Sui Kiosk: Digital Self-Service Machines for Encryption Assets

Sui Kiosk is a native feature on the Sui blockchain designed to help creators and IP holders realize their business models on the blockchain. It provides creators with flexible options that allow them to set transaction conditions in various trading scenarios.

Definition and Functions of Sui Kiosk

Sui Kiosk can be seen as a digital version of a self-service machine in the real world. Unlike physical self-service machines that sell physical goods, Sui Kiosk offers digital assets and NFT collectibles. By creating and placing assets in the Sui Kiosk, creators can define the policies and rules that control the future ownership, sales, and management of the assets.

This model, controlled by creators rather than the market, avoids issues seen in other blockchains and markets, such as the cancellation of mandatory royalty enforcement. Sui Kiosk utilizes Sui's shared object model to become a trusted source of existence, where anyone can view the assets listed for sale and interact with them.

The basic components of Sui Kiosk include:

1. Kiosk + KioskOwnerCap: Allows owners to store and list assets for sale
2. TransferPolicy + TransferPolicyCap: defines the conditions for asset trading or sale.
3. Rules: The specific terms within the TransferPolicy specify how to trade the objects.

Sui Kiosk also supports extensions to implement complex scenarios such as auctions and lotteries.

Kiosk Application in SuiFrens

As part of the initiative by early supporters, Mysten Labs issued 380,000 SuiFrens Bull Shark NFTs to recognized addresses. These NFTs are stored in a Kiosk that controls the sale method, specifies royalties, and can only be transferred under specific conditions.

Two key rules have been implemented in the SuiFrens Bull Shark Kiosk:

1. Copyright rules: stipulate that a certain amount should be paid to the creator when reselling.
2. Locking Rules: Prevent assets from being traded outside of the Kiosk to avoid circumventing royalty rules.

These rules demonstrate a simple example of mandatory royalty enforcement. Many creators on Sui also use other tools like Origin Byte Kiosk.

User Guide for Kiosk

Creators can create a TransferPolicy for assets, specifying different transaction requirements. Taking SuiFrens Bull Shark as an example, its TransferPolicy defines the royalty rules and locking rules.

The royalty rules specify the amount of royalties to be paid during secondary market sales. The locking rules ensure that assets can only be traded through NFT markets that support Kiosk, enforcing the royalty rules.

In the future, new features such as soul binding Kiosk and bottom price rules will be developed to provide more protection for creators.

Future Development of Kiosk

SuiFrens is just a simple application of Kiosk in terms of royalties. In the future, more complex business models will emerge on Sui, such as customized trading scenarios and business model transformations. The native functions of Kiosk will support fair trading in a decentralized environment while protecting creators' rights and maintaining transparency.
