I understand and you’re correct for bitcoiners. But for the majority of people verifying something on a different screen is already to difficult. Especially a bitcoin address. I can imagine that people actually just buy these devices to sign transactions and save their bitcoin that’s it. No physical backups, just two of these devices with the same keys synced. They’re fingerprint protected so they’ll just lay them in two separate locations. If this syncing would be possible I’m curious if they would be able to this device to device via bluetooth for instance. You wouldn’t want the keys to touch the phone.

The first reason you need a cold storage device is because you want a private key generator that you can trust. Second reason is because you need something to get bitcoin off the exchanges. How do we achieve this easily for the masses?

Without users, there’s no one to built for. What you share might inspire others to build, for Nostr or bitcoin… by your inspiration and humor you revive other builders. You are working on Nostr, not by physically coding but by inspiring people and being here. Giving a quick laugh being out of the continuous grind can up productivity 😉

On boarding a lot of people with a lot of different hardware wallets/signing devices I would like to take a stance for this solution. Most people don’t self custody because it’s to difficult. So how can we get them to easily and cheaply self custody?

The most sold device on planet earth is a closed source, data leaking, chainalysis cooperating low quality, physically connected to the internet, shitcoining ledger.

Would an open source, air gapped cheaper, bitcoin only and more intuitive wallet be an improvement as first step? I believe it is.

In Antwerp there is an amazing Vietnamese restaurant called BUN. Yesterday we ate there with friends. These friends I’ve known almost since I was born. It’s a diverse group all coming from the same rural town I grew up and now again live in. Some believe in bitcoin some are fiercely against it. Paying the restaurant yesterday with bitcoin (€850,- in two parts via lightning fyi) was an eye opener for all, though I don’t know if they will remember as the alcohol tasted great. I’m the only one that doesn’t drink 😊

Because these e-bikes are rented out for long distances almost every day, it made sense in comparison with cars FI. But the cycling was mostly for leasure, so again an additional waste of resources in comparison with renting a traditional bike. Fact, most people want comfort and are too lazy to be on a normal bike. Comfort creates waste and reduces personal physical proof of work.

Your point that you flew to the conference because you find it important is the exact ethical question everyone should ask themselves. Do i waste more resources and pollute our spaceship earth for future generations or not? Is it worth it?

Most people have no clue of the actual impact. So the only way to go about this is education and less free money on credit. When the cheap financing of all the junk e-bikes on payment plans for people stop, less will be bought. At least we would see less waste in the Netherlands because government incentives gave almost everyone an e-bike with a payment plan that was extremely cheap. Now everyone is on an e-bike while before the people were on traditional bikes. A huge nett negative for the environment… FYI. Picture below of the fire safe concrete battery charging vault I designed and built back then. Fully charged with solar.

E-Bikes are actually a lot worse for the environment than bikes. Had to calculate this when I started a bike rental a few years ago. Especially when the bikes stand still most of the time it’s actually a huge waste of resources. Classic bikes without motor and battery are >10x better for the environment. So if you’re an environmentalist you don’t promote e-bikes but bikes. My proof of e bicycle work 😊👇

When we use the heat of renewables and use less natural gas where we used to heat with previously, it’s actually “carbon negative”. I’m not the bean country type of guy but it at least got mainstream attention at CNN and AFP. This is what we build out throughout last year: examples that could be shared publicly: greenhouse, warehouse. But there were also a restaurant, offices, lumber workshop etc etc.

Because “climate” is an extremely hot topic in Europe we’re focusing on “carbon negative” mining solutions. Fact is, that it’s the only way to mine profitably in Europe. You need to

-use the heat

-have large scale consumption

-input excess electricity from renewables.

Ticking all three boxes is even better.

The reason large corporations like Facebook and Google are in the Netherlands is due to extremely cheap electricity for large consumers. No tax for them while there’s a high tax for the general population (>50% over energy). When the natural gas prices soared, the population paid the bill to compensate the long term contracts for the large corporate consumers.

