⑴ How to treat the hot topic of blockchain rationally
The blockchain 1.0 era is represented by digital currency, mainly Bitcoin, and blockchain 2.0 is based on intelligent Represented by contracts, it is a derivative of certificate technology;
Blockchain technology is just an underlying technology with unlimited value, but after all, Bitcoin is limited, so digital currencies have derived many other currencies; but due to the intermediate The mechanism is not perfect, there is no innovation, and scams such as currency speculation appear. The real blockchain technology should not be a means of currency speculation, but its application in all walks of life, not only in the financial field, but also in supply chain management, Intelligent manufacturing, culture and entertainment, financial services, medical health, IP copyright, education, Internet of Things, sharing economy, communications, social management, charity, social employment, and e-government can all be widely used.
At present, the blockchain 3.0 era has arrived. The collaborative operation model of blockchain can be seen behind the operation of all walks of life. Therefore, blockchain will definitely change human life extensively and profoundly. Therefore, the entire Life services will enter the blockchain era. In this Internet development process, blockchain + physical industries, blockchain e-commerce, and blockchain community operations can all apply blockchain technology.
⑵ If college students want to get in touch with blockchain, where is the best place to start?
If you just want to get in touch, then I suggest you use the following method (mainly for novice students in non-related majors, (Excluding friends who are preparing to work in the blockchain industry)
First of all, if you pay attention to this issue, it means that you have great curiosity or strong interest in blockchain, then, I don’t recommend that you start reading the highly professional “White Paper” directly, because the large number of professional terms and nouns can be overwhelming.
In another way, let’s think from the perspective of young people. Before learning blockchain knowledge, we should start with the most basic understanding.
1. On the DouYin platform with huge traffic, if you enter “blockchain” in the search box, many “famous” teachers will appear to explain to you what blockchain is with vivid and short videos. . Although the video content cannot be said to be 100% correct, it is completely sufficient for a simple basic understanding. After all, "There are a thousand Hamlets in the eyes of a thousand viewers. Everyone will have a different understanding and view of the blockchain, and you will also have a different view in the future.
2. You now You may have a little knowledge of blockchain or just have an outline. So, please take your impression and read "100 Questions on Blockchain" (you can search it directly on the Internet). It is still a very short video, but Basically, blockchain-related knowledge is covered, including cryptography background knowledge, the history of blockchain, what is blockchain, introduction to Bitcoin and Ethereum, application scenarios of blockchain technology, etc.
Note, you don’t need to study every noun in detail, just browse them all to distinguish between those you understand and those you don’t understand.
3. In your spare time, you can read the online novel "Blockchain Cultivation", which is probably a story about a leek soul that travels through time and obtains the blockchain system for cultivating immortality, cheating on life, and starting from mining. In this novel, you will see a lot of nouns (miners, nodes, digital currencies, blockchain systems, etc.). Bringing the knowledge you have learned previously into the book will work wonders.
Excerpt - "All the heavens and worlds have actually condensed into a huge blockchain... Everyone can do it through the blockchain... All that is needed is virtual currency. We Use your own mana essence...sacrifice to the blockchain...and you will get virtual currency, which can replace currency in reality, buy and sell everything, and even use the blockchain to directly practice, from the blockchain Internet of Things Obtain elixirs and exercises."
Seeing this, do you think it is more interesting than the "White Paper".
4. It is recommended to review "100 Questions on Blockchain" and then read "Bitcoin White Paper".
5. If you are facing an internship, you can go to relevant companies to experience it and apply what you have learned.
6. Of course, following Coin Secretary is also a good choice

⑶ New ways to track and manage digital assets, teach you how to learn View blockchain bills
Bills record value circulation and status, which are the basic functions of financial services.
Our commonly used banks, Alipay, WeChat Pay, etc. will record a transaction for ordinary users and merchants, and provide query, statistics and analysis services in different dimensions.
For example, the Alipay annual bill that everyone loves to post will count the user's total income and expenditure throughout the year, consumption types, Yu'E Bao and other financial management income, and the number of takeaway orders. Through big data technology, consumer interests and trends in various regions and different age groups are displayed, so that consumers can better understand the consumption environment around them, and merchants can grasp market demand in a timely manner.
In a decentralized blockchain network, transactions are permanently recorded on the chain, open and transparent, and accessible to everyone.
