Hardware Requirements

Network Endpoints

---

Step 1 — System Verification

After SSH-ing into your server, verify the system meets requirements:

lsb_release -a          # Should be Ubuntu 22.04 or higher
uname -r                # Kernel version
lscpu | grep -E "Model name|CPU\(s\)|Thread|Socket|Core"
free -h                 # Minimum 8 GB RAM
df -h                   # Minimum 200 GB free disk

---

Step 2 — System Update and Dependencies

sudo apt update && sudo apt upgrade -y
sudo apt install -y curl git wget htop tmux build-essential jq make lz4 gcc unzip

---

Step 3 — Install Go

cd $HOME
VER="1.23.0"
wget "https://golang.org/dl/go$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"

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

Verify the installation:

go version

Expected output: go version go1.23.0 linux/amd64

---

Step 4 — Build Binary from Source

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

Set up Cosmovisor directory structure:

mkdir -p $HOME/.prysm/cosmovisor/genesis/bin
cp $HOME/go/bin/prysmd $HOME/.prysm/cosmovisor/genesis/bin/

sudo ln -sfn $HOME/.prysm/cosmovisor/genesis $HOME/.prysm/cosmovisor/current
sudo ln -sfn $HOME/.prysm/cosmovisor/current/bin/prysmd /usr/local/bin/prysmd

Verify:

prysmd version

Expected output: v0.1.0-devnet

---

Step 5 — Install Cosmovisor

go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]

Verify:

cosmovisor version

---

Step 6 — Create Systemd Service

Set your moniker and port prefix:

MONIKER="YOUR_MONIKER"
PORT="25"   # Default Prysm port prefix. Change to avoid conflicts if needed.

Create the service file:

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

[Service]
User=$USER
ExecStart=$(which cosmovisor) run start
Restart=on-failure
RestartSec=10
LimitNOFILE=65535
Environment="DAEMON_HOME=$HOME/.prysm"
Environment="DAEMON_NAME=prysmd"
Environment="UNSAFE_SKIP_BACKUP=true"
Environment="LD_LIBRARY_PATH=$HOME/.prysm/lib"
Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:$HOME/.prysm/cosmovisor/current/bin"

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable prysmd

---

Step 7 — Initialize the Node

prysmd config set client chain-id prysm-devnet-1
prysmd config set client keyring-backend test
prysmd config set client node tcp://localhost:${PORT}657
prysmd init $MONIKER --chain-id prysm-devnet-1

Set environment variables permanently:

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

---

Step 8 — Download Genesis and Addrbook

curl -Ls https://raw.githubusercontent.com/hazennetworksolutions/prysm/refs/heads/main/genesis.json \
  > $HOME/.prysm/config/genesis.json

wget -O $HOME/.prysm/config/addrbook.json \
  https://raw.githubusercontent.com/hazennetworksolutions/prysm/refs/heads/main/addrbook.json

Verify genesis:

sha256sum $HOME/.prysm/config/genesis.json

---

Step 9 — Configure Ports and Pruning

Custom Ports

sed -i.bak -e "s%:1317%:${PRYSM_PORT}317%g;
s%:8080%:${PRYSM_PORT}080%g;
s%:9090%:${PRYSM_PORT}090%g;
s%:9091%:${PRYSM_PORT}091%g;
s%:8545%:${PRYSM_PORT}545%g;
s%:8546%:${PRYSM_PORT}546%g;
s%:6065%:${PRYSM_PORT}065%g" $HOME/.prysm/config/app.toml

sed -i.bak -e "s%:26658%:${PRYSM_PORT}658%g;
s%:26657%:${PRYSM_PORT}657%g;
s%:6060%:${PRYSM_PORT}060%g;
s%:26656%:${PRYSM_PORT}656%g;
s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${PRYSM_PORT}656\"%;
s%:26660%:${PRYSM_PORT}660%g" $HOME/.prysm/config/config.toml

Gas Prices

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.00001uprysm\"/" \
  $HOME/.prysm/config/app.toml

Pruning

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 = \"19\"/" $HOME/.prysm/config/app.toml

Enable Prometheus (optional)

sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.prysm/config/config.toml

Disable Indexer (saves disk space)

sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.prysm/config/config.toml

---

Step 10 — Configure Seeds and Peers

SEEDS="1b5b6a532e24c91d1bc4491a6b989581f5314ea5@prysm-testnet-seed.itrocket.net:25656"
PEERS="[email protected]:61256,ff15df83487e4aa8d2819452063f336269958d09@prysm-testnet-rpc.itrocket.net:25656,01e40fe961c9522936a8bb7ede533198614abf9f@prysm-testnet-rpc.stakerhouse.com:14256,[email protected]:15656,[email protected]:26916"

sed -i -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*seeds *=.*/seeds = \"$SEEDS\"/}" \
       -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*persistent_peers *=.*/persistent_peers = \"$PEERS\"/}" \
       $HOME/.prysm/config/config.toml

---

Step 11 — Start the Node

sudo systemctl start prysmd
sudo journalctl -u prysmd -f --no-pager -o cat

Verify the service is running:

sudo systemctl status prysmd --no-pager

The service should show active (running).

Check sync status:

prysmd status 2>&1 | jq .SyncInfo

Wait until catching_up is false before proceeding to validator registration.

---

Step 12 — Create a Wallet

prysmd keys add wallet --keyring-backend test

⚠️ CRITICAL: Save your mnemonic phrase in a secure location. Without it, you cannot recover your wallet.

To recover an existing wallet:

prysmd keys add wallet --recover --keyring-backend test

Check your balance:

prysmd query bank balances $(prysmd keys show wallet -a --keyring-backend test)

---

Step 13 — Register as a Validator

The node must be fully synced before creating a validator.

Get your pubkey:

prysmd comet show-validator

Create validator JSON:

cat > $HOME/validator.json << EOF
{
  "pubkey": $(prysmd comet show-validator),
  "amount": "1000000uprysm",
  "moniker": "YOUR_MONIKER",
  "identity": "",
  "website": "",
  "security": "",
  "details": "",
  "commission-rate": "0.05",
  "commission-max-rate": "0.20",
  "commission-max-change-rate": "0.01",
  "min-self-delegation": "1"
}
EOF

Submit the transaction:

prysmd tx staking create-validator $HOME/validator.json \
  --from wallet \
  --chain-id prysm-devnet-1 \
  --keyring-backend test \
  --gas auto \
  --gas-adjustment 1.4 \
  --fees 500uprysm \
  -y

Verify your validator:

prysmd query staking validator \
  $(prysmd keys show wallet --bech val -a --keyring-backend test)

---

Monitoring the Node

Watch live block commits:

sudo journalctl -u prysmd -f --no-pager | grep "committed block"

Full logs:

sudo journalctl -u prysmd -f --no-pager

Sync status:

prysmd status 2>&1 | jq .SyncInfo

Service management:

# Restart service
sudo systemctl restart prysmd

# Stop service
sudo systemctl stop prysmd

# Check status
sudo systemctl status prysmd

---
