Network parameters are a set of values that every node participating in the zone needs to agree on and use to correctly interoperate with each other.

Parameters:

minimumPlatformVersion - Minimum version of Corda platform that is required for nodes in the network.

notaries - List of well known and trusted notary identities with information on validation type.

maxMessageSize - Maximum allowed size in bytes of an individual message sent over the wire.

maxTransactionSize - Maximum permitted transaction size in bytes.

modifiedTime - (annotationclass AutoAcceptable) Last modification time of network parameters set.

epoch - (annotationclass AutoAcceptable) Version number of the network parameters. Starting from 1, this will always increment on each new setof parameters.

whitelistedContractImplementations - (annotationclass AutoAcceptable) List of whitelisted jars containing contract code for each contract class.This will be used by class WhitelistedByZoneAttachmentConstraint.You can learn more about contract constraints here.

eventHorizon - Time after which nodes will be removed from the network map if they have not been seenduring this period

packageOwnership - (annotationclass AutoAcceptable) List of the network-wide java packages that were successfully claimed by their owners.Any CorDapp JAR that offers contracts and states in any of these packages must be signed by the owner.
