Blockchain Commons is working to advance the state of cryptocurrency wallets with interoperable specifications. We've got many different ongoing initiatives, so we recently produced a video to introduce them all. [1/14] https://www.youtube.com/watch?v=RYgOFSdUqWY

A lot of our focus is on responsible key management. We want to help wallet manufacturers to keep your crypto-keys secure and safe. So we talk about everything from good use of entropy (randomness) to adoption of multisigs and the use of airgaps. [2/14]

Multisigs are very important because they allow individual users to reduce Single Points of Failure and Compromise. [3/14] https://github.com/BlockchainCommons/Gordian/blob/master/Docs/Multisig.md

And airgaps are very important too, because they allow you to keep your keys separated from the network by a physical gap of air, which can be bridged using QR codes and cameras. [4/14]

Other foundational technologies that we use include CBOR encoding, CRC-32, SHA-256, Shamir's Secret Sharing, and fountain codes. It's a lot! That's why we put together the video. [5/14] https://www.youtube.com/watch?v=RYgOFSdUqWY#t=7m14s

Besides talking about foundational concepts, we also spotlight a few major technologies in our video. [6/14] https://www.youtube.com/watch?v=RYgOFSdUqWY#t=16m13s

The first is ByteWords. This is a way to encode binary data (such as cryptographic seeds) as easy-to-recognize, hard-to-confuse words. Bytewords are also well-integrated with QRs. [7/14] https://www.youtube.com/watch?v=RYgOFSdUqWY#t=16m21s

The second is Uniform Resources (URs). This is self-describing data that we present as an interoperable spec for transmitting data. It uses ByteWords and CBOR. [8/14] https://www.youtube.com/watch?v=RYgOFSdUqWY#t=19m58s

The third is Lifehash. This is a graphic method for recognizing seeds, keys, and other digital objects. [9/14] https://www.youtube.com/watch?v=RYgOFSdUqWY#t=24m55s

We've got tons more on all of these concepts, foundational specs, and technologies in that video! Take a look! [10/14] https://www.youtube.com/watch?v=RYgOFSdUqWY

We're also expanding our other docs to support developers interested in using our interoperable specifications. "URs: An Overview" looks at how URs are put together. [11/14] https://github.com/BlockchainCommons/crypto-commons/blob/master/Docs/ur-1-overview.md

"A Guide to Using URs for Key Material" demonstrates how to safely transmit seeds, HD Keys, and BIP-39 words. (There will be more UR docs to come!) [12/14] https://github.com/BlockchainCommons/crypto-commons/blob/master/Docs/ur-2-keys.md

Much of this work has been done with our Airgapped Wallet Community, who is helping us to prioritize real-world uses of interoperable technologies. [13/14] https://github.com/BlockchainCommons/Airgapped-Wallet-Community/discussions

The more support we have, the more we can do, and the less we have, the less we can do. If you'd like to support our increased work, consider becoming a GitHub patron. [14/14] https://github.com/sponsors/BlockchainCommons
