OK, if necessary, your inquiries are always welcome.

⑶ How to define blockchain and what are the application scenarios of blockchain?

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

Definition of Blockchain: Narrow VS Broad

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

Blockchain technology features include:

Blockchain is a global A database storage system that can 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. People often hear people say that if you buy the right coin a hundred times, a bicycle will become a sports car, and a young model can be transformed into a new model with one coin.You can imagine how attractive it is.

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

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

Digital currency

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

Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also 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 on-chain transactions and quickly locate high-risk capital flows. In terms of securities issuance transactions, the traditional stock issuance process is long, costly and complex, and blockchain technologyThis technology can weaken the role of underwriting institutions and help all parties establish a fast and accurate information exchange and sharing channel. Issuers can handle issuance on their own through smart contracts, and regulatory authorities can conduct unified review and verification. Investors can also bypass intermediaries for direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we can establish a consortium chain network covering core enterprises, upstream and downstream suppliers, financial institutions, etc. The core enterprises issue accounts receivable vouchers to their suppliers. After the bills are digitized and uploaded to the chain, they can be uploaded to the supplier Transfer between them, each level of supplier can realize the corresponding amount of financing with the digital bill certificate.

Digital Government Affairs

Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to be centralized on one chain, and all service processes are delivered to smart contracts. As long as the service personnel pass the identity authentication and electronic signature in one department, the smart contracts can be automatically processed and transferred, and the subsequent steps can be completed in sequence. All approvals and signatures. Blockchain invoice is the earliest application of domestic blockchain technology. The tax department launched the "Tax Chain" platform for blockchain electronic invoices. The tax department, the issuer, and the payee join the "Tax Chain" network through unique digital identities, truly realizing "instant invoicing for transactions" and "immediate reimbursement of invoices" - 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 districtBlockchain's non-tamperable and traceable mechanism for data ensures the authenticity and high quality of data, which becomes the basis for all data applications such as big data, deep learning, and artificial intelligence. Finally, blockchain can realize multi-party collaborative data calculations while protecting data privacy, and is expected to solve the problems of "data monopoly" and "data islands" and realize the value of data circulation. In response to the current blockchain development stage, in order to meet the blockchain development and application needs of general business users, many traditional cloud service providers have begun to deploy their own BaaS ("Blockchain as a Service") solutions. The combination of blockchain and cloud computing will effectively reduce enterprise blockchain deployment costs and promote the implementation of blockchain application scenarios. In the future, blockchain technology will also play an important role in many fields such as charity, insurance, energy, logistics, and the Internet of Things.

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

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

Currently, blockchain technology is mainly used in e-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 during the real-time solidification process. 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 does notIt cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, they can provide users with real-time and reliable confirmation solutions.

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

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

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

Facilitate transaction data sharing and transaction witnessing

Facilitate transaction data Share

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

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

Blockchain-based transaction witness

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

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

Promote the rationalization of electronic guarantee rates

Promote financial services and corporate financing for bidding companies

Promote the rationalization of electronic guarantee rates

At present, electronic bidding deposit guarantee 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. Converging multiple transactions through blockchain technologyFor bidders, historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidder's credit in the bidding sub-sector.

Solve the financing problems of successful bidders

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

Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data credibility 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 possible to discount and finance. 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; value transfer through the blockchain has greatly shortened the financing cycle; reducing supplier loan costs 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 allLet’s discuss it together and simply use voting or other methods to solve the problem.

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

Decentralization solves problems.

What application scenarios can blockchain have?

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

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

What are the economic applications of blockchain?

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

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

The second type is applied to enterprise operation and management

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

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

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

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

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

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

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

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

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

In the future, as the application of blockchain technology becomes more mature, it will be applied in many industries. , to create a new ecological model based on technological trust

What is blockchain

If you explain blockchain in non-professional terms, blockchain is a place to store data, but it is stored in the blockchain The data is safe and reliable and no one needs to take care of it, so in the Internet, a place where data and information are exploding, having such a place will be like a fairy treasure.

