❶ New opportunities for blockchain development, the future under the new sharing model

1. After equipped with blockchain, the "new sharing" of computing power candy Power Candy has taken shape< br />
The sharing economy is booming in the Internet environment, but in the current sharing model, "physical sharing" is still the mainstream model, such as shared bicycles, shared charging, shared luggage, shared hotels, etc.

It is true that the contradiction between idleness and lack of physical resources in different projects is the most obvious. For example, people often face traveling without a car or do not want to drive. Therefore, the physical sharing model emerged as the times require. In addition, technological simplicity also allows the most direct application of sharing physical objects to be implemented first.

In fact, blockchain is consistent with the sharing economy in terms of technical applications and business models. The POC computing power candy + sharing economy model launched in 2018 has catalyzed the "new sharing" There is a foundation for practical implementation and a long-term future plan, which may help the new sharing economy get out of the fog and keep the blockchain away from the hustle and bustle.

Based on this sharing model between super nodes and users, POC intends to expand it so that users (including enterprise users), other users and enterprises can share resources. A "new sharing" model to achieve a "new Internet" with resource synergy and maximum energy efficiency.

The key to the problem becomes how to establish mutual trust with the participation of multiple parties, and decentralization ensures that there is no interest control. This coincides with the concept of POC computing power candy. The launch of POC super nodes is undoubtedly the inevitable result of computing power candy realizing "new sharing" with the help of blockchain technology.

Referring to the concept of the white paper, a series of application scenario settings of POC are also in line with the two-way catalytic relationship between blockchain and "new sharing". This may be the reason for the announcement amidst the clamor of blockchain public opinion. The reason why the POC at the meeting was still confident.

2. "New Sharing" + Computing Candy POC Jumps to the Technical Level

First of all, it is the catalytic effect of computing power candy technology on "New Sharing", which is more reflected in On a technical level.

(1) This new sharing feature is actually decentralization, the concept of "weakening platform ownership and strengthening shared management rights", which again coincides with POC computing power candy, using new It is inevitable for technology to achieve new shared decentralization. The principle is that the computing power candy platform does not need to participate in the transactions between users, and these "rights" are owned by the super nodes, and POC has countless nodes, thus achieving decentralization and new sharing by super nodes. Model principles.

(2) "To own but not to possess", both have the same vision of decentralization. There are multiple stakeholders in the new sharing of POC computing power candy, which essentially follows the "own but not possess" characteristic of the sharing economy: all participants can enjoy the resources in the system equally and efficiently, but no one can possess the system. Seek extra personal gain of your own. Each user has the right to become a super node, perform their obligations under the supervision of the entire network, and independently obtain super node benefits.

3. Power Candy + "New Sharing" to realize the Internet of Value

(1) The goal of Power Candy is ultimately to return to how to deliver value . Although when it comes to blockchain, public opinion talks about keywords such as decentralization and trust mechanisms. From the practice of POC, we can also see that these characteristics have obvious technical and commercial value, but in terms of computing power candy For Power Candy itself, decentralization, trust, etc. are all its means to achieve the ultimate goal of the value Internet. This means that the participants in the POC project must transfer value to each other through it rather than traditional information, which has also become one of the criteria for identifying those "pseudo-blockchains".

(2) The combination of POC and blockchain is the appropriate practical field for the value Internet

The value of the value Internet in the computing power candy Power Candy means not only monetary value, Rather, it generally refers to resources that can produce utility. In POC planning, these values ​​realize direct flow, rather than needing to be translated from information into value (for example, WeChat's payment is essentially sending instruction information and then the transfer is executed by Tencent's backend).

In addition to reliable digital currency projects, POC is undoubtedly the most suitable blockchain application field for value flow. According to IHS forecasts, the global installed base of IoT devices will reach 20.7 billion in 2020 and 75.4 billion in 2025. In such a huge network, there are a large number of value (computing power, storage, bandwidth, scenario analysis, identity authentication, payment authentication, etc.) flow requirements.

4. As performance increases and losses decrease, there are more possibilities for new sharing

Whether it is from new sharing to POC computing power candy, or from POC computing power candy to New sharing, both are mutually beneficial processes. In a situation where digital currencies have copied mining models as incentive mechanisms and are widely questioned, the combination of the sharing economy and POC computing power candy shows that blockchain can reversely reduce social costs. Resource consumption, performance improvement paradigm.

