I am currently playing around with the idea of creating a blockchain to store data in it, be it messages or files or whatever. Just hugely increase the storage space for transaction data and add the data to the tx, right (OP_RETURN in Bitcoin and most Altcoins)?

Do you think it is worthwhile to seriously work on this? In my opinion there are many advantages, the biggest one: The data can not be censored, which is an interesting change from most of the Internet. Upload a file and it will be there forever!

I forked a Cryptonote coin to test if this is even possible, check it out here (Testnet): https://bitcointalk.org/index.php?topic=1835332.0

And why has noone tried this yet?

[testing]

Infocoin aims to provide an uncensorable space for storage of information directly on the blockchain, a space to safely store messages, files, forums, anything.

For this purpose I cloned Cryptonote, increased TX_EXTRA_PADDING_MAX_COUNT from 255 to 102399, set the initial block size to 150KB and adjusted the blocksize growth to 20% per year. That means you can store up to 100KB per transaction, ofcourse you must pay a fee for which the optimal values will have to be found. Also the block reward is a thousandth of most Cryptonote coins (~700 initially). If these are sane values will have to be tested for sure, I'd also like to hear your input on these. Should feedback be positive I'll do an embarassing test release.

I am a noob when it comes to coding and forking coins, so I followed https://cryptonotestarter.org/inner.html for the most part, who have done outstanding work. Not sure if my changes will have the desired effect or break anything, so there will be a test release, to find out if the idea is even achievable.

Why did I go with Cryptonote? Well, because it's the only coin I was able to successfully fork so far. A Bitcoin clone might be way more suitable for this idea because of OP_RETURN seeing plenty of use already, so there are many ways to insert data into and retrieve data from the Blockchain already. TX_EXTRA doesn't see much use in Cryptonote coins so far and thus there is not much info to be found about it. I don't know how to insert data into the TX_EXTRA field in transactions, it is possible however (one likely needs a modified wallet to do this): http://monero.stackexchange.com/questions/1381/how-are-the-various-tx-extra-types-formats-used

If you are an experienced dev and like the idea, feel free to help or even take over. I just want to make the idea popular because the implications are pretty huge. It could be possible to e.g. make a forum that is impossible to censor, upload files, directly reward good posts. Astroturfing would be expensive as well, the fee should provide quality and security. So this is basically just a thread to see if the community likes the idea.

Also, yes, there have been a few Infocoins already, all seem dead and they didn't come close to the name anyways.

TO DO before release:
Find a way to insert data into transactions (tx_extra)
Explore other options besides Cryptonote
Seed node
Windows Wallet
GUI Wallet
Testing, testing, more testing

edit: TEST RELEASE in fifth post! https://bitcointalk.org/index.php?topic=1835332.msg18269690#msg18269690

edit 21st July: Network for testing is up and running.

PS: Why has noone tried this idea yet?  

Habe 2.5BTC zu verkaufen, am liebsten heute noch. Wohne im Wedding, wäre aber auch bereit durch Berlin zu gurken.
Der aktuelle MtGox-Kurs minus 2% wäre mein Preis. Von mir aus auch kleinere Mengen ab 0.75BTC. 

Want to sell 100 Primecoins, 0.01 BTC or 0.3 LTC each.

Post your Ferretcoin address and recieve 23 Ferretcoins.

Seller is not me. I was interested in buying it, but can't afford to do so. Going by this info http://www.dinigroup.com/~mdini/Bitcoin_mhash_FPGA_guide_v1402.pdf ,  each chip should deliver ~180 MHash.
The seller has more of these boards but at a much higher price, one even with a loose chip. Too good to be true or probably broken? Listing says pulled from working equipment.
There are more cheap FPGA board to be found, e.g. http://www.ebay.de/itm/Xilinx-HW-S6-SP661-OPT1-1-board-/111092117484?pt=LH_DefaultDomain_0&hash=item19dd9b2fec , i think that's a Spartan 6 Board for 50$, couldn't find the part number at Xilinx though, so no way of knowing what exact chip is in there (unless someone of you knows or finds the number).

Your thoughts please.

_{If this link made you rich, tip me}

Zahle 0.15 BTC oder 15€. So eins hier:

Want to sell:

343 FC2 Firecoin2/Feathercoin2 1 LTC

450 SRC Sunrisecoins 2LTC

6.77 DBL Doubloons 1 LTC

80 PWC Powercoins 0.2LTC

9.5 BTG Bitgems 1LTC/3BTG

Scammers go away, this is all pocket money anyways.  
Feel free to make offers. Also accept BTC and YAC.

Finally got around to setup my own pool at http://81.17.30.113:19327/static/

located in Switzerland
based on https://github.com/skralg/p2pool-feathercoin
2% fee

Host: 81.17.30.113
Port: 19327
Username: Your Feathercoin address
Password: x (or anything else)

Note that this is my first pool and bugs and mistakes on my end are to be expected. Won't secretly raise the fee though...  
0.61% DOA right now but i only got 150 kh pointed at it. If you see something that's not right tell me please. Planning to add CNC, but there seem to be too many problems with P2Pool and that coin, impossible to get stable payouts... That's why i chose FTC for the start.  

Cheers, happy mining!

Edit: Woot 500 khash now! Thanks mysterious 2nd miner!

Breivik hid 46 unvalid URLs in his "manifest", which contain geocoordinates plus some so far unknown code. Example:
http://52.068.4.309plusf24:KWimfhh436383717863МБ
http://59.334.18.097plusf87:RQqljii569218397413КЂ
http://48.200.16.356subf37:ILmeavp123271869374ШИ
full list here: http://app.homelien.no/~oystein/manifurls/urls-unicode-ordered.txt

There were various maps made on base of the coordinates:
http://maps.google.com/maps?q=http:%2F%2Fgoo.gl%2FF2HAE&hl=en&sll=48.0225,6.322&sspn=35.24582,64.643555&z=5
The blue area around each point is the valid area, since the coordinates are not very exact. Many think these might be terror attack sites for some so far unknown terror cell which stood in contact with ABB. An effort was started to crack the codes behind the coordinates, not much has been acchieved so far, a lot of known algos have been proven not relevant though.
I recommend you read through the mailing list a bit:
http://lists.homelien.no/pipermail/manifest-analysis/

Lots of speculation on why these places could have been chosen there, some examples:

The Munich coordinate is right next to the SPD headquarter for Bavaria
One of the Brusselless coordinates (50.832°N, 4.364°E) points to a district with a large congolese population, it even got his name froma place in Kinshasa, Congo: Matonge
The one in Hamburg is near to a university
The Amsterdam one is near a mosque

and so on...

Now my question is this: Do you think it would be smart if some bitcoin/maths/programmer pro would write a bruteforce tool to decipher the so far unknown meaning of the codes behind the coordinates? Or maybe someone is so smart and recognizes what these numbers+letters+serbian(!) lettes could mean. I for one have never seen anything like this, but i´m no pro at all.
