Developing Applications

This section describes the tasks performed by CorDapp Corda Distributed Application. A Java (or any JVM targeting language) application built using the Corda build toolchain and CorDapp API to solve some problem that is best solved in a decentralized manner. Developers. For more information about the architecture of Corda 5 from the perspective of CorDapp Developers, see the Key Concepts section. Depending on the stage of development, Corda supports the following types of networks:

• Static
• Dynamic

Static Networks

Static networks are intended for local testing when the list of virtual nodes or members in the network are predetermined. These networks are composed of only a single cluster as there is no instance of the Membership Group Manager ( MGM Membership Group Manager. May also be referred to as the Network Manager. It is a virtual node and Corda identity that acts as a central registrar for group membership. ) to distribute member data across clusters.

Dynamic Networks

Dynamic networks are used for the following:

• Production networks
• Testing across multiple clusters
• Testing when the number of members are not predetermined in your test network

One of the main differences to static networks is that there is a running MGM that all members must register with before they can transact among the group. The MGM is also responsible for distributing member data across clusters.
