Title: [XPM] Primecoin Record Books
Post by: Sunny King on July 10, 2013, 04:57:23 AM
I am thrilled to see the level of enthusiasms for primecoin in the mining market. I suspect maybe we already broke some world records but hadn't the time to fully research this. So I hope more of you can keep an eye on this and keep the record book updated  ;)

The Cunningham chain record book is maintained by Dirk Augustin here:
http://users.cybercity.dk/~dsl522332/math/Cunningham_Chain_records.htm

The bi-twin chain record book is maintained by Henri Lifchitz here:
http://www.primenumbers.net/Henri/fr-us/BiTwinRec.htm

Upon a quick examination I have found that 2CC09 is the first world record claimed by primecoin:


Block #2044 New World Record for 2CC09 (131 digits)
Block #5355 New World Record for 2CC09 (158 digits)


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 ;)

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>

If the validate shows 'ismine' as 'true' that means you own that address.

Note: Since v0.1.2 one can use the 'listprimerecords' command to quickly check ownership of the records. The 'ismine' field indicates whether the wallet owns the given record.

You can check and verify these records at http://primecoin.21stcenturymoneytalk.org/ (http://primecoin.21stcenturymoneytalk.org/) (primality tests and queries through Wolfram Mathematica courtesy of Petr1fied)

In your definition we have bitwin chains with an odd length. Could you explain how to map that to Lifchitz's records table? Does length 9 mean only 3 links?

Code:
{
    "hash" : "02a74e2d1e1ce73167bdd2a510febd3ca635ac5a7c700dfdd65b5b19ff0d85ad",

Bi-twin chain records only count even lengths. So we are waiting for the first TWN10 block (which is the bi-twin of 4 links)

Yes that's why they are called origin, not prime. See my design paper or the bitcoin magazine article for the definition of prime chain origin.

Super cool. I guess the record list will get very long because the record will be constantly broken.
Even I didn't break the record, maybe I still get to name the prime chain I find?  ;D

I am thrilled to see the level of enthusiasms for primecoin in the mining market. I suspect maybe we already broke some world records but hadn't the time to fully research this. So I hope more of you can keep an eye on this and keep the record book updated  ;)

The Cunningham chain record book is presumably maintained by Dirk Augustin here:
http://users.cybercity.dk/~dsl522332/math/Cunningham_Chain_records.htm

The bi-twin chain record book is presumably maintained by Henri Lifchitz here:
http://www.primenumbers.net/Henri/fr-us/BiTwinRec.htm

Upon a quick examination I have found that 2CC09 is the first world record claimed by primecoin:


Block #2044 New World Record for 2CC09 (131 digits)
Block #5355 New World Record for 2CC09 (158 digits)


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 ;)

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>

If the validate shows 'ismine' as 'true' that means you own that address.

This is exciting even when I double check to confirm I am not the winner.
Only 3 days we made the record. Sunny is really innovative and contributing a lot to the community.
Bravo!

It's a php function gmp_prob_prime (http://www.php.net/manual/en/function.gmp-prob-prime.php) which is part of the GMP (GNU Multiple Precision) extension. It uses Miller-Rabin's probabilistic test to check if a number is a prime.

Is block 2616's TWN8 chain with origin length of 111 digits (http://primeblock.kicks-ass.net/block_crawler.php?block_hash=cf81181ef81e2078c1e51a86bca414ba897c751adf0aa82ff2b5747bbd516932) interesting?

edit: Realized that no it wouldn't sit in the top 20 of 'BiTwin Records two links'

Bi-twin chain records only count even lengths. So we are waiting for the first TWN10 block (which is the bi-twin of 4 links)

You tested the centers, you need to test the chain results. In Sunny's paper it describes how to get them, or here:

http://en.wikipedia.org/wiki/Cunningham_chain

You are quite right. However, the first probable prime still fails.
The positive result is:

does this mean it's not actually generating valid primes?

As I understand the primecoin paper, it accepts pseudoprimes for making a block..  as a true check of primality would take too long for nodes to verify.

Has it been confirmed that these are valid prime chains? If I'm not mistaken (please correct me if I am), primecoin only checks for probable primality.