No matter what, inNowadays, there are constant disputes about blockchain. Under the new sharing concept, POC computing power candies tied to the sharing economy have given a practical case of blockchain that is not objectionable either at the logical level or at the intuitive level of the public. There will be more in the new sharing. Many applications possible.

❷ How to define blockchain and what are the application scenarios of blockchain

Now many people think Blockchain is a universal technology that can do anything. Blockchain technology is somewhat mythical!
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 (decentralization,distributed characteristics).

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

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

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

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

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

Digital currency

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

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

Digital Government Affairs

Blockchain can make data run and greatly streamline the service process. The distributed technology of blockchain can allow government departments to concentrate 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 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 takes a long time, and it is difficult and costly to obtain evidence. It is extremely difficult to provide evidence 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 cannot replace the original centralized public key encryption technology. The two should complement each other. Through the combination of the two, it can provide users with real-time and reliable Confirmation plan.

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

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

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

Facilitate transaction data sharing and transaction witnessing

Facilitate transaction data Sharing

Currently, the data of different trading centers are not interoperable, and the subject information of different trading centers needs to be repeatedly entered and provided by bidders during the bid evaluation process.There are problems such as difficulty in verifying off-site performance, difficulty in troubleshooting when the same person serves as project manager repeatedly, and low cost of breach of trust by transaction entities. Establishing a cross-regional subject database based on blockchain can well alleviate the above problems.

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

Blockchain-based transaction witness

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

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

Promote the rationalization of electronic guarantee rates

Promote financial services and corporate financing for bidding enterprises

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 to a certain extent improves the performance of most bidders.Guarantee rate.

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

Promote financial services for bidding companies

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

Solving the financing problems of successful bidders

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

Drawing on the supply chain finance model, the bidder is a core enterprise with good credit in government departments, national enterprises and institutions, and the winning contract obtained by the winning bidder as a supplier is considered by financial institutions to be a high-quality asset. Apply for a loan from a financial institution. Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome. Centralized information systems require operators to have strong authority. The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data trustworthiness but also reduces the risk of corruption. 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 transfer part of theOr all the vouchers can be paid to upstream suppliers to achieve discount and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.

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

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

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

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

Decentralization solves problems.

What application scenarios can blockchain have?

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

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

What are the economic applications of blockchain?

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

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

The second type is applied to enterprise operation and management

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

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

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

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

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

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 digital advertising traffic fraud causes losses of tens of billions of dollars every year, there are already blockchain application projects based on digital advertising, such as DCAD, which is based on blockchain. The digital advertising application of blockchain technology mainly solves the problem of traffic fraud

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

What is blockchain

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

What can the blockchain do?

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

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

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

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

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 trading network has changed from a star structure to a point-to-point P2PStructure.

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 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.

❸ Analysis of the relationship between distribution and blockchain

We have already discussed the discussion of blockchain technology in previous articles. I have done this many times, and I have also introduced to you which programming development languages ​​to use to realize the realization of blockchain insight chain technology. Today we will take a look at how to analyze and understand blockchain from a distributed perspective. structure.

Blockchain is the underlying technology in Bitcoin and is used to implement a centerless peer-to-peer cash system. Because there is no central organization involved, Bitcoin uses blocks Organize transaction data in the form of a chain to prevent "double spending" and reach transaction consensus.

Digital assets in the traditional sense, such as game currency, are managed in a centralized manner and can only be transferred in a single system, coordinated by a centralized organization. , usually stored in a database. From a macro perspective, blockchain and database are both used to store data, but the form of data access is different.

The blockchain is essentially a distributed database that is active in different places. The idea of ​​multi-activity in different places was originally to solve the disaster recovery problem of the system. It has been a direction explored in the field of distributed databases for many years, but with little success because multi-activity in different places needs to solve the problem of data conflicts. This problem is actually Not easy to solve. However, the blockchain born in Bitcoin has realized the world's largest remote multi-active database in a completely new way. It is completely open, has no boundaries, supports tens of thousands of nodes and can join and exit at random.