However, since the design of the blockchain is more inclined to ensure non-tampering and data compression requirements, the filtering query function at the business level is missing. Coupled with the different rules of different chains, it becomes extremely difficult to track and manage crypto assets. This is why digital asset investors often lament that they “always feel like they don’t have a clear account.”
SixPencer launches a new blockchain accounting artifact, which currently supports asset tracking and management at the bottom of Bitcoin and Ethereum. It is free to use and does not require registration.
Once launched, it has been welcomed by miners, asset management institutions, OTCA favorite among merchants, crypto startups, and digital asset investors.
As a professional asset management tool, it can not only query all transaction records on the chain, but also view account balances and It holds assets and provides daily income and expenditure status of various currencies, supports single or multi-address aggregate income and expenditure statistics, address portrait analysis and charts, large transaction record rankings, contact management, etc.
After entering the website, enter the Bitcoin or Ethereum address in the search box on the homepage, and click Search to enter the overview page of the address.
We use the address that currently ranks first in ETH holdings on the entire network: (tag: bitfinex 1) account as a demo account for demonstration, and all data are real on-chain data.
Here is a brief introduction to the difference between addresses and bank accounts on the blockchain. On the blockchain, an address is similar to a bank card number. Knowing the address is the same as knowing the bank card number, and you can transfer money to it.
But the difference is that the blockchain is a distributed public ledger that cannot be tampered with. It is usually anonymous and anyone can conduct public queries on any address. The bank account can only query your own account information, and you cannot know other people's account information through the bank card number.
If the user has multiple addresses or wants to track other addresses, they can search. All searched address information will be summarized on the asset portfolio page. Click the drop-down box to switch or delete accounts.
In addition to the basic information provided by the blockchain browser, SixPencer also adds and displays some personalized indicators to help users understand their own on-chain portrait and track the on-chain trajectories of other accounts. On the overview page below, you can view the address's asset overview, historical indicators, income and expenditure statistics, and asset holding information.
Address overview
Creation time: date of first receipt of ETH
Net assets: all assets, including ERC20 tokens Total USD value of assets
ETH ranking: Ranking of ETH holdings among all Ethereum addresses
p>
ETH balance and valuation: the amount of ETH held and its corresponding dollar value
Historical indicators
Historical indicators display transaction volume, number of transactions, tokens Coin analysis and contact analysis are four major dimensions. Through statistics, the unclear and confusing accounts can finally be settled. For example, the simplest accounting calculation, total ETH income = ETH balance + total ETH expenditure + total ETH handling fee. Another example is the total number of transactions = the number of transfer-in transactions + the number of transfer-out transactions.
Due to the particularity of the Ethereum network, all transfer fees are paid in ETH. Therefore, we list the handling fees separately, and also support separate screening of handling fees in the transaction details to help users count handling fee expenditures.
Some interesting data, the demo account fee is 1.1556ETH, a single large ETH transfer reaches 900,000 ETH, and the number of tokens held is There are 350 types, and the most traded token is USDT, with only 37 addresses that have been traded with it.
Generally speaking, addresses holding hundreds of different assets are usually exchange addresses. In addition, the number of transactions and contacts are not many, so it can be ruled out that it is an external address, and it can basically be judged that it is used internally by the bitfinex exchange. address.
Income and Expenditure
Statistics of the total income and expenditure of all assets this month, including handling fees.
Asset holdings
Displays the number, value, asset price and 24h increase or decrease of assets held. The address of an exchange such as a demo account, which holds assets, usually does not fit on 10 pages.
In addition to providing the transaction flow of addresses, SixPencer also supports query and filtering of full historical transaction records, balance information, daily income and expenditure statistics, etc.
Transaction details
From the following page, you can clearly know the income and expenditure of ETH assets this month. Users can also filter based on date, fund flow, transaction classification and labeling system. If you need more detailed statistics, we will introduce how to filter transactions at specified addresses later.
Click the ETH drop-down box in the picture above to switch to the transaction details page of other currencies. For example, switch to the transaction details of USDT to view the detailed status of USDT.
In addition to monthly bills, SixPencer displays the transaction details of each transaction, providing information such as transaction direction, transaction counterparty, transaction amount, account balance, transaction time, daily income and expenses, etc. As you can see in the picture below, the nearly 6 ETH transactions were all transferred from the bitfinex 3 account to bitfinex 1.
Transaction details
Click on any transaction details to enter the transaction details page of that transaction. The transaction hash is a unique and immutable transaction ID for each on-chain transfer, similar to the concept of an order number.
