Stablecoins have become a cornerstone of the cryptocurrency ecosystem, bridging the volatile world of digital assets with the stability of traditional fiat currencies. Among the various models, one stands out for its decentralized, trustless, and transparent design: DAI, the stablecoin issued by MakerDAO. In this in-depth exploration, we dive into the insights of Pan Chao, MakerDAO’s former China lead and economic researcher, to understand why he champions digital asset-collateralized stablecoins over other models.
The Evolution of a Blockchain Economist
Pan Chao’s journey into blockchain began during his university years, where he studied monetary theory and was deeply influenced by Friedrich Hayek’s The Denationalisation of Money. This intellectual foundation, combined with technical skills in programming and economics, led him naturally to MakerDAO—a project that fuses economic theory with cutting-edge blockchain technology.
After working at Coursera as their first Chinese employee and pursuing graduate studies in economics in Europe, Pan joined MakerDAO, drawn by its mission to create a decentralized financial system. "It was the perfect intersection of my expertise in monetary economics and my passion for blockchain," he explains.

Three Models of Stablecoins: A Structural Breakdown
According to Pan Chao, stablecoins can be categorized into three fundamental models:
1. Fiat-Collateralized Stablecoins (e.g., USDT)
These are centralized tokens backed by reserves of fiat currency—typically the U.S. dollar—held in traditional bank accounts. Tether (USDT) is the most prominent example.
While effective as a bridge for traders to enter and exit crypto markets without relying on direct fiat on-ramps, this model faces critical challenges:
- Transparency issues: Audits are infrequent and often contested.
- Regulatory dependency: Their existence hinges on banking relationships and compliance frameworks.
- Centralization risk: Users must trust the issuer to hold adequate reserves.
As regulatory environments evolve and direct fiat-to-crypto gateways become more accessible, the necessity of such stablecoins may diminish.
2. Crypto-Collateralized Stablecoins (e.g., DAI)
This is where MakerDAO’s DAI shines. Unlike USDT, DAI is generated through over-collateralization of digital assets—like ETH—locked in smart contracts on the Ethereum blockchain.
Here’s how it works:
- A user deposits ETH into a Collateralized Debt Position (CDP).
- They can then generate DAI up to a certain loan-to-value ratio (e.g., $150 worth of ETH to borrow $100 in DAI).
- The DAI maintains its peg via market-driven arbitrage and automated mechanisms.
This model offers:
- Decentralization: No central authority controls issuance.
- Transparency: All collateral and debt positions are publicly verifiable.
- Resilience: Even during market crashes, built-in liquidation mechanisms protect solvency.
Pan emphasizes: “DAI isn’t just a stablecoin—it’s a decentralized credit system. It enables users to access liquidity without selling their long-term holdings.”

3. Algorithmic Stablecoins (The “Algorithmic Central Bank” Model)
This approach attempts to stabilize price through supply adjustments—minting or burning tokens based on demand—without relying on collateral.
Pan is highly critical of this model. He argues that it ignores fundamental economic realities:
- The assumption that velocity (V) in the equation MV = PY is constant is flawed.
- When confidence drops, there’s no incentive for users to buy "bonds" or "shares" to absorb excess supply.
- Without real collateral or credible backing, these systems often collapse under stress—just as seen in the 2022 TerraUSD crash.
“Calling it an ‘algorithmic central bank’ is misleading,” Pan says. “You don’t get to play central banker without having the balance sheet—or the credibility—to back it up.”
How DAI Survives Market Crashes
One of the biggest concerns about crypto-collateralized stablecoins is their performance during black swan events—such as a sudden 90% drop in ETH’s price.
MakerDAO addresses this through a multi-layered safety net:
- Overcollateralization: Positions require at least 150% collateralization, providing a buffer.
- Automated Liquidations: When collateral ratios fall below thresholds, anyone can liquidate the position and receive a small bonus—ensuring rapid deleveraging.
- MKR Token as a Backstop: In extreme cases where liabilities exceed assets, new MKR tokens are minted and sold to raise funds to cover the shortfall—acting like a decentralized deposit insurance mechanism.
- Global Settlement: As a last resort, users can redeem DAI for proportional collateral during system shutdowns.
“This isn’t just theory,” Pan notes. “These mechanisms have been stress-tested through multiple market downturns and proven resilient.”
The Future of Stablecoins: Two Coexisting Paradigms
Pan believes two stablecoin models will coexist for the foreseeable future:
| Model | Characteristics | Use Cases |
|---|---|---|
| Fiat-Collateralized | Centralized, regulated, high liquidity | Trading, remittances, regulated DeFi |
| Crypto-Collateralized | Decentralized, transparent, permissionless | Lending, borrowing, on-chain credit |
However, he sees long-term growth favoring the latter. “As blockchain infrastructure improves—with layer-2 scaling, cross-chain interoperability, and better risk management tools—crypto-collateralized stablecoins will unlock new financial primitives.”
Applications could extend far beyond trading:
- Supply chain finance: Tokenized invoices backed by on-chain collateral.
- Decentralized insurance: Risk pools funded by overcollateralized positions.
- On-chain mortgages: Long-term loans secured by digital assets.
Debunking Myths: GUSD and the Illusion of “Regulatory Advantage”
When Gemini Dollar (GUSD) launched under New York State regulatory oversight, some predicted it would overtake USDT. Pan disagrees.
“GUSD isn’t government-backed,” he clarifies. “It’s issued by a regulated trust company—not the U.S. Treasury. That’s a huge difference.”
Moreover:
- Regulatory compliance introduces friction: slower issuance and redemption.
- Limited scalability: Cannot rapidly expand supply during high demand, leading to premiums.
- No true decentralization: Still relies on centralized custody and governance.
While regulation adds legitimacy, it doesn’t solve the core issues of trust and accessibility that decentralized models aim to address.
FAQ: Your Questions About DAI and Stablecoins Answered
Q: Is DAI really stable? What happens if ETH crashes?
A: Yes, DAI has maintained its peg through multiple market crashes thanks to overcollateralization and liquidation mechanisms. Even if ETH drops sharply, automated processes protect the system’s solvency.
Q: Do I need to trust MakerDAO to use DAI?
A: No. DAI operates through open-source smart contracts. You can verify all collateral and transactions on-chain—no intermediaries required.
Q: Can anyone create a DAI-like stablecoin?
A: Technically yes, but replicating MakerDAO’s economic safeguards, community governance, and security audits is extremely difficult.
Q: What role does MKR play?
A: MKR is both a governance token and a risk-absorbing asset. Holders vote on system parameters and bear losses in case of insolvency.
Q: Why not just use USD on blockchain?
A: Traditional fiat-backed tokens lack decentralization and censorship resistance. DAI offers financial inclusion without relying on banks or governments.
Q: Is DAI used outside speculative trading?
A: Absolutely. It's widely used in DeFi protocols for lending, borrowing, yield farming, and even payroll in some Web3 organizations.

Final Thoughts: Building Financial Systems That Last
Pan Chao’s vision is clear: the future of money lies in systems that combine economic rigor with decentralized technology. While fiat-collateralized stablecoins serve a transitional role, the long-term value lies in open, transparent, and resilient architectures like DAI.
“Innovation isn’t about slapping AI or big data onto old ideas,” he warns. “It’s about understanding monetary principles—and building systems that work with human behavior, not against it.”
As blockchain matures, collateralized stablecoins are poised to become foundational infrastructure—not just for crypto traders, but for a new era of global, inclusive finance.
