1. This is not a rigid rule. It has nothing to do with blockchain. There is a relationship between the algorithm of this currency. The confirmation method of each currency is different, so this is not a rigid rule
the confirmation times of bitcoin are different from that of Ruitai coin, Laite coin and doggy coin.
the confirmation times of bitcoin are different from that of Ruitai coin, Laite coin and doggy coin.
2. Similar to the stock exchange, blockchain exchange is the website platform for digital currency trading. Xrv522 can develop blockchain exchanges. These trading platforms generally only provide functions such as recharge, transfer and cash withdrawal. In other words, they will only tell you the collection address of your wallet, while the key, keysore and mnemonic words of your wallet will not be provided. Identity authentication is completed through login user name, password, verification email, mobile phone and other ways
(1) introction to price limit trading mode:
price limit buying / selling refers to that the user sets the price and quantity of a buying / selling currency to generate an order. The system will automatically match the buying and selling orders in the market. Once the price set by the user is reached, the transaction will be automatically executed according to the price priority time priority
(2) introction to market price transaction mode:
market price purchase refers to that the user sets a total amount and generates a commission order, from the beginning of selling to the completion of the total amount transaction. Selling at market price means that the user sets the total number of currencies to be sold, generates a commission document, and matches it from the beginning of buying to the completion of the total number of currencies transaction
(3) introction to currency transaction mode:
currency transaction is mainly aimed at the transaction between virtual digital assets and virtual digital assets, in which one currency is used as the pricing unit to purchase other currencies, and the currency transaction rule is also to complete matching transaction according to price priority and time priority< (4) introction of C2C transaction mode:
both parties of the transaction release the transaction information of buying or selling currency on the C2C transaction platform according to the demand. The buyer and the seller complete the transaction offline according to the agreed payment method, and the platform, as an intermediary, charges a certain proportion of the handling fee from each successful transaction< (5) introction to OTC OTC trading mode:
it is a set of platform for offline purchase of digital currency independent of the exchange. Businesses can publish purchase / sale advertisements on the platform, and purchase / sale users can purchase / sell through offline transfer. After the transfer, the platform will transfer the frozen digital currency to the buyer, The technical construction problems of the exchange can be found on the Internet
(6) introction to trading mining mode:
the exchange platform returns a certain proportion of the commission income to the platform users, and the platform coin is returned. According to the principle of distribution proportion, the exchange platform takes a certain proportion as the mining reward. Mining refers to trading on the platform to graally unlock the platform coin until all the platform coins are fed back. This kind of play has a strong attraction to attract users< (7) introction to futures / contract trading mode:
futures contract is an agreement that the buyer agrees to receive certain assets at a specific price after a specified period of time, and the Seller agrees to deliver certain assets at a specific price after a specified period of time. The price that both parties agree to use in future trading is called futures price. The designated r period in which both parties have to trade in the future is called the settlement date or delivery date. The assets agreed to be exchanged by both parties are called "subject matter"< (8) introction to the trading mode of perpetual contract:
perpetual contract is a new and unique contract. The goal of the contract is to allow high leverage to the market conditions of the spot market. The contract will not be delivered and can follow the reference price index through various mechanisms. The contract evolved from the traditional futures contract, but the perpetual contract has more obvious advantages and greater risks than the traditional futures contract, supporting long short two-way trading, opening a 100 times leverage, permanent position, premium and so on.

first, define the
blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain
Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network securityin the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent
In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees4. The transaction fee will be dected from your total transaction amount. If BTC assets are acquired after the transaction, BTC transaction fee will be paid; On the contrary, if the digital assets are acquired after the transaction, the transaction fee of digital assets will be paid
if you sell 10eth with 1btc, 0.2% eth Commission will be dected, and 9.98eth will be obtained from the sale
if you buy 1btc with 10eth, you will get 0.998btc by decting 0.2% BTC handling charge.
if you sell 10eth with 1btc, 0.2% eth Commission will be dected, and 9.98eth will be obtained from the sale

Let's suppose villagers Lao Wang and Xiao Li. Lao Wang borrowed some money from Xiao Li, who wrote it in an IOU signed by both parties. A few days later, Lao Wang denied the existence of borrowing money and claimed that Xiao Li forged the paper. Xiao Li can't argue because he finds it difficult to prove that Lao Wang actually owes him money
in this example, Lao Wang and Xiao Li are two nodes
now assuming the same scenario, there are many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be difficult to do so. Seeing this scene, the village head came up with a solution. He suggested using a common notebook for the whole village to record all the transactions. Due to the high prestige of the village head, the villagers unanimously decided to let the village head keep this important transaction book. Each transaction, the villagers go to the village head's home, let the village head witness and record, each transaction is written into a notebook, and then safely saved. That notebook can be called a database
because this notebook is very important, the village head locked it in the safe. However, there are always some problems. Sometimes, the village head will accidentally sprinkle ink on the paper, making some transaction records illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village head's house. He tries his best to steal it. This is called hacking
until one day, the village head's son owed others a lot of money, so the village head secretly deleted his son's debt entry. In this way, the village head's son "does not owe money."
