Summary:
- Overview: This paper studies how different stablecoin designs transmit systemic risk in crypto markets. The authors analyze eight major stablecoins using daily data from 2021 to 2025 and apply a Quantile Vector Autoregression model to measure spillovers during normal and extreme market conditions. The results show that stablecoin design strongly determines systemic risk behavior. Fiat-backed stablecoins act as “stability anchors,” producing almost no net spillover across the system. In contrast, algorithmic and crypto-collateralized stablecoins amplify systemic risk during extreme market conditions. The study also finds that stress events can break the separation between traditional finance and crypto markets, creating direct volatility links between the U.S. Dollar Index and Bitcoin. The authors argue that stablecoin regulation should vary by design rather than applying a single framework.
- Stablecoin Design Determines Risk: Fiat-backed stablecoins such as USDT and USDC maintain near-zero net spillovers across market conditions. Their reserve backing allows them to absorb redemption shocks without transmitting volatility to other assets. Algorithmic and crypto-collateralized stablecoins lack this buffer and instead rely on market transactions, which increases spillover risk during stress periods.
- Tail Risk Spillovers Rise: Spillovers are much stronger during extreme market conditions than during normal periods. The study finds that tail-event spillovers can increase by roughly 15-50 percentage points compared with median market conditions. This shows that traditional average-based models underestimate systemic risk in stablecoin markets.
- Fiat-Crypto Barrier Breaks: Under normal conditions, fiat markets, stablecoins, and crypto assets behave as mostly separate systems. During extreme stress, this separation collapses and direct volatility channels appear between the U.S. Dollar Index and Bitcoin. Crypto-collateralized and algorithmic stablecoins often act as conduits that transmit risk between these market layers.
- Implications For Regulation: The findings suggest stablecoin regulation should depend on mechanism design. Fiat-backed stablecoins may require reserve and banking-style oversight, while algorithmic and crypto-collateralized coins need stronger risk buffers. The authors estimate that capital requirements for non-fiat designs should be roughly two to three times higher than levels suggested by median risk measures.

Summary:
- Overview: This paper analyzes a common stablecoin design called the price window model, where users can mint and redeem stablecoins at fixed prices set by the protocol. These mint and redeem prices create a floor and ceiling around the market price. The authors show that this design cannot guarantee both short-term and long-term stability unless the reserves backing the stablecoin are already stable assets. If the backing asset is volatile, arbitrage traders can repeatedly exploit price differences between minting and redeeming. Over time, this arbitrage can drain the system’s reserves. To prevent this, the price window must be widened with higher fees, but this also increases the stablecoin’s price volatility. The paper therefore shows a fundamental tradeoff between peg stability and long-term sustainability.
- Price Window Mechanism Explained: Price window systems maintain stability by setting fixed mint and redeem prices around $1. These prices create a rational trading band where the stablecoin’s market price should remain. Examples include tokenized stablecoins and some crypto-backed systems that treat all users identically.
- Arbitrage Drains Reserves: If the backing asset price moves significantly, a speculator can mint stablecoins when backing assets are cheap and redeem them when prices change. Each cycle extracts value from the protocol’s reserves. Over time, repeated arbitrage can fully deplete reserves if transaction fees are too small.
- Volatility Inheritance Problem: The paper proves that the stablecoin’s volatility is directly linked to the volatility of its backing asset. If the backing asset price fluctuates widely, the protocol must widen its mint-redeem window to avoid arbitrage losses. This causes the stablecoin itself to inherit similar volatility levels.
- Design Implications For Stablecoins: Price windows alone cannot guarantee both peg stability and long-term solvency. Stablecoin systems need secondary stabilization mechanisms, such as governance tokens, adaptive fees, or additional collateral layers. Without these mechanisms, volatile backing assets make price-window designs fundamentally fragile.

