General

• Release
  • Node version 0.9.15 is the current release RNode-0.9.15 release plan
  • Testnet is currenty running rnode version 0.9.15

  • The 0.9.15 includes the new type safe API (instead of Either), some fixes for Long Proposal Times Issue, Offchain-data API (events API) improvements and other incremental progress in features discussed below.

• Sprint 40 in progress
  
  • Main focus is on reaching Testnet 3 (a) Cost accounting  (b) Long proposal times - Fairness Constraint and other improvements (d) Additional tests for multisig features (e) ongoing work in Casper tests independent of network layer (f) Ongoing work in Planning and implementation for Network safety, reliability and hardening
  • Cost accounting
    • Design and Scope of work at https://gist.github.com/ArturGajowy/73e481767548b084a8e5d7c19bb1f70c
    • Implementation in progress for these preliminary tasks needed for implementing the main portions of cost accounting:
      • Merged - Some refactorings needed for Cost Accounting are completed and currently being reviewed e.g.  https://github.com/rchain/rchain/pull/2770
      • Generalize NormalizerEnv -PR reviewed and changes made. Expecting to be merged tomorrow.
      • Merged - Validate user deploy cost in replay  https://github.com/rchain/rchain/pull/2767/commits
      • In review - Bulletproof unforgeable-name namespace uniqueness by prohibiting terms wider than Short.MAX_VALUE splits/terms https://github.com/rchain/rchain/pull/2768
      • Merged - Remove DeployData.payment log, included in https://github.com/rchain/rchain/pull/2767
      • Merged - Signed[A: Serialize] with a signing smart-constructor
      • Created PR to secure access to protocol-private PoS methods
      • Merged - Casper refactorings needed for Cost Accounting mainly to improve type inference - https://github.com/rchain/rchain/pull/2761
    • The 'System Deploy' construct,

       necessary for cost accounting, is implemented and in review. Expected to be merged soon.
    • In parallel, work has started on combinatorial Rholang terms in contracts, to test stability of cost accounting across such combinations.
    • Remaining chunks of work in cost accounting are (a) writing the charging logic

  • Reduce long proposal times: 
    • Initial implementation of a (simple round robin) fairness constraint as an additional mechanism to address long proposal times.  PR https://github.com/rchain/rchain/pull/2776  corresponding to

       is in review, and waiting to be merged. Final tests are currently being done to measure actual improvement from this fairness constraint.
    • Observed that 'create block' is where the rabbiting behavior starts. Investigating reasons thereof to understand the problem at a more granular level.

      • In review -Persist last finalized block https://github.com/rchain/rchain/pull/2780 
      • In review - Add new termination condition for isInMainchainhttps://github.com/rchain/rchain/pull/2775
      • Disallow invalid blocks as parents

    • We continue to explore various test parameters and more complex contracts, to both test the stability of this issue and make it manifest sooner if it exists.
  • Rspace
    • In Progress - In RSpace, an API is implemented for DAG discovery and block discovery, to enable an alternative to ListenForData@Name (Off-chain observability of deploy results). Relevant tickets are
