Jingxiandong blockchain cross border
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.
Blockchain is a shared database. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on
main features:
1. Decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage
2. Openness. The foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface
3. Independence. Based on consensus specifications and protocols, the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
extended data
application direction:
1. Payment: for example, in terms of time, traditional cross-border remittance takes 10 minutes or several days, while blockchain cross-border remittance can achieve remittance in seconds e to decentralization. In terms of convenience, traditional cross-border remittance needs to wait until the next day after 19:00, while blockchain cross-border remittance only needs one mobile phone to realize all-weather remittance
2. Sharing medical records: the medical data blockchain sharing platform can achieve many application scenarios. Patient history data and other information can be linked, and medical history and image data can be viewed by personnel entering the system. These medical data can also be used for modeling and machine learning

Why 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
the essence of the Internet is still centralized, so whether it's a company or an indivial, we should consider the problem out of our own interests
at the user level, the concentrated thinking is how much money I have to pay and how many users I get is cost-effective. But the essence of blockchain is decentralized
the company or project party should consider how to let users, consumers, and even investors do more, and then unite more project parties and third parties to build an ecology, where resources are shared and interests are related, so it can play a greater role
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.
, the world's first electronic wallet cross border remittance service based on block chaining, was launched in Hongkong in June 25th. Hong Kong Alipay AlipayHK users can send remittances to Philippines purse Gcash through block chain technology. p>
ant financial services said that alipayhk cooperated with gcash to become the first e-wallet in the world to use blockchain in the whole link of cross-border remittance, and Standard Chartered Bank was responsible for the day-to-day capital clearing and foreign exchange. Gcash users can consume immediately after they arrive at the account. Cross border remittance can also arrive in real time like domestic transfer, 7 × 24-hour uninterrupted, cost-effective, safe and transparent, it can be said to redefine the "cross-border remittance"
the similarities between stocks and cryptocurrency are as follows:
the most similar thing between stocks and cryptocurrency is that the value of both depends on the next buyer. If the price of the stock / cryptocurrency is $10, and a seller wants to sell it for $100, he will find a buyer and buy the stock / cryptocurrency, then its value will become $100. So to some extent, the most important factor in the value of stocks / cryptocurrencies is the willingness of other buyers in the market to buy / sell
differences:
< EM > 1, ownership and voting rights < / EM >
cryptocurrency will not give you ownership and voting rights. In the field of stock, if you own 1% of the company's stock, it means that you have the right to vote at the company's general meeting, and you also have the right to obtain 1% of the company's remaining assets after the company goes bankrupt (Note: some dpos projects also have the right to vote, but these are meaningless for cryptocurrency transactions)
< EM > 2. Dividends < / EM >
stocks can receive dividends. Outstanding companies will distribute dividends to shareholders every year, and the annual dividend is a few percentage points of the stock. In cryptocurrencies, the dividend feature does not exist
< EM > 3. Insider trading < / EM >
stocks are strictly regulated by the government, and there are many regulations and laws of listed companies. For example, people in the stock market are forbidden to trade stocks based on insider information (information that affects the company's share price). But this kind of insider trading is very common in the cryptocurrency market
for example, a works in a listed company, and he happens to know that the company has developed a perfect market solution, which will be released next Monday. If a buys shares this week, he is likely to be sentenced for insider trading. But if a's company is a cryptocurrency company, he will not bear any responsibility, and can harvest all the benefits of new news release
Financial statements regulatory authorities require listed companies to publish quarterly and annual financial statements to show the company's business development and future development ring this period. However, in the cryptocurrency market, the issuing company is not obliged to disclose any information about the company's financial statements There is no doubt that when deciding which digital currency to invest in, the lack of financial statement information will make it difficult for investors to judge the potential risks of cryptocurrency The trading time is limited to 17:00 on weekdays and closed on weekends. If you buy the stock of a listed company, you can sit comfortably on the sofa when the stock closes without worrying about the fluctuation of the stock price, but this is impossible in the cryptocurrency world. Cryptocurrency trading is open for 7 * 24 hours, which means that investors in cryptocurrency have no time to relax< EM > 6, transaction costs < / EM >
cryptocurrency mainly includes withdrawal costs and transaction costs. In the field of stock, you need to bear stamp ty, commission, transfer fee, other expenses, etc
