基于文件的证明

简介

Proof of space 有 3 种小的分类，或者说另外的叫法，意思应该差不多：

• Proof of storage
• Proof of capacity
• Proof of space-time

Reference:

• Exploring Proof of Space with Hard-to-Pebble Graphs

这个是 IPFS 对 Proof of Storage 的解释：Proof-of-Storage

三种类别之间还是有区别的：Proof of Capacity Vs SpaceTime Vs Space Vs Storage – The Difference

Proof of Replication

Proof of data possession

PoDP 不是一种共识算法，它是指证明 server 端储存了数据，并且 client 可以验证。
