BaaS stands for “Blockchain as a Service” and refers to SaaS (Software as a Service) that enables users to use the infrastructure and technology of the blockchain in the form of a cloud-based service. Luniverse provides BaaS2.0, the next generation BaaS that offers various blockchain environments and services, such as Chain, Token, DApp, and User Management, required for the planning, development, and operation of DApps as a cloud-based service, which is different from BaaS1.0 that only provided a simple private chain infrastructure. Using Luniverse, DApp developers are now able to develop and operate DApps more easily and safely and also provide DApp services in a user-friendly environment for more users by offering end users a UX similar to the typical web/app environment.

Luniverse plans offer Chain Service, Token Service, DApp Service, and User Management Service. The same services are provided in all plans, but the chain specifications vary depending on the plan. We recommend choosing plans that consider the characteristics of the services as explained below.

  • Dev Plan
    Suitable for building a development environment for blockchain DApps, B2B services with lower traffic, or early-stage services.
  • Service Plan
    Suitable for building and operating a general blockchain DApp service.
  • Premium Plan
    Suitable for building and operating a blockchain DApp service with higher traffic and increased activity such as games. The plan selected for the chain can be conveniently upgraded as necessary. (The chain upgrade feature will be supported soon.)

There is no limit to the number of Side Tokens and DApps you can create. Simply create and use as many of them as you want on the Side Chain.

There is no limit to how many Side Chains you can create. Simply create as many chains as you need and you will be charged for the number of the created chains based on the plans and usage time. For example, if you’re using two chains via Dev Plan and one chain via Service Plan, the amount you will be charged is [the usage time on Dev Plan 1 * 2,200 Korea won + the usage time on Dev Plan 2 * 2,200 Korean won + the usage time on Service Plan 1 * 4,400 Korean won].

You can use up to 3 REOAs and 10 IP Whitelists per DApp.

Only one MT can be linked and used on each Side Chain. In addition, only one Side Chain can be linked and used with each MT.

A Side Chain consists of two Validator Nodes and one Monitoring Node. You can create and use as many nodes as you want for the purpose of maintaining governance, enhancing stability, etc., and more features such as governance of the Side Chain will be additionally developed and introduced in order. (The feature to create nodes will be updated soon.)

Luniverse supports a delegation contract to help various participants in the Side Chain manage their balance more conveniently for all gases they need to pay for by using the Main Chain. The Organization Owner may recharge all gases required for the operation of the Side Chain by recharging LUK in the Gas Delegation Contract of the Side Chain. Fees for the gases used by the members of the organization will be paid through the delegation contract. The Organization Owner may recharge all gases required for the operation of the Side Chain by recharging LUK in the Gas Delegation Contract.

Currently, up to Solidity v5.0 is supported in the Luniverse Side Chain. Solidity v5.1 or later versions are temporarily unavailable. Please deploy a smart contract created in Solidity v5.0 or earlier versions.
