two main reasons:

1. its a replacement controlboard for when you need a way to interact the miner with additional sensors or actors, like a temperature sensor, or controlling an additional fan, pump etc. In the past the real only way to do this was to have a RaspiPi that is connected to the sensors and actors and then talk to the miner via the API. this is unreliable though
2. You want to run on your miner more than just the firmware, libreboard will allow you to run homeassistant, a full bitcoin node or anything else right on the miner.

there are some, yes:

• https://ambrook.com/offrange/crops/bit-coin-waste-heat-greenhouses
• Abundant Mines, an Oregon-based miner created a greenhouse that grew crops.
• https://upstreamdata.com/resources/media/harnessing-bitcoin-mining-heat-a-greenhouse-revolution

I think Antpool would be extremely interesting to hear their position on the pool situation, like why they are hiding that they actually have more hashrate than they claim.

Or Foundry, to see their point of view, but also to ask how hard it is to create a mining pool in the US with all the regulation and compliance. As I think we need multiple "regulated" mining pools, but nobody really wants to do it.

similar to this: #1530845

Basically the mega miners will slowly fade away and bitcoin mining will be more and more embedded where the heat (and cold) produced can be reused for a secondary purpose.
I believe in 20 years every house/building will have a bitcoin miner in it to generate heat.

sorry, this should have said "criminals" not illegals

I guess it depends on taste, there are some ideas to make them prettier: https://ixtech.xyz/products/bitaxe-nerdaxe-gamma-whitepaper-edition?variant=46944522207490

But it's completely open source! you can 3D Print your own case and make them exactly as you want :)

How nobody in the bitcoin community really knows how mining works and how much centralized bitcoin mining is:

1. 80% of all miners produced are by a single chinese company that has violated GPL and installed backdoors into their mining firmware
2. 60-70% of all hashrate is controlled by two pools (Foundry & AntPoolFriends)

We're talking in Bitcoin always about open source, but mining is super far away from this. And especially the mega miners don't see a problem in that at all.
I'm pretty sure though if their shareholders actually would know that a megaminer is basically completely dependent on a single vendor that makes closed source software&hardware and with that creates a massive risk, they would demand change.

That is exactly what we are trying to solve at the 256Foundation: making a complete open source hardware and software mining stack, so that we can decentralize mining again.

not particularly, I'm a connoisseur of all memes.

If you want a specific one:

Probably not right now in the current bear market, but I know it will be hard again if we rip above $125k. I also stopped actually to convince people to buy, I learned if they are interested they will come and ask

I haven't read it myself, but I work with Tyler, Dylan and Mike together almost every day and they are some of the best educated and based heatpunks.
And I'm sure a lot of the ideas in there are shaped by discussions that I have with them or are happening on a broader scale at the Heatpunk Summit and other places.

It's a great tool and extremely important in our journey to convince home owners, trades people and investors that heat reuse, solar excess and off peak bitcoin mining is a massive opportunity.

Good question, not much. If you ask my wife and friends they will tell you that I'm a hopeless optimist :)

In the short term I am a bit worried about how the BIP110 discussion is ripping the Bitcoin community apart. We should fight together against Fiat and other forces that want bitcoin to go away. Instead of doing this we infight and actually help these other forces.
However in the long term bitcoin will survive this and actually come out stronger.

for the coming years yes, however if I look at the longer term I think the mega miners will slowly fade away and the hashrate be replaced by heat reuse projects (which includes home miners, but also schools, hospitals, district heating, etc.).

The reason for the megaminers to fade:

1. The reason that they currently make a profit is that there is missmatch between the cost to produce and the amount of miners existing. Over time there will be more and more miners on the network, this will push down the hashprice and will price out the ones that onlyl mine for profit, the ones that mine with heat reuse will survive
2. The mega miners all are pivoting to AI anyway, reducing the overall hashrate by mega miners.

I did a video with Staci where I share my opinion a little bit: https://www.youtube.com/watch?v=9CLQMWyTAL8

However I try to stay away from having too many opinions about stuff, for me it's more important that everyone decides for themselves what they want Bitcoin to become, if everyone does that Bitcoin will be the best system for humans.
Unfortunately a lot about the current BIP110 discussion is just focusing on generating a lot of fear, and usually with fear people can't make rational decisions (I was in the military and seen people taking stupid decisions when under fear). So I'm trying to explain people what BIP110 exactly is, how it works, what would happen if it activates today, etc. And then let the people decide themselves what they think is best for bitcoin.

