Abstract: An aspect of the invention relates to a distributed network comprising a plurality of network nodes. The distributed network is configured to perform a method for reaching a consensus on a sequence of values in an advantageous manner. The method performs consecutive notarization rounds. The notarization rounds comprise steps of creating value proposals to be added to the sequence, communicating the value proposals to a notarization subset of the plurality of nodes and performing a validity check of received value proposals. The notarization rounds may comprise further steps of executing individual notarization signatures on a subset of the value proposals that are valid. The notarization rounds may further comprise performing a consistency check of the value proposals and executing consistency signatures on a subset of the value proposals. The method may further comprise a finality procedure to finalize a value proposal once a predefined finality rule set has been fulfilled.

Abstract: System has an optical sensor (1), an aperture with the optical element (2) with the changeable permeability and an activation light (3) emitting radiation, which is detected by the optical sensor (1). The activation light is connected with the switch (4) and it is placed within the reach of the optical sensor (1). Within a device which realizes the technological process with the luminous manifestation the instruction for the beginning of a given technological process is detected and on the basis of this instruction the activation light (3) lights up. This activates the optical sensor (1) by means of the activation light (3) before the optical sensor (1) detects the luminous manifestation of the technological process itself. The activation light (3) can be a simple infrared LED diode.
