Really cool, man! Another way to take an advantage of cryptos!

sounds good but if ppl start to store files in the blockchain, in a month from now we would need 50tb hdisks just for the nmc blockchain

It would probably be better to store the files somewhere else but use the blockchain to reference them somehow. +1 for a distributed pirate bay though Edit: I wonder if you could use it to store GPG keys instead of on the server at MIT.

lol okay you must be joking right? If this gets popular namecoin would become unusable very quickly. Time to raise spam fees I think Although seriously I have been talking about supporting database usage in ppcoin for a while. Now you just made me think twice about current transaction fee model to regulate the demand on block chain storage.

Yeah, I am very excited by this so excellent detective work running Yeah sunny, my thoughts were that if it can be done to namecoin then surely it can be done to any coin?? so this poses a potential threat to all currencies right? just as much as someone could 51% attack a chain with enough hashing power... anyone could also now bloat the blockchain with enough power / time and kill anyone with small HDD right and ruin the blockchain for that currency?

Well what if you stored the link to the attachment, and the decryption key, so that the file can be stored, encrypted, somewhere else, and you can find the link via NMC?

Couldn't you then also save Torrent Trackers to Namecoin as well?

oh I hope that it doesnt work on other blockchains

Also, there is some anti-spamming protection in bitcoin client. And lastly, miners can just ignore the requests if the fees are low enough. Which will probably happen anyway with namecoin if my way of saving files becomes popular. (people in general don't like illegal data on their disks. also it does not scale at all.) I am thinking of making some simple GUI to this, though. It is still too complicated with the need to run namecoind from bash and so on

NMC paid storage?

EndTheFed123, if you had just taken the money it wouldn't have ended like this BTW this hasn't been the real DPony13 since he "came back", I just hacked this account, SirLolicon is the real DPony13 I think.

It's much easier to do with namecoin via its API of 'name_new', 'name_firstupdate' and 'name_show'. With other coins there is no such api available so it needs to create the data transaction itself, and retrieve it back and parse it via maybe getrawtransaction, and it also needs to track transaction id and possibly embed some data structure to link multiple transactions for a file, or maintain its own persistent index. It's a lot more work but in theory doable. The only thing preventing a flood of data/spam is the transaction fee and maximum block size. Altcoins are more vulnerable to these issues because the fees are much lower compared to bitcoin right now. namecoin fee is 0.005 per KB, or 5 coins per MB, 5000 coins per GB. Given the current exchange rate, that's about $200~$300 per GB, not much money to cause real pain for the entire network. I am not really too worried just kidding. Still most likely ppcoin will eventually support database use like namecoin. And kudos to Running for the excellent work

Please do NOT use namecoin as arbitrary storage. This is not its function; you are risking irritating people enough to hardfork. At the moment, namecoin's growth is small and measured. I am fairly sure that the current users are not interested in storing your data.

AFAIK, namecoin can be used as general persistent key/value storage. (It is even encouraged on the wiki - http://dot-bit.org/Use_cases ) If it can be used as such, it can be used to store files, too, if they are encoded correctly. If miners won't want to accept these transactions they won't. Free market and so on.

That's dumb; there's 3GB of satoshidice crap on my hard drive because pools aren't shutting that off... Experimenting is fine, but this brings up the point of setting a reasonable fee on Namecoin for name registration again: http://dot-bit.org/forum/viewtopic.php?p=2954#p2954 and for pools to pick up such a new version when it is released. The cost of a name is about 25 for a USD penny.
