[08:17] == wayne_ [~wayne@public.cloak] has joined #blockchain
[08:20] <marta> marta summarizes what happened in lisbon based on the meeting report
[08:21] <marta> use cases https://github.com/w3c/blockchain/wiki/Use-Cases
[08:21] <marta> victoria: are we still seeking for more use cases?
[08:22] <marta> ...yes
[08:22] <marta> victoria: how do we deal with tradeoffs between use cases?
[08:23] <marta> ??: there is no way to avoid the tradeoffs, we should categorize and prioritize.
[08:24] <marta> victoria: as long as we are explicit that we identify tradeoff and this is a standard for this particular use case
[08:25] <wayne_> Marta, that was me making those comments about tradeoff ;)
[08:25] <marta> victoria: we need to be clear as to what type of blockchain standard we are using
[08:26] <marta> mountie: it is a complex question, what is blockchain
[08:26] <marta> mountie: maybe we need to narrow down the scope to certain chains only
[08:27] <marta> victoria: we need a generic definition of blockchains, to be able to communicate with people
[08:28] <mountie> maybe we mute mic than the speaker
[08:28] <marta> it seems that people are interested what a blockchain is rather how can it be applied to
[08:29] <marta> victoria: i have been working on definition i can shae
[08:30] <david> I also have a definition that I have been working on
[08:30] <david> it's a one liner
[08:30] <marta> blockchains are at war, they compete. Its a challenge to create something everyone will accept
[08:30] * shepazu notes that the Verifiable Claims WG has not actually been formed, only proposed
[08:31] <marta> we can come up with a great standard but if miners do not agree with it then they won't use it
[08:31] <david> an immutable distributed permissioned transparent ledger with scalable storage, computing and workflow capabilities that enables permission real-time interactions, configurable consensus and replaces implicit trust with cryptographic proofs.
[08:31] <marta> david: its also a great opportunity as well
[08:32] <mountie> q+
[08:32] <marta> ack mountie
[08:34] <marta> wayne_: davids definition works well for bitcoin world but doesn't encapsulate everything and yet its packed.
[08:35] <marta> wayne_: we may be forever tied up here if we try define the blockchain
[08:35] <marta> david: i do agree with you
[08:36] <marta> wayne_: we should pick the ones where we have the most impact on
[08:36] * shepazu hard to hear over the background noise from david
[08:36] <david> I've gone muted
[08:37] <david> Rodolphe was asking
[08:37] <marta> rodolphe: start with use cases or definitions
[08:38] <mountie> https://github.com/w3c/blockchain/wiki/What-is-Blockchain
[08:38] <mountie> shortly created wiki page to gather comments from members
[08:38] * shepazu hard to hear marta
[08:39] <marta> marta: we will get into a rabbit hole if we start with that definition
[08:39] <wayne_> ^ x 1000%
[08:40] <marta> we should start with use cases, see which ones make most sense to us and define what blockchain is to us
[08:42] <marta> victoria: state tracking, distributed consensus mechanism, crypto hashing, repackage transactions into blocks and distribute, (controversial) digital currency usage in some way to determine the validity.
[08:42] <marta> victoria: these are the properties for me
[08:43] <shepazu> +1 to characteristics vs definition
[08:43] <marta> wayne_: list of characteristics is a better idea in my opinion than a definition
[08:43] <marta> +1 from me as well
[08:44] <marta> is it uncommon to discuss non-web stuff?
[08:44] <marta> mountie - we will discuss mostly web related stuff
[08:46] * shepazu can barely hear marta
[08:46] <marta> shepazu would you post your prioritization criteria?
[08:47] <shepazu> priorities / categories
[08:47] <shepazu> * key stakeholder interest
[08:47] <shepazu> ** implementers (and to a lesser extent, deployers)
[08:47] <shepazu> ** competitor agreements, not clients
[08:47] <shepazu> * active participants
[08:47] <shepazu> * readiness of tech
[08:47] <shepazu> ** maturity of spec
[08:47] <shepazu> ** willing deployers
[08:47] <shepazu> * breadth of use cases
[08:47] <shepazu> * relationship to browsers / client-side Web
[08:53] <marta> I think its a great list and will be a good start
[08:53] <marta> will share it on the mailing list
[08:54] <marta> Beecoin - full bitcoin node running in a browser
[08:54] <wayne_> bcoin.io
[08:55] <marta> marta to invite them to participate
[08:55] <wayne_> Here's a link to Bcoin's announcement.  I think they might have a lot to contribute to this group. https://medium.com/purse-essays/introducing-bcoin-fdfcb22dfa34#.ronl79vah
[08:56] <marta> till next meeting everyone to express their opinion on existing usecases
[08:57] <marta> mountie: korean blockchain cg mailing list is up and there is interest
