　　What do you need to prepare before mining?

　　You only need to prepare a DigitalOcean account and a software similar to SSH terminal, such as PuTTY.

　　Digital Ocean account registration.

　　Figure 1: You can query the number and specific location of NKN test network nodes in real time through http://testnet.nkn.org/network

　　Before we start configuring the first mining machine in the pool, we must prepare a Digital Ocean account and then set up a Droplet cloud server.

　　Log in (https://m.do.co/c/b563e65bce71), select ‘Directly log in to DigitalOcean account’ or ‘Register a new account’ according to Figure 2

　　Figure 2: DigitalOcean login interface

　　Figure 3: Enter the necessary information for account registration

　　Enter the username, Email address, and the password you created in turn according to Figure 3 and Figure 4, and finally click ‘Sign Up’ to register. After clicking the registration button, you will enter the DigitalOcean page and be prompted that a registration confirmation email has been sent to your registration Email address. At this time, you need to log in to your own Email account, find that confirmation email, click the registration link in the email to confirm the email address and complete the DigitalOcean account registration process. The link in the email will directly jump to the DigitalOcean account web page to fill in payment information. You need to bind your own credit card or bind a Paypal (Beibao) account. This process is only to add a payment method to your account. DigitalOcean will not charge you before you start using the service. You can start using it after completing the minimum recharge of 5 US dollars.

　　Figure 4: After registering DigitalOcean, you need to recharge 5 US dollars to use the Droplet cloud server

　　Download and install Putty SSH terminal software

　　You can choose the appropriate Putty installation file according to your own computer operating system, and the download link is as follows:

　　https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

　　MSI Windows installation program

　　32-bit: putty-0.70-installer.msi

　　64-bit: putty-64bit-0.70-installer.msi

　　Unix version source code package

　　.tar.gz: putty-0.70.tar.gz

　　Second, configure Droplet cloud server

　　After completing the DigitalOcean account recharge and installing the Putty terminal tool, we can start configuring a Droplet cloud server. As shown in Figure 5, click on the account name after recharge, select the green ‘Create’ menu in the upper right corner of the page, select the first item ‘Droplets’, and click to create a Droplet cloud server for mining.

　　Figure 5: Create Droplet cloud server

　　After completing Figure 5, scroll down the page to see the following configuration options. Here, we only need to configure the following 4 options as shown in Figure 6.

　　Select Linux image version (CentOS 7.5 X64)

　　Select cloud server configuration (lowest configuration)

　　Select the region where the data center is located (select arbitrarily, no requirements)

　　Enter the host name to create a cloud server (set arbitrarily, no requirements)

　　Figure 6: Select Linux image version when creating Droplet cloud server

　　As shown in Figure 6, we need to select the CentOS Linux image, version 7.5 x64. Next, configure the hardware parameters as shown in Figure 7. The NKN mining machine itself has very low hardware requirements due to its unique algorithm design, so we can choose the lowest configuration provided by DigitalOcean, which is 1GB of memory, 1vCPU, and 25GB of solid-state drive. This can control the mining cost of the NKN test network, which is $5 per cloud server per month. Since the NKN mining machine can be set up for 7×24-hour unattended mining, the mining cost per hour is 7 cents, approximately 4 cents and 7厘 in Renminbi per hour.sports betting method and The most exciting gameplay

　　Figure 7: Configure hardware parameters of Droplet cloud server

　　As shown in Figure 8, DigitalOcean’s data centers are distributed in 7 countries around the world, so when you create a Droplet cloud server, you need to select its data center. For NKN mining, it is an open-source community activity with global participation, so there are no requirements for physical location.

　　Figure 8: Select the location of the Droplet cloud server’s data center

　　After completing the above configuration, the configuration of a Droplet cloud server is basically complete. You just need to enter a host name as shown in Figure 9 to distinguish the multiple cloud servers created later.

　　Figure 9: After naming the Droplet cloud server, click “Create” to create the cloud server.

　　After clicking the “Create” button to create the Droplet cloud server, the interface will switch to the installation and configuration progress bar of the server. Generally, you only need to wait for about ten or twenty seconds for it to complete, and you will obtain a public IP address allocated to the server, as shown in Figure 10. This public IP address will be the web address of the NKN testnet miner configuration page in the future, please remember and keep it safe.

　　Figure 10: It takes about ten or twenty seconds to complete the automatic configuration of the Droplet cloud server, which will display the public IP address of the server.

　　So far, we have completed the configuration work of a Droplet cloud server. Next, we need to install the miner on this cloud server. In principle, one Droplet can install one NKN testnet miner. However, one Digital Ocean account can configure many Droplet cloud servers, allowing you to install multiple NKN miners and set up your private NKN testnet micro-mining pool.

　　After you complete the configuration of the Droplet cloud server, you will receive an email from Digital Ocean reminding you of the creation of the cloud server, titled “Your New Droplet: Your Droplet Hostname.” This email will contain the necessary information needed to configure the NKN testnet miner, including the public IP address, username, and initial password, as shown in Figure 11.

