6. Community update

The holidays are already upon us, and our December community contest is right around the corner. The contest will start on December 1st and will continue through the end of the year. Apollonauts will have the opportunity to compete each day for a chance to win free APL.

If you are interested in helping on our community team, volunteer opportunities are always available. Please contact our community director Lee Behnke for more information.

7. Development team update

The team has finished:

  • A bug fix for secret file import/export (desktop)
  • Fix to restore functionality for the alias send feature
  • Implementation of a new endpoint to return a contract by order ID
  • Addition of a new page where users can view a list of errors
  • Fix to restore the ability to search by account ID

The team is continuing work on:

  • TradingView chart implementation
  • Data modeling for TradingView chart (backend)
  • Updating mobile wallet applications
  • Bug fixes

The team has deployed these fixes on testnet and regression tests are underway. Over the next few weeks, the team will focus on fixing bugs discovered by QA specialists during these test cycles and preparing the code to move to the next stage of tests in preparation for the next public release.

Sharding and code optimization

Regression testing continues as the team focuses on fixing various bugs discovered during these cycles, for example:

  • Number format exception
  • Shard creation is skipped
  • Issues with shard import and phasing pool
  • Problems with prunable parts of the shard archive

The testing process is further complicated by the need to restart the sharding process after each fix is applied.

Additionally, the team is continuing optimization of resource consumption on hardware nodes. Some users have reported problems such as:

  • Slow block generation (more than 12 seconds for some transactions)
  • Nodes with limited memory availability falling out of sync

Progress on this issue has been made and the team is preparing an update of the H2 DB version (to v.1.4.200). This update should allow for data migration without a full blockchain download.

The team is continuing to develop integration auto-tests.

DAG R&D

The team is continuing the development of a viable mathematical model for DAG, the best defensive countermeasures for possible attacks and solutions to the following problems:

  • The time complexity of topological sorting
  • Solutions to the longest path problem
  • Determining if a path between two vertices exists in a directed graph
  • DAG processing logic
  • Defining key guarantees and achieving Liveness

8. Academic review and validation
