Node installation
git clone https://github.com/JackalLabs/canine-chain && cd canine-chain
git checkout v4.2.1
make install
canined version --long | grep -e version -e commit
# version: 4.2.1
# commit: 61000aff7787585bfb771d1d38057a3a2a702272
We initialize the node to create the necessary configuration files
canined init UTSA_guide --chain-id jackal-1
Download Genesis
wget -O $HOME/.canine/config/genesis.json "https://cdn.discordapp.com/attachments/1002389406650466405/1034968352591986859/updated_genesis2.json"
# check the genesis
sha256sum ~/.canine/config/genesis.json
# b6a0e67fbdf21b929d9080ac546db080790bc18c4931bea60fec8fb18559ad39
At this stage, we can download the address book
wget -O $HOME/.canine/config/addrbook.json "https://share.utsa.tech/jackal/addrbook.json"
Set up node configuration
