I have a very strong academic mathematics background. 'scientific value' is a subjective statement. Most mathematicians would regard anything new or original as advancing mathematics. Do you think patterns in integers have scientific value? Depends on the pattern to an extent and if there are any clear consequences but you'll get varied answers to that question. Some mathematicians and especially scientists such as physicists are snobbish and only regard maths that has a 'real world' application as being useful. It's not clear to me whether this project is finding new prime chain sequences within the known prime numbers or actually trying to determine new, unknown prime numbers using the prime chains as a proof of work. Either way, it has value since it will add new data which will either disprove conjectures or strengthen the likelihood of them being true... plus the analysis of the discovered data could in theory lead to new conjectures (note I know next to nothing about these chains and how much data of them is out there, I'm just writing this reply of the top of my head).
You can also look at this another way. This project could provide a financial incentive for individuals to develop more optimised GPU prime finding algorithms, the theory of which could lead to a greater understanding of prime number distribution e.g. a new sieve or similar construct.
Sunny, can you please clarify whether this project is finding new prime chain sequences within the known prime numbers or actually trying to determine new, unknown prime numbers using the prime chains as a proof of work.
Of course these primes are all 'new'. Finding 'new' primes is not the point, and primes are super-abundant there is no database can store them, it's always trivial to find one not stored in any database. The point of GIMP is to find the largest known (Mersenne) prime, while the point of primecoin is to find longest chain of reasonable size limit (256 bits to 2000 bits as currently designed). Which one of the two projects is more useful is highly debatable actually. Mersenne has a very long history of study, its infinite existence is not known and they are scarce (only about 50 of them known). While for prime chains, as pointed out by my design paper, these prime chains are connected to the distribution of primes, their infinite existence and distribution is among the top wonders of arithmetic, you know how much mathematician value twin prime conjecture right? At right now I think some mathematicians consider the distribution of these longer chains hopelessly untouchable, and maybe will stay another millenium  Why didn't you up the max length to 2048 bits so we can eventually produce primes that could be used to undermine ecdsa? ECDSA uses primes up to size 2^256, right? 2^256 is WAY bigger than 2048. 2048 is 2^11. wait lol i confused myself up to 2000 bits would result in 2^2000, wouldn't it? So that's larger than ECDSA uses... Right? |

Nobody is going to bother with FPGAs this time around.
In the long term, more specialized hardware will always win out if not for hashrate, just for their power efficiency. If these projects are to become actual currencies ASICs will be the endgame for all of them. |

|
|
64-128K per thread doesn't seem that expensive ASICs might very well be possible.

"We have to stop ec2 instances"
"We have to stop botnets"
And why, exactly?
muh profit |

I have 48 cores in one machine mining but 0 primespersec after 20 mins. My other machines are all working fine
Each thread gets it's own sieve, you're probably running into cache issues. |

Has anybody made a GPU miner yet?
a GPU miner will drive up the difficulty and lower the block reward. We'll be dealing with the same exact shit again. What's the point? That people aren't mining in secret with them and getting 100 blocks for every 1 block you get with your CPU? I thought the block reward was constant. No, block reward decreases with higher difficulty. oh lawdy then my C++ skills are worse than I thought. What file do I even find the block reward in  |

to bash it later after they have dumped
...people don't actually do that, do they? yep they sure do. some people actually pay others to bash a coin when they have a post on the first page of a popular coin >mfw I have a post on the first page Looks like I'm getting a new pair of shoes. |

Perhaps higher clock rate is just better.

Hello! I got a $0.50/hour high-CPU EC2 instance (XL, which supposedly has 8 cores, all of Intel Xeon E5-2650 style. The max PPS I have seen is 30. It has been running over an hour. My desktop i5-2500k is doing much better. Any ideas?  Read the source of the coin to see why. |

Can you extract the prime numbers from the blocks?
|
|
|
|
|
It takes a little over 53 hours to mature?
|
|
|
|
I like how pretty the main site is, but then the explorers are not as pretty :c Will you be able to extract the prime numbers from the blocks? Since that is the main interest of this coin. |

if i restart pc do i need to type setgenerate again?
If you aren't using a .conf file, yes. |
|
|
|
|
I was gonna go ahead and post my .conf file, but I checked the folder, and I don't even have one.
|
|
|
|
wallet doesn't open without a .conf file though
Then you must be doing it wrong. I downloaded the setup file and simply opened the qt client and it worked for me. |
|
|
|
I'm having issues! Why can't somebody just post a .conf file? Id like to set this to start mining before i leave for work :/ it obviously needs one Just open the qt client, and open the console and type setgenerate true |
