Miner connector

1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
mining machine is a tool for procing and mining bitcoin

Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

3. Miner's moisture is relatively large, the main network code has not been finalized, miner will be determined first. Maybe after the main network goes online, we can't find money. There are also some supercomputing versions on the market, which can be understood as mining machines with a lot more than the normal configuration. This is a good way to deal with the total code changes of filecoin. But certainly not the most cost-effective mining machine. Make a good investigation and wait for you to test in the pit and Yuanli mine.

4. 1. Miner path setting: to link the server of the mine pool
2. Miner name setting format: Mining account number miner number:
if the mining account number is Adrian, multiple miners can be set as Adrian, Adrian... And so on, miners will be arranged in the order of number. Password: you can not fill in or enter at will
3. Mining machine link configuration: get the IP address of the mining machine, log in the same LAN to access the IP address, and then visit the mining machine background to set the mining machine.

5. 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.

6. First of all, park the excavator in a flat place, and it is better to stop overnight, and then start to change the oil the next morning, but do not start the excavator. The advantage of these two points is that the waste oil can be discharged more thoroughly
to change the oil is to remove the screw from the engine oil pan and catch it with a bucket (waste oil can be sold for money). At the same time, you can remove the oil filter. After removing the general oil filter, you can install a new one. There's no need to wait. Just use a paper towel to clean the waste oil on it. It's not necessary to use too much force when installing, so as not to crack tightly. Generally, after the new filter is installed, the engine will be used for one day, and the filter will be tighter after high temperature. When you see that there is no waste oil dripping from the oil drain hole below, you can add new oil. Before adding new oil, you can also add a little to remove the remaining waste oil from the oil pan (almost all engines are difficult to drain all the waste oil at one time). But you can also add all the new oil directly
when adding new oil, you must check the dipstick while adding it, so as not to add too much oil. When you see that the oil has reached the upper end of the dipstick mark, you can generally start the engine. Remember not to use the oil filling door, let it run at a low speed for one minute, and then turn off the engine. After every 30 seconds, when you go to check the oil, the oil is generally a little less than before, Because part of the oil is in the new oil filter, you must add a little oil until the oil reaches the upper end of the dipstick mark. After changing the engine oil, remember to check if there is any oil leakage at the place you just removed. It's better to clean the engine with some water. The water is better not to face the generator and motor to avoid short circuit.

7. 1、 There is an oil indicator cover on the top of the instrial lock. Just screw it down and fill oil directly. Then there is an oil indicator window in front. The oil level should not exceed the second oil level line< (1) always refuel


all oil holes on the machine and all rotating parts should be refueled with clean sewing machine oil every 4 hours. Other oils and unclean sewing machine oil should not be used, so as not to affect the service life of the machine
(2) regular maintenance and inspection
it is necessary to keep the parts clean, regularly check whether the temperature and sound of the rotating parts are normal, and repair them immediately if any problems are found, so as to avoid damaging the machine
generally, minor overhaul is concted once a month, and cleaning and major overhaul are concted once a half year. After being put into use for a long time, it should be cleaned and overhauled first
the thickness and use speed of the sewing material should be selected within the specified range, and it should not be overloaded or over speed.

8. CPU architecture is not very important in IPFs mining machine. Hummingbird H1 mining machine runs Linux operating system

9. What do you want to do with the monitor
there should be many mining machines and one monitor
you need to take a look at them at the beginning of setting