You're absolutely right. I'm in the process of checking all these primes with GMP-ECPP (http://gmp-ecpp.sourceforge.net/). I'd be really surprised if any were composite (because "probable prime" means 1 in a zillion chance of being composite), but it can't hurt to check. BTW, if anyone knows a faster primality certificate generator, I'd love to hear about it.

My Python code :-)

This needs to be updated to include the Twin Prime record lengths. I wan't able to decipher the Twin Prime records website for lengths, but there's not much modification required.

The code will run through the entire block chain on the first run then save the results to a text file. Subsequent runs will simply check all blocks since the previous run.

Note this code uses ServiceProxy, which is available from the Bitcoin wiki.

Edit: The chain code comes out in hexadecimal, so a 10-length chain is 1CC0a, for instance.

Code:
from jsonrpc import ServiceProxy

import time, json

USER = '<user>'
PASS = '<pass>'
PORT = 9912


fname = 'worldrecords.txt'

# Searching for new world records

def main():
	ip = '127.0.0.1'
	addy = 'http://%s:%s@%s:%i' % (USER,PASS,ip,PORT)
	p = ServiceProxy(addy)
	
	# http://users.cybercity.dk/~dsl522332/math/Cunningham_Chain_records.htm

	records = {

		blk += 1

If I am not mistaken, Block 12344 contains a notable bi-twin chain.  The origin is 107 digits long and it is a chain of 3 links (i.e. 8 primes).  It is not a world record, but would be 4th on the list of chains of 3 links.  I was the miner of this block and would be willing to demonstrate ownership of the coins.

Edit:  It would appear that block 17302 also contains a (somewhat less) notable bi-twin chain.  It is only 97 digits long, but also contains 3 links.  As with the other, I am the miner and would be willing to show ownership.

You can verify you own an address with the signmessage command:
Code:
primecoind signmessage addresshere "Koooooj owns this address"
and posting the address, message, and signature.

(I think you could run that in the debug console too, just omit the primecoind part at the start. Or is there just a UI to this feature? I'm not using the QT client.)

(These aren't particularly large for prime numbers. They're big  for prime number chains.) Some mathematicians may find this data useful.

good point, however i disagree that they are "infinitely more valuable". XPM(prime) has scientific value(which in my mind is debatable, but then again i'm no mathematician) and sha and scrypt has security(proven until its broken) seems like an apples and oranges argument to me.

The value is in base 16. Change "int(chain[3:5])" to "int(chain[3:5], 16)".

according to the trolls in the cryptsy chatbox, primechains are only pseudo mathematics and have no use in the real world, so don't get your hopes up i guess. me i think that prime numbers serve some type of purpose. what it is? i have no idea

Which record is that supposed to be for?

Also, see this for the real way to verify you own an address:

If I am not mistaken, Block 12344 contains a notable bi-twin chain.  The origin is 107 digits long and it is a chain of 3 links (i.e. 8 primes).  It is not a world record, but would be 4th on the list of chains of 3 links.  I was the miner of this block and would be willing to demonstrate ownership of the coins.
You can verify you own an address with the signmessage command:
Code:
primecoind signmessage addresshere "Koooooj owns this address"
and posting the address, message, and signature.

(I think you could run that in the debug console too, just omit the primecoind part at the start. Or is there just a UI to this feature? I'm not using the QT client.)

Well you'd expect that coming from people who support other coins, as always.. when they don't understand or aren't invested in something they bash and troll it.
Anyways they are usefull for some mathematicians, I belive only a few use such huge primes, that's what I've found out a while ago..

I'm so sorry for all the inconveniences I have done with this matter... I don't know what happen to me today... I'm usually not so silly... perhaps the meal?  :-\

Well sign it something like "[real name] - [username] on btctalk".
So people can assign a real person to the record and we know who you are on here  ;)

The CC chains have even "real" world use as you can create "Auto-Recoverable and Auto-Certifiable Cryptosystems" with them. This are public key infrastructures with the capability of recovering the private key by authorities cooperating with the certification authority. In other words crypto-system which LE agencies are able to decrypt but not some other attacker. I´m sure every state would love if people would start using such systems :D
From a more mathematical stand point this data has also value as there are still many open questions in this area like e.g. if there are infinitely many chains of a given length and the distribution of such chains in the set of all primes. This data could be used for verifying conjectures in this area.

