Print & assemble Penlock's cryptographic wheel to split your seed phrase into a secure 2-of-3 backup. Protect against loss, theft, and enable secure inheritance
Penlock got covered in @jimmysong’s Bitcoin Tech Talk! ✨ This is a high-signal newsletter that always comes with some food for thought… I don't know how he keeps up with reading so much, year after year! Here’s what he had to say about Penlock: β€œIf you want to back up a seed phrase but don’t 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.” Well, looks like we’re on the same page… more news about it soon! πŸ“° Bitcoin Tech Talk: πŸ“Œ We were featured in:
We're excited to welcome our second sponsor: @Coconut. ! πŸ₯₯ 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 πŸ‘₯. 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! ✨ You can find them at and ... Or, meet there in person? πŸ“
We're thrilled to announce our first sponsor: Angor! πŸŽ‰ @Angor is a P2P crowdfunding protocol built on Bitcoin and Nostr⚑. 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! 🀝 You can find them at . A V2 is coming soonβ€”we definitely advise checking that one out! πŸ‘€ #bitcoin #penlock #angor
πŸŽ‰ Our campaign to bootstrap a not-for-profit Penlock shop was a success! We raised 0.07 BTC – almost double our goal! A huge thank you to everyone who contributed and reposted. A special thanks to our two main backers – we're excited to announce our sponsors soon!
