1. blockchain world is proced by Jingtong technology< Make complaints about br / > block chain
2. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.
3. It's a long story about the difference between 32-bit and 64 bit systems. First of all, let's understand the architecture technology of CPU. Usually we can see that there are x86 and x64 marks on computer hardware. In fact, these are two different CPU hardware architectures. X86 stands for 32-bit operating system and x64 stands for 64 bit operating system. So what does the "bit" in 32-bit and 64 bit mean? Compared with 32-bit technology, this bit of 64 bit technology means that the data width of cpugprs (general purpose registers) is 64 bits. The 64 bit instruction set is the instruction that runs 64 bit data, that is, the processor can run 64 bit data at a time. Let's take a simple but not particularly accurate example: the 32-bit throughput is 1m, while the 64 bit throughput is 2m< First, download a ghost version of win7 operating system, and now Doudou takes "deep technology ghost win7 SP1 x64 computer city installed version v2013.10" as a demonstration.

in today's mobile payment era, few people will use coins for payment . A lot of people, they think that mobile payment is more convenient, if you carry RMB, it will be very troublesome, so now less and less people use paper money to pay. In fact, the process of making paper money is also very complicated. The materials used to make coins are different metals. Compared with those rare metals, low-cost metals are more suitable for making coins
< / blockquote >
and those rare metals, such as gold or silver, are suitable for making commemorative coins with collection value . In many countries, some of their currencies are made of alloy, because it is a very ideal material for coinage, and the hardness is improved by mixing with other metals. At the beginning of making coins, we should choose the materials and put the selected metals in the furnace for casting and melting. After many times of rolling in the rolling workshop, the thickness of the coin can meet the requirements of coins, and it can be made into semi-finished procts for further processing{ RRRRR}
with the progress of science and technology, now many mold making machines have become engraving machines for casting to replace the previous manual process . It can improve the accuracy to a certain extent. It used to take a whole day to manufacture, but now it can complete the remanufacturing of the mold within a few hours. After that, it can be pressed on the coin, and the coin will become the currency in circulation

8. This is Ethiopian coffee. There are many kinds of coffee. Different kinds have different characteristics. Which one do you want to ask
9. Ifconfig shows the received packet loss. Generally speaking, the driver does not have enough memory to store the received packet
the received packet loss statistics is stored in the data structure net_ device_ In the following field of stats,
unsigned long RX_ dropped; /* No space in Linux buffers * /
so it's neither a hardware problem (or you can't receive packets at all), nor an ARP attack (regardless of the upper protocol type of the driver). It may be that the memory is not enough, but it's not sure. The owner can check the driver of your network card to confirm
10. Is it for maintenance? Someone in China can repair it
