# IPFS (InterPlanetary File System)
###### tags: `區塊鏈` `技術`

**IPFS:** A peer-to-peer hypermedia protocol
designed to preserve and grow humanity's knowledge
by making the web upgradeable, resilient, and more open.

## 技術 (IPFS $\cong$ BitTorrent + Git + DHT + SFS):
1. Distributed Hash Tables (分散式哈希 使用1執行2 )
2. Content Based Addressing (內容尋址)
3. Git Version Control Systems (Git 版本控制)
4. Object Merkle DAG (莫克爾對象關聯)
5. Peer-to-Peer (點對點)
6. IPNS (全球化命名空間)

若所有存儲資源的用戶都下線了怎麼辦 -> Filecoin(跟IPFS是同一個開發團隊，搭建在IPFS上的區塊鏈應用)
