Dang, someone wants some gaps !
Great support, thanks for that.

Really profitable to mine these days.
WheRe ArE tHe MiNeRs !?  Full throttle guys Smiley

Are there still old members ? I'm curious.

Probably not this one.

Every "John Frey" on earth is working in Maths, Computer Science, Dev, Algos [...] and is a candidate. Cheesy

I assert that John Allen Frey was the original developer of Gapcoin
Your assertion may has been proven wrong since j0nn9 (Jonny Frey) has been active on bitcointalk on March 23, 2018! Also he (or his script) has updated http://gapcoin.org/primegaps-length.php on September 10, 2019!

I have to agree. BitcoinFX’ assertion falls in the face of considerable evidence to the contrary to what is, after all, a very tenuous string match.

In addition to the contradictory evidence already identified by PrimeObsession and previous honest assessment :

1. The soubriquet “j0nn9” was in use in April 2014 by someone calling themselves “Jonny”, working in the crypto arena “Building MaidSafe on ArchLinux”, bylined “Gepostet vor 30th April 2014 von j0nn9”

2. The GAP donation address listed on gapcoin.org has seen activity in 2019.

3. The gapcoin.org website page for “Gapcoin’s highest found merits” carries the headline date “as of 2020 March 31”.

4. The DNS registration for gapcoin.org was renewed on 2020-04-30. The server hosting gapcoin.org is now located in Denmark, according to the DNS resolution, previously the DNS resolved to a German location.

5. The posts, code documentation and comments testify to someone for whom English is a second language. (No implications other than that, j0nn9’s English is a damn sight better than my basically non-existent German.)

6. “Jonny Frey” is not an unknown name in Germany - an example

There are also other Frey in USA that are more likely to be him.

This is my mininginfo. Program changes some parameters after some running times. currentblocksize, currentblocktx, pooledtx.
All quite normal, blocksize will vary (to a maximum) with the number of transactions included in the current block and the poledtx reflects the txs in the mempool waiting to be included.

Crystal clear and Good logic, nothing to add.

Just see this, fyi. There are some 'Tipping points' with shifts and compute time/difficulty.
For shifts <=64, your hashrate is safe. Big drop @shift 65. (~-25%)

The Gapcoin community thanks you. Smiley

PS:
To write gpu code for a newer GPU is much harder to do.
Indeed.
A CUDA version of the required files "already exists" in another github repo. Need to implement them into gapminer.
The most important change required for the miners will be regarding Getblocktemplate, at some point.
Optimizations are another game, but definetly possible, I think.

Nice !  Smiley

Indeed, to calculate a gap with merit > 28 is difficult. 'Logarithmically' more difficult. (or you need some kind of 'Luck')
And, in shift 33, you will find gaps, but you'll not hardly improve the existing records* of these Prime Gaps. Kind of a waste. (But not useless, Low shift = High hashrate = Higher network hashrate = Higher Difficulty = Higher minimum merit for gaps (and higher rewards for everyone))
* cf. Prime Gap List

For example:

Your record (block) is :
5740,C??,28.677447,Gapcoin,16-04-2021,87,845673412451...
and the current record for the Gap 5740 is :
5740,0,C?C,Gapcoin,2019,29.5399,85,2451301016220...

401091+ blocks were mined at shift 32 and around, so the gaps around have already been improved again and again, the chances of improving them are reduced. (With the same hardware and miner)
Of course, it's still possible! :
6514,C??,29.378649,Gapcoin,12-04-2021,97,1968898235788..
6594,C??,29.765900,Gapcoin,08-04-2021,97,16168707142690..

See the Discord invite in my last post.

Don't hesitate to try to mine using the CRT, to find records like this (better than current records):
10696,C??,30.172495,Gapcoin,13-04-2021,154,902067920..
23730,C??,26.761068,Gapcoin,16-04-2021,386,127206495673873...
23832,C??,29.046292,Gapcoin,02-04-2021,357,214488270708355..
24232,C??,27.320439,Gapcoin,14-04-2021,386,15836400496139...

Mining in the upper shifts increase the compute time and reduces the shares sent to the pool (and therefore the rewards), so if you want to get a few more gaps, it's better to mine in solo when using the CRT. (With a decent CPU, 8+ Cores). But current records have weaker merits, in general.
So, to compensate, I would be happy to compensate anyone who posts new records here, or on discord. (with a gap address)
Let's randomly say 50 Gaps
per record. (for the first 2000 Cheesy)

PS: GPUs are stuck (hardcoded) on Shift 32 (for now). Only 'gapminer-cpu' can vary shifts. And only 'gapminer-cpu' using CRT can go (efficiently) above shift (~)128.
For the CRT Miner, it's unclear but, tests/s are probably your 'hashrate'. Not the PPS. (Need to be proven)


Good Luck & Have Fun.
Wizz_^

Thanks for your respond.

I have been using other shifts but decided to try shift 33 because according to the published statistics there were no work done on shift 33. It's also low enough numbers to find a decent amount of gaps per day.

I have tried the CRT miner but decided not to use it. It's not about it's lower reward but the fact that it puts a heavy load on my CPU. I don't have a graphic card for this code. So until then  I will put the effort at lower shifts that have not been searched and high enough to be possible to find a new record.

