代币化黄金：运作机制、优势及风险分析
代币化黄金将实物黄金映射到区块链，通常代表一盎司或特定重量的黄金，并允许用户进行碎片化投资。发行方将黄金存入托管仓库，利用智能合约铸造代币，并通过第三方审计或预言机证明储备（PoR）来维持锚定。这虽然结合了黄金的稳定性与加密市场的流动性，但引入了托管方信任风险、监管不确定性以及潜在的流动性折价。我们在投资此类 RWA

Tokenized gold converts physical gold into a digital token. Usually, one token equals one ounce of physical gold or a specific weight. It allows for fractional ownership in decimal units, enabling investment in gold with small amounts without buying expensive gold bars. It combines the asset stability of gold with the speed of the crypto market and the convenience of 24-hour trading.
Introduction
Gold has served as a store of wealth for thousands of years. It is considered a safe-haven asset, especially during economic instability. However, owning physical gold can be cumbersome. It is heavy, difficult to move, and requires a secure place for storage. Moreover, buying gold bars is too expensive for many people.
Tokenized gold attempts to solve these problems by putting gold on the blockchain. This is part of the Real World Asset (RWA) trend, creating a digital version of physical gold bars or coins. As more people seek the safety of gold without the storage hassle, this market is growing rapidly.
What is Tokenized Gold?
Tokenized gold is a digital token on the blockchain representing ownership of actual physical gold. These tokens usually function like stablecoins, but they are pegged to the price of gold rather than the US dollar.
Typically, one token holds a value equal to a specific weight of gold, such as a troy ounce (approx. 31.1g) or 1g. The actual gold is held in secure vaults by a custodian (a company responsible for safety). Since these tokens exist on blockchains like BSC or Ethereum, you can send them to friends, trade them like other cryptocurrencies, and use them in financial apps.
How It Works
The process of gold tokenization generally follows three main steps.
- Custody: The issuer purchases physical gold (bars or coins) and stores it in insured, secure vaults. This ensures the digital token is backed by real-world value.
- Digitization and Issuance: The issuer uses smart contracts to issue digital tokens on the blockchain. The number of tokens issued must match the amount of gold held in reserves (e.g., issuing 100 tokens for holding 100 ounces of gold).
- Audit and Proof: To maintain trust, reputable issuers use third-party audit firms to verify that the gold in the vaults matches the circulating token supply. Some projects use oracle networks like Chainlink to provide Proof of Reserves (PoR), ensuring on-chain transparency.
When a user wants to exit the investment, they can sell the token on an exchange or, in some cases, redeem it with the issuer for physical gold (subject to minimum quantity and fee conditions). To maintain the 1:1 peg, the corresponding digital token is burned (destroyed).
Advantages of Tokenized Gold
- Accessibility and Fractional Ownership: Physical gold bars can cost thousands of dollars. Tokenization allows ownership in decimal units, so anyone with a smartphone can invest in gold.
- 24/7 Liquidity and Efficiency: Traditional gold markets operate only during banking hours, and settlement can take days. In contrast, tokenized gold trades on crypto exchanges that run year-round, allowing you to buy and sell instantly at any time.
- Transparency and Security: Blockchain technology provides immutable ownership records. Combined with regular audits and proof of reserves, investors can verify the authenticity of their assets more easily than some traditional paper gold products.
- DeFi Utility: Unlike physical gold sitting idle in a vault, tokenized gold can be productive. You can use it as collateral for loans in DeFi protocols or add it to liquidity pools to earn interest, increasing asset utility.
Key Examples
- Tether Gold (XAUt): Issued by the company behind USDT. Each token tracks the price of one troy ounce of London Good Delivery gold. The gold is stored in Swiss vaults.
- Paxos Gold (PAXG): Issued by Paxos Trust Company and regulated by the New York State Department of Financial Services. Each token is backed by one ounce of gold stored in Brink’s vaults in New York.
Risks and Limitations
Tokenized gold is innovative, but you must be aware of the following risks.
- Custodial Risk: Unlike trustless Bitcoin, tokenized gold requires trust that the issuer actually holds the gold and will fulfill redemption obligations. If the issuer goes bankrupt or manages reserves poorly, the token value could drop.
- Regulatory Uncertainty: As with the broader crypto market, regulations regarding stablecoins and RWAs are still evolving. Legal changes could impact token issuance or trading.
- Market Liquidity: While growing, liquidity for tokenized gold on crypto exchanges is still lower compared to the massive global physical gold market.
- Fees: You should check for blockchain transaction fees (gas fees) and custody or management fees charged by the issuer.
Conclusion
Tokenized gold serves as a bridge between traditional finance and the digital economy. It modernizes gold, offering a solid option for investors who want to protect assets from inflation without the stress of storing physical bars. As Real World Asset (RWA) technology advances, we expect to see higher trading volumes, better transparency tools, and more people using gold-based tokens.
