If I'm following correctly, I believe this is basically what Sia does, although not optimized to be used directly as a media server (or maybe it could?).

It's worth checking out Sia, which doesn't seem to get much attention: https://sia.tech/
It works, they have an active development team, and the network keeps growing: https://siahub.info/map

How is this different from Siacoin http://sia.tech/
Great idea anyhow and backed by Protocol Labs.
myautsai · 2017-07-08
Ethereum is an awesome idea, but before any practical Ether application booms, it's more like a bubble.
If you're interested in why there's also a token named "Ethereum Classic(ETC)", you can search "DAO" on Google to explore more about why the first largest Ethereum application DAO was failed and why this leads to the hard fork(ETH => ETC, ETH) of Ethereum.
As far as decentralized storage is concerned, there's production-already a blockchain-based product named Sia (http://sia.tech/ ), but Swarm (which is a similar thing based on Ethereum) is still in very early stage.
Taek · 2017-01-31
Full disclosure, I am the founder of Sia, which of course is my favorite and I do believe is far ahead of all the other platforms at this time. https://sia.tech
There is also Storj, MaidSafe, Filecoin, Swarm, and sort-of-but-not-quite IPFS.
Storj and Sia are the front runners for private data like family photos, computer backups, etc. I don't really consider Storj to be decentralized here though.
Swarm I know less about, but I believe their focus is more on file sharing. IPFS is closer to a replacement for http and BitTorrent (both), great for high-demand files or files that are being explicitly hosted on a web server but not so much private data. I think they plan to upgrade this with Filecoin.
MaidSafe is 10 years old and still in alpha. They have huge ambitions but I think too huge, they don't seem capable of publishing things.
Ajedi32 · 2022-10-24
The problem with decentralized systems that don't include a currency component is that there's no extrinsic incentive to contribute anything to the network, only to consume.
BitTorrent suffers from this problem; they even have a term for it: leeching. It's managed to survive despite this purely off of the generosity and goodwill of a community of dedicated users, but if BitTorrent were to ever have its eternal September moment I suspect the problem would quickly be felt rather acutely.
With other systems like decentralized cloud storage[1] or decentralized DNS[2] where (unlike with BitTorrent) there are no inherent practical limits on how many resources a single user can consume, the consequences of not including a currency component would be even more severe.
As for the "no recourse" problem, that's inherent to the very idea of self-sovereignty. Yes it's a weakness with decentralized systems, but it's also their greatest strength.

IPFS only does addressability, it doesn't provide storage. You could use a decentralized storage network like Arweave, Filecoin, or Sia.

Sia is a distributed cloud storage platform. It's an open marketplace that allows anyone to rent out their storage capacity, enforced by smart contracts. Storing data on Sia is cheaper than the traditional cloud, as well as being more secure (encrypted, no vendor lock-in, no single point of failure) and more performant (download from 30+ storage hosts in parallel, like a torrent).
The network has been running smoothly and quietly for around 6 years now, with steadily increasing usage. We're good at making stuff that works. We're not so good at hyping up our product and gaining developer mindshare. That's why we're hiring a Developer Evangelist. Come help us make Sia the leading platform in cloud storage!
Oh yeah, we're also hiring a frontend developer to make nice websites and UIs.

What you are describing is sorta already a thing, take a look at sia[0], which is a coin? used to purchase long-term data storage. You can't really scan the chain as far as I understand it but why not host the entire index on sia as well?

Decentralized and private cloud data storage: https://sia.tech
The benefit from using blockchain is that your data will be safely replicated and accessible from the cloud, and at the same time you are the sole owner of the data. Only your private key can access the data.
In this case, blockchain also facilitates a decentralized marketplace for sellers and buyers of data storage.
rwbaskette · 2020-03-07
Where are these datacenters? I live in Ohio in the area of two of the points on the home page at https://sia.tech/ One appears to be a private residence or a farm. The other dot is literally on a golf course fairway, is a private residence, or a power substation.

