How is this different from Siacoin?

FileCoin is using proof of storage of client data for blockchain ledger security. That's a very tricky thing to get right (I didn't think it was possible.) Search the white paper for "Sybil attack, outsourcing attacks, generation attacks", and see section 7.4 of the SiaCoin whitepaper for contrast: https://www.sia.tech/whitepaper.pdf

I still go back to this paper for questions about decentralized storage: http://blog.dshr.org/2017/07/is-decentralized-storage-sustai...

I think this argument fails even by its own standards. It applies equally well to Bitcoin mining, and while there is clearly some centralization there, it is still quite decentralized. At least, decentralized 'enough'. Secondly, storage is fundamentally different than other commodities. The decentralized storage market is more like AirBnB, where you're consuming the excess capacity of capital. Most people have tons of storage already that they're not using. Extracting rents from that space is found money, and therefore they have inherently lower costs than anyone supplying storage in a commercial way.

I'm still confused why I would want my storage to be decentralized. No I don't want my files spread on thousands or millions of computers no matter how encrypted etc.

This is the reason I can't take Silicon Valley too seriously. It isn't the magic algorithm, it is that no sane person would want Pied Piper's storage because it does just what you said in the context of the show.

What do you think Apple or Google does with your files after they are uploaded? Do you think they aren't encrypted and spread out over several machines?

Earlier quoted context omitted.

Actually there were experiments in the original Bitcoin paper. And it would've probably passed a workshop-related setting for academia. More than the academic presentation though, I'm just baffled by the lack of science that these projects with huge followings have.

Please be honest. When the original Bitcoin or Ethereum whitepapers came out, wouldn't your original comment, of these wp not passing any science/academia setting, still ring true then? Also, even if they don't pass an academia setting, what is your point? So many papers actually pass academia setting but does it do anything worthwhile? Filecoin is a project in existence for the past 3yrs working on top of IPFS, a po…

Care to elaborate on the "intuitive sense" part?

There is another macro-economic issue here:

With a decentralized trustless system you have to assume a higher failure rate for nodes than with a central trust based system.

If you assume a higher failure rate you have to replicate data more extensively to achieve reliability.

If you have to replicate data more extensively then decentralized will always be more expensive than centralized.

Coming from academia, these sort of papers would not pass any sort of double-bind peer review process. Where's the actual science? Where are the experiments? It seems to be just a document describing the protocol of Filecoin, which is fine. The problem is that all these "whitepapers" coming from these cryptocurrency communities seem to be promoted as scientific papers, but in reality do not stand a chance in any scie…

Also coming from academia, experimentation is not necessary for publication - both reviews and observational studies exist and are published in peer reviewed journals quite often.

In engineering (although I worked in neuroscience, I worked with many academic engineers and read way too many of their papers), whitepapers and concept papers are also often published - there's nothing to indicate here that this was a reviewed journal article. It's just a formatted PDF.

Filecoin and its underlying protocol IPFS assemble the world’s knowledge and data into one big content-addressed graph (Merkle DAG), and attempt to make it accessible to any device, anywhere. This is great because it allows for all kinds of use cases apart from just securely storing and sharing files. It’s much more than an app: it’s an underlying protocol, rather than Dropbox on a blockchain.

> FileCoin is using proof of storage

Yeah, Proof of Replication and Proof of Spacetime, to be precise.