To me the hardcoded shift 32 is easy to change. To write gpu code for a newer GPU is much harder to do.

Have a nice day.

Note: All the published pointers to the in-development 0.16.3 client are to my own repository
Currently, my plan is to make the gapcoin-project 0.16.3 client a minimalist upgrade, preserving only what's absolutely necessary for a Gapcoin port of Bitcoin 0.16.3 (i.e. the obvious cosmetic changes and Gapcoin-specific chain parameter values, some necessary changes to the block structure in order to carry the prime gap data, the replacement of the proof-of-work code, the difficulty modifier code and the reward code). This will make things usefully simpler for anyone else who might want to work on developing the core Gapcoin 0.16.3 client.

As for my own enhancements to the 0.16.3 client, I will offer a separate “de luxe” client with source code and binaries available from my own repository.

I feel this approach better reflects the decentralised nature of this domain - as I observe elsewhere, there is no “official” this nor any “official” that.

Cheers

Hi
I like your work. You put in a lot of hours into this projekt and I can see that. I have tried to to solve some blocks but I think I have only found so far 12 gaps with merit 28. Still hoping to find bigger merits.I don't have a AMD card so I use my CPU. The last one I found was this one today.

There are always too few miners in the high shifts.
Absolutely no one wants to test ?  Roll Eyes

It's always easy not to have any proof, no matter how simple they are.

And then claimed his intention to destroy the 16.3 Gapcoin Repository history?Huh?

Cause idiots obviously don't understand the "Alpha/Beta" &  "Pre Release" part.
There is no script, backdoor or trojan, as i know, you're totally crazy.

Transactions from 0.9>0.16 or 0.16>0.9 works fine for me.
0.9 works fine for me.
0.16 works fine for me.
Gapcoin works fine for me. If i see something, i point it out.

No problem, except your harassment to the project here.
(See the diff between an 'incident' and a 'problem', cf. ITIL: Incident management vs Problem management)

Mr. Higgins did the GH Primegap List Project web site, working with S.Troisi and the Mersenne Forum members.
Mr. Higgins did the GH Gapcoin Community-led Project web site.
Mr. Higgins did the Core client.
Mr. Higgins submit all gaps records !
Mr. Higgins is working on the amazing ACME.
Mr. Higgins is interested to help with the nvidia miner.

It was the Gapcoin's community that asked him for his help. And he's f*****g clear on every subject !

But I produce some records, on a regular basis.

Yes for the Record I am all for a Hard Fork of Higgins' Repo.


It appears Mr. Higgins has a remote exploit inside the github source code.  As 3 computers I left copies of the Gapcoin-Core Compiled binaries, however the wallet.dat from when I used it now says corrupted file and when I delete that file to start with a 0 Zero Wallet Balance the Exploit is not there!

Either the Exploit is only triggered when someone has Coins in their wallet to a certain threshold.

This makes perfect sense to obfuscate any one target who Higgins' has as this Account Name!

Any Moderator would run the Zero Wallet Balance Binaries from source code and it would not trigger!

I mined with the wallets before ever trying to spend balances and only noticed after Modualia reported the bug.


I however deleted the wallet compiled from source code which had the actual evidence, as I thought it is surely in the Source Code I have on a another computer!

You can decide not to believe me but I am honest.  I was going to take screenshots.  But Prime Obssesion showed the transactions and Modualia reported it.



The Script is built into the NOTARY Field

The script auto generates inside the NOTARY Field.

The only reason I can think of that it would not be in all the source code I downloaded at the same time is that Mr. Higgins is operating Remote Beacons inside his code set to trigger at Gapcoins being present at a certain threshold to trigger!

I suppose you are super busy erasing the 16.3 Repository like you just said you were gonna do!

Which means according YOU

that your going to launch a Gapcoin Version 20/21 wallet which requires a hard fork in which you want to delete the history of your script that steals/loses coins from 16.3???


Honestly what kind of a moron would not test the send function like you did?HuhHuh

And than not even change the Source Code after almost 1 month?

I have nothing to defend myself against except your obnoxious attitude which is designed to repulse newbies so you can Hard fork Gapcoin using your Cronies!  Giving you total control of the Blockchain!  

I WILL NEVER SUPPORT SUCH A THING!!!!!!

You have literally been here over 3 years or so and not developed jack shit except your recently defunct 16.3 Wallet that had a FATAL FLAW?HuhHuh??

What script? 

Please do point out this "script"  if you say there is a stealing script in there you must be able to point out this script right?

I doubt BitcoinFX or gjhiggins have any bad intentions nor would they release something that would steal users funds.

Accusations without solid proof are a big no no.

Sounds good Mr. Higgins,

Have you chosen a NAME for your Hard-Fork?Huh

I don't think the exchanges will allow the same ticker trader, and you should launch a New Thread ANN your Hard-Fork so you don't have to be an asshole to any new people here.  I promise I won't ever bother you on Discord.  If you think it's me, I promise you it's not.

I look forward to dumping your HardFork on the Exchange!!!!!