when the villagers knew this, they began to question the fairness and authority of the village head. So some people put forward a new idea:
abolish the power of the village head, which is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and distributed, which is called distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time there is a trade between any two people, all the people in the village get together and record it in their notebooks. And no one can cover the sky. This is called decentralization
they also decided that they would never delete the mentioned transactions from their notebooks, which is irreversible. For example, Lao Wang borrowed a sum of money from Xiao Li before, but in the twinkling of an eye, he wants to return the money. Then the transaction book will not delete the previous borrowing record, but write a new repayment record, so there are two records
next, let's try to break this rule. What if we bribe Lao Wang to change his notebook? It's not feasible, because the next time the villagers meet, they find that Lao Wang's notebook is different from everyone else's, so the villagers notice that Lao Wang may be engaged in an indescribable transaction, and decide to abolish Lao Wang's transaction record and kick Lao Wang out of the organization
What if you try to bribe all the villagers? It's too expensive
the characteristic of this model is that greedy people need to pay a lot to attack the rules. He will find it more profitable to follow the rules
a smart child in the village suggested that each transaction data be called "block" and linked into a "chain" in chronological order, which is called blockchain
6. The solutions are as follows:
1. Regularly clean the st in the computer, turn off the computer, open the chassis, use a hair dryer and blow with cold air< At ordinary times, 360 guard, Jinshan guard and other tools should be used to clean up the system garbage and temporary files generated by the Internet, and check and kill malicious
Italian software
3. The computer configuration is poor, so try to set the virtual memory as large as possible, and install anti-virus software with less resources, such as NOD32, or only one
auxiliary anti-virus software
4. Try to set the IP to static IP, which can rece the startup time of the computer
5. Don't put too many files and icons on the computer desktop, which will slow down the reaction of the computer. Try not to install the software on disk C
6. Regularly defragment the disk. Open the drive of my computer to defragment - properties - tools
select the disk to be defragmented. Open the "disk defragmenter" window - Analysis - defragmentation - the system will start to defragment

7. Since the implementation of the People's Republic of China Bidding Law 2011, for the first time, "electronic bidding has been encouraged by the state to encourage information networks", electronic bidding has graally emerged in the Internet plus procurement. With the green light of policy in recent years, electronic bidding technology has covered engineering construction, major equipment bidding procurement, government procurement, drug procurement and other fields< Since br />2013, the state has been promoting electronic tendering and bidding in the layout, and has promulgated important rules and regulations such as the electronic bidding and bidding system and the "Internet plus" bidding and procurement action plan (2017-2019 years). Hebei province seriously implements the national deployment and requirements, takes the implementation of electronic bidding as a key task of comprehensively deepening the reform, and is listed in the provincial key reform project in 2017. Hengshui, as the only pilot city, takes the lead in carrying out the whole process of electronic bidding in Hebei Province< On April 9, 2019, the Department of housing and urban rural development of Guangxi Province, the national development and Reform Commission and the Administration Bureau of organ affairs jointly issued the notice on continuing to promote the electronic bidding of housing construction and municipal infrastructure projects (Draft for comments)
on May 19, 2019, the general office of the State Council transmitted the guidance on deepening the integration and sharing of public resources trading platform issued by the national development and Reform Commission, One of its main goals is to "fully implement the electronization of public resources and realize the online real-time supervision of the whole process of public resources transactions" by 2020....
on May 30, 2019, the decision of the Standing Committee of Hebei Provincial People's Congress on strengthening the supervision and management of the construction market was deliberated and adopted by the 10th meeting of the Standing Committee of the 13th Hebei Provincial People's Congress and implemented on June 1, On June 15, 2019, the general office of Guangzhou Municipal People's government officially printed and issued the implementation plan for deepening the reform of the bidding system of construction projects in Guangzhou (hereinafter referred to as the plan), and proposed nine reform measures in view of the new situation and new problems in the current bidding work, To further deepen the reform of the bidding and tendering in Guangzhou construction project, China's tendering and bidding public service platform in from July 18th to 19th
2019 held a two day collaborative promotion of Internet plus bidding technology innovation achievements in Beijing. The conference mainly focused on the three themes of "CA code scanning mutual recognition and sharing", "system network, big data, security" and "blockchain", CFCA mobile electronic authentication: to build the whole process security guarantee of handheld electronic bidding....
on July 24, 2019, the first anniversary of the whole process electronic bidding in Hengshui, Hebei Province....
