> Cryptocurency integration and identity within IPFS could have been done without a new coin I don't think thats a fair claim to make. There are many attacks on 'pay for distributed storage' that Filecoin addresses. Take a look at [the paper](https://filecoin.io/filecoin.pdf https://filecoin.io/filecoin.pdf), in particular section 3.1 where we discuss sybil attacks, Outsourcing attacks, and generation attacks. We cover a lot of cases, and build in incentives to continually increase the amount of available storage and push down the price-per-byte. If we thought it was possible to properly incentivize data storage on ipfs without building a blockchain, we would have done so.
