Alternate cryptocurrencies / Mining (Altcoins) / Re: An (even more) optimized version of cpuminer (pooler's cpuminer, CPU-only)

recently I tried getting cpuminer to run on a Raspberry Pi 4 (aarch64) I'm using somewhat older codes (version 2.4) from https://github.com/pooler/cpuminerI couldn't figure out how to get it to build with the ARM assembly codes, and apparently scrypt-arm.S seemed to be written for armhf (32 bit ARM microprocessors). Hence, there could possibly with issues compiling in aarch64 (ARM 64bit instructions and OS) It's not about issues, it's just plain incompatible. Despite the name similarity, 64-bit ARM (AArch64) is an entirely different architecture than 32-bit ARM, and the hand-written assembly code in cpuminer only targets the latter. I never got around to writing optimized code for AArch64, so all you can do at the moment is compile a C-only version of the miner. |

I feel that the cpuminer is not adding fees along with block-reward. I am looking at coinbase transaction generation, code under section /* build coinbase transaction */
tmp = json_object_get( val, "coinbasevalue" );
if ( !tmp || !json_is_number( tmp ) )
{
applog( LOG_ERR, "JSON invalid coinbasevalue" );
goto out;
}
cbvalue = (int64_t) ( json_is_integer( tmp ) ? json_integer_value( tmp )
: json_number_value( tmp ) );
I feel it is missing the fees addition, below is the code I was expecting to compute and add fees. [...] The coinbasevalue field already includes all available transaction fees. |

I've been merge mining with litecoinpool for a year now and have quite a bit of data that I pull together in a Grafana dashboard. Recently, I've been trying to estimate my bottom line based on historical payouts, difficulty, market price, etc. I've been searching for the algorithm behind the litecoinpool calculator in an attempt to measure potential outputs over time. The values fluctuate fairly dramatically and thought it would be helpful for me to estimate payouts so that I can adapt to market changes. It'll help me manage the bottom line better.
My questions are:
- is that dumb (because of how drastic the values fluctuate)?
- if not, can anyone help me learn the backend math to calculate the profitability analysis?
I'd like to smooth that over time in Grafana. The API returns all the information (minus the input variables like estimated hash, power utilization, and power cost).
Any help with the algorithm?
It's pretty simple. The expected number of hashes over a period of time is average hashrate multiplied by time. You divide that by 65536 and you have the expected number of baseline shares. You then multiply by the price of a share (i.e., the PPS rate) and you get expected rewards in LTC. The formula for the PPS rate is in the FAQ on the website. As for energy costs, it's even simpler, as energy is power (in kW) multiplied by time (in hours). |

With Dogecoin being bias to PoS, is there any alternative to increase profitability, once LTC becomes a lone reward?
The pool is already merge-mining multiple chains, not just Dogecoin. The number of chains one can merge is practically unlimited, so Dogecoin dropping AuxPoW wouldn't really open up a spot for another chain. LTC+DGB for example?
That cannot be done, since neither coin supports being mined as an auxiliary chain. |

i lost my phone, who can i contact about my 2 factor authentication, cant log in without 2 factor
When you enabled 2FA, the website gave you a secret key and instructed you to write it down on paper and store it in a safe place. You can use this key to restore token generation on any device that can run Google Authenticator. You simply need to follow the same procedure to add an account to the authenticator, but instead of scanning a QR code you enter the key manually. If you need further assistance, please contact support via email (the address is at the bottom of the Help page on the website). |

What about signaling MW? I am not sure if its good for LTC. May you share your thougths about this?
Signaling indicates that the pool is technically ready for MWEB. We have applied the required software changes and performed a number of tests. I do not have a personal opinion on MW itself, but it's been in development for well over two years now, and as far as I can tell during all this time it hasn't received much opposition at all. |

it is a fact that an increase in difficulty leads to a decrease in rewards, but why did this happen?
miners are disabled in kazakhstan also miners are disabled in many large places,
what caused this increase, please tell me?
Difficulty has risen because the hashing power on the Litecoin network has increased. This means more and/or faster miners compared to a few months ago. As to how exactly this happened, we have no way of knowing for sure. We just know that the mining network as a whole is faster because it can now solve a block that is twice as difficult as the blocks we had last July in the same amount of time. |

Past 24 hours Rewards was 0.15-0.18 LTC , ( Antminer L3+ Workers 4 , average Speed 2,500 MH/s ) But final several month it going down to 0.10 - 0.11 LTC - 24 Hours what is the reason? As I know In Kazakhstan miners turned off also many big countries restricted mining and I should make miners earn more ?!
Difficulty has about doubled since last July, going from 7M to 15M, so the hash power on the network has definitely increased. And miners' rewards are inversely proportional to the network's difficulty. |

hi! please add a value in BTC and USD next to the "Past 24 hours Rewards" field, you already have all the courses, I think it will be easy to do.
We will consider it, but personally I'm not a fan of this idea. I think the Rewards section should contain exact figures only. The pool deals in LTC exclusively, and adding any estimates that depend on (potentially highly volatile) exchange rates may be seen as misleading by some users. |

Is there a way to download the User Hash Rate data that's used to generate the Charts?
Currently, no, but if you only need daily data points you can download the CSV from your Rewards page. I'm seeing about 1.7% stale shares with Antminer L3+. Ping time to us, us2, and generic addresses are around 28 ms, 66 ms, and 98 ms, respectively: [...]
I recently upgraded my cable modem and upgraded from CAT 5/6 to CAT 8 cabling and reduced the number of internal switches in the path from the miners to the modem. So now I'm at a loss as to how to further reduce the stale shares. Any suggestions?
I would guess that the two most likely possibilities are that the bulk of the latency arises either at the miner's level, before shares are actually sent over the network (which could happen because of a hardware or firmware issue or quirk), or at some point along the network path (e.g. by a firewall examining TCP traffic, which wouldn't affect ping times). |

Hello I am rather new to the mining scene and this is my first post I hope I’m addressing to the right person lol.
I’m just wondering why the coin price has gone up but I am making less profit? I understand about the difficulty but comparing to similar difficulty levels in the past I’m still making less than I was before
I was hoping someone could help me with this?
Essentially, the network difficulty has been going up and the relative profitability of merged mining has been going down. On the positive side, the price of Litecoin against fiat currencies has gone up. |
