The Best of Both Worlds: Understanding Liquid Staking
How stETH and Liquid Staking Tokens (LSTs) unlocked billions in 'trapped' capital.
Staking ETH to secure the network is great, but it has a major downside: your ETH is "locked" in a smart contract. You can't use it to buy an NFT or swap it for a different token. You are forced to choose between Security Yield and Liquidity.
Liquid Staking is the innovation that lets you have both.
The "Receipt" Token
When you deposit ETH into a Liquid Staking protocol like Lido or Rocket Pool, you receive a Liquid Staking Token (LST) in return, such as stETH or rETH.
This token is a "Receipt." It represents:
- Your original 1 ETH deposit.
- All the rewards that ETH has earned from staking.
The Magic of stETH
Because stETH is a standard token, it is "Liquid." You can take your stETH and:
- Use it as collateral to borrow money on Aave.
- Provide it as liquidity on Uniswap.
- Sell it instantly if you need cash, without waiting for the "Unstaking Period" of the Ethereum network.
The Decentralization Trade-off
Liquid Staking has been a massive success, with billions of dollars flowing into protocols like Lido. However, this has led to a "Centralization Concern." If one protocol controls 30% or more of all staked ETH, they gain too much power over the network.
The industry is now focused on Distributed Validator Technology (DVT) to ensure that "Liquid Staking" remains as decentralized as the "Raw Staking" it replaced.
