General

  • Sprint and next release
    • 2-week sprint started Jan. 7. Priority is platform stability, bug fixes, and feature specification.
    • RNode v0.8.2 released on Jan. 7. At a high level this release delivers bug fixes and optimizations contributing to bugs related to platform stability, expanded test coverage for Casper, and a new implementation of the metrics API to benefit debugging, reporting, and RNode operators. Please see RNode-0.8.2 release plan for more details.
  • Mercury requirements and acceptance criteria
    • Ongoing effort to ensure completeness of feature-based user stories in the Mercury features doc (https://github.com/rchain/rchain/blob/dev/docs/features.md). We have tooling in place to show the status of the definition of the feature (Can we describe a test scenario to demo the feature?) and the status of the feature's completeness if the test is implemented. Demo of tool.
  • Work with Whiteblock
  • Test net status
    • A public test net is not yet available. 
    • A view of the issues blocking launch of a public test net is available here.
    • Platform stability is priority #1 for most people on the team.

Rholang

  • PR for the block store is in and is in review. Integration tests passing.  Work continues to improve checkpoint behavior for the blockstore. RCHAIN-652 - Getting issue details... STATUS

Casper 

  • Discussing Validator Incentives and Casper and implementation of cost accounting to support Mercury requirement work.
  • Implementation of RhoSpec complete. This is a class that collects failures from Rholang tests and reports them as scalatest failures. Next step is to complete work so we can use this with TestResultCollector in Casper tests.
  • Bug investigation that looked like an issue with validator bonding, and now appears to related either to the code or the algorithm. We have a unit test to recreate the issue and investigation is underway. Plan is to try a fix to the code: changing the assertion so that all blocks are the same instead of ensuring there is only one  block in the list.   RCHAIN-2805 - Getting issue details... STATUS

Node 

  • Completing work for stream API on client queue with retries. Last PR in review.  RCHAIN-1904 - Getting issue details... STATUS
  • PR in review to stop receiving stream blobs if they don't fit in memory.  RCHAIN-1615 - Getting issue details... STATUS
  • Updates to DAG grapher to group blocks by validator. This tool has been very helpful in debugging.
  • Profiling of RNode in progress.  RCHAIN-2765 - Getting issue details... STATUS

SRE team 

  • Priority is stability work and testing.
    • v2 of RDoctor used in this week's community test.
    • Improving delivery of data from the Rundeck testnet
    • Supporting Whiteblock team
    • Optimizations to integration test coverage
