IPFS

• It's a file system with content based addressing.
  • Files are automatically deduplicated.
  • It chunks, hashes and organizes blobs in a smart way.
• Once something is added, it can't be changed anymore.
• IPFS supports versioning using commits.
• Keeping files available is a challenge. If the nodes storing a file go down, it'll disappear from the network. Filecoin can help with this adding incentives to the equation.
• IPFS makes some nice properties the default. E.g: content addressing.

IPLD

• Data model for IPFS
• Everything is a node. Nodes have types.
• The data structure is a Merkle Tree.
• Makes easy to have interoperability of data. Useful for distributed databases.
  • Bridges content addressing and distributed systems.

LibP2P

• Modular peer to peer networking layer.
• Multiple users across the decentralized ecosystem.
• Many implementations of each module.
