Asset Tokenization: Transforming Real-World Assets into Digital Tokens

Asset tokenization is the process of converting real-world assets (such as real estate, artwork, commodities, stocks, or other valuable assets) into digital tokens on a blockchain network. This involves transforming ownership or rights of an asset into digital tokens, which are then recorded and managed on the blockchain.

High-Level Overview

The core concept revolves around fractionalizing high-value assets into smaller, more affordable units that represent ownership or a share of the asset. This strategy:

• Democratizes Investment: Enables broader participation by allowing investors to buy fractions rather than entire assets.
• Reduces Risk: Lets investors mitigate risk through fractional ownership.
• Enhances Liquidity: Facilitates easier trading of asset shares.

This model shares similarities with the ERC1155 multi-token standard but includes additional functionalities tailored for the Sui blockchain.

Key Components

1. Asset Creation
   Each asset is divided into a total supply, with fractions represented as:

   • Non-Fungible Tokens (NFTs): Unique tokens with distinct metadata.
   • Fungible Tokens (FTs): Interchangeable tokens with identical properties.

2. NFT vs. FT Differences

   • NFTs: Created with unique metadata; balance is fixed at 1.
   • FTs: No unique metadata; balance can exceed 1, allowing merging/splitting.
3. Burn Mechanism
   Assets can be designed as burnable, reducing circulating supply while maintaining total supply.

Move Package for Asset Tokenization

The asset_tokenization package leverages Sui's Move language to implement tokenization logic. Key modules include:

tokenized_asset Module

• Structures:

  struct TokenizedAsset {
    id: UID,
    balance: Balance,
    metadata: VecMap,
    image_url: Option<String>
  }

• Functions:

  • mint: Creates tokens (NFT/FT based on input).
  • split/join: Merges or divides FTs.
  • burn: Removes tokens from circulation.

proxy and unlock Modules

• Facilitate secure transfers and enforce policies (e.g., royalties, commissions).

Deployment Workflow

1. Initialize Sui Client:

   sui client init

2. Publish Packages:
   Deploy asset_tokenization and template packages:

   sui client publish --gas-budget 20000000

3. Configure Environment:
   Update .env with package IDs and network details.

WebAssembly (WASM) Integration

Enable dynamic editing of Move bytecode for web-based asset creation:

1. Retrieve Bytecode:
   Use xxd to extract module bytecode.
2. Edit Constants:
   Modify fields like TOTAL_SUPPLY or SYMBOL via TypeScript.
3. Publish Changes:
   Deploy updated modules to Sui.

TypeScript Interaction Examples

1. Mint Tokens:

   const { keys, values } = getVecMapValues(); // NFT or FT config
   await mintTokens(keys, values);

2. Lock in Kiosk:

   npm run call lock

3. Trade Assets:
   Use purchaseItem.ts to buy/sell fractionalized tokens.

FAQs

What is asset tokenization?

Asset tokenization converts physical or digital assets into blockchain-based tokens, enabling fractional ownership and trading.

How do NFTs and FTs differ in tokenization?

NFTs represent unique asset fractions (e.g., a specific painting), while FTs represent interchangeable shares (e.g., ounces of gold).

Can tokenized assets be burned?

Yes, if the asset is configured as burnable, reducing circulating supply while preserving total supply.
