Apa itu Staking yield, liquid staking token, restaking?

The staking yield is the return earned by locking a proof-of-stake chain’s token with a validator (Chapter 14): new issuance and a share of fees, less penalties. A liquid staking token is a transferable token that represents staked tokens and their accruing rewards, issued by a protocol that stakes deposits on its users’ behalf. Restaking is committing already-staked tokens, or liquid staking tokens, as security for further services, for additional rewards and additional risk of their being destroyed for misbehaviour.
