The collected evidence is inspected to determine whether at least two VMs in the one or more VMs share a same host machine in the one or more host machines. At least one VM is requested to be redeployed to meet a policy based on results of inspecting the collected evidence.

In some embodiments, SI messages into divided into SI groups, preamble/RACH resources are only reserved for each of the groups, and SI request windows are implemented. In an example, an SI request window precedes each set of SI windows corresponding to a group of SI messages, and an SI request is transmitted only in an SI request window. The disclosed implementation may increase the efficacy of supporting a greater number of users, which may be ubiquitous in 5G implementations.

Abstract: A method for electing a leader in a blockchain network using a role-based consensus protocol includes generating a new block by a node in the blockchain network and computing an effective resources metric for the node based on a role of the node, resources of the node and a role-based weight profile for the resources of the node. Eligibility proof of the node is generated based on eligibility information that includes a blockheader of the new block, an identity of the node, a difficulty target, T, of the blockchain network, and the effective resources metric. The new block and the eligibility proof is broadcast to the blockchain network, to enable one or more other nodes in the blockchain network to verify eligibility of the node as a leader.

Abstract: A method of providing secure ledger distribution for interbank settlement includes maintaining a first consensus layer in a mainchain among a plurality of nodes of the centralized computer system and a second consensus layer in a first private sidechain among at least one node of the centralized computer system and computer systems of at least a first sender bank and a first receiver bank, each of which have an account with the central bank.
