Description

This PR enhances the consensus algorithm in the following ways:

  • Reduces the ChangeProposerTimeout to 5 seconds and increases ChangeProposerDelta to 5 seconds. This allows the proposer change to start one second earlier and the next proposer change to start one second later.
  • Moves the basic check for proposals to the consensus phase. This optimization benefits nodes that are not part of the committee.
  • Adds the round to the query proposal message. This ensures that messages with expired rounds are ignored.
  • When a validator sees a proper and justified "Decided" vote, it moves the consensus to the vote's round, even if it is a prior round.
  • The proposer responds to the query-proposal message. This helps to reduce the number of consensus messages.
