🚀 DIF monthly #15

February, 2021

Welcome to the 2021 February issue of DIF Monthly, the monthly newsletter of Decentralized Identity Foundation! Read below for the latest updates on the work of the decentralized identity community every month.

Foundation News

DIF F2F Virtual

DIF held its semiannual “Face-to-Face” community’ event in January, and man, what an event it was! For obvious reasons, it was virtual for the second time, and for the first time, it spanned both Zoom and the interactive social platform gather.town, giving a more intimate atmosphere and allowing for more organic networking than often happens at “teleconferences.” If you missed it in part or in full, you can find high-level summaries and recordings of the main events on our blog.

New work items in DIF:
DIDcomm Bluetooth work item officially kicks off under DIDcomm WG

  • a specification that describes general-purpose discovery and transport mechanics over Bluetooth for DIDcomm

VC Marketplace work item kicks off under CC WG:

  • to establish the reference architecture for a Verifiable Credentials Marketplace,

Credential Manifest work item rebooted under CC WG:

  • the format that normalizes the explicit definition of issuance requirements and contents to unknown recipients and verifiers

Wallet Security Working Group (preapproved)
The WG will design and define secure wallet architecture, establish common terminology, produce guidelines, classify and specify security capabilities and best practices, and more.
If you are interested to learn more about the group, join the mailing list

Trinsic donates did-key.rs to I&D WG
by Decentralized Identity Foundation | Medium

“The newest donation to the I&D WG archive is an implementation of did:key built in the Rust language by long-time active DIF members, Trinsic. In addition to being great news for the I&D WG itself, it is also great news for the “target audience” of the WG: developers trying to smoothly and efficiently extend the domain of DID-based systems to new programming languages, use cases, and contexts.”