By the way Sunny, how do you have choosen the difficulty algorithm, did you used the Hardy–Littlewood conjecture?

These signed messages don't get sent out to the network... All you are doing is proving that you own the address. The message contents are irrelevant, it's just convenient to include your username in it. So no need to be concerned about your 1st and 2nd signed messages.

If I'm not mistaken, Block 28769 contains the new world record for BiTwin of four links (10 primes / TWN0a), 100 digits.

Also, the BiTwin primes listed on the records contain only even numbers of primes, yet our mining uncovers chains like TWN07, TWN09, etc. How are these defined? Do they count toward official records?

Odd numbered twin prime chains are defined as having only half of the final pair.  I doubt the record books would care about the final pair, since it's a prime and a composite, so TWN07 is really a TWN06 and TWN09 is just TWN08.  The odd numbered chains work just fine as a proof of work, though, and seem to behave nicely as far as difficulty is concerned.

Block 36946: 101 digits. Surpassed by Block 39211: 107 digits. Surpassed by Block 42915: 113 digits.

2CC11
Block 38425: 91 digits
Someone needs to definently keep track of these and try to get the names of people who got them. I mean having your name on a world record is something isn't it?  8)

THIS ^^

I just posted this idea in another thread, but I'm posting it again to reach more XPM miners.

I've started 'banking' single mined blocks in encrypted wallets with each block I find by making a back-up and creating a new wallet each time (where possible).

I figured that if / when someone happens to find a block with an exeptionally long chain, then at least it will be a mined block on a single wallet.

This could give the block a higher value in the future as the coins will also be unspent.

Primecoin is a Scientific Computing Cryptocurrency afterall.

I don't think those guys with 100 or 200 VPS were mining to get some sort of prime record :) I don't think they will go check their addresses, even if they still could :)

The real cash awards are for finding Mersenne primes (the longest of which is over 17 million digits long). Primecoin is not searching for these, if it were then blocks would likely be months or even years apart. Primecoin is dealing with much smaller digit numbers to keep transactions moving.

For those that do not understand the implications of primes on real world situations:

Its quite comical to think they are useless and don't tie to any benefit once you fully understand. The implications are yet out of our grasp much like parts of space research and particle physics. But the more patterns and links between primes are found, the closer we are to cracking the seamingly random nature of the numbers. Why does this matter? Many things in the natural world use primes - but why and how they know are not yet understood. So it has a close connection to understanding some of the natural laws of our world.

Not in debug.log. That output is from the Python program I pasted a couple posts back. The code should work cross-platform, since it's Python.

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

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.

Congrats glongsword, your block is 1st-equal with block 78915...

You can verify you own an address with the signmessage command:
Code:
primecoind signmessage AezMwyLP2hpT3yh3LDZkydqkpsrTg7Eyfk "glongsword owns this address - or whatever message you want"

If you're using primecoin-qt then go to Help > Debug window > Console and run:
Code:
signmessage AezMwyLP2hpT3yh3LDZkydqkpsrTg7Eyfk "glongsword owns this address - or whatever message you want"

Post the address, message, and resulting signature here and it's sufficient proof that you can claim discovery of the 2CC0a prime of 123 digits.

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.

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 like your avatar  :D

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 ;)

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? :P

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  ;D)

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.

Are you submitting these results to the relevant organization which track them?  Would be great publicity for primecoin.

As soon as I figure out how to show them properly I will.
I have no idea how to actually show the numbers themselves :)


My block crawler displays them:

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

If you want the source, you can download it here (https://apps.memopal.com/d/?8Q32GGKV). 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 (http://php.net/manual/en/book.gmp.php) 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!

There are some performance improvements in v0.1.2, those are already published in the repo. Although the built-in miner is not expected to be competitive against market offered solutions, I think those improvements would also be incorporated into some of the available miners soon.

The other feature of v0.1.2 is a new 'chainsperday' stat for getmininginfo. It is a better metric for tuning miner performance.

Jens has updated his world record list now Primecoin officially owns 3 world records 10-primes, 11-primes, 12-primes for simultaneous primes! Thanks Jens :)

Maybe whenever a new record is found the client can pop up a message in the sameway a new block is found. Maybe we can call primecoin CunninghamChain@Home

Didn't expect this to occur this fast, I was expecting by the end of the year.