The specific information of a transaction can be queried through the transaction hash.
The transaction quantity, transaction status, transaction time, sender and recipient, handling fee, etc. shown below are the specific information of this transaction and will not be repeated here. It is worth noting that SixPencer provides a personal tag and remark system. Users can make personalized classifications and notes for individual transactions to help remember and not forget every transaction.
How to quickly find and specify the transaction information of the address?
As time goes by and the number of transactions increases, it becomes extremely complex and difficult to query the specified transaction information on the chain. SixPencer refines the transaction information according to business needs and provides a tag system to assist users in customization. Transaction inquiries and statistics.
For example, you want to query the total amount of ETH transferred to the demo account from the address (label: bitfinex 3) in June 2020. Through our billing system, it only takes two steps to check.
1. Label: For demonstration, we will rename the label "bitfinex 3" to "test test".
2. Filter: Filter the dates to June 1st - June 30th, select "Transfer" in the filter bar, select "Test" in the bottom tab bar, and click Save.
After saving, you can search for all the transaction information transferred to the demo account from "test" in June. As can be seen from the picture below, in June, the demo account received a total of 58,440.2489 from the address labeled "test" ETH.
If the user wants to query transactions with multiple specified addresses, select multiple tags and adjust the date, fund flow and other information to perform automatic statistics of assets.
In the analysis column, users can query the chart analysis information of the address in different dimensions, including the four major dimensions of balance, transaction, classification and ranking. You can also view more detailed data and charts by clicking on each dimension separately.
Balance: Balance displays the balance quantity and value trend of assets
Transaction: Transaction displays all transactions, the number of transactions transferred in and out, and the number of transactions Trends in value and number of transactions
Classification: Classification counts transaction types based on the platform's address label system, reflecting the transaction preferences of the address
< p>
Ranking: The ranking displays active contacts according to the number of transactions, and displays large transactions according to the transaction amount
For example, ranking Analysis, you can quickly check the specific transaction amount and large-amount transfers with a certain address. As shown in the figure below, the demo account and the address labeled "test" have a total of 177 transactions this month. Other transactions with the demo account that have more transactions are ERC20 Token contract call transactions.
From the picture below, the large-amount rankings are also transaction information with the address labeled "test". The table displays the transaction object, transaction time, transaction direction, transaction quantity and value. If you are interested in large accounts on the exchange, you can check the large transfer information of the exchange address to see which addresses are large deposits and withdrawals.
The address book displays all addresses that have transaction records with the demo account. In addition to the platform's own label system, users can add labels to addresses or rename labels.
Tags: tags known by the display platform tag system and tags added by users
Recent contacts: Show recentAddresses/labels with transaction records in the past 30 days
All contacts: Displays all contact addresses/labels with transaction records and the number of transactions More than 10,000 addresses, get the contact display of the last 10,000 transactions
In summary, SixPencer’s new asset tracking and management tool can provide better performance than the blockchain browser Or the wallet’s more comprehensive query and analysis functions. As a tool product, it is intended to assist users in digital asset management and help everyone make better decisions through further analysis of user profiles on the chain.
We believe that the open and transparent mechanism of blockchain should make data query easier, but currently it is still difficult and painful to quickly query blockchain data according to actual business needs, and has become a major obstacle to commercial implementation.
Digital asset transactions are only a small part of it. A large amount of valuable data will be stored on the blockchain in the future. SixPencer will continue to launch more practical tools to allow Data better serves the business.
⑷ A brief discussion on the accumulation of blockchain storage and traffic technology - the era of real WEB3 is coming
Modern society’s focus on storage and traffic technology What breakthroughs and advances have been made? Let’s briefly summarize it for you.
The current Internet is all about centralized traffic and storage. With the development of the world, the bt network was born. The bt network is a distributed storage and traffic system. But it also has its limitations. First, the bt network can only transfer and share single files. Second, the bt network does not have an incentive mechanism. To put it simply, everyone joins the bt network, but there is no willingness to actively save or distribute files, because this is not beneficial to the participants.
With the exposure of bt network flaws, IPFS was born. That is, the IPFS system developed by the Filecoin project party’s protocol laboratory. IPFS is an upgraded version of the bt network. It adds a folder system based on the bt network. In the IPFS system, folders can be transferred and shared directly. Others can also browse related data, files, etc. directly from the folder.
