       | I like the idea of a decentralized Internet Archive in theory,
       | but I'm very skeptical about the idea of decentralized (as
       | opposed to distributed) filesystems, and tying the whole system
       | to a cryptocurrency seems like this creates additional volatility
       | exactly in a situation where you want stability.
       | 
       | Buying hard drives and sticking them in data centers is a very
       | cost-effective, efficient way to store large amounts of data, and
       | with careful design (Internet Archive definitely qualifies) you
       | get amazing durability. The failure rate of hard disks is
       | relatively well-known or "mostly" bounded and predictable, so you
       | can fine-tune your data encoding to get a good tradeoff between
       | storage efficiency, CPU usage, network usage, and durability.
       | 
       | With a decentralized system, you're adding intermediaries with
       | some amount of additional risk that is difficult to model. The
       | idea is that these intermediaries have "leftover" storage which
       | is basically free, and Filecoin lets them sell it. However, the
       | risk that these intermediaries lose the data is difficult to
       | model and so you would likely choose a wider encoding
       | (https://en.wikipedia.org/wiki/Erasure_code) with poorer storage
       | efficiency and higher CPU usage.
       | 
       | Meanwhile, the cost of buying storage outright is already quite
       | low, and the cloud providers are already busy selling storage (or
       | using it themselves) in high-IO applications like active
       | databases, and this subsidizes raw storage (with low-I/O
       | requirements). Essentially, if someone in the cloud needs a 2TB
       | drive, the cloud provider can buy an 8TB drive instead, split it
       | in half, and sell it as "2TB + priority I/O" and "6TB + best-
       | effort I/O".
       | 
       | Finally, in order to be stable long-term, Filecoin needs to
       | provide enough income to miners so they can be profitable. I
       | don't see a good story for how this can happen. The most
       | profitable thing you can do per-byte is to sell "leftover"
       | storage on existing systems that are not full, but this doesn't
       | give you enough to cover overhead, so you would want to run a
       | large operation. Once you are running a large operation, your
       | costs would be similar to that of a cloud provider, but your
       | customers would be choosing wider encodings with lower storage
       | efficiency. If Filecoin were to turn into a common market for
       | larger storage operations, it would then make sense to vet those
       | operations and develop business relationships with them, because
       | by reducing risk you could increase storage efficiency and reduce
       | costs. There is a de facto way to do this already: several cloud
       | providers implement the S3 API, so you can shop around fairly
       | easily, as long as you are willing to transport the data.
       | 
       | Short story is that distributed storage is in a race to the
       | bottom with or without Filecoin, it's already "hyper-
       | competitive", and I'm unconvinced that Filecoin provides benefits
       | that outweight the drawbacks.

         | Neither Filecoin nor IPFS guarantee content is available

         | it around until you unpin it, if you download it you may share
         | it out for a period of time). So suppose someone _does_ upload
         | some illegal content, if no one pins it or downloads it and the
         | original node hosting it were to drop off (as may be reasonably
         | expected if law enforcement becomes involved depending on
         | _what_ the content is) then it will disappear from the network.
         | IPFS does not forcibly distribute the content across the
         | network, only when it 's accessed does it become distributed.
         | And even then it's only temporary unless it's pinned and the

         | Filecoin, being based on IPFS, will be similar but with the

       |  _" The primary demand for Filecoin is from people trying to mine

       | That being said, the tech is pretty cool. And the funding scheme
