I think this is the main technology behind that and it is open source… I heard something about it years ago too. I’ve similarly never used it and am curious now that you mention it if anyone has. I’m unsure how to actually “use” ipfs and/or what tools might use it.
I’m kind of inclined to believe it doesn’t work (or doesn’t work well) otherwise it probably would be a bigger deal by now and there would be a lot to show off on the ipfs website.
Edit: It looks like this provides S3 compatible storage to IPFS. However, it seems more expensive than B2… So I’m not really sure why one would use it. You’d think IPFS would be attempting to undercut traditional providers.
