conda-ipfs

What can IPFS do for conda(-forge) now?

• provide decentralized distribution of conda packages and metadata

How would this work?

• on a periodic basis (say, hourly) conda-forge could

What could do more?

• if conda packages were exploded at rest, similar to how they are stored in the pkgs directory...
  • they would be automatically deduplicated at the block level, such that incremental updates to a channel would be

  description: |
    IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas
    from previous systems such as Git, BitTorrent, Kademlia, SFS, and the Web.
    It is like a single BitTorrent swarm, exchanging git objects. IPFS provides
    an interface as simple as the HTTP web, but with permanence built-in. You
    can also mount the world at /ipfs.
