Network distribution refers to the fact that the network in question is geographically distributed, with multiple nodes across various locations and countries, which would entail a distribution over the internet, or through a Virtual Private Network (VPN) to support the network in a confidential manner. This is the classical approach and structure of network distribution. Modex BCDB further expands on the concept of distributed network by enabling clients to create multiple subnetworks and distribute them across the globe.

Subnetworks play a vital role in the architecture of the node network. Data sharing specifications are configured per node in accordance with limitations and restrictions of the region/country where the node network physically resides. As a result database synchronization within the respective subnetwork can be restricted according to use case, or legislation. Similarly, each subnetwork is composed of full and partial nodes, but synchronization with other networks can be restricted depending on the limits imposed by the law.

In essence, subnetworks can be perceived as an enclave within the blockchain network. A use case that perfectly illustrates the potential of the subnetwork organization structure can be found in the finance industry, where data migration is strictly regulated. Keep in mind that the presence of multiple subnetworks does not mean that there are multiple blockchains. It forwards the idea that access can be restricted according to the region or even country to ensure that data manipulation falls in line with the rules and regulations that pertain to that territory. Although everybody uses the same blockchain, the information stored within it is minimized, mostly composed of metadata, which maintains a certain degree of pseudonymity. In a distributed network, access control mechanisms ensure that data can be accessed only with the consent of the database owner.
