finance, such as studying how to use blockchain technology to achieve low-cost fund transfer payments in economically underdeveloped areas and improve financial services in these areas. The second is to actively participate in the formulation of international standards and agreements, strive for the right to speak, and avoid being a passive follower.
(2) Regulatory agencies also need to continue to pay attention to the development of the latest Internet technology and be prepared to respond.
First, the "decentralization" brought by blockchain technology does not mean that centralized organizations are not needed in economic operations. Blockchain technology hopes to break privileges and human manipulation,Let computer algorithms realize "free credit notarization". But from a practical point of view, theoretical deductions cannot be completely mapped to real life. For example, due to the lack of supervision, digital currency transactions such as Bitcoin face high risks of speculation and money laundering. Therefore, if blockchain technology wants to become a new channel for capital circulation, it needs supervision and implementation standards to protect the interests of all parties in the market. In this regard, regulatory authorities should formulate relevant standards and specifications, especially operating specifications, and use their power to ensure that financial innovative products are used rationally; at the same time, they should also improve the protection of consumer rights and interests, strengthen education on the protection of financial consumer rights and interests, and improve consumer awareness. Risk prevention awareness. In short, even in a "decentralized" business system, centralized departments are needed to provide normative and guarantee support.
Second, regulatory authorities must be prepared to respond to possible changes in regulatory methods. At present, new technologies have a profound impact on the monetary systems of various countries, and the traditional policy framework and means of regulating economic and financial affairs are increasingly unable to keep up with the changes in the situation. Regulatory authorities should keep pace with the times and make full use of the convenience of financial technology to improve supervision methods and improve supervisory means. For example, if securities lending, repurchases, and margin trading can all be traded through a transparent and open blockchain in the future, then regulatory authorities can consider using this public ledger information to monitor systemic risks in the market, which is not only efficient but also reliable.
Third, regulatory agencies can proactively embrace new technologies in Internet finance. Central banks can respond in two ways to a financial landscape transformed by technology: monitor and respond to developments or take a proactive approach. U.S. Securities and Exchange Commission Commissioner Kara Stein believes that regulatory agencies need to be in a leading position to take advantage of the advantages of blockchain technology and respond quickly to its potential weaknesses. The Bank of England's research further stated that the central bank may consider issuing blockchain-based digital currencies in the future, which if done properly can increase financial stability.
Blockchain was first launched and recognized by people to support the formation and circulation of Bitcoin. However, unlike the controversial Bitcoin, the introduction of blockchain technology has adapted to the development of the Internet. After entering a new era of mobile Internet, Internet of Everything, and anytime Internet, a large number of online transactions are in urgent need of party identity verification and transaction confirmation. , greatly improve the efficiency of transaction settlement and clearing, and ensure the urgent needs of funds and information security. Therefore, blockchain technology has received increasing attention and attention, and attracted more and more people to explore, innovate and apply. .
By the end of 2015, more than 20 of the world's top financial institutions have begun to explore the application of blockchain technology at the financial level. More and more people believe that blockchain technology uses new encryption authentication technology and decentralized mechanisms to maintain a complete distributed, non-tamperable, continuous ledger database, which allows participants in the blockchain to The security of funds and information is ensured through a unified ledger system without the need for mutual recognition and trust. This is of extremely great significance to financial institutions and financial innovation.
First, blockchain technology can reduce trust risks.
Blockchain technology is open source and transparent, and system participants can know the operating rules of the system. Under blockchain technology, since each data node can verify the authenticity and integrity of the ledger content and ledger construction history, it ensures that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system. , reducing the trust risk of the system.
Second, from an enterprise perspective, Bubi blockchain has been used in equity, supply chain, points and other fields, and is conducting trials and application tests with exchanges and banks. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. And many blockchain innovative and entrepreneurial companies are constantly emerging.
Third, blockchain can drive the birth of new business models.
The characteristics of blockchain technology enable it to realize some business models that are difficult to achieve in a centralized model. For example, in the Internet of Things industry, some organizations have proposed using blockchain technology to manage the identity, payment and maintenance tasks of tens of billions of Internet of Things devices. Using blockchain technology, IoT device manufacturers can greatly extend the life cycle of products and reduce the cost of IoT maintenance.
Fourth, blockchain technology has a flexible architecture.
Based on different application scenarios and user needs, blockchain technology can be divided into several types: public chain, private chain and alliance chain, which can be selected according to the actual use of the organization.
