Without pricing listed I assume the early adopter is in for a lashing....

Those are NOT by any stretch of the imagination "GPU's". They are ASIC-based miners in cases that for whatever reason use a GPU-style of footprint. Stupidest idea ever....

I dunno from my perspective if they could leverage all 75W of the PCI-e port and deliver a ton more hashrate to match the bitaxe and other asics these could be a brilliant idea.

All is fair in love and crypto mining.

Early Jan 2025 the 20 min reset should be removed and Testnet won't have this issue any further.  Full POW is clearly the way, Testnet has pool activity now too, which is far different than back in the day.  

I'll definitely mine with y'all if it is ever open to the public or if you need a tester for some blocks.

Right now, I'm on BTClab.dev, paying a 10% fee.

My blocks include transactions as well:  https://mempool.space/testnet4/block/0000000000000002cedaf2784715288a9b3765e71d2c6c6c4b9c040b092a1e5d


Soon. We are testing all aspects of block creation with the most recent version of core on testnets 3 and 4 and regnet.

When we launch (not too far away in public testing) we will have a fully unique coded Mainnet, Testnet 3 and Testnet 4 pool.

Submitting blocks with 0 data / or only 1 transaction maybe faster.....

But ends up being essentially useless for real dev imho....

Here's doing it right...

My Apollo II Full Node has a static IP. How can I direct external miners to connect to my node and mine?

You need a static public IP to be clear or you need to setup DDNS.

If you have a static public IP then simply add the following to your external miner pool config:

stratum+tcp://YOURSTATICPUBLICIPADDRESS:3333

Have them set their user/workernames up as BTCADDRESS.WORKERNAME with a password of x.

And assuming you've got your network / firewall settings correct you should be in business.

Seems like the latest firmware doesn't play well with backup pools.

Tested on 2 separate pools and the same result the unit hangs on pool 1 even after 10 minutes of pool 1 being offline.

Oddly enough this does not happen on the mini.
7  Bitcoin / Hardware / Re: Avalon Q on: May 17, 2025, 05:58:36 PM
I've been away from the scene for a while although still check in on the forum occasionally. Can someone tell me why home miners like this require you to only use a specified pool? Can you not point it to any pool you choose??

I have the Nano 3 and the Mini 3 you can configure any pool you like on those. On those 2 units you have the ability to configure 1 primary pool and 2 failover pools of your choosing.

One would assume that the Q is no different.
8  Bitcoin / Hardware / Re: Official FutureBit Apollo II/BTC Software/Image and Support thread on: April 29, 2025, 12:27:30 AM
If a miner connected to the Apollo II node hits a block, does the blockchain automatically send the coins to the wallet address in the worker name? Or are there steps that we'd need to take to receive the BTC in our wallet?

If you are using the built in solo mining option (which uses built in ckpool) on an Apollo Full Node and happen to find a block then the BTC address of the miner that found the block will directly receive the rewards assuming it is a valid block.
9  Bitcoin / Mining / Re: Has anyone here actually found a block while solomining on: April 21, 2025, 04:53:31 PM
I did hit a block on CK's pool with a GekkoScience Compac F USB miner back in 2022!

Back when the network difficulty was 26.6T

It only takes a single chip and a ton of luck...

Glad that worked out for you.
11  Bitcoin / Hardware / Re: Canaan Avalon Nano 3S - No connection to any mining pool on: April 06, 2025, 01:03:20 AM
Sounds like a security setting is enabled on your router which is blocking your miner.

See my comments on this thread they still are valid today.

A BitAxe Ultra at only ~ 500GHs just hit a block!!

https://x.com/Crypto_Mags/status/1899238110208393640

Edit: looks like it had a little help, but not a whole lot.

And best share/difficulty it hit was 700T, holy cow!!

Keep things on topic....

Uh, solo mining is off topic?  I thought that was what the Apollo II was all about?  And if 500GHs can hit a solo block, then it's possible for 9THs to hit a solo block.  Now do you understand?

Um.....

