Smart contracts, blockchains (distributed ledgers), and rights management broadly construed are the themes of today's Spotlight Patents. Assigned to ANT, the first patent addresses techniques for detecting replay attacks. Assigned to Vijay Madisetti, the second patent addresses techniques for service meshes and smart contracts for zero-trust systems.

A computer-implemented method for detecting replay attack comprises: obtaining at least one candidate transaction for adding to a blockchain, the obtained candidate transaction comprising a timestamp; verifying if the timestamp is within a validation range and if an identification of the candidate transaction exists in an identification database; and in response to determining that the timestamp is within the validation range and the identification does not exist in the identification database, determining that the candidate transaction is not associated with a replay attack.

A blockchain-enabled network and application service mesh network architecture including a network service mesh network including network service domains configured to communicate with each other, each including network service endpoints and a network service manager to broadcast the availability of the network service endpoints. The architecture further includes an application service mesh network that includes applications configured to communicate with each other and a network service domain. Smart contracts including network slicing information from the network service mesh network and the application service mesh network are recorded to a blockchain network.