Because the population saw prices of far over €1,- per kWh almost everyone started to install solar. Yesterday and today this already resulted in negative prices on grid electricity. Our transformers at the solar setups shut down, due to overload on the grid. If you can’t use all electricity you produce, you physically can’t deliver it on the grid anymore. The first projects where we mine away the overcapacity at small farms are starting this summer. There is not much choice, it’s either mine it or find another way to consume it directly. And these farmers don’t have another way to consume it directly. Netherlands will become a distributed bitcoin mining heaven with all this insanely rapid build out overcapacity of renewables in a contracting economy. If we would use Google, Facebook and other corporations less the national consumption of electricity would actually drop significantly. The question now is, what is more important? Financial sovereignty or a viral cat? Free market decides. The cats will keep on winning until the true price of the viral cat starts to be paid. I believe that time might be more near than we think.

Hope everyone stays safe. The necessity of using a different monetary protocol as a base layer becomes ever more important.

Any live report on the riots in France on Nostr? Hearing they cut the internet in Paris and Toulouse. Must be some guys with starlink there right?

Because my wife is almost giving birth we couldn’t attend. But this is a summary which makes you feel like you are there. The highlight for Arnold was clear in the article. Watching it I can feel why. https://youtu.be/B6YQQC5Q_5g?t=10140

Grabbed the one next to it, now posted it below as the gif. Can’t delete the post once broadcasted to relays 🤦‍♂️

Bitcoin is the only physically verifiable money on our planet accessible for all humans. It is a uniform physical state of millions of transistors distributed across the globe. Easy to trust and verify for any human being. It’s just so young people don’t understand it yet.

Below I created a gif of the Turing machine. Physical state machine aka a computer these days. Don’t forget computers are physical transistors. Bitcoin is physical.

When you see this many 9s what does it mean?

Being in Europe I would say we prefer to stay neutral. Especially in Switzerland and the Netherlands who through history always tried to remain neutral. Netherlands managed neutrality in ww1 but was invaded in ww2 despite the neutrality efforts.

The best way for these two countries to show neutrality again is to speed up bitcoin adoption. Switzerland is currently far ahead in this race.

Today I wrote a directional part of a longer article to be published in German later this year. Please let me know what other direction you would like me to highlight:

“Banks collapse, but the currency will live on. A currency only collapses when the trust in it is eroded. Currently people don’t trust bitcoin. Bitcoin is polluting our planet. That’s what people think. So how do we counter this thought directly?

Bitcoin mining is positive for the environment and ensures cheap electricity for everyone. And it’s not just because fiat money pollutes and bitcoin reduces pollution. It’s not just that every euro in bitcoin is otherwise spent to pollute more. Bitcoin mining by itself is ensuring a better environment.

Miners are searching for the cheapest electricity across the globe. Cheapest electricity can always be found where it is in excess. In these locations there are mostly two reasons excess energy is available. Either an energy source is already being used to generate electricity but not used to its full potential or there is potential long term untapped abundant energy resources available that haven’t found sufficient demand yet.

Because we are positioned in the EU and demand for cheap electricity is almost everywhere we shall focus on the first reason. In Europe currently there is no sufficient cheap electricity available. Due to natural gas deliveries being made impossible. Because of this, build out of renewable generation and nuclear is sped up in multiple locations across the continent. The countries where renewable energy is now being propelled, excess unstable energy will become abundantly available. If we think we can consume this excess flexibly easily, you haven’t studied physics. The grid that has the highest percentage of renewable generation on our planet is situated in Texas. To balance the grid they are already using miners.

In Europe this will move into a similar direction, the difference is: we would still be able to capture the heat that is produced.

Heat is important during our winter, if we are able to capture the heat produced by miners we could facilitate the ultimate solution.

Currently we are heating business and greenhouses with excess energy in the Netherlands. The miners blow heat directly into the greenhouse or business. The greenhouse needs heat 365 days per year, half of the year for growing, the other half of the year for drying tulip bulbs.

For the other locations the heat can’t be used year round. But the peak of overcapacity in their renewable generation is not during the time the heat is needed.

The next logical step is using geothermal capture in combination with bitcoin mining. Miners use the excess renewable generation and heat is stored to be used when we need it.

For now we keep businesses warm and grow plants in greenhouses, but for the future you would like to use heat capture technology.

In the Netherlands using bitcoin is already the best thing you can do for the environment. When we have locations that capture heat we can further optimize our energy expenditure.

When this is efficiently working, renewable projects can more easily be built. Current grid capacity is not able to deal with high peaks. Being able to tune frequency or even stop mining when there is no sun or wind would make many projects complete. In combination with geothermal heat capture the opportunities are endless. Not just growing food in greenhouses year round. But also heating up a citadel that is self sufficient and literally living on a bitcoin standard. “
