09 Feb '17

Hi folks-- Thomas is under the weather and I'm traveling tomorrow, so Devon has agreed to be our chair pro tem. We'll be using our normal Skype dial-in, but for the screenshare, we'll be using a *join.me <http://join.me> one-time code instead of findthomas*, so please join the call in order to find out the exact screenshare link (join.me/nnnnnnnnn or go to join.me in your browser and then enter the code). I've cc'd Kantara staff to ask them to please change tomorrow's calendar entry <http://kantarainitiative.org/confluence/display/BSC/Calendar>, if they're able to do so in time, to ensure people have the right info available at their fingertips. Thanks! *Eve Maler*ForgeRock Office of the CTO | VP Innovation & Emerging Technology Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl

blockchain for identity
by j stollman 01 Feb '17

01 Feb '17

I am seeking some insight from this group on the viability of blockchain for identity. The notion of a user-controlled, distributed identity mechanism strikes me as the holy grail in identity. But, like the holy grail, I am finding it difficult to believe that it is real. In particular, I don't see what the blockchain can add to identity. Yes, I recognize that blockchain does offer distributed consensus. And I while I am not persuaded that proof-of-work and/or proof-of-stake are as bulletproof as most people accept, I am not focused on these concerns. My concerns stem from what value add the blockchain provides to the inscrutable problem of identity. We can use blockchain to confirm that a particular transaction too place at a particular point in time. For example, we can use it to confirm that Alice paid Bob the $1000 he owed her within the terms of their agreement. This verification may be valuable in a subsequent credit transaction. And we can use blockchain to confirm that someone claiming to be Alice passed a background check by Bob at a fixed point in time where the background check attests to aspects of her health, home address, financial stability, national loyalty, trustworthiness with confidential data, or some combination of these. But even this information is only useful to someone who believes that Bob is trustworthy and thorough in his checking. And since Bob can never be absolutely certain that the Alice who sat in front of his desk is the Alice she claims to be, Bob's assessment -- no matter how trustworthy and thorough he is -- is always subject to some doubt. And how are we certain that it was really Bob who is asserting the claim on behalf of Alice and not an impostor Bob? Do we believe that merely possessing his private key is sufficient proof to an organized attempt to create a false Alice? I don't see anything about the blockchain that addresses these concerns which are - and always have been - at the root of identity and trust. So many people seem excited because blockchain offers a distributed governance model that uses economic incentives to encourage good behavior of vetting parties (e.g., miners). But tracking a single crypto-currency is a much more simple task that vetting identifies and the vast array of attributes of interest to relying parties - depending on their business. And unlike measuring crypto currency transactions which either do or do not take place, identify attributes are not 0/1 transactions. They are a collection of probabilities. And using blockchain does not change this. If I have a bad credit rating using one self-managed identity, why don't I just create a new identity and seek credit for it? As a newbie, I might not have a high rating, but it would likely be better than a bad rating. What am I missing here? Thank you.

Provenance definitions for BSC Report
by Kathleen Connor 31 Jan '17

31 Jan '17

Hi Below are the best Provenance definitions that seem appropriate for the BSC Report that I can find among the ISO/NIST etc. sources I reviewed. Provenance = DF: Information about entities, activities, and people involved in producing a piece of data or thing, which can be used to form assessments about its quality, reliability or trustworthiness. W3C PROV-Overview http://www.w3.org/TR/2012/WD-prov-overview-20121211 Provenance of a resource is a record that describes entities and processes involved in producing and delivering or otherwise influencing that resource. Provenance provides a critical foundation for assessing authenticity, enabling trust, and allowing reproducibility. Provenance assertions are a form of contextual metadata and can themselves become important records with their own provenance.

Verifiable Claims and standardizing around distributed ledgers to reduce the need for federations
by Adrian Gropper 24 Jan '17

