Abstract: A computer-readable storage medium may include executable instructions stored thereon that, when executed by a processor, may be configured to establish a connection to a node of a distributed ledger network that maintains a distributed ledger. The processor may obtain a first dataset from a first user, perform pre-processing on the first dataset to obtain a first data asset based on the first dataset, and store the first data asset. The processor may calculate a first value for the first data asset and generate a first data proposition based on the first data asset. The processor may obtain acceptance data from a second user, which may include data indicating acceptance by the second user of the first data proposition. The processor may transmit a first distributed ledger record to the node of the distributed ledger network.

Abstract: A dish drainer and tray system providing reduced space requirements for packaging, shipping, display and storage. The tray may be compacted into storage size which allows it to fit in the drainer, thereby allowing the drainer rather than the combination to determine the space requirements. In one embodiment, the tray folds about one or more live hinges, and in a second embodiment the tray rolls and includes a closure to maintain it in the rolled position. A particularly preferred embodiment includes a detachable silverware compartment that drains directly into the sink and which can be stored with the tray in the drainer.
