Algorand Specifications

The Hybrid Network is currently in experimental mode, as it includes Peer-to-Peer Network functionalities.

Let’s define NHNH as an object that models a working Hybrid Network HYBHYB.

The Hybrid Network NH=NWS∪NPNH=NWS∪NP is the network layer that unifies the Relay Network WSWS and the Peer-to-Peer Network P2PP2P.

Nodes in the NHNH act as gateways, running simultaneously WSWS and P2PP2P for the interoperability of both network layers.

Conceptually, all functions and implementations of HYBHYB act as a switch statement to select the appropriate network layer according to the parameters of the sender PeerPeer of the incoming message.

A Hybrid Network maintains both the Relay Network definition and the Peer-to-Peer Network definition.

See also the HYBHYB identity challenge for details on how peer deduplication works in both subnetworks.

The following sketch represents a typical topology of a Hybrid Network NHNH, where:

• RR represents a relay node,
• PP represents a peer node,
• HH represents a hybrid node,
• PrPr represents a peer node connected to RR,
• PpPp represents a peer node connected to PP,
• HH represents a hybrid node, connected both to RR and PP,
• A PrPr is connected on average to 4R4R,
• A PrPr is not connected to other PP,
• A PpPp is connected on average to 4P4P,
• A HH is connected on average to 4R4R,
• A HH is connected on average to 4P4P,
• A RR is connected to multiple RR.