the above electronic bidding pilot and policy promotion have made the electronic bidding develop rapidly in the whole country, and become an important platform for engineering construction, government procurement, information technology and so on Mineral trading and other fields of the mainstream bidding mode. Electronic bidding is closely related to the development of information technology all over the world. With the rise and development of e-government, commerce and project management, electronic bidding has become the main means of bidding, which is an inevitable development trend
looking forward to the future, how will electronic bidding develop
Future Prospects: the government, large state-owned enterprises and third-party institutions will work together to build a benign ecological environment for electronic bidding
(1) as the main three parties involved in the E-bidding market, the government, large state-owned enterprises and the third-party E-bidding institutions can only build a benign ecological environment of the instry and build an efficient, open, fair and just bidding instry pattern through win-win cooperation
(2) as the main body of the public resources trading center, the government must perform the supervision and management responsibilities, accelerate the reform of the separation of the three networks, separate the administrative supervision platform, public service platform and electronic bidding trading platform, distribute different functions to the most professional people, and guide the market capital to actively participate in, which can effectively prevent insider trading, Improve the overall efficiency and transparency of the instry
electronic bidding is a bidding activity completed in the form of data message. Generally speaking, it means that some or all of the paper documents are discarded, and the business processes such as bidding, bidding, bid evaluation, contract signing, and even the whole process are electronically realized by means of computer and communication technology
there is a special definition of bidding in China, and bidding activities are subject to the bidding law and its implementation regulations. For electronic bidding, the national development and Reform Commission, the Ministry of instry and information technology, the Ministry of supervision, the Ministry of housing and urban rural development, the Ministry of transportation, the Ministry of railways, the Ministry of water resources and the Ministry of Commerce jointly formulated the "electronic bidding method" and its annex "technical specification for bidding system" The promulgation of the measures for electronic tendering and bidding will provide unified standards and legal basis for the practice of electronic tendering and bidding in various regions and departments, and make it develop in a more standardized and unified direction
it should be pointed out that the online bidding operation of each trading platform will be slightly different. In actual operation, we also need to understand the specific process of a specific trading platform. Do specific analysis of specific problems
on the issue of E-bidding, what are the advantages of E-bidding
e to the existence of E-bidding, the traditional bidding methods are suffering from the test of the times, and the future prospects become uncertain and unpredictable. With the strong support of national policies for E-bidding, E-bidding has been widely used in engineering bidding, e-procurement, government procurement and other instries. Following the pace of China Bidding network to analyze the advantages of electronic bidding
combined with the views of experts and instry insiders, several advantages are summarized:
1. The bidding instry is full of corruption, and transparency is more important. All information of bidding projects, including procurement, bidding notice, bid winning announcement, etc., are publicly released on the electronic bidding system to realize the open, fair and just principles of bidding activities
2. Rece the cost and improve the efficiency
using the electronic bidding system, the cost is lower. Save manpower and material costs
3. Detailed analysis of bidding documents and locking of illegal clues
the system automatically records the user's hardware characteristic code, tool software, pricing software identity code, etc., binds the information with the bidding documents, and concts identification, comparison and detailed analysis of these information that should not be the same ring bid evaluation, which can effectively lock the illegal clues< In the traditional bidding activities, the bidding data can only be managed by manual registration or re entry, which not only wastes manpower e to repeated labor, but also provides effective data support for government regulatory departments to grasp the instry development status and trend in real time and make scientific macroeconomic decisions, Moreover, because the data update is not synchronized, the data association is poor, resulting in the disconnection between business and management. The electronic bidding platform directly collects relevant information and data in the business process, which is closely related and has strong linkage effect. The preciseness of the bidding process ensures the accuracy and reliability of the data information. Through the accumulation of a certain period of time, the formation of the bidding resource information database is concive to the analysis and summary of the bidding and procurement work of the bidding agencies, and improve the level of business management. At the same time, it provides effective data support for the government regulatory departments to grasp the current situation and trend of the instry development in real time and make scientific macroeconomic decisions
5. Keep the bidding information confidential, increase the difficulty of breaking the rules, and detect and curb the bidding collusion
through the application of online downloading bidding announcement, online bidding registration, online downloading bidding documents, online answering questions, online payment and other functions, the handling situation of each node can be quickly fed back through the SMS platform. In this way, the information of bidders is in a highly confidential state before the deadline of bidding, which makes it difficult for those who intend to collude with each other to master the relevant information
6. Set up multiple rounds of inspection to curb the directional rejection of bids
conct comprehensive proofreading and inspection on the integrity, conformity and accuracy of the contents of the bid documents in multiple links such as bid preparation, upload and evaluation, so as to prevent the judges from choosing the directional rejection of bids with the intention of bid evaluation, so as to cut off the interest relationship between the judges and some bidders< (1) the online bidding system is supported by the enterprise credit database. Once confirmed, the fraulent enterprises will be listed in the blacklist database and publicized online. The system will automatically close their information channels, and they will not be eligible for online registration in future bidding activities. This undoubtedly increases the illegal cost of bidding enterprises, Make bidding enterprises cherish bidding credit record more
(2) through the information feedback from the bidding units to the construction units, the malicious default of the construction funds of the construction units can be effectively curbed, which helps to improve the integrity construction of the construction units; Improving the evaluation system of judges is concive to supervising the professional ability and professional ethics of judges
the Internet has profoundly changed people's way of work and life, and has become a new form of business. Electronic bidding is the core application of "Internet plus bidding", and will graally become the mainstream mode of China's bidding field.
