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"
[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source $HOME/.bash_profile
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin
go version

3. Set Variables​

MONIKER="Moniker_name"
echo "export MONIKER=$MONIKER" >> $HOME/.bash_profile
echo "export PRYSM_CHAIN_ID="prysm-devnet-1"" >> $HOME/.bash_profile
source $HOME/.bash_profile

4. Download Binary​

cd $HOME
rm -rf prysm
git clone https://github.com/kleomedes/prysm prysm
cd prysm
git checkout v0.1.0-devnet
make install
prysmd version

5. Configure and Initialize Application​

prysmd init $MONIKER --chain-id $PRYSM_CHAIN_ID
sed -i -e "s|^node *=.*|node = \"tcp://localhost:26657\"|" $HOME/.prysm/config/client.toml
sed -i -e "s|^keyring-backend *=.*|keyring-backend = \"os\"|" $HOME/.prysm/config/client.toml
sed -i -e "s|^chain-id *=.*|chain-id = \"prysm-devnet-1\"|" $HOME/.prysm/config/client.toml

6. Download Genesis File and Addrbook​

wget -O $HOME/.prysm/config/genesis.json https://spidernode.net/prysm/genesis.json
wget -O $HOME/.prysm/config/addrbook.json https://spidernode.net/prysm/addrbook.json

7. Configure Seeds and Peers​

SEEDS="[email protected]:29656,1b5b6a532e24c91d1bc4491a6b989581f5314ea5@prysm-testnet-seed.itrocket.net:25656"
PEERS="[email protected]:29656,ff15df83487e4aa8d2819452063f336269958d09@prysm-testnet-peer.itrocket.net:25657"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.prysm/config/config.toml

8. Configure Pruning & Indexer​

sed -i -e "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.prysm/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.prysm/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"50\"/" $HOME/.prysm/config/app.toml

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.00001uprysm\"/" $HOME/.prysm/config/app.toml
sed -i 's|^indexer *=.*|indexer = "null"|' $HOME/.prysm/config/config.toml
sed -i 's|^prometheus *=.*|prometheus = true|' $HOME/.prysm/config/config.toml

9. Create Service File​

sudo tee /etc/systemd/system/prysmd.service > /dev/null <<EOF
[Unit]
Description=Prysm-testnet
After=network-online.target

[Service]
User=$USER
ExecStart=$(which prysmd) start --home $HOME/.prysm
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

10. Enable Service and Start Node​

sudo systemctl daemon-reload
sudo systemctl enable prysmd
sudo systemctl start prysmd && sudo journalctl -fu prysmd -o cat

11. Check Status​

prysmd status | jq
prysmd status | jq '{ latest_block_height: .sync_info.latest_block_height, catching_up: .sync_info.catching_up }'

12. Monitor Block Sync​

while true; do
  local_height=$(prysmd status | jq -r '.sync_info.latest_block_height');
  network_height=$(curl -s https://rpc-prysm.coha05.com/status | jq -r '.result.sync_info.latest_block_height')
  blocks_left=$((network_height - local_height));

  echo -e "\033[1;38mYour node height:\033[0m \033[1;34m$local_height\033[0m | \033[1;35mNetwork height:\033[0m \033[1;36m$network_height\033[0m | \033[1;29mBlocks left:\033[0m \033[1;31m$blocks_left\033[0m";
  sleep 5;
done

13. Create Validator​

  • Add new wallet:
prysmd keys add "wallet_name"
  • Check balance:
prysmd q bank balances $(prysmd keys show "wallet_name" -a)
  • Create validator.json file:
cd $HOME
echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(prysmd comet show-validator | grep -Po '\"key\":\s*\"\K[^\"]*')\"},
    \"amount\": \"1000000uprysm\",
    \"moniker\": \"Moniker_name\",
    \"identity\": \"\",
    \"website\": \"\",
    \"security\": \"\",
    \"details\": \"\",
    \"commission-rate\": \"0.1\",
    \"commission-max-rate\": \"0.2\",
    \"commission-max-change-rate\": \"0.01\",
    \"min-self-delegation\": \"1\"}" > validator.json
  • Create validator:
prysmd tx staking create-validator validator.json \
  --from "wallet_name" \
  --chain-id prysm-devnet-1 \
  --gas auto --gas-adjustment 1.5 \
  -y

Backup Validator Key​

  • File location: ~/.prysm/config/priv_validator_key.json
  • Copy this file to your local machine and store it securely as it is crucial for your validator.
