Oh, also for learning, nightminer is excellent; https://github.com/ricmoo/nightminer

I've used cgminer a long time ago for that purpose but now I think everything has been changed. So I need a working example in order to achieve my goal.

Why not share your thoughts here what exactly do you want to achieve?
We can maybe give you some idea of what you want to achieve.

I don't know if GPU/CPU still works on mining BTC but why not buy a USB stick miner Compact F or 2pac for your project?

If you are interested check this thread below

- https://bitcointalk.org/index.php?topic=1764803.0

I like to see how connections are made to a pool and get header info in btc version 25, how merkle root replaced and calculated after 4GH nonce reached or how extranonce come to sense and also middle state involved in live action. those boards use bitmain asics and I'm not sure something like midstate could be included in asics, or a way to manipulate sha256 calculations in asics.

Re: The bitaxeUltra: Open source Bitcoin miner based on the BM1366 ASIC

- how much hashrate you've manage to get out of bm1366?

- I think you should somehow arrange your tree branch in github someway. maybe sort them by chip kind. its a bit confusing by their names IMO. hex, ultra and some number based branches...

- did you see gekko compac f? it's using much less components as far as I know, like doesn't include any microcontroller or esp for mining and solely depends on usb, right? any thought on doing something like that?

thanks again.

No.
... and you wont learn anything using it.

You're pretty much saying, I want to learn about mining for gold by picking apples at an apple orchard.

Thanks kano, you're the only remaining active developer of cgminer I assume. you did a great job.

Is there any working CPU/GPU solo mining open source software still available for learning purpose?
Preferably in C

Any help appreciated.

I wanted to let everyone know about a new revision of the bitaxe miner being developed based on the Bitmain BM1366 ASIC from the Antminer S19XP. Like the previous bitaxe based on the BM1387 (S9) and the BM1397 (S17) this is fully open source hardware and firmware.

HW development GitHub repo: https://github.com/skot/bitaxe/tree/ultra

Let's get this party started!

First, Thank you for all your efforts.

Did you find any datasheet on 1397/1398 yet?

There are innumerable ways to retrieve information about Bitcoin blocks, including previous block hash. If you're not running your own full node software, you can utilize some external blockchain explorer API to fulfill your needs. Of course, you may also need some additional software to massage the data you get from APIs because not all of them have advanced filtering to extract only the required data. For example, here is a simple script in Python for extracting block hash from specific block height:


thanks for the answer.

my question is, the nonce in header is the start nonce for mining I assume, right? where can I find exact nonce used to solve the target requirement for that block?
also when miner increment nonce, it should be placed in header and header hash recalculatet, right?

no, that should be the actual nonce... If you would re-create the header using this info and do a sha256d hash of said header, the outcome should be under the current target... Starting nonces are not included into the block header when it gets broadcasted.

but for example look at latest headers:
https://explorer.btc.com/btc/block/795162

nonce is: 0x2891b1c2 that is required just under 1TH that easily just a miner will do it under a second. Am I missing something?

Thanks guys for prompt responses.

Bitcoin mining consist of finding a nonce to add to previous block header and after 2x sha256 resulting in number lower than target.
Now my questis, where can I find previous mined block headers and solution nonce? Something that I check validity by myself.

Any plan for dual mining eth+ton?

If you are so desperate to dual mine eth + ton use lolMiner.


lolminer sucks

Which way do you prefer to transfer eth specially for small amounts?
Geth consumes lits of disk space and is hell time consuming.
MEW transfer fee is so high for small amounts

So what are other options?

25-26mhs currently.

I’m on 19mhs currently on asus p5e deluxe. A week ago it was around 24 on same machine with rx580 4gb gigabyte
Something wrong that I’m sure. But I don’t know what’s wrong.


Are you in Gen3x16?

yes its eth and it should be over 16Mh at least as epoch 404:
https://cryptomining-blog.com/12601-updated-zombie-mode-for-amd-radeon-rx-470-570-and-rx-480-580-4gb-gpus-for-ethereum-mining/



*PS: is there any compute mode in linux to be enabled trough mmpos?

Linux doesnt have compute mode and doesnt need it.  Most likely this is because of the cpu and chipset on the board.  Try swapping it. with a rig that gives full hash.  If so then its a lack of PCIe lanes as this is what slows down Zombie mode.  You need a full 16 pcie lanes to get the full speed.  So google the cpu for how many pcie lanes and then look in mobo manual and see what else uses and shares lanes.

I have a few boards that cant provide the full lanes and others that can.  Those with 16x to the slot achieve full speed the others do not.

Thanks, how much are you getting for rx580 4gb now?

If it's just the one GPU and you're using a monitor with it, that might be tying up some VRAM.
no monitor connected to system, only ssh

In any case, why make a whole new thread? Why not just ask in the lolMiner thread?

because I'm sure its not lolminer problem as I have other rigs working without any problem.
