You can confirm any given peer is holding a particular portion of a file (sometimes called the "confirmation of file attack") however you can't prove they published it. The peer "block chain" will only contain transfer metadata, not specifically which files are transfered. That information is only known by the peers involved in the exchange. And that's where the anonymity of the system is definitely inferior to FreeNet: peers involved in any given exchange know exactly what was transferred and to what IP address. I decided not to solve the anonymous transport problem because Tor, I2P etc are working quite diligently on that and it's a hard enough problem in and of itself. I think this has been a big stumbling block for FreeNet.
