Q. How do I see my Darknode and where can the Command Center (CC) be located? A: https://mainnet.renproject.io/​

Q: How are the Darknode Fees distributed? It seems total fees are cut in half by 50% and then distributed? A: Correct, Darknode earnings for each Epoch are split 50/50. First 50% goes to the current Darknodes that are active during that Epoch and are claimable. This is why you see The remaining 50% are distributed in subsequent Epoch.

Example: If $10,000 in fees are earned during an Epoch. $ 5,000 are distributed, and the remaining 50% ($5,000) is rolled over into the next epoch. This process is repeated in perpetuity. This is explained in more detail in the Earning rewards section of the User Manual. Q. Does my Darknode auto-claim rewards? A: Yes, if you have ETH Gas in your Darknode. The rewards your Darknode earns each epoch are collected by RenVM and placed into the Darknode Reward Pool contract. At the end of each epoch, your Darknode will automatically claim its share of the rewards. This requires your Darknode to submit a transaction to the Ethereum blockchain and this is what your Darknode requires gas for.

Auto-claiming uses the Gas from your Darknode. Without Gas, the fees are forfeited to the next epoch’s reward pool Q. Does my Darknode NEED to have Gas (ETH) in it at all times? A: Yes, you need Gas (ETH) in your Darknode at all times. If not, your rewards will be redistributed to other Darknodes at the next epoch.

Q.What is the recommended amount of ETH (for GAS) needed for a Darknode? A: 0.1 ETH Q: What are the Darknode rewards withdrawal criteria? A: Once the rewards are claimable, there is no criteria except that the rewards must exceed the minimum blockchain mining fee. This depends on the blockchain but in general, it is not encouraged to withdraw less than 10$ USD or a good majority of it will be eaten by fees. Q: What are the Gas, Blockchain Mining, and RenVM fees for withdrawing rewards? A: These fees apply to any RenVM based transaction, including reward withdrawal. - RenVM = 10 BPS of the amount moved. - Gas (ETH) = Depends on congestion but typically around 2 or 3 USD. - Blockchain Mining = Depends on congestion but typically around 1 USD. Q. Do Darknodes Auto Update? A. No, it is a security risk. If there is a mandatory update needed we will let the Ren Community know via the Telegram Announcement Channel: https://t.me/renprojectann Q: If my Darknode’s VPS has downtime for maintenance, will it get slashed? A: No, the downtime has to exceed 12 + hours for action to be taken.

Q. What version of Linux is supported for Darknode CLI? A: AMD64

Q. What version of Windows is supported for Darknode CLI? A: Windows 10 and newer

Q. What happens to my bond if I deactivate my droplet/AWS instance before deregistering my node? ‌A: You must use the CLI tool to destroy your node. It will not let you destroy your node until the deregistration and bond refunding process is complete. However if you have done this, your funds are safe, but you need to destroy the node using the CLI to ensure all resources are terminated correctly, your node can lose its rewards if it is offline while registered.

Q. Can I use a Hardware Wallet to interact with the Command Center (CC)? A. Yes, if using a Hardware wallet you can utilize it via Metamask. Make sure it is up to date and set to “contract data => yes” in the ledger Ethereum application settings on your device.

Q. Is the private key of the Darknode on the local system encrypted? A: No, but it will be possible to add this at a later date.

Q: Once I’ve launched my Darknode, what can I do while I wait for the next Epoch to begin? A: We recommend immediately topping up your Darknode with Gas (ETH) to ensure your Darknode will auto-claim rewards. The recommended amount of Gas (ETH) is 0.1 ETH.

We also recommend backing up your Darknode folder that is created on your machine when you install the Darknode software via your Command Line Interface/Terminal. For more information on how to do this, read on.

Interacting with your Darknode through the CLI

What is the Darknode CLI? The Darknode Command Line Interface (CLI) is how your physical computer interacts with Darknode that is hosted on a VPS.

‌How do backup my Darknode? Do I need to do anything else besides storing my keys in a safe place? It is recommended you keep a safe copy of your “~/.darknode” folder in addition to storing the keys in a safe place. Directions | Back up your Darknode file by inputting this into your Terminal and pressing enter:

MAC OS

cp -r ~/.darknode ~/Desktop/darknode-backup-2019XXXX

(Note: XXXX= A date of your choice). A backup folder will appear on your desktop/documents folder. Save this folder somewhere safe!

Windows OS via Ubuntu

cp -r .darknode/ /mnt/c/Users/Administrator/Desktop/2019xx

(Note: Replace ‘Administrator’ with their windows username). A backup folder will appear on your desktop/documents folder. Save this folder somewhere safe!

Linux

cp -r ~/.darknode ~/Documents/darknode-backup-2019XXXX

(Note: XXXX= A date of your choice). A backup folder will appear on your desktop/documents folder. Save this folder somewhere safe!

How do I restore my Darknode from a backup folder?

Find your Darknode folder. Once found, swap the following folder: “~/.darknode/darknodes”

Put your old backup folder in the place of the new one. Close the folder and open the CC via a web browser to confirm all information has been ported over correctly.

How To Tell If Your Darknode Is Running Properly? To ensure you Darknode is functioning properly, please run the following command on your computer’s terminal (CLI):

darknode list

Your Darknode name will appear, IP address, etc. in the terminal if running properly. You can also check on the Command Center once registered!
