Any plans on supporting things like the GekkoScience Compac F?

Also, is the github project (https://github.com/braiins/braiins/tree/bos-devel/open/bosminer) up to date with the latest development?, seems like it hasn't been updated for 2 years.

I just realized ztex has recently released a new board based on the Xilinx Artix 7 XC7A200T fpga, available here: https://shop.ztex.de/product_info.php?products_id=102&language=en

They come with an open source SDK: https://www.ztex.de/firmware-kit/ although that's for general use, not a ready to use miner.

I haven't seen anything in this forum about the series 2 of ztex, only the older series 1, which had an open source miner: https://bitcointalk.org/?topic=40047 but that stopped around 2013 it seems. Also it looks like bfgminer supports only series 1 of these boards.

I wonder if anyone is using these new boards, or any fpga for mining these days, maybe as a home/quiet miner for example.

Looking at this open source fpga bitcoin miner repo it looks like there hasn't been much done in about a decade: https://github.com/progranism/Open-Source-FPGA-Bitcoin-Miner

Is all the mining now done exclusively with ASICs? even the USB stick miners use an ASIC.

I wonder if there's any current FPGA device that can be used for mining today, ideally open source. Probably it won't be as efficient as the latest ASIC, but an fpga has other advantages to it, like being able to be updated over time, and use the board for other purposes as well.

You don't really need to ask that question. Just think about it.

Satoshi Nakamoto, the creator of Bitcoin, who has been gone for about a decade, is coming back to release an altcoin in 2022. And this is somehow only known in rumours, no actual proof of anything.

Does that make any sense to you?

Or would it make more sense that some random YouTuber is trying to create some hype about some altcoin so that he gets a few bucks out of the general public for free?

I think you know the answer.

Yes. Two options that come to mind below that price range:

Up to three Compac F miners from GekkoScience and a USB hub kit from BitcoinMerch:

You can run kano's cgminer (open source) with these guys:
https://github.com/kanoi/cgminer


An Apollo BTC from FutureBit

Binaries (closed source) to run the miner are available here:
https://github.com/jstefanop/Apollo-Miner-Binaries

I've seen this a few times, and I'm not sure why they would to that, since any extra information could be appended to the original post later on by editing it, which is usually what happens.

But a few threads have the second post reserved by the OP by basically posting a "reserved" below the original thread. What's the purpose of this?

Also, I thought consecutive posts were not allowed here as the mods usually deletes the second one and merges it with the first.

The original cgminer repo from ckolivas is read-only for years now: https://github.com/ckolivas/cgminer

I know that there has been some newer changes like support for the GekkoScience Compac F USB miner into cgminer, and probably others since.

Anyone knows if there's any updated repo for cgminer?

I can see that bfgminer from luke-jr is still active, but not sure if it supports the Compac F: https://github.com/luke-jr/bfgminer

Edit: I found it, from kano: https://github.com/kanoi/cgminer

Satoshi is/was a clever man.

But Bitcoin is independent of its creator.

Instead of investing time trying to find out who Satoshi is, it would be more productive to understand more about Bitcoin itself.

Nice milestone.

Companies come and go over the years.

Altcoins come and go over the years.

But Bitcoin continues to work for over 13 years with a bright future ahead.

Strange to post this in a Bitcoin forum.

With Bitcoin you're your own bank. No need for 3rd party banking services.

I kinda enjoy reading the trivia questions when posting

Fair enough, but you can get today USB4 hubs with 3A per port using USB Type-C current. You need USB-C PD for power higher than 3A.

And given that the current best USB miner works at 2A, overclocked at 3A, it seems like a logical next step to go with USB-C for the next generation, using 3A per miner.

You get to choose:


And also, looking into it, it seems that it is indeed possible to send data and PD higher than 3A at the same time, as this device states:


This seems to be in line with what the standard says:



So, at a minimum, USB4 hubs should be able to provide 3A with data per port by using USB Type-C Current, and possibly more if the device is able to do data and USB PD at the same time, as this linked device seems to be able to.

Here's more information about it: https://bitcointalk.org/index.php?topic=5392371.msg59711047#msg59711047

Fair enough, that's for the maximum power delivery of 240W.

But USB4 hubs can deliver data and power up to 3A(15W) per device.

This is from the USB Type-C® Cable and Connector Specification Release 2.1 from May 2021: [1]



And here is an actual example of this, a USB4 hub that provides 3 ports at 3A each: [2]




Given that it's getting harder to get those older USB2-3 hubs at 3A, and that they are not even standard, I think it would make sense to design the next USB miners with USB-C in mind, as the 3A per port is standard now there, and USB4 hubs are broadly available now.

Wrong name in the death certificate, signed a will leaving everything to his wife a couple of weeks before his death, wife was drinking and dancing the night of the funeral, closed casket so no one (except allegedly the wife) saw the body.

Looks extremely suspicious.

I still don't understand how they can't just follow the transactions. They said that basically people would put real assets into quadriga, and receive fake IOUs in the platform, while quadriga would widthraw the users' Bitcoin into other exchanges worldwide to sell. Well, why stop there, those other exchanges must have logs about those transactions. The documentary didn't say anything else about those.

Hallo Willi

Ich würde gerne den Buchstaben "a" nehmen, wenn er verfügbar ist, oder einen anderen, wenn er nicht verfügbar ist.

Danke für die Organisation dieser Blockpartys! 

Yes, you can just mine with any windows/linux computer using a command line application. A raspberry pi is ideal for this. You can get the binaries from here: https://github.com/jstefanop/Apollo-Miner-Binaries/releases

You can even download and setup the web UI(which uses the command line application) yourself as this part is open source (it needs a bit of tweaking to use it, but it's quite nice), and you would end up with pretty much a full system (except maybe the Bitcoin node). Here's the repo for the web UI: https://github.com/jstefanop/apolloapi/tree/production-BTC

I just realized that the latest standard, USB-C 2.1 spec, allows for up to 240W of power to be delivered in a single USB-C cable. [1]

That means that you could even power a FutureBit Apollo with it, as it comes with a 200W power supply.[2]

And USB-C hubs are now able to provide up to 60W of power per port(12A).[/s]

It would be great to see a next-gen stick miner using USB-C with up to 12A.

The GekkoScience Compac F runs at 2A with normal settings, but overclocked it requires 3A per port, which makes it difficult to find an appropriate hub for it.

In theory it should be possible to have a USB-C hub with USB-C to USB3.1 adapters on each port, allowing up to 3A to be delivered to the Compac Fs. [4]

USB4 hubs allow data and power up to 3A per port using USB Type-C current, but it might be possible that they also allow data and power up to 12A as suggested by [3]. That would be great for the next generation of USB miners.

It's very hard to find a powered USB hub that provides 3A per port because that's way above the USB3 standard, so it's non-standard by definition.

A standard USB3.0 hub has a maximum of 0.9A per port(4.5W).[1]

Hubs that support the USB Battery Charging 1.2, or BC 1.2 for short, work up to 1.5A per port(7.5W) [2]

There are non-standard/propietary ways of going beyond that. The most common value I've found is 2.4A (12W), for example that's what the 7 port hub from bitcoin merch delivers. [3]

If you need to have a hub for USB2-3 devices that deliver 3A per port you can either buy a used one (the gekkoscience one and others are all sold out AFAIK) or, if you're more adventurous, there are some people making custom developments and sharing their designs. Here's the post[4] and the actual source code for the design files of a 4-port USB2 hub with 3A delivery per port (15W) [5]. In theory you could DIY your own USB hub with 3A per port using those files if you have the skills.

Ideally the next generation of USB miners should be done with USB-C, which allows much more power in a standard way. For example, the Dell dock WD19TBS has a USB-C that provides 3A (15W). [6]

USB-C allows the creation of devices like this guy, a 4 port USB-C hub that delivers 12A per port (60W). [7]





I'm not sure if there's a way of delivering power to a USB2-3 device from a USB-C hub. But that could be worth checking.

After a quick search, it looks like it might be possible to use one of these new USB-C hubs to get 3A per port. This simple converter from USB-C to USB3.1 [8] states:
