In this task we investigate how to optimize the propagation of transaction information, i.e., transactions in the Mempool.
This task takes as input the results of #9922 and previous discussion, such as #9050

Tasks

• Investigate solutions used by other protocols
  • Narwhal
  • Solana
  • Celestia
  • Other approaches

DoD:

• We identified alternatives to how to propagate transactions 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.
