Fungibility

Definition ∞ Fungibility describes an asset’s property where each unit is interchangeable with another identical unit. A fungible asset can be replaced by any other unit of the same asset without a loss of value or utility, similar to how one dollar bill is equivalent to any other dollar bill. Cryptocurrencies like Bitcoin and Ethereum are generally considered fungible, meaning each coin holds the same value and properties as another of its kind. This characteristic is fundamental for their use as a medium of exchange and store of value in digital economies.
Context ∞ Fungibility is a critical concept in discussions about the nature of cryptocurrencies versus non-fungible tokens (NFTs), often appearing in market analysis and digital asset news. Debates sometimes arise regarding the “tainting” of certain fungible coins due to their involvement in illicit activities, which can affect their perceived interchangeability. Maintaining fungibility is important for the seamless operation of decentralized financial systems and the liquidity of digital assets.
