It will be 4-6 more years before much more interest........don't worry about that..............try to build as tough and hard Shifts and Sifts while difficulty is low............

AMD Ryzen extra cores is perfect with 16 GB MINIMUM of Memory (Ram) and or AMD Threadripper

[gjhiggins]

Regarding a dev, it would be great to get gjhiggins, he has added a lot of value to slimcoin even if not yet reflected at exchange.

@gjhiggins is currently unable to assist with Gapcoin development due to other time constraints.

Thanks for the kind words, PTG. I've been able to make some headway since then and am now in a position to lend a hand on the technical side but, as with BitcoinFX, there are limits to what I can undertake both in terms of technical skills and allocatable time. I can start by taking a look at the options for “moving forward”.

This post is really just an initial communication of interest and a delayed positive reponse to BFX' enquiry, I haven't yet had time to go through the code and abstract out the key differences that distinguish the Gapcoin codebase from its cloneparent but that is usually my first port of call when first building an understanding of the coin's functioning.

Completely independently, I can create an ACME adaptation for Gapcoin (each adaptation is in its own branch). ACME is a cheap'n'cheerful means of adding a fair amount of persistent value as just a Python web app that presents metadata obtained by i) the coin's JSON RPC API and ii) a SPARQL endpoint.

The wallet keeps an index of tx->address but not an index of address->tx, that functionality must be created elsewhere and in pursuit of that, ACME maps the blockchain to RDF and uses SPARQL (via a Fuseki endpoint) to obtain and present metadata which is not otherwise obtainable from the coins's RPC API.

The ACME web app itself can be (fairly trivially) extended to present additional metadata seen as pertinent to the coin's functioning. F'rinstance, I added a page for Datacoin, re-presenting the results of the listtopprimes RPC call ...

http://tessier.bel-epa.com:5059/main/chain/

In Slimcoin's case, I was able to cherry-pick a few commits from a more developed clonesibling codebase and enable OP_RETURN tx as standard, opening up an opportunity to use the data field to carry a few dozen bytes of metadata, with all the possibilities that brings. As the “wallet” is basically a transaction explorer scoped to the owner's addresses, it's a straightforward task to add a couple of supporting GUI units: a  data entry field for creating “inscriptions” containing metadata (currently limited to the wallet's “default” address) and a scrolling list of all the user's txs that have non-null OP_RETURN values (i.e. all the user's “inscriptions”).

I haven't even started to read through the entire up-thread history, so I'm not yet in a position to offer any comments let alone answer technical questions about the codebase.

Cheers

Graham

Thank you @gjhiggins, always interesting work and contributions! PM sent.

Also found myself with even less time to contribute to getting gapcoin really moving again, however quite a few good developers and math folks are now becoming increasingly interested in this project. I will be moving the set (tentative) milestones forward.

Gapcoin has remained a Math project first and crypto-currency second of course. Having a functional meta data explorer for prime gap records will be most excellent indeed!

Mr. Graham  thanks for your interest in the G.A.P. project we need every team member we can get.  Hopefully you could help commit changes on github? 

I uploaded the correct steps to github under issues which should help you build the Gap system under Ubuntu type systems to avoid starting a new thread which has been under discusion due to my lack of usage of github.  But I find it simple enough.  It took me a while to figure out how to login to Bitcointalk here with the new captcha safely.

I use Trisquel OS to build gap wallets.  I don't know what type OS you use, but debian should work, I have tried many OS outside of windows but not much success outside of Trisquel OS. 

Building the wallet would be the first step I imagine.

[PeterTheGrape]

Website looks great.

Can someone explain what these transactions are doing?  Why do they generate such large gap amounts.  Is that address really paying 18-30 Gap just in transaction fees?

There is already a new wallet /Satoshi:0.9.5/ (Node List for /Satoshi:0.9.5/ - 88.98.87.243) ?

Where is the download from it?

Steady on, I'm still putting it through its paces, I haven't even addressed the test suite yet, nor is there anything other than a Linux Mint build atm, so it's a bit experimental. The work area is: https://github.com/gjhiggins/gapcoin

Good work, go on giving the news.

I will try to build a gapcoin node from your repository Mr. Higgins.  

Could you happen to incorporate the Unlimited Add Nodes into Gapcoin by default?  

Github for Unlimited Add Nodes

https://github.com/bitcoin/bitcoin/pull/9319

If we could get most miners using dual stack .onion/ipv4 mining we would be much better off than relying on ssl for tcp connections.  

