Abstract: Some embodiments can include method for decentralized data storage and validation. In many embodiments, the method can comprise receiving provided data at one or more decentralized storage modules for storage, wherein at least one of the one or more decentralized storage modules resides on a masternode, validating the provided data against a defined schema, and obtaining a decentralized multi-party consensus indicating acceptance of the provided data. In a number of embodiments, the method further can comprise writing a hash of the provided data for storage in a blockchain module, synchronizing the provided data across the one or more decentralized storage modules based at least in part on the hash stored in the blockchain module, and retrieving the provided data from the at least one of the one or more decentralized storage modules. Other embodiments of related methods and systems are also provided.

Abstract: A connecting assembly for coolant lines, in particular for motor vehicle air conditioning systems which are operated with CO2, from a first coupling element that can be connected to a first line end piece, and a further air conditioning circuit component. The first coupling element and the air conditioning circuit component are joined by a screw so that the first line end piece and the air conditioning circuit component are connected to one another by means of one bore each and radially extending sealing faces. A sealing ring is arranged between the faces. A space holder is arranged between the first coupling element and the further air conditioning circuit component. The first line end piece has a radially extending sealing face which is produced by plastic deformation of the line end piece without removing material. The first coupling element has an annular collar which presses the sealing face onto the sealing ring in the mounted state.