What can the blockchain do?

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

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

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

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

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 15,728.64 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also an expansionAfter construction, the world's largest storage lake is more than four times the size of the Taizhou Storage Center.

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.

⑷Where is ptah company?

London. PtahDao is jointly controlled and operated by London LMR Partners Co., Ltd., New York LMR Financial Management Co., Ltd., Hong Kong LMR Business Information Services Co., Ltd., LMR Financial Investment Management Co., Ltd., Zurich LMR Technology Development Co., Ltd. and PTAH Technology Investment Co., Ltd.

As a decentralized trust investment trading platform incubated by LMRPartners-web3.0 technology laboratory, PtahDAO is the breakthrough of blockchain technology and financial investment. In combination, the DAO governance logic and rules are implemented in depth to realize the concept of inclusive financial services and drive financial innovation. PtahDAO is an asset allocation method that perfectly integrates the three distinctive advantages of decentralized portals, intelligent social nodes, and intelligent networks. It is an important step in the transformation of traditional financial and investment companies towards a three-dimensional layout of blockchain + financial diversified ecology. As the world's first DAO governance asset plan, it is a milestone. Therefore, it is an inevitable trend for PtahDAO to become a hot spot in the asset trust industry.

⑸ What is blockchain technology? What is blockchain? A chain data structure composed of sequential connections, and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism of economic incentives.control and distribution mechanisms, etc.; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, which is the basis of the programmable features of the blockchain; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, so it addresses this issue Four technological innovations:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.

2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security and personal privacy.

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to carry out automated management in some standardized insurance products.pay.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

Blockchain-Network

⑹ Without issuing coins or engaging in ICO, how does Ant Chain trigger the largest industrial on-chain trend?

I don’t know when it started, but the blockchain has become a collection of huge numbers. With trillions of dollars in assets, billions of nodes and hundreds of millions of users, this new technology, which has been born for more than ten years, has become a behemoth in the eyes of the global IT industry and media.

It seems that a person who has not participated in DeFi, has not studied DAO, and has not chatted about web3 in a cafe has become a sin in the career of an Internet person. Just like a British soldier in the 20th century who has never set foot on the mainland; or a Spanish sailor in the 19th century who has never set foot on the Americas, he has not received the generosity God has given to this profession.

In the past June, three interesting things happened in the blockchain world. Perhaps looking back many years later, the milestones in the history of the development of blockchain technology are implicit in it:

The Federal Reserve’s interest rate hike has led to the collapse of many cryptocurrencies, especially those that were regarded as stable coins in mid-May. After Luna was almost wiped out in value, the price of Bitcoin accelerated its decline in June, with the overall price falling by more than 75%;

On June 23, Solana, the world’s most powerful blockchain, posted on social media Shangguan announced that it will launch the web3 smartphone "Saga" and a customized web3 mobile operating system and Dapp application store;

These two major events in the web3 world are considered to be the coming of the "bear market" , a power switch between software and hardware, application bubble and underlying design. The web3 companies that have suffered heavy losses must "change their minds" and start with more pragmatic consumer applications to obtain more real and valuable customers. And this behavior of moving from fiction to reality and continuing to seek value from entities may become one of the ways for blockchain to survive the potential "bear market".

In the context of the above-mentioned blockchain world, the third event seems quite meaningful:

On June 24, China’s largest blockchain technology platform, owned by Ant Group The Ant Chain announced that the scale of its "physical devices" on the chain has exceeded 5 million units.

This is the "first time" that "physical assets" in industrial blockchains have been uploaded on such a large scale globally, and it is also an unprecedented breakthrough in the scale of "physical assets". Before this, no one has ever been able to integrate physical equipment on the chain on such a large scale.operation.

That’s right, 5 million.