Fifth, blockchain technology is a beneficial tool for realizing shared finance.
The essence of shared finance is to achieve the purpose of optimizing the allocation of financial resources by reducing the asymmetry of financial information, and through strict third-party certification and supervision mechanisms to ensure the implementation of the rights and interests of both parties to the transaction and facilitate the completion of the transaction. By using blockchain technology, financial information and financial value can be more strictly protected, enabling more efficient and lower-cost flows, thereby realizing the sharing of value and information.
Sixth, the openness of blockchain technology encourages innovation and collaboration.
Through the openness and collaboration of source code, blockchain technology can promote collaboration among different developers, researchers, and institutions and learn from each other's strengths to achieve more efficient and safer solutions. In recent years, many overseas financial institutions and commercial institutions have tried to use blockchain technology to improve business models. In China, although this technology has not yet been widely recognized and applied, it has begun to attract more and more widespread attention. Attention, its influence is rapidly increasing. Now blockchain technology has been regarded as one of the basic protocols for the next generation of global credit certification and value Internet. The importance of blockchain technology to my country's financial industry and financial system cannot be ignored.
Of course, we must know that the development of blockchain technology is still in its early stages globally, and various technical solutions, application scenarios and business models need further exploration.Search and perfect. Especially in our country, blockchain is a brand-new concept and theory, and people's cognition, research and practice have just begun. If we want to overtake in this field, catch up with the advanced, and lead the world, we still need enough attention. More investment requires the active investment and positive interaction of theoretical researchers, network technicians, financial practitioners, and regulatory authorities, and the courage to explore and innovate.
What is blockchain technology? People will definitely understand more and more about such technology, and it will play an increasingly important role in reality, and will be supported by many institutions, thus bringing the popularization of blockchain into a new application stage in reality.

E. Blockchain Encyclopedia: The Past and Present of Blockchain - 3.0 Era
The representative of the blockchain 1.0 era is Bitcoin, and the representative of the 2.0 era is Ethereum. And the troubled times of various copycats and air coins. Blockchain 3.0 is the era of consumer-level blockchain that has truly entered commercial and physical applications after the troubled times. The typical symbol is the emergence of tokens. The pass has brought about changes in traditional business models and production relations. The pass has moved from the digital world to the real economy and has begun to seek practical applications in various industries.
The pass has three elements, one of which is indispensable.
Pass: The pass can be circulated on a large scale in a network and can be verified anytime and anywhere; Certificate: As a proof of digital rights and interests, the pass must be a certificate of rights and interests that exists in digital form, and it must represent It is a right, an inherent and intrinsic value; value: the token must have economic value.
In this way, the meaning of "token economy" is not difficult to understand. The token economy is a large-scale group collaboration based on tokens. It maximizes the role of tokens, allows every role that creates value to share value fairly, fully mobilizes participation motivation, and forms a self-organizing form.
Major changes in the blockchain 3.0 era
The token economy has laid the theoretical basis and technical support for the large-scale application of blockchain, and the future world will also be transformed by it. Large-scale changes include:
1. Fragmented investment, fragmented income, subverting the traditional way of doing business on the Internet. In the traditional Internet era, it was impossible for ordinary people to participate in the investment of a company, but the emergence of blockchain allows ordinary people to make fragmented investments in a large asset. Assuming that Alibaba originally adopted blockchain for fragmented investment, then all fragmented shareholders who invested in Alibaba would be able to reap a return on investment that has increased thousands of times today!
2. Break the money-burning model of the Internet and make everyone a winner. The free model of the traditional Internet is essentially to obtain a large number of users through free products to form monopolies and barriers, and then make profits through advertising and value-added services on this basis. In the blockchain 3.0 era, project income is redistributed by issuing tokens to attract more early investors and community users. As the number of users holding tokens increases, the value of the tokens will become higher and higher, and community users, investors, and projects can all benefit from it. In this way, the money-burning model of providing free services in the early days of the traditional Internet can also be improved, and everyone will become a winner.
