Figure 3.1: Hedera Hashgraph’s Gossip Protocol

Gossip about gossip: Information is transmitted from node to node

through a gossip network. When a node receives the transactions, it

transfers or gossips this information to the next node which is called

an “Event”. While doing so, it also shares the identifiers of the

previous event as it received and also the previous event it sent. In

Figure 3.2, we can find a sample on what an event looks like, i.e.,

signature, timestamp, current transaction, and two hashes of the

other two transactions.

Virtual voting: As each participating node receives the events from

the others, they can independently analyse that shared history in

order to determine a consensus timestamp for all the transactions.

This consensus mechanism that Hedera’s participants use is called

virtual voting.
