Enum ConsensusOutMessage 

pub enum ConsensusOutMessage {
    Vote(Vote),
    Proposal {
        block: Block,
        proposer: Address,
        round: u64,
        view: u64,
        high_qc_view: u64,
        timeout_certificate: Option<TimeoutCertificate>,
        no_endorsement_certificate: Option<NoEndorsementCertificate>,
    },
    Timeout(TimeoutMsg),
    NoEndorsement(NoEndorsementMsg),
}

Messages the consensus engine needs to broadcast via gossipsub. Uses an mpsc channel to avoid a circular crate dependency: tenzro-consensus cannot import tenzro-network.

Variants

Vote(Vote)

A vote this node cast that peers must receive to form quorum

Proposal

A block proposal the leader is broadcasting to all validators. timeout_certificate is Some(_) only when the leader is recovering from a view timeout — it carries 2f+1 timeout signatures from the previous view so peers can verify the new view was legitimately abandoned (Jolteon vote rule, DiemBFT v4 §3.5).

no_endorsement_certificate is Some(_) when the leader is proposing a new block at view N+1 after view N timed out — it carries f+1 no-endorsement signatures from view N proving the predecessor’s QC was not withheld. MonadBFT (arXiv:2502.20692) — closes the tail-fork MEV vulnerability. If absent, receivers must require the proposal to repropose the high-tip block; a fresh block with neither a NEC nor a high-tip parent is rejected.

high_qc_view is the leader’s local highest-Prepare-QC view at the moment of proposing (#171, Aptos SyncInfo pattern). Receivers use it to fast-forward their own high_qc_view if the proposer is ahead, which shrinks the gap a lagging replica has to close before it can vote. Must satisfy high_qc_view < view.

Fields

block: Block

proposer: Address

round: u64

view: u64

high_qc_view: u64

timeout_certificate: Option<TimeoutCertificate>

no_endorsement_certificate: Option<NoEndorsementCertificate>

Timeout(TimeoutMsg)

A pacemaker timeout broadcast emitted on local view-timer expiry. Carries the sender’s current view so a lagging peer can fast-forward (DiemBFT v4 §3.5 backward-sync channel; phase 1 of #164).

NoEndorsement(NoEndorsementMsg)

A no-endorsement attestation broadcast emitted on local view-timer expiry. Aggregates into an f+1 NoEndorsementCertificate that the next leader attaches to its proposal when proposing a new block (MonadBFT, arXiv:2502.20692).
