Mine pool refers to:

as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network

after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"

extended data:

the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in

but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:

the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network

2. That is, crowdfunding uses bitcoin instead of RMB. PS: at present, domestic ICO is illegal

1、 Market value: refers to the market value. The current market value of a company

Second, calculation method: market value = all the stocks issued by the current company * the sum of the corresponding prices of the current stocks is the market value of the company! It refers to the current price, not the issue price

(1) the total market value of Sinopec is about 607.7 billion, and the circulating market value of a shares is about 30.1 billion, because the national shares of the largest shareholder will not be sold, so they can not be included in the circulating market value for the time being. However, when calculating the index, the market value of 65.758 billion shares is calculated, which should be noted

(2) the total market value and circulating market value will change with the change of stock price. Based on the closing price of a shares on September 23, 2011, the circulating market value of a shares is about 4901535 billion yuan, and the total market value of a shares is about 60778474 billion yuan

financial tips: market value and net assets

4. The net asset value of a fund refers to the balance of the total market value of the fund assets calculated at the fair price after decting the liabilities at a certain time point of fund valuation. The balance is the equity of the fund unit holders. The process of calculating fund assets at fair price is fund valuation
unit fund net asset value refers to the net asset value of each fund unit. The formula for calculating the net asset value of a unit fund is:
net asset value of a unit fund = (total assets total liabilities) / total number of fund units
where total assets refer to the total assets of all assets owned by a fund (including stocks, bonds, bank deposits and other securities) calculated at the permitted price. Total liabilities refer to the liabilities formed ring the operation and financing of the fund, including various expenses payable to others, interest payable, etc. The total number of fund units refers to the total number of fund units issued at that time
fund valuation is the key to calculate the net asset value of a unit fund. Funds tend to invest in various investment tools in the securities market, such as stocks and bonds. Because the market price of these assets is constantly changing, only by recalculating the net asset value of the unit fund every day can the investment value of the fund be reflected in time. The valuation principles of fund assets are as follows:
1. Listed stocks and bonds are calculated according to the closing price on the calculation day. If there is no transaction on that day, they are calculated according to the closing price on the latest trading day
2. Unlisted stocks are calculated at their cost price
3. Unlisted treasury bonds and unmatured time deposits are calculated by the amount of interest accrued from the principal to the valuation date
4. In case of special circumstances, it is impossible or inappropriate to determine the value of assets according to the above provisions, the fund manager shall handle it in accordance with the relevant provisions of the state
the transaction price of closed-end fund is the market price that has been known when the transaction occurs; Different from this, the unit trading price of open-end fund depends on the net asset value of unit fund which is not known at the time of subscription and redemption (but can be calculated after the closing of the market on the same day and announced on the next trading day).
