Agenda: - Report <http://kantarainitiative.org/confluence/display/BSC/Report+from+the+Blockchain+and+Smart+Contracts+Discussion+Group> 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-308497> 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-best-practices-for-distributed-systems>. 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!*
