Locking up cryptocurrency in a blockchain network to help validate transactions and earn rewards.
Staking is the process of locking cryptocurrency in a Proof of Stake blockchain to help secure the network, validate transactions, and earn rewards. When you stake tokens, you're essentially putting up collateral that vouches for the integrity of the blockchain — if the validator you stake with acts maliciously, a portion of the stake can be destroyed (slashed). In return, stakers earn new tokens (similar to interest) typically ranging from 3-15% APY depending on the network. Solo staking (running your own validator) provides the most decentralization benefit but requires technical knowledge and minimum amounts (32 ETH for Ethereum). Liquid staking protocols (Lido, Rocket Pool) let users stake any amount and receive a liquid derivative token (stETH, rETH) that represents their stake plus accruing rewards — usable across DeFi while still earning staking yield. This innovation unlocked hundreds of billions in previously illiquid staked capital.
Staking is the process of locking cryptocurrency to support a blockchain network's operations in exchange for rewards — the PoS equivalent of mining. Stakers pledge their tokens as collateral, earning yield for honestly validating transactions. The staking landscape has evolved dramatically: from requiring technical expertise and running validator hardware, to simple one-click delegation through wallets, to liquid staking protocols that maintain token liquidity while earning staking rewards. Total crypto staked value exceeds $300 billion, with Ethereum alone accounting for over $100 billion. Staking yields vary widely: Ethereum earns 3-5%, Solana 6-8%, Cosmos 15-20%. It's crucial to distinguish between real yield (from protocol revenue and network utility) and inflationary yield (from new token issuance that dilutes non-stakers). High nominal APYs on smaller chains often reflect high inflation rather than genuine returns.
Over 33 million ETH (worth $100B+) is staked on Ethereum — about 28% of total supply — with Lido alone managing over $15B in staked ETH, making it the largest DeFi protocol by TVL.
No. Risks include: slashing (losing staked tokens for validator misbehavior), smart contract risk (for liquid staking), lock-up periods (tokens unavailable during unstaking), and inflation risk (staking yield may not exceed token supply dilution). Additionally, staked tokens remain exposed to the asset's price volatility — earning 10% APY doesn't help if the token price drops 50%.