Cheers!  :D

Terrific! Checked listprimerecords and it's not mine  :( or maybe it is my ypool block ?  :)
I did some investigating and there was only one person on Ypool that found a block around that time. The address didnt match their name so its not them. I think it was someone who was solomining that found the chain. I know from talking in ypools chat that someone has probably found 11 and 12 chains.

The new Cunningham chain of length 13 is very imressive!


I already updated the Cunningham chain record list.

http://users.cybercity.dk/~dsl522332/math/Cunningham_Chain_records.htm


And Jens also updated his list for Simultaneous prime records:

http://users.cybercity.dk/~dsl522332/math/simultprime.htm


Henri also updated his BiTwin record page end of August:

The Datacoin network has also produced several notable top prime chains. While there are no records, some chains make it to the top three. The difficulty is still below 10.

Yes, Datacoin does the same work. The risk of duplication is probably negligible.

For those interested, I've programmed a bot to screen the blockchain for new record breaking primechains. You can follow it on twitter https://twitter.com/OldEee_Miner (https://twitter.com/OldEee_Miner). Apart from record primes it also tweets about the price and it's own (really, really slow) mining efforts.

The first number is the length of the chain; it describes how many primes the chain consists of. It is conjectured that there are infinitely many chains of any length. The second symbol denotes the type of chain. 1CC and 2CC are Cunningham chains of different kinds, while TWN is a bi-twin chain. The following list of numbers tells how many digits the largest starting primes have.

CDN (Canadian Digital Notes) has nothing to do with prime numbers.

See http://galaxies.mygamesonline.org/digitalisassets.html

It has been around for years, since back when GRoUPcoin and DeVCoin were new.

In this context, CDN refers to CDNcoin (https://bitcointalk.org/index.php?topic=393190.0). An official currency symbol is not the only thing that coin is missing.

Now _this_ is a coin that actually _does_ something!

Out of the thousands of coins that have come since, I doubt any have had an equal impact on the world of scientific research. Of course, 999 of those devs were just looking to get rich by lying to the unsuspecting. Now we know better.

I just can't believe nobody was inspired by the fact that somebody once made a coin that was useful to society. They probably were, just not this year.

Anyone know how to find out if there have been any new prime number found lately?  Is there a way to check from the wallet?

You can use listtopprimes to find the top primes for each form which were found by Primecoin, e.g "listtopprimes 14 1CC" to get the largest Cunningham chains of first kind of length 14 (abbreviated as CC14f).

As I've just seen today, Primecoin broke the record for CC14f just two weeks ago. This is the first world record for Primecoin since more than 2 years.

2017-01-25: CC14f with 96 digits: 814204479584287721291003734102406590210007590854164398588152723240001514789312*47#-1

Update of my Cunningham chain record list will follow shortly.

Dirk

Did this coin die? Why? I feel like it's a hidden gem if someone decides to market it especially in mathematics departments around the world.

How often does XPM find a new prime number? Does it get longer to find each new prime number?

A new prime chain is found with each block (~1minute). Within a prime chain, each number is prime and is larger than the one before. Currently we're looking for chains with at least 10 consecutive primes. The first prime in the chain is guaranteed to be at least 256bits long - but could actually be much much bigger depending on the primorial and multiplier chosen. Miners don't tend to look for larger primes as the maths involved takes longer - hence mining is slower. 

This is a very intellectually challenging coin to write a good miner for - there are several conflicting aspects that directly influence mining speed and pretty much every design decision becomes a trade off :)
For example:
1. Mining with a large primorial increases the base prime probability at the cost of fundamentally larger numbers that are slower to verify and work with.
2. Mining with lots of primes increases the sieve accuracy and reduces the number of false positives that then get passed through to chain length determination, but using too many primes above a certain threshold removes so few candidates that its actually faster to deal with false positives!

This is one of the coolest coins out there yet no one really seems to be leading it's marketing anymore.  Is it still active?  It still trades so I wonder if anyone is mining it, and where are the best optimized miners for it?  Seems like some graduate school professor could take this thing over and make it last decades.