How long has it been since you heard numbers like 5 million in technology news in the web3 world? Looking back at the development history of web3, the last time Bitcoin users exceeded 5 million was in 2017; today, this number has exceeded 200 million. In countries like South Korea, the proportion of cryptocurrency users among the total young population exceeds 20%. Even some large DAO organizations and Dapp applications are close to or even exceed this number.

However, the development of blockchain technology on the industrial side is different from that on the consumer side. The latter is "booming" due to the blessing of cryptocurrency, while the former needs to understand the pain points of the industry and advance scenario by scenario. It requires hard work and is more difficult to enter large-scale commercial use.

This time, the first 5 million in this industrial blockchain can be said to be a milestone number. This means that the physical assets on the chain have passed large-scale verification - a new door to the blockchain has opened.

Lonely Industrial Blockchain

First of all, the industry has very high requirements for segmented scenarios, which means that it is difficult for service providers to meet them with the same set of standardized technical means. All needs from all walks of life. Whether it is DeFI or DAO (Note: Decentralized Autonomous Organization), a general technical model can be used to cope with large enough demand scenarios.

But for industrial blockchains, sometimes customizing a specialized industry scenario requires a lot of time and energy. Take the cooperation between Ant Chain and Chery as an example. Due to the demand for device memory and bandwidth, Ant Chain needs to compress the memory resources of the code from 300KB to 1.5KB in order to meet the requirements of the "car chain".

This kind of "perverted" code optimization demand at the level of "stuffing an elephant into the refrigerator" is unimaginable for developers such as blockchain currencies. This can also illustrate from the side how difficult it will be to achieve universal cross-chain and cross-device interaction in industrial blockchains.

Secondly, the industry has extremely high requirements for the safety, stability, and economy of the chain. This was almost an "impossible triangle" in the past.

Taking Bitcoin as an example, in order to maintain the continuous stability and reliability of the Bitcoin world, major mining farms around the world consume more than 149 terawatt-hours of electricity every year for this encryption system of 21 million currencies. If Bitcoin were a country, its electricity consumption would be comparable to Vietnam, which would rank roughly 25th in the world, equivalent to the power generation of 1.5 Three Gorges Dams. If the social electricity price of 8 cents per kilowatt hour is shared equally in my country, the cost would be 120 billion yuan a year.

For Bitcoin, as long as someone pays the bill, the game can continue. But for industrial blockchain, it is impossible to find any market entity to pay for such crazy operation and maintenance costs.Even if there is, it is not in line with the social responsibility of industrial carbon reduction. Rigid cost-benefit is a red line across the industrial blockchain.

In addition, the industry is also very cautious about encryption requirements. This is a very heavy trust, because the blockchain means a decentralized counting method. Once the system is breached by malicious hackers, it will cause complex losses. The economic model the company builds on this may have holes.

This means that unlike wallets where blockchain currencies are dispersed on different terminal devices, the platform focuses more on algorithms. In addition to strengthening encryption capabilities in terms of algorithms, industrial blockchain companies also need to provide encryption services for a full set of equipment such as information collection & modeling, terminal computing equipment, and information transmission. And every aspect of this is a large, customized project.

Involving complex hardware scenarios is a troublesome matter in itself. Let's take a car as an example. There are interferences caused by complex electronic components inside the car. At the same time, the temperature control conditions of the vehicle components during driving must also be taken into consideration.

In short, the blockchain industry is not on the same level as blockchain currency in terms of actual implementation difficulty or early technology investment costs; but for the platform’s income, there is only one after-sales service. A fraction of that. Everyone knows that using blockchain technology in the digital upgrading of the industry is "technologically practical" and is the right thing to do, but everyone knows better that this is also a difficult thing.

The "Lonely Warrior" in the blockchain

A direct consequence of the difficulty of "industrial blockchain" is that many top talents have flowed to web3. According to statistics, approximately 34,000 developers will join DeFi in 2021, including many employees from leading Internet companies such as Google, Apple, and Facebook who will join full-time.

