Mainchain

There are two permanently accessible public Lisk blockchain networks which are entirely independent of each other: the Lisk Mainnet and the Lisk Testnet.

In addition to the permanent networks, it is also possible to spin up a local network for development, known as the Lisk Devnet, or to connect to a public network such as the Lisk Betanet, which is accessible during beta releases for new Lisk Core versions. Lisk Core is the blockchain client that is required to be installed on a server in order to configure a node that can connect to the respective Lisk mainchain.

Table 1 provides a comparison between the Mainnet and the Testnet mainchain, and lists their specific properties and configurations:

Lisk Mainnet

The Mainnet is where the true Lisk economy exists.

Within this network, Lisk users can transfer LSK tokens from one account to another, register accounts as validators to generate new blocks, or register their sidechains to make them interoperable with any other registered sidechain.

Token

The native token for the Lisk Mainchain is LSK, pronounced as "Lisk".

Each LSK is further subdivided into 10⁸ Beddows.

1 LSK = 100000000 Beddows

Proof of Stake (Mainnet)

Configurations of the PoS module of Lisk Mainnet mainchain.

Lisk Testnet

The Testnet is an independent replica of the Lisk Mainnet, primarily designed to test upgrades before implementing them on the Lisk Mainnet.

This is where the new upcoming versions and fixes of the Lisk Core are tested, and, subsequently applied to the Lisk Mainnet.

For users, the Testnet provides the possibility to perform their own tests of their Lisk applications, or to test their validator node setup, without spending any real LSK, or risking punishment^[2] on the Mainnet.

Using Lisk Desktop for a Testnet account

To connect to the Testnet via Lisk Desktop, simply enable the "Network Switcher" in the settings and then go back to the login screen and switch the network to Testnet in the dropdown menu.

Faucet

Get free Testnet LSK from the Testnet faucet to start using the Testnet for your own purposes.

Testnet LSK serves as "play money"

Testnet LSK holds no intrinsic monetary value; they are purely intended for testing purposes within the Lisk Testnet, eliminating the necessity to spend "real" LSK tokens. Furthermore, Testnet LSK cannot be exchanged for Mainnet LSK or any other currency.

Proof of Stake (Testnet)

Registered modules

Lisk Betanet

The Lisk Betanet is a temporarily accessible public blockchain network, that is used to test new beta releases of Lisk Core, prior to testing them on the Testnet.

In contrast to the Lisk Testnet, the Lisk Betanet is exclusively accessible during the beta testing phases of Lisk Core, which typically occur in preparation for major updates to the blockchain protocol.

The Betanet holds significant appeal for validators and Lisk application developers, offering them the opportunity to explore new releases ahead of their deployment on the Testnet and the Mainnet. This allows them to gain insights into new features and stay updated with the latest advancements in the protocol.

Furthermore, it is the first publicly accessible network for new releases of Lisk Core, which is testing the new release in a broader scope. This helps to identify and fix remaining issues with the release, and therefore participation from the community is welcomed during this phase. Feel free to play around in the Betanet and report any feedback or issues you might encounter in the dedicated channels on Lisk.chat.

The most important properties of the Lisk Betanet are listed in the table below:

Lisk Alphanet

Generally, a Lisk Alphanet is only used for internal testing purposes and will only stay online temporarily to perform quality assurance of the new software release.

Lisk Devnet

The Devnet is a local development network which can be set up on a single node.

The purpose of the Devnet is to provide a user-friendly locally set up blockchain network for performing specific tests, granting the user complete control over the environment.

This can be beneficial when planning to operate the blockchain with different configurations and/or modules compared to the public mainchains, or to test specific functionalities that might be too intricate or complex to evaluate on one of our public networks, such as the Betanet (whenever operational/available) or the Testnet.

Especially, it is recommended to set up a Devnet to search for bugs which can be reported through the Lisk Bug Bounty Program.

The Table 6 below displays the main default configuration for the Lisk Devnet.

Please note that all configurations displayed in Table 6, Table 7 and Table 8 are just the default values of the Devnet, and can be updated by the developer to meet their specific needs.
