How do you share public and private keys among airgapped devices? I've made a video on how to export a cosigner from #LetheKit into Gordian Cosigner and then sign a PSBT. [1/6] https://t.co/FXKhAmZPwS

@Blockstream @Liquid_BTC Neat, this sort of looks like a #LetheKit I put together recently! https://t.co/vPSIZMqs1P I think it's great that you offer a DIY option, but I'm curious why you chose the @M5Stack Fire dev-kit instead of the m5stack dev-kit with the secure element? https://t.co/rO5eseV3LN

I finished hacking together another airgapped DIY #bitcoin hardware wallet, this time from @BlockchainComns @KenSedgwick @gorazdko It took all my skills from previous my DIY hww's, plus learning a new one 🪛🔥 Below are a compilation of photos of how I got there with the hw👇

@bitcoin_dna @nvk @SpecterWallet and #LetheKit require user entropy for all the 12 (24) words. The last word is amended by the device, but no entropy is lost. https://t.co/HMytdhHBq7

Order one if you want to support the project, its very valid, especially as a commercial tool...I'll focus on making a similar #lethekit type project for <$100

@NicolasDorier @dglab_official @bunniestudios Holy smokes! CC @ChristopherA @ksedgwic, this would make a lovely #lethekit https://t.co/Cci5vRNEtZ

If you are interested in seeing what #LetheKit, our cryptographic/airgapped/no-network/no-Bluetooth/no-storage/DIY device for creating seeds and deriving keys, offers for highest security of seeds, here is a video:

In adaptating the Specter Wallet’s approach for use in #LetheKit, https://t.co/1kFwjAx8Xc, I became concerned with the word “fix”, and both @gorazdko & I are concerned about using this trick for recovery process where the checksum is important.

Both @COLDCARDwallet @ #LetheKit from BlockchainCommons allow you use dice (preferably casino quality) to enter randomness, and use other tools to confirm results and generate last checksum word. ColdCard had a python app, and #LetheKit has a c++ app. https://t.co/0QFRu2bZL5

@vicariousdrama @StepanSnigirev @arcbtc Also, shameless shill😅check out some examples I made of existing DIY hww offerings here @DIYbitcoin Next up is @BlockchainComns DIY #lethekit https://t.co/Z3aQnkqktM and a DIY device from @Locha_io 🦾

@RussHarben We also support everything we do in #LetheKit with a separate c++ based command-line tool https://t.co/8mdwqlSS6u — you can verify that the same random dice generate the same keys, as well as test against (a hopefully offline) copy of Ian Coleman’s JavaScript tool.

I’m pleased to see Ken Sedgwick’s work on improving hardware & airgapped security for Bitcoin seed secrets now being applied to the Lightning Network. @ksedgwic was the designer of @BlockchainComns #Lethekit DIY airgapped seedtool that has a major new release this week.

LSP outlines many policies that HSMs could enforce when signing LN transactions. This makes it much harder for thieves to steal someone’s coins. Read about LSP in founders Ken Sedgwick (@ksedgwic) and devrandom’s (@devrandom01) own words here: https://t.co/5NOaqR1RZT 🌀

The @GordianWallet airgap architecture from @BlockchainCommons is coming together. With #LetheKit you can generate cryptographic master seeds using dice or hardware entropy (or restore them from cold) then output via QR seeds, sskr shards, xpubs or derived keys to other devices.

@GordianWallet @BlockchainComns Shamir Secret Key Recovery (SSKR): 3 shards split using #LetheKit & restored by @GordianWallet into a standard BIP39 mnemonic. In contrast to SLIP39 shards, SSKR shards can be converted in or from a BIP39 mnemonic words. Restoring either leads to the same HD wallet.

We are making good progress on a new standard that allows for airgapped PSBT signing between networked wallets, using animated QR with xpubs and non-networked devices with private keys. Key research item was limits on e-paper displays like #LetheKit uses. Great results @gorazdko!

almost 6 years ago

A major feature in the evolving UR standard for airgapped devices is the ability to convey large data such as PSBTs as an indefinite sequence of QR parts using Fountain Codes based on Luby Transform. I recently ran it on an e-paper display.

Someone shared with me recently a paper worksheet so that you could confirm your source of raw entropy (say dice) conversion the first 11 BIP39 words completely offline. But I've lost the bookmark someplace, and my twitter search isn't finding it. #SmartCustody #LetheKit
