In the case of public networks or networks for ecosystems, a hybrid H-Net structure is proposed. Its main features include: * The network combines several segments of different access types. This includes several private segments controlled by consortium participants, as well as a public segment. * The joining of nodes to private segments is controlled through a certificate mechanism adapted for decentralized use. * Nodes interact with the network through gateways and cluster intersections are not allowed. Each node belongs to one and only one segment. * Nodes have different roles. In addition to the typical validators, leaders, and arbitrators, such roles as Notary are added – which interacts with off-chain operations, as well as Gateway – which interacts with other networks.
