15:10:11 <manu> Topic: Overlap with Web Payments WG Meeting
15:10:29 <manu> mountie: I spoke with AdrianHB and MikeSmith about them sharing information wrt. local industry and blockchain
15:10:41 <manu> manu: Yes, we overlap with the Web Payments WG call
15:10:48 <manu> Topic: Agenda
15:11:03 <manu> marta: Let's start, thanks to Manu for joining the call today.
15:11:12 <mountie> https://digitalbazaar.github.io/flex-ledger/
15:11:34 <manu> mountie: Let's focus on Flex Ledger first, then hope to talk about CG's activity
15:11:49 <manu> mountie: Want to get to Flex Ledger first.
15:11:57 <manu> Topic: Flex Ledger
15:12:08 <manu> https://w3c.github.io/flex-ledger/
15:12:20 <weiler> scribe: weiler
15:12:46 <weiler> manu: this is highly experimental work; we're not saying this is the right way to do it.  this is just a conversation-starter.
15:14:04 <weiler> ... Digital Bazaar asked by DHS (homeland security) to review existing blockchains.  map out capabilities of each blockchain w.r.t security and privacy.
15:14:40 <weiler> ... paper submitted to Rebooting Web of Trust.
15:15:52 <weiler> ... looks at bitcoin, etherium, ipfs, blockstack, stellar.  re: selective disclosure, anonymous identifiers, time to reach consensus.
15:16:33 <weiler> ... then propose standard protocol and format to access of all above. e.g. add ledger entry, get history
15:16:50 <weiler> ... trying to create unified data model and protocol for different blockchains.
15:17:24 <weiler> ... not trying to restrict blockchains to this model, but trying to spec a unified client based on observed commonalities.
15:17:41 <weiler> ... does this make sense to you?
15:18:42 <weiler> marta: concerned that you'll ruffle feathers.
15:19:11 <weiler> manu: we've already gotten that.  "no reason to have unified interface"
15:19:54 <weiler> ... talked to bigchaindb and sovereign ledger; they're open to discussing it.  but you're right, there has been pushback.
15:20:11 <weiler> ... communities feel like theirs in the best and they see no need to intro.
15:20:17 <weiler> s/intro/interop/
15:20:29 <weiler> s/in the best/is the best/
15:21:39 <weiler> manu: ... some want to be able to switch ledgers in the future.  if they see features they want to add, etc.
15:22:46 <weiler> mountie: @@ JSON.ld
15:23:08 <weiler> manu: json should be supported, but looking at other things e.g. yams.
15:23:13 <weiler> s/yams/yaml/
15:24:24 <weiler> ... can we unify protocol and translate data in blockchain into unified format?
15:26:02 <weiler> mountie: is the possible to handle ...  w/ flexledger web could be gateway of transitions...
15:27:14 <weiler> manu: we hope to see a standardized protocol to access blockchains.
15:30:09 <weiler> zakim, who's here?
15:30:09 <Zakim> Present: Marta, Mountie, Manu, weiler, thessy, Haiyang
15:30:11 <Zakim> On IRC I see marta, mountie, RRSAgent, Zakim, weiler, newton, rrware, manu, bovesan, rhiaro, fluffypony, kat, nicolagreco, robmyers, hadleybeeman
15:31:47 <weiler> mountie: how to do model achieving consensus?
15:32:34 <weiler> manu: consensus mechanism is just a field; we don't otherwise model it.
15:34:05 <manu> https://w3c.github.io/flex-ledger/#http-api
15:37:05 <weiler> (much digging into the details missed by the scribe)
15:41:07 <weiler> manu: have the CG discussed the prospect of having thousands of ledgers?
15:41:54 <weiler> marta: yes
15:42:10 <weiler> manu: worth pursuing?
15:42:58 <weiler> marta: yes, because @2.  not sure we'll be able to come w/ solution unless industry wants to collaborate with us.
