Hardware requirements​

  • Memory: 8 GB RAM
  • CPU: Quad-Core
  • Disk: 1 TB SSD Storage
  • Bandwidth: 1 Gbps for Download/1 Gbps for Upload

Setting up full storage node​

Server preparing​

sudo apt -q update
sudo apt -qy install curl git jq lz4 build-essential
sudo apt -qy upgrade

full-1

Install Go​

ver="1.20.2" 
cd $HOME 
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" 
sudo rm -rf /usr/local/go 
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" 
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile

Check Go version​

go version

You should see output like:

Download the binary file​

cd $HOME 
rm -rf celestia-node 
git clone https://github.com/celestiaorg/celestia-node.git 
cd celestia-node/ 
git checkout tags/v0.8.0 
make build 
make install 
make cel-key

Create key for node​

note

Change f5nodes to your moniker

  • Create a new key
./cel-key add f5nodes --keyring-backend test --node.type full --p2p.network blockspacerace

full-6

  • Restore an existing key using a mnemonic (optional)
./cel-key add f5nodes --keyring-backend test --node.type full --p2p.network blockspacerace --recover

Then we can go to #faucet channel for “Blockspace Race” and request test tokens in format: 

$request <celestia1ux3y......>

Initialize Full Node​

note

Change f5nodes to your moniker 

celestia full init \
  --keyring.accname f5nodes \
  --p2p.network blockspacerace

Useful commands​

Check wallet​

cd celestia-node
./cel-key list --node.type full --keyring-backend test --p2p.network blockspacerace

Check wallet balance​

curl -X GET http://127.0.0.1:26659/balance

Get full node ID​

AUTH_TOKEN=$(celestia full auth admin --p2p.network blockspacerace)
curl -X POST \
     -H "Authorization: Bearer $AUTH_TOKEN" \
     -H 'Content-Type: application/json' \
     -d '{"jsonrpc":"2.0","id":0,"method":"p2p.Info","params":[]}' \
     http://localhost:26658

Check logs​