Your post had nothing to do with the Futurebit Apollo II BTC or support of it which is what this entire thread is about.

Now after my clarification maybe you'll understand why its OFF TOPIC  Roll Eyes .

Anyone want to share their experience with the Mini 3 and Nano 3S?

I'm considering buying a few of these to replace heaters in rental houses, but I'm a bit concerned about stability.
I've seen several people posting about different issues, but I'm not sure if those are serious issues or not.

The houses in which they will be placed is far away from where I live (7 hour drive), so I can't be driving back and forth to fix minor issues, they need to be stable.
I saw that the app only works if you are on the local wifi (which is a shame and missed opportunity for customers like me), but I guess I can manage them through a VPN.
I assume they can be managed through browser on IP, in addition to through the app?

Any feedback is welcome, thanks!

PS: I've been locked out of my Bitcointalk account for years, finally got it back today!  Cool

Have the Mini 3 and it's an absolute tank size wise.

On Eco mode it produces a good amount of heat with just under 30TH to the pool.

In less than 2 weeks of running it the filter is already at 11% so keep that in mind since you'll have a distance to travel.

App and web browser are required to access the gui but you can only change the settings through the app so you will need to be on the local network and sounds like you'll need your VPN.

Most of the time with the Nano's when they act up a simple powering down and back up fixes the issue but haven't had that issue yet with the Mini 3.

Welcome back.

I just pushed my headless Apollo II over 2 PH/s with a few remote rentals along with my local miners while solo mining. All of these are low and medium difficulty miners. Has anyone tried using high-difficulty miners on their headless rig? And if so, please relate your experience in doing so. Thanks.

Cheers!

Can anybody answer this question? Thanks.

Cheers!

If you are referring to "pro level" miners like M50's, M60's, S19's & S21's as being "high-difficulty" then yes. The built in pool running CK's pool handles the connection from those miners quite well and will adjust their difficulty based on their hashrate.

Now if you are going to try to rent a chunk of hashrate from a place like Nicehash then no as the default pool difficulty is set too low by default to be compatible with their service. You would need to adjust the CK pool code to have a higher starting difficulty in this case.




...

Other questions:
- For the (very unproble case) that my Apollo Solo Miner will maybe find a block (lottery) in the future somewhen, where would this be shown in the Apollo 2.0.6 Web-IF?
- Anyone knows why Apollo miners use private MAC addresses?

Anyone able to answer these 2 questions? :-)

I can answer the block question.
You will see the highest share listed clearly (which will need to be over network difficulty) on the solo mining page.

Now the other question....
Mac addresses are hard encoded into every network card so not sure what you are referring to here.

Has no one bought it yet ?

I bought via Indiegogo and they've said they'll be shipping late February. That said not sure if it'll show based on the CBP news...

In the same boat waiting for Feb delivery.

I can confirm that the SAMSUNG 990 PRO w/ Heatsink SSD 2TB, PCIe Gen4 M.2 2280 Internal Solid State Hard Drive DOES NOT WORK with the Apollo II.

The drive with heatsink is too large first off and secondly the drive will crash at some point. They work initially but then crash out causing the node to fail.

I experienced this with 2 of them so I would steer clear of them at all costs for this application.  Grin
20  Bitcoin / Hardware / Re: Bitmain S19K PRO failure rate on: February 07, 2025, 07:26:31 PM
Too bad there are still no good (or any) alternatives. So we keep giving bitmain a fortune for questionable service + product.
I don't have high hopes that it will change soon...
There are at least 2 other alternatives: Canaan and Whatsminers. While both are slightly less efficient, both are far more reliable.

My experience with Whatsminers (M50 line) is that they just don't recover from curtailment in a timely manner.

As a result I have stayed away since discovering this the hard way. And yes I have tried fast boot etc in their firmware.

Can't comment on the "Pro" side of Canaan miners.



The S19K's flaw seems to pertain to expansion and contraction of the soldering between the chips when there are extreme temp changes.

Additionally the S17 heatsink design flaw fiasco was carried over to many of the S19K models which is utter crap.
