I'm not sure if there is some files already in the blockchain,
But I think it could be great if the first document to be included in the blockchain (or the first "official" one if there is some already)  have a strong symbolism.


Maybe some really important history document :
http://en.wikipedia.org/wiki/Declaration_of_the_Rights_of_Man_and_of_the_Citizen
http://en.wikipedia.org/wiki/United_States_Constitution

But i'm not convinced about those, it's too much linked to a specific country, when Datacoin is an universal and worldwide storage.


But i think a book is better :

For example , Fahrenheit_451 by R. Bradbury would be very symbolistic.  ( http://en.wikipedia.org/wiki/Fahrenheit_451 )
"The novel presents a future American society where books are outlawed and "firemen" burn any that are found, The title refers to the temperature that Bradbury understood to be the autoignition point of paper.[5][6]"
" In a 1956 radio interview,[7] Bradbury stated that he wrote Fahrenheit 451 because of his concerns at the time (during the McCarthy era) about censorship and the threat of book burning in the United States"

The book is about censorship and the destruction of knowledge, two things Datacoin will fight with his permanent and decentralised storage


It could be a sentence/quote too.


Give your idea :)

Unfortunately, the first document has been stored already.

This document is:


or translated to:

It's doesn't really matter.
It was more a test than anyhting else.
I'm talking here about a real upload with a real purpose

How useful is the block chain in Datacoin to store data?

What kinds of files can it store? How large of files can you upload?

Is it easy to upload/download them from the block chain, or does it take many steps?

I'm somewhat interested in this concept.

A copy of the first Matrix film.

1. Blockchain is expensive and reliable storage. It costs 50 DTC per 1MB , or 0.05 DTC per 1KB.

2. It can store any file, you need to bzip data before sending to blockchain. You can do it manually, or with special services (see below)

3. Now you can go to https://krypte.net , register here, send some coins and upload files. If you want to do that via wallet (Linux version), you should look into instructions http://datacoin.info/index.php?id=technical-details
This feature will be implemented into wallet GUI soon.

Bidji, you gave excellent idea. It will be very helpful and symbolic to get such document into blockchain and announce info about it via different news portals.

For now, it's not really easy to do because the coin is new.
But there is a lot of tools coming, like : https://bitcointalk.org/index.php?topic=365165.0
This would make it really easy to upload and download data from the blockchain.


Even is it's not impossible, it's not really convenient to upload files that large on the blockchain. Text is really where it's at, and photo too, but for videos it's too much.

“Run for your life from any man who tells you that money is evil. That sentence is the leper's bell of an approaching looter.”
― Ayn Rand, Atlas Shrugged

Let's wait for the new envelope protocol before uploading the matrix ;)

Well, in fact you can upload any kind of document to the blockchain, it is obviously advisable to compress it in some form (bzip, zip, rar, 7z, whatever) before uploading because of the fees.

Yeah, bzip is not restriction, but it really helps.

Matrix was a little joke, ofcourse it's a bit too large (for now  ;D). Fahrenheit 451 is an excellent idea. Catch-22 would fit very well too.  :D

I like the idea of this coin, I see it as a decentralized WikiLeaks of sorts. :)

Thanks for the info

yeah,  the blockchain can be used to store wikileaks doc

You don't actually need to bzip it, but you would be wasting transaction fees if you do not compress the data.

There is a lot of potential with this coin.  You can use it to store html files that can then be processed directly from the blockchain utilizing a special client.

You would need to store the data in a certain way.

Something like:


Bzip that and store it and someone could easily extract the file from the chain, parse the title using the identifier above, and display it.  Really the possibilities are endless.

Other ideas that you can use it for are private messages encrypted with a certain key.  Then the two clients can send untraceable encrypted messages that get decrypted by the clients at either end.

I agree. I think free (copyright expired) ebooks should be stored early on. I would donate 10 DTC to the unofficial team if someone took it up.

Candidates (bzip compressed 50-200 KB / book):

Moby Dick: http://www.gutenberg.org/ebooks/2701

Beowulf: http://www.gutenberg.org/ebooks/16328

Alice's Adventures in Wonderland: http://www.gutenberg.org/ebooks/11

Les Misérables: http://www.gutenberg.org/ebooks/135

I have just uploaded a poem (encoded in html without compression).

