Realizing blockchain currency
for your question, the development of multi currency trading system based on blockchain needs to develop a system with stability and security. For the specific system development scheme, please refer to the system development of Yingtang Zhongchuang, whose blockchain technology is reliable.
compared with other ways, using bitcoin to remit money is much more "secret". Normal cross-border remittance will go through the examination of exchange control institutions at all levels, and the transaction records will be recorded by banks and other parties. Transactions exceeding a certain amount should be reported to relevant departments to prevent money laundering and other violations. Bitcoin, with the characteristics of globalization, is usually used as a tool for cross-border payment and remittance. As a kind of network encryption virtual currency, bitcoin has the characteristics of decentralization and anonymity,
capital flow is not easy to track, and it is easier to hide identity
wannacry blackmail virus prevention method:
1. Install the latest security patch for the computer. Microsoft has released patch ms17-010 to fix the system vulnerability of "eternal blue" attack. Please install this security patch as soon as possible; For Windows XP, 2003 and other machines that Microsoft no longer provides security updates, we can use 360 "NSA Arsenal immunity tool" to detect whether there are vulnerabilities in the system, and close the ports affected by the vulnerabilities, so as to avoid being infringed by blackmail software and other viruses
2. Close ports 445, 135, 137, 138 and 139, and close network sharing
3. Strengthen the awareness of network security: don't click the unknown link, don't download the unknown file, don't open the unknown email...
4. Back up the important files in your computer to the mobile hard disk and U disk as soon as possible (regularly in the future), and save the disk offline after the backup
5. It is recommended that users who are still using Windows XP and windows 2003 should upgrade to Windows 7 / windows 10 or windows 2008 / 2012 / 2016 as soon as possible.
let me analyze it:
1: bitcoin has been broken in China, and its price has dropped sharply, which is unexpected by the global mining pool
2: compared with the current mining cost of bitcoin, it makes money entirely by cheap electricity bills
3: there are only 21 million bitcoins, and most of them have been g up in the early stage, which makes it difficult to dig those bitcoins that have not been g up in the future, and there is too much competition. Many small mines are in a state of loss
and why do many well-known mines turn to TCD
first of all, bitcoin is the optimized and upgraded version of bitcoin, with a constant number of 100 million. The early mining is very good. Unlike bitcoin, which has too high cost and low cost performance ratio, it is appropriate to use bitcoin as a supplement to compare bitcoin. Bitcoin is used for large amount payment and bitcoin is used for small amount payment.
In 1991, the Journal of cryptography published an article by S. Harper and w. stonetta, which discussed the method of adding time stamps to digital documents. In 1992, the same group of people discussed how to increase efficiency. This is the origin of blockchain technology. In 2008, the "blockchain" created by people or groups under the pseudonym of Nakamoto Tsung by bitcoin has a more idealistic color exclusive to the Internet
as one of many solutions of distributed computing, the most significant feature of blockchain compared with other distributed computing is that there is no need for administrators. For this reason, blockchain has paid a huge price in efficiency
Secondly, since digital currency is likely to become an important form of payment for sovereign currency in the future and contribute to the global use of sovereign currency, digital currency and gold are complementary and symbiotic. Blockchain provides a window to observe the real exchange rate and interest rate of sovereign currency. If we need to make the world generally accept the digital currency of sovereign countries, we need to first generally accept the credit currency of sovereign countries. As an ancient and widely accepted credit collateral, gold is obviously an important part of sovereign state reserves. With the impact of digital currency on traditional settlement system, the importance of local currency value will riseespecially with the explosive growth of global negative interest rate bonds, the number of credit collateral that can stably support the value of local currency is decreasing. At present, whether negative interest rate can last is a controversial topic in the academic circle. We tend to think that negative interest rate itself is a short-term phenomenon, and in the long run, it must be settled once and for all. In the process, as a traditional safe haven asset, gold is bound to have more space, and the trinity of gold (credit support), sovereign currency (credit medium) and digital currency (circulation means) will also be the international strategy of sovereign currency
the ideal of blockchain has failed, but the application of blockchain has just begun. The gold instry and gold should play an active role in this wave and contribute to RMB internationalization and instrial upgrading
