Works for me, a new fresh insight might help!

I'm still piddling around with making a mining pool as time allows, I used up all my "free credits" for the vps route. But I have a small personal server that im using to toy with. My time is limited but I have a much better grasp on what might be needed to make a functional pool.

trnicely.net has gone offline ... I'm editing links for Dr Thomas Nicely records / website at https://gapcoin.club to:

- https://faculty.lynchburg.edu/~nicely/

...

- https://en.wikipedia.org/wiki/Talk:Prime_gap#Source_Site_Down

"Source Site Down

Thomas Ray Nicely died September 11, 2019.

His internet site (trnicely.net) stayed up through November, but is defunct now. That site was the main source for news about prime gaps.

Is anyone planning to take over the dissemination of prime gap results?

In particular, the files allgaps.dat and merits.zip need to be kept updated, perhaps quarterly, at least annually, and made available at least on an ftp internet site.

The main problem would be in the checking of new gaps. A modern fast multicore machine would probably be needed.

If someone does this then please add a date code to the filename, perhaps merit201.zip and algap201.dat for the first ones in the year 2020. That way someone would not accidentally overwrite older data.

If there is already another internet site with this information, then what is the URL?

The gapcoin.org domain is currently registered with Ascio Technologies, Inc. Denmark, a coincidence ?

Guess we will have to see what happens when the domain 'expires' end of May 2020.

...

Gapcoin has already made Math history! So much for the bitcointalk 'community' these days ...

Everyone (anyone?) OK with myself starting the new [ANN] thread ?

Block explorer renewed by gapcoin.club for additional months.

...

Any more exchanges want to list Gapcoin ?

A solid world record breaking altcoin since 2014 !

You can still mine in-wallet with CPU ! > setgenerate true

Development continues ... any more for any more ?

 

Nope. Gapcoin is most certainly very much alive. However, the OP most likely has very sadly passed away.

Gapcoin is an important Math based cryptocurency that actually broke and seemingly still holds the world record prime gap.

Prime gap's ...
- https://en.wikipedia.org/wiki/Prime_gap

"As of December 2017, the largest known merit value and first with merit over 40, as discovered by the Gapcoin network, is 41.93878373 with the 87-digit prime 2937032340680225901587237661044194634257090755748117620985887982178957288586767 28143227. The prime gap between it and the next prime is 8350."

We can break new records using Gapcoins existing proof-of-work. You can mine Gapcoin with your computers CPU in-wallet currently, just like you could with Bitcoin circa <2009-2010+ (for it to be worthwhile) ...

The Gapcoin project is maintained here: https://gapcoin.club

With growing community interest a new thread [ANN] is very likely indeed. Gapcoin is a genuinely amazing cryptocurrency project and has been ignored under the radar for to long.

...

P.S. Chatter is not off-topic and concerns Prime numbers / historical computing, as does Gapcoin.

Is this coin dead? Lots of off topic chatter and dead links on page 1/

Images from printed primes

Inspired by James McKee's Numberphile video and subsequent "Futility closet" post on the "Trinity Hall prime", physics researcher Gilles Esposito-Farèse discovered a prime number that, when printed, forms this image.



(more images on Gilles' page (ref above).

Elsewhere, it has been discovered that primes conspire amongst themselves: https://www.quantamagazine.org/mathematicians-discover-prime-conspiracy-20160313/

Happy New (Gregorian) Year.

Thanks for that one! What is this even supposed to mean?

Would you prefer that I switch off my Gapcoin nodes (including Tor nodes) + the gapcoin.club website, that I cease paying for the only block explorer and stop trying to get Gapcoin listed on new crypto exchanges etc., ...

... or perhaps are you just trolling this thread for arguably the most brilliant math coin to grace bitcointalk ... where the developers seemingly passed away in tragic circumstances.

@BitcoinFX Nobody cares what you are up to. The coin and its honeycombed structure of interlaced networks is marching ahead at a steady pace which will accelerate to gallop before Chinese new year. Times are changing, you are either with us or behind us. The stink is hovering in the air while the air is hovering in the space as an illustration of the universal law of embedment which also gives some philosophical pretext to the possibility of the perpetual machines of the first kind.


What is TVT? GAP has no ties to it.

Is TVT a shitcoin right now ? I mean, it will be the clash of the titans between TVT, Flappycoin, Dojecoin and Tittiecoin ? 1TVT = 1 tittoshi in aprox 2 months ?guys can anyone confirm that TVT does not use a mixer to create anon transactions. if so, then TVT is the best anon out there

Thanks for all your efforts, input and hard work on this one Graham (and community !?!) ...

A belated Happy New Year !

I have to migrate some of the servers to new LTS builds and I will be updating the https://gapcoin.club website with new info.

Anyone for a new windows release with updated SSL etc., ?

Getting very bored of 'slow play time', lets build this community and start to get listed on some additional exchanges etc.,

Again, Gapcoin is going nowhere, except for the record books !

No such thing as an economic point of no return.

 

P.S. I'm continuing to renew the block explorer, again.

Cheers!

We don't even live in the True 64 bit age yet.  Lots of SLOW PLAY TIME!

Supercomputers will not reach that memory 16 Exabyte capacity in the nearer future, but since they don't have a shared memory space then 128-bit won't be that important.



I know a bunch of navy people who would be willing to classify the Zumwalt-class destroyer as a Battleship. The consensus seems to be that it's called a Destroyer only because BB's are presently the butt of the joke about following the old paradigm too long, when everyone should have been building aircraft carriers instead.