Summary:
- Overview: This article proposes a structured method for designing token economies. The authors argue that many blockchain projects fail due to poor alignment across incentives, governance, and tokenomics. Existing research often studies these areas separately, but practical guidance that integrates them is limited. To address this gap, the paper introduces the Token Economy Design Method (TEDM). TEDM is a stepwise design framework built using Design Science Research and refined through a real case called Currynomics, which manages an asset-backed stablecoin. The method aims to help designers make clear decisions, identify trade-offs, and reduce risk early in development.
- Three-Pillar Design Structure: The method integrates three core pillars: incentives, governance, and tokenomics. Incentives define which stakeholder behaviors should be rewarded and how. Governance determines who has decision rights and how voting works. Tokenomics sets rules for supply, issuance, distribution, and price management. The key contribution is not new theory, but structured sequencing that makes trade-offs explicit across these three dimensions.
- Incentive Alignment Logic: The framework begins by identifying stakeholders, system functions, and desired behaviors. It then selects monetary and non-monetary incentives that reinforce long-term ecosystem value rather than short-term speculation. The authors emphasize “token-network fit,” meaning incentives must support system utility. Poorly designed incentives can lead to instability, price collapse, or value extraction instead of value creation.
- Governance Trade-Off Mapping: TEDM guides projects to define governance areas, decentralization targets, and voting mechanisms. It compares voting models such as 1-token-1-vote, time-weighted voting, reputation-based voting, and quadratic voting. The framework highlights trade-offs between simplicity, inclusivity, security, and resistance to plutocracy. It also recommends hybrid on-chain and off-chain governance to balance transparency with flexibility.
- Supply, Distribution, Stability: On the tokenomics side, the method structures decisions around supply policy (capped vs uncapped), release timing (pre- or post-launch), distribution channels (private sale, public sale, airdrops), value capture, and price management tools. Mechanisms such as staking, vesting, buybacks, and burns are treated as stabilization tools rather than growth tactics. The Currynomics case illustrates how asset-backed issuance, capped governance tokens, and token locking can reduce volatility and align long-term incentives. The authors position TEDM as qualitative design guidance that can later be combined with simulation or quantitative modeling.

Summary:
- Overview: This paper studies how economic policies affect wealth distribution in the Bitcoin token economy. Wealth distribution is measured by how Bitcoin supply is held across different address groups. The study separates exogenous policies (outside the system, like interest rates) from endogenous policies (inside the system, mainly Bitcoin Improvement Proposals, or BIPs). The authors first remove the influence of external macroeconomic factors from the wealth distribution data. They then test whether BIPs cause changes in the distribution of wealth using causality analysis. The results suggest that protocol policy changes do influence how Bitcoin wealth moves between address groups. The paper also proposes a taxonomy for economic policies in token economies.
- Exogenous Factors Filtering: The authors test many macroeconomic variables to see which ones affect Bitcoin wealth distribution. After statistical filtering, only two variables remain significant: the U.S. Federal Funds Rate and U.S. M2 money supply. These influence the smallest and mid-size address buckets. Removing these effects creates a “cleaned” dataset that isolates internal protocol policy impacts.
- Protocol Policy Effects: Bitcoin Improvement Proposals (BIPs) are treated as endogenous economic policies. Granger-causality tests show that sets of BIPs correlate with shifts in Bitcoin wealth distribution. Large policy events (for example SegWit or Taproot related changes) tend to affect smaller holders more strongly. Smaller or routine policy updates influence larger holders more often.
- Information Asymmetry Pattern: The study suggests that wealthy participants respond earlier to policy changes. They likely monitor the ecosystem closely and can act quickly. Smaller holders react mainly to large or widely publicized policy events. This creates an information asymmetry where wealthier actors move funds before others respond.
- Token Economy Policy Taxonomy: The paper proposes a policy framework for token economies similar to traditional macroeconomic policy. Policies are grouped into fiscal-like, monetary-like, and token-specific categories. Examples include supply limits, mining rewards, transaction rules, and wallet design policies. This taxonomy aims to help researchers analyze how protocol design choices influence economic outcomes in decentralized systems.

Summary:
- Overview: This thesis studies how blockchain technology changes incentive mechanisms in social media platforms. Traditional social media platforms capture most economic value while creators receive limited rewards. Blockchain-enabled social media (BSM) attempts to fix this through token economies, smart contracts, and decentralized governance. The research compares four platforms: PIXIE, GARI Network, Cheelee, and Odysee. The study examines how incentive mechanisms influence user engagement and the quantity and quality of user-generated content (UGC). Results show that token rewards, NFTs, and governance participation increase activity but also introduce challenges such as scalability and incentive sustainability. The study proposes design principles for building balanced and user-centric incentive systems in blockchain social platforms.
- Blockchain Social Media Model: Blockchain-enabled social media platforms redesign value distribution using tokens and decentralized infrastructure. Users can receive rewards directly through smart contracts rather than through centralized platform decisions. This system aims to create fairer value sharing and stronger community ownership of platforms.
- Multi-Level Incentive Systems: The study identifies several incentive layers used in BSM platforms. These include token rewards for activity, NFT-based incentives, staking rewards, and governance participation through tokens. Multi-level incentives help balance short-term engagement with long-term user commitment to the platform ecosystem.
- Impact on User-Generated Content: Blockchain incentives can increase both the quantity and quality of user content. Token rewards motivate creators to produce more content and interact with communities. However, poorly designed reward systems may lead to spam or low-quality content if users focus only on earning tokens.
- Design Challenges for Platforms: Despite their potential, BSM platforms face key limitations. These include technical complexity, scalability problems, and difficulty balancing short-term rewards with long-term ecosystem sustainability. Effective incentive systems must combine token economics, governance mechanisms, and technological infrastructure to maintain healthy platform growth.
