Installing Go

ver="1.20.3"
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

Celestia Light Node Installation

cd $HOME 
rm -rf celestia-node 
git clone https://github.com/celestiaorg/celestia-node.git 
cd celestia-node/ 
git checkout tags/v0.9.5
make build 
make install 
make cel-key
  • celestia version we should get the following output..
Semantic version: tags/v0.9.5

Init Process

  • Entering the command will create a new wallet named my_celes_key. Remember to save the address and mnemonics of this wallet!
celestia light init --p2p.network blockspacerace
  • When the above command is entered, it should give a result like the following.

NOTE: The core ip, rpc port, grpc port in the ExecStart command are taken from the endpoints provided in the Celestia documentation (https://docs.celestia.org/nodes/blockspace-race/#rpc-endpoints) and there are alternatives. If you want, you can change here and use different endpoints.

Start Standard

  • Enter the following code while on the Tmux screen.
celestia light start --core.ip https://rpc-blockspacerace.pops.one --core.rpc.port 26657 --core.grpc.port 9090 --keyring.accname my_celes_key --metrics.tls=false --metrics --metrics.endpoint otel.celestia.tools:4318 --gateway --gateway.addr localhost --gateway.port 26659 --p2p.network blockspacerace

Learning Node ID

AUTH_TOKEN=$(celestia light 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
  • When this code is entered, you will get a result like below ID="12D....." is your Node ID, you can find Uptime and other details by searching this on https://tiascan.com/light-nodes. 11111

NOTE: /root/.celestia-light-blockspacerace-0 under the keys folder must be backed up.
