How to pay for trade on blockchain
ICO trading is roughly divided into two parts, one is OTC trading, the other is exchange trading. There are three ways to go to the exchange, the first is to vote on the currency, the second is to invest in the currency, and the third is to cooperate with the project party
for the exchange, the more platform coins consumed by voting, the better; For the project side, the lower the cost, the greater the impact of users, the better; But for ordinary social users, the easier it is, the better
What does the project party need to have
{rrrrrrr}
the cost of project docking with the exchange:
at present, the popular Matcha exchange generally has about 12-15 BTCs,
biki and gate exchange have about 10 BTCs,
ZG exchange has many choices when docking with 6-8 BTCs,
2-5 BTCs, such as Lein, ZBG, fcoin, WBF and so on
Fcoin, which is relatively cost-effective, is also a good choice. Later, the project parties can work together with the platform to do activities, whether it is airdrop, IEO or other can be discussedif 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.
blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. At present, they keep their own accounts.
with the continuous development and progress of society, great changes have taken place in our lifestyle, such as mobile payment and online shopping, which have brought great convenience to our life. Since the birth of online shopping, online payment has become a part of our life
online shopping is convenient, but it is also through the middle of a "invisible" process of payment, such as we bought something on the Internet, first pick out what you love, then you have to pay the problem:
now most people use Alipay is the way of payment, then first Alipay will receive payment request. Then it initiates the protocol to the network, saves the information to the database, and forwards the request to the bank. When the Alipay account shows that the dection is successful, it will have to be connected to the bank through the Internet. Then the buyer will confirm receipt after receiving the goods, so that the buyer will dect the money before transferring to the seller's account. Not only is the transaction process too cumbersome and complex, it is clear that the transaction between the two parties has to go through a series of links. More importantly, once the intermediate payment link collapses, the whole transaction will stop, and the subsequent operation is really troublesome
in fact, the popular explanation is that when I want to buy something, I give the money to the middleman and ask him to help the seller. If the middleman makes any mistakes, it may lead to the situation that the money can not be recovered and the goods can not be obtained
is there any way to simplify the transaction process and improve the transaction efficiency? Yes, the current hot blockchain technology and digital currency payment can better solve the above problems:
blockchain has become one of the hot topics in the past two years. Blockchain can replace the existence of these third-party services:
first, blockchain can not be tampered with. Every transaction will be distributed to each block for record keeping, Then use cryptography to verify, any malicious damage or record deletion will be found, so the whole process of shopping will be seen. Blockchain strengthens the trust, traceability and transparency in the transaction, making our transaction faster and more convenient<
the second is the unique payment characteristics of digital currency:
the decentralization of digital currency can eliminate the intervention of the third party, and there is no need to worry about the problems of the third party, resulting in the whole transaction payment process can not continue
the point-to-point transmission of digital currency saves the time link in the whole payment process and realizes fast payment, so that both parties can receive money quickly and save time
openness and transparency of digital currency: except for cash transactions, all transactions based on online payment are just a series of numbers, and all transactions of digital currency are open and transparent. You can check the transaction records of all payments, which can ensure the security of the overall commodity payment
and like China's booming WeChat, Alipay and other payment platforms, cross-border payment has been realized, but there is a problem that fees will be more expensive than domestic payments, and the settlement cycle will be longer than domestic. In general, efficiency will be slow, time is long, and hand renewal is expensive. Digital money will make traditional transactions "no longer traditional". That will also make cross-border payment more efficient: digital currency is not subject to the "constraints" of any country or bank. Based on blockchain technology, it can just bypass this centralized system with low handling charges, and its point-to-point transmission transaction characteristics can effectively improve the current problems of long-time and high cost of cross-border payment
the times have been developing, and the way of life is constantly improving. Online shopping and payment are born from our development, with both advantages and disadvantages. Then we will try our best to push everything in a better direction
digital currency is on the rise. Although the current digital currency is not perfect, many countries have begun to use digital currency as a payment method. Due to the various characteristics of digital currency, bitcoin, Ethernet, Las Y2, QTP (wechat ID: yingbivc), ASEC and other digital currencies are being actively used. They can not only simplify the traditional online payment transaction process, but also circulate payment around the world and rece exchange rate issues such as handling charges. Don't just look at digital currency with one eye. Maybe in the near future, it will open the era of digital currency full payment!