3. Breaking down the traditional corporate organizational hierarchy, self-organization may become a future trend. In the blockchain 3.0 era, through the establishment of distribution and collaboration mechanisms through smart contracts, it can be more efficient and accurate than enterprises. All token owners will naturally form a community. Everyone has the same goal - "to promote the development of the project and make it a success". They are all members of the community, contribute to the community, promote the value-added of the token, and thus gain benefits together. profit. From a philosophical perspective, this new self-organizing community of freedom, independence, and equality must be the future trend. Gojoy blockchain e-commerce is a blockchain self-organized community. Every consumer is a token owner and a fragmented investor, so he is very happy to co-create and build Gojoy value.
Therefore, we can look forward to the era of great development of the blockchain 3.0 token economy, and the existing ones may be subverted. What we need to be prepared for is to work hard to embrace the blockchain. If you want to seize the trend of blockchain and understand how to transform into blockchain, please leave a message to communicate and we will take you to learn the blockchain professional certification course.
F. WNN global wine industry traceability blockchain laboratory landed in Zhengzhou
August 10On the afternoon of the same day, the WNN Global Wine Traceability Blockchain Laboratory signed a contract with a well-known wine company and the mall launch ceremony was held in Zhengzhou. Cai Kaisheng, President of North China Region, delivered a speech. Assistant to the President of the China Liquor Circulation Association and Vice President of the Henan Liquor Association Wu Yong explained the application of wine chain in the wine industry. Wuliangye Group, Grande Imported Red Wine Franchise, Henan Shuntianzhai Rice Wine and Renyi Online Mall signed long-term cooperation agreements with wine chain WNN. It was announced at the meeting that the WNN Global Wine Industry Traceability Blockchain Laboratory has landed in Zhengzhou. The technical staff also demonstrated the entire process of the mall transaction operation at the conference site. WNN wine chain investment enthusiasts from all over the world witnessed this wonderful moment. Everyone believes that the application scenarios of the wine chain WNN have been implemented, and the wine chain WNN is more valuable.
According to reports, WNN wine chain was launched on June 27, successfully logged into the International Trading Market Gold Coin Network on July 27, and the online mall was launched on August 10. It is expected to take 4 to 6 months before landing. The top 5 digital asset exchanges are ZB.com and ok.com.
The industry generally believes that counterfeit wine is a pain point in the wine industry. Counterfeiting and shoddy products may occur in raw materials, production, testing, logistics, distribution, terminals and other links: fake raw materials, fake wine, expired, package swap, etc. Cross-border goods, etc., and the source cannot be traced. The wine industry chain utilizes the traceability, non-tampering, decentralization, openness, anonymity, timestamp and other characteristics of blockchain technology and applies them, so that the wine industry supply chain system can obtain a transparent and reliable unified information platform, which can realize real-time Check the status, reduce logistics costs, trace the entire production and delivery process of items, thereby improving the efficiency of supply chain management. When disputes arise, proof and tracing have become clearer and easier. Put an end to all counterfeiting, authoritatively trace the source of all violations, and use blockchain technology to prevent consumers from buying fake wine. Production companies can solve the problem of fake wine at the lowest cost. The combination of blockchain technology and the real economy has opened up a new era. Blockchain has huge commercial value, thereby achieving win-win for all.
The first domestic blockchain industry white paper "2018 China Blockchain Industry Development White Paper" officially released by the Information Center of the Ministry of Industry and Information Technology this year shows that from the current trend, due to the implementation of blockchain technology The pace is accelerating, the market is becoming more rational, and equity investors are more willing to invest in projects where they can see specific implementation scenarios. In terms of the industrial chain structure, my country's blockchain industry chain has now been formed, from upstream hardware manufacturing, platform services, and security services, to downstream industrial technology application services, to industry investment and financing, talent services, etc. to ensure industrial development. The fields are basically complete and the collaboration is orderly, which will jointly promote the continuous advancement of the industry.
At the meeting, experts also explained the six major development trends of the blockchain industry, namely: blockchain has become the forefront of global technological development and opened up a new track for international competition; the blockchain field has become createA new hot spot for new entrepreneurship, technological integration will expand new application space; blockchain will be widely implemented in the real economy in the next three years, becoming an important support for the construction of digital China; blockchain will create a new platform economy and open up a new era of sharing economy Times; blockchain accelerates the process of "trusted digitization" and drives finance to "shift from reality to reality" to serve the real economy; blockchain supervision and Congyinjiao standard systems will be further improved, and the foundation for industrial development will continue to be consolidated.
