In the context of cryptocurrencies, pegging refers to the stabilization of a digital asset's value by linking it directly to another asset, such as a fiat currency like the US dollar or another digital currency. This is often achieved through mechanisms like collateralization or through algorithms that adjust supply based on demand. Pegged cryptocurrencies, such as stablecoins, are designed to minimize volatility and provide a reliable medium of exchange and store of value in the inherently fluctuating crypto market.
