Last July, @WolfMcNally and I laid out the Universal Resources (UR) specification, a method for encoding binary data in plain text strings that are also well-formed URIs. [1/6]

Why another data format? Because we wanted to resolve interoperability issues that were affecting the Bitcoin space, and to expand the capabilities of QR codes. [2/6] https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2020-005-ur.md

The most exciting application so far has been the creation of animated QR codes, allowing for the reliable transmission of PSBTs to airgapped devices for the first time. [3/6]

We've also enjoyed great partnerships from companies like @FOUNDATIONdvcs and @SparrowWallet who have ported our reference UR libraries and are adopting UR codes into their own products. [4/6] https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2020-005-ur.md#implementations

Other companies like @CoboVault and @BlueWalletio and other #bitcoin wallet companies have announced plans to support animated QRs for PSBTs using this UR specification. [5/6]

If you are a wallet developer interested in supporting animated QRs for PSBTs as well as other cryptographic objects, or wish to support other interoperability standards like #TorGap, join the Airgapped Wallet Community hosted by @BlockchainComns.
