Blockchain geek

2. Blockchain is a technology, and the underlying technology of bitcoin is blockchain. Blockchain features: decentralization, anonymity, security, transparency, traceability, irreversibility, etc
according to the development of blockchain, it can be divided into three stages:
blockchain 1.0 stage: when the digital currency represented by bitcoin first appeared, it was probably from 2008 to 2014
blockchain 2.0 stage: from the birth of Ethereum to the eve of "94 event" in 2017, this is the development era of smart contract and blockchain
blockchain stage 3.0: after the "94 event", we began to pay attention to the exploration and development of blockchain applications and reshape the technology and value of blockchain

although blockchain technology has been widely recognized, people still cannot do without digital currency. After all, the underlying technology of digital currency is blockchain. Even though the non currency blockchain on the alliance chain can be advocated by mainstream regulators, it is much more difficult than the real decentralized blockchain such as public chain projects. What technology geeks pursue are often more difficult decentralized projects

therefore, digital currency will not be destroyed, which is the development trend. As for how you say to play, maybe you are asking how to play digital currency instead of blockchain? If you really want to deepen the understanding, you may as well go to Citex (big C network) to have a look, hope to adopt, thank you.

3. Blockchain technology has been basically mature, and now it mainly focuses on landing applications
on the ground, there will be different solutions according to different instry needs
for example, in the financial instry, relevant financial technology companies have studied and applied it for a long time. Recently, there is a one account chain platform, which is released by Ping An's financial one account link company. It is the solution of blockchain in the financial instry. According to the introction, it has broken through the bottleneck in the implementation process.

4. 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.

5. Setup error, reset

6. Geek wallet is pretty good and very safe. It adopts bip44 mnemonics, local private key, offline signature and other security mechanisms, as well as mobile phone and computer al backup strategy to completely solve the loss of digital currency assets caused by hacker attack, virus infection, mobile phone loss, forgetting mnemonics and other ways, and provides users with online Multi Chain digital assets one-stop management service.

7. Yes, it's very good. The page style is very simple, the operation is simple, and the safety factor is also very high. BTC, ETH, EOS, LTC, usdt, tusd, erc-20 series of tokens are supported by most mainstream currencies. I use a lot when I transfer to usdt, and the transfer is very fast. I need to use BTC to pay the handling charge when I transfer to usdt,