If you want my raw opinion:

1. I don't like non-monetary data on Bitcoin
2. The way that Bitcoin is built we will always have non-monetary data in Bitcoin (same as we will always have illegals using the internet or the highway)
3. I believe over time the cost to add non-monetary data will make it go away
4. Any technical change to make it harder to put non-monetary data into Bitcoin is the wrong way to approach the problem and could also have unexpected consequences. We should rather focus our energy on making Bitcoin adoption wider, this will push non-monetary data away by itself (see point 3).

Simple: Declare your house as a Sauna and enjoy the sweat ;)

Otherwise:

• If it's an hydro/immersion system, get a dry cooler outside (basically a big radiator) and run the water out there to vent outside
• If it's an air cooled system, build a vent/duct to the outside

Start with a bitaxe, check out the Bitaxe vendor list: https://www.bitaxe.org/buy
It's the simplest and easiest to start with and gets you in contact with all things mining (flashing, pools, frequencies, firmware updates, heat usage, etc).

For heat reuse specifically there are multiple projects to learn. If you want to DIY check out:

• Slim19: https://github.com/SatStackingPleb/Slim19
• Stealthminer: https://github.com/PizzAndy/StealthMiner_V2 (also give https://x.com/Real_PizzAndy and https://x.com/SatStackingPleb a follow)

If you want something that is already built but still lets you take it apart and learn:

• https://256heat.com/collections/home-heating-kits

If you want something super slick:

• https://heatbit.com/
• https://www.solosatoshi.com/product-category/bitcoin-miners/canaan-avalon/

If you have some sats (or dollars) to spare, donate to https://www.256foundation.org/ which is also an 501(c)(3) nonprofit organization so you can tax deduct your donation.

Otherwise just help spread the word, on X, reddit, stackernews, etc. The more people know about open source mining, heat reuse, etc. the better.

And as soon as we have the first actual miners ready to install: Become a beta tester and give us feedback!

I had this idea (when shipping was cheaper) about renting heat miners during the Nth hemisphere summer. Sending it to Australia for 3-4 months during our winter.

yea, I thought about this as well. I've hard though that its just such a pain to ship the miners around that no many people do it.
I do wonder though if thats because the current miner hardware isn't really made for it, and now that we have open source hardware we could build miners that are much more rigid and made to be shipped around the world multiple times a year.

Do you think heating miners are worth pursuing in countries or climates that don't really get that cold.

yes, especially for heating water. Even in hot climates you need hot water: Shower, Dishes, Clothes, etc.
Obviously it will not that much heat than if you try to heat a house in a cold climate, but thats where open source is so important: being able to build a system that is made for the specific usecase.

Also in hotter climates you usually have a lot more sun and therefore also solar panels and with that free energy, which can be used again to heat water or just heat the air which will usually give you more money back than selling the energy back to the grid

Then when you fell you have reached a ceiling and want to do more find an S19J Pro somewhere, there are multiple vendors selling them in MOQ 1 (minimum order quantity. of 1). You should find them for around $150-$200
I'm getting mine from https://megaminer.market/ but there are also other sellers out there.

Oh, I got thousand of ideas :) But the one that I would love to work on but just don't have enough time right now:
Creating Cold through Absorption Chilling. Basically converting Heat back into Cold, which would allow a bitcoin miner not only to heat a house, but also cool it.
The technology is used already by Data Centers (massive scale) and RV-fridges running on Propane (small scale). However the heat that is generated by current Bitcoin miners is not hot enough for the existing absorption chillers.
So we either need to:
A) Figure out how to make the water that comes of from bitcoin miners hotter
B) Engineer an absorption chiller that can work with 80C water coming from the miners.
Probably in the end we will need to do both. But if we do, then we can basically replace any heat and cold source for houses and building by bitcoin miners.

1. Its built in a modern language: Rust
2. Its fully documented and architected for expansion and modification (existing open source pools are mostly built by single engineers and not very good documented)
3. It will support a lot of different payout schemas
4. Its built for big scale in mind (Proper Telemetry via Prometheus, etc.)

Thank you!

I do expect that eventually all houses will use bitcoin miners as their heat source, especially for electrical water heaters it just make so much sense to also use the generated heat for something else (generate sats).

However I'm also very aware that the current existing solutions are extremely steam-punky and will need a lot of work to be actually installed by people. Especially plumbers and HVAC tradespeole will need a lot of convincing.

As soon as the first products that are easy to use and easy to install exist on the market I could see a massive explosion of devices, who doesn't want a water heater that makes you money?

So I think there are a lot of hurdles to overcome, but we're working on them really hard with RY3T and 256Foundation. OpenSource is going to be the base for everything, and we are now so close to have a complete open source hardware and software mining rig.
