Notes from BSC telecon Thursday, September 22

http://kantarainitiative.org/confluence/display/BSC/2016-09+%28September+20… Agenda: - Report <http://kantarainitiative.org/confluence/display/BSC/Report+from+the+Blockch…> writing - Search for independent and dependent variables among the "tensions", as inspired by Kathleen and John W for the report - Review use case analysis inputs from John W for the report, if available Attending: Eve, Matisse, Thomas, Colin, Andrew, Marco *News: *News has hit of an "editable" blockchain technology <http://www.econotimes.com/Accenture-creates-Editable-blockchain-prototype-3…> that Accenture has prototyped. This seems...kind of scammy. They seem to have created a private blockchain. Does it require proof of work? Is it really a blockchain? Why would you want to "accelerate...adoption" of blockchain by removing a key defining feature of actual blockchains? Maybe this makes enterprises feel cool, but tamper-evident ledgers can be done right now without having to involve the "b-word". We pronounce this another b-word: bogus. *Tension/theme analysis: *Can a blockchain be considered "a distributed system" in the formal sense? There are a number of resources we could draw on to analyze its characteristics if so: scalability, transparency, etc. See this article <http://www.theserverside.com/feature/Bitcoins-blockchain-architecture-as-a-…>. Matisse supports this analysis, as it's the premise of her PhD. thesis! A neutral way of stating the columns Kathleen has added on the right that our participants are more invested in, for use-case reasons, would be (all, please offer feedback on this): - "Balance of control" in transactions (which can include contracts and data sharing) – enabling individuals to rise to the level of a "peer" to traditionally more empowered entities - "Transactions" is the broadest possible term in common usage - This item is the broad descriptor - "Granularity of control" ?? in transactions – enabling not a totality of trust and liability but an apportioning that is appropriate - Supposedly Bitcoin, a special-purpose blockchain, has protected individuals on this dimension, but each smart contract could still leave individuals open to abuse - "Dynamism of control" ?? in transactions – enabling individual choice both over time and just-in-time When is a public blockchain appropriate, vs. a consortium-model blockchain, vs. a private blockchain? *AI:* Matisse: Share pointers to papers to let us analyze specific blockchain types for next time. Next time: Get into both specific blockchain mentions and use case-specific analysis, and try to flesh out the report intro for good and all. *Eve Maler*ForgeRock Office of the CTO | VP Innovation & Emerging Technology Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl *ForgeRock Summits and UnSummits* are coming to <http://summits.forgerock.com/> *London and Paris!*

http://kantarainitiative.org/confluence/display/BSC/2016-09+%28September+20… Agenda: - Report <http://kantarainitiative.org/confluence/display/BSC/Report+from+the+Blockch…> writing - Identify strengths and weaknesses of traditional and new distributed methods of solving use cases Attending: Eve, Scott S, Jeff, Matisse, Andrew, Jim H, Domenico, John W Eve reviewed a graph that Kathleen essayed in private email, with three axes: economic paradigm, (political) governance model, and (openness) community type. (s/oligarchy/oligopoly/) We're enthusiastic about finding out how technologies would get plotted. We wonder if there are exactly three axes and if they're really orthogonal. Can we start by taking the matrix approach in Kathleen's first email, and "checking off" (as in John W's Stellar matrix example) characteristics/features that each technology has? Since there are so many consensus protocols and they change fast, we want to take a relatively high-level approach for a key sampling of these. For the Alice Participates in Bob's Research Study <http://kantarainitiative.org/confluence/display/BSC/Alice+participates+in+B…> use case, what are the strengths and weaknesses of doing things using today's technologies and techniques? - Registries related to particular diseases, such as cancer – clinicaltrials.gov – centralized control systems record the outcome of studies but don't engage with the patient in any way. - To add such functionality, you'd have to bolt something on, or develop a linking mechanism in between the two. How could things be different? - An information sharing agreement (a la JSON-LD) would point to the study (which has a study number) and to the data needed (or a pointer to it). - Consent? - Retrofit? - Efficiency? - Accountability? - Trust mechanism? How do you establish that the next slot in the chain is trustable? To what extent does this involve the "drug of centralization" once again? - Automatability/dynamism? - If solved with "just blockchain", has these S&W - If solved with "smart contracts", has these S&W - If solved with both... - If solved with IPFS... A pattern we're imagining in the report is that many use cases will have similar strength and weakness patterns, and we'll want to discuss those in one big analysis section. Each use case may then have its own small subsection(s) discussing delta as necessary. For example, if we think that "automation vs. manual" is a strength of new tech vs. old tech, and "privacy" is a weakness of new tech vs. old tech, we can say that once in the big analysis section. We might end up* recommending a Work Group that develops an architecture, or set/range of architectures, that targets optimal outcomes among the strengths, and mitigates the risks among the weaknesses.* The ISO now has a blockchain group. Next time: - Search for independent and dependent variables among the "tensions", as inspired by Kathleen and John W for the report - Review use case analysis inputs from John W for the report, if available *Eve Maler*ForgeRock Office of the CTO | VP Innovation & Emerging Technology Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl *ForgeRock Summits and UnSummits* are coming to <http://summits.forgerock.com/> *London and Paris!*

User-Managed Identities for Blockchains (using UMA for user-centric control over blockchain identities)
by Thomas Hardjono 11 Sep '16

11 Sep '16

Folks, This may or may not be a use-case proper for BSC-DG, but I thought I'd mention it here because its an "infrastructure" technology that supports scaling of blockchains. (analogy: DNS is not part of Internet routing in TCP/IP, but it sure does help us use the Internet). One of the key concepts we (at MIT) are trying to develop further in CoreID (diagram is here http://www.findthomas.net/blog/) Part of it is the idea of a new kind of identity provider called the "persona provider" (PP) The Persona Provider could be implemented as a combination of an UMA Authorization Server combined with an UMA Resource Server. (PP = AS + RS). When Alice creates an account at the Persona Provider (PP), she convinces the PP initially that she is legit by supplying the PP with signed assertions (blinded assertion) which the Core Identity Issuer (upstream) has created. When Alice needs to transact on the blockchain using an anonymous-verifiable identity, she goes to her account at the PP and self-generates a transaction-identity (transaction-identifier) to be used on the blockchain or within a smart contract. She can self-generate as many transaction-identifiers as she needs -- no limit. The PP provides the crypto-tools to do this (just like bitcoin-wallets / client softwares or PGP). At the same time, she could optionally set policy on the account, treating the the blinded assertions (from the Core Identity Issuer) as resources. The transaction identities (which are anonymous-verifiable strings) can also be treated as resources sitting on the PP. The PP keeps these transaction-identifiers as long as she needs, and may even archive them. The PP also makes available a Identity Verification end-point (API) that allows the counter-party (RP) -- or anyone for that matter -- to verify a transaction-identifier found on a blockchain or in a smart-contract. If this is useful, I can write it up for the use-cases page. /thomas/
