Specifications:

PoW: custom, prime gapsBlock target time 2.5 minutesBlock reward proportional to the current difficultyBlock reward halving every 420000 (about 2 years)Cap: about 10 - 30 million GAPDifficulty 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

Gapcoin should automatically connect to the network,
but if you get problems, you can add these nodes to your gapcoin.conf file:

Code:

addnode=212.227.143.155
addnode=104.131.69.82
addnode=95.215.44.9
addnode=155.254.36.179

New RPC calls:

Code:

listbestprimes amount (min merit)

Returns a sorted list of the best prime gap merits.

Arguments:
1. amount        (numeric). number of prime gaps to display
2. merit         (numeric, default = 16). minimum merit to display


Code:

listprimerecords merit

Returns a list of all prime gaps with the given integer merit.

Arguments:
1. merit        (numeric 1,2,3..) the prime gap merit.


Note: The above rpc-calls can take a long time to respond.

The formula π(x) is known as the prime-counting function, which graph shows the prime gap distribution as well.

algo?


searching for large prime gaps

a novel one, apparently. You can't use any existing miners.