It's only 15k tons, which is a far cry from the Iowa class Battleship, but it's still heavier than many of the Pre-DN battleships. It's certainly not a destroyer, because DD's are traditionally used for killing small ships, submarines and aircraft, each of them a task that the Zumwalt does not do. Instead, Zumwalt is meant for engaging surface and ground targets with missiles and guns. It only has 2 guns, but they are water-cooled, fully automated and have fire rates good enough that it can land as many projectiles per minute on the target as the Iowa. The projectiles themselves are, of course, much lighter and guided.




Today's 64-bit Intel CPUs can only address 48-bit memory btw, cost savings because nobody will have that much memory in one machine for the foreseeable future. more $$ for intel and AMD.




In a sense it's both 48-bit and 64-bit at the same time. The actual addresses are 64-bit, but the specification of AMD64 only allows the first 48 bits to be used; bits 48-63 are just a copy of bit 47.



If the memory controller was implemented as 64 bit instead of 48 bit, there would be no performance difference. but using 48 bit math instead of 64-bit, saves you transistors.



The Ext4 file system physically limits the file block count to 48 bits.



The minimal implementation of the x86-64 architecture provides 48-bit addressing encoded into 64 bits; future versions of the architecture can expand this without breaking properly written applications.


The media access control address (MAC address) of a computer uses a 48-bit address space. This can be changed to 64-bit addressing.



A 48-bit memory address can directly address 256 Terabytes. A processor with 64-bit memory addresses can directly access 16 Exabytes.



In principle, a 64-bit microprocessor can address 16 Exabytes of memory. However, not all instruction sets, and not all processors implementing those instruction sets, support a full 64-bit virtual or physical address space.


The x86-64 architecture (as of 2016) allows 48 bits for virtual memory and, for any given processor, up to 52 bits for physical memory. These limits allow memory sizes of 256 Terabytes. A PC cannot currently contain 256 Terabytes of memory (due to the physical size of the memory chips), but AMD envisioned large servers, shared memory clusters, and other uses of physical address space that might approach this in the foreseeable future. Thus the 52-bit physical address provides ample room for expansion while not incurring the cost of implementing full 64-bit physical addresses.



The free software used to implement RISC-V architecture is defined for 32, 64 and 128 bits of integer data width.

ZFS is a 128-bit file system.

https://en.wikipedia.org/wiki/ZFS

https://github.com/zfsonlinux/zfs


One important feature of making a 128 Bit ASIC with high amounts of RAM, is that 1. We can break out the limits of Memory that way using Yitang Zhang algo.  2. 64 bit and 32 bit virus programs cannot be run on 128 bit ASIC machines.

Er, "it requires a multiple precision arithmetic library that can handle 128 bit numbers"  - are you unaware of the difference?

Perhaps a quote from the Prime Gap Searches group of the Mersenne forum will make it clear: "the crucial part would be to find efficient 128 bit replacements for mulmod / powmod. And extending the segmented sieve (bit buckets) to more than 64 bits might also be tricky".

To spare myself further apparently futile explanation, I'll consider the matter closed unless/until you can come up with some concrete, detailed suggestions for changing the mpz functions in PoWUtils.cpp and Sieve.cpp sources so they are able to perform 128-bit arithmetic.

Cheers

That there is no development is not a surprise as my timeline for development should have signaled.  

However the Boost Library does.

"As pointed out by other answer, C++ standard does not require 128 bit integer to be available, nor to be typedefed as uint128_t even if present. If your compiler/architecture does not support 128 bit integers and you need them, you could use boost to emulate them:"

http://www.boost.org/doc/libs/1_58_0/libs/multiprecision/doc/html/boost_multiprecision/tut/ints/cpp_int.html

"I think that the boost library will automatically use the native type if available"


It really doesn't figure that learning would ever be considered a "Waste of Time".  However developing a purposely retarded system to slow play ignorant people is not even remotely honest nor a good foundation.  

You seem to have gotten carried away more than usual, that doesn't make any sense at all - not even to you, I'd guess.

The show-stopping obstacle to your suggestion of using 128 bits is that it requires a multiple precision arithmetic library that can handle 128 bit numbers - which doesn't yet exist. Until it does, your suggestion is completely impractical and you're wasting your and everyone else's time in publicly pushing for it.

Cheers

P.S. SHA512 keys have been available in  Bitcoin Core since the release of 0.13 with the migration to hierarchical deterministic keys.

Hi Mr. Higgins,

It seems Sha512 supports up to width of 128 bit numbers. 

https://en.bitcoinwiki.org/wiki/File:SHA-512.jpg

https://stackoverflow.com/questions/34588650/uint128-t-does-not-name-a-type


It would seems the this has all become a winner take all scenario. 

If any work is done it might as well only be done ONCE.  It would likely never need to be changed using int128_t, uint128_t.


The Government can still use the other software backdoors they create while the Math hardware can carry on regardless. 

Probably any development would need to go through the CIA meetings like Bitcoin did early on.  But since Power is "Shifting" maybe we can get a "Devs" to escape to Iran to develop the system for the space port there.  Russia has good protections as well, but it is getting crowded already with high profile runners. 

Plus nothing spells trustworthiness more than a seal of approval from the Iranian government.

Otherwise it is looking like 100-200 years before the west slow plays their dead hand to extract things from everyone stuck using their western US CIA approved 32 bit encryption systems.  But at least we will all be Austic, Gender Fluid, and on Epstein Humpty Dumpty watch list. 

I'm pretty much done with setting up the support infrastructure for the mersenne forum prime search group's pick-up of the maintenance and publishing of Dr Tom Nicely's list of first known occurrence prime gaps.