In the areaThe problem of data conflicts in the blockchain is even more prominent. Each node in the blockchain is a completely peer-to-peer multi-active architecture. Tens of thousands of nodes have to reach an agreement. Who should the data be based on? The method adopted by Bitcoin is POW. Everyone comes to calculate a puzzle. Whoever calculates it first has the right to keep accounts. In this cycle, the account he keeps shall prevail. In the next cycle, everyone will recalculate. Nodes competing for accounting rights decide which Quanlu transactions are packaged into blocks and synchronize the blocks to other nodes. Other nodes still need to verify the transactions in the block based on local data, unlike the master-slave nodes of the database. This is the consensus algorithm in the blockchain. Although POW consumes a lot of computing power, the advantage is that in the process of competing for accounting rights, POW only needs to calculate hashes in its own nodes and does not need to go through network voting for election. The cost of network communication is small, and it is suitable for consensus among large-scale nodes. Shahe Computer Training believes that POW is a complete, simple and crude method in the current public chain and can stand the test, but the problem is that the efficiency is too low.

So PoS and DPoS were developed later. Whoever has more assets will have the right to bookkeeping, or everyone will vote, but this also introduces economic problems. For example, the so-called vote-buying issue is difficult to control. In traditional distributed databases, it is not called a consensus algorithm, but a consistency algorithm, which is essentially the same thing. However, the number of nodes in a distributed database is generally very small, and the network is trustworthy. Usually the nodes are safe and reliable. We can basically trust every node. Even if it fails and does not respond, it will never respond. False response. Therefore, in traditional company distributed data, Raft or Paxos protocols are used to implement this consistency algorithm.

❹ How blockchain and zero-knowledge proofs work in the credit system

Zero-knowledge proofs in blockchain play an important role in privacy protection It is no exception in the credit system, but where in the system and in what way it plays a role is a question worthy of thinking and research.

First, credit issues cannot rely entirely on technical reliability. Government authority is sufficient for some issues, such as household registration and identity information. There is no need for further questioning on these issues.

Second, the usage scenario of blockchain evidence storage should be the scenario where there is a long quantitative chain of evidence, such as monthly and annual summary based on flow statistics to ensure that the calculation process of summary is not Fraud. The flow details are in the upstream of the evidence chain, and the time is beforehand. If you falsify upstream, you can falsify months or years in advance. The planning ability of the attacker and the cost of falsification are much higher. To a certain extent, it is economically feasible to prevent fraud.

In fact, this involves the issue of closure of domain events on the chain mentioned above. For cases where it is almost impossible or possibleSeeing that there is no realistic possibility of complete closure in the future, the degree of closure is a gray level issue. If you trace it upstream along the logical chain of events, it will reach a certain level so that the attacker's attack becomes quite or Extremely difficult, blockchain applications will generate value and do not require complete closure. In this way, the value field of blockchain will break through systems that are completely closed on the chain, such as virtual currency and decentralized financial defi, and expand. This logic is not limited to the credit system, but applies to the general logic of combining blockchain and fields. To give another example, whether the traceability system can achieve the anti-counterfeiting function depends on whether the depth of the traceability in the evidence chain is enough to cause the dilemma of the counterfeiter. Without examining this point, it is only a formal use of blockchain evidence. meaningless.

So we can almost get a theorem:

The value level of blockchain in domain applications is directly proportional to the traceability depth of the evidence chain.

Then the second question that follows is: tracing back along the chain of evidence, the further upstream, the closer to the privacy of the subject (citizen privacy or organizational business secrets). The solution to this problem is where zero-knowledge proofs come into play and how they work. The application value of many zero-knowledge proofs is unclear. Now we consider it in the context of the evidence chain and it will become clear:

1. Zero-knowledge proofs are used to process quantitative evidence. During the chain traceability process, traceability is completed without revealing the clear text details of the upstream evidence chain, which not only plays the role of blockchain traceability along the evidence chain, but also protects privacy.

2. For scenarios where traceability is not necessary, the evidence chain does not exist, and the role and significance of zero-knowledge proof are also unclear. For example, for general identity and household registration information, administrative authority should be considered credible and there is no need to trace it back. Note that the evidence chain mentioned here is not a causal relationship in the physical sense, but a value trade-off through system application goals.

To summarize:

1. Use blockchain technology to retain the upstream of the evidence chain. 2. The further upstream the evidence chain is, the closer it is to citizen privacy. Use zero-knowledge proof to protect privacy

1. Refer to zkledger of MIT Media Lab and use blockchain combined with zero-knowledge proof to deal with citizens and organizations Summary reporting issues of financial and taxation processes.