Also take a look at Skynet, a file sharing protocol built on top of Sia: https://siasky.net/
zherbert · 2020-02-18
Skynet is built on top of the Sia decentralized cloud storage platform (https://sia.tech). Sia uses a blockchain to facilitate cryptocurrency transactions and store file contracts (which are like cryptographic SLAs between users), and is very similar to Bitcoin in architecture.
Anyone can operate a Skynet Webportal (the server), and Webportals can choose how they'd like to monetize – for example, they can run ads.
You can also run your own Skynet Portal by downloading Sia v1.4.3, released today. It costs about $10/mo to run a Portal because you have to form file contracts with a few hundred storage providers on the network. But then you do not have to go through a Webportal middleman.
Disclaimer: I work on the Sia/Skynet team.

Sia is an interesting decentralized storage network: https://sia.tech/
Although there's still some scaling issues to sort out:

tetek · 2018-04-05
it puts incentives in the wrong place. I recommend reading this: https://blog.sia.tech/the-ico-paradox-and-how-to-fix-it-3bfc61bc6eb8
turblety · 2018-03-20
Sia [1] could be even cheaper, coming out at $1.10 for a TB [2]. Although this price might not be forever, and I'm still not sure about the reliability.
In theory it should be more reliable, as it's decentralised and your data gets split among multiple servers around the world. The question remains what if the Sia network itself stops being profitable and people all exit at the same time. Although the same could be said for Amazon?
Sia will actually soon be adding a backend to Minio too [3].
The only thing that has stopped me using Sia is you have to have the blockchain running on the machine.

Sia might be a good option - https://blog.sia.tech/

I have a strong suspicion that some of these exist as fronts to move flight capital out of China, Russia, and other places that hemorrhage dodgy money.
There almost seems to be an inverse relationship between reality and funds raised. Here's one of the very few real ones:
http://sia.tech
They got nowhere near the funding, and most of it was conventional:
http://sia.tech/funding2016/
It's one of the few coin-backed distributed things that seems like it might be useful to the point that I may actually try it, and I've heard it actually does work.
Guess that's passe in these quarters.
shelune · 2017-08-27
This, along with Siacoin (http://sia.tech/), will likely be the future of decentralised cloud storage.
They have active developments and have (somewhat) clear roadmap. I'm a bit concerned about their strategy to overcome the big ones right now such as Google Drive, Dropbox, etc. Seems like a really long way to go.
nissehulth · 2017-08-26
True, but if you visit a site like http://sia.tech/ , in my opinion it gives the impression of a product ready to use today. Though if you look at their roadmap https://trello.com/b/Io1dDyuI/sia-public-roadmap , you get another (more realistic) picture.
guy_c · 2017-07-20
Siacoins calculator at http://sia.tech/ is claiming a price of $2/TB/month vs $23/TB/month for Amazon S3.
However it neglects to include Backblaze's B2 storage which is only $5/TB/month - https://www.backblaze.com/b2/cloud-storage-pricing.html
That is maybe a not a big enough price saving to convince conservative corporations to switch. Imagine going to your accounts department to request they purchase a cryptocurrency so you can use it to pay for data storage.
jacoblambda · 2017-07-08
well, not specifically ethereum but stuff like siacoin provide cheaper options than AWS and while I personally cannot attest to the performance, they seem to be interesting alternatives.[1]
In the case of siacoin, at face value it seems to be significantly cheaper than AWS or Google Cloud for providing bulk cloud storage.

Klathmon · 2017-07-02
The people behind sia coin believe differently [0] and after reading that I'm more inclined to believe them.
The short version is that since "commodity" hardware can mine many things, you can't gauge how much power there could possibly be. Someone with 100,000 GPUs could turn their whole system to your coin and have over 50% of the hashing power for a day, then go back to whatever else the day after.
With ASICs, the devices can't be used for anything other than that specific coin, so to "save up" your hashing power to sneak in a day that you can get majority hashing power would be stupid. You'd have to be giving up the income from them while you waited.
The article explains it much better than I can, I really recommend it.

Check out https://golem.network or http://sia.tech
You rent out your unused CPU (Golem) or unused disk space (Sia) and get automatically rewarded

You could try out one of these new storage cryptocurrencies:
https://www.storj.io
http://sia.tech/
https://filecoin.io/
https://maidsafe.net/
I haven't used them myself so I can't vouch for the UX or quality, but they should be able to offer pretty low prices.
