We'll have two events about self-custody this month at @BOBSpace_BKK (Bangkok) in collaboration with @Seed Keys 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 β

Penlock is a tool to manually create a robust 2-of-3 backup of any seed phrase. It strengthens your self-custody setup, securing offsite recovery and inheritance without dependence on any third party.
Production update: We recently launched the production of 2,500 English and 500 Korean Penlock kits! π οΈ Delivery is targeted for February 10. π

This completes phase 2 of our Angor campaign, and we claimed the 0.019BTC milestone reward. We are now focused on setting up logistics and the online shop interface.

Penlock got covered in @jimmysongβs Bitcoin Tech Talk! β¨
This is a high-signal newsletter that always comes with some food for thoughtβ¦ I don't know how he keeps up with reading so much, year after year! Hereβs what he had to say about Penlock:
βIf you want to back up a seed phrase but donβt want the seed phrase in a single place, this is a very interesting option. The main idea is to split a 12-word seed phrase into a 2-of-3 backup, but instead of using a computer to split this up, it uses a printable paper wheel. It uses some clever cryptography under the hood and what you end up with in your shares are other seed phrases that can get combined to recover your 12-word seed. Honestly, the makers should make these wheels available for sale as it mitigates the evil maid attack.β
Well, looks like weβre on the same pageβ¦ more news about it soon!

We're excited to welcome our second sponsor: @Coconut. ! π₯₯
The @Coconut. team is building two mobile apps that work in tandem: Coconut Wallet, a watch-only Bitcoin wallet, and Coconut Vault, an offline signing app designed to run on fully isolated devices. Beyond software, they operate the recently opened Bitcoin Center Seoul to support education and community development π₯.
We first connected at a Bitcoin public event in a Korean university, where their CEO took the stage as the MC. The vibe of a nearly-full amphitheater studying the potential of Bitcoin was really something else! β¨

We're thrilled to announce our first sponsor: Angor! π
@Angor is a P2P crowdfunding protocol built on Bitcoin and Nostrβ‘. It leverages smart contracts to provide a fully non-custodial solution, using Nostr as its only back-end.
We've been in touch with the @Angor team since Penlock's pre-release in Bali. In fact, the not-for-profit Penlock shop was largely inspired by our conversations about aligning incentives between open-source projects and their backers. The team has a great "build forward" mindset and has consistently supported the community, so we're really glad to feature them on our kits! π€
You can find them at . A V2 is coming soonβwe definitely advise checking that one out! π