2. The technical problem that needs to be solved is that in the zkledger scenario, there are only a few large transactions of a few banks with a small amount of data, but when used in individual citizen scenarios, the amount of data is huge.Big, need to find ways to solve performance problems.

❺ What are the technological innovations and applications of blockchain

1. Blockchain system

As the underlying technology of Bitcoin, the blockchain system It is generally composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

1. Data layer

The data layer encapsulates basic data and basic algorithms such as underlying data blocks and related data encryption and timestamps. It mainly describes the physics of the blockchain. The form is the chain structure on the blockchain starting from the genesis block. It includes the block data and chain structure of the blockchain, as well as the random numbers, timestamps, public and private key data on the blocks, etc. It is the underlying data structure in the entire blockchain technology.

2. Network layer

The network layer mainly implements distributed network mechanisms through P2P technology, including P2P networking mechanisms, data dissemination mechanisms and data verification mechanisms. Therefore, in essence, the blockchain is a P2P network with an automatic networking mechanism, and nodes maintain communication by maintaining a common blockchain structure.

3. Consensus layer

The consensus layer includes consensus algorithms and consensus mechanisms. The consensus layer allows highly dispersed nodes to efficiently reach consensus on the validity of block data in a decentralized blockchain network. It is one of the core technologies of the blockchain and is also the governance mechanism of the blockchain community. There are currently dozens of consensus mechanism algorithms, including proof of work, proof of equity, proof of equity authorization, proof of burning, proof of importance, etc.

4. Incentive layer

The incentive layer mainly includes the issuance system and distribution system of economic incentives. Its function is to provide certain incentives to encourage nodes to participate in the security of the blockchain. Verification work, and incorporating economic factors into the blockchain technology system, incentivizing nodes that abide by the rules to participate in accounting, and punishing nodes that do not abide by the rules.

5. Contract layer

The contract layer mainly includes scripts, codes, algorithm mechanisms and smart contracts, and is the basis for blockchain programmability. It embeds code into the blockchain or token, and can implement customized smart contracts. When certain constraints are reached, it can be automatically executed without going through a third party, which is the basis for trustless blockchains.

6. Application layer

The application layer encapsulates various application scenarios and cases, similar to applications on computer operating systems, portals on Internet browsers, search Engine, e-mall or APP on mobile phone. It deploys blockchain technology applications on Ethereum, EOS, QTUM, etc., and implements them in real life scenarios. In the future, programmable finance and programmable society will be built on the application layer.

The data layer, network layer, and consensus layer are necessary elements to build blockchain technology. Without any layer, it cannot be called blockchain technology in the true sense; incentive layer, contract layer, and application layer It is not a necessary factor for every blockchain application, and some blockchain applications do not completely include this three-layer structure.

From a business perspective, blockchain technology has its own characteristics, that is, it is sufficiently digital, it is cross-border, cross-time and space, and cross-organization. The flow of data has no boundaries, so the blockchain is distributed at the same time, it is self-organized and decentralized.

So the origin of blockchain and the application of any new disruptive technology have always had two routes, or two methods. One way is to regard it as a tool and use it to improve the traditional business model and obtain an improvement in marginal benefits. The other is to treat it as a system to reconstruct the underlying logic of business.

There is a good example of these two application methods in the past few years. When Internet companies are promoting "Internet+", we also see many traditional business organizations saying that it is not "Internet+", but "+Internet". So where are those people who shout "+Internet" now? Some people think that the Internet is just a technology used to improve traditional things, and some Internet technologies can be added to traditional things. For example, if you use the Internet as email, you build an email system and think it is the Internet. But some people treat the Internet as a system and reconstruct the business from the bottom up. In the end, you will find that you are unemployed.

The second is decentralization. Why go to the center? Regional center technology in business has brought about business decentralization, which is an inevitable trend in history. Where is this trend? I think there are two points. One is economic globalization and entering version 2.0. Now through the Internet, it is no longer the company that is globalizing, nor the company turning itself into a multinational company, but the Internet is empowering any individual, so that it can sell its products through the Internet in a small county in China. worldwide. When economic globalization develops to personal globalization, solving point-to-point transactions and point-to-point services becomes a prominent issue. Then the real-time clearing and settlement and point-to-point transaction settlement brought by blockchain technology can just help the globalization of personal business activities.