For Dual Stack locate the .gapcoin folder using the Ctrl H button on your home folder to reveal the hidden folders.  open .gapcoin if you have already started gapcoin after compiling the software with github.  

create a file named gapcoin.conf and add this config terms to it

proxy=127.0.0.1:9150
bind=127.0.0.1
onion=127.0.0.1:9150
listen=1
discover=1


TORRC CONFIG TERMS

Here is the example to add to your TorBrowserBundle Torrc file assuming it is located on your desktop and using linux mint or ubuntu or trisquel os.  

Note this is only for the Alpha Build TBB which supports the new V3 Onion Services with 256 bit keys.  

HiddenServiceDir /home/YOUR_COMPUTER_NAME_HERE/Desktop/tor-browser_en-US/Browser/TorBrowser/Data/Tor/hsv3
HiddenServiceVersion 3
HiddenServicePort 31469 127.0.0.1:31469



GAPCOIN DOES SUPPORT THE VERSION 3 ONION SERVICES

I managed to connect two computers using the Onion V3 services..............


Pick 2-4 addnodes to put at the top of your add node list in gapcoin.conf than add regular nodes

addnode=jcs5iofila6pj44tvjlhtxfhzgc6pagx5xinij7kiow5poyhjmnswdad.onion

addnode=upb7qiiww7bbou7mrmufwqfyxahy2fyo7odhmpixlwyjsagef3k7dcid.onion

This is exactly what your gapcoin.conf should be to mine using Gapcoins ONION ROUTING VERSION 3 SERVICES and hopefully we can have the "Unlimited AddNodes
 to Gapcoin so we can just throw as many nodes on here in any order and have a TRUE Decentralized Prime G.A.P. supercomputer with every worker working together and sync with each other.  (INDEPEDENT OF COUNTRIES ISP BLOCKING) If we could connect 100 or 1000 or better 10,000 .onion miners together it would simplify a lot of the coding work to protect G.A.P. network from attacks.  I will add 8 to start......................

Anyone willing to share set up for cpu miner? Is it better cpu or gpu mining?

[PeterTheGrape]

Can someone explain what these transactions are doing?  Why do they generate such large gap amounts.  Is that address really paying 18-30 Gap just in transaction fees?

https://chainz.cryptoid.info/gap/block.dws?656418.htm

https://chainz.cryptoid.info/gap/block.dws?656417.htm

My guess would have been that it's somebody that mined a lot of blocks over a period of time and then is sending their mined coins into a sort of cold wallet? Is there anything which would contradict that?

As for the fees, isn't that something the sender can set voluntarily?

It's not really that much and maybe the person is used to having to use fees to push a transaction with other coins, so they just paid a little extra without calculating? Or maybe because there are so many imputs it has a lot of kb?

From the debug log...............................looks like it is consistently improving, not sure what log2_work translate to only thing I can think of is Merit, but that can't be right because their would be more eyes looking at this.


To build the wallet you need debian os/ubuntu os/trisquel os/ mint os

distrowatch.org

https://github.com/gapcoin/gapcoin

Check the issues tab and try to compile the wallet

CPU mining is setgenerate true in the debug console


GJHiggens has a repository fork of Gapcoin, but it does not compile for me.  It does not update the modules after cloned.

You get paid to solve math problems.

For example, mersenne.org is a huge project where people spend tons of computing power for no obvious monetary gain (although there's a prize for discovering new prime numbers). Here, you get smaller rewards for every block solved, which involve other prime-related problems. To me, it's better use of CPU power than mersenne.org; both projects do interesting math, but Gapcoin solves more practical problems as a cryptocurrency.

You should note that very few cryptocurrencies do any kind of useful work with their block verification. Some of those rely on central servers for work distribution, which breaks the core principles of cryptocurrencies. Gapcoin is one of the few genuine cryptocurrencies that do science on the side (along with Primecoin and Riecoin -- are there any others?).

The speculators, those of us in coins now to avoid homelessness, pay for meds etc, are bloodthirsty and want profit.

When the mainstream hits though and people want a currency, they will want something that feeds the future, instead of draining it like fiat.

Primes, and prime gaps etc, paint a natural picture of *some unknown pattern*. We don't know what it is nor what its meaning will be, but there is no doubt that at some point in the future somebody who has information we don't have will look at the picture painted by primes etc and be glad that not everybody threw their electricity into the garbage with trash like bitcoin.

Interesting item posted to Hacker News, a paper published at October's Fields Medal Symposium in Toronto: A Schr¨odinger Equation for Solving the Riemann Hypothesis (PDF). The approach is mentioned in the wikipedia entry:

The calculations in Odlyzko (1987) show that the zeros of the zeta function behave very much like the eigenvalues of a random Hermitian matrix, suggesting that they are the eigenvalues of some self-adjoint operator, which would imply the Riemann hypothesis. However all attempts to find such an operator have failed.