Compared with the flourishing of web3, the dynamics of industrial blockchain are obviously a bit deserted. On the one hand, many large technology companies look down on these unprofitable "dirty jobs"; on the other hand, start-up teams find it difficult to support the huge sunk costs and expensive market education expenses. In the global industrial blockchain field, there are still no decent unicorns.

However, although the industrial blockchain is full of difficulties, the problems on the industrial side will not disappear just because developers flee.

In many industrial scenarios, blockchain is still regarded as the best solution to break through data barriers in the industry.

Taking the logistics system of commodities as an example, my country has almost both the world’s most segmented manufacturing base and the world’s most complex commodity circulation market. This "complexity" is of course the result of the diversity of retail formats on the one hand, and on the other hand it is also due to the opacity of circulation information. A product's entire link of data from raw materials, manufacturers, distributors, logistics providers, and sales terminals is disconnected, forming fragmented information islands at each node.Every year, major consumer brands spend tens of millions of dollars in consulting fees to obtain very coarse-grained Chinese retail data that comes with heavy labor costs.

After all, no centralized data center can solve such complex data circulation problems, but industrial blockchain can do it.

Or take my country's large energy industry network as an example. The power grid itself is a super-large distributed computing system. Especially since my country has focused on developing distributed photovoltaic power generation industry in recent years, this distributed trend will be more enhanced; on the other hand, on the user side, the emerging consumer network formed by new energy vehicles, battery swap stations, supercharging piles, and batteries is also naturally distributed.

The participating entities and data types are complex. The best way is to use a distributed computing network to cope with the distributed computing power needs.

From the perspective of business common sense, big problems and big opportunities are often equated. Or maybe it comes from the simple philosophy of a Chinese IT person. After all, wherever the problem is, someone has to do it. Although this kind of persistence seems a bit lonely compared to the surging tide of web3, this may be an inevitable necessity. It's probably like a widely circulated famous saying by a certain business tycoon:

"Loneliness is sometimes priceless."

Therefore, there are still many Chinese industrial blockchain companies that are holding on, washing away the halo of valuation myths, and they are waiting for a tomorrow together.

The "Ant Chain" disclosed this time has surpassed the milestone of 5 million physical devices being uploaded to the chain. In fact, it is focusing on the "uplinking" in the new energy industry, covering new energy vehicles, solar photovoltaics, and new energy. Battery and other industries. Establishing a top-level industrial blockchain on the top-level industrial chain may be an important trend in China's blockchain industry in the future.

Obviously, the "Ant Chains" are trying to take over the baton handed to them by the times. When Columbus discovered the American continent, the most people who went to the Americas were trying to colonize and pan for gold; but Columbus himself persisted in exploring Central America and discovered South America on his third voyage.

Columbus may not have been the richest man of his time, but he is a name the world will remember.

Why "Ant Chain"

What many people don't know is that Ant Group has been the largest exporter of patents in the global blockchain industry for many years. On the one hand, Ant Chain does have a strong investment in the blockchain; on the other hand, this is also related to the fact that Ant Chain does have a lot to do.

If you take a closer look at “Ant Chain”, you may be amazed at the company’s all-round and no-dead investment. It almost single-handedly managed to survive the trough of the “industrial blockchain” in The industry alone has planted a big forest. This is probably like what Liu Yu said, "Turning one person into a team."

The place of Ant ChainBeing able to be the first to complete the launch of 5 million physical devices is inseparable from this all-round technical layout capability.

For example, when physical devices are put on the chain, a lot of communication collaboration with IOT technologies will be involved.

As early as June 2021, Ant Chain launched the first batch of wireless communication modules AntChain MaaS, which allows terminal devices to automatically connect to the blockchain through a root of trust based on the unique characteristics of the device and conduct the entire process. encryption. In July, Ant Chain then released the high-speed communication network BTN (Blockchain Transmission Network), which has become a high-throughput, low-bandwidth cost blockchain “highway”.