But IPFS, like the bt network, has several problems. First: There is no incentive system. Second: In the early stage of file transmission, because there are very few nodes to store files, the efficiency is very low. For example, if A uploads a file and B needs to retrieve it, it can only retrieve it from A. Therefore, the efficiency is very low. If C wants to retrieve, it can only retrieve from the two nodes A and B. If both A and B are shut down, the files will not be retrieved. This is how IPFS and bt network existThe problem is that their initial transmission efficiency is extremely low. Only when files are retrieved countless times and widely distributed among nodes, the transmission speed will become very fast. So the bt network and IPFS system are both a process from slow to fast. If you retrieve a file that is distributed less among nodes, the retrieval capability is very weak and the transmission speed is also very slow. In order to solve this incentive mechanism problem, Protocol Labs developed the Filecoin supply chain.
Filecoin and IPFS are two concepts. Filecoin actually puts the real-life IPFS onto the blockchain. The characteristic of blockchain is decentralization, and nodes do not trust each other. Data transmitted between nodes must be re-checked. This results in very poor performance of the blockchain. After IPFS was put on the chain, Filecoin was formed. Therefore, Filecoin is also subject to the impact of blockchain performance, resulting in the inability to match valid data and the inability to perform efficient retrieval. Filecoin realizes the storage of data on the blockchain, which is a very significant contribution. Subsequently, SWARM and BZZ appeared, but BZZ has no block incentive mechanism and only has a traffic settlement system, which currently seems to be a failure. However, BZZ has also made certain improvements compared to IPFS and Filecoin: a set of active distribution mechanisms. For example: when I upload a video, the video will be actively distributed by the node. The video will be quickly cached to multiple nodes. Therefore, BZZ has made outstanding contributions in traffic settlement and efficient retrieval. Although it left behind technical contributions, it remained a failed project.
From the current point of view, most of the problems in traffic and storage have been solved in the blockchain field. The second is the issue of blockchain performance. After years of evolution, Layer0, Layer1, and Layer2 have also undergone continuous experiments. In recent years, research in the field of Layer 1 has achieved a lot of results and patents. I believe that breakthroughs in high-performance public chains will appear soon.
Therefore, if you want to build a blockchain network that is truly similar to web3, you should achieve breakthroughs in three aspects: First: efficient retrieval. Second: Incentivize storage and traffic separately. The third is that there must be an authorized access system. The authorized access system is similar to when people watch video websites and need to pay to obtain data. In the traditional Internet world, there are many monetization channels. The Internet world of blockchain has just taken shape. Therefore, ecological builders can directly obtain certain benefits. Only in this way can the prosperity of the ecosystem be promoted, and the builders of the ecosystem can continue to contribute more useful applications. Finally, the breakthrough of high-performance public chains is also an indispensable part. Therefore, with the above four conditions, web3 is getting closer and closer to us.

⑸ How to define blockchain and what are its application scenarios
Many people now think that blockchain is a 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 (decentralized, distributed characteristics).
At the same time, those 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 kind of data blockDistributed ledger (database) technology that sequentially connects and cryptographically ensures that it cannot be tampered with or forged. In layman's terms, blockchain technology can achieve openness, transparency, non-tampering, non-forgery, and traceability of all data information in the system without the need for third-party endorsement. As an underlying protocol or technical solution, blockchain can effectively solve the problem of trust and realize the free transfer of value. It has broad prospects in the fields of digital currency, financial asset transaction settlement, digital government affairs, and certificate deposit and anti-counterfeiting data services.
Digital currency
After experiencing physical objects, precious metals, banknotes and other forms, digital currency has become the development direction of the digital economy era. Compared with physical currency, digital currency has the characteristics of easy portability and storage, low circulation cost, convenient use, easy anti-counterfeiting and management, breaking geographical restrictions, and better integration.
Bitcoin technically implements an electronic cash system in which both parties to the transaction can directly transfer funds to each other without the need for third-party transfer or arbitration. In June 2019, the Internet giant Facebook also released a white paper on its cryptocurrency Libra. Whether it is Bitcoin or Libra, the underlying technology they rely on is blockchain technology.
my country began the development of central bank digital currency as early as 2014. my country's digital currency DC/EP adopts a two-tier operating system: the central bank does not directly issue digital currency to the public. Instead, the central bank redeems the digital currency to various commercial banks or other legal operating institutions, and then these institutions exchange it for public supply. its use. In early August 2019, the central bank held a video conference on work for the second half of the year. The meeting called for accelerating the pace of research and development of the national legal digital currency.