The Bible

LOL why not ? It is one of the best novels ever written, and a best seller of course  ;D

Did you actually read it? I've stopped after 50 pages. It's unbelievably boring. Like reading a phone directory.

Just a question that probably is in the documentation, are the coins destroyed or go to miners in next blocks??

Transaction fees for storing files go to the Miners.

we can choose multiple books, and then include their TX IDs into all Datacoin promotions, just like proof-of-concept.

I think this was a good choice of words for testing, could of been: lets see if this mutha works...

Why not load up a list of the founders names and a bio to go with it, in this way as the coin moves in a direction away from them or givin time they are givin due credit for their work.

George Orwell «1984»

Going off of the Fahrenheit 451 idea, if you just wanted to use quotes instead of the whole book I put this one up for vote:

"Peace, Montag.  Give the people contests they win by remembering the words to more popular songs or the names of state capitals or how much corn Iowa grew last year.  Cram them full of noncombustible data, chock them so full of 'facts' they feel stuffed, but absolutely 'brilliant' with information.  Then they'll feel they're thinking, they'll get a sense of motion without moving.  And they'll be happy, because facts of that sort don't change.  Don't give them any slippery stuff like philosophy or sociology to tie things up with.  That way lies melancholy.  Any man who can take a TV wall apart and put it back together again, and most men can, nowadays, is happier than any man who tries to slide-rule, measure, and equate the universe, which just won't be measured or equated without making man feel bestial and lonely.  I know, I've tried it.  So bring on your clubs and parties, your acrobats and magicians, your daredevils, jet cars, motorcycle helicopters, your sex and heroin, more of everything to do with automatic reflex.  If the drama is bad, if the film says nothing; if the play is hollow, sting me with the theremin, loudly.  I'll think I'm responding to the play, when it's only a tactile reaction to vibration.  But I don't care.  I just like solid entertainment."

5 books just for now :)

Great idea! I vote for "1984" and "Fahrenheit 451"!

It's so good for promotion of datacoin! Where all guys from anonymous group? It would be useful for them :)

We should not include copyrighted books. That's a bad idea for a start.

p.s.

Don't forget to vote for Datacoin:

https://bitcointalk.org/index.php?topic=359521.0

Yeah! But we could use quotes  :)

Are these books non-copyrighted ?

copyright expired

Copyright expires 70 years after the death of the author. So you can read/use/publish the 4 books I've suggested for free.

Good, I'll think about more books with expired copyrigth

1000 of them are here for download:

http://www.gutenberg.org/catalog/

So we need more suggestions from the community - maybe 10 books total to be uploaded :)

Maybe because of my origin country i would like to see Homer's Odyssey

Now this is a good list http://en.wikipedia.org/wiki/List_of_books_banned_by_governments if we want to be a little aggressive :P

Btw seriously personally i wouldnt like to see Bible there as one of the first books. Maybe i would prefer the On the Origin of Species before any religious text...

If i would have only 1 choice i think i would choose Newton's Philosophiæ Naturalis Principia Mathematica ...

+1 the Bible is full of hatred

I +1 this. How do you go about putting data in the chain? Very intriguing..

You can do it yourself using command line tools, or register at this website and use the UI to upload any files you want to the blockchain (you pay in DTC for the upload):

https://krypte.net/

Downloading is easy.

And if you want something to have some sucess in europe just make a little mp3 with this "Ode to Joy" http://www.youtube.com/watch?v=ax9SOup0054  ;)

Gotta say, DTC is a very, very, cool coin.

what do you think: should be books uploaded now, but split into chunks (as zip chunking), or should we wait until 'big file' functionality is finished?

With good compression a lot of books will fit into 128KBytes!

can you give me links to such compressed books?

You can compress them yourself.

At http://www.gutenberg.org you have thousands of free books in multiple formats.

I've already suggested a few books in this thread.

Compression example for Alice in Wonderland:

1. Downloaded as plain UTF-8 text from here:

http://www.gutenberg.org/ebooks/11

size: 164KB

2. Compressed using zip (strongest compression)

result: alice_in_wonderland.zip

size: 59KB

uploaded the file here: https://mega.co.nz/#!scRmSTQL!dQyGWwaitmOjyfpoSv_wLTXAjkZBKfL5ogTldF7Me1E

smite for your mockery of the Book
