All content published on MIX is registered with the Item Store contract, but the content itself is stored on IPFS.

IPFS has a feature called pinning. When an IPFS file is pinned it is synchronized to the device and will not be evicted by the garbage collection until it is unpinned. I have written a very simple daemon called MIX Pin that watches the MIX blockchain and pins every piece of content that is published.

This means that even when you go offline you can still browse all the content on MIX.

I have setup a server in Singapore that runs MIX Pin continuously. When you publish a piece of content this server will pin it immediately so your device does not need to be online for other users to see your content. This server will not be necessary once the MIX ecosystem is more mature.

Currently MIX Pin is very simple. Over time a number of improvements will be made:
