2021 Sprint 11 2021.06.01 - 2021.06.14

Retrospective pad: https://pad.riseup.net/p/7MJ__a8coM6N7GwcUZoH

Sprint 11 will be a shorter (1 week) sprint due to Zcon2 happening during the second half of the sprint

During this sprint we will:

• Implement Block Header Chain History Commitment which will involve:
  • Updating the Zebra state implementation for the finalized tip, and
  • Updating the Zebra state implementation for non-finalized chains
    This will allow us to finish ZIP-221 implementation and is a prerequisite for
  • finishing ZIP-244 implementation by adding the transaction authorization hash to the block header commitment field.
• Finish off the last of the transaction v5 testing
• Continue working on Zebra security fixes to mitigate distributed denial of service risk by:
  • limiting the reconnection rate to each individual peer address in Zebra, and
  • limiting the number of active peers maintained by Zebra.
