Tutorial: Neblio staking wallet for RaspberryPi

A lot of people talking about Neblio blockchain since this coin entered the Top100 cryptocurrency. I don‘t want to talk so much about it‘s pro and cons but more about it‘s very rare Proof-of-Stake protokol and how to participate with your coins.

PoS and Reward

Proof-of-Stake means that you help to secure the network compareable to miners in PoW blockchains. But unlike PoW you don‘t need all this infrastracture. You only need a wallet and your coins.

In case of Neblio you will get a staking reward of 10 % a year. Check out this calculator. You get your reward every time the chance choosed your wallet with your weight of coins to stake a block. Means: Heavy wallets will stake more blocks than light wallets. But in the end everybody gets ~10 % a year.

If you have just a few coins it can take a while until you stake a block. For example: When you have 1000 coins with the current difficulty you will wait around 10-14 days to get your reward.

To stake a wallet you need to be connected to the network. I personally don‘t want to run my computer 24/7. But the Neblio team came up with a easy to use RaspberryPi staking wallet. In this tutorial I want to show you how to install the Neblio wallet.

1. Run RaspberryPi

Switch on your Pi and connect it to the internet. For this tutorial it doesn't matter if you connect with a graphical interface (HDMI) or via a SSH session from remote terminal. Both will work because we use the non-graphical staking wallet from Neblio.

2. Install Wallet

We install the nebliod wallet (non-graphic-interface). Open a terminal in your RaspberryPi and type:

cd /home/pi

assuming your username is "pi". Next step is download and install. We use this code I have from official Neblio Github. Copy into your terminal:

curl https://raw.githubusercontent.com/NeblioTeam/NEBL-Pi/master/NEBL-Pi-Installer.sh | bash -s -- -d

3. Waiting

Now your Pi is downloading/installing the wallet and then sync the blockchain. This will take around 2 hours (with a Raspberry Pi 3) to finish.

4. Wallet file

If you have an existing encrypted wallet file:

Browse to directory /home/pi/.neblio and check if there is a file named wallet.dat. So send your encrypted wallet.dat file to your Pi and replace it with the file in /home/pi/.neblio

If you don't have an existing wallet file (use the wallet in /home/pi/neblio/wallet.dat):

Encrypt you wallet by:

/home/pi/./nebliod encryptwallet passphrase

Replace "passphrase" with your wanted password. Be careful here and don't use special characters since another user said there might be problems with that.

To show your wallet addresses type:

/home/pi/./nebliod listreceivedbyaddress 1 true

5. Unlock wallet for staking

Type in terminal

/home/pi/./nebliod walletpassphrase password 31000000 true

Repalce password in code with your password. The large number is the time your wallet will be open. In this case ~1 year. True means that wallet open for staking.

6. Is wallet staking?

To check if your wallet is staking type

/home/pi/./nebliod getstakinginfo

7. Autostart

This is optional. If you want to autostart your wallet every time your Pi is restarting, this would be one possible solution:

Make sure your user Pi has a password by

sudo su

Then:

sudo passwd pi

Choose a password. Then type:

exit

Now we autostart the wallet by:

nano /etc/rc.local

And paste 3 lines of code

su pi -c"nohup /home/pi/nebliod >/dev/null 2>&1 &"
sleep 600
su pi -c "nohup /home/pi/nebliod walletpassphrase password 31000000 true >/dev/null 2>&1 &"

Again replace word password with your wallet password. Close the editor by Ctrl+X and then Y.

Now your wallet will be open for staking every time you connect plug in the pi.
