Cost of storing data on SAFE?


Is there anything known about the cost of uploading and/or storing data?
I know MaidSafe is not live yet but are there ballpark figurs?

For instance, we know what AWS, Dropbox, Azure or others charge for storing data but do we know if MaidSafe will be competitive in terms of pricing? (aside from the fact that the fundamentals and security of Maidsafe are a lot more attractive).

For our average Joe, who does not know a lot about security, or does not care about it, I wonder what the incentive would be to pay more for a service that would do the same, e.g. storing their pictures (think of something “simple”).


Quite unclear to me as well. Some algo’s will figure out how the network is doing. Here’s another topic about it. But still, no clear answer to your question:

Initially, the upload cost will be based directly on the farming rate. This may be tweaked later after there is a better view of how the network is behaving. More info here:


“Where 1 is a 1MB chunk. It is assumed the figure will alter under scrutiny of network testing, but this is assumption (based on usage increase (X10 pa total), price decrease (1/2 pa) etc. over time) as well as b/w usage, which widely varies across countries at the moment.”

What’s pa? Thnx :smile:

Per Annum (yearly, in this case approx)

I wonder, does one have to pay to store files that are exact duplicates of files already on the network?

Nope, you don’t. (filler filler)

Scenario: I see an amusing jpeg with witty oh-so-sarcastic caption on twitter - save the file to my desktop in readiness for quick-fire response for when some schmuck needs an instant put-down.

Days later I remember I havent backed up for a while so my desktop and other famly jewels duly get rsync’d to the SAFE network.

Now I expect to pay for the contents of my docs folder etc etc but when I save my desktop I DON’T pay for the amusing .jpeg cos someone else is way ahead of me and has already saved it elsewhere.
How quickly can the network tell that the exact same .jpeg already exists on the network and am I charged and later refunded for a duplicate?

Question: Can you modify files while they’re on the SAFE network? Say I uploaded a document or music file on the SAFE network and wanted to edit the document or say change the id3 tags of the music file so it had the artist listed in it, would I have to reupload the entire file or just get charged for the changes made?

You’ll be charge for the extra storage the change consume. So if only one chunk of the file is affected, that’s what will be charged.


How is the file subdivided? How do you tell? Like say I had a text file (or Word Document) and went in and edited a chapter, or ammended the end of the dommument or something. How does that translate into chunks?

It will be broken into chunks, then the chunks that differ will need saving. If someone else has already saved that new chunk, It won’t need uploading again.


It will happen at network speed, as it is a read/get request on the chunks that make up the file.


Your file index map will change with the new chunk’s index replacing the old one. So now you have two versions of the file. The old index map and the new. (index map is not the correct term but I cannot remember the right one at the moment). If I am wrong can someone correct me.

Is that possible? To affect only 1 Chunk? I thought changing only 1 bit of a file would affect the whole file including all the Chunks…

Flipping one bit should result in two different chunks; chunk (1) containing the flipped bit, and chunk (2) being encrypted with the hash of chunk (1). Inserting an extra bit will cause a chain reaction though for all consecutive chunks, causing them to have different hashes. In that case those chunks and the very first one (since it’s encrypted with the hash of the last chunk) will be different.

Depends. if I’m not mistaken, if you modify the information which affects only the chunk N will modify the chunk N-1 and the chunk N-2 too. The N-1 because you modify the AES256 encryption of this chunk N-1 based in the chunk N. And the N-2 because you modify the data of the XOR encryption of the N-1. The rest of the chunks remains intact.

Of course if you append a single bit in the beginning of a file you can change all the following chunks.

You just got ninja’d! :smiley:

Actually, I thought N-1 is both encrypted and XOR’d with the hash of N. N-2 should be unaffected. But perhaps that has changed, I’m basing myself on the self-encryption video.

I’ve read most of the papers now but still there is no answer, not even an estimation of what the cost of storing data on the Safe network is.

Besides the tech being real cool, this is a serious issue. How will MS attrackt followers and developers if we have no idea whatbthe cost will be?

Is there anyone who made hypothetical calculations? I would just like to know if storing data on safenet is competitive to google, amazon or any other large cloud vendor (that is besides all the benifits of added security which you avarage user simply won’t understand)