The third is the digitalization of the economy. When data is collected to a certain extent, its circulation is basically across time and space. The demand for financial payments from commercial activities is carried with them anytime and anywhere, but it is impossible to provide scenario-based and virtualized payment settlement anytime, anywhere and on demand. Services will eventually be eliminated by technology and the market.

❻ An introduction to the principles and applications of blockchain technology

1 , Blockchain is a string of passwords usedThe data blocks generated by the correlation of cryptographic methods. Each data block contains the information of all Bitcoin network transactions in the past ten minutes, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block. It is the underlying technology of Bitcoin, like a database ledger that records all transaction records.

2. Broad definition: Use encrypted chain structure to verify and store data, use distributed node consensus algorithm to generate and update data, use automated script code (smart contract) to convert and operate data A new decentralized infrastructure and distributed computing paradigm.

3. Narrow definition: A decentralized shared account that combines data blocks into a specific data structure in a chain in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable.

4. Characteristics of blockchain: Decentralization: The verification, accounting, storage, maintenance and transmission of blockchain data are all based on distributed system institutions, using pure Mathematical methods rather than central structures are used to establish trust relationships between distributed nodes, thereby forming a decentralized and trustworthy distributed system.

5. Time series data: Blockchain uses a chain block structure with timestamps to store data, thereby adding a time dimension to the data and having strong verifiability and traceability.

6. Collective maintenance: The blockchain system uses a specific economic incentive mechanism to ensure that all nodes in the distributed system can participate in the verification process of data blocks, and select specific nodes through a consensus algorithm Add new blocks to the blockchain.

7. Programmable: Blockchain technology provides a flexible script code system to support users in creating advanced smart contracts, currencies or other decentralized applications.

8. Safe and trustworthy: Blockchain technology uses asymmetric cryptography principles to encrypt data, and at the same time uses the powerful computing power formed by consensus algorithms such as workload proof of each node of the distributed system. To resist external attacks and ensure that blockchain data cannot be tampered with or forged, it has high security.

9. Blockchain application scenarios: Digital currency: Represented by Bitcoin Damin Coin, it is essentially a digital currency generated by a distributed network system. Its issuance process does not rely on a specific centralized institution. .

❼ Application of blockchain in the financial field

1. Application and development of blockchain

Some Internet, Internet start-ups and traditional financial industries Started to try out applications in some projects

2. Domestic financial institutions are testing the waters of blockchain

Various financial institutions are testing the waters one after another, and they are basically at the stage of conceptual implementation.It is in the experimental stage and has not yet been commercialized on a large scale.

3. Panoramic view of blockchain application in the financial field

4. Ghostwriting

5. Digital bills

Bills are an important financial product in the financial market. They have dual functions of payment and financing. They are of high value and bear bank credit or commercial credit. Once a bill is issued, its face amount, date and other important information cannot be changed. Bills also have circulation attributes and can be accepted, endorsed, discounted, rediscounted, collected and other transactions within a specific life cycle. Once the transaction is completed, the transaction cannot be revoked. There are two characteristics in the circulation of bills: First, the circulation of bills mainly occurs through bank acceptance bills, and the number and circulation of commercial acceptance bills are small; second, each bank independently conducts credit granting and risk control on the bill business, and a single bank's Risk control results may affect other participants in the bill market transaction chain.

The experimental production system of the digital bill trading platform uses SDC (Smart Draft Chain) blockchain technology to protect privacy through cryptographic algorithms such as homomorphic encryption and zero-knowledge proof. The Byzantine Fault Tolerance Protocol (PBFT) performs consensus and uses a see-through mechanism to provide data monitoring.

The experimental production system includes four subsystems: stock exchange, bank, enterprise and monitoring: the stock exchange subsystem is responsible for managing the blockchain and monitoring the digital bill business; the bank subsystem has Digital bills have business functions such as acceptance and receipt, discount signing, rediscounting, and collection and repayment; the enterprise subsystem has business functions such as issuance, acceptance, endorsement, discounting, and prompt payment of digital bills; the monitoring subsystem monitors the status of the blockchain in real time and business happenings

❽ The most comprehensive coverage! Sorting out the direction of Web3.0 venture capital and talent demand

1. Web3.0 key entrepreneurship/investment directions

Web3 will be a huge paradigm change, which breeds many entrepreneurship and investments Opportunities, such as:

1. Blockchain

Web3 needs blockchain technology to support the vision of users fully owning information digital assets. Blockchain as the underlying technology will be The biggest entrepreneurial opportunity in the Web3 field. It is no exaggeration to say that the market size of the public blockchain will exceed that of all current Internet companies, because Google, FaceboLogically speaking, ok is just an application running on these public protocols. Just as all Internet companies need to run on the TCP/IP protocol, all social networks and information searches in the future will run on the underlying blockchain protocol. superior.

