Create a Blockchain
This page describes how to create a Blockchain.
Create an Ethereum compatible PoA (Proof of work) Blockchain network using Geth by specifying the cluster type, number of nodes, and initial address.
In order to create a Blockchain network, you need to purchase a license and your own Wallet address.
If you have not purchased a license, you will be asked to purchase a license during the network creation process. If you do not have a Wallet, please install Lunascape Wallet and obtain your own address before starting to create a network.
To create a new network, click the "Create" on the [Create New Blockchain Network] screen that appears after you log in. The [Create Blockchain Network] dialog box will then appear. (All information above the advanced settings is required. The explanation of each item is here.

When you have finished filling in the required fields, click on the "Create" at the bottom of the dialog.
