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.
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.

- Getting Started with Self-Sovereign Identity SSI
Webinar | Multiple dates
In this webinar series, Condatis experts in decentralized identity focus on SSI use cases and solutions to real business problems. Join our upcoming webinar on 17 February at 3 pm GMT.
- Jolocom has been working on a Rust implementation of DIDComm v2 – check out the library on their GitHub.
- The Identity Working Group at INATBA recently published a position paper on decentralized identity written by practitioners from the community with Jolocom’s Kai Wagner as lead author.
eSSIF LAB (EU) - Infrastructure-Oriented call
- Infrastructure-Oriented open Call, with grants of up to 155 000 € (9 months projects).
- The call is open to European innovators and focuses on the development and interop testing of open-source SSI components.
- Some examples of SSI components include Wallets, server proxies, revocation, cryptographic enforcer policies, integration, interoperability, compatibility, just to name a few.
- Please note the final-round deadline: ** 30 June 2021, 13:00 CET** (Brussels local time).
- Apply here
NGI Open Calls (EU)
- Funding is allocated to projects using short research cycles targeting the most promising ideas. Each of the selected projects pursues its own objectives, while the NGI RIAs provide the program logic and vision, technical support, coaching and mentoring, to ensure that projects contribute towards a significant advancement of research and innovation in the NGI initiative.
- The focus is on advanced concepts and technologies that link to relevant use cases, and that can have an impact on the market and society overall. Applications and services that innovate without a research component are not covered by this model.
- Varying amounts of funding

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.”
