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  Wink

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 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>

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/ (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",
    "primechain" : "TWN09.b4fd9b",
    "primeorigin" : "1379977696373299686489657264795932186988807519791671031116918283191809429649078965671417820492149886465837951201350875440",

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)

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




This is great. Pretty incredible that records have been found 2 days into this thing...

Bitcoin is the first monetary system to credibly offer perfect information to all economic participants.
But Bitcointalk & /r/bitcoin are heavily censored. bitco.in/forum, forum.bitcoin.com, and /r/btc are open.

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?  Grin

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  Wink

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 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>

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!

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

You are quite right. However, the first probable prime still fails.

Woot! Not sure it's me, I sent some stuff I mined on windows to my linux wallet and then destroyed the windows wallet Tongue

Anyway, very cool Cheesy

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:
Code:

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

Both fail on #9 in my Block Crawler:

Block 5355

Of course that is dependent of my code for generating the chain being correct. Wink

It's a php function gmp_prob_prime 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 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)

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.

It looks like block 1592 has enough digits to take second place on the CC9, 1st kind.

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 = {
'1CC06':633,
'2CC06':475,
'1CC07':356,
'2CC07':251,

'2CC0f':32,
}

data = json.load(f)
except:
pass

blk = 1

if 'block' in data:
blk = data['block']

if 'records' in data:
records = data['records']

if 'primecoin' in data:
primecoin = data['primecoin']

info = p.getinfo()
height = info['blocks']

while blk <= height:
hsh = p.getblockhash(blk)
block = p.getblock(hsh)

chain = block['primechain'].split('.')[0]
chainlength = int(chain[3:5],16)
origin = block['primeorigin']
digits = len(origin)

if chain in records:
if digits > records[chain]:
print('New World Record!\n Block %i, Chain %s, %i digits (previously %i digits)\n' %
(blk, chain, digits, records[chain]))
records[chain] = digits
primecoin[chain] = digits
else:
if chain not in primecoin:
primecoin[chain] = digits

}

with open(fname, 'w') as f:

print('\n\nCurrent Records')
for chain in records:
print(' %s: %4i' % (chain, records[chain]))

print('\n\nPrimecoin Records')
for chain in primecoin:
print(' %s: %4i' % (chain, primecoin[chain]))

We found our first length-10 chain at block 17937, type 1CC0a, 86 digits. Then we bested it at Block 21362, 96 digits.

World record is 99 digits, but both of these chains are good enough to knock out the existing 2nd and 3rd place chains on the books:

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. That's already infinitely more valuable than the results of bitcoin's sha256 / litecoin's scrypt random proof-of-work statements outside of the context of the currency.

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.

Primecoin's has both.

I find it a bit disappointing that for all of the extreme amounts of computational power that goes into Bitcoin's blockchain, all we get is a verification of the latest block. There's no interesting analysis possible of the proof-of-work statements. Primecoin at least doubles as an enormously huge chain of mildly interesting computations.

quick, lets make UFO coin. every signal decrypted and processed is a block. first person who decrypts it a processes is rewarded the block. now we have another scientific coin. see where i'm going with this? you know, at first i was being facetious but you just might have sold me. maybe scientific computations offered by prime and any future coins like it could offer a pseudo-backing for the currency, much in the way that physical gold and silver once backed physical paper money

I think I got the right blocks and signed correctly; my local QT client returns true upon verification requests.
All of that verifies for me.

Primecoin's has both.

I find it a bit disappointing that for all of the extreme amounts of computational power that goes into Bitcoin's blockchain, all we get is a verification of the latest block. There's no interesting analysis possible of the proof-of-work statements. Primecoin at least doubles as an enormously huge chain of mildly interesting computations.

quick, lets make UFO coin. every signal decrypted and processed is a block. first person who decrypts it a processes is rewarded the block. now we have another scientific coin. see where i'm going with this? you know, at first i was being facetious but you just might have sold me. maybe scientific computations offered by prime and any future coins like it could offer a pseudo-backing for the currency, much in the way that physical gold and silver once backed physical paper money
Doing analysis of external datasets would be a bit difficult to accomplish in a decentralized cryptocurrency, and the work has to be extremely quick to verify that it's correct, so many types of computations are out of reach sadly.

Clark seems to be on his game when it comes to prime chains. For now we take his word. i'm sure he will be here with proof sooner or later.

If you run "primecoind getblockhash 25180" and then "primecoind getblock hash", then you can see it yourself.

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..

Yeah...

I though that after send my second message, so I sent a third message with my real name (I don't know if I have to put this message in this post as well)...

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?  Undecided

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  Wink

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 Cheesy
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?

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.

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?  Cool

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.

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.

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.

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

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 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

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.

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

Hello,
I have updated my Cunningham chain record list:

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

Congratulations to all who found new records!

Please send me a PM if you want to have your real name on the record list. First of all you of course need to confirm that you really found the record like it's done in this thread.

yea shouldn't someone be tracking this so that an article can get published some day when some new prime is discovered?

i would do it but i don't even understand the mathematics behind this... just happen to get a few xpm because it sounds interesting  Tongue

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:

I updated the Cunningham chain record list three days ago:

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

Again Primecoin improved the records for Cunningham chains of length 10 and 12.

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.

So Datacoin is also helping with those mathematics? I was asking myself about that because it is a fork it may not help with that work...

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

A TWN of length 13 has been found : http://primecoin.21stcenturymoneytalk.org/index.php?block_height=340499 origin of 105 digits ! That is one to put in the record books.

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. Apart from record primes it also tweets about the price and it's own (really, really slow) mining efforts.

Thanks . I just got to know from the page that even for a 13-chain the difficulty is still 10.

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.

Primecoin has found a new record 2CC of length 13 (block 375981). Ironically, it has exactly as many digits as the previous record (block 159217). I have updated the table to reflect the progress of the coins.

Code:

           XPM    DTC    BEK    CDN

 6  1CC    --     --     89     99
 6  2CC    134    90     91     96

Congrats for the first Cunningham chain of length 13 with more than 100 digits!

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. 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.

Regards,
Dirk