Financial asset transaction settlement
Blockchain technology naturally has financial attributes, and it is causing disruptive changes in the financial industry. In terms of payment and settlement, under the blockchain distributed ledger system, multiple market participants jointly maintain and synchronize a "general ledger" in real time. Payment, clearing, and settlement that currently take two or three days can be completed in just a few minutes. tasks, reducing the complexity and cost of cross-bank and cross-border transactions. At the same time, the underlying encryption technology of the blockchain ensures that participants cannot tamper with the ledger, ensuring that transaction records are transparent and safe. Regulators can easily track transactions on the chain and quickly locate high-risk capital flows. In terms of securities issuance transactions, traditional stock issuance has long procedures, high costs, and complex links. Blockchain technology can weaken the role of underwriting institutions and help all parties establish fast and accurate information exchange and sharing channels. Issuers handle issuance on their own through smart contracts, and regulatory authorities With unified review and verification, investors can also bypass intermediaries and conduct direct operations. In terms of digital bills and supply chain finance, blockchain technology can effectively solve the financing difficulties of small and medium-sized enterprises. It is difficult for current supply chain finance to benefit small and medium-sized enterprises in the upper reaches of the industrial chain, because they often do not have direct trade relations with core enterprises, and it is difficult for financial institutions to evaluate their credit qualifications. Based on blockchain technology, we canTo establish an alliance chain network, covering core enterprises, upstream and downstream suppliers, financial institutions, etc., the core enterprises issue accounts receivable vouchers to their suppliers, and the bills can be transferred between suppliers after being digitized on the chain. Each level Suppliers can obtain corresponding amounts of financing based on digital bill certificates.
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")solution. 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 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 superficial application based on blockchain technology. It is the first step to realize the implementation of blockchain technology, and the realization of real smart contracts is the third step.Step two. "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 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 process the data generated in each transaction link.Solidify the evidence and accurately record the time, content, and data source of data generation through time stamp technology, summary algorithm, and electronic signature technology. 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 increases the guarantee rates for most bidders to a certain extent.
At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main choice basis for the bidder. If the bidder performance records are shared through the blockchain and the performance risks of different bidders are analyzed, it will be Different bidders provide different guarantee rates, which not only reduces the risks of financial institutions, but also reduces the use costs of most bidders and promotes the use of bid guarantees. To a certain extent, it can also encourage bidders to abide by their promises and maintain the order of the bidding market. .
Promote financial services for bidding companies
The bidding behavior of bidders is scattered in various trading centers, and the data is simply aggregated In a centralized information system, there is a risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be gathered and shared safely and reliably. Through blockchain technology, bidders from multiple trading centers are gathered, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate the bidders' credit in the bidding sub-sector.
Solve the financing problems of successful bidders
Traditional corporate loans mainly evaluate the company's solvency: collateral, audit There are requirements such as accurate financial statements and sustainable profits, but most small and medium-sized enterprises cannot provide these "proofs" at all, and it is difficult to obtain financing.The scarcity of resources has become a problem 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 discountable and financing. The "tokens" on the chain can be split and transferred from first-level suppliers to second-level (and multi-level) suppliers, thereby allowing core enterprise credit to be transferred to multi-level suppliers. The shortage of funds from suppliers due to credit sales has been solved, improving the business environment; through value transfer through the blockchain, the financing cycle has been greatly shortened; the cost of supplier loans has been reduced, which will help reduce the production costs of raw materials or intermediate products, and ultimately Increase bidders' profit margins and indirectly reduce bidders' costs.
Regarding blockchain, we can imagine a decentralized management model and technical processing method.
Let me give you an example. There are five people in your family, and they have never been able to figure out how to arrange work and handle family relationships.
So, you and your family discuss it together and simply use voting to solve the problem.
Then this way of voting to solve problems can be called the most elementary blockchain.
Decentralization solves problems.
What application scenarios can blockchain have?
In fact, many of our families and many organizations use blockchain management forms every day
However, this kind of blockchain application for organizational relationships cannot produce Economic Value.
What are the economic applications of blockchain?
The first type is used for tax deposit certificates, bank transfers, etc.
Make full use of the traceability function of the blockchain so that all records can be retrieved and queried at any time
The second type is applied to enterprise operation and management
Enterprises using blockchain management can better solve the problems of enterprise development and allow enterprises to Able to develop faster and make more money.
Summary: The application scenarios of blockchain include taxation, bank transfers, etc., and can also be applied to business operations.
