2.3.2 Network Access Control Taxonomy

return to Taxonomic Views

Network access control taxonomy classifies the types of access individuals (i.e., nodes) have from outside and from within the node network. The two main classes of access control are permissionless and permissioned.1)

Within each of these two classifications it is possible to have public and private access. Public and private access define who is able to write data onto a network or ledger. In contrast, open (i.e., permissionless) and closed (i.e., permissioned) determine who is able to read the data. Networks are classified as2):

  • public and open
  • public and closed
  • private and open
  • private and closed

Another category of networks is a hybrid network, which makes it possible to restrict the visibility of information on the network using a combination of public, private, permissionless and permissioned networks. Therefore, hybrid networks are appealing to regulated markets because they offer the benefits of public blockchain and private blockchain together.3)
