Attending: Adam, Thomas, Kathleen, JohnW, Adrian, JeffS
Adrian's use cases are reasonable, and not new. Thomas: Identity is a problem that predates blockchains technologies. So BSC-DG will not address this as a new issue. Identity is an issue separate from blockchains.
Thomas: do the MedRec issues get solved using bchains. For consent captured, yes. Kathleen: but bchains does not solve the policy issues, notably in the contesxt of EHR record access and sharing. There is also the added issue of PII-leakagaeleakgae. (Kathleen may write it up - critique of medrec and solutions). Thomas askes asks about how people do EHR in Europe. Kathleen will ask the Europewns at next HL7/Security WG.
JohnW: bchains can also be used by abusers (e.g. Bob presuares pressures Alice to sign conswent) to record. Thomas: agree bchains don't solve socio-cultural (people) problems.
Looking at list of uses cases, Thomas suggested we rename the "Stellar" use case into a better title ("Data Sharing Agreements"). JohnW will contribute 1/2 page (maybe copying from his coming whitepaper).
JohnW: The ability to write the next block in the chain is a "right" to be earned. Bitcoin uses PoW. Stellar uses a separate consensus algorithm. No single answer. Depends on scenario. Aspects include leader-selection, etc. Notion of "leader" means the node who finishes/wins PoW and gets the right to write to bchains.
