High level summary​

  • Updated UTXO-HD to use simple diffs which drastically improved the mempool benchmarks (#1114).
  • Helped quickcheck-state-machine to release version 0.10.0 (#48). We rely on this library for our high-assurance property-tests.
  • Rebased UTXO-HD on top of node 8.11 (#1121). A replay with the in-memory backend took 5:05 hours up to slot 124M.

  • Presented, reviewed and merged the March milestone for Genesis.
  • Integrated latest changes into Node version 8.10.
  • Regarding the UTXO-HD feature we:
    • Completed fixes in test-suites from cardano-node, cardano-api, and ouroboros-consensus. All tests are passing in latest prototype.
    • Prepared UTXO-HD prototype for LMDB benchmarking.
    • Fixed tracing in cardano-node.
    • Started merging code from the UTXO-HD branch into main (1053, 1052, and 1054).
  • We're currently working on getting rid of NoThunks errors in Consensus, so that we can enable these tests in CI, for extra assurance.
