Abstract: This disclosure describes aspects of an efficient blockchain API communication mechanism that reduces the energy usage and data usage. In some examples, a publish-subscribe mechanism is used for completed transaction receipts for blockchain transactions of a blockchain. The publish-subscribe mechanism uses an open source remote procedure call protocol or hypertext transfer protocol (HTTP). Components of a distributed blockchain application use a single transport or communications protocol for both synchronous and asynchronous communications.

Abstract: An I/P converter is disclosed. The I/P converter comprises a nozzle (7) coupled to a magnetic circuit. A temperature compensation ring (3) is coupled to the top side of the magnetic circuit. A flexure (1) is coupled to the temperature compensation ring. The temperature compensation ring is configured to position the flexure relative to a first end of the nozzle and the temperature compensation ring is configured to maintain the relative position between the nozzle and the flexure over a range of temperatures.
