1 Cold Masternode Guide Absolute Coin 2018

2 Overview There are 2 possible setup options for a MasterNode: 1 2 Absolute Hot Node Absolute Cold Node 1 2 Absolute Hot Node 1000 ABS are stored as a collateral in a MasterNode Absolute Cold Node - the MasterNode runs on a Virtual Private Server (VPS), while coins are stored locally in your wallet. It is a more secure approach, as the public IP address associated with the MasterNode is not the same as the wallet IP address. In addition, shut down of the wallet does not affect the MasterNode. Prequisities ABS Collateral: The required collateral for the Absolute Master Node setup is 1000 coins. To cover the imposed network transaction fee for a transfer we recommend to have an extra coin. A local wallet: Place where you will store the collateral of 1000 ABS. Windows or linux wallets are accepted. SSH client for your VPS: We recommend Putty client installer.msi

3 MasterNode Seup Procedure 1 Connect to your VPS Terminal with SHH protocol (Putty) Launch Putty and enter your VPS IP address into the Host Name field. Other settings should stay default. We recommend you to save this IP address in Putty. To do so, name it in the Saved Sessions Box and Save. Click Open. You will see a pop-up message with a security alert about the keys. Click Yes. Log in to your VPS. The VPS provider should give you both the username and the password 2 Swap Memory Setup This step is not applicable for VPS with 2 GB or more of RAM. Otherwise, enter the command into the terminal (in Putty press RIGHT CLICK to Paste): dd if=/dev/zero of=/mnt/myswap.swap bs=1m count=4000 mkswap /mnt/myswap.swap

4 chmod 0600 /mnt/myswap.swap swapon /mnt/myswap.swap The afforementioned steps increased Swap memory to 4 GB, which is enough to compile the Absolute Daemon. 3 Absolute Daemon Compilation wget chmod +x install.sh./install.sh This operation is mandatory. Depending on your VPS and internet bandwidth it may may take up to 60 minutes.

5 4 Send the collateral of 1000 ABS & generate private key and transaction hash Generate a new address in your local wallet (NOT the VPS). Label it with MN1. (This label can be given any name you want, but for the purpose of this guide we will call it MN1 ). Transfer EXACTLY 1000 ABS to the newly generated address. Ensure that the Subtract fee from amount box is NOT checked. The transfer requires 15 confirmations before the MasterNode launch. The status of the transaction can be checked in the Overview wallet tab or by double clicking the transaction in the Transactions section. Open the debug console in your local wallet.
