public class Party extends AbstractParty implements Destination
The class Party class represents an entity on the network, which is typically identified by a legal name and public key
that it can sign transactions under. As parties may use multiple keys for signing and, for example, have offline backup
keys, the "public key" of a party can be represented by a composite construct – a class CompositeKey, which combines multiple
cryptographic public key primitives into a tree structure.
For example: Alice has two key pairs (pub1/priv1 and pub2/priv2), and wants to be able to sign transactions with either of them.
Her advertised class Party then has a legal X.500 name "CN=Alice Corp,O=Alice Corp,L=London,C=GB" and an owningKey
"pub1 or pub2".
class Party is also used for service identities. E.g. Alice may also be running an interest rate oracle on her Corda node,
which requires a separate signing key (and an identifying name). Services can also be distributed – run by a coordinated
cluster of Corda nodes. A class Party representing a distributed service will use a composite key containing all
individual cluster nodes' public keys. Each of the nodes in the cluster will advertise the same group class Party.
Note that equality is based solely on the owning key.
Communication with other parties is done using the flow framework with the FlowLogic.initiateFlow method. Message routing is done by
using the network map to look up the connectivity details pertaining to the class Party.
