Tutorial: Merkle Trees and the IPFS DAG


These Lessons introduce the following concepts:

  • Cryptographic Hashes and Content Addressability
  • Authenticated Graphs
  • Turning Files into Trees
  • Turning any Data into Trees
  • Publishing hashes on the DHT
  • Getting data from the Peer to Peer Network



  1. Lesson: Turn a File into a Tree of Hashes
  2. Lesson: The Cryptographic Hash
  3. Lesson: Build a Tree of Data in IPFS Using Cryptographic Hashes to Link the Pieces (a Merkle DAG)