In the traditional supply chain finance, financing difficulty, high financing cost and cumbersome financing process have always been one of the bottlenecks restricting small and medium-sized enterprises to become bigger and stronger. Banks rely on the ability of core enterprises to control goods and regulate sales. For the sake of risk control, banks are only willing to provide factoring services to upstream suppliers (limited to first tier suppliers) with direct accounts payable obligations of core enterprises, or provide prepayment or inventory financing to their downstream distributors (first tier suppliers). As a result, the demand of secondary and tertiary suppliers / distributors with huge financing demand can not be met, the business volume of supply chain finance is limited, and the small and medium-sized enterprises can not get timely financing, which will easily lead to proct quality problems and damage the whole supply chain system
to solve these problems, we can make use of the characteristics of decentralized, tamper proof and distributed ledger of blockchain technology to build a blockchain supply chain financial platform
The core enterprise issues a / R certificate to the distributor. After the distributor signs the receipt, it indicates that it has signed the purchase and sales contract and the core enterprise delivers the goods Because of the shortage of funds, distributors need to borrow money from finance3. After the financial institutions have approved, the amount of loans will be sent to the core enterprises
The distributor will repay the loan and interest after selling the goodsWhy is the Internet era coming to an end and the blockchain era coming
Once the 
blockchain develops, it will burst out more innovation. As the first proct of blockchain, bitcoin has proced many innovations since its birth. For example, small cross-border payment, recording transfer transactions between currencies, recording various stocks, registering housing property rights, recording program codes, etc.
the steam age liberates social proctivity, the electrical age enlivens social cooperation ability, the Internet age connects the world, and the blockchain era will let us truly realize freedom
In recent years, it has become a well-known fact that the wave of science and technology has changed the financial instry. Focusing on the application and research of big data, cloud computing, blockchain, artificial intelligence and other technologies in the financial field has become a hot spot, further giving birth to the new concept of financial technology. Financial technology covers a wider range of fields than Internet finance. Based on Internet technology, it uses more cutting-edge information technologies such as big data, cloud computing, Internet of things, blockchain and artificial intelligence to improve financial efficiency and create new value. Its main business fields include payment and settlement, fund raising, asset management and technical services
since 2017, the trend of financial technology has become more prominent. On the one hand, the people's Bank of China has formally established the financial technology committee, which defines the status of financial technology and its important role in driving financial innovation and better serving the real economy; On the other hand, the five major banks of instry, agriculture, China Construction, and communications have reached cooperation with the five Internet companies of Internet, Alibaba, Tencent, Jingdong, and Suning respectively, which shows that the banking instry attaches great importance to the field of financial technology and follows up quickly
according to relevant experts, new technologies such as big data, artificial intelligence and blockchain are becoming more and more mature and are being applied in the field of financial services to try to solve the security and trust problems between finance and real economy. This means that driven by financial technology, finance and the real economy are developing together, and a new era of service capacity and level is coming
1. Financial technology forces the transformation of banks' thinking mode: as the basic business of commercial banks, trade finance undertakes the comprehensive service connotation of payment, settlement, deposit, loan, financing and credit guarantee, and highlights its importance in bank operation with the advantages of strong debt pull, high income output and low resource consumption. Through financial technology, in addition to recing repetitive work, improving the accuracy of verification and the convenience of interaction, we can also mine previously imperceptible information, relationships and trends through the comprehensive analysis and application of structured and unstructured data, and mine new business opportunities on the basis of improving the ability of data acquisition, analysis and Application, so as to improve the ability of risk prevention and control. Therefore, trade finance business also needs to conform to the trend, change the mode, and use financial technology to improve the ability of trade finance services
