Happy to know Dirk likes primecoin and I just sent him a note. I have also contacted Henri and Jens as well  Smiley

Most people only know about the largest known prime record (aka the k=1 record on Jens' list) which is dominated by GIMPS (Mersennes). That's why Jens' record book is important so that people realize that Mersennes are not the only primes of interest to mathematicians.
Nice, good work keep it up Smiley

If primecoin proof of work is just probability of being prime, so how can you prove that a found blocked is really a prime number ?

I think the chance of the primes not actually being primes is supposed to be extremely small, but I haven't looked into it. I know that someone double-checked the first couple records at least.

So for the miners of #2044 and #5355 please step up and give us a proof you are the miner and the name you would like to be written for the record book Wink

To look up if you are the lucky miner who mined a new world record you can go to help->debug window->console and type
validateaddress <record_holding_address>

There isn't a quicker way to do this? Tongue

I agree... there should be an easy way to scan all your found blocks to see if they are record holders.  esp with the constant finding of new records.  who can keep up with all of this, much less enter in every new address against these records.

is there a .conf entry that will auto sign all of my mined blocks?

NOTE: Your wallet will need to be unlocked while you run this code. A simple modification to the script could unlock your wallet for you, but then you would be saving your wallet password in the source... Also, you might want to change your name on line 20 (unless you want to sign your world record over to me  Grin)

NOTE 2: This new code prints out the history of records found by Primecoin. To get a complete picture, you'll need to delete your existing worldrecords.txt and re-scan from the beginning of the block chain.

My block crawler displays them:

http://primeblock.kicks-ass.net/

If you want the source, you can download it here. You need a primecoin daemon and need to add your daemon connection information in bc_daemon.php, you also need to ensure you have the GMP extension loaded.

I'm sure you could convert the code to some other language easy enough also, the relevant code is in bc_layout.php.

FYI I just pushed a new command 'listprimerecords' to repo for checking the records.

This gives primecoin internal records, by length (simultaneous primes) or by type.

To find records of simultaneous 10-primes:

listprimerecords 10

To find records of a given type:

listprimerecords 11 1CC
listprimerecords 11 2CC
listprimerecords 10 TWN

Thanks, its too complicated for the average miner to figure out if they are record holders.  An easy command to do this would be great!

Now listprimerecords shows an 'ismine' field which indicates whether you are the miner of it.
It would be included in v0.1.2 release build soon!

Are you going to improve mining efficiency at all in the next release build?