G. Blockchain has officially entered the 3.0 era, and real estate, supply chain, etc. will become key areas of application
With the continuous development of blockchain, the scope of blockchain application coverage More and more widely, with the improvement of scalability and efficiency, the application scope of blockchain will go beyond finance and expand to fields such as logistics, real estate and the Internet of Things, becoming a bottom-level protocol in the future society, which means As the blockchain will enter the 3.0 era.
The blockchain 1.0 era is represented by BTC (decentralized concept), which plays more of a distributed accounting role, such as BTC, Ripple, BCH, Litecoin, Dogecoin, etc. It is more used for digital currency accounting. Of course, the development in the first stage is not perfect. Bitcoin still has many problems that need to be solved, such as expansion, lightning payments, hard forks, etc.
With further completion, the blockchain has entered the 2.0 era, represented by ETH (smart contract), entering the contract stage.
Blockchain 2.0 represented by ETH is a great progress, but there are still many problems, such as channel congestion, slow transaction speed, and fork risk. High handling fees and so on. For example, after the popular CryptoKitties were launched on the Ethereum platform, they occupied about 25% of the Ethereum network at its peak, causing congestion on the entire Ethereum network and seriously affecting the experience of other Ethereum users. . The current development is a transition process from the first stage to the second stage.
After bidding farewell to the 1.0 and 2.0 eras, thanks to the continuous development of technology, blockchain has become more practical. This also means that the blockchain will completely break away from the financial attributes of the start-up period and enter practical application scenarios in all walks of life with its decentralization and other characteristics.
This also means that the blockchain has officially opened its 3.0 era - the era of comprehensive application. The blockchain industry structure in the 3.0 era is also more complex. Today I will give you a brief analysis.
The blockchain industry in the 3.0 era is divided into three levels: basic layer, service layer and application layer.
(1), base layer
The corresponding upper, middle and lower reaches of the industry chain include: upstream underlying technology and infrastructure (core technology, equipment, underlying platform deployment methods), the midstream service layer mainly provides developers with applications based on blockchain technology; the downstream application layer includes finance, Supply chain management, intelligent manufacturing, government enterprises, services, social applications, etc.
Hardware, technology and infrastructure manufacturers mainly provide chips, mining machines, mining pools, hard drives, routers and other infrastructure necessary for blockchain applications.
The underlying platform deployment methods can be divided into public chain, alliance chain, and private chain.
The underlying technology includes core basic components, protocols and algorithms. Based on the underlying core technology components, it provides different functions for different application scenarios, including smart contracts, programmable assets, incentive mechanisms, member management, etc.
The base layer provides the underlying blockchain or distributed ledger technology framework, mainly including Ethereum, Hyperledger Fabric, R3 Corda, FISCO BCOS, etc.
(2) Service layer
The service layer refers to the BaaS (Blockchain as a Service) platform. The main domestic BaaS platforms are Ant Blockchain BaaS platform, Tencent Cloud TBaaS, Ping An One Account BaaS platform, etc.
It mainly provides developers with applications based on blockchain technology, and provides smart contracts, information security, data services and other products based on the underlying technology. services to improve the convenience and scalability of developers developing applications at the platform layer.
Application and service vendors are responsible for the research and development of general blockchain technology and technology expansion platforms, digital currency education and storage platform construction, etc., and provide technology for the industry application layer. support.
(3) Application layer
The application layer is represented by core application components, including smart contracts, programmable assets, incentive mechanisms, member management, etc.
Refers to the end user or service provider of blockchain. The main application scenarios of blockchain now include cross-border payment, anti-counterfeiting traceability, and supply chain. Finance, trade finance, electronic bills, ABS, etc.
Service objects are divided into two categories: B-side (initial stage): blockchain + (finance, supply chain management, copyright protection, education); C-side (first to land): blockchain+ (sharing economy, pan-entertainment).
The downstream blockchain application field is the combination of blockchain technology and existing industries. Now, many industries have started the application of blockchain 3.0 era.
(1) Blockchain + supply chain
Blockchain + supply chain enables full-process traceability of product information. The traceability and anti-counterfeiting system of the traditional supply chain has shortcomings such as opaque information, easy data tampering, poor security and relative closure. However, using blockchain technology and Internet of Things technology, the information on the raw material purchasing process, production process and circulation process of goods can be processed. Integration and traceability can truly realize the full-process authentic traceability across brands, channels, retailers, and consumers, down to each item and code, significantly improving user trust experience.
