Starting a network

Initially, every user is given a persistent Coreum network with a 7 day trial. This network can be kept by subscribing to the basic plan. To learn how to use the network, visit Interacting with a network.
To create an additional Coreum network click on "Create a network" and follow the on-screen process to configure the network.
Networks are given a random network name which can be changed to any name with a maximum of 25 characters. Next, you need to create a node configuration to add nodes to the network. A node configuration is a template for nodes which then allows to add an arbitrary number of nodes with custom configurations to the network.
Please see below for the standard node configuration. A configuration name is also automatically generated but can be arbitrarily chosen. Currently, the platform only supports the eu-west-1 region and the standard docker image. Nodes can be configured with up to 8 CPUs, 32 GB of memory, and 200 GB of storage.
Each node automatically creates an account with a starting balance. If the node is a validator, the staking amount needs to be less than the account balance. A network needs at least one validator in order to function properly.
Additionally, the platform supports multiple network parameters that can be configured. Please see the table below for further explanations.
Chain ID
The chain ID of the network; Can either be coreum-devnet-1 or coreum-testnet-1; This determines the address prefix and coin denomination.
Block size (MB)
The size of each block that is produced; A high block size will increase tps but also increase memory usage.
Faucet amount
The total treasury of the faucet; This should be set to a large number to avoid running out of token supply.
Transfer amount
The amount of tokens that is transferred on each faucet transfer.
Maximum gas
The maximum gas that can be consumed within a block.
Minimum gas price
The lowest fee per unit of computational work (gas) that a user must pay to have their transaction included in a block by the network's validators.
Transactions spammer
The transaction can simulate transactions in the network. The number specifies the number of transactions per second sent in the network.
Maximum validator
The number of maximum validators allowed in the network. 64 corresponds to the current mainnet.
Once you click Done, the network will be created. It will show once it's running or you can click on the network to see the progress in real-time. The logs give insight into the network creation process and show any errors in case something goes wrong.
Once you initiate a network, it will incur costs in your account. Please check the Pricing page for more information.
