Virtual currency POS

1. bitcoin is still the dominant cryptocurrency, and no currency can surpass it. Most of the start-ups in the field of cryptocurrency are bitcoin related companies. However, the development of bitcoin has also encountered a big bottleneck. The popularity of bitcoin is purely e to speculation and people's psychological expectation, lacking of corresponding commercial application support

compared with other Shanzhai coins, Fuyuan coin is a revolutionary innovation in commercial application. Fuyuan coin is proced in the operation and circulation of the member enterprises of the global jewelry instry association. Users can obtain certain Fuyuan coin by purchasing the jewelry procts of the member cooperative businesses. Fuyuan coin can be purchased in the cooperative businesses or put in the wallet. New Fuyuan coin can be generated through the POS mechanism. Of course, it can also be traded in the free market on the trading platform. This also forms a closed-loop business application system, similar to business points

of course, the ideal is full, the reality is the backbone, the future is bright, and the road is tortuous.

2. virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"
according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, cannot and should not be used as currency in the market, and citizens' investment and transaction of virtual currency are not protected by law

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

4. Virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher; The popular digital currencies in 2013 include bitcoin, Leyte coin, Fuyuan coin, doggy coin and so on
network virtual currency can be roughly divided into

the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.

5. POW: full name of proof of work

What does this mean? That is to say, how much money you get depends on the effective work you contribute to mining. In other words, the better the performance of your computer, the more money you will be allocated. This is to allocate money according to your work certificate. Most virtual currencies, such as bitcoin, Leyte and Ruitai, are based on the pow mode (the higher the computing power and the longer the mining time, the more money you get)

pos: proof of stake

What does that mean? In short, it is a system to pay you interest according to the amount and time of currency you hold. In the POS mode of certificate of equity, there is a term called currency age. Each currency has one currency age every day. For example, if you hold 100 currencies for 30 days, then your currency age is 3000. At this time, if you find a POS block, Your currency age will be cleared to 0. Every time you are cleared 365 coins, you will get interest of 0.05 coins from the block (which can be understood as 5% annual interest rate). In this case, interest = 3000 * 5% / 365 = 0.41 coins, which is very interesting. Holding coins has interest, very good!

6. In line with the rigorous logic of problem-solving, we should first ask whether it is, then why
first of all, the topic is not right. Now there are all kinds of currencies on the exchange, whether it's big platforms like Qube, or small ones like coin an, or competitive ones like Shanzhai coins. They are not all POS models
for example, LTC is a variant of crypt algorithm pow, dogcoin is a variant of pow, and auxpow is a fusion mining algorithm
Dashi coin is the pow of X11 algorithm, Ethereum is the pow of ethash algorithm, and Diandian coin is the pow + POS simultaneous mining. Now the new Shanzhai coin is mostly the early POW + late POS mode, the reason is 1, the early POW is to avoid uneven distribution. 2. In the later stage, POS can't win in the pow competition, but the computing power is low, and POW is easy to be attacked by 51
that is, only from the perspective of security: high computing power pow (including auxpow like dog coin) & gt; POS> Low computing power pow

7. What is BACC from mining

Private key: in fact, it is a group of random numbers. We have already introced the random numbers in the blockchain
public key: the private key is generated by elliptic curve encryption algorithm, but the private key cannot be obtained by public key inversion. The function of public key is to encrypt information with one's own private key when dealing with the other party, and then the other party decrypts the original information with one's own public key. This process is commonly known as signature
address: because the public key is too long and inconvenient to use in the transaction, the public key hash is encrypted with sha256, ripemd160 and base58 algorithms to generate the address

< UL >

first, the random number generator is used to generate a "private key". The subsequent public key and address will be generated by the private key, so the importance of the private key can be summarized in one sentence: & quot; Who has the private key, who has the right to use the wallet& quot;

"private key" is encrypted by elliptic curve algorithm (secp256k1) to generate & #; Public key;. This is an asymmetric one-way encryption algorithm. Knowing the private key can calculate the public key, but knowing the public key can't reverse calculate the private key

< / UL > < UL >

"public key" generates "public key hash"

through one-way hash algorithm (sha256, ripemd160), and connects a byte of address version number to the "public key hash" header (for the pubkey address of bitcoin network, The first four bytes of the result are used as the check value of "public key hash" and connected at the end of it

encode the previous result with base58 (customized version of bitcoin) to get the "wallet address"

9. First of all, you can register a company in Hong Kong of any nationality. Secondly, most of them are not registered in Hong Kong. For example, the famous Biyuan chain, quantum chain, Ethereum and fire coin network are not registered in Hong Kong, most of them are in Singapore. It's also registered in Switzerland
it's very easy to register a Hong Kong company. You only need to provide your ID card and company name. The registration time is 10 to 15 working days. It's very fast.
