157:. Although the content of the transactions themselves is not subjected to consensus because it is handled by the hashgraph itself, their ordering and timestamp still needs to be. A modified version of Proof of Stake is used for this purpose, characterized by not submitting votes as messages in the protocol but rather by "virtual voting", i.e. applying a voting algorithm to calculate what other witnesses of an event would have to vote based on their copies of the hashgraph, and weighting the votes according to the stake of the voter. This is argued to increase efficiency by reducing message-passing.

Baird responded that "All of the nodes at a given time know how many nodes there are." A hashgraph developer at the time noted that "...a node joining the network is a transaction like any other - it gets assigned a consensus timestamp, after which point all nodes now include it in consensus."
