go-ipfs development

This is a simple description of where the codebase stands.

There are multiple subpackages:

  • bitswap - the block exchange
  • blocks - handles dealing with individual blocks and sharding files
  • blockservice - handles getting and storing blocks
  • cmd/ipfs - cli ipfs tool - the main entrypoint atm
  • config - load/edit configuration
  • core - the core node, joins all the pieces
  • fuse/readonly - mount /ipfs as a readonly fuse fs
  • importer - import files into ipfs
  • merkledag - merkle dag data structure
  • path - path resolution over merkledag data structure
  • peer - identity + addresses of local and remote peers
  • routing - the routing system
  • routing/dht - the DHT default routing system implementation
  • swarm - connection multiplexing, many peers and many transports
  • util - various utilities

What's done:

  • merkle dag data structure
  • path resolution over merkle dag
  • local storage of blocks
  • basic file import/export (ipfs add, ipfs cat)
  • mounting /ipfs (try {cat, ls} /ipfs/<path>)
  • multiplexing connections (tcp atm)
  • peer addressing
  • dht - impl basic kademlia routing
  • bitswap - impl basic block exchange functionality
  • crypto - building trust between peers in the network
  • block splitting on import - Rabin fingerprints, etc

What's in progress:

  • ipns - impl /ipns obj publishing + path resolution
  • expose objects to the web at http://ipfs.io/<path>

What's next:

  • version control - commit like data structure
  • more...

Cool demos

A list of cool demos to work towards

  • boot a VM from an image in ipfs
  • boot a VM from a filesystem tree in ipfs
  • publish static websites directly from ipfs
  • expose objects to the web at http://ipfs.io/<path>
  • mounted auto-committing versioned personal dropbox
  • mounted encrypted personal/group dropbox
  • mounted {npm, apt, other pkg manager} registry
  • open a video on ipfs, stream it in
  • watch a video with a topology of 1 seed N leechers (N ~100)
  • more in section 3.8 in the paper
