​

Here's a quick start start script for 32bit Raspberry Pi OS that you can run that automates the instructions below to download and copy all files and start the Hydra wallet in daemon Mainnet mode:

wget -O - https://raw.githubusercontent.com/meshungina/hydra/main/install-run-gui-wallet-pi.sh | bash

Once done please see: Getting information through the cli​

​

Manual installation:

Step 1 - Download

Before starting ensure that your system is up to date by executing:

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils git cmake libboost-all-dev libgmp3-dev
sudo apt-get install software-properties-common
sudo apt-get update
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler qrencode

Select the latest wallet version from the link below:

​Latest Releases​

Here you will find wallets for different types of operating systems. You will need to download the arm-linux version for your Raspberry.

Create a directory called Hydra and download the zip file to it:

mkdir ~/Hydra
cd ~/Hydra/
wget -N https://github.com/Hydra-Chain/node/releases/download/hydra_v0.18.5.5/hydra-0.18.5.5-arm-linux-gnueabihf.zip

​

Step 2 - Unzip

Extract the archive

unzip -o hydra-0.18.5.5-arm-linux-gnueabihf.zip

Step 2b - Copy config file

Create ~/.hydra folder then and copy the hydra.conf from the current directory into it.

mkdir ~/.hydra
cp ~/Hydra/hydra.conf ~/.hydra

​

Step 3 - Run

The binaries will then be in ~/Hydra/bin/ where you can cd into with

cd ~/Hydra/bin/ 

Either run the command-line daemon (add '-testnet' if you wish to connect to testnet):

./hydrad -daemon

Call the daemon using(add '-testnet' if you are connected to testnet):

./hydra-cli getinfo

Or you can run the GUI(add '-testnet' if you are connecting to testnet):

./hydra-qt

If you are updating your node and experience issues try starting with these flags to rebuild:

 -rescan -reindex

If you are experiencing errors with libboost you can try fixing it with these commands:

sudo apt-get update
sudo apt upgrade -y
sudo apt-get install git autoconf libtool libboost-dev libboost-system-dev libboost-filesystem-dev libboost-thread-dev libboost-chrono-dev libboost-random-dev libssl-dev libevent-dev libboost-test-dev

Setup for 64 bit Ubuntu Desktop 20.10 for pi

Here's a quick start script for Arm 64 bit devices. You can run that automates the instructions below to download and copy all files and run the Hydra wallet daemon in Mainnet:

wget -O - https://raw.githubusercontent.com/meshungina/hydra/main/install-run-gui-wallet.20.10PI64.sh | bash

Manual installation

Step 1 - Download

Before starting ensure that your system is up to date:

sudo apt update -y
sudo apt upgrade -y
sudo apt -y install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils git cmake libboost-all-dev libgmp3-dev libzmq3-dev
sudo apt-get -y install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler qrencode

Select the latest wallet version from the link below:

​Latest Releases​

Here you will find wallets for different types of operating systems. You will need to download the aarch64 version for your Raspberry or other arm device running 64 bit OS.

Create a directory called Hydra and download the zip file to it:

mkdir ~/Hydra
wget -N https://github.com/Hydra-Chain/node/releases/download/hydra_v0.18.5.5/hydra-0.18.5.5-aarch64-linux-gnu.zip -P ~/Hydra

​

Step 2 - Unzip

Extract the archive

unzip -o hydra-0.18.5.5-aarch64-linux-gnu.zip

Step 2b - Copy config file

Create .hydra folder and copy the hydra.conf file into it.

mkdir ~/.hydra
cp ~/Hydra/hydra.conf ~/.hydra

You can now navigate to where the Hydra binaries are to initialize them:

Step 3 - Run

If you have unzipped the file in the ~/hydra folder the binaries will then be in ~/Hydra/bin/ where you can cd into with

cd ~/Hydra/bin/ 

Either run the command-line daemon (add '-testnet' if you want to connect to testnet):

./hydrad -daemon

Call the daemon using(add'-testnet' if you are connected to testnet)::

./hydra-cli getinfo

Or you can run the GUI(add '-testnet' if you want to connect to testnet):

./hydra-qt

It is recommended when updating binaries to start with these additional flags the first time:

-rescan -reindex

If you are experiencing errors with libboost you can try fixing it with these commands:

sudo apt-get update
sudo apt upgrade -y
sudo apt-get install git autoconf libtool libboost-dev libboost-system-dev libboost-filesystem-dev libboost-thread-dev libboost-chrono-dev libboost-random-dev libssl-dev libevent-dev libboost-test-dev

Getting information through the cli

General wallet information balance/staking

You can view your Coin balance and amount currently staked with the following command:

./hydra-cli getwalletinfo

Retrieving your LOC token balance through the cli:

This is slightly involved, first we'll need to find out the HEX equivalent of our address. We can do this through the cli with this command:

./hydra-cli gethexaddress <YOURADDRESS>

We can then call the contract with the "getbalance" identifier appended, which is 70a08231and replacing the last part <YOURHEXADDRESS> with your own hex address here:

./hydra-cli callcontract 4ab26aaa1803daa638910d71075c06386e391147 70a08231000000000000000000000000<YOURHEXADDRESS> | grep -e "output"

Finally convert the "output" section of the response from hex to decimal to arrive at your LOC balance.

echo $((0x<YOUROUTPUT>))

Below is a full example:

Time until expected block creation

To see expected time enter the following command:

./hydra-cli getstakinginfo

Note below the section "expectedtime".

The "expectedtime" can be converted to human readable format using the following command (replace 1254588 with your expectedtime value:

date -u -d "@1254588" "+Estimated time to mine next block in: %d days %H hours %M minutes"
