Dec computing power

POW: full name of proof of work

pos: proof of stake

both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency

the difference is:

1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power

POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbers

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

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 the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography 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

2. There are numerous counterfeit currencies made in China, among which Yuanbao coin, bitcoin, Zhaocai coin and bitstock are well-known

3. If the platform is opened for trading, Dec will become the form of shares, and it can also have the opportunity to trade on the virtual platform. The current 100 Dec may be worth 1 million RBM in the future. It doesn't necessarily depend on the future operation of the platform

According to reports, with the speculation of bitcoin, China's domestic virtual currencies have become popular. They are uniformly called "Shanzhai coins" in the instry, with more than 30 kinds

instry insiders said that the original purpose of virtual currency is financial innovation, to get rid of the traditional currency exchange and payment mode, which is worth affirming. But now, with the rampant of "counterfeit money" in China, it is replaced by investment, speculation, and even illegal phenomena such as money collection

but a variety of digital currencies emerge in endlessly, and there are more and more pyramid schemes of "Shanzhai currency" holding high the banner of virtual currency. In 2017 alone, among a number of major cases investigated and dealt with by local public security organs according to law, 107 currencies are involved, and the amount involved is usually more than 100 million yuan

5. Do you mean virtual currency like BTC and counterfeit currency like LTC? At present, the country has not explicitly stipulated that the Internet virtual currency is illegal, nor has it been recognized as legal. Now it belongs to the gray zone. However, many foreign countries have used virtual currency to trade goods, because virtual currency is used for Internet, and there is no need to convert us dollar or euro. If you feel satisfied, please give me some dog money

6. < UL >

it's hard to say which one is reliable, so let me give you some suggestions. < br > < br >

first of all, the most basic thing is to check whether the platform has published the information of the operation subject, whether it has been put on record, whether it has not been directly shot, and whether it is absolutely a platform to circle money and run away.
Second, check the company's background, whether it has operation experience and strong technical and financial strength,
third Understand that the currency investment on the operation platform is not transparent, and those who are not transparent are directly shot,
Fourth, understand the popularity of the platform through the official QQ group, not to say that it's just lively, but to carefully see if the real players are communicating

The supercomputer on the computer refers to the supercomputer, refers to the volume, computing power

supercomputer has a strong ability to calculate and process data, which is characterized by high speed and large capacity, equipped with a variety of external and peripheral devices and rich and high-function software system

the fastest, highest performance, largest volume and most expensive computer system in supercomputer. Supercomputer is a relative concept. Supercomputers in one period may become ordinary computers in the next period; Supercomputer technology in one period may become general computer technology in the next

supercomputers are mainly used in military technology and advanced scientific research, such as missile and rocket design, spacecraft navigation, high energy physics and genetic engineering. For example, in the process of launching a spaceship, a supercomputer must be used to control the operation of the spaceship in real time

extended data

supercomputer types:

1, "single instruction flow single data flow" system. This is a stand-alone system, the working principle of which is similar to that of the early computers, with the main memory as the center. According to this architecture, large stand-alone systems such as IBM 360-85, IBM 370-195 and mu-5 have been developed

2, "multi instruction flow multi data flow" system. This is a multiprocessor system, which allows several tasks or independent parts of a task to be computed simultaneously on several processors. One of the main forms of this type is the so-called multi bus memory system. Each memory has more than one access port. In order to solve the conflict caused by simultaneous access, an access control circuit is added

3, "single instruction flow multi data flow" system. In order to make the speed of computer system reach tens of millions and hundreds of millions of times per second, it is necessary to improve the parallel degree of computer system architecture“ The system of "single instruction stream and multi data stream" is based on the concept of "parallel computing"

8. What's the concept of two red dragons for one person? Do you think you have a chance to get it? Many people say that they want a 2000 + or so. I see that some promoters have pulled hundreds of people, but they are still pulling people. They don't disclose their progress. When they watch the video later, or how few new people are added, don't waste time. The money of dinosaurs depends on this kind of money. You think it's fake
