Last Notes npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock I think it's a question for a lawyer. Each state and country will have their own answer, and it's likely going to be something convoluted. To add to the complexity, no ones forces you to incorporate in the state you live in. npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock It's exactly the same as accepting Bitcoin donations. npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock 🇨🇭 Taz will host the very first Penlock workshop in French on June 26th at Le Paradigme Bitcoin in Neuchâtel, Switzerland! Feel free to drop by and say hi 👋 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Let's goooo!! npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Thanks! Looks like @nprofile…h0j2 did a good job. We need to find a way to protect the corners. 🤔 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Not yet! I'm planning to record it after I'm done dealing with more urgent matters. Probably next month, I'll publish it on Nostr. :) npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Thank you Emily for the sleek design, everyone loves it! #nevent1q…s0xf npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock You're welcome! Saying this just in case: please mind that the checksum holds sensitive data, and share 3's encrypted checksum can be combined with share 2 or share 1 to try to guess the original phrase. npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock @nprofile…h0j2 now ships Penlock kits individually to the US, Canada, Mexico, Western Europe, Thailand, and Japan! You can find them here: https://seedkeys.xyz/product/penlock/ npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Agreed. Humanly, there's always a limit. npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock I got that card too! 😎 npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock I think it works as follows: society not being made of self-sovereign peers cascades into situations that strongly prompt us to build more self-sovereignty. The only unknown is: how far does it need to go before enough people wake up and start taking matters into their own hands? npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock For the record they've long been know to check entrants social media, take them apart and question them if they find anything they dislike. So it's in the "make it legal & systematic" box, not entirely a new thing. (unfortunately) npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock Huge thanks to @nprofile…fvna and @nprofile…cwyz for hosting the workshop, and to the Munks for coming! Despite a microphone failure and some early connectivity issues, we still managed to run a great interactive session. Also, thanks to @nprofile…wv5v for setting this up — definitely inspiring me to create more video content in the future.

I don’t think I need a Codex32 one, to be honest — it looks great though! You might want to mention it on the Codex32 GitHub; they’ll definitely be interested in it! npub1xlhmmmtmmk0v3l5heafjf4ktjqavhqwnkw455cnljettdamrzr3smlzcqv Penlock There has been some demand for something like this, so I'm going to consider it.
