Onionr uses a flavor of Dandelion++ epidemic routing
|
|
|
|
The starter creates a peer set and passes it to the client and server
|
|
as well as each of the plugins.
|
|
|
|
The transports forward incoming requests to the gossip server
|
|
|
|
When a new peer announcement is recieved an event is fired and the transport
|
|
plugin that handles it will (or wont) create a new peer object by connecting
|
|
to that peer
|
|
|
|
When a new block is generated, it is added to a queue in raw form passed to
|
|
the starter
|
|
|
|
In stem phase, client uploads recieved (stem) blocks to 2 random peers.
|
|
In stem phase, server disables diffusion