This technology of trustworthy data on-chain and throughput capability under large broadband conditions have basically made early communication preparations for the subsequent launch of large-scale physical equipment.

However, this is just a small test of Ant Chain’s many technical reserves.

These achievements and innovative technologies were all achieved in 2021 when "industrial blockchain" was ignored by the public. These investments in underlying technology have, on the one hand, helped Ant Chain achieve the first 5 million “physical devices” on the chain globally; on the other hand, it also indicates that 5 million is just the beginning, just like in 2017 Same as Bitcoin.

Therefore, while people are still discussing the bandwidth and scalability advantages of new public chains such as Solana compared to Bitcoin and Ethereum, Ant Chain has already achieved a double billion-level on-chain Capabilities - Support 1 billion account sizes, support 1 billion daily transactions, and achieve 100,000 cross-chain information processing capabilities per second (PPS)

When hackers attack ordinary users' Bitcoin wallets, However, web3 still has no hardware solution, and there is nothing that can be done about it. Ant Chain has redesigned a complete set of industrial Internet encryption systems from system architecture, terminals, and chips.

During this process, the world’s largest blockchain patent exporter has not supported an ICO or issued a single coin. They built the industrial blockchain while standing up.

In fact, the blockchain itself is a thing that creates efficiency based on trust. As Jiang Guofei, the head of Ant Chain, repeatedly told the media, "Blockchain is a deep-seated trust connection technology, (it "'s mission) is to create better links and new value transfers in all walks of life."

This is the first 5 million of the blockchain, but it is a completely different 5 million from the past understanding. It is a door for a group of lonely Chinese IT people to open the future industry.

⑺ What are the relatively mature companies that develop blockchain technology?

Shandong Bianke Information Technology Co., Ltd. is a software development company with excellent technology.

[Blockchain Exchange]

Blockchain technology application research and development, exchange wallet system app development Blockchain technology is actually a new type of Internet. Why is it said to be a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of value transmission. Yuanzhongrui Blockchain System Development Blockchain has many value transfers, such as distributed ledgers, decentralized trust, smart contracts, etc. So what kind of society will it build in the future?

The answer is: a distributed business and self-disciplined society. The first characteristic of blockchain is decentralization; no third-party intervention is required to realize person-to-person, point-to-point transactions and interactions.

Second, the information cannot be tampered with; once the data information is written into the block, it cannot be changed or revoked.

Third, openness and transparency; within a very short period of time, the block information will be copied to all blocks in the network to achieve data synchronization across the entire network, and each node can trace back all past transactions of both parties. information.

Fourth, collective maintenance; in the entire blockchain network, all roles jointly maintain the reliability and security of the entire blockchain information.

Fifth, reliable database; only by mastering 51% of the nodes in the entire system can the blockchain information be tampered with. This is obviously impossible because there are many participants in the entire system and so many nodes are mastered. The cost is extremely high and it is impossible to achieve.

The characteristics of blockchain bring great opportunities to the financial industry. Using it to transform internal application scenarios in the industry can bring three main benefits:

< P>1) Reduce costs: Communication costs: Centralized trading markets generally require the participation and coordination of multiple parties such as central settlement systems, securities companies, exchanges, and banks. The coordination costs are very high. Through the signature encryption next to the blockchain source, etc. Technology allows information to be shared and reduces coordination costs; operating costs: reducing labor and paper vouchers, improving automation through smart contracts, and centralized coordination also bring very high operating costs.

2) Improve efficiency: The settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, it is actually a settlement process that combines clearing, settlement and auditing. The openness, transparency and non-tamperability of the blockchain can save traces of operations, allow supervision records and audit traces to be retained, and facilitate supervision and auditing.

3) Reduce risk: The transaction confirmation on the chain completes the clearing and calculation, greatly reducing the transaction risk. Blockchain technology application research and development, exchange wallet system app development
