17 years after Bitcoin's creation:

• still 10 minutes per block
• still capped at 21 million
• still adjusts difficulty every 2016 blocks
• still decentralized
• still open source
• still SHA-256
• still 99.99% uptime
• still never hacked
• still immutable
• still growing

Yet most people still think it's going to zero.

[Braiins Forge @Braiinsforge]

There is a version of this business where we treat every other home-mining project as a threat.

We want no part in that.

The plebs soldering their own boards, the Bitaxe builders, the 256 Foundation, the people forking open pools and writing firmware in their spare time.

They are not competition to us. They are the reason home mining is alive at all.

When the big money drifted toward warehouses, that crowd kept the idea going that a regular person with a small machine still belongs on this network.

So our plan is simple. Support their devices inside our ecosystem instead of locking ours away from them.

Build a software stack that plays nicely with the gear you already own, whoever made it and grow the tent rather than guard a corner of it.

We believe a bigger, more open home-mining community is good for Bitcoin and good for us.

The healthier that whole world gets, the more reasons anyone has to run a machine at home (ours or otherwise).

We would rather earn your trust by being useful than trap you by being the only option.

None of this is charity. It is just the version of the future we actually want to live in, where mining stays spread across thousands of desks instead of a handful of buildings.

If you are out there hashing on something you built yourself, you are one of us already.

Keep tinkering and keep sharing.

We are pulling in the same direction 💪🏻

Genuinely, socialism is the best sounding system.

It makes perfect sense for a society to work together to elevate the living standards of everyone together.

It makes sense that if someone builds something of enormous value, we accept that it was inevitable that it would have been created at some point and that it was society as a whole that went into the discovery.

It seems fair that we would all accept that people have vastly different abilities that yield very different commercial value. How unfair that the person who is naturally good at negotiating a roll-up acquisition strategy is wildly more rewarded than the nurse who returns someone to health or who allows someone to die with dignity.

Honestly, I see it. I understand it.

The issue is that we are primates running on ancient software. We don’t do stuff for the collective good, we do stuff for our kids.

The person who strives for an A on the exam doesn’t study if the grades are equalised. The entrepreneur doesn’t start the company when half the rewards are redistributed to those who didn’t - even though they couldn’t.

We’re happy sharing to an extent but we’re not content to put it all in the pot. We’re happy to help those who clearly cannot survive on their own but we’re not happy supporting those who don’t want to work or who struggle to get motivated or focused.

Socialism is the smartest system but it doesn’t actually work and has never worked. Really smart people like socialism because they can see how much better society could be … if only it worked.

Even John Lennon kept the royalties to Imagine. His heirs will never need to work again from that one song alone. If he truly believed what he was saying, he would declare that it belongs to “all the people living for today”.

Capitalists accept human nature. We know there is a better way but we know it’s out of reach. We understand that if you can harness self interest in a pro-social way you will lift living standards enormously. The restaurant owner will feed the village not because it’s good for society but because it’s good for his kids… either way the village is fed. John Lennon will write uplifting songs … but only if he owns the rights.

The most important part about capitalism isn’t that it’s better - it’s not. It’s that it actually works in the real world.

The new Forge miners are coming.

But good things take time, so we're giving away free hashrate to fill the wait.

Post your best Bitcoin or mining meme in the replies.

We'll pick our favorite and hand the winner a $100 hashrate boost.

Closes in three days.

Show us what you've got 👀

Edward Snowden said it the best:

"When you say 'I don't care about the right to privacy because I have nothing to hide,' that's no different than saying 'I don't care about freedom of speech because I have nothing to say.'"

"Simply because you are following the law, doesn't mean that you'll be exempt from governmental interference in your private life."

@steidacz LFG těším se na finální verzi, bude k tomu rovnou i minihra? :)
To by mohlo mit dobrý potenciál 'viralnosti' podobne jak se 'hrala' D21 volba prezidenta.

Call me crazy, but I think parents should determine what their teenagers do online rather than the government.

And that governments shouldn't use system-level ID checks to identify and monitor everything.

[Braiins Forge @Braiinsforge]

Your BMM 101 takes 144 swings a day at a solo block.

We are building the new Forge miners to make every one of your swings bigger.

Here's what they look like:

[Eli Nagar @EliNagar]

We've spent the last months building for the community.

Now it's almost time to show what we've been working on.

If you're at BTC Prague, come see it in person. If not, follow us.

We've got a lot coming.

The AI hype feels a bit like the 3D printing hype about a decade ago. Back then, the enthusiasts foresaw a 3D printer in every home, revolutionizing product manufacturing, part replacement processes, construction... Some of those came true, but for most ordinary people, it was a solution without a problem.

Arguably, the AI models have a broader utility than 3D printers, but most people will have no problem for this solution, and it will find a use case with industry specialists, just like 3D printers.

