Can tokens be used for mining
Some new virtual digital coins can be mined by computer, such as eth, Zec, Monroe, XRB, etc
because the whole network computing power required by this kind of token is not high, the probability of hash collision of the computing power of personal computer can find out the answer in a short time, so as to obtain the block reward. However, this kind of token generally has little value, or has no high risk, so it doesn't mean much
extended data:
mining risk:
1. Electricity charge:
to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure:
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and mining has a considerable expenditure
in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display to compete with these mining machines, This kind of machine costs more
3. Currency security:
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
4. System risk:
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income
however, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
many new users believe that the sole purpose of mining is to generate ether in a way that does not require a central issuer (see our guide "what is ether?"). It's true. The token of Ethereum is proced in the process of mining, with a mining rate of 5 Ethereum coins per piece. But mining is at least as important. Usually, banks are responsible for keeping accurate records of transactions. They make sure that money is not created out of thin air and that users don't cheat and spend money many times. However, blockchain introces a new way to keep records, the whole network instead of intermediary, to verify transactions and add them to the public ledger
Ethereum mining
although "no trust" or "trust minimization" monetary system is the goal, there are still people who need to ensure the security of financial records and ensure that no one cheats. Mining is one of the innovations that makes decentralized records possible. Miners have reached a consensus on the history of transactions in terms of preventing fraud (especially double spending on ether) - an interesting issue that hasn't been addressed before the decentralized currency works on the blockchain. While Ethereum is looking at other ways to reach a consensus on the effectiveness of the deal, mining currently keeps the platform together
how mining works
today, the mining process of Ethereum is almost the same as that of bitcoin. For each transaction, the miner can use the computer to guess the answer repeatedly and quickly until one of them wins. More specifically, the miner will run the unique header metadata (including time stamp and software version) of the block through the hash function (which will return a fixed length, unordered string of numbers and letters, which appears to be random), changing only the 'nonce value', which will affect the hash value of the result
if the miner finds a hash that matches the current target, the miner will be granted ether and broadcast the block across the network for each node to verify and add to their own ledger . If miner B finds the hash, miner a stops working on the current block and repeats the process for the next block. It's hard for miners to cheat in this game. There is no way to fake the work and come up with the right answer to the puzzle. That's why solving puzzles is called "proof of work."
on the other hand, others have little time to verify whether the hash value is correct, which is exactly what each node does. About every 12-15 seconds, a miner finds a stone. If the miner starts to solve the puzzle faster or slower than this, the algorithm will automatically re adjust the difficulty of the problem so that the miner can rebound to about 12 seconds of solution time
miners earn these ethers randomly, and their profitability depends on their luck and the computing power they put in. The specific workload verification algorithm used by Ethereum is called "ethash", which aims to require more memory, making it difficult to mine with expensive ASIC. Special mining chips are now the only profitable way to mine bitcoin
in a sense, ethash may have achieved this goal successfully, because dedicated ASIC is not available for Ethereum (at least not yet). In addition, as Ethereum aims to shift from proof of work mining to "proof of equity" (which we will discuss below), buying ASIC may not be a wise choice because it may not prove useful for a long time< However, Ethereum may never need miners. Developers plan to abandon proof of work, the algorithm currently used by the network to determine which transactions are valid and protect them from tampering to support proof of equity, which is guaranteed by token owners. If and when the algorithm is launched, proof of equity can become a means to achieve distributed consensus, and the consensus uses less resources.
"Transaction is mining" is a typical platform operation mode. Users mine through transactions. Some platforms will issue their own tokens as rewards for users' trading behavior
Relevant introction:in June 2018, the cryptocurrency exchange fcoin put forward the concept of "trading is mining", and in a short period of time, the daily trading volume rose to the first in the world, triggering a war between exchanges
"transaction is mining" is actually a return mechanism of personal transaction fees based on platform currency. Strictly speaking, there were similar playing methods before the establishment of fcoin. For example, bibox had a mechanism to return a certain proportion of fee income to platform currency holders
extended data
fcoin's "transaction is mining" is repackaged. Following the allocation rules of bitcoin mining, 51% of platform currency ft is taken as the mining reward pool. Through "mining (trading on fcoin)", FT is graally unlocked. Once 51% of FT is fully fed back, "mining" is automatically terminated
in terms of specific implementation, fcoin trading means mining starts at 0 o'clock every day (GMT + 8), and the transaction fees generated by users will be converted into ft for accumulation every hour. The conversion price is calculated according to the average price of FT in that hour (the average price is calculated as total transaction amount / total trading volume)
It's not against the law
The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract
3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward
Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed
extended information:
according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "
from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all
1. B2B (also written as BTB, which is the abbreviation of business to business) refers to the business model in which enterprises exchange and transfer data and information and carry out trading activities through private network or Internet. It combines intranet and procts and services with customers through B2B website or mobile client, and provides better services for customers through rapid response of network, so as to promote the business development of enterprises
2. B2C is the abbreviation of business to customer, and its Chinese abbreviation is "business to customer"“ "Business to customer" is a mode of e-commerce, that is, the retail mode of selling procts and services directly to consumers
3. C2C is actually a professional term of e-commerce, which is the e-commerce between indivials. Where C refers to the consumer, because the English word of the consumer is customer (consumer), so it is abbreviated as C, and because the pronunciation of 2 in English is the same as to, so C to C is abbreviated as C2C. C2C is customer (consumer) to customer (consumer). C2C means the e-commerce behavior among consumers. For example, a consumer has a computer, through the network transactions, it sold to another consumer, this type of transaction is called C2C e-commerce
B2B has three treasures: enterprise, intermediary, communication,
B2C has three treasures: brand, channel, sales,
C2C, there are three treasures: you open, I buy, Alipay
above is a brief introction about B2B, B2C, C2C market what is the meaning of this, through the introction of this article, we should have a certain understanding of these models, and hope to help everyone.
1. They need to pay entry fees
2. Need to constantly find partners, and set up a team under the guise of doubling income to ince others
3. Decide how much you will get in return according to the number of people below and their business performance< Article 7 of the regulations on the prohibition of pyramid selling of the State Council is an act of pyramid selling:
(1) organizers or business operators, through development personnel, require the developed personnel to develop other personnel to join, To calculate and pay remuneration (including material rewards and other economic benefits, the same below) to the developing personnel based on the number of the personnel they have directly or indirectly developed in a rolling way, so as to seek illegal benefits
(2) the organizer or business operator, through the developer, requires the developed person to pay fees or pay fees in disguised form by way of subscribing for commodities, so as to obtain the qualification of joining or developing other persons to join and seek illegal interests
(3) the organizer or business operator, through the development personnel, requests other personnel developed by the development personnel to join, forms the relationship between the upper and lower line, and calculates and pays the online remuneration based on the sales performance of the lower line, so as to seek illegal interests.
2 is to, which means right
C is customer, customer, consumer
B2C refers to a mode of e-commerce, namely "business to indivial", such as aidongxi.com and excellence.com; Corresponding is C2C, namely "indivial to indivial", typical such as Taobao
the development of B2C in China is just at the beginning. The traditional C2C model is limited because of the crucial credit problem. Compared with indivials, consumers trust businesses or companies, so B2C is quite a large supermarket, And C2C is a business district composed of private stalls
at present, domestic B2C Websites mainly include aidongxi, Zhuoyue Amazon, Dangdang, Xindan, etc.
C2C Websites mainly include Taobao, paipai, YOUAH, eBay, etc.
