# 權益證明（PoS）

> **最後更新：2026 年 1 月**

## 資本主義的重現

許多區塊鏈使用者發現[Proof of Work](/qu-kuai-lian-ru-he-da-cheng-gong-shi/consensus/pos-1.md)並不如想像中的完美，除了要求每個參與者擁有數台以上的GPU外，進行封箱運算的電力也相當可觀。於是提出一個貼近資本主義的共識：“有錢人說的算”。

權益證明(Proof of Stake或PoS)的Stake指的是你在整個區塊鏈網絡中有多少份額，也就是如果網絡崩潰的話你會受到的損害程度。基於一個直觀的假設：“你在網絡有越多錢，你越care網絡的品質與永久性”，也就是說擁有50%總資產的[鯨魚](/ru-quan-bi-bei-zhi-shi/undefined-5.md)，會比擁有0.01%的小蝦米更在意區塊鏈品質。就是說，所有的決定權應該都交由有錢人，他們對自己最好的決定，對區塊鏈網絡也是最好。

## 有錢人可以弄你

權益證明最大的問題在於：“有錢人可能有錢到不care”。比方說有錢人A的1%資金在區塊鏈K佔比80%，貧窮小戶B的100%資金在區塊鏈K佔比20%。這樣一來，A隨便亂來就可以把B搞掉，畢竟對A而言區塊鏈K只是小投資，對B而言這可是全部。
