Dr Thomas Nicely



I'm saddened to learn that Dr Thomas Nicely died Wednesday, September 11, 2019, as a result of injuries sustained in a recent car accident.

I'm working my way through his website, saving the content for curation purposes (but I imagine that the internet archive has it all safely stashed) intending to explore the possibility of establishing the Gapcoin community as de facto collective curators of prime gap records.

Historically, the bounty for translations was 25 GAP but that seems a little paltry these days. If you wish to post a Gapcoin address, I will send you 50 GAP.

Cheers

Graham

fwiw Dept:

As part of my attempts to resolve the apparent contradiction between the assertions about how primes are filtered in Gapcoin [1] and how that's done in the actual PoWCore source code, I scraped j0nn9's posts to this, the Gapcoin thread, sorted them into ascending order and rendered the result as a standalone page of HTML that I have published as a github gist which can be saved and opened in a browser:

https://gist.github.com/gjhiggins/75073257527aa6304b3913688f2b46c8

[1] “Gapcoin follows Riecoin's way and uses enough Miller-Rabin tests with random bases to avoid composite numbers being accepted as Prove of Work.”

Added:
In an effort after greater clarity, I distilled and categorised the posts, rendering them as a page of HTML that uses jquery and semantic-ui to present the posts in a series of accordion (drop-down) sections for ease of consumption: https://gist.github.com/gjhiggins/dded25cb7a6d46531a3c8bd52074bde4

BTW, I found out what [1] was about and annotated my own copy of Gapcoin-PoWCore's PoW.cpp (https://github.com/gapcoin/Gapcoin-PoWCore/blob/06ac3fea780997232e9d5c78bfaf34d72e1b4e13/src/PoW.cpp#L130) with the docs of the gmplib functions mpz_probab_prime_p and mpz_nextprime:

(In case anyone other than me is interested.)

An interesting project, I translated it into Russian.
https://bitcointalksearch.org/topic/ann-gap-gapcoin-prime-gap-search-5198025

Choose a gapcoin address-privkey pair from the list, fire up a gapcoin client, wait for it to fully sync, open the client debug window, select the "console" tab and enter:


 You'll need to wait for quite some time while the client rescans the blockchain. When it's finished, you should have whatever balance is shown by the chainz explorer for the chosen gapcoin address. Now send those coins to another address in your wallet before someone else imports that privkey and sends the coins to an address they control.

It's a literal example of a "free for all", aka "airdrop".

Hi, i'd like to test this please.
How does one go about it?

Thanks
J

The 5-yr old noncepool fork may not be the best choice - the repos owner notes: "This fork is still in development. Many features may be broken."

In principle, the gapcoin-hash-python library will probably work with a modern version of stratum. Collectively, we might be better served by taking ahmedbodi's more recently-maintained fork and applying the  noncepool submitblock change. If that proves beyond our reach, ahmed's professional expertise is available for hire.

Cheers

Graham

This post will self-destruct on 1st Jan. 2020 or soon after the coins are moved to new gapcoin addresses.

Awesome, I didnt look at it from all those perspectives. Great advice - I really appreciate it. I'll do some more research next week and start tinkering. This weekend is packed.

Usually because a cloud hosted machine is closer to the backbone and isn't hampered by the bidirectional asymmetry of a home connection so latency is low and connectivity high. Otherwise, the mining process will be slowed by the latency to a degree where it's edged out by blocks submitted by other solo/pool miners with faster connections. Ofc, if you're sufficiently well-resourced to have a fibre optic high-speed symmetrical connection at home that will improve matters. No reason you can't start with a home setup and once it's working, migrate it to a cloud-hosted server later.

Cheers

Graham

I wouldn't, necessarily.

However, for security and stability you are likely to fair much better using hosting, as most industry mining pools currently do.

Think about some DDoS protection, the responsibility of correctly distributing the mined blocks, uptime i.e. running 24/7 etc.,

I'm not saying you can't run a mining pool on a correctly port forwarded and secured 'home' LAN network, your more than welcome to, although also consider future competition and where users of a pool might choose to prefer to mine etc.,

Why would it have to be a cloud server and not a locally hosted server? Just curious...I would prefer to host locally perhaps with a cloud backup if needed...Keep in mind I know little about setting up pools so if I sound stupid...its from lack of knowledge on the subject matter.

Great initiative!

Remember that for a production pool you will need to upgrade to a future Gapcoin release, on a LTS Linux version and ideally being hosted on a reliable cloud server ...

The basic linux daemon guide can now almost be considered completely outdated: https://gapcoin.club/linux-gapcoind-setup.php

Gapcoin development and software releases may start to become quite regular from now on.

Never have any doubts to ask for help with anything in this topic.

Bit by bit, Gap by gap - together we can make good progress and the history books !

Thank you two for the input. I'll tinker around and see what I can do. I have never tried, but I'm sure I can do it - maybe with some help and a few adult beverages...I have a good ISP as far as speeds and a spare desktop, along with a passion of learning....so why not?

You could try resurrecting noncepool's old gapcoin-stratum pool, coupled with the corresponding Python implementation of gapcoin-hash.

Cheers,

Graham
 

You have a good goal by being willing to try it, multiplying the mining pool is a big support for a coin. I hope you'll find your solution, so that you can immediately do your wishes and make the older thing you have will useful again.

From the aspect of a mining pool... I could use some advice perhaps..

I'm willing to TRY to make a mining pool. I have an older desktop - an older workstation - that I originally had pfsense on but never ran it on my network here at home.

Like I said, I'm willing to try if I can dedicate that desktop for a gapcoin mining pool...

Thank you for sharing the links, gives me something to do while I work today!

Great finds indeed!
