The present invention is notably directed to methods, systems and computer program products for securing data operations in a computerized system comprising interconnected nodes, wherein the nodes are configured to transmit, receive and store data, and wherein the method comprises executing computerized cryptographic methods to implement two or more proofs of work that comprises: provably crawling, from each node of at least a subset of the interconnected nodes, a respective subset of data stored on nodes of the system; and provably acquiring, at each node of the subset, data in the subset of data.

Cryptographic methods implementing proofs of work in systems of interconnected nodes

Electronic circuit device and method for conveying clock signal in an electronic circuit device. The electronic circuit device includes: a cooling fluid conduit network including at least one conduit, wherein the cooling fluid conduit network is configured to convey both a cooling fluid and an electromagnetic signal via the at least one conduit; a clock signal injection unit configured to inject an electromagnetic clock signal at an input location of the cooling fluid conduit network; and a clock signal collection unit configured to collect an electromagnetic clock signal.

Electronic circuit device with electromagnetic clock signal conveyed along cooling fluid conduit network

An electronic circuit device, including a combined optical transmission and cooling fluid conduit network. The network includes at least one cooling conduit having an optical transmission medium. The network is configured to convey a cooling fluid via the at least one cooling conduit and to convey an electromagnetic signal via the optical transmission medium. The network is in thermal communication with a first set of one or more components of the electronic circuit device and in signal communication with a second set of one or more components of the electronic circuit device. The first set and second set of components are at least partly overlapping. A method for conveying optical signal in such an electronic circuit device is also provided.

Fluid-cooled electronic circuit device with cooling fluid conduits having optical transmission medium

Electronic circuit device (ECD) and method for conveying clock signal in an ECD. The ECD includes: a cooling fluid conduit network (CFCN) including at least one conduit adapted for conveying an electromagnetic signal, wherein the CFCN is arranged in thermal communication with a first set of one or more components of the ECD and is in signal communication with a second set, and wherein the CFCN is configured to convey both a cooling fluid in the at least one conduit and an electromagnetic signal via the at least one conduit; a clock signal injection unit configured to inject an electromagnetic clock signal (ECS) at an input location of the CFCN; and a clock signal collection unit configured to collect at an output location of the CFCN, an ECS for one or more components of the second set, wherein the ECS is conveyed via a conduit of the CFCN.
