Title: Can the Hashes from block generation be useful? Post by: kokjo on April 25, 2011, 05:46:02 PM can they for example be used in cryptographic research, or anything else useful?
or are they just completely useless? Title: Re: Can the Hashes from block generation be useful? Post by: Garrett Burgwardt on April 25, 2011, 06:09:05 PM If you collect the hashes, you're almost generating http://en.wikipedia.org/wiki/Rainbow_tables
So potentially they are as useful as a rainbow table, though whether you think that is a good thing is up to you ;) Title: Re: Can the Hashes from block generation be useful? Post by: MoonShadow on April 25, 2011, 10:54:30 PM random entrophy data for a cryptographic stream cypher?

Bitcoins themselves have value since they can be used to slow spammers down. http://en.wikipedia.org/wiki/Proof-of-work_system Title: Re: Can the Hashes from block generation be useful?

Bitcoins themselves have value since they can be used to slow spammers down. http://en.wikipedia.org/wiki/Proof-of-work_system but can the hash-to-blockdata mapping be used for something else. i mean all thees 0's in the beginning of the hash, can they be used for something? can all the hash-block pairs be used for not just generating btc? it is not everyday a cryptografer haves a 960.36 ghash/s network, which is generating a lot of 0's Title: Re: Can the Hashes from block generation be useful?

I answered this in another thread. Block hashes serve as the hashing community's signature attesting to the completeness of the block chain. The strength of the hash on a block and its subsequent blocks is what gives receivers confidence that their coins are not double-spent. By hash strength, I mean the "number of zeroes" or difficulty score. They are not useless at all... until someone breaks double SHA-256. http://bitcointalk.org/index.php?topic=6459.msg98999#msg98999 Title: Re: Can the Hashes from block generation be useful?

That depends if bitcoins are useful or not. It's my opinion that bitcoins have the potential to improve the world in ways that far outnumber the rest of the distributed computing programs combined. But I'm an optimist. Title: Re: Can the Hashes from block generation be useful?

Nice. thats good. :DTitle: Re: Can the Hashes from block generation be useful? Post by: John Tobey on April 30, 2011, 03:13:38 AM i know that. but anything not bitcoin related? Ah, then I must confess a lack of curiosity. It's a little like asking what an automated teller machine is good for, other than money-related things. If it's heavy enough, it might protect you from a stampeding herd of elephants. Kind of like the lotto application, mildly cute but shrug-worthy.
