OpenWallet Foundation: Meeting OWF Projects and Community Members
The OpenWallet Foundation (OWF) had a great Internet Identity Workshop (IIW) week in mid October, starting with our first hybrid Developer Face-to-Face (F2F) on October 9. The second half of the pre-IIW event was featured by an engaging and interactive workshop facilitated by Kaliya Young and Lucy Yang to get community inputs on the following topics (and created a Miro Board):
What Code / Components / Resources / Expertise do you have and/or know that can potentially be contributed to OWF?
What capabilities / code components / expertise would be ideal to support the success of OWF that are currently missing?
Internet Identity Workshop 37 Report 2023-10-22 Phil Windley
In closing circle someone said (paraphrashing) that authentication is solved and the next frontier is authorization. I tend to agree. We should have the book of proceedings completed in about a month and you'll be able to get the details of sessions there. You can view past Books of Proceedings here.

When asked how familiar they were with the concept of decentralized identity, half (49%) of consumers report no familiarity with decentralized identity, suggesting a need for further education about the topic among consumers. Familiarity of the concept, prior to taking the survey, is highest among consumers in Germany (28%), France (23%) and the UK (23%).
The Hype Cycle for Digital Identity, 2023, emphasizes innovations that facilitate secure and trusted digital interactions among people, machines, and assets based on digital representations of their physical and virtual identities, according to the report published on July 26.

[OWF] Application supporting interactions between flexible assets and the grid, adopted as a new project by OpenWallet Foundation 2023-10-23 EnergyWeb
Elia Group and Energy Web began collaborating on the design of a digital identity application based on a pre-existing specification: the verifiable credential application programming interface (VC API) specification. Their software enables signed identity documents (stored on digital wallets as verifiable credentials) to be exchanged between an individual’s digital wallet and a third party
Kim Cameron Award Recipients Share Their Experiences OpenID Foundation
The Kim Cameron Award paved the way to grow my knowledge in identity space and also allowed me to connect with a community of identity professionals. And also enabled me to meet OpenID Foundation members and also get to know the different working groups in person.

‘Identiful’ Digital Wallets and why you should care 2023-10-24 Digital ID NZ
alongside specifically purposed private sector wallets we may see the public sector in some jurisdictions taking a role in aspects of their development – be it interoperable open standards and code libraries or a completely built digital wallet – for its people. This demo from global thought leaders the Province of British Columbia peeks into the possible future
Education Credentials on EBSI: Cross-Border Use Case between Belgium and Italy 2023-02-01 Evrim Tan, Ellen Lerouge, Jan Du Caju, Daniël Du Seuil
The findings highlight the following as key challenges for the wider adoption of the EBSI and verification credential use case: (1) onboarding of the EBSI ecosystem governance, (2) issuance of EBSI-compliant digital wallets and data schemes for transcript validation, (3) interoperability issues concerning digital identity systems.
Selective Disclosure: An EBSI Improvement Proposal 2023-10-27 EU Commission
Right now, an EBIP on Selective Disclosure is open for public feedback. Whether you're a developer, researcher, standardisation body, node operator, EBSI Early Adopter, or a blockchain enthusiast, your insights and contributions matter.

The BBS Signature Scheme 2023-10-23 CFRG
the possessor of a signature is able to generate proofs that selectively disclose subsets of the originally signed set of messages, whilst preserving the verifiable authenticity and integrity of the messages. Furthermore, these proofs are said to be zero-knowledge in nature as they do not reveal the underlying signature; instead, what they reveal is a proof of knowledge of the undisclosed signature
Moving Beyond the Limitations of did:web Markus Sabadello (Danube Tech), Alex Tweeddale (cheqd), Carsten Stöcker (Spherity GmbH), Alen Horvat (Netis)
These core issues run deep, to the point where did:web is beginning to falsely represent the true value and core purpose of DIDs, since the DIDs are not decentralised, cryptographically verifiable, tamper resistant, self-certifiable or persistently stored.

[Japanese] [Hyperledger Aries] Try issuing and verifying LDP-VC with did:web 2023-10-07 One Tech Blog
In my work so far , I have used did:sov, which is based on the Indy Ledger, for issuers to sign AnonCreds and LDP-VC. In this article , I will share the results of trying to issue and verify LDP-VC using did:web without using Indy Ledger . (Cryptographic Suite is being tested on both Ed25519Signature2018 and BBS+ Signature (BbsBlsSignature2020).)

Using Open Recognition to Map Real-World Skills and Attributes 2023-10-25 We are Open CoOp
We see a need for a platform that aids individuals in identifying their skills and attributes, supported by their networks and communities. Mapping these attributes against relevant skills taxonomies can make them visible and endorsable, turning them into a form of ‘currency’ [...] We’ve come up with the following workflow (v0.1) to show how that might work technically, and below that there are wireframes showing a basic user journey.
Guest Blog: .zkdid 2023-10-25 Decentralized Identity Foundation
Toby came to DICE in Zurich and found his tribe!
Each address with the .zkdid extension is a unique identifier in the form of a Non-Fungible Token (NFT) which is resistant to duplication. The goal is to use these identifiers to create a ZK Proof of personhood registry and NFT-gated community that is Sybil resistant. [...] This creates the basis for a secure, publicly owned/governed, decentralized, zero-knowledge Domain Name System (DNS).
This prestigious appointment demonstrates IdRamp’s expertise in advisory, implementation, integration, and managed services for delivering secure and seamless solutions using Microsoft (MS) Entra Verified ID.
“The integration of Verida’s decentralised identity storage wallet with the cheqd network offers a compelling vision of ‘Not your keys, not your identity’. People’s digital selves should be in their control, and this includes being able to store their credentials outside of the control of Big Tech providers,” says Ankur Banerjee, CTO and Co-Founder at cheqd.

[Inrupt, PDS] Same words, opposite meanings. Beware! 2023-10-24 Alan Mitchell
Yes. That’s right. With Inrupt’s definition, a personal data store is no longer your private, personal filing cabinet, but the organisation’s filing cabinet: “a place for organizations to merge all the data they have about an individual citizen or customer”.
