  • Publication number: 20220377133
    Abstract: According to an embodiment of a first aspect of the invention, there is provided a distributed network comprising a plurality of nodes. Each of the plurality of nodes is configured to run one or more computational units comprising its own unit state. The network is configured to individually execute, by an execution subset of the plurality of nodes, s set of execution messages in a deterministic manner, thereby mutating the unit states of one or more of the computational units of the execution subset. The network is further configured to regularly make, by the nodes of the execution subset, a read snapshot of the unit states of the one or more computational units of the execution subset and to provide, by one or more nodes of the execution subset, user access to the read snapshot. Further aspects of the invention relate to a corresponding computer-implemented method, a node, a computer program product and a software architecture.
