How run Node?

Update sistem and install node

sudo apt-update
sudo apt-get install -y apt-transport-https ca-certificates

1.1. First remove any previously installed version of the daemon to prevent any errors when upgrading to the latest version.

sudo apt-get remove -y mina-testnet-postake-medium-curves
echo "deb [trusted=yes] http://packages.o1test.net release main" | sudo tee /etc/apt/sources.list.d/mina.list
sudo apt-get update
sudo apt-get install -y curl unzip mina-testnet-postake-medium-curves=0.2.6-5c08d6d --allow-downgrades

check version coda with commandcoda version
return Commit [DIRTY]5c08d6d51111d31269e77f3c62a544b3262ee4c8 on branch HEAD

Setup Keypair

1.2. - For Testworld, we are sending out pre-generated keypairs to every participant. Once you receive the link to claim your keypair, download it onto your computer.

mkdir ~/keys
wget -O ~/keys/new-keys.zip <keypair-download-url>

1.3 - Unzip recieved keys

apt install unzip
cd keys
unzip new-keys.zip

Example return

Archive: new-keys.zip
  inflating: extra_fish_account_9999
 extracting: extra_fish_account_9999.pub

1.4. - Rename them for our convenience:

mv extra_fish_account_9999 my-wallet
mv extra_fish_account_9999.pub my-wallet.pub

exit from directories cd or cd .

1.5. - Set access rights for our keys:

echo 'export KEYPATH=$HOME/keys/mina-wallet' >> $HOME/.bashrc
echo 'export MINA_PUBLIC_KEY=$(cat $HOME/keys/mina-wallet.pub)' >> $HOME/.bashrc
source ~/.bashrc

Peer list
