I wish this article mentioned something about BitSwap; before reading the IPFS paper, I was doubtful about anyone wanting to participate without incentives. Still, even after skimming the paper, it sounds like a lot really depends on how well BitSwap is implemented. At one point, the paper says this: > While the notion of a barter system implies a virtual currency could be created, this would require a global ledger to track ownership and transfer of the currency. This can be implemented as a BitSwap Strategy, and will be explored in a future paper. So it kind of sounds like they need something like bitcoin, but don't want it to be tightly coupled to bitcoin - which is probably smart. But without a single clear solution for a reliable BitSwap strategy (and I'm not sure how it could be reliable without a distributed global ledger of some kind), it's hard to see how/why the necessary resources will be contributed to the IPFS network.
