Lionel Wolberger: I'm interested in Veres One working session? [scribe assist by Manu Sporny] Heather Vescent: Kim - I can totally make [School House Rock for VCs and DIDs] happen, just need some funding and have some convos. Drummond Reed: There was a Sovrin discussion, overview, along with the DID methods under development. ...

In addition to the usual philosophy and high level discussion, there was detailed discussion of DIDs, CCG, self-sovereign identity Nathan George: There were many interesting sessions with reasonable notes (one example http://iiw.idcommons.net/User-Controlled_GDPR_Consent_Cookie) ... ChrisA polled the room to see if this was "NOT" reasonable, and Joe was pleased to see half the number of responses ... There are some "anti-" and skeptical folks, who don't see how blockchain is a practical solution ... but the overall indication was real engagement and positive reactions, traction, to the proposed uses of Blockchain that we are discussing Joe Andrieu: Point of clarification: the Verifiable CLaims Working Group is a different group Topic: Verifiable Claims WG Meeting Manu Sporny: Meeting minutes for VCWG: https://lists.w3.org/Archives/Public/public-vc-wg/2018Apr/0010.html Manu Sporny: Minutes themselves: https://www.w3.org/2018/04/06-vcwg-minutes.html Manu Sporny: We had good attendance-- a good sign .... extensibility was highlighted and we understand now that we need to clarify this ... clarify how Sovrin does its proofs, and signatures do that in credentials and DIDs ... Did Auth discussions at IIW ... interesting ideas about hardware-backed keys participating in signature generation Dave Longley: (And doing it on the Web) Dave Longley: (Web API) ... critical for high stakes/high value transactions, e.g. high cost governmental interactions ... W3C extended their hands and were interested in contributing in order to add that layer of security ... solid progress overall ... some more subtle issues surrounding philosophy and design really benefited from the face to face time Manu Sporny: VCWG face to face issue tracker: https://github.com/w3c/vc-data-model/issues Drummond Reed: +1 To Manu's point that there was great progress in seeing a path for how Sovrin verifiable credentials that use ZKP can fit within the standard definition of VCs that the WG is creating. Joe Andrieu: Face to faces are extremely valuable for the subtle work. So hey, get on a train/plane/bus and come on over! Drummond Reed: +1 To Joe's point about how much progress can be made at F2F meetings. Joe Andrieu: Next TPAC with expected big push... Lionel Wolberger: Face to face -- there are other venues. Is Consensus in NYC going to attract DID folks? [scribe assist by Manu Sporny] Lionel Wolberger: Who is attending Consensus in May, NYC Manu Sporny: Veres One won't be at Consensus. Manu Sporny: Sherry_from_Dominode: We'll be there w/ a booth. Drummond Reed: Drummond will be at Consensus - and a number of other folks from the Sovrin Foundation. Moses Ma: It's Cherie Duncan Lionel Wolberger: Impact of changes in impact of Facebook? More interest? [scribe assist by Manu Sporny] Nathan George: Also a note that many folks will be at the European Identity Conference that runs the same time as Consensus Lionel Wolberger: Comment on the Facebook personal data leak issues and its impact... Joe Andrieu: More a shift in Twitter debates (as opposed to FB) ... This was more an outside IIW, but it is getting clear that some things broken in FB can be fixed by DIDs Chris Webber: I'm here Andrew Hughes: Twitter is the focus of a debate about verifiable credentials Ed Eykholt: Nice article by Kailya Young https://www.coindesk.com/theres-alternative-facebook-called-self-sovereign-identity/ ... self sovereign identity is attracting interest in multiple threads Drummond Reed: Andrew is right - there is still a lot of confusion about self-sovereign identity and verifiable credentials. The Twitter threads are good evidence of that. Moses Ma: A couple of notable media companies have asked me to assemble a webinar/podcast about how DIDs might fix Facebook's problems. If anyone has ideas about this, I'd love to hear from you. Heather Vescent: Can someone link to the twitter thread? ... people in the user-centric movement are trying to reconcile latest developments ... looking at the similarities and new features e.g. cryptographic proofs, and the latter does show that there is some innovation and something new here Drummond Reed: The thread on Twitter is indeed engaging the user-centric folks (openID, UMA, SAML) ... surprising amount of push back and lack of understanding differentiating between that (openID, UMA, SAML) and DIDs ... solutions and working code will help ... FB issues: IIW did have some conversations. And Sovrin is experiencing more inbound interest, Kaliya's article helped. SSI = self-sovereign identity Chris Webber: I work on ActivityPub ... we see an uptick in people involved with the federated social networks ... alternatives are in place to catch people who are now looking ... current interfaces are more like Twitter, less like FB ... but these use a small portion of the technologies discussed here ... DIDs are not used (obviously) ... for those interested, look at Social Community Group Chris Webber: Could you send a link to some of your work on decentralized social networks? [scribe assist by Ed Eykholt] .... This FB incident is an extreme screwup, but this is not a unique event. FB/Twitter leaks will continue to drive interest in us Manu Sporny: https://www.w3.org/community/fedsocweb/ Chris Webber: https://www.w3.org/wiki/SocialCG Manu Sporny: Urges us to focus on what has to be done to serve the upcoming opportunities Drummond Reed: +1 To Chris' point that the migration from centralized social networks to decentralized social networks is going to take years, and that it will have many small milestones, not one huge leap. ... use cases, architectural review, privacy review... ... these are critical milestones and if we miss we will not make the TPAC requirements Andrew Hughes: Heathervescent, start here and follow down https://twitter.com/coindesk/status/982076954336808961 Andrew Hughes: Heathervescent, also here: https://twitter.com/bobblakley/status/983345568725553152 Joe Andrieu: Twitter engagement is bringing UMA, SAML advocates to look at the DID/VC work and dialog with this group ... Issue: conflation of SSI ideology (political movement reclaiming human authority) with SSI mechanisms (systems, technological manifestations/implementations) ... Focusing on untangling these two issues can help move forward the conversation ... as there are $$$$Billions already invested in IT that will need to work with these new systems Joe Andrieu: Proposed, upload twitter threads as stories Lionel Wolberger: <Clapping for first story experiment!> Joe Andrieu: Sovrin method spec, propose to review on a call ... next week ZKLang focus Moses Ma: Bye people Kim Hamilton Duffy: Bye! Joe Andrieu: Cheers all
