  disclosure.
  ... ZKLang
Manu Sporny: Any relationship to KD Lang? :P
Kim Hamilton Duffy:  Has a lot of verifiable credentials examples 
  throughout
  ... Good opportunity for questions.
Mike Lodder:  Working with Jann. High level view of ZKLang, give 
  developers a simpler language for implementing ZK proofs
  ... math heavy, but actually is a simpler implementation
  ... wraps different methods into a common language to be used

Topic: Action Items

Manu Sporny:  DID method spec, almost published... Many pull

  add session topics to the Helsinki conference.
  ... Markus has a session setup devoted to these topics.
Ed Eykholt: I'm interested in this.  ed.eykholt@pithia.com
Drummond Reed: I strongly encourage CCG members to attend if you 
  can and submit CCG talks for MyData2018.

Topic: Work items - DID Spec and DID Methods

Lionel Wolberger:  Lots of Chairs to do things in Action Items... 
  is that being progressed. DID Use Cases, DID Charter, etc. 
  [scribe assist by Manu Sporny]

  week
Joe Andrieu:  "Chairs" actions remain on the list. Some will be 
  reported on in the IIW report-out
Kim Hamilton Duffy:  Occupational VCs. Reviewed paper around 
  alignment of VCs and Open Badges
  ... options how to structure the Verfiable Credentials envelope

  ... add to work items, Kim did a pull request on the methods 
  spec.
Manu Sporny: +1 For initial skeleton version, update w/ dates.
Manu Sporny:  DID working group charter being worked on.
  ... Some discussion on a DID Working Group at W3C. May announce 
  in W3C Plenary.
  ... if it is to happen, lots of work to complete and key 
  milestones/events to meet on the way
  ... But people, NOTE-- the interest in DID that is generating 
  'rumors' or thoughts of other groups doing a DID working group
Kim Hamilton Duffy: Thanks @manu; will do
  ... NOTE that this could harm the process of getting the WG 
  going at W3C.
  ... Let's allow the W3C process to complete, we need this to 
  happen at the right time, and based on the right deployments of 
  the spec and so on
Mike Lodder:  COmpleted Sovrin DID method spec, published in the 
  Sovrin foundations git repo
Manu Sporny: 
  https://github.com/w3c-ccg/did-method-registry/pulls/

Topic: IIW26 Report Out

Drummond Reed: Just FYI, just for the record, I have an action 
  item to complete my issues and PRs on the DID spec.
Joe Andrieu:  Work item -- drum up W3C Member company support for 
  DID WG.
  ... 3 companies were very receptive and supportive. Good start.
  ... Window of six months to onboard them.
Manu Sporny:  Breakout session @ IIW.
  ... Triggered by a piece by Samantha. She expressed, 'my 
  background is not STEM but I want to participate'
  ... Session to humanize DIDs and engage philo, humanities, UX 
  people
Manu Sporny: https://w3c-ccg.github.io/stories/
  ... Heather is interested, Jeff attended this call ;could 
  inolove Samantha, Denise
  ... outcome: a focus on stories.
Moses Ma: "Humanizing DIDs" is brilliant
Manu Sporny:  Stories that explain what we are trying to achieve 
  here.
  ... explainers, stories, fables, sagas-- open a wide tent 
  including the format (word, git, PDF)
  ... Next step Heather, Jeff, Manu strategize on how to engage 
  these people and reap what they produce

ACTION: Chairs to add CCG Stories to work items.

Joe Andrieu:  Add to work items: Add stories.
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.
  ... DKMS demo was shown, the same that was done at DHS
  ... largest session was explaining ZK proofs using only 
  Japanese high school math
Dan Greening: 
  https://www.ultrasaurus.com/2018/04/zero-knowledge-proof-trust-without-shared-secrets/
Dan Greening: ^^ Is a transcription
Manu Sporny:  Veres One did a number of sessions at IIW. 
Manu Sporny: We did a Verifiable Credentials and DIDs Primer: 
  https://drive.google.com/open?id=1GMQy4rI093c_9zojwLRgp2r-fTscpDUSfX-wqwBk4j4
Manu Sporny: We did a DID Methods Lightning Talk series: 
  http://iiw.idcommons.net/DID_Ledger_Lightening_Talks
Manu Sporny: We did a Veres One Demo session: 
  https://drive.google.com/open?id=1H3Uej16DilTDOL8BKqKQKdhhrdPkk6BoJTectlfwGko
Manu Sporny: We did a Veres One Deep Dive: 
  https://drive.google.com/open?id=1bUZbtgdxKxTR1it10G9ZozYGD486qxZTBPuiOZjzoT4
Drummond Reed: The link to the DKMS Design and Architecture 
  document that was released by Evernym to the Hyperledger Indy 
  repository is 
  https://github.com/hyperledger/indy-sdk/blob/master/doc/dkms/DKMS%20Design%20and%20Architecture%20V3.md
  ... primer on DIDs and VCs. Well attended.
  ... Lightning Talk style presentations on DID methods as they 
  are being implemented. Nathn on Sovrin. UPort presented. IPFS. 
  Veres.One
  ... deep dives followed. Evernym/Sovrin did one. Veres.One did 
  a deep dive on governance and performance.
Manu Sporny: They had 250+ people at this IIW
Manu Sporny: Normally, they have around 180
Joe Andrieu:  IIW was very well attended.
  ... 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
