ما هو الفرق بين التوقيع المساحي والتكديس السائل؟

Could you elaborate on the distinction between staking and liquid staking? I'm particularly interested in understanding how these two concepts operate differently within the cryptocurrency ecosystem. Could you explain the advantages and disadvantages of each approach? Additionally, could you provide some examples of popular cryptocurrencies that support staking and liquid staking, respectively? It would be helpful to have a clearer picture of how these mechanisms are applied in practice.
