Abstract: User interface (UI) manipulation techniques are disclosed that can allow a user device to hide and obscure sensitive information displayed on a flexible, foldable, or otherwise reconfigurable display from onlookers whilst maintaining or improving its accessibility exclusively to the primary user. Examples of the disclosed techniques can manipulate the UI in a way such that it is largely only viewable as intended when the user device is physically configured to a certain folding angle (and/or viewing angle). In some examples, the UI can be customized such that it promotes a certain device configuration (e.g., folding angle) that can provide an optimum security configuration for the user's current surroundings. The UI displayed on the display screen can change in form factor (e.g., an intended size as viewed by the user) to adapt to the current surroundings and/or based on the sensitivity in the displayed content.

Abstract: A computer-implemented method is provided comprising: generating a digital data block comprising transaction data representing at least one energy transfer transaction corresponding to an exchange of charge between a community member device and a charge source device, randomly selecting, in a group of community member devices, a plurality of block verification devices, wherein the block verification devices form a subgroup of block verification devices, partitioning a block verification computation task for the digital data block into a plurality of block verification computation subtasks, assigning the block verification computation so subtasks to respective selected block verification devices, transmitting the digital data block to each selected block verification device, together with its respective block verification computation subtask over a computer network, determining that the digital data block is verified, based on at least one verification results of a corresponding block verification computation