The characteristics of blockchain are distributed accounting and decentralization, but the ultimate goal is to make people get along more equally. Technology is meaningful only when it serves human values, and technology that meets human value needs will develop. Therefore, blockchain is in line with human pursuit of freedom and equality, so its trend to become mainstream is unstoppable.
Currently, there are many blockchain gimmicks, which are basically used to issue coins. The newly launched ono is a decentralized, free and global social platform. Due to decentralization, your chat communication information is peer-to-peer and cannot be viewed by others. In other words, your every word and deed will no longer be recorded and reviewed at any time like it is now on WeChat, QQ, and Facebook, freeing you from the trouble of surveillance.
In fact, blockchain technology can be used in any field. Information that previously required third-party confirmation can be completed online and confirmed at multiple nodes, making it difficult (almost impossible) to delete.
At present, blockchain is still in its infancy, and the technology is not mature enough, but it is also a better time to enter.
Blockchain is a decentralized technology. Blockchain can be applied to all products currently covered by the Internet.
The most popular application industry at present is the financial industry.
An application that has been implemented is product traceability. Alibaba and JD.com are already using blockchain technology to fully trace the origin of some of the products they sell. Consumers can trace the origin of the purchased products. There are also many blockchain applications in the digital advertising industry. Since 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. So on the Internet this numberIf there is such a place where there is an explosion of information and information, it will be like a magical treasure land.
If you ask what the blockchain can do, it is better to say what applications require the use of the blockchain. As mentioned earlier, blockchain is a safe place, so wherever data needs to be protected securely on the Internet, blockchain technology needs to be used. For example:
Because the use of blockchain technology can better protect the data of policyholders, in today’s Internet, data is value and wealth, so value protection and value transmission are the future development directions of the Internet. And blockchain technology can really do just that.
If there are any deficiencies, you are welcome to comment and correct me.
In a narrow sense, blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-tamperable. Fake distributed ledger.
The two parties involved in the transaction do not need to know who the other party is, nor do they need a third party for trust endorsement. They only need to trust a common algorithm to establish mutual trust and conduct direct transactions.
Its characteristics are trustlessness and decentralization. The destruction of each node's ledger has no impact on the entire blockchain. The blockchain runs point-to-point payments without a center that may cheat, and the security is greatly improved. Improved, the entire transaction network has changed from a star structure to a point-to-point P2P structure.
In the future, blockchain will be used in many fields and will have a great impact on human life. . It can be widely used in fields ranging from digital currency to securities and financial contracts, medical care, games, artificial intelligence, smart contracts, Internet of Things, e-commerce, file storage and other fields.
1. Cloud storage
This is the statistics of current cloud storage on the Internet. In terms of volume, Google has the largest volume, which is 8,000PB. So what if we share the idle data on the Internet?
Starlight Cloud builds a blockchain data computing and storage lake through Starlight Chain, with a total storage capacity of 15,000P (approximately 15.72864 billion G) in the future. This will be more than 10 times that of Alibaba Cloud's 1500PB! It is also more than four times the size of the Taizhou Storage Center, the largest storage lake in the world after expansion.
2. Medical aspects
Using blockchain technology to save personal medical records also retains personal medical historical data, which can be used when seeing a doctor or planning for your own health in the future. Historical data can be called directly. These data are highly private, and the use of blockchain technology also helps protect patient privacy.
⑹ Is traffic promotion a blockchain operation?
FlowVolume promotion and blockchain operations are two different concepts.
Traffic promotion refers to using various means to increase the exposure of the website or product and the number of visits to the shooting town, in order to achieve the purpose of attracting more potential customers. This process requires advertising, SEO optimization, social media promotion, etc.
Blockchain operation refers to related activities in the field of blockchain, including but not limited to blockchain technology research, digital currency transactions, smart contract development, blockchain security, etc. It also includes the marketing and promotion of blockchain projects, but its main purpose is to promote and disseminate blockchain technology and applications.
Although traffic promotion, travel distribution and blockchain operations may sometimes overlap, they are two different concepts and need to be judged based on specific circumstances.
⑺Is traffic promotion a blockchain?
Traffic promotion is not a blockchain. According to the query of relevant public information, traffic promotion and blockchain are two different concepts. Traffic promotion is a marketing method that uses various channels and methods to increase the number of views and visits to a website or product. Blockchain is a distributed ledger technology used to record digital currency transactions and the secure storage and transmission of other data.
