Function gossip_best_tip_block_hashes

pub async fn gossip_best_tip_block_hashes<ZN>(
    sync_status: SyncStatus,
    chain_state: ChainTipChange,
    broadcast_network: ZN,

Run continuously, gossiping newly verified block::Hashes to peers.

Once the state has reached the chain tip, broadcast the block::Hashes of newly verified blocks to all ready peers.

Blocks are only gossiped if they are:

• on the best chain, and
• the most recent block verified since the last gossip.

In particular, if a lot of blocks are committed at the same time, gossips will be disabled or skipped until the state reaches the latest tip.
