Paradigme Bitcoin in Switzerland 🇨🇭 5th edition \ stacker news

It was the 5th edition of Paradigme Bitcoin, a conference centered around Bitcoin in Neuchatel, Switzerland mostly in French. I found the atmospher...

Recently I've come across a number of "security"/"educational" web apps that invite you to enter your seed phrase into a webpage — honestly, this is insane! 🤯 Generally, these services are targeted at security-minded users and feature a big warning telling you to turn off internet to stay safe. Here's how it could go wrong: - A malware could be recording keystrokes for later harvesting. - The webpage could be recording the seed phrase for later harvesting. - A third-party analytics script could be recording keystrokes for later harvesting (some of these pages actually embed Google Analytics!!) 👀 - A hardware keylogger could be recording your keystrokes for later harvesting. The general rule is simple: if you use a hardware wallet, never *ever* enter the seed phrase on a general computer; you'd be degrading your security to the level of a software wallet, defeating the point. And if you need to generate or split a seed phrase without compromising on security, Penlock is there for you. 🛡️

🇨🇭 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 👋 🔗 Full program:

Home sweet home! Penlock is now available to buy at the @Bitcoin House Bali 🏝️... I guess we've come full circle!

Thank you Emily for the sleek design, everyone loves it! View quoted note →

@npub12egc...7243 now ships Penlock kits individually to the US, Canada, Mexico, Western Europe, Thailand, and Japan! You can find them here:

Seed Keys

Penlock: Offline Tool to Generate, Split, and Recover Seed Phrases

Discover Penlock, the paper-based tool to generate seed phrases, split them into 2-of-3 backups, and recover them offline using proven cryptography.

Also, check out their metal backup — it's definitely one of the best 24-word metal backups on the market! You can store your Penlock shares on it by using an electric engraver instead of stamping. Can't wait for a 12-word version that's fully Penlock compatible! There's also a shipping option in South Korea, thanks to @Coconut. : https://store.btcmap.kr/stores/powbitcoiner/ Meanwhile, we're busy setting up our own Geyser shop, where you'll find kits in bulk (packs of 10 and 50), as well as private support, consulting, and more!

Huge thanks to @AnnieV and @Miss ₿anks 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 @₽sy𝑓er for setting this up — definitely inspiring me to create more video content in the future. Stay tuned!

We're live at https://meet.fulmo.org/cmhonline ! Join us for an online Penlock workshop with London's Munks!

🔥 Saturday 28th at 10am UTC, Penlock and @CYPHERMUNK HOUSE | LONDON will host an *online* workshop on how to improve your self‑custody with Penlock! 🔐✨ Learn how to turn a seed phrase into a 2‑of‑3 backup for higher security, offsite recovery, and trust‑minimized inheritance. The workshop will be interactive! If you got your Penlock kit at the Munkfest (courtesy of @Angor ) or anywhere else, please cut the tiles before the event and have the other components ready. When cutting, fold along the cutlines before detaching — these are a bit rough. Alternatively, you can print & assemble the wheel, the tiles and the wordlist from the components list at

Penlock / Split a Seed Phrase

Split your seed phrase into a 2-of-3 backup using Penlock

, and the sumtable from

Penlock / Recover a Seed Phrase

Recover a seed phrase by combining 2 Penlock shares belonging to the same set.

. Or just come and listen! Everybody's welcome :) View quoted note →

Here are a few shots from the Penlock workshop at the Australian @bitcoinbushbash 10 days ago, where some kits were given for free. We heard the feedback was extremely positive — great job, friends! View quoted note →

Here's our new Nostr banner by @emily , designed to match the kit's visuals! How do you like it?

We successfully test-delivered Penlock to 4 different countries! This confirms logistics are sound. The next step is to finalize & launch the shop, along with a visual update for the website & socials. Penlock kits are now available to buy at some of our partners’ & friends’ Bitcoin spaces! Namely: @BOBSpace_BKK (Bangkok, Thailand), Bitcoin Center Seoul (Seoul, Korea), and Base21 (Busan, Korea)

🇰🇷 Keating (@btclog29 on X) released a series of Korean videos about Penlock! It includes a thorough introduction as well as how-tos for all 3 Penlock features. Thank you for creating and sharing this! ✨ 🤔 What is Penlock and why is it needed: ✏️ Generate a seed phrase with pen & paper: ✂️ Split a seed phrase: 🔑 Recover a seed phrase: ⚠️ Reminder: Always use the official guides when dealing with real funds.

We commissioned @Tynka to create this lovely illustration of her going through the process of generating a seed phrase by hand using Penlock! 🎨 You can try it yourself at

Penlock / Generate a Seed Phrase

Generate a new 12-word seed phrase using real-world, provable randomness.

— all you need is a printer 🖨️ and a pair of scissors ✂️. The whole process, including learning and assembly, takes less than 30 minutes. Thank you, Tynka! 🙏

Sydney Bitdev ran the first independent Penlock workshop we've heard of! 🇦🇺⚡ The feedback was super positive, and it's very exciting to see Penlock taking on a life of its own! Apparently they'll bring it to the next @bitcoinbushbash . If you're in Australia, you can check the event at:

. Would definitely love to be there in person, the vibe seems awesome! 😎 View quoted note →

Thank you @BOBSpace_BKK for hosting our workshops! 🙏 The room was pretty full, and the lightning market is really cool with all the stalls, the lights... and even a live band! 🎶 Such a great monthly event – definitely recommended if you're in Bangkok near the end of the month. For the curious, recap by @npub12egc...7243 just below 👇 View quoted note →

Thanks for the cool pictures! See you around the world :) View quoted note →

I'll run an additional workshop in Bangkok for @SatoshiSquareBangkok , on the 2nd of March. Everyone's welcome, and attendees will receive the brand new kits! 🙌 (as well as in Bob's one on the 27th :)) Link:

🏭 Production is complete, we did it! About 2,900 kits have been sent to our storage in Jinhua and are ready to ship, with 100 more already in my hands for quality control and the workshops in Bangkok. 📦 Next step: I will run a few test deliveries to our partners and contributors to ensure the logistics are running smoothly. Once that's confirmed, our not-for-profit shop will be ready to launch! Target date... March 21! 🚀

We'll have two events about self-custody this month at @BOBSpace_BKK (Bangkok) in collaboration with @npub12egc...7243 metal backup. Since we're having all these new products on the self-custody market, it's becoming difficult to identify the trade-offs at play. We'll dig into that on the 13th through a new presentation put together for the occasion! And on the 27th we'll run our workshops, hopefully featuring the brand new Penlock kits! View quoted note →
