What Lido Is
Lido is a liquid staking protocol. Staking helps secure Ethereum and earns rewards, but staked ETH is normally locked and running a validator takes technical work and a large minimum. Lido pools deposits from users around the world, and third-party node operators handle the technical setup of running validators on their behalf. Users can stake any amount rather than the 32 ETH a solo validator needs.
Where It Came From
Lido is an Ethereum-based protocol that launched in 2020, built to give stakers the ability to keep using ETH that would otherwise be locked while it helps secure the network. CoinDesk has described it as the provider that did more than any other to expand access to staking.
stETH and wstETH
When you stake ETH, you receive a derivative token called staked ether, or stETH, that represents your position and accrues staking rewards. Because it is a token, you can hold, trade or use it elsewhere in DeFi while it keeps earning. Lido's site also lists wstETH, a wrapped, non-rebasing version of stETH, and says stETH is available across multiple blockchain networks.
Governance and the LDO Token
Lido is governed by a decentralized autonomous organization (DAO) of LDO token holders, so core decisions about how the protocol evolves are made by community votes rather than by a company. Its size has also drawn criticism: Lido has at times held a very large share of all staked ETH, which critics argue concentrates too much influence in one protocol.
What to Weigh Before Using It
Liquid staking adds layers of risk on top of ordinary staking. Smart contract bugs, validator penalties known as slashing, and the possibility that stETH trades below the value of the ETH behind it during market stress can all cost you money. Staking concentration is also a network-level concern, not just a personal one. Start small, read the project's current documentation for the exact product you plan to use, and only commit money you can afford to lose. This summary is educational and not financial advice.
