Re: [Hyperledger Project TSC] Minutes 02.11.16

Perhaps Jesus means, will the ledger system include any information that could potentially be used to identify a person? (e.g. an e-mail address or social security number or company registration number). This is different to using some kind of UUID (for example) to represent the transacting entity, which makes it very difficult/expensive to trace a real-world person.

The UUIDs are and should, of course, be openly and publicly visible, but personal/company information should not. Otherwise this opens companies and individuals up to all sorts of attacks. If there’s no privacy, it’s akin to opening up your personal/business bank account (or transaction log/etc.) for the world to see. Nobody wants that for themselves.

Privacy should be one of the top priorities.

I don't think we have to consider privacy in an open ledger system. In an open ledger system all information is open. By definition. So there is no private information. If somebody wants to keep information private, he is not supposed to put the information into the system the first place.

Hi all.

Thanks for the email, it is very useful for all of us who could not attend the complete meeting (or attend at all).

One doubt/comment about the evaluation criteria. Is privacy being considered as part of the security criteria (or any other criteria, although I'd say that it fits better in security, if any) or not at all?

If not being considered either explicitly nor implicitly, I'll give it a thought. A system may be really secure (in terms of confidentiality (!= privacy), integrity, availability and so on) against any kind of considered attacker, but still lack privacy.

In the concrete context of blockchain, as in most other contexts, a proposal may be privacy-respectful depending on the use case For instance, private "enough" for conventional value transactions, but not private enough for managing information storage.

Best,

Jesus

Welcome to the (now official) Hyperledger Community. Thank you to everyone who helped with the launch of the project and getting everything lined up for a very strong start.

We have a technical community call scheduled for Thursday at 10am Eastern Time. The GoToMeeting details are below. Our apologies for last week’s disruption with the 25 person limit. We have fixed that issue and now have a 100 person capacity. I’m also copying both the TSC and the technical-discuss mailing lists. In the future, we will just use the TSC mailing list for TSC meetings. However, I didn’t want to miss anyone this first week, so I’ve copied both lists. If you have not signed up for any mailing lists, you will want to do so here: https://lists.hyperledger.org/mailman/listinfo

I look forward to our discussion tomorrow.

— Mike

Proposed Agenda

I’ll propose the agenda below for tomorrow, if you have other thoughts / comments, please let me know.
  1. Process for electing a TSC Chair (10 mins). Also, if you are a Premier member and have not yet notified Todd (CC’d) of your TSC Chair representative, please do so ASAP. We will distribute a list of the TSC reps to the TSC when we have everyone identified.
  2. Discussion of tools/services that would be helpful to the community. We have setup IRC:  #hyperledger on freenode with Meetbot. We have the mailing lists. Does the TSC want to see anything else? E.g. Slack? A wiki such as https://wiki.linuxfoundation.org/hyperledger shared wiki or setup wiki.hyperledger.org?
  3. Future meeting day/times? Do we use this time slot for the TSC going forward or does the TSC prefer a different cadence and/or time or day?
  4. Discuss where/how to land code. Common question we’re getting is “where is the code?” Need to discuss how to get proposed code into public review.
  5. Discuss process for getting to a code starting point. Proposal template for evaluation? 
  6. Discuss proposals for the common starting points 
    • Networking
    • BFT
    • Storage
    • Cryptographic libraries
    • Member services
1. Proposed TSC Chair Election Process
  • Begin nomination period: Thursday, Feb 11th, nominations includes a short bio/pitch less than 1 page