(2), Blockchain + Internet of Things
Build an information exchange network in the era of Internet of Everything. As the number of devices in the Internet of Things grows, the distributed nature of the blockchain provides a way for self-governance of the Internet of Things, which can help devices in the Internet of Things understand each other and understand the correlation between different devices, thereby realizing the distribution of the Internet of Things. type control.
(3), Blockchain + Medical
Ensure the safe sharing of medical data. Using blockchain technology to mathematically encrypt medical data can effectively prevent risks such as malicious modification of medical data. The medical data sharing and exchange system developed using blockchain technology uploads encrypted medical data, allowing data to be shared and circulated quickly, efficiently and securely between patients and medical institutions, effectively simplifying the management of medical data. Call process to provide data guarantee for accurate diagnosis of illness.
(4) Blockchain + Real Estate
There are many potential application scenarios of blockchain in the real estate industry. Common ones include: Real estate transactions. Pain points in the process of buying and selling property include: lack of transparency during and after the transaction, reams of paperwork, potential for fraud, errors in public records, and that’s just to name a few. Blockchain provides a way to achieve the need for paperless and fast transactions. In addition, real estate blockchain applications can help record, trace and transfer title deeds, deeds, liens, etc., and also provide a platform for financial companies, title companies and mortgage companies. Blockchain technology strives to securely preserve files while enhancing transparency and reducing costs. In addition, blockchain is also applied in the field of construction engineering, and many companies are applying this technology in the current urban renewal boom. For example, Shenzhen's Lanfang Chain has proposed a package of solutions such as blockchain + urban renewal/construction engineering/real estate development based on blockchain, which comprehensively serves many fields in the real estate industry. Currently, its official website, mobileThe applications are all online.
In addition, blockchain has already had many applications in supply chain finance, stock trading, banking, etc., so I won’t go into details here.
As one of the important contents of my country’s 14th Five-Year Plan, officials have already proposed to accelerate the promotion of blockchain Technological and industrial innovation and development, and actively promote the integrated development of blockchain and economy and society.
The key to achieving the above two developments lies in the following two points:
1. Breakthrough in the core technology of blockchain technology.
Blockchain technology is currently the technology with the smallest gap between my country and Europe and the United States. Officials particularly emphasize that in this emerging field, my country must be at the forefront of theory, occupy the commanding heights of innovation, and gain new industrial advantages. It is necessary to promote collaborative research, accelerate breakthroughs in core technologies, and provide safe and controllable technical support for the development of blockchain applications.
At present, most of the blockchain technology is still in the conceptual hype stage, and many business scenarios use blockchain purely for the sake of blockchain. So far, no one in our country has been able to solve core technical dilemmas such as the ternary paradox on a global scale. Therefore, we must return to basic theories and core technologies and achieve major breakthroughs through long-term and concentrated research.
In fact, the official has put forward very high requirements for the theoretical technology and subsequent application development of blockchain technology. Do a good job in basic theoretical research on blockchain, Focusing on conquering a number of key core technologies and truly shouldering the burden of technology research and development is the key to the current development of blockchain.
2. Enhance international voice and rule-making power.
Different from previous information technologies, blockchain technology is highly scalable, or aggressive. Its rules or right to speak determine its scope of influence, because every business on the chain is Individuals or institutions must obey the rules set by the blockchain, whether at home or abroad. For example, everyone must obey the rules of Windows when using the Windows system, but Windows only stipulates the rules for information interaction for users, which is acceptable to us, while the blockchain stipulates industry governance rules. With its distributed characteristics, the governance rules of the blockchain can quickly transcend national borders and geographical restrictions.
In order to achieve the above two points, we must strengthen the construction of the talent team, establish and improve the talent training system, create various forms of high-level talent training platforms, and cultivate a Group of leading figures and high levelInnovation team.
Blockchain, as an architectural innovation technology, has a huge demand for comprehensive talents, requiring practitioners to master a variety of professional and technical knowledge involving cryptography, information science, basic mathematics, etc. To develop blockchain, we must strengthen the construction of a talent team with deep cross-integration of disciplines, and establish a talent cultivation system in a forward-looking and systematic manner from the aspects of basic research, applied research and development, and industrial integration.
Blockchain technology is an important part of the future digital economy and has rich advantages for all walks of life. Although we have entered the 3.0 era, the vertical application of blockchain in various industries has just begun.
What do you think of the future of blockchain?
