• Working out the test plan and SLA for HackerOne.

• Scope creep is paramount.  The team is concerned about locking down what we will deliver for Mercury.

Rholang team:

• Show-blocks issue - suspect that this may be related to context switching around threads.   Workaround is to use show-block with the block's hash 

• Work continues on the name registry.

• Team met to discuss the Casper block store, goals being to improve the story for validator recovery and performance improvements.

• Uplifting the integration tests by moving these to PyTest & making the tests modular.  Once complete, this work will be turned over to the SRE team.
