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

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. Hello, velcoin is a new virtual currency... You can't find any valuable information on the Internet, and you can't find any relevant information on the official website of the State Administration for Instry and Commerce... In other words, it's not protected by law. How high is the risk? You know... Crisis is the coexistence of risk and opportunity... Investment or not? It's still up to you!

4. Generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. For example: at present, I have an account book, which is my system to keep accounts. The account book of wechat is Tencent in memory, and the account book of Taobao is Ali in memory. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology

RGB color mode is a color standard in the instry. It obtains various colors by changing the three color channels of red (R), green (g) and blue (b) and superimposing them. RGB is the color representing the three channels of red, green and blue. This standard covers almost all the colors that human vision can perceive, It is one of the most widely used color systems

extended data:

principle

RGB is designed according to the principle of color luminescence. Generally speaking, its color mixing method is like red, green and blue lights. When their light overlaps with each other, the colors are mixed, but the brightness is equal to the sum of the three brightness. The more mixed, the higher the brightness, that is, additive mixing

for the superposition of red, green and blue lights, the brightest superposition area of the central three colors is white, and the characteristics of additive mixing: the more superposition, the brighter

red, green and blue are three color channels. Each color is divided into 256 levels of brightness. At 0, the "light" is the weakest - it is turned off, and at 255, the "light" is the brightest. When the three color gray values are the same, the gray tone with different gray values will be proced, that is, when the three color gray values are all 0, it is the darkest black tone; When the three color grayscale is 255, it is the brightest white tone

RGB colors are called additive colors because you can proce white by adding R, G, and B together (that is, all light is reflected back to the eye). Additive colors are used for lighting, television and computer displays

for example, displays emit light through red, green, and blue phosphors to proce color. Most visible spectra can be expressed as the mixture of red, green and blue (RGB) light in different proportions and intensities. If these colors overlap, they proce cyan, magenta and yellow

Pyramid selling refers to the behavior that organizers and developers illegally obtain wealth through developing personnel or requiring the developed personnel to pay a certain fee to obtain the qualification of joining. The essence of MLM is "Ponzi scheme", that is to say, the money of later comers is distributed to the income of former comers

the new type of MLM: it does not restrict personal freedom, does not accept ID cards and mobile phones, and does not take big classes collectively. Instead, it uses capital operation as a banner to pull people to cheat money. It uses luxury cars, gold and silver to attract your relatives and friends to join, and finally makes you lose all your money

MLM originated in the United States in the late period of World War II, formed in Japan after World War II, and developed in China

the main concept of MLM in foreign countries is to use the word-of-mouth generated by customers' use of procts as the driving force, let customers help dealers to promote procts and share part of the profits, that is, customer communication sales. This is different from the domestic concept of MLM

when a financial expert exposed Ponzi's investment fraud, Ponzi also published an article in the newspaper to refute financial experts, saying that financial experts knew nothing

In August 1920, Ponzi went bankrupt. The money he received, according to his promise, could buy hundreds of millions of European postal bills. In fact, he only bought two

since then, "Ponzi scheme" has become a special term, which means to use the money of the later "investor" to repay the former "investor"
