POS pool ranking
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
The ranking of domestic filecoin mining pool is relatively clear, but there is no very strict measurement in IPFs field. The basis for judging whether the mining pool is efficient depends on its unit output efficiency! Interstellar infinite has developed the Shensuan mining pool system exclusively, and the mining efficiency has been far ahead of the global mining pool systems
one is completely closed, has nothing to do with real economy and can only be used in specific virtual communities, such as world of warcraft gold
Second, it can be purchased in real currency but not converted back to real currency, which can be used to purchase virtual goods and services, such as Facebook credit
thirdly, it can be exchanged and redeemed with real currency according to a certain ratio. It can purchase both virtual goods and services and real goods and services, such as bitcoin [2]
transaction mode
at this stage, digital currency is more like an investment proct, because of the lack of a strong guarantee agency to maintain its price stability, its role as a value measure has not yet appeared, and it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investors
trading platforms act as trading agents, and some of them act as market makers. The profits of these trading platforms come from investors' transaction or withdrawal fees and premium income from holding digital currency. Bitstamp, gathub, ripple Singapore, snapswap, Japan's Mt. GOx and China's new star Ruihu are the platforms with large trading volume [4]
the process of digital currency trading through the platform is as follows:
(1) investors should first register their accounts and obtain digital currency accounts and US dollar or other foreign exchange accounts
(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures
(3) the trading platform will sort the buy requests and sell requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded
(4) a buy or sell request may be partially executed e to the difference between the buy and sell volumes submitted by users.
