Central Counterparty
A central counterparty is an entity that sits between the buyer and seller of a financial contract, acting as the buyer to every seller and the seller to every buyer. This structure reduces counterparty risk for individual participants because they no longer rely on the creditworthiness of the specific person on the other side of the trade, but rather on the clearing house.
In traditional finance, this is a highly regulated clearing house; in crypto, it is often the exchange itself. By guaranteeing the trade, the central counterparty simplifies the clearing and settlement process.
However, this creates a single point of failure where the entire system's stability depends on the clearing house's risk management. If the central counterparty fails, the entire market can collapse.
It is the core of modern derivatives market architecture.
