Staking is a mechanism used in proof-of-stake blockchain networks like Ethereum to secure the network by locking up cryptocurrency tokens as collateral. Liquid staking enhances traditional staking by allowing staked assets to be used as collateral in decentralized finance (DeFi) protocols, providing liquidity and additional earning opportunities. Liquid staking providers manage user deposits, stake tokens on behalf of users, and issue new tokens that represent claims on the staked assets, which can be traded or used in DeFi. These tokens introduce liquidity but also come with risks such as slashing, smart contract vulnerabilities, and market volatility. Prominent liquid staking protocols include Lido and Rocket Pool, which offer decentralized services, while centralized exchanges also provide liquid staking but differ in custodial control.
