Staking

Staking is the process of locking up cryptocurrency to participate in the operation and security of a proof-of-stake (PoS) blockchain network. By staking their tokens, holders become validators (or delegate to validators) who are responsible for verifying transactions and creating new blocks. In return, stakers earn rewards — typically paid in the same cryptocurrency — similar to earning interest on a savings account, though with notably different risk characteristics.

Staking mechanisms vary across networks. Direct staking (running your own validator node) requires significant technical knowledge and often a large minimum stake (32 ETH for Ethereum, worth over $80,000). Delegated staking allows token holders to delegate their stake to a professional validator while retaining ownership. Liquid staking protocols like Lido issue a derivative token (stETH) representing your staked position, allowing you to use your staked assets in DeFi while still earning staking rewards — solving the liquidity problem of traditional staking.

Staking yields vary by network and typically range from 3-15% annually. Factors affecting rewards include the total amount staked on the network, the network's inflation schedule, transaction fee distribution, and validator performance. Risks include slashing penalties (losing staked tokens if the validator misbehaves), lock-up periods during which tokens cannot be withdrawn, smart contract risk with liquid staking, and the opportunity cost of not having immediate access to staked assets during market downturns.
