The internet traditionally uses location-addressing. A DNS name pointing to a IP which has a specific location your computer tries to reach in order to fetch the content. This means that particular node needs to respond to you, and the bandwidth is depending on the bandwidth available on the particular path to that specific node. Instead, IPFS uses content-addressing, where the content is hashed and given a ID based…

Caches solve this placement problem just fine today and content addressing does not alleviate the placement problem at all. Reality is the space thing is just part of the usual crypto grift narrative building.

Being able to arbitrary place caches anywhere and let anyone serve the data, and you can trust you're getting the right data, is a huge benefit over location-addressing. Ignoring IPFS, content-addressing makes sense for so many things, which is what lots of storage/caching/CDN solutions have discovered decades ago.

Content-addressing is nothing new (nor did Protocol Labs/IPFS "invent" it) and if you're using a CDN to serve content today, the CDN is with 99% certainty using content-addressing at least internally.

Torrents with extra steps, eh?

As chance would have it, an excellent deep dive into the differences between IPFS and Bittorrent was published by Daniel Norman today.

I'm still a little lost. Could someone more knowledgeable than me explain how operations in space would benefit from a public content-addressable filesystem? This seems like the kind of application that works best when bandwidth and storage are cheap, and I would have assumed that that, in space, both are about as far from cheap as you can get.

How do you mark something for deletion?

Or once its in the network thats it?

Seems easy to DDOS by changing one character many times in a file which generates a new id each time

Maybe I missed something obvious, but does the IPFS project itself say anywhere that it does "file preservation"? The only thing I can find from official resources is documentation saying IPFS does not do that at all. Example from https://docs.ipfs.tech/concepts/what-is-ipfs/#what-ipfs-isn-... > What IPFS isn't > IPFS is not ... A storage provider: While there are storage providers built with IPFS support (typically…

The only times I've seen IPFS being brought up in the interned discussions was by people who claimed that their token startup will guarantee preservation of some data via IPFS. This was also a usual argument in comparisons to commercial cloud storage. Reading your link I don't quite understand how come they claim IPFS is both a protocol AND a network of nodes AND not a storage. For example TCP is a protocol, but TCP…

libgen uses ipfs. books on ipfs are a great idea.

Filecoin is probably one of the few cryptocurrencies with intrinsic value, even if the amount is debatable. IPFS has stood the test of time and seems like a good protocol; and a cryptocurrency that can be used to pay for storage is not valueless.

> Filecoin is probably one of the few cryptocurrencies with intrinsic value, None of these coins have any intrinsic value. There are thousands of people who sat on bench and thought, "I want to create a ponzi coin" doesn't mean they create value. Crypto is a net negative phenomenon.

I'm pretty cynical of crypto, but you're confusing what something can be used for with what it can only be used for.

Any coin, including USD, has no intrinsic value. Its value is in what people can buy with it.

I have uploaded files about 3 years ago to ipfs and somehow its still there.

Unfortunately I have to repeat what I just wrote word for word: "there is no GUARANTEE about file preservation there at all (unless you pay to people hosting your files specifically)" Sure your files are accidentally still present in the cache. Good for you. The problem is deceiving other people who may think it's somehow spacemagically-interplanetary guaranteed.

No reason to repeat yourself. I was surprised that it was still up. I knew very well they were likely to dissapear. I assumed it would have been gone by now.

OK. But, going back to my comment about cheap. This claim: > The benefit of this is that you can fetch the data from anywhere Only works if the data I want is being replicated in many locations. But storage in spacecraft is presumably a tightly constrained resource, due to the need to use technology that's space-hardened and has an extremely good reliability record, and is therefore probably far from being both cutti…

You're asking why a superglue company would superglue a construction worker to a steel beam. Its promotional material.

Huge achievement. A big, big stepping stone toward interplanetary communication. But while I love the idea of IPFS, it comes with a bunch of tradeoffs that I think make it very unlikely that it'll ever become mainstream. What I do think will happen in space, is similar to what already happens with PoPs around the world, no IPFS required. As an example: I believe that there will be a YouTube on the moon and YouTube on…

> What I do think will happen in space, though, is similar to what already happens with PoPs around the world. As an example: I believe that there will be a YouTube on the moon and YouTube on Mars, and YouTube servers caching most of the content on both, and it'll all work the same. Cross-planet communication will be high latency, but it won't matter. Importantly, this is enabled by content addressable storage in IPF…

> Importantly, this is enabled by content addressable storage in IPFS

Can't it be enabled in all sorts of ways? E.g. edge caching, the way YouTube works today?

I think the idea behind content addressable databases like this is that they are supposed to be permanent. Putting it out into space may be a way of saying "its never going down".

It’s only not going down if the content is actually present in such nodes. It’s not.

Its just a router node?

The kings of marketing and buzz-words at it again trying to re-spin CDNs as their invention. IPFS doesn't solve persistence of data; doesn't solve churn in p2p systems; doesn't actually 'store' anything. Sounds cool though! Space and shit, some-thing, something 'decentralized' --hand waving-- 'space', umm, can I have money now? I'm doing it.

I don't think IPFS is a CDN in the sense I know it as, e.g. Akamai. Isn't it meant to be run by end-users instead of a central company?