With the development of network technology, banks have accumulated a certain amount of technology in the field of trade finance. For example, in the process of bank opening L / C, the application data can be directly extracted and transformed into L / C by using the relatively mature digital technologies such as OCR (optical character recognition) and ICR (intelligent character recognition), replacing the tedious manual input. In March 2017, the cross-border e-commerce payment system of China Everbright Bank was officially launched. The system is designed according to the characteristics of the one-stop demand of cross-border e-commerce, integrating the settlement and sale of foreign exchange, collection and payment. The third-party payment institutions can successfully complete the diversified operations of online settlement and sale of foreign exchange, collection and payment of foreign exchange, and provide the whole process of cross-border payment financial services for cross-border e-commerce payment transactions. The launch of the cross-border e-commerce payment system of Everbright Bank has opened up the domestic and foreign capital flow channels of the third-party payment institutions, and improved the bank's cross-border financial service system2. The banking instry actively tested the "blockchain + trade finance business": (1) domestic letter of credit . In July 2017, Minsheng Bank and China CITIC Bank pioneered the blockchain based domestic letter of credit information transmission system (BCLC) (phase I). This is the first time that the domestic banking instry has applied blockchain technology to the field of L / C settlement. It can not only shorten the sending time of the original paper-based letter of credit, but also make all aspects of the letter of credit more transparent and traceable, and avoid errors and fraud. In September 2017, Suning Bank successfully connected to BCLC. In April 2018, Ningbo Branch of Minsheng Bank successfully handled the first blockchain domestic letter of credit business through BCLC. The successful trial of the first blockchain domestic letter of credit not only effectively improved the efficiency of L / C issuance, improved the customer experience, but also broadened the trade and financial channels 2 Forfaiting transaction , in November 2017, China Construction Bank completed the first blockchain Forfaiting transaction (including the financing form of buying bills or buying out bills), with an amount of nearly 100 million yuan. This is another major breakthrough innovation of CCB in the field of "blockchain + trade finance" after the application of blockchain technology in the field of domestic letter of credit. In September 2017, Hangzhou United Bank joined the "China trade finance blockchain alliance" initiated by China Construction Bank to actively support the development of blockchain trade finance. In January 2018, Hangzhou United Bank and Zhejiang branch of China Construction Bank completed the first inter-bank blockchain Forfaiting transaction in China. With the help of trade finance blockchain, it connects the buying bank and the selling Bank of Forfaiting. Through online matching of transaction inquiry and quotation, online operation of process and other functions, it realizes the electronization of transaction documents and visualization of transaction process, effectively improves the timeliness, security and convenience, and shows the integration role of blockchain in financial technology, It also breaks through the cross system limitation of blockchain technology 3 International Factoring , in January 2018, China Construction Bank launched its first international factoring blockchain transaction, becoming the first bank in China to apply blockchain technology to international factoring business, and for the first time realizing the "fablock eco" with the direct participation of customers, factoring commercial banks and other parties in the instry. In the field of factoring, it creatively integrates both sides of the basic trade into the blockchain, and realizes the automatic identification and assignment of qualified accounts receivable through intelligent contract technology. The whole transaction is visualized and traceable, which effectively solves the operational problems of complicated message transmission and complicated right confirmation process in the development of factoring business, It is of great and positive significance to prevent the fraud risk in traditional trade financing and improve customer experience
3. Improving the ability of data becomes the core competitiveness of developing trade finance: Science and technology is not omnipotent, because of the inherent complexity of financial risk, financial risk will not disappear because of the development of technology. And with the rapid entry of Internet giants, financial technology companies, instry leaders and other non banking institutions, it will create a new competitive pattern. In addition, it is difficult to predict the risk generation mode, the change of transmission path and the acceleration of transmission speed that the new technology may bring. In such a competitive situation, banks must make full use of their own information base, and with the help of the favorable conditions of digital financial management carried out by a large number of enterprise customers, as well as the integration of procurement, proction, sales and financial data management, to comprehensively promote the digitization of trade financial services. With the help of financial technology to establish high-quality database, strengthen the basic ability of stable and fine data analysis, and provide long process and multi scene applications in trade finance services, providing data support for accurate prediction, accurate marketing, accurate innovation and accurate pricing
