Requirements

Linux Instance

OS - Ubuntu 18.04 or a higher version

Specifications

Specifications	Minimum	Recommended
CPU	4 Core	8 Core
RAM	16 GB	32 GB
Disk	SSD 1 TB	SSD 1 TB 8,000 IOPS 250 MB/s throughput Read latency < 1 ms
Network	> 5 MB/s	> 50 MB/s

Using a system with minimum specifications increases the risk of reaching full memory capacity, which may lead to slashing. Ensure you have enough memory and specifications to support the network data.

Allowed Inbound and Outbound

• Protocol - TCP and UDP

• Port - 30303

• Source IP - 0.0.0.0/0

Installation

Create a new directory for your validator node

mkdir -p kub-node && cd kub-node

Download the Genesis file and the configuration file using wget

wget https://raw.githubusercontent.com/kub-chain/bkc-node/main/mainnet/genesis.json
wget https://raw.githubusercontent.com/kub-chain/bkc-node/main/mainnet/config.toml

Download the latest release; the current version is v2.3.0

wget https://github.com/kub-chain/bkc/releases/download/v2.3.0-bkc/geth2.2.0.darwin-arm64.tar.gz

Verify that the downloaded version is compatible with your device. KUB supports Darwin ARM64, Linux x86-64, and Linux ARM64. Visit the latest release page to view the available versions under the assets section.

Extract the downloaded file

tar -xvf geth2.3.0.darwin-arm64.tar.gz

Set the password, replace YourPassword with your password

echo "YourPassword" > ./password.sec

Create a new validator account

./geth --datadir ./data account new --password ./password.sec

Your public address will be generated after creating the account. Please write it down, as you will need it in the later steps.

Initialize the Genesis file

./geth --datadir ./data init ./genesis.json

Run geth using the following command and replace 0xYourPublicAddress with your public address retrieved in the earlier steps

./geth --datadir ./data \
    --config ./config.toml --password ./password.sec \
    --syncmode snap \
    --mine \
    --unlock 0xYourPublicAddress --allow-insecure-unlock 

Please allow some time for your system to download and sync the network data.

Validator Staking

After successfully installing your node configuration on your system, please proceed to the next steps. Staking involves depositing the KUB Coin to activate the validator.

You can choose whether to be a validator of a Solo Node or a Pool Node, depending on how much KUB Coin you have staked. Your reward will be based on the amount of KUB Coin staked on the KUB network.
