Trust universal miner
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items[ 1-2]
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to bitcoin's status quo of encouraging illegal activities and disrupting financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency.

At the beginning of the game, there will be a torch and stone. You can choose to smash the oil bucket on the side of the road, or you can buy some materials and wastes. Meet players as far as possible not big, can go together. I suggest you play national service. There are many Chinese players in it. If you can understand what to say, the players in European service are more friendly, the players in Korean service are good at shooting, but the quality of the players in Japanese service is poor. That's all. But I downloaded the reality mole. Like a friend like it, thank you
according to the characteristics and positioning of rust, it is suitable for fields with strong control and performance sensitivity, such as underlying software (OS / driver), basic system software (compiler / VM / DB, etc.), application software with high performance requirements (Browser / graphics and image processing / game / high performance server software, etc.), or ml application direction that may be popular recently<
2.
the underlying software (such as OS / driver) has a great coincidence with the application field of C. in this field, I think it has little impact on C
C is good enough here, and these fields are highly technical, but the business logic is not too complex, and the advantage of rust is limited. Moreover, compared with C language, rust brings a certain "black box" and some unnecessary language complex features in these fields
as a "portable assembly", C is very suitable for this field, and other languages can hardly pose a challenge
3.
except for the bottom software (OS / driver and so on), C + + has the most advantages
in these areas, C + + provides more advanced features than C to facilitate development, and has higher performance and less memory than JVM Although some well-known software in these fields are C and JVM based, such as PostgreSQL / redis / nginx / Hadoop / spark, only C + + is omnipotent in these fields at present.
I think the main battlefield of rust is here, and the opponent that needs to fight is C + +
the existing power (system / code / people / habits) of C + + is so powerful that it is very difficult to completely defeat C + + in these fields. And C + + is also developing, and the pace of development in recent years is also fast up, C + + 11 / 14 / 17 and so on
however, the historical burden of C + + is very heavy. With the development of C + +, the complexity of C + + is also increasing. Moreover, some problems (such as security / exception / complex inheritance, etc.) are genetic, which can not be remedied by adding features
the most attractive crowd of rust may be C + + programmers: on the one hand, it solves many C + + pain points, on the other hand, many features of rust are actually a little complex and a little threshold. The motivation behind these features is very easy for programmers with C + + background to understand, which is also the dream of many C + + programmers
relatively speaking, programmers with other language backgrounds are far less sympathetic to rust than C + + programmers
guess that rust will:
A. nibble away a certain C + + share. Some new projects that might have chosen C + + might have chosen rust
B. nibble away a certain share of Java. Some projects choose the JVM system because the C + + development is too complex, and the project has certain performance requirements. Then rust will eat away some of these projects after it appears
C. cannibalize a certain share of golang. Dissatisfied with GC (even if 1.5 is improved, the inherent problems of GC cannot be completely solved), dissatisfied with generics, dissatisfied with part of the project performance. However, it also depends on whether the future concurrent solution of rust is ideal enough. 1.0 is out of the question
D. mobile rust is enough in terms of its own strength. But it really depends on the "father" of mobile devices
rust has some obvious advantages and is very competitive in these fields
rust community must pay attention to ide development environment, and spend energy to develop high-quality ide plug-ins of eclipse / Intel Ji / VS, which is very helpful for promotion and popularity
as long as the rust community doesn't make the trouble of repeatedly tossing D language, can do a good foundation and have excellent engineering quality as the golang community, then the future of several killer applications of rust is very promising.
