Blockchain Commons LetheKit SeedtoolLatest release: 0.5.0 ( 7th October 2021 ) 🔍 Last analysed 29th April 2022 . Do-It-Yourself Project
This project is not meant for non-technical end users.
As part of our Methodology, we ask:
Is the product meant to be ready for use "out of the box"?If the answer is "no", we mark it as "Do-It-Yourself Project".
Many hardware wallet projects aim to be as transparent as possible by using only off-the-shelf hardware with an open design and open code. If the product reviewed is not available in an assembled form - if the user has to source his own hardware to then maybe solder and compile software to install on the device it falls into this category.
Help spread awareness for build reproducibility
Please help us spread the word discussing build reproducibility with Blockchain Commons LetheKit Seedtool via their Twitter!
Do your own research!
Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.
The Analysis ¶
LetheKit is a do-it-youself platform for performing various sensitive cryptographic operations on an offline airgapped device. It uses no WiFi or Bluetooth which could leak information and contains no local storage, and when the device is turned off it forgets any sensitive data stored in RAM. Thus the name Lethe (lee-thee), from the mythological river of forgetfulness and oblivion.
Users can roll a physical dice or generate hardware entropy to create truly random seeds
Gordian LetheKit is a hardware exemplar meant to display the Gordian Principles, which are philosophical and technical underpinnings to Blockchain Commons’ Gordian technology. This includes:
- Independence. LetheKit ensures that you’re in total control of your seeds.
- Privacy. LetheKit is totally offline.
- Resilience. LetheKit depends on you for its resilience, since you must back up your words or codes.
- Openness. LetheKit communicates through airgaps via URs and QRs, for maximum interoperability.
The Blockchain Commons LetheKit Seedtool is in late alpha development stage. As a DIY device, it can perform the following functions:
- Display the seed in UR, QR code, or text.
- The seed can also be converted into BIP39 words.
- Construct HD-keys to view them on another wallet.
- It is also possible to view bitcoin address derived from mnemonic seeds with BIP32.
- Wallet descriptors can be exported to another device.
