Abstract: Various embodiments of the present disclosure relate to a leaf spring for coupling a heat sink to an integrated circuit, where the leaf spring includes a central portion that has an aperture, a first spring arm that is formed on a first side of the central portion and includes a first through-hole for a first fastener, and a second spring arm that is formed on a second side of the central portion and includes a second through-hole for a second fastener. In various embodiments, a first bending axis passes through the first side and is substantially perpendicular to a longitudinal axis of the leaf spring that passes through the first through-hole and the second through-hole, and a second bending axis passes through the second side and is substantially perpendicular to the longitudinal axis of the leaf spring.

Abstract: The present disclosure provides an architecture of a cloud computing oriented high-performance blockchain including a cloud computing oriented blockchain network architecture and a cloud computing oriented blockchain system architecture; wherein the cloud computing oriented blockchain network architecture enables each blockchain node to be directly connected to an RDMA, and to bypass an operating system kernel and directly communicate with a network card in a high efficiency communication mode; and the cloud computing oriented blockchain system architecture includes a network layer, a consensus layer, and a blockchain layer. According to the present disclosure, network communication is implemented by the RDMA, and a block broadcasting speed is improved, and a block synchronization latency is shortened.
