Abstract: An example operation may include one or more of generating an initial seed and allocating one or more authorized bits of the initial seed to a plurality of blocks in a distributed ledger, storing the initial seed and an identification of which authorized bits of the initial seed are allocated to each block of the distributed ledger, receiving a final seed value that is partially generated by each of a plurality of nodes configured to access the distributed ledger based on authorized bits of respective blocks updated by each respective node, and generating a random sequence value based on the final seed value and storing the random sequence value in a block of the distributed ledger.

Abstract: Provided are systems, methods, and media for verifying a commission-based relationship in a communication system. An example method includes generating authorization information by an authorizer that is to be transmitted to a caller and forwarded by the caller to a callee upon a call being initiated between the caller and the callee, in which the authorization information includes at least authorizer identity information, callee identity information, and a caller public key. The method includes signing the authorization information with a private key of the authorizer and transmitting the signed authorization information to the caller. The caller is configured to generate a digital signature via a private key of the caller and transmit the digital signature and the signed authorization information to the callee. The callee is configured to verify the identity of authorizer, caller and callee and event information based on the authorization information.

Abstract: A heat dissipating device for a heat generating unit, includes a heat sink placed on the heat generating unit, and two clip members located at opposite sides of the heat sink for securing the heat sink to the heat generating unit. Each clip member includes an operating member movably attached to the heat sink, and a fastening member connected with the operating member. The operating member is movable from a lower position to an upper position to cause the bottom portion of the fastening member to move upwardly via the operating member acting on the fastening member.
