Newpos pool

1. mining pools are arranged according to computing power. For example, the computing power of digyi mining bitcoin mining pool accounts for about 4% of the total network computing power, ranking among the top ten mining pools in the world. The four technology blockchains are relatively good.

2.

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. In fact, the two models are almost the same, and all platforms can be used, which is better
I think me31 is better, smaller and has a lower failure rate

4. Huarong 8210 upgrade details

note: when upgrading, please plug in the external power, or ensure that the battery power is more than 80%, and the upgrade process can not power down; After upgrading, if there is touch screen configuration, please make sure to calibrate the touch screen

1. Connect the prepared U disk (loaded with the latest firmware file new8210. IMG) and USB OTG cable to the new8210 machine

insert 8210 upgrade 1

2. In the off state, press the "menu", "function" and "confirm" keys at the same time, and then press the power on key

3. When you see "USB update" on the screen, you can release the button; At this time, please wait patiently for the firmware upgrade. After the upgrade is completed, it will restart automatically to complete the upgrade

insert 8210 upgrade 2

attachment: problem solving in the update process:

A. display "start USB... Failed": A. check whether the connecting cable is in good contact; b Try to replace other USB flash drives

B. display "load image... Failed": A. ensure that the downloaded firmware has been renamed new8210.img. The suffix has no version number; b. Check whether the downloaded firmware file is complete, and the size is about 40 MB.

touch screen calibration

after the upgrade, please calibrate the touch screen. This step is for the model with touch screen configuration (electronic signature), if not, it can be ignored

insert 8210 upgrade 3

5. Built in flow card, free for the first six months, three bucks per month from the seventh month

6. Hello, 8210 machine, when sending the chip card, the chip faces up. You can see the slot at the end of the machine

pro, are you satisfied with my answer? If you are satisfied, please accept it! Or you can choose to keep asking me.

7. Hello, it's usually caused by bad signal. You can change the network environment and try again. If not, then contact your service provider to deal with it

pro, are you satisfied with my answer? If you are satisfied, please accept it! Or you can choose to keep asking me.

8. Check in screen will be displayed after power on. Operator input 01 password 0000, the national POS machine basically sign in like this!

9. It depends on what platform. The password of each platform is different.
