The IPFS ecosystem consists of several key components working together:
Core Components:
- IPFS Node: Software that implements the IPFS protocol and connects to the network
- DHT (Distributed Hash Table): Helps nodes find which peers have specific content
- Bitswap: Protocol for exchanging blocks of data between peers
- Merkle DAG: Data structure that organizes content into a directed acyclic graph
Supporting Infrastructure:
- IPFS Gateway: HTTP interface that allows traditional browsers to access IPFS content
- Pinning Services: Services that ensure content remains available on the network
- IPNS (InterPlanetary Name System): Provides mutable naming for immutable content
- Filecoin: Incentive layer providing persistent storage guarantees
Developer Tools:
- js-ipfs: JavaScript implementation of IPFS
- go-ipfs: Go implementation (most common)
- IPFS Cluster: Orchestrates pinning across multiple IPFS nodes
