@bzyzny I agree, just have to understand the theoretical collision attack for SHA1 and how SHA2 solves that. How is a hash algo developed, by trial and weakness detection or do they "calculate" the theoretical strength somehow?

Yes, well that's the point of all this, we didn't think we could have distributed "double spending safe" transactions either...

its silly and could still have an asic would just be an expensive one to have made  what miner is going to spend days/weeks building a bitstream for each diff change would never get any transactions done Ok, you are missing the point. You wouldn't make the bitstream manually it would be transformed automatically by the client (tools that don't exist yet). You would have to invent stuff! The point of the exercise: make a hasing algo that can't be ASICifyable because it changes and the parts that change have to be in the silicon to be performant. Wait, this is a bounty! I would easily pay 5 btc for this, anyone else? |

That's the thing, I don't have time (or the brains) to do this but I'm sure it's possible, using custom tools and whatnot. Someone out there is most certainly already working on it, and the rewards will be huge, think Bitcoin 2.0

See this is how I know this is a good plan, there is room for improvement. I don't even know if it's possible, but I have the feeling this is where crypto currencies could evolve towards!
have you ever used Xilinx ISE to do a build for FPGA or do you use the pre-built bitstreams only? No, only used pre-built stuff. That's why I don't know, if I knew I would have tried to build a "dynamic" hashing algo already. But I can imagine you need some core elements, that could be provided as inputs to the "ASIC" to be required inside the "ASIC" for performance reasons. "ASIC" = the bitstream |

if you mod the algo dynamically like you are saying its not going to be power efficient as you are trying to create resistance  and if you can put it on FPGA then some part of it could be put into silicon! Yes, but if you modify the bitstream you would have to make a new ASIC. So I suggest inventing a new hashing algo that requires a new bitstream every difficulty change (or so) not like quark (that uses a set of known algos) but a totally new and fundamentally dynamic algo. quark uses an awful waterfall method for its algo's its terribly inefficient! try building the bitstream from source via Xilinx ISE and then think about it again takes days/weeks to get a good fmax build  See this is how I know this is a good plan, there is room for improvement. I don't even know if it's possible, but I have the feeling this is where crypto currencies could evolve towards! We need hashing, so we should improve hashing! |

So the more exchanges, the lower the price? |

so when scrypt/asics come out and when GPU's become redundant for scrypt mining. Do you think people will turn to blake-256?
edit: scratch that thought, the new FPGAS will take over and be an ASIC like race all over again.
Just look at the name Asic = Application-specific integrated circuit No algo can avoid getting an Asic if the demand is there That's why I have always said it is pointless to be resistant, if an Asic was done for Blake-256 due to not trying to be resistant it would be a smaller chip that is cheaper to make and uses less power yet would also have a fast hashing rate e.g. it would be faster than the current SHA-256 at the same manufacturing process Blake-256 = Small, Fast, Simple, Power efficient  I also like FPGA's they are re-programmable and lots of ex-SHA-256 boards about that can be reused for Blake-256  This is where I think one should just appreciate the flexibility and power efficiency of FPGA and build a coin that modifies the hashing algo in such a fundamental way every difficulty change that it can't be made into an ASIC. Blakecoin is a great hedge against weaknesses in SHA256, that's it really (just like any non SHA256 altcoin). But I agree that litecoin miners will probably move to any non SHA256 or scrypt mining if the price of those currencies doesn't rise as that hedge is worth something. |

Use ny1.blakecoin.com as backup!
I have eu1, ny1 and solo in that order.

Hey, why does openex.pw say trading will stop on friday?
|

|

Here is my USB collection.  Hey, we think alike, what are the two weird ones (3rd and 4th from left)?  I got the original heatsink for that BE!  Edit: to the moderators, this new image thing is broken because it doesn't cache properly! |
|
|
|
Now I have eu1, ny1, and solo in that order. Can't believe I only mined one block in 24 hours with 1.6GH!  |
|

Found my first solo mining crypto currency block ever at 5:13 this morning! I like it!
Does anyone know how much bandwidth the wallet consumes?
Will "no-submit-stale" remove all the "Share below target" in the log?
Generally is there another "better" way to solo mine than JSON RPC over HTTP with the blakecoin-qt?
|
|
|

Pool eu1.blakecoin.com is down!
Do we have any other working pools?
You can try to solo mine it. Now I am, good thing I don't have to wait two years to see if it works like BTC, should have a block soon with 1.6GH... |

FYI, bitstamp payment came through day after, lots of costs though ~38$ on a 500$ transfer! Don't know which of those where fixed costs and how much was "fraud" bankster exchange rate to my local currency...
Does bitstamp have an upper limit per day and month like MtGox?
|
|
|
|

Gox is only price lead as long as volume is highest, you cannot use it to retrieve fiat, they are super slow to authenticate users and accounts. > 2 months. I did test transfer with bitstamp > 2 weeks ago havent looked if it came through yet.

Use your zTex to mine blakecoin!

Is this the only coin you can mine with FPGAs except BTC?
