Hey,

Current supply on coingecko (17,634,537) and CMP (14,369,569) was not updated for a some time, because well, no any working blockchain explorer.
So I calculated it for the block 2120000 (we at ~2129300 now) and added this info to my table.
about 17 874 521 GAP at the block 2120000.

Yes, the last explorer is now gone since months as the subscription wasn't renew in time...
The last one online was @ https://chainz.cryptoid.info/gap/

It seems sometimes we have 3 nodes on satoshi9.2 connected.
I can connect to them from Windows machine but not from Linux machine.
But they all disappeared today from my nodes even from Windows machine.
Maybe it has something to do with me adding port=8334 to gapcoin.conf, but maybe not and it's just a coincidence.
Because I could not connect to them from Linux machine at all, I forwarded a port and connected my linux desktop node to my windows node.
I guess now anybody can try to connect to it too (not sure if it will work):
178.141.100.234:31398
EDIT: I removed this node from my linux machine, because with it mining continues even if there is no connections from outer nodes. I do not want forks.
Main alive node de-facto is still:
88.66.203.169

82.66.203.169 is mine, yep it's more or less the main one at this point. I got the network unstuck in August with this one.
I did open the port 31469 for this machine.
With this port (TCP/UDP) open, you should reach ~12 nodes.

About Nvidia miner: it actually works fine, I just forgot to add -a nvidia to .sh
It seems I can launch multiple instances and they do different work, but I'm not sure about that.
If it's indeed so, then from rtx 3060 with decent multi-core CPU we can get at least 8M primes per second, probably even 10-12M and more.
But it seems it's not possible to mine any shift but 32 on GPU miner. -f parameter is ignored. If anybody know how to change prime shift in
GPU miner, please share this knowledge in this thread. Even only working 16 or 64 shift will make mining much more fun.
On 32 shift we have the world record aka the biggest merit in the blockchain, no hope to overdid that.

Good.
Indeed, the gpu miner is hardcoded on shift 32. I don't remember, but i wasn't able to edit this and compile at the time.
The Gapminers are very CPU intensive yes. Parts of the calculations are still running on the CPU and couldn't be moved to the GPU, as i know.
8MPPS is a very nice value for a 3060 tho. I think i got only 3, can't test rn.
Or you're running multiple instances of the miner on the same card ?! This may indeed increase the total as well, if the CPU allows it.

FYI: The GPU miner is basically the CPU miner, doing the same job but faster.
The CRT miner is using the Chinese Remainder Theorem.
This way, the miner can mine higher shift. At first, the limit was 256, then 512, then 1024. To go higher would imply some security issue regarding the PoW.
All this to say : The limit where the CPU miner or the CRT miner is better is around shift 128.
You will prefer to use the CRT miner above 128, and the CPU miner below.
There is also a big drop in performance between shift 64 and shift 65.

You can find some stuff here.
It's quite a mess ahah, and would need some explanation ofc. But you can find some additional informations about the Gapcoin and some of my tests.

I tried to build miner from source, CPU version no problem, it's compiled fine and works fine afterwards, but no luck with GPU version, probably because I tried to build CPU branch with GPU settings instead of GPU branch
(I've built some binary file for GPU eventually, but it's not working properly and file is different from released miner). Maybe I will try my luck with GPU branch later.

All the binaries will be harder to compile over time, unfortunately..

I think the only way for mining to survive is to somehow get some support from hobbyists, who will mine mostly just for sake of it. Even at 10 sat per GAP,
current daily profit from all mined coins is about $2 (0.6GAP*24b/hx24hx10sat). I can buy some from time to time, but it's basically a donation, I have no intention to sell them and I have no much hope that it will be ever possible to sell them later for profit (or even buy some goods, lol, it's a cryptocurrency after all).

Huh, it would be very cool in another context. But honestly, don't waste any money on the markets without a more global plan.
I injected something between 0.25 and 0.5 btc since 2018, it's probably why it's still not at 1 sat.
You'll just feed some greedy people without any interest in the Maths.

Another thing is halvings. They are happen very fast. Honestly I have no idea how even Bitcoin itself will survive them. I prefer the Monero way with constant tail emission. Of course we have no coordination (and probably no skill to build a new wallet) to hard fork GAP for a constant 0.6 (current) or at least at 0.3 (next halving) per block. Primecoin way to go regarding block rewards is also much better in my opinion.

Not much to say about this..
Nota Bene: The reward is also indexed on the difficulty (logarithmic).

About "death of the coin". Question is: do we want such project to exist - not in a sense of cryptocurrency, but as a math distributed computing project? I think the answer is yes, so why to launch GAP-2 when we already have it? As long as somebody mine it, as long as coin is more or less alive, we have the blockchain with all results and also a chance to improve them. If anything, we need somebody from Primecoin or Riecoin team to be interested to support the project. Maybe some old whale can send somebody who can have some interest in GAP some tens/hundreds of thousands of GAP, so such hypothetical dev will have some incentive for price to rise.

Huh. The last OG interested in the project was BitcoinFX. This guy literally responded to the welcome message of Satoshi on this forum.
The last Dev was M. Higgins.
And i was the last lambda guy interested as you seems to be in this project.
None succeed in this task to get the Gapcoin project attractive again...

Here is my gapcoin.conf main lines (windows) :

Code:

listen=1
server=1
daemon=1
port=31469
rpcport=31397
rpcallowip=127.0.0.1
rpcuser=rpcuser
rpcpassword=rpcpassword
maxconnections=24

Check out the About section of the QT, M. Higgins added a really cool story (;

Cheers ! 🥂
