Abstract: An apparatus, being a network entity of a computer network is provided. The apparatus comprises a communication module to receive and to send information on a blockchain. Moreover, the apparatus comprises a query module to obtain from a master chain of the blockchain a rule for a first shard and a second shard of the blockchain with respect to a smart contract. Furthermore, the query module is to obtain information on the smart contract from the first shard or from the second shard depending on the rule. Moreover, the query module is to output the information on the smart contract.

Abstract: A system and method for authentication are described herein. An authentication request is received at a combiner proxy (350). The combiner proxy (350), is arranged to receive a user authentication request, receive one or more share values from one or more communications devices (330A, . . . , 330N) where each of the communications devices (330A, . . . 330N) stores at least one share value of a set of share values and determine if one or more share values that have been received from the communications devices (330A, . . . , 330N) meet a quantitative criteria. The combiner proxy (350) is arranged to authenticate the user if the received share values meet the quantitative criteria.
