Greg Meredith提供了基于渠道的安全性和自我主权身份方面的知识分享。 Ned Robinson代替Kelly Foster进行技术更新会汇报。开发团队专注于稳定性和代码修复。目前正在招聘另外五名开发商,以帮助加快主网交付。董事会提交利益冲突披露。在会议结束前Greg详细阐述了Casper共识协议作为回应Pyrofex对构建即纠错的批评。
 
Greg Meredith回应了Pyrofex在Twitter上对Casper CBC的批评。 根据他的说法,Pyrofex的批评是一个误导,并且是对第一次RChain开发者务虚会所解决的问题的回顾。该批评的观点是对Casper共识协议使用分而治之方法(安全和liveness)这一事实的诋毁
•他还解释了RChain网络如何防止分叉。这是因为可以将分叉作为额外的名称空间或分片进行安装
•Greg Meredith阐述了使用Rholang语义(Rick和Morty情境)对抗Pyrofex的Casper规范(与同步约束假设相关)。

Timeline  
Content in Brief
 
Greg Meredith’s brain candy: channel-based security and self-sovereign identity
  • Greg Meredith gives a presentation on the notions of identity in which he addresses:
    • Communication acts across a range of channels
    • Channels can be things like phone numbers, email addresses, blockchain addresses
    • Expectations about those communication acts
    • Claims as communications made about basic observations including communications about communication acts and claims about claims
  •  
  • He also showed how these communication acts can be expressed in Rholang
Technical update:RNode v0.8.1 released, stability work and bug fixes
 
General
 
RNode v0.8.1 released
  •  
    • See node-0.8 release plan for information about this release and links to artifacts and a docker image. We will update the website as soon as web development support is available to assist
Test net status
  •  
    • A public test net is not yet available. We do have a development test net running to support debugging work
    • New debugging tool created this week to help visualize the blockchain. This tool produces a text file that can be pasted into Graphviz to create an image like the one shown below. Planned additions include information in the blocks for the name of the validator
    • Platform stability is priority #1Mercury requirements and acceptance criteria
    • The work continues to collect and define user stories defining the requirements for Mercury
    • The development team has worked this sprint to support the creation of test cases and acceptance criteria for stories that are ready
    • User story requirements, testing scenarios, and status will be reported in features.md. This is a work in progress. When complete, stakeholders will have a web-based dashboard showing the requirements and the status of the acceptance criteria
  •  
Work with Whiteblock
  • In progress. Waiting for handoff from Whiteblock to the development team so they can begin using this testing resource.
Rholang team
  • In addition to supporting stability work, working on other bugs and continuing work on the block store
Casper team
  • Fully focused on stability work
  • Working to build in-depth Casper knowledge on the team. Kent led a learning session with members of the team late last week. This increased the ability of others on the team to support Casper-related work
Node team
  • Priority is work related to platform stability. This includes work with the SRE team to improve metrics and monitoring to assist with platform debugging
  • Bug found in Kademlia (CORE-1546). Introduced by a change a few weeks ago that did not create failures in CI. Work in progress to both resolve the bug and expand the test coverage for Kademlia and the P2P protocols
Storage team
  • Priority is stability work
  • Review of the peek prototype is in progress
SRE team
  • Made significant improvements to the CI process last week by implementing Bors support for the timing of CI relative to the opening, review, approval, and request to merge PRs. This already reduced testing time, caught some issues early, and better assures PRs don’t break dev
  • Support work for the release of RNode v0.8.1 this week
  • Other work supports the stability effort
Developer website
  • Awaiting web development support to make updates related to the release of RNode v0.8.1 and to the REV issuance page, which no longer reflects the current timeline for the Mercury release
  • Derek, Ian, and Kayvan have been working on updating the web property. Derek hopes to get full access to the website within a few days

  • Individuals who received payment from the co-op (specifically for Americans) should fill out their 1099 form for tax preparations
  • The board has submitted its conflict of interest disclosures
  • Draft for membership governance participation waiting for review from the governance committee to make progress with it
  • Volunteers interested to be enlisted in the governance committee should indicate their interest in the governance channel on Discord
  • Unofficial board minutes have been published on GitHub
