2. Tamper proof: all contents are verified by their checksums. If the data is tampered with or damaged, IPFs will detect the data

3. De rendancy: all objects with identical contents are stored only once

PFS does not require every node to store all the content. The owner of the node can choose the data he wants to maintain freely. Besides backing up his own data, he voluntarily provides services for other concerned content
