Unbacked Lightning channels proposal – how to scale, increase capital efficiency and interoperability of Lightning

I believe in order to improve lightning network, we should allow for unbacked channels between nodes of the same owners (operators). It would enable a few very interesting use-cases, without causing inflation or any other risk to other parts of the network. Unbacked channels increase capital efficiency, availability and help in growing the network by […]

Bitcoin censorship will most likely come, pt 2

In my previous article, I explained why I think Bitcoin censorship is coming without majority of miners being forced to censor transactions. I am pleased with the discussions it brought and I would like to clarify some points. Before you choose to discuss, please read the original article and this article. I know it is […]

How could regulators successfully introduce Bitcoin censorship and other dystopias

Note: A lot of people think this is purely about >50% attack. Not true, here’s how this unfolds with 10% of censoring hashrate. Bitcoin is often said to be anonymous and uncensorable. Thanks to chain analysis, anonymity is to some extent a disputed wishful thinking from the past. And it looks like it won’t be […]

Interview with GPT-3 about freedom, optionality, TAZs and Bitcoin

Tell me the baboon story from Robert Sapolsky. When Robert was studying baboons, there was an outbreak of a virus that affected the hippocampus region of the brain, causing animals to go insane.

Parallel energy production – solar panels are not rocket science

I started playing with solar energy, see a simple overview of the energy production and storage system in this video I made: So far, I thought that solar energy was demanding – it needed specialized experts to install it and make it work, complicated technologies that I don’t understand, drilling into walls and so on. […]

Privacy enhanced webtorrent client

I like WebTorrent especially for movies, because you can watch immediately without waiting for the torrent to finish downloading. My fork adds leech mode to stop upload right after download finishes, does not send telemetry and a few other changes. Actually, WebTorrent has a lot more features. You can download directly in a web app, […]

Crypto lifestyle using Bitmex and my scripts

Update: As of August 2020, Bitmex introduced KYC, so I switched to Deribit. This strategy still works on Deribit, I will also update my scripts. Sometimes you want to keep USD value of your Bitcoin, for example if you know you will have future expenses with known USD value. If you don’t want to go […]

Migrate virtual machines using LVM without access to hypervisor

I decided to migrate a few virtual machines from one hosting service to another. Most other howtos either recommend a reinstall or need access to the hypervisor (KVM/libvirt in this case – I could use native migrate functionality), which I did not have. Of course, you need to make sure you have the same architecture […]
