==2000 SANs per validator (20 000 SANs max cup for send)==

Running SANR Network node in signer mode

Minimum requirements

Running SANR Network node in readonly mode

1. Go to project

cd /opt/sanchain/readonly

1.2 Update latest changes

git pull

1.3 Update configuration and settings edit

nano .env

EXTERNAL_IP=Server external address

NUM_VALIDATORS=1 (put here validators amount what you want to run - maximum 10 validators per node)

REWARD_RECIPIENT_ADDRESS=Reward recipient address (you should have access to this account)

2. Run ./scripts/create_mnemonic.sh

Follow these steps:

Choose language: English

Specify the number of validators: 1 (put here validators amount from step 1.3)

Enter account address from .env (REWARD_RECIPIENT_ADDRESS) (you should have access to this account)

Confirm account address

Choose language: English

Enter a password for the validator keystore (record and store in a secure place)

Confirm the password

The generated mnemonic will be displayed (record and store in a secure place)

Enter the mnemonic again

After successful execution, a files/validator_keys directory will be created.

3. Validator wallet creation

3.1 Create a password for the validator wallet

echo "someStrongPassword" > files/validator.txt

(replace someStrongPassword to password which you want to use)

3.2 Execute the script ./scripts/create_validator_wallet.sh

Wallet password: Enter the password created in Step 3.1

Enter the password for your imported accounts: Enter the password for the validator keystore from Step 2

After successful execution, a files/wallet folder will be created.

4. Startup

4.1 Create Geth home directory

./scripts/gen_home_dir_geth.sh

4.2 Configure the Node Type

rm -rf docker-compose.yml

ln -s docker-compose-validator.yml docker-compose.yml

4.3 Launch the Project

docker compose up -d

5. Calculate and send required SANs amount to ETH Mainnet staking address: 0xbFE5D25956F6D7CF212a24B628c7871A34c4465f

The formula for calculation is your amount of validators * 2000 SAN

(max 20 000 SANs for stake, because max 10 validators per node)

6. Attach files/validator_keys/deposit_data.json to dashboard

Running SANR Network node in readonly mode

Minimum technical requirements

• CPU 8 CORE

• MEMORY 16 GB

• SSD(NVME) 300 GB

• Static IP 8 MBit/sec broadband

Recommended technical requirements

• CPU 16 CORE

• MEMORY 32 GB

• SSD(NVME) 300 GB

• Static IP 10 MBit/sec broadband

Software

• OS Ubuntu latest

• Docker

• Docker Compose

1. Environment setup

1.1 Create a directory and Navigate to it

mkdir -p /opt/sanchain/readonly

cd /opt/sanchain/readonly

1.2 Clone the Project

git clone https://github.com/santiment/sanr-pos-network.git .

1.3 Configuration and settings edit

mv env.example .env

nano .env

• EXTERNAL_IP=Server external address

1.4 Configure the Node Type

./scripts/gen_home_dir_geth.sh
ln -s docker-compose-readonly.yml docker-compose.yml

1.5 Launch the Project

docker compose up -d

Troubleshooting

1. Check if all processes are running correctly.

cd /opt/sanchain/readonly
docker compose ps

The command's result should have the following statuses:

• readonly_geth status: up

• readonly_beacon-chain status: up

• readonly_logrotate status: up

2. In the beacon-chain logs:

docker compose logs --tail 1000 -f beacon-chain

This command will display the last 1000 lines of the beacon-chain container log. You should see messages like this:

level=debug msg="Received block" blockSlot=34@4382 graffiti="" prefix=sync proposerIndex=55 sinceSlotStartTime=76.010571ms validationTime=4.057363ms

This indicates that the node is working.

level=info msg="Processing block batch of size 60 starting from  0x9389e285... 449921/486903 - estimated time remaining 16m58s"

This indicates that the node is syncing. Need wait and check again.

3. In the validator logs(Signer mode):

cd /opt/sanchain/readonly
docker compose logs --tail 1000 -f beacon-chain

This command will display the last 1000 lines of the validator container log. You should see messages like this:

level=info msg="Submitted new sync message" blockRoot=0xeae8befa51dd prefix=validator slot=501236 slotStartTime=2023-11-01 11:05:04 +0000 UTC timeSinceSlotStart=1.681908152s validatorIndex=71

This indicates that the validator work current.

Full restart node

cd /opt/sanchain/readonly
./scripts/stop_clear.sh
./scripts/gen_home_dir_geth.sh
docker compose up -d

Important. Follow the commands step by step. There should be no errors during execution

Monitoring

We collect statistics on active nodes (determining network lag, node configuration parameters and etc).

Make sure that your server and node has:

1. The ICMP protocol is open.

2. The following ports are open:

   • 13002/tcp, udp - p2p

   • 9102/tcp - stats beacon-chain

   • 33003/udp - geth

Important. Check the firewall settings on both the server and the datacenter(management panel).

You can use the following tools for monitoring:

1. ICMP checker: https://www.meter.net/tools/world-ping-test/

2. Check open ports: https://www.yougetsignal.com/tools/open-ports/

Please note: Do not change the ports, as it will make your node appear unavailable.