15:43:58 <weiler> manu: dead in the water unless other players sign on.  hoping sovereign foundation and @3 and get their thoughts on this.  if we can get three blockchains implementing to something, even if not flexledger, we might get some traction
15:44:20 <weiler> ... maybe the right approach is not to convince big players, but convince startups.
15:44:25 <weiler> ... to show some traction
15:45:28 <weiler> mountie: web can be gateway for thousands of bc's. this is the right time to start.
15:47:35 <weiler> manu: at tpac, the people w/ web experience didn't really understand BC and were just there to learn.
15:47:51 <weiler> ... need both bits of clue to create an API.
15:48:55 <manu> http://dhs2016ledger.digitalbazaar.com/
15:49:01 <weiler> manu: I hope that showing W3C a spec in a form they're familiar with, that will draw in more people from w3c.  but making it concrete v. abstract.

15:49:36 <weiler> manu: feel free to play with implementation at link above.
15:50:45 <manu> scribe: manu
15:51:05 <manu> mountie: I found that there is great possibility to use Flex Ledger and study it.
15:53:27 <manu> marta: What do you need from the CG?
15:53:53 <manu> manu: 1. Do you want to adopt the Flex Ledger spec as a spec under incubation at the CG?
15:53:57 <marta> +1
15:54:05 <mountie> +1
15:54:07 <manu> manu: +1 :)
15:54:32 <manu> manu: Do you want us to pull companies in to discuss Flex Ledger in the CG? Like Sovrin and BigChainDB?
15:55:32 <manu> marta: We discussed this on the call, wanted to make a decision on Flex Ledger - we already discussed before, but wanted you to come in and introduce it to us a bit.
15:56:26 <manu> mountie: I have some questions on Sovrin, but for BigChainDB - I think I have latest info on that.
15:56:56 <mountie> https://www.sovrin.org/ ?
15:57:01 <marta> I said that unless people vote within next 30 sec we should decide based on the existing votes
15:58:58 <manu> manu: Sovrin is a decentralized ledger that is tuned for identity.
15:59:15 <manu> mountie: Do we need to vote for the 2nd ask?
16:00:06 <marta> how many votes did we get
16:00:37 <marta> great lest then just go with a yes for both?
16:01:21 <manu> mountie: no objection to invite BigChainDB and Sovrin to Blockchain CG.
16:01:31 <manu> manu: Rodophe was there from BigChainDB at W3C TPAC.
16:02:08 <manu> mountie: That's the call for today, will try to get some activity started at Blockchain CG... been busy.
16:02:17 <manu> marta: We'll discuss that during the next meeting.
16:02:39 <marta> 2 weeks
16:02:42 <manu> Topic: Next Meeting
16:02:54 <manu> mountie: When should we have the next meeting?
16:03:13 <marta> No, lets just have it in 2 weeks
16:03:19 <manu> manu: I wont be able to make most of these meetings because of the conflict w/ Web Payments WG :(
16:03:31 <marta> We will reschedule them as well
16:03:39 <manu> mountie: Let's take this to email
16:03:44 <manu> rrsagent, draft minutes
16:03:44 <RRSAgent> I have made the request to generate http://www.w3.org/2016/12/01-blockchain-minutes.html manu
16:03:49 <marta> I'll send out a doodle
16:04:16 <manu> weiler: The CG web page has the old WebEx link, can we put up the current concall link?
16:04:30 <manu> mountie: Yes, I will update it
16:04:35 <manu> rrsagent, draft minutes
16:04:35 <RRSAgent> I have made the request to generate http://www.w3.org/2016/12/01-blockchain-minutes.html manu
16:05:08 <marta> but could you email them as well
16:05:14 <marta> please
16:11:30 <manu> marta, did you mean "email the minutes"?
16:12:30 <marta> yes:)
16:12:41 <marta> thank you
16:12:41 <manu> marta, I'll do that :)
