In this task we investigate how to optimize the propagation of proposals, i.e., proposal messages and block part messages.
This task takes as input the results of #9922 and previous discussion, such as #7932.

Tasks

• Investigate solutions used by other protocols
  • Solana
  • Coded Hotstuff
  • Other alternatives
    • Would a pull-push work better than the current push only?

DoD:

• We identified alternatives to how to propagate proposals that may be applied to Tendermint and have an initial comparison of pros and cons of each alternative. This data serves as input to an ADR to address the problem.
