1. " Generally, there is only one approximate time cycle for the development of blockchain application app. For example, starting technology mainly depends on its functions and complexity. Generally, the development time is about 2-3 months. The specific time is estimated according to the customer's needs, mainly the development time. If the functions are multiple and more complex, there will be more things to develop and design, and the time will be longer. For example, in another case, the existing source code can meet the requirements, and only need to add or modify some functions will be very fast< br />"
2. The time limit for developing a blockchain application app, such as starting technology, is estimated according to the functionality of the app. Generally, the development time is about 2-3 months, and the specific time is estimated according to the needs of customers, mainly the development time. If the functions are multiple and more complex, there will be more things to develop and design, and the time will be longer. For example, in another case, the existing source code can meet the requirements, and only need to add or modify some functions will be very fast.
3. Depending on your basic level, if you have a certain technical foundation for development, it is relatively easy to learn
"chainman College" offers short weekend technical training courses for colleges with a certain programming foundation. You can investigate them and ask about your situation.

4. Contract transaction refers to an agreement between the buyer and the seller to accept a certain amount of certain assets at a specified price at a certain time in the future. The trading object of contract trading is the standardized contract formulated by the exchange. The exchange specifies the standardized information such as the commodity type, trading time and quantity. The contract represents the rights and obligations of both parties
to put it simply, we should make an appointment to trade a certain amount of certain goods at a certain time and place in the future.

the MLM currency of blockchain will collapse on the day when the capital chain breaks as the underlying technology of bitcoin, "blockchain" is like a distributed database ledger. With the price of virtual currency based on blockchain technology such as "bitcoin" soaring, ordinary investors are increasingly interested in blockchain and digital currency
Li Xuyang, head of Tencent's security and anti fraud laboratory, said that there are more than 3000 MLM platforms using the blockchain concept. The reporter's inventory of recent cases found that "blockchain + fraud" mainly has three "routines"
extended data
with the sharp rise and fall of bitcoin and the explosion of the concept of "blockchain", many pyramid schemes under the banner of "blockchain" also appear frequently
putting on the "new vest" of blockchain, the "old routine" immediately incarnates another "new shortcut" of "Chinese aunts" in pursuit of "financial freedom" and "big pits" worth hundreds of millions. Experts suggest that relevant departments establish a joint supervision and joint strike mechanism, improve the ability of risk investigation, and timely cool down the excessive speculation chaos of "blockchain"
6. The following calculation methods can be used:
for example: microcomputer Z_ If the clock frequency of 80cpu is f = 2.5MHz, its clock cycle T = 1 / F = 1 / 2.5MHz = 400 nanoseconds (t is the basic beat of computer operation), and its shortest instruction execution time is 4T = 4 × If 400 ns = 1.6 ns, the operation speed is:
V = 1 / 4T = 1 / 1.6 × 10-6 seconds = 0.625 × 106 times / S = 625000 times / s
another example: Z_ If the clock frequency of 80A is f = 4MHz, the clock cycle T = 1 / F = 1 / 4 × 106hz = 0.25 microseconds
the shortest instruction execution time is 4T = 4 × 25 μ s = 1 μ s
then the operation speed is: v = 1 / 1 microsecond = 1 million times / second
computing speed is an important index of computer performance
commonly referred to as computer operation speed (average operation speed), the abbreviation of average execution speed of single word fixed-point instructions MIPS (million instructions per second), the number of million machine language instructions processed per second
this is a measure of CPU speed
for example, an Intel 80386 computer can process 3 to 5 million machine language instructions per second, that is to say, 80386 is a CPU with 3 to 5 MIPs
MIPS is only a measure of CPU performance
refers to the number of instructions that can be executed per second, which is generally described as "million instructions per second"
microcomputer generally uses dominant frequency to describe the operation speed. The higher the dominant frequency is, the faster the operation speed is
the CPU frequency of a computer, which generally means the main frequency of the CPU, is regarded as the engine of a car
computing speed is equivalent to the performance of this computer, which is regarded as an indicator of how fast a car can run
how fast a car can run has something to do with the road, tires, frame, etc
computing speed is the result of a multi unit cooperation, which is related to cache, data width, instruction structure, etc.
computer running speed, architecture and dominant frequency. The better the architecture optimization, the higher the dominant frequency, the better the performance
the main frequency is limited by architecture, technology and materials
the relationship between them is quite complicated. For example, the dominant frequency of Ben 4 easily exceeds 3GHz and fails to impact 4GHz. However, the highest frequency of Ben 4 is also a slag in front of the next generation of core, which is less than 2GHz. The actual running speed is far from satisfactory
therefore, the main frequency of CPU is not directly related to the speed, but it is basically positively related, that is, the larger the main frequency is, the faster the operation speed is, because the main frequency is the number of beats per second of the clock, just like the heart. The CPU will work only when it is at a high level, so to some extent, the larger the main frequency is, the faster the operation speed is.
for example: microcomputer Z_ If the clock frequency of 80cpu is f = 2.5MHz, its clock cycle T = 1 / F = 1 / 2.5MHz = 400 nanoseconds (t is the basic beat of computer operation), and its shortest instruction execution time is 4T = 4 × If 400 ns = 1.6 ns, the operation speed is:
