The newest member of the
#bitaxe
lineup, the bitaxeSupra is working! Single BM1368 ASIC (from the Antminer S21) running around 620 GH/s. Open source everything.
Another huge effort from the Open Source Miners United crew on figuring this one out!
It's safe to say the bitaxeUltra is working! Single BM1366 ASIC (from the S19XP) running at 527 GH/s and 20 J/TH. Open source everything.
Massive props to the Open Source Miners United crew for figuring this one out!
Putting the final touches on the bitaxeUltra so we can finally release it!
This fully open source
#bitcoin
miner has a single BM1366 ASIC (from the S19XP). It runs quiet and cool at just about 500 GH/s
The bitaxeUltra is an open source
#Bitcoin
ASIC miner project based on the BM1366 ASIC used in the Antminer S19XP.
This is the first prototype, and I'm very excited that it's kinda-sorta working!
I am honored and excited to receive an
@OpenSats
grant to further
#bitaxe
development! Together with the OSMU legion we're bringing open source
#bitcoin
mining to everyone.
Huge thanks to everyone at OpenSats and the donors that support. Y'ALL ARE HOW WE WIN.
OUR FOURTH WAVE OF NO STRINGS ATTACHED OPEN SOURCE BITCOIN GRANTS:

The latest version of the BitaxeUltra, version 204 has been released!
This version includes all the bugfixes and DFM improvements learned while getting over a thousand

Huge thanks to

I have been head down lately on day job work, but this

Right around 500 billion hashes a second, every second of every day.
OSMU member pmaxuw has been making incredible progress on a QUAD BM1366-based open source miner. This thing is seriously rad.

This is how Bitcoin was designed to work.

It's true; anyone can build and sell

modules working (at least they were before cleaning 😅). A carrier board, named Flex4Axe, using all 4 modules for mining is coming soon. Hope it works 🤞
Cancelling Phoenix Wallet in the US sucks. The fact that this can even happen is a symptom of centralization. I think Bitcoin’s biggest risk is this same thing, via centralized miners and pools.
Open source fixes this.
The aditBoard is a USB adapter for Antminer hashboards. It can be used with the upcoming Bitcart controlboard, or standalone with a PC. Open source hardware, and eventually firmware!

This is huge, thank you for the encouragement

I’m a big fan of your work! I’d be happy to give you a bitaxe.
Let’s keep Bitcoin open source!
Solid take. Ignore naysayers and profit-motivated critics. Just keep building what you love

It was raining pretty hard here the other day, but I got lucky: according to ordinal theory I got one of the first ever drops of water from the Atlantic Ocean. I’m willing to sell — serious offers only.
Bitcoin mining centralization is a direct result of it becoming an investment. Fiat investors need low variance returns, and that's only something the largest pools can provide.
That's not ever going away, but we can counterbalance it through a healthy ecosystem of home mining
Bitcrane v2, the USB Antminer controlboard is alive! This revision fixes a few bugs in v1 and adds support for 3 hashboards.
Run your miner firmware from the comfort of a PC 😎
If we got 1 million bitaxe out there (tough, but not impossible) that would be around 0.6 EH/s. One

Today was a historic moment in our journey towards hyperbitcoinization. The former and next President of the United States gathered America’s hashrate and committed to championing our cause in DC and on the global stage. Bitcoin will THRIVE in 🇺🇸
Orange Man+Orange Coin= Good
The good news is that this is an open source design. So if the bitaxe economics don't work out for you in your specific situation, now you have the starting point to make a machine that does.
If you intend to buy a bunch of miners and set them up in a big 24/7 grid-connected
Bitaxe board 95$
They say the chip is 15$
So thats 110$ + shipping
$208.72+shipping per TH and you will make less than 3 cents a day revenue.
Fun if you want to tinker but don’t pretend like this is a game changer or an investment. It is a hobby toy.
November 1910 the Jekyll Island Club in Georgia was the site of a secret meeting formulating the Federal Reserve as America’s next Central Bank. Today it’s a Bitcoin mine.

Unfortunately one Antminer S21 200TH/s does nothing to decentralize the network. At US national average electricity rate of $0.1668/kWh it is not profitable and it’s unclear if it could ever ROI
Should Bitmain stop marketing this toy?
Here we go; the S21 features the BM1368PB!!

The only problem now is too many good ideas have come back and not enough time!

& dropped it completely for free
then open sourced it
& none of the big accounts are talking about it
This was a grim prospect just a few months ago. Mining commentators repeated “won’t work” ad nauseam online. Any curiosity was shut down as “don’t try, not profitable”.

A single custodian now controls the coinbase addresses of at least 9 pools, representing 47% of total hashrate.

This is really wild; two Nano3 users have discovered their stratum details were changed without them doing so..
Do you have a Nano3 you’ve been running for a while? Login to the dashboard and see if your stratum settings are still what you originally set..

We are selling for $40. But this is FOSS. You can make your own too. We can also just sell the components that we purchased at volume discounts.
This is why we need to decentralize away from the mega pools/miners. No one entity should have enough network hash rate to reliably offer this service.
