IPFS 0.8 Is Released

The Interplanetary File System (IPFS) is a system for storing and transfering verifiable, content-addressed data in a peer-to-peer network. You can imagine a combination of a large git tree and huge BitTorrent swarm to get an idea of how it works. That's not what it is, but is very roughly how it works. One difference between git and IPFS is that the data stored on IPFS is not necessarily persistent. It is possible to make data persist on your own IPFS node by "pinning" it. go-ipfs, the GO implementation of the file system server part of IPFS, supports remote pinning as of version 0.8.0. You can now ask remote services to pin your data for you using a authenticated API but you can't expect random strangers to do that for no reason. There is simply no incentive to pin some random strangers data since IPFS does not have any crypto-currency, or any other payment system, built into it. The new remote pinning feature is therefore mostly useful for remote IPFS servers under your control or the control of someone you've paid or made some deal with.