24 Jan '17

All, You might find the outlines below useful to explain where this might be headed. I have no idea whether linked data is needed to get there but I do share their interest in deprecating the role of federations as a way to reduce the asymmetry of the current Internet as relates to individuals, including licensed professionals. To be more explicit about how I hope Verifiable Claims and distributed ledgers will help, right now licensed professionals tend to link their claims to an employer and the employer verifies the attribute, often injecting other strategic interests into the process. This reduces the autonomy of the licensed professional to a much larger extent than was the case with paper-based systems. Since licensed professionals don't buy IT directly, they have not seen the strategic reduction in their autonomy until rather recently as the actual impact of massive institutional record systems on the professional-individual relationship has begun to chafe. Adrian ---------- Forwarded message ---------- From: Luis-Daniel Ibáñez <L.D.Ibanez(a)soton.ac.uk> Date: Tue, Jan 24, 2017 at 8:58 AM Subject: [CfP] 2nd International Workshop on Linked Data and Distributed Ledgers To: public-blockchain(a)w3.org The 2nd International Workshop on Linked Data and Distributed Ledgers. https://sites.google.com/site/lddleswc2017/ <https://sites.google.com/site/lddlworkshop2017/> A workshop of ESWC 2017, Portoroz, Slovenia, May 29th, 2017 (1st edition will be held in conjunction with WWW 2017 - Perth, Australia) *Important Dates:* - *Submission deadline:* Friday March 10, 2017 - *Notifications:* Friday March 31, 2017 - *Camera-ready version:* Thursday April 13, 2017 Distributed Ledgers (DLs) have emerged as a novel way to manage and exchange different types of digital assets among a large number of agents operating in a decentralised way. Existing DL platforms are driven by use cases from different user communities. Each community has its own requirements regarding the level of decentralisation, privacy, and identity management that the ledger would need to offer. To allow for these developments to be applicable to a wider, and more complex range of applications, they will need to be able to interoperate, both with existing distributed systems and databases technologies, and among each other. This has motivated researchers and practitioners to look at approaches such as Linked Data, which relies on core Web principles and standards such as URIs, HTTP, JSON-LD, RDF, and SPARQL. We envision the workshop as a forum for researchers and practitioners from Distributed Ledgers and Linked Data to come together to discuss common challenges; propose solutions to shortcomings of existing architectures; and identify synergies for joint initiatives. The ultimate goal is the creation of a Web of Interoperable Ledgers. The first edition of LD-DL will be held as part of WWW 2017 in Perth, Australia We invite original research submissions addressing any of the following two broad themes: Linked Data for Distributed Ledgers: Vision, insight and research on how to use Linked Data and Web technologies to enhance Distributed Ledgers, including but not limited to: • Architectures and protocols for DL interoperability • Architectures and protocols for interoperability between DLs and other Web components and architectures (non-ledger based web services, web databases, etc) • Extensions of web data models and formats to accommodate Distributed Ledgers (JSON, HTTP, HTML, RDF, etc) • Languages and query engines for Distributed Ledgers • Privacy considerations of interoperating Distributed Ledgers • Vocabularies and ontologies for describing DLs and Smart Contracts • Semantification and linking of DL frameworks and their contents • Storage, querying and updating RDF data inside Distributed Ledgers • SPARQL extensions to use it as a Smart Contract language. Extensions to current Smart Contract languages to use semantic data. Distributed Ledgers for Linked Data: Vision, insight and research on how to use DLs to enhance Linked Data and Web applications, including, but not limited to: • Decentralisation and disintermediation of web-based architectures. • Distributed management of identity and online identity. • Distributed Ledger backing of general Linked Data processes: vocabulary and dataset evolution, entity naming and re-naming, etc. • DLs for Web and Linked Data provenance. • DL-backing of Web signatures • Digital rights management and enforcing -- Dr. Luis-Daniel Ibáñez Research Fellow Web and Internet Science Group University of Southampton -- Adrian Gropper MD PROTECT YOUR FUTURE - RESTORE Health Privacy!

http://kantarainitiative.org/confluence/display/BSC/2017-01+%28January+2017… Agenda: - Report <https://docs.google.com/document/d/1HOVJ3lKqOIjwCqPt5jFxfLr7wEoJ0ZVNbMGsdsW…> work Attending: Eve, Matisse, Susan, Devon, Marco, Kathleen, Adrian, Thomas Kathleen notes that HL7 has woken up to blockchain, and says it will be doing something by 2018. Adrian will be speaking <https://cyber.harvard.edu/events/digitalhealth/2017/01/Gropper> at Harvard Law School on Thursday on "free, independent health records"; the talk will include a lot about UMA. PPR will be filling comment on the Sedona work. *Verifiable claims:* We looked at Manu's responses to Adrian's questions. Adrian is advocating for moving away from federation. Thomas and Eve's analysis focused on being dubious about much being new in the approach vs. what's possible with JWTs, and this being troublesome from the perspective of "respecting and balancing all ecosystem parties' needs". Kathleen comments that for our readers to consider the spectrum of ecosystems (tight to loose), what is the most an individual should "have to put with" just to get the service they want and have trust? The goal should be to find discoverable semantics, and compute the trust you need. One thing we missed in the W3C charter is that it talks about extensible semantics. But otherwise it doesn't differentiate what it's trying to do from other claim formats. The temptation is to design a JWT-based format that has the extensions that do what VC is doing! Susan observes that it was ID2020 that was the impetus. She suggests going back to the VC people and asking for a brief analysis that shows a compare/contrast over existing tools in extended form, for the empowerment goals we hold (the charter doesn't mention this goal). Lowering friction in development and deployment is one that we're concerned about (for accelerating adoption and also for reducing complexity = greater security); can they speak to that? Thomas notes that people are starting to change out the word "trust" for the word "blockchain". Yikes! But then it still gets down to key management; the problem hasn't gone away. This could turn into an Observation. *AI:* Eve: Ask Manu if it's okay to share his responses with the group, and let him know that we're discussing our whole analysis. *Eve Maler*ForgeRock Office of the CTO | VP Innovation & Emerging Technology Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl

We discussed the CommonAccord section in the report. John created a diagram (file name "BSC DG Decision-Making Power 2017-01-19.png" on Eve's computer) to describe the opportunity to even things up. Eve suggests creating an Observations section talking about contractual mechanisms and tensions around them, with the diagram as a centerpiece; it would pull in a lot of mentions of the tech/techs. Some Recommendations that may fall out could do with strengthening the connection between legal and smart contracts in a formal way. We discussed the Legal Contracts section. We debated the order of tech/tech sections; it would be nice to have Smart Contracts and Legal Contracts very near each other. The notion of "fully executed legal contracts" brings them together conceptually. *Next Tuesday:* Look at Manu's answers on Verifiable Claims, and look at Eve's putative new sections, and look at the User-Submitted Terms section from JohnW. (*NOTE:* Eve can't make next *Thursday's* call because she'll be doing a Data Privacy Day event in SF <https://www.eventbrite.com/e/live-from-twitter-hq-data-privacy-day-event-20…>, and hopes Thomas can run it.) *Eve Maler*ForgeRock Office of the CTO | VP Innovation & Emerging Technology Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl
