this is mainly e to the 51% attack, because before some of the world's well-known mines, e to the low rate and convenient use, many miners went to those large mines to mine. As a result, the computing power of the mines soared, approaching or even exceeding 51% of the global computing power many times

bitcoin community has also raised a big discussion about 51% attack for many times,. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds

most of the new miners have joined the fish pond because they don't know about the global mine ponds, and many of the previous mines have died e to poor management

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

3. We can't go up. We didn't even make a public announcement. It's wrong of us

4. Because you haven't set the key parameters, you are still digging for bitcoin. You can take a look at this tutorial: http://wenku..com/view/0e738530bb68a98271fefacf.html

5. 1. Go to f2pool to register an account. The miner interface has the mining address and miner name
2. Log in the miner (Avalon, roasted cat, ant, miner of different brands and models have different IP addresses. If you find the model, search online), delete the old mine pool in the configuration interface, and fill in the new mining address and miner name
3. Log in to the f2pool miner interface and observe the calculation power. If there is no calculation power, check whether the second step is correct (be sure to delete the previous one, otherwise you are working for others)

6. Caiyunbit's original creation is endless

unknowingly, it came to 2014, with several Avalon generation USB mining machines in hand. You're right. It's not a roasted cat USB miner or any other chip. It's a USB miner of Avalon generation, with a single computing power of about 300m. Of course, the USB mining machine with more than 300 m computing power is of little practical value. It's just a souvenir for everyone<

first, the appearance
first, let's look at the appearance. The workmanship is regular, not exquisite, but slightly rough:

Second, the required software
let's start running cgminer to see how to use it in practice. Before starting work, you need to download three softwares:
1. Cgminer. Anyway, the latest version of 3.9.0 is also available for testing, http://ck.kolivas.org/apps/cgminer/
2. Zadig. This software is needed to replace the driver later. Download it from the same directory as cgminer

3. USB driver of mining machine, http://www.silabs.com/procts/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

3. Install and run

after downloading the above software, start to install and run
1. Insert the USB miner first, and you will be prompted to find the new hardware, and then complete the driver installation according to the prompts

2. After the driver is installed, you can see the new things in the device manager

3. Run Zadig, first click options -- list all devices, then drop down to select port, and replace the driver silabser (v6.6.1.0) with the driver WinUsb (v6.1.7600.16385) recognized by cgminer. After this step is completed, it is recommended to restart the computer

4. Create a new batch file in the cgminer directory, The following command: cgminer - O pool address - U miner name - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: number of mining machines
there are six USB mining machine fish pools, for example: cgminer - O stratum+ tcp://stratum.f2pool.com : 3333 - U AAAA. 2 - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: 6
since cgminer3.2.0, The method of supporting USB mining machine is modified, which does not need to add the - S - com parameter

5, run batch processing, and start to display mining data, about 300m, which is basically normal.

7. Renren mine brand is older, the strength of investors is better, there are mines in the world, and the risk is greater than Xiaolu

8. The computing power of the graphics card is unchanged, but the difficulty of mining is changed. The improvement of the computing power leads to the increase of the difficulty. If you want to maintain the original output, you can only add the graphics card, there is no other way.

9. blockchain is in its infancy, but it is still hindered by bad public relations and regulation. A global digital currency is likely to emerge in 2020. The first jurisdiction to accept the blockchain and develop a regulatory model will benefit from employment and economic growth
in 2019, the blockchain revolution will stagnate. At least that's what those who understand say. A recent Gartner Group report called it "blockchain fatigue.". Other experts also agree with the view that the pilot has failed, few of them have been put into proction, and blockchain may be an edge technology.
