Chaosnet Darknode FAQ
Tips and Reminders 1) Follow the installation instructions explicitly and you won't have any troubles with installation. 2) Keep your AWS and DO accounts locked down as securely as possible. Use 2FA to login and make sure your password is long. The machine that you used to run the Darknode CLI has all of the access keys that you will need to continue to manage your Darknode. You must not lose these keys. 3) Do NOT send REN to your Darknode, you need to register it using the Command Center (CC). You are interacting with a smart contract, the easiest way to make this interaction with a smart contract is through MetaMask. 4) MetaMask is the only way to interact with the Command Center (CC). We encourage you to get familiar with the product if you are not already: https://metamask.io/
What is the purpose of a Darknode? Darknodes provide the engine that powers the Ren ecosystem. Ren is powered by a decentralized network of machines, called Darknodes, that contribute their compute power and storage space in exchange for fees. Darknodes are the physical machines, where every machine contributes CPU time for compute power and its disk space for storage.

What happens to my bond if I deactivate my droplet/AWS instance before deregistering my node? 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.
Can I use a Hardware Wallet to interact with the Command Center (CC)? Yes, if using a Hardware wallet you can Utilize it via Metamask. Make sure it is set to “contract data => yes” in the ledger Ethereum application settings on your device.
Is the private key of the Darknode on the local system encrypted? No, but it will be possible to add this at a later date.
What happens to slashed REN bonds, if my Darknode act maliciously? The slasher gets a portion and the rest is burned. The entity that noticed the malicious behavior and pointed it out to the blockchain is the slasher. Slashing is reserved for corrupting a computation or correctly verifying a bad proof.