　　Figure 11: You will receive a DO email in your registered email address, which contains the username and initial password.

　　After receiving the necessary information in the email, you can open the pre-installed PuTTY software (if you are using MacOS, you can use the terminal SSH), enter the obtained public IP address, and left-click “Open”, as shown in Figure 12.

　　Figure 12: Open the Putty terminal software, enter the public IP address of the Droplet cloud server and click “Open”.

　　If you are using PuTTY for the first time, a warning prompt box will pop up, you can directly click “Yes” to confirm, as shown in Figure 13.

　　Figure 13: After the first click on “Open”, a warning box will appear, click “Yes” directly.

　　This will allow you to enter the command line operation steps, as shown in Figure 14, a total of 13 steps, with the specific operation of each step being:

　　Enter the username: “root” after the “login as” prompt, and then press Enter.

　　Enter the initial password after the “password:” prompt. Note that the password will not be displayed and is only allowed to be a combination of English letters and numbers. If you are using a Windows system, you can copy the password using Ctrl+C and paste it in the PuTTY command line by right-clicking.

　　Enter the initial password again, note that the password will not be displayed.

　　Enter your newly created password, note that the password will not be displayed, and it is only allowed to be a combination of letters and numbers.

　　Enter your newly created password again, note that the password will not be displayed.

　　After successfully setting the password and pressing Enter, you will see the cursor.

　　Enter the following command and press Enter to install the wget software on CentOS: yum install wget -y

　　Enter the following command and press Enter to install unzip on CentOS: yum install unzip -y

　　Enter the following command and press Enter to download the NKN miner software from Github: wget https://github.com/nknorg/nkn-mining/releases/download/v0.0.4/NKNMining-linux.zip

　　Enter the following command and press Enter to unzip the NKN miner software locally: unzip NKNMining-linux.zip

　　Enter the following command and press Enter to enter the NKN miner directory: cd NKNMining-linux

　　Enter the following command and press Enter twice to obtain the serial number: https://www.jb51.net/blockchain/NKNMining

　　The serial number is displayed in the following format, and it should be copied and pasted for future use. NKN-43d3cd9c-d5c3-11e8-98d4-f646aabe0226 (This is just an example of a serial number)

　　Figure 14: Enter the corresponding command in the Putty terminal to complete the miner installationonline casino help and Just click to enter

　　After completing the above 13 steps, the NKN testnet miner installation is complete. Next, we need to go to the web interface to configure the miner account.

　　Firstly, you need to enter the address of the Droplet cloud server you created in the web browser in the following format:

　　http://Droplet public IP:8181/web/

　　In this example, our public IP address is 68.183.76.125, so the address of the miner page is:

　　http://68.183.76.125:8181/web/

　　As shown in Figure 15, after entering the address and pressing Enter, you can see the miner interface. The first step is to fill in the mining account name and mining password, confirm the mining password, enter the serial number obtained from Figure 14, and then click ‘NEXT’ to proceed to the next step, as shown in Figure 16.

　　Figure 15: Open the Droplet cloud server mining page using a web browser at the corresponding public IP address

　　In Figure 16, this is the second step of the mining node configuration page: generate an NKN testnet wallet. You need to create a wallet password and confirm the password again. It should be noted that the password format only allows combinations of English letters and numbers. In addition, if you already have an NKN testnet wallet and want all the NKN tokens mined to be placed in one wallet, you can import the existing NKN testnet wallet through ‘Load wallet’. After completion, click ‘NEXT’ to proceed to the next step.

　　Figure 16: Create an NKN testnet wallet and set a password

　　In Figure 17, it will display the private key and address of the wallet you created. Please keep it properly. Click ‘Download wallet’ to save the wallet locally. After completing, you can click ‘Sign in’ to log in to the wallet page.

　　Figure 17: Displaying the private key and wallet address, you can download the NKN testnet wallet file to local storage

　　As shown in Figure 18, the NKN testnet wallet page is the mining page, which contains a very obvious ‘Node connect’ switch. When you set the switch status to ‘on’, the NKN testnet mining machine starts to operate normally, begins to participate in blockchain consensus, and has the opportunity to receive system rewards. At the same time, the NKN testnet wallet page also contains other testnet status information, such as the height of the testnet blockchain, the current height of your mining machine, wallet address, NKN balance in the wallet, and the ID, IP address, and port number of the neighboring nodes connected to your mining machine, etc. On the right side is the detailed record of the NKN tokens you earn each time you mine. You can also transfer through ‘transfer’ or download the wallet through ‘download’.

　　Figure 18: Operation and query page of NKN testnet mining machine

　　Up to this point, your first NKN testnet mining machine has started to run. If you want to carry out large-scale mining, you can repeat the steps from Figure 5 to Figure 18 to create multiple NKN mining machines to form a micro-mining pool for NKN testnet experimental mining. For example, Figure 19 can be used to view the number and geographical location of the NKN testnet mining pool in real time by clicking on the link (http://testnet.nkn.org/network).
