Abstract: A computer-implemented method, system, and computer program product are provided. A processor defines and stores units of image data of a container image, where the units of image data are compressible. A processor represents the units as nodes in a dependency graph for a container image, including one or more nodes at a dependency level in the dependency graph.

Abstract: A node in a blockchain network may invoke a process comprising receiving one or more operations for inclusion in a block, receiving a previous Merkle root created from previously determined account dispositions from a previous block, resolving the one or more operations based on the previous account dispositions to determine one or more current account dispositions, creating a current Merkle root for the one or more current account dispositions, and hashing current data for the current block, the data comprising the current Merkel root and the previous Merkle root to generate an account disposition block.
