Plain-English definition
Liquid staking gives you a token representing your staked position, which you can then trade or use elsewhere while the underlying stays staked and earning. You keep the yield and the liquidity.
It has become one of the largest categories in DeFi, which also means a lot of the system's depth depends on these representations holding their value.
Why it matters
Liquid Staking matters because crypto markets can look precise while still being shallow, crowded, or poorly sourced. A useful read is not just the number. It is the number, the size behind it, the context around it, and the part it cannot explain.
Simple example
A simple Liquid Staking example is a reader comparing two venues with the same headline price but different depth. The deeper venue can absorb more capital before the trade, peg, or yield reading starts to move against the user.
How Bathymark uses this term
Bathymark uses Liquid Staking to translate open market data into live liquidity readings. When the term touches a live page, the reading links back to the relevant chain, protocol, stablecoin, DEX, perps, or Signal so the source remains checkable.
Common mistake
The common mistake is treating Liquid Staking as a complete signal by itself. Bathymark treats it as one instrument: useful when read beside liquidity, source, size, and what the number cannot prove.
