"Gold and silver are not money naturally, but money is gold and silver naturally." this is a sentence Marx said about money
How to understand? In fact, it is very simple that money is the inevitable proct of the development of human life. In the earliest stage, gold and silver were only used as a kind of metal or a kind of ordinary commodity to exchange things. However, with the development of society, people find that gold and silver are easy to separate, easy to preserve, easy to carry and other advantages, so the suitability of gold and silver as currency is reflected, and naturally evolved into currencyWhat about bitcoin
2. Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to the algorithm to "mine" bitcoin. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. By 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

3. Go is an open source programming language, which makes it easy to construct simple, reliable and efficient software. If you want to learn this programming language, you should first find a good tutorial. Brother Lian's go language + blockchain training has recently published a new set of go language tutorial, and the teacher's speaking is very good
with the global hot discussion of the concept of "blockchain", the application of blockchain technology has been quietly added to the daily life scenes such as finance, logistics, credit reference, manufacturing and retail. Some experts have shown that the future blockchain will be closely related to people's lives, and the integration of blockchain technology and people's daily life is the general trend
the popularity of the blockchain market has triggered a large number of talents demand based on blockchain technical personnel, and the popularity of blockchain talents is rising at the speed of light. According to the "2018 blockchain high salary list" released by lagou.com, Tencent, Xiaomi, Suning, Jingdong and other domestic enterprise giants have released many high salary blockchain post demands, trying to explore blockchain related technologies and applications. It is also pointed out in the list that the demand for high salary jobs is mainly based on blockchain related technical jobs, among which Suning and Keda have been given the highest monthly salary of 100k
the huge market demand for technical talents will inevitably lead to the explosive emergence and growth of the whole blockchain training market. Most of the training modes can be divided into online training, traditional IT organization training, and offline short-term training camps, which mainly focus on high-end forms. However, in the process of the hot market evolution, there are also a variety of blockchain training chaos: lecturers' qualifications are watered down, and even the most basic names are not disclosed, the syllabus is opaque, and the teaching quality is shrinking, Unreasonable class arrangement and uneven training fees and so on
with the large-scale development of the whole blockchain training market, brother company ecation, together with Yin Cheng, a senior blockchain expert, and his Tsinghua Shuimu Weiming team, has set up a blockchain college.

4. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm for building trust and acquiring rights and interests between different nodes in the blockchain system.
blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method for programming and operating data by using intelligent contract composed of automated script code

5. Go language is the mainstream language of blockchain
according to the data survey of boss Research Institute, go and C + + are the mainstream languages of blockchain Posts currently recruited. The early blockchain system and application
programs are mainly implemented in C + +, and now most companies will use go language to
build public chain systems<
C + + is suitable for the development of local programs.
go language is suitable for the development of network programs and local programs.
compared with C + + go, it has the following advantages:
garbage collection
clear meaning
unified format
disadvantages:
efficiency is not as high as C + + at present, but for desktop programs, efficiency is not a big problem, Because hardware is fast growing.
C + + is the mainstream language at present, and I believe it will become a classic just like C.
to become a classic means that people who learn it can get a good salary, but it is only good for themselves.
in the future network world, go will have a big chance to get hot, I think it has a bright future.
the developers of go, including the founders of UNIX and C language, are the first generation of hackers, and I believe they will do a good job.
now the go stack + blockchain market is out of an unprecedented gale, and the situation is gratifying.

6. The brainless people do brainless things. Now they change their name to Ping'an Tongzheng. It's the same group of people who continue to cheat money. Be careful.
7. This is very simple,
you can compare CPUs to doctoral students,
they are very powerful in dealing with complex problems,
and the stream processors of graphics cards are high school students.
but the number of cores of a CPU is only a few (such as 8 cores),
and the stream processors of a graphics card are often thousands.
and mining is actually equivalent to pasting envelopes,
think about it,
is it 8 doctoral students who are quick to paste the land,
or more than 1000 high school students who are fast to paste the land
mining is to use the parallel computing function of graphics card to solve simple but huge mathematical problems

8. Bitcoin transactions will be recorded in the bitcoin blockchain and cannot be modified. Anyone can query. The transaction confirmation of bitcoin is determined by bitcoin mining
mining is a distributed consensus system that includes the transaction data to be confirmed into the block chain to complete the confirmation of these transactions. By mining, the data in the block chain can be stored in chronological order, the neutrality of bitcoin network can be maintained, and different computers on the bitcoin network are allowed to agree on the system state. To be confirmed, a transaction must be packaged into a block that complies with very strict cryptographic rules and verified through bitcoin network. These rules can prevent the modification of existing blocks, because once there is a change, all blocks will be invalid. Mining is as difficult as winning the lottery. No one can easily and continuously add new blocks to the block chain. Therefore, no one can control what content is included in the block chain or replace part of the content in the block chain to rece their cost.
