Staking

Definition ∞ Staking is a process within certain blockchain networks, particularly those utilizing Proof-of-Stake consensus mechanisms, where participants lock up their digital assets to support network operations and validate transactions. In return for this service, stakers receive rewards, typically in the form of additional cryptocurrency. It serves as a method for network security and a way for asset holders to generate yield.
Context ∞ News coverage on staking frequently discusses yield rates, the mechanics of delegated staking, and the implications of staking rewards on asset supply and market dynamics. Regulatory scrutiny regarding staking services, particularly concerning potential classification as securities, is also a growing area of discussion.
