Website: gapcoin.org (http://gapcoin.org)
Twitter: Gapcoin (https://twitter.com/Gapcoin)

Specifications:

• PoW: custom, prime gaps
• Block target time 2.5 minutes
• Block reward proportional to the current difficulty
• Block reward halving every 420000 (about 2 years)
• Cap: about 10 - 30 million GAP
• Difficulty adjusts every block and increases logarithmic (it will probably take years to get to 50)

Fair launch:

• Gapcoin was not designed to enrich the early adopters or the coin creators! The more people mine Gapcoin, the more coins per block will be produced. (Coin supply will increase logarithmic with the difficulty, this means it will grow in the beginning, but later, it won't change much.)
• There won't be any premine!
• To avoid instamine, the reward of the first 1152 blocks (about 48 hours) will increase quadratically to its absolute value: the current difficulty. Block reward will be 1/1152^2 * blockheight^2 * difficulty for the first 1152 blocks. This should guarantee that the difficulty is stable until the blocks yield a worthwhile amount of coins.
• Source code will be available before launch (excluding the PoW function), so everyone can setup their own environment, compile the software, and check if everything works.
• Windows and Linux binaries will be distributed in an encrypted container before launch, the password will be revealed at launch.

Launch date: Tue Oct 21 2014 - 18:00 UTC

Edit: Website now contains a mailing list.
Edit: Reward scheme changed: Block reward halving every 420000 (about 2 years) with about 10 - 30 million GAP.
Edit: We have an new and unique logo.

Launch thread: https://bitcointalk.org/index.php?topic=822498

CPU only, right?
Such block reward scheme will probably lead to dumping I'm afraid :/

Any estimation for release?

Seems interesting.

Yes


In the beginning maybe, but once the difficulty has stabilized, the block reward won't change much.
Due to the logarithmic difficulty increase, the block reward will only have significant increase at the start.
This will effectively avoid instamine!

Ok this will be my first coin ever to mine right as it lunches! I can't wait!

Interesting idea.  Will you be releasing a whitepaper?

Maybe, but the website (http://gapcoin.org) covers already the most parts.

Interesting  :) Keeping an eye on it.

I wouldn't pass the source code to anyone before start. You should know why.

From the website:


Anonymously, or "anonymously"?  :)

Thanks, Nice read.  You guys have done your homework.  :)

So does this mean the primecoin gpu miner could be ported to this coin. If I understand correctly, you need to find prime numbers to work out prime gaps?

Source code will be available before launch (excluding the PoW function).
The hashing part will only contain prototype functions.
You won't be able to do anything with it, except checking if you setup your compile environment correctly.


Anonymously as in Bitcoin "anonymously"  ;)



Theoretically yes, but it will be much harder than just copy paste.


Yes

Seems interesting, will keep a watch.

Suggest you update logo

I know its just a template, but there could be a logo contest.

You could use this prime-sieve program as a logo:

That would be pretty cool if it were fancied up a touch.

i will watch this coin  ;D
CPU? is this CryptoN?

Will you be releasing a python PoW too? for P2P Pool... and Javascript would be cool too, so NOMP can include it ;)

NOMP seems to be pretty cool, but first of all the coin must be created ;)

Yeah... i know, but one of the first things that must be handled for these new cpu algos is the pools, because there are some guys with serious cpu mining power (*cough* *cough* botnets *cough*) that rapemine these coins like no-one's business.

Just saying, this algo seems pretty spiffy, being a math geek myself, i'm liking all these prime PoWs.

Anything new to report about this coin? I can't wait to see it lunch!

Iam going to follow this, looks interesting!

Just for references, what was the previous reward scheme? I don't remember. Watching this thread for a while now :)

A hard cap without reward halving every 420000 blocks.

Was a great fantasy while smoking opium





?

Update:

• PoW code rewritten form simple proof of concept C to object oriented readable C++.
• Code integration started with bitcoin v0.9.2rc2, looks good so far.

The motive of the circle is inspired by the prime number distribution.
Starting with digit "3" at the top, it proportionally shows the size of the gap (black) between two consecutive prime numbers.

 :)

explain how i can start to mining im begginer with this give me the script

It shows gaps 2,2,4,2,4,2,4,6,2,6,4,2,4,6,6,2,6,4,2,2.
That last gap ending back at the top is wrong. It should be a 6-gap (from 73 to 79), not a 2-gap.
In fact it's obvious that you can only get consecutive 2-gaps at the start.
You can argue that it was a 6-gap that got truncated by reaching the top, but that would be rather obscure and misleading. It would be better to remove it to indicate the discontinuity.
Or you can argue that it was wrong on purpose just to make it look symmetric at the top. Which is not how we do mathematics.

So the 'old' Gapcoin logo presents said graphical anomaly as per the above ...

- https://en.wikipedia.org/wiki/Prime_gap

"The first 60 prime gaps are:

    1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2, 4, 6, 6, 2, 6, 4, 2, 6, 4, 6, 8, 4, 2, 4, 2, 4, 14, 4, 6, 2, 10, 2, 6, 6, 4, 6, 6, 2, 10, 2, 4, 2, 12, 12, 4, 2, 4, 6, 2, 10, 6, 6, 6, 2, 6, 4, 2, ... (sequence A001223 in the OEIS)."

Can you refute Gapcoin's on-chain Prime Gap records ?

Interesting! Why is your website not secure?

- https://gapcoin.club is secure / secured.

We do not (currently) have any control over the original gapcoin.org website.
