A. Glossary of Terms
This glossary provides definitions for technical terms, financial concepts, and blockchain terminology used throughout this paper. Terms are organized thematically for easy reference.
Core Stablecoin Concepts
Stablecoin: A digital currency designed to maintain stable value relative to a reference asset, typically the US dollar
Peg: A fixed exchange rate between two currencies or assets; for stablecoins, typically maintaining 1:1 value with USD Example: 1 USDC should always equal $1.00
Collateral: Assets held in reserve to back the value of issued stablecoins; can include cash, government securities, or cryptocurrencies
Reserve: The total pool of assets held by a stablecoin issuer to support the circulating supply and maintain the peg
Mint/Burn: Creating new stablecoin tokens (minting) when dollars are deposited, or destroying them (burning) when redeemed
Market Cap: Total value of all stablecoins in circulation; calculated as number of tokens × price per token
Attestation: Third-party verification by accounting firms confirming reserve assets exist
Custodian: Regulated entity like BNY Mellon that holds and safeguards reserve assets
Float: The profit potential from investing reserve assets while stablecoins remain in circulation
Seigniorage: Revenue generated from the difference between the cost of creating money and its face value
Stability Mechanisms
Fiat-backed: Stablecoins backed 1:1 by traditional currency reserves held in bank accounts
Crypto-backed: Stablecoins collateralized by cryptocurrencies, typically over-collateralized for safety Example: MakerDAO requires $150 of ETH to borrow $100 of DAI
Algorithmic: Stablecoins that use smart contracts and economic incentives to maintain stability without full collateral backing
Hybrid: Stablecoins combining multiple stability mechanisms, such as partial reserves with algorithmic adjustments
Over-collateralization: Holding reserves worth more than issued stablecoins as a safety buffer
