Bitcoin Forum

Hello BitcoinTalk community,

We just started a new service: coinuploads.com (http://bit.ly/VwtCjp). You can store and share files for bitcoin. No registration needed.

It's beta so all feedback is appreciated.

http://CoinUploads.com (http://bit.ly/VwtCjp)

PS: We are strong believers of the Bitcoin and this is our first btc project. Need some encourage :D

Any chance you will support files up to 20GB in size in the future?

Does the uploading party have to own the files they upload?

Real nice concept - I hope it will be successful.

A few things about the info on the homepage, though:


"SHA-256 encrypted" doesn't mean anything - SHA is for hashing, not encryption. Please clarify.



Bad English - A slightly better way would be "Each download extends the availability of the file for another 30 days."

Cool. Could it be possible to upload files via torrent URLs?

It be nice to know how to you calculate how much a download will cost, is it based on size and what is it per unit of measure.

Hi Folks,

Thanks for the feedback.  :)


Absolutely yes. We will implement an advanced uploader soon (pause/resume, speed limit, etc). This is a must-have feature before handling large files.


The responsibility lies upon the user to not spread malicious, false or illegal material using the service.


You have right. It was a serious typo. All files are AES-256 encrypted.


Thanks for the correction. I changed the content. (As you can see english is not my first language.  :D )


Not in the near future. This feature is very tricky with the current infrastructure.


It's based on size by default but you can charge as much as you want (above the minimum transfer fee to cover our costs).

Seems like your first language is german...

Anyways: How are the keys for the files generated?

Edit:

Example link:
VLC 2.0.4
"Filesize: 21.9 MB (min. fee per download: $0.0213)"
I set the fee to 1 USD...

Hashes of the original file:
Adler32: 4C253181
CRC32: A3F07BE1
MD5: E03F2F24BCA457A35E1E26732AFE4A2F
SHA-1: 0A335D3B790FD4AE3371E73806B2CDF59FB384C6
SHA-256: EC2A1B497894D6B696953DD868B2894B6DEC2AAACCD259A8D80B167A36B9CB0C

This is illegal

well done great idea

Typo under "Earn Money", "Receive your it on your Bitcoin address after every download."

And I'm not an expert but I don't think a colon is appropriate here in the FAQ, maybe a semicolon or a separate sentence.

"Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network."

It's a random string not hash :)

I like it! I might use it to sell some products of mine later on!

Of which length and how generated (/dev/random, /dev/urandom, some library...)?!
How and where are these keys stored?

All in all the only thing that this encryption is good for is that if someone gets onto one of your storage nodes, the attacker still needs to break the database with your key(s). All the data can be decrypted without the uploader's knowledge by you and it gets transmitted in plaintext over the net... this leads me to https support: planned?

Also in the end all you do is provide a front-end to AWS... make sure you don't get a high bill because someone writes a script to upload billions of 1 byte files *cough*...

By the way:
I upload a file, don't enter a bitcoin address and close the web page - what happens?! File gets deleted, file gets deleted after 1 week, ...?!

would be very cool feature if you make it so we can list the download for free and put ads to make money in btc. for example using coinads or w.e.

He said AES-256, which means the key size is always 256 bits.


More importantly, where are your keys stored?

Quick update

Reddit discussion about CoinUploads (http://www.coinuploads.com):

http://www.reddit.com/r/Bitcoin/comments/12lviz/coinuploads_file_storage_and_sharing_for_bitcoin/

New feature coming soon: embedded downloads.

Let your website visitors pay and download without leaving your website.

Demo:
http://www.coinuploads.com/embedded_download.html

The secret encryption key is stored in the URL now. Not even us are able to decrypt your files without the key. This is a powerful feature.

videos4btc.info (http://www.videos4btc.info) just started to use our API. Very cool example how can you use embedded downloads.

Thanks, coinuploads.  Works very good have had a few purchases!  ;)

You two I wanted to talk to:
CoinUploads: I wanted to try your service but uploading a small gif fails. Tried another which failed the same way. Both result in a promising progress bar that suddenly resets to 0% and then at 60% again it shows an alert about a failed upload.
All the fuzz around Kim.Com should accept bitcoin got this thing started, huh? Wish you all the luck to get it smoother. A lot smoother. I guess it could be a mega big thing ;)

videos4btc: Showing 4 photos with nothing at all to it will not get your clients attention. Allow the girls to upload teaser material, a profile, a guest book, ...
Generally have the first 20s of videos for free or do something else to get your clients hungry. As is, it looks like a cheap scam to get people to send you some coins.

Thanks Giszmo! All the things you mentioned are in the works! Just getting it out there to start but I agree getting the clients hungry is a good idea!  Yes, was afraid people might think that :/ Thanks for the feedback.

I guess your service will be super successful if you do it right. My ideas of what might go wrong:

• The competition will have a nicer site online faster than you
• You run into legal fun over not paying taxes or child porn on your site

Thanks! I hope so also should give good exposure to Bitcoin!


There is always that possibility but I figured why not go out a on a limb and give it a go first mover type thing!


Taxes will be paid on any revenue earned. The site is monetized based on advertising right now.  We can prevent child porn for now because everything is manual for the moment just
for that reason but good point!

She is doing pretty good so far over $5+ earned for her so far (1) video clip and is in the process of making a few more. Stay tune and thanks for the support!

edit: another one should be popping up very soon!  I'll see if we can do " free teasers"  although I think the lowest coinupload goes is 1 cent?  so not totally free...

Agreed. And got what you meant ha.. ;D

Sorry, we are sort of hijacking coinuploads thread here ...

I believe the downloads are broken! :/

New features:

• Want to support the Bitcoin fundation? Just leave blank your bitcoin address and we donate all your earnings.
• Easy file uploads: just upload your file and set your price .
• Affiliate program (35% instant payout after each download): you can earn commission on other people uploads. Just put your bitcoin address at the end of the url (?ref=YOUR_BITCOIN_ADDRESS)

Very nice site! I had the same idea today, to find you guys already did it and made a very nice job of it :-).

I'm curious, how many files do you get per day? Do you have any other stats?