Representative companies: Ethereum, Solana, Avalanche, NEAR, Polkadot, Cosmos.

2. Decentralized identity system

Today’s Internet companies own everything of users. Users are forced to register their own accounts with every company. The valuation of companies is based on ownership. How many users and how much advertising revenue is generated using user data. In the Web3 era, users will completely own their own information, and owning their own information starts with owning their own identity.

In the technical architecture of Web3, users will pay operating fees for access and use of the website, so they should have the rights to their own data. In the future, everyone will have a domain name and a webpage located on the decentralized IPFS.

Theoretically, there is no need for multiple coexisting DID systems in Web3.0. However, for various reasons, different blockchain ecosystems have different DID systems, and a unified DID system will not appear in the short term.

In this case, an identity aggregation project that can be compatible with and integrate most DID standards will bring great convenience to users. The identity aggregation project supports connecting users' DID identity information across multiple ecosystems, helping users view, manage and aggregate identity information on different blockchain networks. At the same time, identity aggregation projects can also be combined with data index projects, application projects, etc. to further play a role.

Representative company: ENS.

3. Storage and access of distributed data

In the Web3 era, users have their own data and need to pay for data storage. For example, NFTs purchased by users need to be stored somewhere where they can be permanently accessed. In addition, convenient access requires the provision of data transfer and indexing services.

Representative companies: Filecoin, Arweave, The Graph, Livepeer, ByteTorrent.

4. Communication protocol

Due to technical limitations, different application scenarios will require different blockchain technologies. Different blockchains need to communicate with each other and are located in a Smart contracts on a blockchain may need to call contracts on another blockchain, and digital assets located on one blockchain may need to be loaned to another blockchain.

Representative companies: XCMP, EPNS, XMTP.

5. Resource allocation optimization protocol

With the advent of the cloud computing era and digital information technology deeply changing industry and agriculture, more assets are digitally reflected, and various tokens represent not only Includes only computing resources, storage resources, and may also represent digital assets as well as physical world assets. Finance, as a scientific theory of value exchange across time and space, will be applied to distributed network collaboration.

Decentralization and personal ownership of digital assets in the Web3 world require the collaboration of network resources.

Representative companies: Uniswap, Compound, AAVE

6. Social network protocol

In the Web3 era, since there are no intermediaries, decentralized users need more An open social network protocol is used to contact users. The user's identity value does not have the intermediary Facebook, and it is more necessary for the user to build a social network to reflect his own value.

Representative companies: Context, CyberConnect, DESO, RSS3

7. NFT

In addition to digital artwork, NFT’s greater role should be a programming unit.

If smart contracts are classes in object-oriented programming, then NFT is the Singleton in object-oriented programming.

8. Wallet

Just as the user interface of Web1.0 and Web2.0 is a browser, the wallet will be the browser of Web3.0, hosting the management of user information and access to DApps function.

Representative companies: Argent, MetaMask

9. Shared network

The debate about whether the Internet is centralized has never stopped, and whether the network should be neutral No conclusion. But with the development of mobile devices and sensors, we have the opportunity to build a shared wireless network. Just like the P2P network, the users of the network are also the service providers of the network. Different from P2P, the emergence of tokens can provide settlement between users and providers.

Representative companies: Helium, DIPNET

10. Content Creation Economy

In the Web3 era, users have their own creative content and their own readers, and will no longer rely on platforms A charging model that distributes traffic and advertising fees.

Representative company: Mirror

11. On-chain data analysis

p>

Accurate data analysis can reconstruct the business model of blockchain projects. In this process, technologies such as DID and privacy computing will play an important role in privacy protection and other aspects.

