While staking, liquidity mining, and yield farming all involve users being compensated for supporting something, they differ in their underlying nature. Specifically: - Staking traditionally referred to validating transactions in proof-of-stake networks to increase security, but the term is now more broadly used. - Liquidity mining incentivizes providing liquidity on decentralized exchanges to ensure trades can be properly executed. - Yield farming encompasses practices like lending and providing liquidity on DEXs in exchange for variable payments based on stake size. The key differences lie in the entities providing rewards and their motivations for doing so.
