Preface
Stablecoins dominate cryptocurrency discussions for good reason. Beyond speculation, they represent one of the few crypto products with a proven product-market fit (PMF). Analysts predict trillions in stablecoin adoption within traditional finance (TradFi) over the next five years—but not all that glitters is gold.
The Original Stablecoin Trilemma
Projects often use comparative charts to highlight their uniqueness, yet a critical trend goes underreported: the regression of decentralization. As markets mature, scalability demands clash with early crypto-anarchist ideals, necessitating a delicate balance.
The initial trilemma rested on three pillars:
- Price Stability: Maintaining a peg (e.g., to the USD).
- Decentralization: No single point of control, ensuring censorship resistance.
- Capital Efficiency: Minimal collateral requirements to sustain the peg.
Over time, scalability challenges forced adaptations. Notably, some projects replaced "decentralization" with "censorship-resistant"—a narrower concept that sidesteps full decentralization.
👉 Why decentralization matters in stablecoins
Centralization Creep: Causes and Consequences
Motivation: The March 2020 market crash exposed DAI’s vulnerability, pushing its reserves toward centralized assets like USDC. Algorithmic stablecoins (e.g., UST) and rebase models (e.g., Ampleforth) failed spectacularly. Regulatory pressures further stifled innovation, while institutional stablecoins gained traction.
Case Study: Liquity emerged as a decentralized outlier, using Ethereum collateral and immutable contracts. Yet, its scalability limitations (e.g., 90% LTV vs. competitors’ 100%) and niche Ethereum-centric community hindered mass adoption—despite $370M in TVL across forks.
Regulatory Headwinds
The Stablecoin Act in the U.S. prioritizes fiat-backed, regulated stablecoins, sidelining decentralized, crypto-collateralized, and algorithmic variants. This legal focus exacerbates centralization, leaving innovators in a gray area.
Value vs. Distribution: The New Battlefront
Stablecoins fall into three camps:
- Institutional Hybrids (e.g., BlackRock’s BUIDL): Target TradFi expansion.
- Web2.0 Entrants (e.g., PYUSD): Struggle with crypto-native scalability.
Yield-Focused Strategies:
- RWA-Backed (e.g., USDY): Leverage real-world assets.
- Delta-Neutral (e.g., USDe): Derivatives-based yields.
All share centralized governance, even when using Ethereum infrastructure.

Emerging Hope: Decentralized Alternatives
Projects like MegaETH and HyperEVM pioneer new approaches. For example:
- CapMoney: Plans gradual decentralization via Eigen Layer.
- Felix Protocol: A Liquity fork gaining traction as a chain-native stablecoin.
These models harness blockchain-centric distribution and the "novelty effect"—but face uphill battles against entrenched giants.
FAQ Section
Q1: Why is decentralization critical for stablecoins?
A1: It ensures censorship resistance and aligns with crypto’s trustless ethos—unlike centralized alternatives that mimic traditional finance.
Q2: Can algorithmic stablecoins recover after UST’s collapse?
A2: Possible, but they require robust mechanisms to avoid death spirals and regulatory acceptance.
Q3: How does the Stablecoin Act impact DeFi?
A3: It marginalizes decentralized options, pushing innovation offshore or into unregulated spaces.
Q4: What’s Liquity’s edge despite low adoption?
A4: Pure decentralization and Ethereum-backed collateral—but scalability remains its Achilles’ heel.
Conclusion
Centralization offers pragmatic benefits (control, scalability, compliance) but betrays cryptocurrency’s foundational principles. The original trilemma—price stability, decentralization, and capital efficiency—remains unmet. While new projects spark optimism, the industry must reconcile growth with its decentralized roots to fulfill stablecoins’ true potential.
