Iurii requested the order of transactions, I am currently clarifying the use case. The current approach may not work. Will resolve the issue and provide suggestions to RFC.
Also reviewing the state to be in sync.
There is a question regarding the transaction forwarding: currently peers broadcasts transactions to the leader only. We can broadcast transactions for everybody, to avoid malicious leader related issues.
Makoto Takemiya > If the block is finalized and the leader does not want to add it to the chain, we need to find a way how to avoid it.
I got the idea, will describe it in the RFC for the Sumeragi.
