According to an embodiment of a first aspect of the invention, there is provided a distributed network comprising a plurality of subnets. Each of the plurality of subnets comprises a plurality of nodes. The network is configured to run a set of computational units and to assign each of the computational units to one of the plurality of subnets according to a subnet-assignment, thereby creating an assigned subset of the set of computational units for each of the subnets. The network is further configured to run on each node of the plurality of subnets the assigned subset of the computational units and to replicate the assigned subsets of the computational units across the respective subnets. The network is further configured to exchange unit-to-unit messages between the computational units via a messaging protocol based on the subnet-assignment. Further aspects of the invention relate to a corresponding computer-implemented method, a node, a computer program product and a software architecture.

Messaging in distributed networks

According to an embodiment of a first aspect of the invention, there is a distributed network comprising a plurality of network nodes. Each of the plurality of network nodes is linked to a first node identity of a plurality of first node identities. Each of the plurality of first node identities comprises a first verification key of a public-key signature scheme. The distributed network is configured to perform a key shuffling step adapted to perform an unlinkable one-to-one mapping between the plurality of first node identities and a plurality of second node identities. Each of the plurality of second node identities comprises a second verification key of a public-key signature scheme. The distributed network is configured to perform a consensus protocol with a subset of the plurality of second node identities. Further aspects of the invention relate to a corresponding computer-implemented method, a network node and a computer program product.
