Hardware requirements

CPU: 4 Cores
RAM: 16 GB
SSD: 300 GB
Ubuntu 20.04 or 22.04

STEP-1, Let's update our server:

sudo apt-get update && sudo apt-get upgrade -y

STEP-2, Install Nethermind clients (enter the commands one by one):

IMPORTANT! Do not forget to forward ports: 30303 and 9000 on your router or digital hosting! Otherwise, your nodes will not be discoverable and will not sync!

Generate JWT secret file by executing the following command:

openssl rand -hex 32 | tr -d "\n" > "/tmp/jwtsecret"

sudo apt-get install curl screen zip wget

screen -S nethermind

sudo apt-get install libsnappy-dev

wget https://github.com/NethermindEth/nethermind/releases/download/1.20.4/nethermind-1.20.4-d06ec791-linux-x64.zip

unzip nethermind-1.20.4-d06ec791-linux-x64.zip

rm -rf nethermind-1.20.4-d06ec791-linux-x64.zip

We start the command in the stage at once in the screen, instead of "PORT1" type the port that you want to be ws, such as 8599 ... Wait a little, then exit the screen with CTRL+A and D.. To enter the screen again "screen -r nethermind" :

./Nethermind.Runner \
--config gnosis \
--Init.WebSocketsEnabled true \
--JsonRpc.Enabled true \
--JsonRpc.EnabledModules "eth,net,web3,subscribe" \
--JsonRpc.WebSocketsPort <PORT1> \
--JsonRpc.Host 0.0.0.0 \
--JsonRpc.JwtSecretFile /tmp/jwtsecret \
--baseDbPath ~/nethermindDb \
--JsonRpc.Timeout 120000 \
--Sync.FastSync true

STEP-3, Install Lighthouse (enter the commands one by one):

screen -S lighthouse

curl -LO https://github.com/sigp/lighthouse/releases/download/v4.5.0/lighthouse-v4.5.0-x86_64-unknown-linux-gnu.tar.gz

tar -xvf lighthouse-v4.5.0-x86_64-unknown-linux-gnu.tar.gz

sudo cp lighthouse /usr/bin

rm -rf lighthouse lighthouse-v4.5.0-x86_64-unknown-linux-gnu.tar.gz

We start the command in the stage at once in the screen "PORT2, PORT3, PORT4" instead of typing the desired port, such as 6699 7799 8899 ... Wait a little, then exit the screen with CTRL+A and D.. The time to sync "screen -r lighthouse" to enter the screen again can exceed 24 hours!!!

lighthouse beacon_node \
--network gnosis \
--debug-level info \
--datadir ~/gnosis-lh1 \
--execution-endpoints http://127.0.0.1:8551 \
--jwt-secrets /tmp/jwtsecret \
--enr-udp-port <PORT2> } \
--enr-tcp-port <PORT3>  \
--discovery-port <PORT4>  \
--checkpoint-sync-url https://checkpoint.gnosis.gateway.fm \
--disable-deposit-contract-sync

You will see something like this:

Some errors may pop out - ignore them. At the same time, your execution client will catch up:

STEP-4: Expose JSON RPC Port

To utilize the RPC endpoint (provided by your execution client) on an outside machine, enable port forwarding for port 8546 and use the following address: ws://ip.of.your.server:8546, replacing the phrase with the actual IP address of the PC your Nethermind client runs on.

If the PowerAgent is to be run on the same machine, it is not necessary to enable port forwarding.