As the number of blockchain users increases, the volume of data on the chain increases exponentially. These data play an important role in analyzing user portraits. Accurate data can provide reliable data input for other projects, thereby completing the industrial restructuring and upgrading of other projects.

Through accurate data analysis, effective data such as on-chain credit can be obtained, thereby expanding different application scenarios. Take DeFi projects as an example. Currently, many DeFi projects use mortgage lending instead of credit lending, and low fund utilization has always been a problem that plagues many DeFi projects.

If there is accurate on-chain data as input, credit will be introduced into the chain based on past data, and the indexing and aggregation of user-related data such as identity, credit, user portraits, etc. in the Web3.0 system will be provided. , accurately screening users, then credit loans or unsecured loans can be implemented for users with higher credit, greatly improving the utilization rate of user funds.

12. Privacy enhancement technology

Currently, users do not pay enough attention to identity and account information on the blockchain. They leave more and more public information on the chain, which can be accessed by everyone without permission, posing security risks.

In Web3.0, people will be more aware of data and privacy protection. Users no longer want to sacrifice privacy for convenience. The current model cannot meet Web3.0's privacy protection requirements. need. Especially after the rise of DeFi, many users do not want their transactions on the chain to be monitored by others.

Privacy enhancement technology can solve the confidentiality and privacy protection issues of transaction information and restrict unauthorized users from accessing transaction information. Privacy-enhancing technologies enable secure sharing, aggregation and analysis of data without compromising security and privacy.

13. Web2 and Web3.0 middleware

At present, a large number of users are still concentrated on centralized platforms, and they have become sticky and formed user habits for these platforms. Middleware projects can serve as a bridge to help users migrate from Web2 to Web3.0. By developing a series of tools on the Web2 platform, users can send encrypted information and digital currencies on a familiar platform, lowering the threshold for users to use Web3.0 projects.

2. Key employment directions of Web3.0

1. Network maintainers

Whether it is the POW or POS era, network operation and maintenance will be more distributed type of device/node. About network maintainers, from Bitcoin miners to EthereumFang Miner and Filecoin Miner are the most well-known. Network maintainers shoulder the important task of maintaining infrastructure security and fairness and will play a role in the next generation of Internet, Internet of Things, edge computing, and 5G.

2. Community Manager (Moderator)

Community manager Moderator, referred to as MOD, is an essential profession in Web3.0 and is required by NFT, Gamefi, Defi, and DAO projects. Relevant personnel manage the community. MOD is usually held by the most active community members, but it is not ruled out that the project party recruits through outsourcing. MOD has become the most competitive profession in the industry because of the opportunity to participate in the profit sharing of early teams.

3. Artists

Since the development of NFT, hundreds of artists and studios such as Beeples, Yuga Labs, Fang Lijun, etc. have released NFT works. Among them, NFTs sold by top artists and celebrities are very popular. NFT skips traditional middlemen such as galleries and auction houses and provides artists with new ways to monetize.

4. Metaverse Architect

Since the development of virtual world projects such as Sandbox, Decentraland and Crypto Voxel, there has been an increasingly strong demand for companies in the real world to build virtual headquarters. Metaverse architect has also become a cutting-edge profession.

5. Game Designer

Virtual world projects such as Sandbox, Decentraland and Crypto Voxel are essentially UGC platforms. Game designers can not only create their own NFTs on the platform, but also participate in the design of maps, levels and battle modes in games on the platform, and have their own voxel games.

Six. Game Players

In some chain game industries, gold miners and gold mining guilds have become a very important part of the ecosystem. Since chain games are classified into different categories, some are more money-oriented and some are more game-oriented, their game player groups are also very different. Axie Infinity players need to purchase relatively expensive game assets to make gold, so the guild pays and players contribute, which became an early P2E model. In Sandbox and Skyweaver, only players with smooth operation and rich experience can obtain gold rewards.

7. Defi/Cefi miners

Defi/Cefi miners refer to groups that flexibly allocate funds to Defi protocols/centralized exchanges to earn income. They often have insight into Defi product model and security, and can discover new protocols with the highest profitability immediately, commonly known as head-mining. The behavior of Defi/Cefi miners has gone far beyond personal investment and requires systematic research and keen industry acumen.

8. Blockchain-related development, product, and research positions.

Blockchain is the core infrastructure of Web3.0. Most of the current recruitment for Web3.0 in the market are basically related to blockchain.
