Node discovery
Tessera uses peer discovery to discover Tessera nodes in the network. Tessera nodes share their entire peer list, enabling new nodes to discover all nodes in the network. When sharing their peer list, Tessera broadcasts the public keys for that node and the list of URLS with which the node has current active communication.
Tessera maintains two node lists, PartyStore and NetworkStore. NetworkStore lists nodes with
which an active connection has been established. PartyStore lists URLs from the peer entry in the Tessera configuration file
and URLs discovered from remote nodes. If Tessera can no communicate with a node, the peer is
removed from both the PartyStore and NetworkStore lists.
If all peers are removed from the PartyStore and NetworkStore lists, the PartyStore list is repopulated
from the peer entry in the Tessera configuration file.
A dropped remote peer is added to the NetworkStore list only after establishing direct communication with
the peer. That is, discovering a dropped remote peer is not enough for a node to be added to the active peer list.
The partyinfo API method returns nodes
with which Tessera has a current active connection (that is, nodes listed in NetworkStore).