[Alex @alexpilar]

The most important things are never forged in the mainstream.
They emerge from garages, cypherpunk mailing lists, obscure forums, and 3 a.m. chats between those who refuse to accept the world as it is.
It’s hard. The odds are not good.

But the future has always belonged to the few willing to look unreasonable long enough to prove everyone else wrong.
See you in Prague next week.

@0xSero Whta risers for GPUs do you use?

[VLAD HOSTS THE BEST PODCAST IN BITCOIN @Vladcostea]

You know, I really respect bcashers for being true remnants

9 years later, even after they had 2 major community splits (BSV and XEC)

even after the lead developer left

even after market has clearly favored small block BTC

while the hashrate is ~1% of Bitcoin’s

they keep going

lots of high profile big blockers dropped their support around 2020 to embrace Ethereum

but there are still devs shipping new features and OP codes that put Bitcoin Core to shame

in spite of having fewer resources.

Never had inflation bugs, the lesser degree of conservativeness didn’t make the dev team sloppy

They even reported the 2018 inflation bug in Bitcoin, didn’t try to exploit it in a time when they could easily become destructive.

Wasabi 2.0 was inspired by Cash Fusion, many of the covenant proposals are iterations of the already available OP_CheckDataSig and the reactivation of OP_CAT.

The big blockers actually did a great job scaling Bitcoin, settling for dynamic 32 MB blocks that can be bigger only if the user pays for it, and ironically setting up much stronger foundations for trust minimized L2s. They can even run a better version of Lightning, with fewer hiccups.

Without any grants from HRF, Jack Dorsey’s companies, MIT, or mainstream financial institutions – which is probably why they were able to ship code instead of trying to find the meaning of the word “consensus”.

Bitcoin Cash did a great job scaling and making Satoshi’s codebase more useful. I wish Core would learn and try to compete instead of “bikeshedding”.

I also wish it wasn’t taboo to look at competing codebases and take the best parts. You know, like actual cypherpunks who don’t need to signal loyalty to a church in order to be taken seriously.

@bradmillscan I run it on self-hosted models nad did not have any of such headaches (so far), i run it for 2 weeksonly though, so issues might appear :)

[Alex Veremeyenko @alex_verem]

Let me trace the timeline here because nobody's connecting it.

Step 1: Scrape the entire internet. Every book, every article, every conversation, every piece of art, every forum post. Do it without asking. Do it without paying.

Step 2: Train a model on all of it. Call it "artificial intelligence."

Step 3: Go to BlackRock's Infrastructure Summit and announce: "We see a future where intelligence is a utility, like electricity or water, and people buy it from us on a meter."

Step 3 is where you sell people's own knowledge back to them. On a meter.

They took the collective output of human thought, compressed it into a model, and now they want to charge you by the token to access a version of what you and everyone you know already created.

One Reddit user put it perfectly: "They stole all this data from us, the people, our life's work, creativity, art, by devouring the internet and blowing through all copyright laws. Now they want to sell it back to us in the form of a utility."

Imagine if someone photocopied every book in the public library, burned the library down, and then opened a subscription service for the copies.

That's the metered intelligence business model.

And they're pitching it to infrastructure investors as though they invented water.

@jun_song The ux of sending crypto is terrible due to way how it fragmented to verious chains and 100s of L2s. Also no crypto can really sclae to sth like 'pay per api call', tte only viable tech is Cashu/ecash on Bitcoin of course.
Literally sending money 'as a string'

Farmer: "Gentlemen. I'd like to present the ultimate plant-based protein technology."

Investor 1: "We're listening."

Farmer: "It converts inedible plant matter into complete protein. Grass, cornstalks, brewery waste, vegetable peelings. Anything cellulose-rich that humans can't digest."

Investor 2: "Energy requirements."

Farmer: "Sunlight."

Investor 2: "For the plant matter, you mean."

Farmer: "And for the conversion. Same sunlight. Reused."

Investor 3: "Heating costs for the bioreactor."

Farmer: "None. The unit holds 38.5 degrees year-round on its own."

Investor 1: "Failure rate."

Farmer: "Self-repairing. The unit also replicates once a year at no additional cost."

Investor 3: "Replicates."

Farmer: "Produces a smaller version of itself. Which becomes a full unit."

Investor 2: "Net carbon."

Farmer: "Neutral. The carbon in goes back to the air the grass pulled it from. Round and round, same atoms, no new ones added."

Investor 1: "And the waste output."

Farmer: "Twenty tonnes of soil enrichment per unit per year. The waste is also a product."

Investor 2: "This would obliterate Beyond Meat."

Farmer: "It already has. They just don't know yet."

Investor 1: "Where can we see one."

Farmer: "There are about 1.5 billion currently deployed. Have been for ten thousand years."

[silence]

Investor 3: "It's a cow, isn't it."

Farmer: "It's a cow."

Investor 2: "We were promised plant-based."

Farmer: "The plant goes in one end. I don't know what else you wanted."
