The Data Layer is comprised of eleven core modules:
1.
Identity: A unique peer identification, generally assigned to a single Member or device.
2.
Node: A peer in the network that establishes Transports, stream multiplexing and content routing.
3.
Message: A canonical format and signature structure for storing system state and constructing a zChain.
4.
zChain: A chain of signed Messages that is secured by a Merkle tree.
5.
Account & Avatar: A representation of account information, with the enabling capacity to combine Identities and multiple devices under a parent zChain.
6.
Network: A public or private namespace that is shared by Accounts or Identities.
7.
Clusters: A Cluster that represents two or more linked Networks.
8.
Peer Routing and Discovery: A shared format to ensure consistent addressing and data routing between Nodes within the Zero Grid.
9.
Gossip: A peer-to-peer protocol used to share messages between Nodes within the Zero Grid.
10.
zApp: A collection of one or more custom Message format and associated validation logic that enables the development and interoperability of custom Zero applications.
11.
Dyno: A peer-to-peer service (e.g. DAEMON) that peers can run and provide to the Zero Grid.
