+# IPFS
+IPFS, or the InterPlanetary File System, is a peer-to-peer distributed file system designed to connect all computing devices with the same system of files. It works similiarly to [Torrents](../../tools/BitTorrent.md).
+
+## Key Concepts
+### 1. **Decentralization:**
+IPFS is designed to be a fully decentralized system where each node in the network stores a collection of hashed files. This eliminates the need for a central server, providing greater resilience and reducing single points of failure.
+### 2. **Content Addressing:**
+IPFS uses content addressing, where each file and all of the blocks within it are given a unique fingerprint called a cryptographic hash. This hash becomes the file's address on the network.
+### 3. **Distributed Hash Table (DHT):**
+IPFS utilizes DHT for efficient peer discovery and file lookup. It enables nodes to find the closest peers with a specific file.
+
+## Docker Compose
+```yml
+version: '3'
+
+services:
+  ipfs-node:
+    image: ipfs/go-ipfs
+    restart: always 
+    ports:
+      - "4001:4001"
+      - "127.0.0.1:8080:8080" 
+      - "127.0.0.1:5001:5001" 
+     volumes: 
+       - ./ipfs-data:/data/ipfs
+     command: ["--enable-pubsub-experiment", "--gateway", "all"]
+```
